Resumen
The article analyzes the plays of a major representative of Kyrgyz literature, playwright, public figure Sultan Raev from the point of view of artistic reality. In origin, each piece of art is an entire structure with a fully completed head and legs. There should also be a succession network. Considering that the largest type of epic genre is drama, which is in historical and evolutionary development, the most prone to transformation and modification in accordance with the requirements of time, time, epoch, the drama of the countries of Central Asia: Kazakhstan, Uzbekistan, Tajikistan, Turkmenistan and Kyrgyzstan with new authors, new themes is filled and promotes common values not only of the Turkic people, but also of a human being, thereby the author raises topical issues. Sultan Rayev’s drama “The Long Way to Mecca” touched upon such complex issues as human purification, self-knowledge, finding your way in life, responding to what you have done, liberation from sin, and the magical connection between man and God. In the dramas “Tears of the Queen” and “The Crown», where the symbols of the absurd and the genre prevail, the historical theme is touched upon. Three dramatic works by the author were taken as research materials: “Tears of the Queen”, “The Crown” and “The Long Way to Mecca”. Hermeneutical, comparative typological, and semiotic methods were used in the analysis of these works. In the course of the study, we identified similarities and differences in comparing the author's plays, and also identified the semiotic aspect of the drama based on the analysis of characteristic features: takara, sand, black stone, crown, tumar.

Resumen
Bakgrund: I Sverige drabbas 8000 kvinnor av bröstcancer varje år. Dessa kvinnor utsätts för både kroppsliga och emotionella biverkningar och förändringar. Syfte: Syftet med denna litteraturöversikt är att belysa hur kvinnor som drabbas av bröstcancer upplever att deras sexualitet påverkas av sjukdom och behandling. Metod: Metoden var en litteraturstudie. Resultat: Ett huvudtema framkom en förändrad identitet; och fem subteman: kroppsliga förändringar, känna sig okvinnlig, relationens betydelse, kommunikationens betydelse för att komma vidare och sjukvårdens betydelse. Slutsats: Resultatet visade att kvinnorna upplevde att de förlorat sin sexuella identitet och sin kvinnlighet. Förlusten gjorde att de inte kunde identifiera sig med den kvinna som de tidigare varit. De upplevde flera fysiska förändringar som ledde till minskad sexuell aktivitet. Men trots den minskade sexuella aktiviteten upplevde många av kvinnorna en ökad närhet till sin partner och stödet från en partner ansågs viktigt. Många kvinnor saknade dock stöd och information från sjukvården angående sexuella problem. De upplevde att vårdpersonalen tyckte det var genant eller oviktigt att tala om kvinnornas sexualitet. Då sjuksköterskans primära mål är att främja hälsa och välbefinnande bör sjuksköterskan beakta kvinnornas sexualitet eftersom sexualiteten är en viktig dimension för upplevelsen av hälsa.
Background: In Sweden 8000 women are afflicted by breast cancer every year. These women are subject to both physical and mental side effects and alternations. Aim: The objective of this literature review is to highlight how women in the case of breast cancer experience that their sexuality is affected by the disease and treatment. Method: The method is a review of the related literature. Results: One major theme emerges: a changed identity, and five minor themes: physiological changes, feeling unfeminine, the significance of relationship, the significance of communication in order to move on, and the significance of medical care. Conclusion: It turns out that these women experienced a loss of their sexual identity and their femininity. The deprival resulted in an inability to identify themselves with the women they once were. They also experienced physiological changes, e.g. dryness of the vaginal mucous membrane, pain from the removed breast, and less sexual arousal which impeded and reduced the sexual activity of the women. But despite reduced sexual activity, many of these women experienced acquiring a greater proximity to their partner, and that the support from a partner was regarded as important. Many of the women, though, lacked support and information from the medical institutions concerning sexual problems. They experienced that the medical staff thought that conversing upon the women’s sexuality was something embarrassing or of no importance. Since the primary objective of the nurse is to promote health and well-being, the nurse should take heed to and attend to the sexuality of the women, considering that sexuality is an important dimension in regard to experiencing health.

Resumen
The successful treatment of breast cancer is limited due to a fraction of tumor cells escaping drug-treatment by entering a dormant state, only to relapse years or decades later at distant sites. Host-driven chronic inflammatory cells such as M2 macrophages play an important role in tumorigenesis, but the role of tumor-intrinsic inflammatory signaling involved in tumor dormancy and recurrence is unknown. We sought to determine the role of tumor-intrinsic inflammatory pathways in mouse mammary carcinoma cells (MMC) treated with Adriamycin (ADR), a clinically relevant chemotherapeutic drug. We found that ADR-induced dormant tumor cells autonomously produced pro-inflammatory cytokines, in vitro. MMC treated with Chloroquine (CQ) prior to ADR treatment displayed a delay in relapse, or prolonging of dormancy, when compared to ADR-treated MMC. Additional gene array data showed predicated activation of NF-κB p65 in ADR-treated dormant MMC that eventually relapsed. These data suggest that the anti-inflammatory function of CQ led to prolonged dormancy. To test this, we investigated the role of inflammatory signaling pathways directly by shRNA-mediated knockdown and CRISPR-Cas9-mediated knockout of NF-κB p65 in MMC. We found that knockdown of NF-κB p65 resulted in fewer dormant cells after ADR treatment and reduced rate of relapse, in vitro. NF-κB p65 was also found to reduce the immunomodulatory effects of ADR, with shNF-κB p65 showing increased upregulation of neu upon ADR treatment. Additionally, we found NF-κB p65 to be associated with a higher infiltration of CD8+ T cells and anti-tumor T cell responses. Our findings suggest a dual role of tumor-intrinsic NF-κB p65 pathway, allowing for escape from drug treatment through dormancy which leads to relapse, but also for proper lymphocyte infiltration and subsequent anti-tumor activity.

Resumen
Prostate cancer is a highly heterogeneous disease and its manifestations can vary from indolent localized tumor to widespread metastases. This heterogeneity is also observed at the molecular level both inter- and intra-patient. Intra-patient heterogeneity in the clinical setting of men with castration resistant prostate cancer (CRPC) might be informative in terms of treatment decision. Here I present analytical work on two approaches relevant to the characterization of intra-patient heterogeneity and applied to unpublished CRPC patients sequencing data. The first is based on the genome wide interrogation of multiple metastatic and primary tissue biopsies from single patients. I present genomic analyses to decipher the content of multiple tumor biopsies from CRPC patients and provide comparisons to highlight similarities and differences and to identify alternative patterns of aberrations. The second approach, alternative to tissue biopsies that might under-represent the genomic landscape of the patient’s disease, relies on liquid biopsies, a minimally invasive test that is also amenable to serial sampling. Liquid biopsies contain circulating cell free DNA (cfDNA) released from widespread tumor cells, potentially uncovering the full tumor landscape. By using next generation sequencing on cfDNA obtained from plasma, I developed strategies aimed at systematically tracking the reiterative process of genetic diversification leading to disease evolution and to detect genomic aberrations. I specifically focused on an ad hoc computational procedure (ABEMUS) to detect somatic point mutations that could emerge under treatment pressure and as drug resistance mechanism. The work I present is relevant to the context of precision oncology that exploits detailed patient-specific molecular information to diagnose and follow cancer progression with the ultimate goal of promptly guiding treatment decisions to improve clinical outcome with transdisciplinary strategies. The analytical work I developed can be applied to the study of any tumor type.

Resumen
Los tumores mucosos apendiculares tienen baja incidencia y comúnmente se diagnostican en el estudio anatomo-patólogico después de la apendicectomía. Se reporta el caso de una mujer de 41 años de edad, con un cuadro clínico de ocho meses de evolución, caracterizado por dolor abdominal de tipo opresivo, difuso y de gran intensidad en el hemiabdomen inferior, acompañado de náuseas. Después de cinco meses de iniciado este cuadro clínico, se evidenció una masa en la fosa iliaca derecha; el dolor se agudizó e intensificó, y las náuseas continuaron, por lo cual fue remitida al hospital. En los exámenes practicados se observó una masa quística compleja abdomino-pélvica de origen indeterminado, y la tomografía computadorizada de abdomen fue sugestiva de mucocele apendicular. Con estos hallazgos, se optó por el tratamiento quirúrgico por laparotomía, consistente en hemicolectomía derecha, con resección parcial de íleon, epiplectomía, histerectomía y salpigooforectomía bilateral.

Resumen
The tumor growth strongly depends upon the availability of nutrients. Many experimental evidences recently indicated that stress play important role in tumor invasion. The growth-induced stress is from pressure imposed on tumor by surrounding tissues due to tumor expansion invasion. This paper introduces a model to characterize growth-induced stress in solid tumor by analogy with thermoelasticity theory. The model is composed of a nutrients diffusion equation and a stress evolution equation. The solid spheroid tumor stress distribution induced by tumor spatial non-uniformity growth is studied. Moreover, the mechanical interactions between the solid tumor and the surrounding host tissue are discussed detailed.

Resumen
This paper presents and investigates the tumor growth based on a phase model. The tumor core is necrotic and inhibitor chemical species are considered. The interface of tumor and health tissue is tracked using a phase field equation. The reformulation of a classical model, accounting for cell-proliferation, apoptosis, cell-to-cell and cell-to-matrix adhesion, is derived. The advantages of the finite difference methodology employed are generality and relative simplicity implication. We present simulations of the nonlinear evolution of growing tumors morphology and discuss the effects of tumor microenvironment. Mechanisms reflecting the tumor growth and development behavior was preliminarily interpreted. Recently numerous mathematical have been developed to investigate the growth dynamics of tumor [1–8]. One of most significant model developed by Wise [8] is based on Cahn-Hilliard equation, which is conservation phase field method. Allen-Chan nonconservation phase field has been developed to track the moving interface for multiphase simulation by Sun [9]. Allen-Chan equation is second order, while Cahn-Hilliard equation is fourth order in space. Thus, we introduce the Allen-Chan phase method [9–10] to simulate the tumor growth, which is very simple for numerical simulation The computation domain is illustrated in Fig. 1, where ΩH denotes host tissue, the tumor domains is comprised of viable tumor cell ΩV and dead tumor cell ΩD. The numerical results are presented at Fig. (2–4). One can find that the growth of tumor strongly depend on the nutrients and nonlinear unstable growth may lead to finger shaped pattern, which is in agreement with recent experimental observations [7] of in vivo tumor. In summary, a phase method has been developed to study diffusion and consumption of the nutrients and tumor cell proliferation, necrosis and migration, which discloses the evolution of complex shape of tumor.

Resumen
Objective: Cancer is still a complex and debilitating disease even though advances in treatment have occurred. Triplenegative breast cancer (TNBC) is an aggressive subtype of breast cancer with a poor prognosis and occurs more frequently in young women. Due to its metastatic features and unique tumor microenvironment, TNBC treatment is limited. In this study, we evaluated how three chemotherapy drugs could be used to produce vaccines with cells under immunogenic cell death. Methodology: For that, 4T1-luc2 cells were treated with cisplatin (100 μM), mitoxantrone (MTX) (15 μM), and doxorubicin (DOX) (50 μM) for 24 h. Then, the treated cells were injected subcutaneously in tumor-bearing Balb/c female mice, after the tumor challenge. The treatment occurred three times, once a week. During and after the treatment, primary tumor and metastatic progression were followed using the chemiluminescence technique. After 5 weeks of the tumor challenge, mice were euthanized and organs (liver, tumor, lungs, and spleen) were collected for analysis. Additionally, the spleens were processed for flow cytometry for regulatory T lymphocyte and myeloid-derived suppressor cells analysis. Results: Cisplatin and MTX vaccines slowed the primary and metastatic tumor growth as well as the decreased tumor, liver, and spleen weight, while the DOX vaccine slowed the metastatic tumor progression in the lungs but did not alter tumor and other organs’ weight. Moreover, cisplatin and MTX vaccine increased the ratio of lymphocytes in the spleen but not the DOX vaccine. All comparison was done regarding the tumor-bearing mice treated with PBS. Conclusion: Taken together, both MTX and cisplatin vaccines treated primary and secondary tumors probably by the increase of lymphocyte recruitment, and the cisplatin vaccine also has an influence on the tumor microenvironment. Finally, the therapeutical vaccine might be an interesting approach as a treatment for TNBC due to its positive effect on metastasis and tumor microenvironment, especially with cisplatin.

Resumen
As is well known, the blood flowing through large blood vessels acts as a heat sink and plays an important role in affecting temperature profiles of heated tissues [1]. In hyperthermia, heating is usually limited to the tumor and a small margin of the surrounding tissue. Since the temperatures in the rest of the body remain normal, the blood that supplies the tumor will be relatively cold. Consequently, the blood flow inside a large vessel will represent a sink which cools the nearby heated tissues and then limits heating lesion during tumor hyperthermia. Under this adverse condition, a part of vital tumor cells may remain in the thermally lethal area and lead to recurrence of tumors after hyperthermia treatment. More specifically, tumor cell survival in the vicinity of large blood vessels is often correlated with tumor recurrence after thermal therapy. Therefore, it is difficult to implement an effective hyperthermia treatment when a tumor is contiguous to a large blood vessel or such vessel transits the tumor. How to totally destroy tumor cells in the vicinity of large blood vessels has been a major challenge in hyperthermia [2].

Resumen
The efficacy of cancer chemotherapeutics could be greatly enhanced by thermally targeted nanoparticle liposome drug delivery system. The tumor microvasculature response to hyperthermia and its permeability to the nano-liposomes were studied using the 4T1 mouse model and confocal fluorescence microscopy. Based on the experimental results, a new theoretical model was developed to describe the distributions of both the liposomal and free drug released as liposomes broke in tumor for treatment evaluation. In this model, the tumor was divided into two regions: peripheral and central. The drug effect on the tumor cell apoptosis and necrosis was considered. Upon the experimental validation, the model was used to simulate drug distribution in the tumor under either the hyperthermic or the alternate freezing and heating condition. Results showed that hyperthermia alone only enhanced drug accumulation in the tumor periphery and therefore more serious tumor damage induced in the region. But the tumor cells in the central region were hardly damaged due to the lack of drug diffusion. The alternate freezing and heating was proposed to aid the nanoliposomal drug delivery, and better results were found.

Resumen
An alternate thermal physical treatment was developed to destroy tumor tissue using liquid nitrogen cooling and RF heating treatment in our pervious study. Our pervious reports had shown that anti-tumor immunity was induced by the alternate treatment. Myeloid derived suppressor cells (MDSCs) are a subset of heterogeneous, bone marrow derived hematopoietic cells that accumulate in the spleen, bone marrow, blood and tumor sites of tumor-bearing mice and cancer patients. MDSCs are one of the key suppressor cells that regulate anti-tumor immune responses in tumor-bearing hosts. MDSCs have been shown to inhibit the function of various types of cells mediating anti-tumor immunity, such as T cells, B cells, NK cells and dendritic cells. MDSCs are recruited specifically to the tumors and contribute indirectly to angiogenesis, growth and metastasis. MDSCs also exert resistance to cancer therapies, such as anti-VEGF strategies and cancer immunotherapy. Given the role of MDSCs in tumor invasion and metastasis and anti-tumor immune responses, therapeutics targeting MDSCs might offer a new strategy for cancer treatment. In this study, the therapeutic effect and MDSCs changes after the alternate cooling and heating treatment was studied using the 4T1 murine mammary carcinoma, a common animal model of human metastatic breast cancer. Due to its highly invasive and poorly immunogenic characters, the 4T1 tumor could cause death even after the primary tumor was surgically removed. The treatment was carried out when micro-metastases were well established. Comparisons were made with the results from the surgery and hyperthermia groups, respectively. The results showed that MDSCs in blood increased rapidly with time after tumor inoculation, and in 66 days, all the mice died in the control group. The statistical results indicated a significant increase in circulating MDSC numbers at different tumor growth stages. In the surgical resection group, MDSCs in blood did not decrease, but increased rapidly to a level much higher that of the control group in 39 day after tumor inoculation. In the hyperthermia group, MDSCs in blood increased rapidly with time after tumor inoculation, and in 39 day, MDSCs was up to 3 times higher than that of the control group. Mice died in 45 day after initial tumor inoculation. But in the alternate treatment group, the number of MDSCs decreased rapidly and recovered to the normal healthy level in 11 days after the treatment. No metastatic tumor could be observed in these mice, and they were in good physiological conditions as observed in the following 3 month. In conclusion, the alternate treatment was found extremely effective against MDSCs in the very aggressive and highly metastatic mouse mammary carcinoma. The good prognosis was expected in relation to the significant decrease in MDSCs and thus the relief of the immune suppression, induced by the alternate cooling and heating treatment. It could be further developed as a novel therapeutic method against metastatic tumor. On the other hand, combining the alternate treatment with other strategies, such as anti-VEGF and cancer immunotherapy, the best therapeutic effect would be achieved through synergy.

Resumen
Introduction: Krukenberg tumor of ovary is a rare clinical entity and accounts for 1-2% of all ovarian tumor. Stomach is most common primary site but other organs can also serve as a primary site. Accurate diagnosis of krukenberg tumor requires thorough endoscopic and histopathological examination to exclude primary tumor. Case Report: 32 years old female presented with AUB for 2 months and history of jejunum carcinoma which was an incidental finding on biopsy after a surgery for intestinal obstruction. Endometrial biopsy showed endometrial carcinoma of mucin secreting signet ring type. CECT showed bilateral adnexal masses. Staging laparotomy was planned but due to dense adhesion and bladder and bowel infiltration optimal debulking could not be done and tumor was removed as much as possible. Patient was reffered for chemotherapy. Conclusion: Krukenberg tumor is uncommon metastatic signet ring cell adenocarcinoma of ovary with transcoelomic spread. It is essential to rule out other ovarian malignancy to avoid the misdiagnosis and management of krukenberg tumor.

Resumen
Delivery of drugs to solid tumors is often impeded by the elevation of the interstitial fluid pressure at the tumor core and the loss of plasma from the tumor to the surrounding normal tissue. Interstitial pressure in tumors is abnormally high because tumor blood vessels are highly permeable relative to their normal counterparts and tumors lack functional lymphatic vessels that can absorb the excess fluid loss [1]. As a result, there is a net outward flow of plasma-like fluid through the interstitial spaces of the tumor toward the exterior of the tumor where functional lymphatics may be found (Fig. 1).

Resumen
Newly developed cancer therapies must pass through a series of increasingly complex testing regimens before obtaining FDA approval as valid treatments. The costs of these tests increase rapidly as the physiological accuracy of the platform increases, from initial proof-of-concept in static tissue cultures, to treatment of animal models, and ultimately to human clinical trials. Three-dimensional engineered blood-perfused tumor models are becoming increasingly important as intermediate platforms for the study and treatment of cancer, as they are superior to static two-dimensional cultures in their reproduction of relevant physiological conditions and are inexpensive in comparison to animal models. Because of this, the design of well-characterized adaptable in vitro vascular tumor models has become a central objective of the emerging field of tumor engineering. Characterization of the flow within three-dimensional tumor models is critical for quantifying fluid shear stress and determining its role in pivotal tumor development processes such as tumor cell angiogenesis and metastasis. Ultimately, this knowledge will provide new avenues for therapeutic modulation of the tumor microenvironment.

Resumen
Photodynamic therapy (PDT) is currently being developed as a new therapeutic modality with minimal side effects in the treatment of many different types of cancers [1]. PDT requires three essential components, which includes a photosensitizing agent, activation light, and molecular oxygen [2, 3]. Light is one of the governing components for PDT, and the only component that can be controlled externally [4]. The understanding of light penetration in a tumor is critical for an efficient PDT protocol. A well-designed PDT protocol provides minimal microvascular damage and efficient killing of malignant tumor cells [5–7]. The depth of light penetration in a tumor depends on the microvascular nature of the tumor, amount of solid and liquid contents present, and the wavelength of the light source. The first two factors depend on the nature of the tumor tissue and therefore the optimal light dose is not standard for all tumors. Furthermore the liquid content of a tumor changes with the tumor temperature due to vasodilatation, and this in turn affects the depth of light penetration.

Resumen
Background: Laryngeal cancer is relatively uncommon in Ecuador. Usually epithelial in origin, the most frequent histological type is squamous cell carcinoma. The most common mesenchymal tumor is chondrosarcoma. Most laryngeal chondrosarcomas are treated with total laryngectomy, but a conservative function sparing resection is recommended in low-grade limited tumors. Case Report: In a 68-year-old female nonsmoker patient, a small tumor was found in the posterior left aspect of the cricoid cartilage in a computed tomography (CT) performed immediately after an unexpected difficulty to pass the endotracheal tube for a thoracoscopic biopsy of 4 cm tumor of the left lung, in another hospital. The patient underwent, then, an initial tracheostomy, a total thyroidectomy for a goiter and a biopsy of the tumor of the cricoid cartilage whose pathological study was inconclusive. One month later, a low-grade neuroendocrine pulmonary tumor was completed resected. Two years later, a CT scan showed the cricoid lesion with the same characteristics. At endoscopic video laryngoscopy, two subglottic masses that narrowed the airway in approximately 60% of the normal caliber, were observed located at the posterior and left walls. An intraluminal resection was performed through a transcricoid anterior approach. The pathological diagnosis was a low-grade chondrosarcoma. Tracheal decannulation was performed one month later. At an endoscopic video laryngoscopy performed six months post-operatively, the tracheal caliber and mucosa were normal. The patient remained with normal voice and breathing. Conclusion: We report the second case of chondrosarcoma of the larynx in our country, treated by a conservative approach.

Resumen
Background: It is well known that edema can persist after meningioma resection, and sometimes it is not resolved after this time. This study aimed to establish the relationship between a series of variables associated with meningioma or surgery, and the duration of postoperative edema. Methods: We conducted a retrospective study of 77 meningiomas resected at our institution between January 2016 and January 2018 with a maximum follow-up period of up to three years. The independent variables collected were demographics, tumor location, relationship with the sinuses (invasion/contact), relationship with arterial structures, deviation from the midline, volume (cm3), degree of initial edema, WHO histological classification, degree of atypia, degree of resection, previous embolization, and development of complications. The edema levels were classified according to the classification described by Ide et al. (1995): GR0, GR1, and GR2. Measurements were performed using FLAIR magnetic resonance sequences. Statistical analyses were performed using the SPSS 21. Results: Age (p=0.003), deviation from the midline (p=0.001), and tumor volume (p<0.001) were correlated with outcome using Spearman's test. Univariate analysis revealed that the localization (p=0.016), initial edema (p<0.001), degree of atypia (p=0.019), and presence of previous embolization (p=0.037) were statistically significant. In multivariate analysis, only age, initial edema, and embolization were significant independent predictors. Conclusion: These results suggest that the degree of initial edema, midline deviation, tumor volume, tumor location, degree of atypia, and previous embolization may be important predictors of postoperative edema duration.

Resumen
Review question / Objective: Which radiological factors associated with incomplete cytoreduction (gross residual disease) after cytoreductive surgery (CRS) for advanced ovarian cancer? Condition being studied: Findings of CT scan and discussion in the multidisciplinary tumor board meeting (MDO) are crucial to determine the therapeutic strategy for individual ovarian cancer patients. Preferably, patients undergo primary cytoreductive surgery (CRS) followed by adjuvant chemotherapy. However, when complete cytoreduction is not considered feasible, neoadjuvant chemotherapy followed by interval cytoreductive surgery and adjuvant chemotherapy is indicated. In patients with advanced stage epithelial ovarian cancer (EOC), maximal cytoreduction to no gross residual tumor (complete cytoreduction) is known to associated with the best overall survival.
