Full textColorectal cancer could be presented as bowel obstruction in 10-30% of cases. Up to 15 years ago, the treatment of this condition was surgical in emergency. Colic resection in two steps, colic resection with intraoperative washing with possible protection by ileostomy, and colic resection according to Hartmann are possible strategies. A consensus about what could be the best option has never obtained, because the choice depends on the age, the grade of obstruction, the comorbidity, electolyte imbalances, nutritional status and what the surgeon prefers. However the obstructive status and the urgent surgery increase complications and mortality compared to elective colic surgery. The ability of self-expanding metal stent to recanalise the stenosis and to solve the obstructive status has recently revolutionized the therapy of neoplastic colic stenosis. The colic stenting is safe, effective, with a very low mortality and morbility and it's cheaper than the surgery. For inoperable patients colic-stending is the first choice of treatment and it replaces the colic surgery and avoids the permanent stomy. For operable patients it's surely preferable to the colic surgery in two steps because it avoids the surgery and the possible stomy; compared to the only resection with intraoperative washing, in the absence of randomized clinical trials, it allows the realization of a safer colic surgery because it is realized after the resolution of obstructive status and general condition of patient. It allows a better quality and dignity of life avoiding the permenent stomy and exposing the patient to a lower surgical risck.

Full textColorectal cancer (CRC) is the 2nd cause of cancer-related death. Despite standard therapies, more than 50% of patients experience relapse, eventually with metastatic disease. The CRC microenvironment is densely infiltrated by T cells, which have a role in immune surveillance and modulation of tumor progression, and their presence correlates with improved overall survival. To counteract immune exhaustion, inhibitory receptors (IRs) blockade has been exploited, but efficacy was limited to a small group of CRC patients characterized by high mutational burden. Adoptive T cell therapy (ACT) with genetically engineered T cells could represent an innovative strategy to harness T cell function and specificity. Initially relying on isolation, ex vivo expansion and re-infusion of tumor-infiltrating T cells (TILs), the development of ACT cellular products has now been prompted by the newest gene transfer and genome editing techniques. However, the widening of ACT with genetically engineered T cells is still limited from by paucity of anti-tumoral T cell receptors (TCRs) and by the need to counteract the immune-suppressive tumor microenvironment (TME). This work aims at setting the basis for the development of effective T cell products for the ACT of CRC, endowed with the capacity to specifically recognize cancer cells and counteract the immune-suppressive CRC TME. We employed high-dimensional flow cytometry coupled with an advanced pipeline of data handling by dimensionality reduction and clustering algorithms to describe the phenotype and the exhaustion features of TILs retrieved from the healthy, peritumoral and neoplastic tissue of treatment-naïve primary CRC patients and from the peritumoral and tumoral tissue of CRC patients undergoing surgery for liver metastasis. Unsupervised analyses highlighted the co-expression of multiple IRs and activations markers in T cells within the tumors. Populations of TILs described by a peculiar IRs signature were enriched both in primary CRC and liver metastasis. Of note, the signatures retrieved from primary and metastatic CRC overlapped for the upregulation of PD1 and CD39 thus underlining these molecules as relevant targets for T cells engineering. With the aim of exploiting this exhaustion signature to retrieve new anti-tumor specificities, we performed TCRαβ sequencing on PD1+CD39+ T cells isolated from primary CRC samples, obtaining different results from MSS and MSI tumors, where the repertoire was more oligoclonal. Of note, a small but consistent subpopulation of PD1+CD39+ T cells was also enriched in the peripheral blood of CRC patients compared to healthy donors (HDs), suggesting that exhausted tumor-specific T cells might circulate although at low frequencies. This signature could thus be used to isolate CRC-specific T cells and TCRs. As an alternative approach, we exploited a strategy to isolate CRC-specific T cells starting from HD peripheral blood mononuclear cells (PBMCs). We repetitively stimulated HD PBMCs with autologous antigen-presenting cells loaded with a pool of peptides selected to be immunogenic and expressed by CRC. We efficiently expanded T cells specific for tumor-associated antigens and neoantigen epitopes and we sequenced their TCR. To set up a T cell genetic modification pipeline, we employed a published MUC-1 TCR. We used CRISPR/Cas9 to render T cells completely devoid of the endogenous TCR, and we redirected T cells specificity by lentiviral transduction, obtaining MUC-1 specific T cells functionally able to kill target cells. Moreover, we set up the efficient disruption of PD1 and CD39 by CRISPR/Cas9 with the aim of rendering T cells selectively resistant to CRC TME. Overall, by coupling these findings we aim at generating a library of T cell products able to specifically recognize tumor antigens and to counteract the immune-suppressive TME, to be tested in adoptive T cell therapy trials for the treatment of CRC.

Full textColorectal carcinoma is the second leading cause of cancer-related death in Western countries. Surgery continues to play a key role in the treatment of this cancer. The primary goal of the surgical treatment is to ensure an adequate margin of radial and longitudinal section free of disease but also a clearance of regional lymph nodes. In fact, the nodal status represents an important predictor of survival. The presence of metastatic lymph nodes can identify patients, at highest risk, who may benefit from an adjuvant treatment. An adequate lymph node evaluation is indispensable for the staging and treatment. The number of lymph nodes, which is necessary to consider the surgical resection optimal, is still a controversial topic. A minimum of 12 negative lymph nodes is necessary to stage the N0 disease. The number of lymph nodes isolated and examined, however, is the result of a combination of different variables attributable to the patient, the tumor, the surgeon and the pathologist. As for the surgeon-dependent factor, scientific literature emphasizes that a standardized surgery based on the mobilization and careful dissection of the tissues along the anatomical and embryological plans, may increase the extent of lymphadenectomy and the accuracy of staging, reduce the risk of local recurrence and influence the prognosis and survival. It must be emphasized that the treatment of colorectal carcinoma is multidisciplinary but the impact of multidisciplinary treatment modality is optimal if the surgical operation is conducted with methodological rigor and lymphadenectomy, besides having a role in terms of staging, a purpose intended as a curative radical surgery on the one hand and assessment of the shift in the level on the other, becomes also an indicator of the quality of the surgical treatment.

The alterations in the expression of microRNAs is a common feature of cancers. The oncosuppressor miR-101 is hardly expressed in tumor samples and is a candidate biomarker in colorectal cancer. It is regulated under a number of physiological and pathological conditions, including angiogenesis and tumors. Little is known about the molecular factor involved in the regulation of miR-101 expression, because it has 2 unknown genetic loci. The aim of this work is the characterization of miR-101 genes and shed light on its molecular regulators involved in colorectal carcinogenesis.

Full textColorectal cancer is one of the most frequent cancer, with a high mortality rate, caused by the interaction of genetic and environmental factors. Parallel to the stochastic model, according to which all tumor cells (CT) have the same probability of regenerating a tumor, there is a new model that look in a very small subset of cancer stem cells (CST) the responsible of tumor growth. In the literature, CSTs shows important deregulations on genes implicated in: chemo-resistance, epithelial-mesenchymal transition (EMT), uncontrolled self-renewal, peculiar processes of this small subpopulation, which favor the onset of a tumor phenotype . The aim of my PhD project was to isolate and characterize CSTs both from tumor cell lines and from colorectal cancer biopsies, in order to identify tumor markers useful for delineating the phases of tumor progression and identifying potential therapeutic targets. In addition, I treated the CT and CST of a line of colorectal adenocarcinoma (HCA7) with the natural extract of T. cordifolia, a plant used in Ayurvedic medicine, and one of its active ingredients, berberine, in order to verify its antitumor efficacy. I observed important deregulations in treated cell populations, dependent on several genes involved mainly in EMT, in cell cycle regulation and apoptosis, but also in promoting a chemo-resistant phenotype. The expression levels of these genes were found to be significantly under-expressed, both in the treated CTs and in the treated CSTs. The results I have obtained are in favor of a potential active role of the investigated natural substance, in countering many of those fundamental processes for the development of a tumor phenotype. Furthermore, my data also support the hypothesis that CSTs are potential therapeutic targets for the purpose of achieving a targeted effect on this cell tumor population.

Full textColon cancer is the third most common malignancy in the Western countries for incidence and mortality and it is one of the best characterized molecular models of cancer progression. Recently, the role of tumour microenvironment soluble mediators has emerged as an important factor in modulating the action of proteins involved in cell survival and cell death, promoting cancer progression. In this study, we have analysed the expression of proteins involved in DNA damage repair, in cell survival and in cell death in the adenoma-carcinoma sequence of colon cancer. Moreover, we have evaluated the role of the pro-inflammatory cytokine IL-6 (present in the bowel chronic and acute inflammatory state) on the modulation of the expression of Bax, Ku70, Ku86 and Clusterin and on their interactions. We have demonstrated that the action of IL-6 microenvironment factor occurs through altered expression or localization modifying the function of proteins involved in DNA damage repair and cell survival. Hence, the action of these factors is flexible and adaptable to the diverse stages of tumour evolution. Finally, we have assessed the possible correlation between the over-expression of the secreted form of Clusterin (sCLU) observed in the most aggressive tumours and its release in circulation. The presence of sCLU has been evaluated in the blood and stool of colon cancer patients and in individuals without bowel neoplasia. We conclude that the level of secreted Clusterin has a prognostic value for colon cancer.

Se realizaó un estudio retrospectivo en 20 pacientes intervenidos de MHCCR entre Enero del 2002 y Diciembre de 2009, en el que analizamos factores de supervivencia preoperatorios, intraoperatorios y postoperatorios. El seguimiento fue de 55 ± 3 (intervalo, 12-124) meses. La mortalidad postoperatoria fue del 5% y la morbilidad, del 10%. Entre los factores preoperatorios analizados, la edad > 65 años y el tamaño de la metástasis > 5 cm fueron factores de mal pronóstico independientes, mientras que dos factores significativos de mal pronóstico fueron obtenidos del análisis postoperatorio: microsatelitosis y cifras postoperatorias de CEA > 5 ng/ml (al 1 mes). Se ha encontrado que el sexo, la localización del tumor primario, el tipo de resección, y localización de las metástasis y el CEA pre operatorio son factores que no tienen importancia pronóstica. Se concluye que la cirugía de la Metástasis Hepática ha demostrado ser segura y eficaz. Sin embargo, en pacientes con MHCCR es necesario tener en cuenta los factores postoperatorios que pueden informarnos acerca de la agresividad del tumor y de la eficacia de la cirugía.
