Повний текст джерелаDespite the benefits of adjuvant endocrine therapy (AET) for reducing recurrence andmortality risks after hormone-sensitive breast cancer, AET adherence is sub-optimal for ahigh proportion of women. However, little is known about long-term patterns of AETadherence over the minimally recommended 5 years. Our objectives were to: 1) identify fiveyear AET adherence trajectory groups; 2) describe trajectory groups according to adherencemeasures traditionally used (i.e. the proportion of days covered (PDC)); 3) explore factorsassociated with trajectories. We conducted a five-year cohort study using data from a Frenchnational study that included AET dispensing administrative data. Women diagnosed withfirst non-metastatic breast cancer and having ≥1 AET dispensing in the 12 months afterdiagnosis were included. Group-based trajectory modeling was used to identify adherencetrajectory groups by clustering similar patterns of monthly AET dispensing. Multinomiallogistic regressions were used to identify factors associated with trajectories. Among 674women, five AET adherence trajectory groups were identified: 1) quick decline and stop(5.2% of women); 2) moderate decline and stop (6.4%); 3) slow decline (17.2%); 4) highadherence (30.0%); 5) maintenance of very high adherence (41.2%). Mean 5-year PDCvaried from 10% to 97% according to trajectories. Women who did not receive chemotherapyor a personalized care plan were more likely assigned to trajectories where AET adherencedeclined and stopped. Our results provide information on the diversity of longitudinal AETadherence patterns, the timing of decline and discontinuation and associated factors thatcould inform healthcare professionals.

Повний текст джерелаCe travail de thèse a investigué ces questions au travers de deux études empiriques répondant aux objectifs suivants: (a) l’évaluation de l’évolution et des prédicteurs de l’anxiété durant le traitement de radiothérapie et (b) le développement et l’évaluation de l’efficacité de deux interventions psychologiques de groupe sur la régulation de l’anxiété après la radiothérapie.
Les résultats de la première étude (a) montrent que les niveaux d’anxiété les plus élevés sont observés lors de la simulation et de la première séance de radiothérapie et diminuent, ensuite, rapidement jusqu’à la fin du traitement. Bien que les niveaux d’anxiété soient relativement faibles pour de nombreuses patientes et semblent être de nature anticipatoire, certaines patientes présentent des niveaux cliniquement significatifs d’anxiété. De plus, un niveau cliniquement significatif d’anxiété à la première séance de radiothérapie est prédit par des facteurs liés à la communication entre les patientes et l’équipe de radiothérapie. Les résultats de la seconde étude (b) indiquent qu’une intervention de groupe à composantes multiples qui combine le soutien, les techniques cognitivo-comportementales et l’hypnose est plus efficace qu’une intervention de groupe à composante unique basée sur le soutien pour aider les patientes à mieux réguler leur anxiété après la radiothérapie.
Les résultats de ce travail de thèse soulignent l’importance d’évaluer l’anxiété chez les patientes à des moments critiques de leurs parcours médical et d’identifier les patientes qui présentent des niveaux cliniquement significatifs d’anxiété pour leur offrir un soutien adapté. Ces résultats suggèrent également d’améliorer les prises en charge afin de réduire l’anxiété des patientes. Des prises en charge offertes par les équipes de radiothérapie nécessitent une personnalisation de la communication établie avec les patientes et l’utilisation de stratégies proactives d’évaluation, d’information et de soutien. Des prises en charge psychologiques de groupe nécessitent quant à elles de combiner les composantes thérapeutiques les plus optimales. Enfin, ce travail de thèse souligne l’importance de continuer à développer et à améliorer les méthodes d’évaluation et d’intervention.

Повний текст джерелаObjective: The objective of this master’s thesis is to evaluate the wage losses incurred among spouses of women diagnosed with non-metastatic breast cancer in the six months following start of treatment. Methods: This master’s thesis is part of the study “Costs of breast cancer: extent, determinants and relation with quality of life”, which includes 829 women with non-metastatic breast cancer recruited in 8 Quebec hospitals and 427 of their relatives. To meet the objective of this thesis, we retained the relatives who were the spouse of the woman and who were employed in the month prior to diagnosis. Information to calculate wage losses (usual salary, absence duration, compensation received) was collected by telephone interviews conducted 1 and 6 months after the start of the woman’s treatments. Results: Among the 279 employed spouses, 219 (78.5%) experienced at least one absence or reduction in work hours because of breast cancer. Spouses were compensated an average of 66.3% of their salary during these absences or reductions in work hours (standard deviation = 43.5%; median = 100%). Considering all sources of compensation received, the median wage loss in the six months after diagnosis was $0 CAN 2003 (mean = $1,819; standard deviation = $5,247). Conclusion: Work absences affected the majority of spouses of woman diagnosed with non-metastatic breast cancer. However, wage losses were modest for most spouses because of compensation received.

Повний текст джерелаThe contrast between the increase in the incidence of breast cancer rate and the stability of mortality rates seen in France during the past twenty five years may be due to advances in breast cancer management and early diagnosis. The aim of this work was to assess the impact of treatment advances on survival and quality of life (QoL) in breast cancer patients. The first study was undertaken to assess prognostic factors on overall (OS) and relative survival (RS) among patients with breast cancer. The results of this study showed that TNM stage, SBR grade, progesterone receptors status, tumour multifocal status, locoregional extension and the period of diagnosis were independent prognostic factors of OS and RS. The second study was a prospective multicenter study which aimed to assess the impact of different surgical procedures on QoL in breast cancer patients. The results of this study highlighted the beneficial effect of sentinel lymph node biopsy (SLNB) on breast cancer patients’ QoL as compared to axillary lymph node dissection (ALND) when SLNB is not followed by complementary ALND. SLNB should then be the treatment of choice for patients who have early-stage breast cancer with clinically negative nodes, and operating surgeons should have a high level of technical skill. The last study was undertaken to determine the efficacy of neoadjuvant chemotherapy compared with adjuvant chemotherapy using relative survival (RS) as the primary end point. Despite a favorable trend, this population-based study showed that neoadjuvant chemotherapy was no better than adjuvant chemotherapy in terms of OS and RS of breast cancer patients

Повний текст джерелаThe conditions of use and access to medical records became an important source of interest in the last decade. Our objective was to estimate the impact of a patient-held records, shared with health professionals. Using the example of breast cancer management, we identified practitioners and patients’ expectations and we defined the size of a medical records which could be held by each patient. The synthesis of these works allowed us to set up a randomized controlled trial comparing patients with the usual follow-up and patients holding this new records containing essential information for their follow-up. The patient-held records is a source of membership and satisfaction for the patients and health professionals. It was used as a tool of communication between physicians and patients but could also cause anxiety to some patients. The patient quality of life, the data confidentiality or the care consumption remained identical. A new concept of medical records was revealed by this study

Повний текст джерелаAccording to WHO, organized screening is based on the voluntary participation of subjects who are recruited into the population through screening campaigns. In France, two are organized by the government: breast cancer screening and colorectal cancer screening. The aim of this thesis was to study by an ethical and forensic approach, the French organized programs for cancer screening.Ethical values of national screening programs are subject to European recommendations. In France, they are available in documents attached to the legal texts implementing screening programs. Some others texts more general, frame this practice in France.Detailed in a report published by INCa, the ethical analysis of organized screening program for breast cancer points the need to optimize patients’ information and to strengthen the position and role of the referring health professional, from the entry in the screening to the eventual output to the care.The study of GPs’ preferences in the organization of screening for colorectal cancer shows that issues related to patient information and procedures for collecting of consent, as well as patient monitoring, play a real impact on their adherence to the program, in terms of forensic risk
Ramos, Rodrigo Nalio. "The immunosuppressive microenvironment in cancer : local and systemic effects on patients' monocytes." Thesis, Lyon 1, 2015. http://www.theses.fr/2015LYO10270.
Повний текст джерелаIn cancer patients, the neoplastic cells escape from the immune control because of their low immunogenicity and their exacerbated capacity to modulate the microenvironment. Here we describe the local and systemic effects of the tumor microenvironment on monocyte differentiation and the impact of the presence of Tmor Associated Macrophages (TAM) CD163+ on the survival of breast cancer patients. By flow cytometry analysis, we describe a heterogeneous composition of CD163low and CD163high TAM subtypes, where we observed the association between high frequency of CD163high TAM infiltration and low CD3+ T lymphocytes presence. By immunohistochemistry on a retrospective analysis (±12 years), we have shown a strong correlation between high frequency CD163+ TAM and an increased risk of progression for patients (log-rank *p<0.05, n= 238). In vitro, CD14+ monocytes conditioned by tumor microenvironment exhibit a biased differentiation towards a CD163highCD86lowIL-10high macrophages (MΦ) phenotype, that not only failed to stimulate the proliferation of naive CD4+ T cells, but strongly inhibited the expansion and the production of IFN-γ and TNF-α by activated-CD4+ T cells. This differentiation into M2-like MΦ (CD163highIL-10high) is associated with high levels of TGF-β, M-CSF and VEGF found in the tumor microenvironment. Furthermore, circulating monocytes of breast cancer patients produced an immunosuppressive cytokine profile and are biased towards the differentiation into MΦ and Mo-DCs that show suppressive capacities
O desenvolvimento do câncer é normalmente associado a desvios no sistema imune, principalmente devido a sua falha em perceber, reconhecer e eliminar células neoplásicas de maneira eficiente. Nesse contexto, duas Células Apresentadoras de Antígenos (APCs), Células Dendríticas (DCs) e Macrófagos (MΦ), têm um papel crucial na identificação de alterações nos tecidos e na estimulação da imunidade adaptativa antitumoral. No entanto, fatores derivados de tumores modulam essas APCs, impedindo a iniciação das respostas imunes e culminando no estabelecimento do câncer. Investigamos aqui como o microambiente tumoral poderia modular a diferenciação de monócitos em APCs in vitro e de modo sistêmico. Nossos dados revelaram que em cânceres de mama e ovário, Macrófagos-Associados a Tumores (TAMs) são a subpopulação mais frequente em leucócitos CD45+MHCII+, e são encontrados em uma frequência variável de TAMs CD163low ou TAMs CD163high. O último, (TAMs CD163high) expressaram maiores níveis de PD-L1 e elevada produção de IL-10 sob a ativação de LPS. Além disso, a análise retrospectiva por imunohistoquímica revelou uma forte correlação entre a presença de TAMs CD163+ e uma baixa taxa de sobrevida em pacientes com câncer de mama. Ainda, a alta frequência de TAMs CD163high foi correlacionada com um baixo infiltrado de células T CD3+. Monócitos saudáveis condicionados por sobrenadantes de tumores de mama tiveram sua diferenciação in vitro direcionada para um fenótipo CD163highIL-10high, células capazes de suprimir a expansão de células T naive CD4+ e a produção de IFN- γ e TNF-α via IL-10. Esse fenótipo adquirido por monócitos condicionados foi associado à presença de altos níveis de CCL22, M-CSF, TGF-β1, TGF-β3, e VEGF no microambiente tumoral. Interessantemente, avaliando os efeitos sistêmicos dos tumores, monócitos circulantes de pacientes com câncer de mama falharam em diferenciar-se em M1- MΦ na presença de GM-CSF/IFN-γ e mantiveram um fenótipo alterado CD163+/-IL-10+TNF-α+

Повний текст джерелаThis PhD dissertation provides empirical evidence on many aspects of the volume-outcome relationship with regard to cancer care. In the first chapter, we explore the relationship between hospital volume activities and patient outcomes for ovarian cancer care. Using a wide-ranging set of clinical characteristics depicting patients’ degree of illness, we identified a strong volume-outcome relationship, with substantial differences in survival between patients treated in high volume and in low volume hospitals. In the second chapter, we look in more depth into what underlies the observed hospital volume-outcome relationship. More specifically, we provide evidence on the contribution of clinician decisions (i.e., which drive patient care pathways) to the causal impact of hospital volume on patient outcomes. Our findings substantiate the contribution of clinician decisions regarding the treatment option to the causal impact of hospital volume on patient outcomes, thereby offering a better understanding of this complex relationship. In chapter 3, we use a nationwide administrative dataset to evaluate the impact that centralization of care for breast cancer and ovarian cancer treatment has on spatial and socioeconomic inequalities in access to specialized care. Our findings indicate a strong and highly unequally distributed deterioration in patient access to specialized care, which highlights a major adverse consequence of such a policy. From a broader perspective, there is a need to understand the mechanisms of patient referral to hospitals to better understand the potential necessity of centralized care. The fourth chapter of this thesis provides evidence of patient preferences for cancer care using a revealed preferences framework, taking into account that patient choice sets are actually unobserved. Our findings highlight the importance of the choice set preselection, which could be related to the role of general practitioners in the referral process and substantiate several barriers to patient choice

Повний текст джерелаPopulation aging and growing incidence of cancer question access to palliative care. Integration of this care and specialized structures’ diversification (unit, mobile team, identified beds, outpatient clinics) are changing the referral’s modalities of hospital-based palliative care (HPC). This work aims to study the socio-demographic, socio-economic, tumour- and care-related predictive factors of the probability and the precocity of HPC in cancer patients. A systematic review of the literature identified factors of access around the world. Two analyses then studied the cumulative incidence at 2 years and at the end of follow-up (probability) and the mean follow-up time after HPC (precocity). First analysis was based on patients from the French cancer registers of Gironde (n = 8,424; 2014 period). The second was based on metastatic breast cancer (MBC) patients from the national ESME-CSM cohort (n = 12,375; 2008-2016 period). Regarding the analyses, the explanatory factors were age, gender, socioeconomic level, place of residency, tumour location or subtype, metastases’ characteristics and type of centre. Several methods have taken into account the competitive risk of death (Aalen-Johansen estimator, multi-state model, pseudo-values). In both populations, HPC were mostly initiated during the terminal disease. In registries’ sample (75+ years: 2,695, 32%; Males: 4,317, 51.3%; Breast: 1,247, 14.8%), the 4-year and 2-year cumulative incidence’s factors differed according to the tumour prognosis. In unfavourable prognosis subgroup, rural patients, those with haematological malignancy and older patients treated outside tertiary centres received less HPC. In favourable prognosis subgroup, older people, non-deprived patients and those with lung cancer or treated in tertiary centres received more HPC. Women and patients with high-grade central nervous system tumours had earlier referral. In the sample of ESME-CSM patients (75+ years: 2,380, 19.2%; triple negative MBC: 1,545, 12.6%), the cumulative incidence’s factors depended on follow-up period. At 2 years, HPC mainly concerned the youngest with triple negative MBC, the oldest with another subtype, relapsed patients or those with several metastatic sites. At 8 years, HPC were less frequent outside of highly-recruiting centres, in particular for older patients. HPC referral was also less early in these centres. In addition to classic disparities in care access, we have highlighted that the role of socio-demographic factors depends on cancer prognosis. The one of age also depends on care centre characteristics. Analytical studies on the mechanisms involved would be of value

Повний текст джерелаLe présent mémoire a pour objectif de développer un questionnaire qui permettra éventuellement de comparer l'influence respective des pensées négatives, positives et réalistes sur l'adaptation psychologique au cancer du sein, et ce, durant et après les traitements de chimiothérapie. Ce questionnaire a été développé de manière à avoir une structure similaire à celle du Orientation to Motherhood scale (OM; Churchill & Davis, 2010), lequel quantifie la fréquence d'occurrence de pensées anticipatoires à valence positive et négative afin de déterminer si l'orientation de pensée des répondants est davantage négative, positive ou réaliste. Ce mémoire vise également à récolter de l'information sur la nature des pensées des patientes avant la chimiothérapie. Deux étapes ont été nécessaires afin de rencontrer ces objectifs. Dans un premier temps, vingt-cinq femmes atteintes d'un cancer du sein ont pris part à une première série d'entrevues individuelles visant à générer une banque d'items potentiels pour le questionnaire (N = 15). Par la suite, une deuxième série d'entrevues a été menée afin de permettre la tenue d'une étude pilote (N = 10) et de raffiner la forme et le contenu du questionnaire. Le Questionnaire des pensées et anticipations au sujet du cancer (PAC) est un questionnaire auto-rapporté de 51 items permettant de documenter la fréquence de diverses pensées anticipatoires à valence positive et négative chez les femmes s'apprêtant à commencer des traitements de chimiothérapie pour un cancer du sein. Les résultats de l'étude pilote sont encourageants quant à la capacité du PAC à discriminer les participantes entre elles sur la fréquence de leurs pensées à valence positive et négative. De plus, les différents profils observés chez les participantes de l'étude pilote supportent l'existence d'une relation entre les réponses au PAC et la détresse psychologique. Les données préliminaires mettent également en lumière la plus forte fréquence de pensées à valence positive que négative.

Повний текст джерелаWe found that diagnosis during pregnancy does not significantly influence the classic pathological features or the prevalence of breast cancer subtypes. We also did not find obvious differences in the distribution of PIK3CA mutations. However, we found that tumors diagnosed during pregnancy have activated serotonin receptor signaling and high expression of potential breast cancer targets; of particular interest IGF1, and PDL1. Such differences appeared to be reflected in the normal pregnant breast underscoring the potential role of the pregnant breast microenvironment on the tumor transcriptome. We were not able to associate these genes with prognosis, which could be partly due to lack of statistical power. Of note, we cannot confirm whether any of these aberrations are key drivers of the biology of tumors diagnosed during pregnancy. Nevertheless, this remains the first study to look into the biology of this relatively rare disease and hence we believe it would serve as a very valuable resource for future research in this field. We are planning to perform targeted gene sequencing to further refine our understanding of the potential effect of pregnancy on the biology of these tumors.
In the last part of this work addressing the safety of pregnancy following breast cancer diagnosis, we identified that available studies suffered major limitations related to study design including selection bias and lack of information on patients with history of an ER-positive disease. This has resulted in advising against pregnancy in women with prior history of breast cancer. Our subsequent study has robustly addressed most of the limitations in older studies and clearly showed that pregnancy following breast cancer is safe even in women with a history of ER-positive disease. Hence, this study would provide a very important resource for the oncology community, which would aid adequate fertility counseling for young breast cancer survivors. This work is currently serving as the basis for a new prospective study by the IBCSG to test the safety of early interruption of tamoxifen in young women with early breast cancer seeking subsequent pregnancy.

Повний текст джерелаObjectives. The purpose of this study is to evaluate the cardio-pulmonary function as measured by VO2peak in breast cancer before treatment (CT-RT) and after the completion of a physical activity program (APA). Methods. Arm A (endurance and resistance training) and arm B (control group). This study included three evaluation time. (T0 : before CT-RT), T1 (week 27) and T2 : final evaluation at 54 weeks). The reviews are a test of cardiopulmonary exercise assessing VO2peak a walking test 6 min (6MWD) test of muscle strength, respiratory function tests, assessment of physical activity in the using the questionnaire IPAQ, fatigue (MFI 20), quality of life (EORTC QLC-C30), anxiety and depression (HADS) and finally an assessment of body composition. Results. Between June 2012 and June 2013 44 patients were included in the study. At T0, the average age was 52. 3 ± 11. 7 years for arm A and 48. 8 ± 8 for the VO2peak B. Before treatment arm was 22,5 ± 4,4 ml. Kg-1. Min-1 for arm A and 23,4 ± 5,1 ml. Min-1kg-1 for arm B. After treatment, analysis by intention to threat the difference between our two groups was 2,3 ml. Min-1kg-1, while in per-protocol analysis this difference was 3. 49 ml. Min-1kg-1 and is significant. The walking distance improved from 21,75 ± 7,15 m to arm A and decreases of 9,54 ± 6,82 m for arm B. Conclusions. Our study was able to prove that individualized training at home is feasible and safe for patients with breast cancer in the adjuvant or neoadjuvant

Повний текст джерелаGermline mutations in the BRCA2 gene lead to high susceptibility to the development of breast and ovarian cancer. The tumor suppressor protein BRCA2 is essential for preserving chromosome integrity after DNA damage emerging from endogenous or exogenous sources. BRCA2 functions in Homologous Recombination (HR), the most reliable pathway to repair DNA double strand breaks. BRCA2 exerts its tumor suppressor role also at several stages during mitosis where it ensures checkpoint control and proper cell division.Although the function of BRCA2 in HR is well established, evidence from the literature describing a partial restoration of HR function in cells lacking the C-terminal DNA binding domain (CT-DBD) brought us to test the hypothesis of a secondary DNA binding domain in BRCA2.In silico analysis of the protein revealed a putative zinc finger-PARP domain in exon 10 of the N-terminal region. This type of domain usually binds DNA which prompted us to examine this activity in vitro. Using purified N-terminal fragments comprising the putative DNA binding domain in electrophoresis mobility shift assay we demonstrated the DNA binding activity of the N-terminus of BRCA2. When compared to the canonical CT-DBD, the N-terminal DNA binding domain (NT-DBD) exhibits stronger affinity for various DNA substrates and unlike the CT-DBD, it can also associate with dsDNA. Using a DNA strand exchange assay we also showed that the NT-DBD stimulates the recombination function of RAD51. In addition, BRCA2 missense variants in the NT-DBD found in breast cancer patients showed reduced dsDNA binding and decreased stimulation of RAD51 recombination activity on dsDNA/ssDNA containing substrates, implying that these residues are important for both functions. This work revealed a novel DNA binding domain in the N-terminus of BRCA2 that, in contrast to the CT-DBD, can associate with dsDNA and promote RAD51 recombination activity. We propose that the NT-DBD positions RAD51 at the ssDNA/dsDNA junction facilitating RAD51 loading onto the RPA-coated ssDNA. This activity may promote HR in DSB repair and in daughter strand gap repair (von Nicolai, C et al., 2016 submitted).To define the relevance of NT DBD on cancer predisposition, we selected several missense variants of unknown clinical significance (VUS) found in families at high risk to develop breast cancer located in this region. We used in vitro and in vivo functional assays to study the impact of the mutations on BRCA2 function in HR and mitosis. Some of the variants exhibited hypersensitivity to DNA damaging agents and PARP inhibitors, a hallmark of defective HR while one variant was proficient in repair. All variants showed normal centrosome duplication, but exhibited delayed or failed cytokinesis. This phenotype suggests a defect of the variants in midbody formation and abscission as a consequence of impaired BRCA2 function. It remains to be established if the defects in HR and cytokinesis are related. In the future, this study will help to classify VUS in the NT-DBD and facilitate genetic counselling of individuals carrying these mutations.BRCA2 is a mediator protein in RAD51-dependent HR. Its meiotic counterpart, DMC1, shares similar structure and function and binds BRCA2. However, the functional relevance of this interaction remained elusive. In this work, we showed that through the BRC repeats, BRCA2 interacts with DMC1 and promotes joint molecule formation. This stimulatory effect is due to the enhancement of DMC1 assembly on ssDNA. Importantly, full-length BRCA2 also stimulated the DNA strand exchange activity of DMC1, confirming the results with the isolated BRC repeats. Our results identify BRCA2 as a mediator of meiotic recombination and underline the role of the BRC repeats on this function (Martinez, von Nicolai, et al., 2016, PNAS)

Повний текст джерелаTamoxifen and aromatase inhibitors are the main therapeutic options for adjuvant treatment of hormone-dependent breast cancer. High inter-individual variability of efficacy and toxicity of these drugs is observed which may be related to the variability of plasma drug concentrations. In the case of tamoxifen, its pharmacological activity depends on the formation of active metabolites, mainly endoxifen, via the cytochromes P450 (CYP2D6, CYP3A4/5, CYP2C9, CYP2C19). Concerning letrozole, it is metabolised via the CYP2A6 and CYP3A4 isoenzymes. The variable activity of CYP, due to genetic polymorphisms or concomitant use of CYP inhibitors or inducers, may impact the plasma exposure to the active compounds and in fine, the efficacy and toxicity of the treatment. The pharmacokinetic-pharmacogenetic analyses of the data from first follow-up visit in the PHACS study (prospective, multicenter, national, 2000 patients, 6 follow-up visits during 3 years) demonstrated the impact of CYP2D6 phenotype, CYP3A4*22, CYP2C19*2, and CYP2B6*6 genotypes and of the concomitant use of CYP2D6 inhibitors on tamoxifen metabolism. The longitudinal pharmacokinetic data for tamoxifen and its metabolites (6 to 36 months follow-up visits) were analysed simultaneously using non-linear mixed effects modelling (population approach). A joint pharmacokinetic model for tamoxifen and six metabolites was developed and validated. The significant covariates in the final model were: CYP2D6 phenotype, CYP3A4*22 and CYP2B6*6 genotypes, CYP2D6 inhibitors, age and body weight. Simulations of alternative dosing regimens were performed to propose an individualised dose of tamoxifen for patients at risk of subtherapeutic exposure to endoxifen. The pharmacokinetic-pharmacogenetic data for letrozole were analysed using the population approach. A one-compartment model was developed and validated. CYP2A6 activity was significantly associated with letrozole clearance. The model was used for identification of non-adherent patients based on their steady-state plasma concentrations

Повний текст джерелаBreast cancer mainly affects postmenopausal women with an average age close to 60 years, although 10-15% of younger women are affected. For these women, the prognosis is poorer, with a higher risk of non-hormone-dependent cancer, lymph node involvement or high-grade tumours. These patients are more likely to receive chemotherapy, exposing them to significant ovarian damage while they are still of childbearing age. At the same time, the characteristics of the French population in terms of fertility are also changing and the age of first pregnancy continues to decline. The majority of patients are likely to receive neoadjuvant and/or adjuvant chemotherapy, which frequently induces an alteration in ovarian status, in a drug- and dose-dependent manner. This ovarian alteration mainly results in a depletion of the ovarian reserve, that is to say a reduction in the stock of primordial follicles. This alteration in ovarian function has many consequences on the quality of life of these young women. It is currently impossible to predict the extent, duration and possible reversibility of the gonadotoxic effect of chemotherapy. This increase in the incidence of breast cancer, combined with the increase in the age of first pregnancy, underlines the need to be able to provide accurate information to women of childbearing age with breast cancer about the possible gonadotoxicity of treatments. This gonadotoxicity can therefore in some cases lead to early menopause, which in turn has many consequences and has a significant impact on the quality of life of women with non-metastatic breast cancer. The different objectives of this work are as follows: 1° The review of menopause in the context of breast cancer treatment, more particularly on the effects of chemotherapy on ovarian hormones and the consequences of chemotherapy on quality of life. This review of the literature has enabled us to highlight several essential points such as a non-standardised definition of menopause and the fact that in some cases the effects on quality of life took second place to remission. 2° To identify young patients who had received chemotherapy between 1994 and 2012 in order to analyse the incidence of premature menopause and related factors. This retrospective database showed us that of the patients selected (n=345), 46 were menopausal following treatment, i.e. approximately 13.3%. It has been shown that age at diagnosis and hot flushes are factors that increase the risk of menopause following chemotherapy treatment. 3° To set up a pilot trial, from the drafting of the protocol to the analysis of preliminary data. This pilot trial focused on "Study of the impact of the Chemo-Induced Menopause on the Quality of Life of young women of childbearing age with non-metastatic breast cancer". This work will be presented in the manuscript, I will present the results showing the impact of treatment and amenorrhoea induced by chemotherapy on the functional score of the QLQ-C30 or on anxiety, depression, and the impact of climacteric manifestations on these young women

Повний текст джерелаNeoadjuvant chemotherapy (NAC i.e. chemotherapy before surgery) is increasingly being used for aggressive or locally advanced breast cancer (BCs). Beyond clinical benefits, it represents an opportunity to monitor in vivo sensitivity to treatment. Based on the analysis of datasets of BCs patients treated with NAC, we aimed at identifying mechanisms associated with resistance or sensitivity to treatment.In the first part, we evaluated biological, clinical, pathological and transcriptomic patterns. We demonstrated that unexplored pathological features such as post-NAC lymphovascular invasion may carried an important prognostic information.In a second part, we analyzed impact of imune infiltration in BC and we described extensively the changes of tumor infiltrating lymphocytes (TILs) between pre and post-NAC samples. We showed that the prognostic impact of TILs was different before and after NAC, and was opposite in TNBC and HER2-positive BCs. Finally, we investigated the impact of comedications use during NAC. We found both positive effects - while enhancing immune infiltration and response to treatment - and negative effects with deleterisous oncologic outcomes in specific patients subgroups. In conclusion, the neoadjuvant setting represents a platform to both generate and potentially validate research hypotheses aiming at increasing the efficacy of treatment. The public release of real-life datasets of BC patients treated with NAC would represent a major resource to accelerate BC research

Повний текст джерелаNumerous studies have shown that older women with breast cancer are undertreated in comparison with the youngest. Although several reports suggest strong socio-economic and geographic inequalities in the disease stage at diagnosis and in quality of life in breast cancer patients, the effects of these factors according to age are largely unknown in France. The objectives of this work were to determine the impact of socio-economic and geographic disparities on disease stage in breast cancer patients according to age, to describe treatments and relative survival factors in breast cancer patients according to age, and to identify age-related socioeconomic and clinical determinants of quality of life among breast cancer survivors five years after the diagnosisThe results showed that living in a deprived area was linked to advanced-stage breast cancer at diagnosis only in women aged 50-74 years old. The use of breast conserving surgery decreased in older women while the proportions of women without treatment increased with age. Furthermore, survival was poor in elderly women. Finally, the results showed that, five years after breast cancer diagnosis in older women, only comorbidities and a low socio-economic status decreased quality of life scores.To improve survival and quality of life in elderly patients, a multidisciplinary approach by a comprehensive geriatric assessment, is a major step in breast cancer management as it can lead to individualized care for elderly patients with breast cancer

Повний текст джерелаIn breast cancer, numerous types of immune cells are found within the tumor microenvironment. Both pro- and anti-tumor immune-based effects have been reported. Here, we show that IL-17, a pro-inflammatory cytokine, which is produced mainly by the Th17 T cell sub-population, was strongly associated to poor prognostic markers in breast cancer patients. When analyzed at both transcript and protein levels, IL-17 was highly expressed in ER- including TNBC patients. Furthermore, IL-17 expression in tumor tissues tightly correlated with the expression of the immune checkpoint regulator, PD-L1. Interestingly, IL-17 was found to significantly induce PD-L1 expression, in breast cancer cells in vitro, at both transcript and protein levels. IL-17 also specifically triggered proliferation of distinct breast cancer cell lines in vitro, in a dose-dependent manner, which could be abolished using neutralizing antibodies directed against IL-17 receptor or IL-17. Finally, increased IL-17 levels were associated to lower survival probability in breast cancer patients, especially when combined to the ER negative status. Altogether our data strongly suggest that IL-17 is associated to poor prognosis in breast cancer patients and could be considered as a potential therapeutic target

Повний текст джерелаThere is a close relationship between breast cancer and weight. If weight excess is a risk factor for the onset of breast cancer, obesity at diagnosis and weight variations (± 5 % of initial weight) during treatement are associated with poor prognosis. Weight loss and weight gain result in an energy imbalance (energy intake and energy expenditure). The caracteristics and causes of these variations are not well described. Fat mass gain seems to be recognized as a factor of poor prognosis hence the importance to understand body composition evolution during breast cancer treatment.In this context, the aims of this thesis were to characterized weight and body compostion variation throughout treatment and to study the factors involved in the energy imbalance of which physical activity and certain components of resting energy expenditure.This thesis works have been centered around three clinical trials. Firstly, MétaCa2 trial that attempted to describe the long term evolution of weight and body composition among no-metastatic postmenopausal breast cancer patients (on average 3 years post-chemotherapy). The results of this study have shown that weight loss during chemotherapy is associated with a later weight gain during adjuvant period of treatment. This study has also demonstrated a weight and fat mass gain during endocrine therapy in the overall population and more especially for the patients with an initial fat mass excess. The increase in time spent sitting between the end of chemotherapy and the initiation of endocrine therapy has been identified has a factor associated with long term fat mass gain.Then, we have explored a hypothesis, supported by our team, suggesting that chemotherapy could have an impact on brown adipose tissue. This one is implied in the adaptative thermogenesis and so in energy expenditure and could contribute to weight gain. For this end, we realised an ancillary study to AVATAXHER trial among 109 HER2+ breast cancer patients treated with neoadjuvant chemotherapy and HER2 targeted therapy. The results have highlighted a significant decrease of BAT metabolic activity after one course of chemotherapy in the overall population and specifically in the subgroup of patients who gained weight during chemotherapy. Physical activity constitutes a possible strategy for individual prevention against weight and body composition variation. In the HER2+ subpopulation, it could also limit the cardiotoxicity of standard treatements. We have set up a prospective interventional trial in order to study the feasibility of a home-based physical activity intervention among HER2+ breast cancer patients currently treated with neoadjuvant chemotherapy + targeted therapy. The objective of the intervention is to achieve or maintain a physical activity level corresponding to the international recommendations, i.e. at least 150 minutes of moderate-intensity physical activity per week thanks to a personalised program combining aerobic physical activity and muscular strengthening.These original results have contributed to provide new knowledge about weight and body composition variation during early breast cancer treatments and also about some potential causes imply in energy imbalance

Повний текст джерелаBackground : Palliative care is a holistic approach, delivered by an interdisciplinary team, in order to improve the quality of life of people facing a serious and life-threatening illness. According to the World Health Organization and the Worldwide Palliative Care Alliance (2014), inequalities in training and lack of organization of palliative care in several countries have limited the development of nursing practice in this domain. Thus, this situation has led to disparities in the delivery of palliative care services between countries. In Lebanon, nurses are little prepared to deliver palliative care, and nursing practice in this domain is not well documented. Aim : This study aimed to understand nursing practice within an interdisciplinary team providing palliative care to end-of-life cancer patients in a Lebanese region. Framework : The study framework integrates three components that are the Plan directeur de développement des compétences des intervenants en soins palliatifs (Skill development plan for palliative care providers) (MSSS, 2008), the hindering and facilitating factors related to palliative care requirement, and Jean Watson’s Theory of Human Caring (1979). Methods : The descriptive qualitative research design chosen was a single case study with embedded levels of analysis. This study was conducted in an oncology unit of a hospital in an urban Lebanese region. Data was analyzed through a double triangulation of methods and sources, consisting of individual interview with the specialized palliative care nurse (n = 1) , with the head oncology nurse (n = 1), with oncology unit nurses (n= 9), with palliative care experts (n = 3), with family members of treated patients (n = 3) and group interview with healthcare professionals of the mobile support team (n = 3), analysis of relevant documents, direct non-participant observation of palliative nursing care, and the student’s research diary. Results : Five central themes emerged from nursing practice with cancer patients in an interdisciplinary team in Lebanon: 1) palliative care: a way to provide better quality of life; 2) nursing practice: holistic care for patient’s needs; 3) interdisciplinary: collaborative practice a main element for palliative care; 4) spirituality: a backdrop for nursing practice in palliative care and 5) family support: indispensable role of the nurse. Moreover, results have highlighted various hindering and facilitating factors of professional, organizational and emotional nature related to palliative care requirement. Nurses also demonstrated a humanistic relation marked with caring at the core of palliative care, which transcends all five central themes. Discussion : This study allowed shedding light on nursing practice in palliative care within an interdisciplinary team. Results could provide empirical foundations for informing the development of nursing practice in palliative care in Lebanon and ensure better end-of-life care for patients. Key words: Nursing practice, Palliative care, Interdisciplinarity, Caring, Facilitators, Barriers, Qualitative research, Case study.
