IMMUNOPHENOTYPIC CHARACTERISTICS OF INFLAMMATORY BREAST CANCER

The investigation enrolled 31 patients with inflammatory breast cancer (IBC) treated at the N. N. Blokhin Cancer Research Center from 2006 to 2008. IBC is diagnosed on the basis of signs of rapid progression, such as localized or generalized breast induration, red- ness and edema. IBC accounts for less than 5% of all diagnosed breast cancers and is the most lethal form of primary breast cancer. We studied tumor markers of the immunophenotype of IBC and levels and subpopulations of immunocompetent tumor-infiltrating cells. We found that expression of HLA-DR is in negative correlation with MUC-1 expression and lymphoid cells tumor infiltration is asso- ciated with the increase in T-cell subpopulations

ГЕПАТОЦЕЛЛЮЛЯРНЫЙ РАК ПРОМЕЖУТОЧНОЙ СТАДИИ. BCLC B – ОФИЦИАЛЬНЫЕ РЕКОМЕНДАЦИИ, КАК СТРАТЕГИЯ БАЗИСНОГО ЛЕЧЕНИЯ И ТОЧКА ОТСЧЕТА В ОЦЕНКЕ ЭФФЕКТИВНОСТИ НОВЫХ ПОДХОДОВ

Представлен анализ Барселонской клинической классификации (BCLC) гепатоцеллюлярного рака (ГЦР). Подробно освещены лечебные рекомендации, предлагаемые BCLC для промежуточной стадии, рассмотрены современные мировые тенденции по внедрению эффективных  лечебных стратегий. Проведен анализ клинической гетерогенности промежуточной стадии (BCLC В), проблем диагностики и лечения. Подчеркнута важность стандартизованного алгоритма обследования для точной диагностики  промежуточной  стадии ГЦР. Рассмотрены перспективы оптимизации лечебных стратегий при BCLC В: поиск  и создание возможностей для радикального оперативного лечения, а также рациональное использование консервативных методов – химиоэмболизации и системной терапии – в лечении неоперабельных больных ГЦР

Phase 3 KEYNOTE-042 Study: Pembrolizumab vs Platinum-Based Chemotherapy as 1l Therapy for Advanced NSCLC with a PD-L1 TPS ≥1%

First-line (1L) therapy with pembrolizumab in patients with metastatic NSCLC without targetable aberrations and programmed death ligand 1 (PD-L1) tumor proportion score (TPS) ≥50% significantly improved the primary endpoint of PFS, and OS (secondary endpoint) compared to chemotherapy in the KEYNOTE-024 study. In KEYNOTE-042 (NCT02220894), we evaluated pembrolizumab vs chemotherapy at the lower PD-L1 TPS of ≥1%

Experience of treatment of a patient with non-small cell lung cancer with met exon 14 skipping

Personalized therapy is starting to play an increasing role in modern approaches to the treatment of oncological diseases. The previously existing uniform standard for each malignant disease is expanded with new options and treatment possibilities, depending on each specific clinical situation. That increases the  effectiveness of  therapy and helps to control the  disease. A  separate niche in the individual approach to anti-tumor treatment is occupied by targeted therapy of malignancies. There are a lot of mutations that can lead to the emergence of malignant neoplasms. So of all that multitude of choices the individual approach to a patient helps to select the mutations that are most likely to be found in a given patient. The research in the area of the c-MET mutation has allowed it to occupy its niche as a therapeutic target. The identification of this mutation is not included in the routine set of analyses performed for a patient with diagnosed lung adenocarcinoma. But expanding the panel of molecular testing would increase the detectability of this mutation and, as a result, improve the quality of treatment for this category of patients. This clinical case describes the experience of treatment of an elderly patient with lung adenocarcinoma, in whose tumor tissue a MET mutation was detected

Практические аспекты современной противоопухолевой терапии местнораспространенного и метастатического билиарного рака

Although gallbladder and biliary tract cancer is a rather rare group of diseases, it is among the pressing issues of modern oncology. Adequate surgery is the only curative method that can give a chance for recovery for a small proportion of patients at early stages of the disease. The scope of opportunities of drug therapy in biliary tract cancer is limited by the low effectiveness of the few currently available cytostatics. The addition of chemotherapy has little effect on the long-term outcome of surgery and other local interventions. Apparently, future treatments for these patients should be developed based on studies of targeted therapy and its combination with standard cytotoxic therapy, as well as possible targeting of anticancer immune response, which necessitates a search for immunotherapy efficacy predictors. The objective of this article is to consider the practical potential of drug therapy for biliary tract cancer and to review the studies that looked into molecular genetic targets and effective combinations of existing drugs, analyzing possible practical applications of the study results.Несмотря на то, что рак желчного пузыря и желчных протоков является достаточно редким заболеванием, он представляет собой значимую проблему современной онкологии. Хирургическое лечение в адекватном объеме — единственный метод, способный дать шанс на выздоровление для небольшой части больных с ранними стадиями заболевания. Возможности лекарственной терапии билиарного рака ограничены невысокой эффективностью узкого перечня используемых цитостатиков. Добавление химиотерапии мало отражается на отдаленных результатах хирургии и других методов локального воздействия. Перспективы в лечении этой группы больных видятся в области изучения таргетной терапии и ее комбинации со стандартной цитотоксической терапией, а также в возможном влиянии на иммунный противоопухолевый ответ, что обусловливает поиск предикторов эффективности иммунотерапии. Целью этого обзора является рассмотрение практических возможностей лекарственной терапии билиарного рака, освещение исследований, направленных на поиск молекулярно-генетических мишеней и эффективных комбинаций уже существующих препаратов и возможное применение полученных результатов в практике

Prognostic value of the proportion of the sclerosing component in fibrolamellar liver carcinoma

Introduction. Fibrolamellar hepatocellular carcinoma (FLC), which develops most often in the younger population. In FLC, variable histoarchitectonics are noted, possibly the presence of a sclerosing component, foci of necrosis and dystrophy of tumor cells.Objective. Assessment of the influence of the proportion of the sclerosing component in fibrolamellar carcinoma (FLC) of the liver on the course and prognosis of the disease. Determination of the relationship between the proportion of the sclerosing component in the tumor and the frequency of microvascular invasion.Materials and methods. A retrospective study included 34 patients with a diagnosis of FLC, who underwent radical surgical treatment at the first stage. A histological assessment of the proportion (%) of the sclerosing component in FLC was made. The effect of  the  proportion of  the  sclerosing component on overall (OS) and relapse-free (DFS) survival was assessed. The  analysis of the relationship between the proportion of the sclerosing component in the tumor and the frequency of microvascular invasion was carried out.Results. Significantly worse RFS was achieved in the groups of patients with a sclerosing component in FLC > 5% than in the group of patients with a sclerosing component in FLC ≤ 5% (p = 0.0010; p = 0.024; log – rank test). Median DDS in group 1 is 107 (95% CI, 22–192) months; at 2 – 11 (95% CI, 8–14) months; in 3 – 21 (95% CI, 8–33). The frequency of histologically confirmed microvascular invasion in the compared groups was 29, 74, 87.5%, respectively. OS was significantly worse in 2 groups (27 patients in total) with a sclerosing component in FLC > 5% than in the group of patients with a sclerosing component in FLC ≤ 5%. Median OS in group 1 120 (95% CI, 60–180) months; at 2 – 41 (95% CI, 15–92) months; in 3 – 69 (95% CI, 35–103). A direct relationship was found between an increase in the proportion of the sclerosing component in a tumor and an increase in the frequency of microvascular invasion.Conclusions. We can assume that the severity of the sclerosing component in the FLK tumor can serve as an effective morphological marker of a less favorable prognosis for this HCC subtype and correlate with the frequency of microvascular invasion
