Diagnosis and treatment of neuroendocrine carcinoma of the thymus (NECT) is the significant problem in oncology. On the clinical course these tumors are much more aggressive than epithelial tumors of the thymus. In most of observations in NECTs there is pronounced macro- and microinvasion in the mediastinal tissue and in 30% of patients there are reveled remote metastases. The study included 17 NECT patients. Surgery is the only radical method in the treatment of such patients. 17 NECT patients were operated, 3 of them were operated again due to incomplete operations in other clinics. The vast majority of patients (58.8%) at the time of visiting had advanced stage of the disease. Out of the entire group in 7 patients NECT was associated with ectopic syndrome of varying severity. According to long-term results after surgical treatment of the overall 5-year survival rate was 62.2%.
Introduction. Results of the systemic chemotherapy in the peritoneum canceromatosis are unsatisfactory because of poor penetration of anticancer drugs in serous cavities due to the presence ofperitoneal-plasma barrier. One of the possible ways to enhance the action cytostatic agents is the use of chemotherapy and hyperthermia, which, according to some data, has an own cytotoxic effect. The purpose of the study. The study of the effect ofdifferent modes of hyperthermia on the physiological activity of transplantable lines of tumor and non-transformed cells. Results. Analysis of the impact of hyperthermia on the physiological activity of transplantable lines of tumor and the non-transformed cells in vitro and in vivo studies demonstrated that along with the gain in the level and time of the temperature exposure as the degree of damage as tumor cell mortality rate increases. In this study the most effective treatment was as follows: the temperature is above 45°C with the exposure of more than 2 hours, which is difficult to achieve in practice due to the limited tolerance of healthy tissues. Conclusion. With the use of hyperthermia in monoregimen it is not possible to achieve effective levels of the temperature impact, which could hardly have a significant inhibitory effect on tumor cells.
Aim. Evaluation of prognostic role of estrogen receptors a (ERa) expression level at patients with non-small cell lung cancer (NSLC) after surgical treatment. Methods and materials. 115 clinical cases of patients who underwent treatment in N.N.Blokhin Russian Cancer Research Center fr om 2009 to 2016 were studied. There were 95 males and 20 females. All patients had NSLC confirmed by histological analysis and followed-up for long term results. Results. There was no statistical evidence that the level of estrogen a expression in tumor cells has an impact on relapse free survival among men with both adenocarcinoma and squamous cell carcinoma of the lung. Similar results were obtained for women group. Also, no correlations between overall survival and the level of estrogen a expression were noticed among men and women. Thus ERa can’t be used as a predictor marker for patients with NSLC. Conclusion. The level of ERa expression in tumor cells among male patients does not influence on disease prognosis regardless stage of the disease and tumor morphology and can’t be used as a prognostic factor. The impact of the ERa expression level in tumor cells among female patients on disease prognosis is questionable.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
