Neoplasms. Tumors. Oncology. Including cancer and carcinogens ,RC254-282 - Abstract
За последние 20 лет заболеваемость неходжкинскими лимфомами (НХЛ) увеличилась более чем на 50% и по темпу роста опережает лимфому Ходжкина (И.В.Поддубная, Л.Г.Бабичева, 2004).По данным разных исследователей отмечено увеличение встречаемости экстранодальных НХЛ: они составляют от 24 до 48% всех НХЛ (И.В.Поддубная, Ю.Н.Балакирева, 2004). НХЛ орбиты, глаза и его придаточного аппарата, по данным G.Canellos и J.Lister, составляют 4,1% от всех экстранодальных лимфом.В последние годы в клинической онкогематологии большое значение придают прогнозу для жизни больных НХЛ. Для определения прогноза в таких случаях был разработан Международный прогностический индекс (МПИ).

гастроинтестинальные опухоли ,гливек ,Neoplasms. Tumors. Oncology. Including cancer and carcinogens ,RC254-282 - Abstract
Непроходящий интерес онкологов обоснованно вызывают гастроинтестинальные опухоли (GIST). С момента первого описания Кахалом в 1889 г. фибробластоподобных клеток, обеспечивающих связь между интрамуральными нервными сплетениями и гладкомышечными клетками кишечника, прошло более 100 лет, но лишь в последнее десятилетие эти опухоли стали предметом пристального внимания. Широкое внедрение иммунологического метода позволило установить иммунофенотип опухоли, а доказанная высокая (∼95%) экспрессия опухолевыми клетками рецептора KIT положила начало использованию целенаправленной терапии – применению препарата Гливек.

Neoplasms. Tumors. Oncology. Including cancer and carcinogens ,RC254-282 - Abstract
Успехи в терапии онкологических и гематологических заболеваний очевидны, и это требует использования профессионалами всего арсенала лекарственной помощи. Переносимость и безопасность химиотерапии – основное требование современной клинической онкологии. Хорошо известно, что рациональное использование колониестимулирующих факторов значительно расширяет терапевтические возможности. Накоплен большой опыт по профилактике и коррекции нейтропении. Наступило время расширения использования в онкологической практике эритропоэзстимулирующих препаратов (ЭСП). Группа ведущих онкологов и гематологов России обсудила различные аспекты использования ЭСП в ходе рабочих совещаний и итогового экспертного совещания, которое состоялось 3 ноября 2007 г. в Москве. Итогом этой работы стало создание и подписание Резолюции по использованию ЭСП в онкологии. Обоснованием создания такого документа является острая необходимость совершенствования оказания дорогостоящей (высокотехнологической) медицинской помощи онкологическим больным с последующим оправданным изменением стандартов. Публикуемая Резолюция может служить обоснованным руководством к использованию ЭСП. Создатели и разработчики Резолюции гарантируют своевременное внесение изменений при появлении в мировой практике новых данных.

Возможности лечения рака молочной железы (РМЖ) даже при наличии отдаленных метастазов существенно возрастают за счет расширения арсеналапрепаратов - химиотерапевтических, гормональных, а также благодаря появлению и внедрению в лечебный процесс целой группы неспецифических противоопухолевых средств - бисфосфонатов, которые способны оказывать значительное влияние на течение метастатического процесса в костной системе. Применение бисфосфонатов возможно также при эндокринной терапии РМЖ, так как они могут способствовать профилактике снижения костной плотности или повышению ее при развившейся остеопении.

Neoplasms. Tumors. Oncology. Including cancer and carcinogens ,RC254-282 - Abstract
Диффузная крупноклеточная В-клеточная лимфома ( ДККЛ ) - наиболее часто встречающийся вариант неходжкинских лимфом ( НХЛ ) выской степени злокачественности, неоднородный по морфологическим характеристикам, клиническим проявлениям и чувствительности к терапии. Режим CHOP (циклофосфамид, доксорубицин, винкристин, преднизолон) является "золотым стандартом" лечения больных ДККЛ, но полная ремиссия достигается только в 50 - 55% случаев. Добавление мабтеры к стандартной химиотерапии CHOP существенно снизило риск неудачи терапии и смерти (уровни риска 0,58 и 0,64 соответственно). Эти результаты были получены без существенного увеличения клинически значимых токсических проявлений.

Neoplasms. Tumors. Oncology. Including cancer and carcinogens ,RC254-282 - Abstract
В течение последнего десятилетия в РС (Я) происходят изменения большинства показателей состояния онкологической помощи. Эти тенденции распространяются и на злокачественные новообразования женских половых органов. Анализ данных о состоянии онкогинекологической помощи в РС(Я) с 1991 по 2001 г. показал, что при раке яичников на 2001 г. самая низкая доля морфологически верифицированных диагнозов - 82,6%. Для сравнения этот показатель при злокачественных новообразованиях шейки матки составил 89,3%, тела матки - 100%. Негативные динамические изменения показателя морфологической верифиции диагнозов свидетельствуют о снижении качества диагностики, что в первую очередь связано с ограничением диагностических возможностей, низкой онкологической настороженностью врачей общей лечебной сети.Изложенные данные свидетельствуют о том, что в онкогинекологической службе республики существует множество нерешенных практических задач. Одной из самых приоритетных является разработка и внедрение в широкую практику комплексной программы скрининга злокачественных новообразований женской репродуктивной системы.

В настоящее время рак молочной железы ( Р МЖ ) в России занимает первое место в структуре заболеваемости и смертности от злокачественных новообразований среди женщин. Важное место в лечении больных РМЖ занимает химиотерапия. Наилучшие результаты в лечении распространенного РМЖ достигаются при использовании комбинации антрациклиновых антибиотиков с таксанами.Кафедра онкологии Российской медицинской академии последипломного образования работает в тесном контакте с онкологическими диспансерами Российской Федерации, в большинстве которых химиотерапевтическая служба отвечает всем современным требованиям. Анализ использования схемы доцетаксел/доксорубицин в течение 3 лет в Краснодарском городском онкологическом диспансере) показал реальную возможность экономии финансовых средств. Все это послужил о основанием для разработки по инициативе кафедры онкологии РМАПО Региональной программы лечения местно-распространенного и метастатического РМЖ с использованием режима доцетаксел /доксорубицин.

Мабтера (rituximab) - принципиально новый противоопухолевый препарат, доказавший свою эффективность и безопасность в лечении неходжкинских лимфом (НХЛ) низкой степени злокачественности.Успешное лечение НХЛ низкой степени злокачественности на всех этапах болезни и сведения о синергизме с антрациклинами, алкилатами и глюкокортикоидами послужило основанием для попытки расширения показаний к применению мабтеры. Оказалось, что мабтера в монорежиме при НХЛ высокой степени злокачественности эффективна у 30% больных. Добавление мабтеры к схеме CHOP - схема R-СНОР была апробирована у нелеченных больных фолликулярной НХЛ- выявлена высокая результативность - 98%. За период с начала 2000 г. до середины 2001 г. в отделении химиотерапии гемобластозов и дневном стационаре РОНЦ им. Н.Н. Блохина РАМН режим R-CHOP был использован у 16 первичных больных B-клеточными НХЛ высокой и промежуточной степенями злокачественности.Полученные предварительные результаты свидетельствуют о высокой эффективности и удовлетворительной переносимости режима R-CHOP у больных НХЛ высокой степени злокачественности.

Neoplasms. Tumors. Oncology. Including cancer and carcinogens ,RC254-282 - Abstract
В настоящее время сохраняется тенденция к увеличению заболеваемости злокачественными новообразованиями.Многие вопросы при выборе терапевтической тактики при лимфомах все еще далеки от разрешения. Особенно это относится к пациентам пожилого и старческого возраста ввиду значительно большей выраженности у них токсических эффектов стандартной химиотерапии и менее благоприятным прогнозом по сравнению с более молодыми больными. Отсюда особое внимание привлекает принципиально новый противоопухолевый препарат «Мабтера».В рамках разработки новых методов лечения пожилых больных НХЛ нами было выполнено исследование по изучению эффективности и безопасности мабтеры для терапии рецидивов и рефрактерных форм НХЛ низкой степени злокачественности. Исследование было проведено на базе трех центров РОНЦ им. Н.Н. Блохина РАМН (Москва), Российского научного центра рентгенорадиологии МЗ РФ (Москва), НИИ онкологии им. Н.Н. Петрова (Санкт-Петербург).Анализ эффективности и токсичности монотерапии мабтерой у пожилых больных позволяет сделать следующие выводы - 1. Лечение эффективно, безопасно, легко осуществимо и может широко применяться в амбулаторной практике. 2. Мабтера является препаратом выбора для лечения пожилых пациентов с рецидивами НХЛ низкой степени злокачественнсти, отнесенных по МПИ к группе благоприятного прогноза. 3. Мабтера высокоэффективна при различных экстранодальных проявлениях НХЛ низкой степени злокачественности. 4. Необходимы дальнейшие исследования с целью оптимизации показаний для применения препарата у пожилых больных.

Роль эндокринной терапии при раке молочной железы (РМЖ) трудно переоценить. В последние годы ее новые возможности были реализованы при появлении ингибиторов ароматазы. Именно это объясняет интенсивность исследований в этой области с углубленным изучением ингибиторов , позже - инактиваторов этого фермента. Приведенные данные свидетельствуют о том, что арсенал эндокринной терапии пополнился еще одним перспективным препаратом, широкое внедрение которого в практику российских онкологов окажет положительное влияние на судьбу женщин, страдающих РМЖ.

The retrospective study of clinical data, risk factors, and results of treatment of a large group of patients with primary systemic anaplastic large-cell lymphoma (ALCL) (n = 42) with the Т-/О phenotype is presented. Primary systemic ALCL occurred in young persons aged less than 30 years. A group of patients with its poor course (with complete remission (CR) being achieved) showed a trend for the prevalence of the signs that were a part of the standard (International Prognostic Index — IPI) factors and ones of poor prognosis, which were additionally analyzed by the authors. Significant differences in a group of patients with a good prognosis (with CR being achieved) were obtained only in the following indices: ALK protein expression (substantiating the further division and study of a homogenous group of patients), the stage of the disease, evaluation of the patients’ general condition by the ECOG scale, and the presence of B-symptoms.According to the data available in the literature, ALK-positive ALCL has a better prognosis than ALK-negative ALCL. The results given in this communication additionally confirm and extend these observations. There is evidence that, by using the IPI and the baseline prevalence of the disease, one may predict an outcome in the homogenous group of patients without CR being achieved after first-line therapy. Analysis of the findings has established no clinical risk factors associated with the baseline site of a tumor process, which influence long-term results, but this matter should be studied in further prospective investigations, by keeping in mind the location zones characteristic of ALCL.

Background. The role of neoadjuvant chemotherapy (NACT) in luminal HER2-negative breast cancer (BC) remains highly controversial due to the lack of reliable predictors of drug therapy efficacy.Objective: to evaluate the effectiveness of NACT in patients with aggressive luminal HER2-negative BC and to compare modern systems for assessing the pathomorphological response.Materials and methods. The tumor response to NACT regimens was assessed in 64 patients with aggressive luminal HER2-negative BC stage II–III. The median age of women was 46.5 years (range 31–76 years), 76.6 % had primary operable stages (cT1–3N0–1), locally advanced BC (cT4, cN2–3) – 23.4 % patients. The characteristics of BC were as follows: invasive ductal carcinoma (76.6 %), grade G2 and G3–54.7 % and 45.3 %, Ki-67 ranged from 20 % to 98 %, median 45 %. The ER expression level was low (1–10 %, ERlow) in 12.5 % and was more than 10 % in 87.5 % of cases. HER2 status corresponded to 0, 1+ and 2+ in the absence of gene amplification – in 50.0 %, 35.9 % and 14.1 % of patients, respectively. The rate of TILs 20 % was in 71.4 %, 10.7 % and 17.9 % of cases. After NACT with the inclusion of anthracyclines and taxanes ± platinum combinations (in BRCA mutated status), the patients underwent radical surgery (mastectomy or breast-conserving surgery) with an assessment of the pathological response.Results. 15.6 % of patients had a complete pathomorphological response (pCR) to treatment, which corresponded to the RCB-0 class and the pathomorphological stage ypT0N0. Residual tumor load with incomplete response was very significant – class RCB-I was noted in only 7.8 %, and RCB-II and RCB-III – in 39.1 % and 37.5 %, respectively. An increase in the size of the residual tumor and the number of affected lymph nodes were associated with an increase in the RCB class. Predictors of pCR achievement in luminal HER2-negative cancer were: grade G3, rare histological forms of BC (medullary, metaplastic), rate of TILs ≥30 %, low ER expression, and HER2 0 status.Conclusion. Assessment of Ki-67, tumor grade, ER and HER2 rate, and TILs before starting NACT will help identify a group of high sensitivity to chemotherapy and optimize the treatment strategy in aggressive luminal HER2-negative BC.

HER2-positive breast cancer is a unique subtype of the disease, not only in terms of aggressive biology, but also in terms of treatment options. Over the past 15 years, the strategy for treating early HER2-positive breast cancer has undergone a real evolution – from the absence of anti-HER2 therapy to the sequential introduction of adjuvant, neoadjuvant and post neoadjuvant approaches. This review describes key studies of systemic therapy for HER2-positive breast cancer stage I–III, which made it possible to establish clear priorities in the sequence of surgical and systemic steps, identify high risk groups which need of escalation of treatment, and determine the optimal anti-HER2 therapy for each steps, as well as de-escalation of stage I treatment without losing its effectiveness. The news from the latest cancer conferences (SABCS, ESMO, ASCO) on the impact of various biological markers on the effectiveness of anti-HER2 agents is presented. A clear concept of modern treatment of early HER2-positive breast cancer has been formed, allowing individualized approaches, and achieving better results of the therapy this aggressive biological subtype.

Monoclonal gammopathy of renal significance (MGRS) is a new nosology in modern nephrology and oncohematology. MGRS is defined as kidney injury due to nephrotoxic monoclonal immunoglobulin produced by the B-cell line clone which does not reach the hematological criteria for specific treatment initiation. Monoclonal proteins pathological effects on kidney parenchyma result in irreversible decline of kidney function till the end stage renal disease that in line with the position of International Consensus of hematologists and nephrologists determinates critical necessity for clone specific treatment in patients with MGRS despite the absence of hematological indications for treatment initiation. Main challenge of MGRS in Russian Federation is an inaccessibility of an in-time diagnostic and appropriate treatment for the great majority of patients due to the following reasons: 1) limited knowledge about the MGRS among hematologists and nephrologists; 2) lack of necessary diagnostic resources in most health-care facilities; 3) lack of approved clinical recommendations and medical economic standards for treatment of this pathological entity. Consensus document comprises the opinion of experts leading nephrologists and hematologists of Russian Federation on the problem of MGRS including the incoherence in nosology classification, diagnostics approach and rationale for clone specific treatment. Consensus document is based on conclusions and agreements reached during the conference of leading nephrologists and hematologists of Russia which was held in the framework of symposia Plasma cell dyscrasias and lymphoproliferative diseases: modern approaches to therapy, 1516 of March 2019, Pavlov First Saint Petersburg State Medical University. The present Consensus is intended to define the principal practical steps to resolve the problem of MGRS in Russian Federation that are summarized as final clauses.

The EQUILIBRIUM post-registration multicenter study included 1000 patients aged 21 to 91 years old with a verified diagnosis of B-cell non-Hodgkin’s lymphoma, or chronic lymphocytic leukemia, who received at least 4 cycles of rituximab-containing therapy with Acellbia®. The group of aggressive non-Hodgkin’s lymphomas (aNHL), which is the subject of this article, included 295 patients with a median age of 55.9 years: diffuse B-large cell lymphoma – 87 %, primary mediastinal lymphoma – 11 %, Burkitt’s lymphoma – 1 %. Group characterized by the presence of aggressive clinical signs reflecting the poor prognosis: in the majority of patients, generalized stages were diagnosed (61 %), in half of the cases (50.2 %), extranodal localization of tumor foci was detected (in 32.4 % of patients there were 2 or more). The overwhelming majority of patients (84.5 %) received adequate treatment complying with national and international recommendations (R-CHOP, R-CHOEP and R-EPOCH, high-intensity NHL-BFM-R, R-HyperCVAD and R-MACOP-B regimes). The use of R-CVP, FCR, RB, Chl-R, R-monotherapy treatment programs (which received 15.5 % of patients) was considered inadequate for this category of patients.Results. According to the results of the final assessment, high therapy efficacy was established: the overall response exceeded 90 %, complete remission was achieved in most patients with aNHL (68.5 %), partial remission – in every 5th patient (21.8 %). With a median follow-up of 15 months, 16 (5.42 %) deaths and 34 (11.53 %) events were registered. Median of event-free survival and overall survival have not been achieved. Statistically significant differences depending on first-line therapy efficacy were found in overall survival (p = 0.00000) and eventfree survival (p = 0.00000), once again confirming that the main goal of aNHL treatment is to achieve complete remission.Conclusion. Available and compliant with national clinical guidelines treatment of aNHL patients with Russian bioanalogue of anti-CD20 monoclonal antibodies (Acellbia®) demonstrates high immediate efficacy and acceptable long-term results, comparable to a retrospective analysis of previous clinical studies of the original drug rituximab.

Backgraund. Currently, immunotherapy is firmly established in the standard of cancer treatment. The basis for the appointment of immunotherapy are immunological tumor markers, which include lymphoid infiltration, a detailed study of which has received increasing attention in the last decade. An undoubted interest is the study of lymphoid infiltration, not only depending on the morpho-clinical parameters of breast cancer (BC), but also on the immune system of the bone marrow.Aim. To evaluate the infiltration of the primary tumor by lymphocytes depending on the morpho-clinical characteristics of BC and immune responses in the bone marrow.Materials and methods. This study included 125 patients with BC who received treatment at the “N.N. Blokhin National Medical Research Center of Oncology” of the Ministry of Health of Russia. Tumor stage II was prevailed, а moderate degree of differentiation (G2) was more often noted. The luminal BC – 67 %, non-luminal – 33 %. Immunophenotyping of the primary tumor: cryostat sections, ZEISS Axioscope luminescent microscope (Zeiss AG, Germany). CD45+, CD38+, T- and B-cell infiltration were assessed. Bone marrow: CD3+, CD4+, CD8+, CD19+, CD16+, CD56+ lymphocytes and their subpopulations were studied (FACSCanto II flow cytometer, Kaluza Analysis v2.1 program (Beckman Coulter, USA)).Results. CD45+ infiltration was noted in 50.5 % of cases (severe in 30 %, moderate – 26.4 %). CD8+ cells significantly infiltrated the tumor in 21.4 % of cases. CD38+ infiltration was observed in 40 %. In the non-luminal BC, severe CD45 infiltration was observed more frequently than in the luminal (33 % vs 26 %). CD38+ infiltration is expressed in non-luminal BC (p = 0.016). CD45+ infiltration was positively correlated with earlier stages (p = 0.071) more pronounced in infiltrative ductal BC, than in lobular BC: 59.2 % vs 20 % (p = 0.05). The content of CD45RO+cells in bone marrow in the luminal BC is higher than in the non-luminal: 37.3 ± 2.3 % vs 28 ± 2.8 % (p = 0.04). The number of CD19+CD38+ cells, on the contrary, is less: 24.2 ± 2 % vs 34.8 ± 6 % (p = 0.041). Tumor-infiltrating lymphocytes highly correlated with bone marrow lymphoid populations: CD38+ cells with NK-bone marrow cells; CD4+ cells with the B-precursors; CD8+cells with the B1-lymphocytes.Conclusion. Lymphoid infiltration of BC is associated with stage, tumor size, histological type and biological subtype. Intratumoral populations CD38+, CD4+, CD3+, CD8+ cells are in a negative correlation with bone marrow lymphoid populations.

Relevance. Endocrine therapy is the standard treatment for women with ER-positive breast cancer. The clinical response to Tamoxifen is variable. Approximately 30 % of patients with breast cancer will have a recurrence of the disease within 15 years after treatment, despite ongoing endocrine therapy. This article presents the results of a prospective pharmacogenetic cohort study. The study was conducted in 2018–2019. Aim. To analyze adverse drug reactions to Tamoxifen in the adjuvant regimen in breast cancer patients in relation to the carriage of genetic polymorphisms of genes encoding cytochrome P450 enzymes and drug transporter proteins and to build predictive models based on them. A comparative analysis of the relationship between genetic and non-genetic determinants with adverse events on tamoxifen therapy allowed us to build predictive models of their development. Materials and Methods. The study involved 120 women with pre- and postmenopausal breast cancer who underwent genetic testing for CYP and Pg enzyme gene polymorphisms. Entry criteria: a histologically confirmed diagnosis of breast cancer, taking Tamoxifen at the recommended doses, establishing a diagnosis not earlier than 2007, and obtaining informed voluntary consent to participate in the study. Allelic variants were determined using real-time polymerase chain reaction in the Research Institute for Molecular and Personalized Medicine of the Russian Medical Academy of Continuous Professional Education of the Ministry of Healthcare of the Russian Federation. Results. An associative analysis showed their association with the development of adverse drug reactions (ADR) to Tamoxifen, indicating the clinical significance of different genetic polymorphisms of CYP2D6, CYP3A5, CYP2C9 and ABCB1. The complex associative analysis performed using mathematical modeling made it possible to build predictive risk models for the development of such ADR, such as hot flashes, dyspepsia, bone pain, and asthenia. The resulting regression models were statistically significant (p < 0,001) and demonstrated high diagnostic efficiency. This allows them to be implemented in clinical practice. Conclusion. Thus, models that include both genetic and non-genetic determinants of response may further improve the prediction of individual response to tamoxifen

Background. Immunotropic drugs are widely used in the modern strategy of cancer treatment. Importance is given to immunological markers of the tumor, which determine the prognosis of the disease, the effectiveness of treatment. Therefore, the study of their expression is one of the leading scientific directions. Of particular interest is the study of monomorphic HLA determinants, transferrin receptor 1 (TfR1), depending on its biological subtype of breast cancer.Aim. To evaluate the frequency of expression of HLA class I, II, TfR1 molecules by breast cancer cells and determine their relationship with the molecular biological subtype of the tumor.Materials and methods. This study included 120 patients with breast cancer who received treatment at the N.N. Blokhin National Medical Research Center of Oncology, Ministry of Health of Russia. Tumor stages II and III prevailed: 56.7 % and 33.4 %, respectively. A moderate degree of differentiation (G2) was more often noted. The luminal subtype was 58.3 % (n = 70), non-luminal – in 41.7 % (n = 50). Immunophenotyping of the primary tumor was performed by immunofluorescence on cryostat sections. The reaction was evaluated using a ZEISS Axioscope 5 luminescent microscope (Zeiss AG, Germany). The frequency of expression of HLA class I and II molecules were studied depending on the clinical and morphological characteristics of breast cancer. The frequency of expression of HLA class I, HLA-DR, TfR1, molecules, toumor infiltration of СD45+, CD38+, depending on the molecular subtype of breast cancer was studied.Results. It was found that the frequency of expression of monomorphic determinants of the HLA class I in luminal and non-luminal subtypes of breast cancer was comparable; HLA-DR was expressed significantly more often in the luminal subtype of breast cancer: 37.3 % and 18.0 %, respectively, p = 0.022. The frequency of TfR1 expression was significantly higher in the luminal subtype of cancer compared to non-luminal, p = 0.014. Predominantly monomorphic type of reaction was observed: in 76.5 % (n = 39) of cases. The mosaic type of the TfR1 reaction was noted in 7.8 % of the samples. TfR1 monomorphic expression was detected in 50.0 % (n = 30) of cases in non-luminal cancer, the mosaic expression – in 20.0 % (n = 12) of cases. A pronounced degree of lymphoid infiltration, in particular plasmacytic, was established in non-luminal subtype of breast cancer: 70.7 % (n = 29) and 35.0 % (n = 14), respectively, p = 0.001. An association was noted between the expression of HLA I class molecules and the severity of general leukocyte infiltration, p = 0.007.Conclusion. The frequency of expression of HLA class I monomorphic determinants did not differ in molecular subtypes of breast cancer. The expression of the HLA class II molecule was significantly more frequently observed in the luminal subtype of breast cancer. The expression of HLA class I monomorphic determinants is associated with the degree of lymphoid infiltration of the tumor. In the non-luminal subtype, plasmacytic infiltration is more pronounced. The expression of transferrin receptors is significantly more pronounced in the luminal subtype.

Background. Molecules of the major histocompatibility complex in cancer are currently being widely studied, and their clinical significance is still the subject of controversy. It is reported that they might have an important predictive value in the effectiveness of immunotherapy. The study of the expression HLA molecules status in breast cancer provides a deeper understanding of the biological properties of the tumor, in particular to identify the features of its immunological phenotype, which may further influence on breast cancer therapy.Aim. To evaluate the frequency of HLA-immunophenotypes in breast cancer and their relationship with the clinical and morphological features of the primary tumor.Materials and methods. This study included 82 patients with breast cancer who received treatment at the N.N. Blokhin National Medical Research Center of Oncology, Ministry of Health of Russia. Immunophenotyping of the primary tumor was performed by immunofluorescence on cryostat sections. The reaction was evaluated using a ZEISS Axioscope 5 luminescent microscope (Zeiss AG, Germany). The study was dominated by patients with stage IIB 54 %, stage IIA was detected in 5 % of cases, IIIA – in 12 % of cases, IIIB – in 21 % of cases, IIIC – 8 %. Infiltrative ductal breast cancer was diagnosed in 67 % of patients (n = 55), infiltrative-lobular – in 22 % of cases (n = 18), other types – in 11 % (n = 9). The frequency of immunophenotypes was studied depending on the clinical and morphological characteristics of breast cancer.Results. It was found that in the group as a whole, the HLA-binegative immunophenotype of breast cancer was predominant. It dominated at stage T4 compared to the HLA-I+/HLA-DR+ phenotype (100 and 0 %), p = 0.042. At the same time, it should be noted that in T4 primary tumor the HLA-I+/HLA-DR– immunophenotype was also observed. The relationship this immunophenotype was noted with the stage: frequency at stage IIIA was higher than the HLA-I+/HLA-DR+ phenotype, 60 and 40 %, p = 0.01. Both HLA-DR-negative immunophenotypes were characterized by a high incidence of lymph node involvement and the absence of estrogen receptor expression. 80 % of receptor-negative tumors were noted in HLA-binegative immunophenotype compared to phenotype HLA-I+/HLA-DR+, p = 0.022; the similar data were obtained for the HLA-I+/HLA-DR– immunophenotype (p = 0.037).Conclusion. HLA immunophenotypes analysis of breast cancer revealed the HLA-binegative immunophenotype of breast cancer was predominant. The second most common immunophenotype was the absence of expression of HLA-DR molecules. The association of HLA-immunophenotypes with the stage of the tumor process, the size of the primary tumor, and the expression status of estrogen receptors was revealed.

The study included patients with noninvasive cancer and stage T1a-b-cN0M0 invasive breast cancer who were treated between 1985 to 2009 in Russia (at the N.N. Blokhin Russian Cancer Research Center and at the Clinic of the Russian Medical Academy of Postgraduate Training, 1036 patients), and in the Netherlands (LUMC, 560 patients, National Cancer Register, 22196 patients). The comparative analysis of surgery types between countries was carried out. The frequency of organ-preserving surgeries for early breast cancer in Russian and in the Netherlands was identical (53.7 % and 52.5 %). The percentage of organ-preserving surgeries over the past 20 years in Russia was not significantly changed, whereas the decrease in the rate of organ-preserving treatment from 56.2 % to 41.2 % was observed in the Netherlands.This is most likely due to an increase in the number of patients in postmenopause (>60 years) from 53.1 % to 63.8 %. The main type of organ-preserving treatment in Russia is radical resection of the breast. In the Netherlands, lumpectomy with sentinel lymph node biopsy or axillary lymphodissection is the most common form of breast-conserving surgery today.

Introduction. An important aspect of cancer treatment today is the concept of immuno-targeted therapy, which requires a deep understanding of the characteristics of immune reactions in the body of a cancer patient. Bone marrow is the central organ of immunopoiesis, therefore, along with the study of tumor characteristics, attention is paid to the bone marrow. The study of the cellular composition of the bone marrow in some types of cancer revealed a number of features of hematopoiesis, which requires further deeper analysis.Purpose. To study the parameters of hematopoiesis in patients with primary and recurrent ovarian cancer.Materials and methods. The paper presents data from 68 patients with a verified diagnosis of primary (n = 43) and recurrent (n = 25) ovarian cancer. The study was dominated by serous adenocarcinoma of high grade. Stage I was established in 13.2 % of cases, II – in 5.9 %, III – in 60.3 %, IV – in 20.6 %. The bone marrow was harvested by puncture of the posterior iliac spine (spina iliaca posterior superior). Parameter assessment and myelogram calculation were performed by two physicians, morphologists. The content of myelokaryocytes, indicators of granulocyte, erythroid lineage, the content of lymphocytes, monocytes were analyzed, and myelogram indices were assessed. In all patients microscopy of bone marrow samples excluded metastatic lesions. Statistical data processing was performed using the SPSS Statistics v. 21 package.Results. The analysis of bone marrow samples from patients with ovarian cancer revealed differences with the norm for both primary and recurrent ovarian cancer. Most punctates were normocellular, but average myelokaryocyte count in both groups was below normal. With recurrent ovarian cancer, a reduced content of promyelocytes and metamyelocytes was noted, whereas with primary cancer, all young forms of neutrophils was below normal. An increase in segmented neutrophils without a change in the percentage of cells of the granulocytic lineage was observed in primary ovarian cancer, and in one third of the samples of bone marrow an increased number lymphocytes and monocytes were noted. With recurrent ovarian cancer lymphocytes were increased in 2/3 of samples, monocyte – in 48 %. A change in the proportion of cells of the erythroid lineage was observed in both recurrent and primary cancers: depletion of the pool of basophilic normoblasts and polychromatophils with an unchanged number of erythrokaryocytes, an increase in oxyphilic forms were noted.Conclusion. The revealed changes in hematopoiesis in ovarian cancer reflect the aggressive course of high-grade tumors, which can be considered as a result of the systemic influence of the tumor, and the obtained data can serve as the basis for a detailed immunophenotypic study of bone marrow in ovarian cancer.

Non-Hodgkin's lymphomas are extremely rare among all tumors of female reproductive system. Diagnostic mistakes and inadequate therapeu- tic tactics in these diseases are results of usual absence of alertness of gynecologists. The aims are to analyze reasons of diagnostic mistakes in patients with non-Hodgkin's lymphomas of female reproductive system and to discover definitive clinical and morphological characteristics of female reproductive system lymphoid tumors. During the period between 1989 and 2006, 305 cases of primary extranodal non-Hodgkin's lym- phomas were detected; female reproductive system was affected in 7% of patients (totally 40 patients), which were included in investigated group. In the whole analyzed group of women (n=40, median age 43 yrs, range 17-84 yrs), patients with primary lesion of female reproductive system had median age of 40 yrs and with secondary involvement - 46 yrs. Most of patients were fertile (60%, n=24). Such tumors was localized in breast in 40% of cases (n=16), in ovaries - 20% (n=8), in uterine corpus - 12,5% (n=5), in uterine cervix - 15% (n=6), and in vagina - remaining 12,5% (n=5). Average time from diagnosis to beginning of the treatment was 7,5 months. As a result, the onset of specific therapy was delayed in 65% cases (n=26) and 50% (n=20) underwent unneeded surgery. Diagnostic mistakes lead to inadequate treatment. Extranodal non-Hodgkin’s lymphomas of female reproductive system, both primary and secondary, are rare pathology. Primary lesion is more typical for older women, sec- ondary is mainly affecting younger women (in reproductive period). Chemotherapy response and prognosis are better in primary cases.

The purpose of the study was to define the factors influencing the development of a recurrence depending on the volume of surgical intervention and to investigate the possibility of performing organ-saving surgery (OSS) for centric breast cancer.The study used the clinical findings of 200 patients treated at the Department of Radiosurgery, N.N. Blokhin Russian Cancer Research Center in 1996 to 2006. According to the volume of surgical intervention, the patients were divided into 2 groups: 1) 106 patients who had undergone radical mastectomy; 2) 94 patients who had undergone radical resection. According to our data, the disease progressed in 32 (16%) cases. There were 12 local recurrences: in 8 (7.5%) and 4 (4.2%) cases after radical mastectomy and radical resection, respec- tively. The findings suggest that OSS may be performed after carefully patient selection, with all contraindications being kept in mind.

The BCIRG 001 study has shown that a combination of Taxotere, doxorubicin, and cyclophosphomide (TAC regimen) is more effec- tive than the standard FAC (5-fluorouracil, doxorubicin, cyclophosphomide) regimen in adjuvant chemotherapy of operable breast cancer (BC) with mestastases to regional lymph nodes. With higher efficacy, TAC regimen was more toxic: the incidence of febrile neu- tropenia was 24.7%. According to the current EORTC and ASCO guidelines, the use of granulocyte colony-stimulating factors (G-CSF) for primary prophylaxis is indicated when the risk of febrile neutropenia is ≥20%. This study was designed to evaluate the safety of TAC regimen with G-CSF primary prophylaxis in adjuvant chemotherapy (CT) of BC .Patients with operable BC (T1—3N1M0) and Karnofsky performance status 80% received adjuvant TAC regimen after radical surgery: Taxotere 75 mg/m2, doxorubicin 50 mg/m2, and cyclophosphomide 500 mg/m2. G-CSFs were administered in the standard doses for 5—7 days starting from cycle 1 of CT, for primary prophylaxis of febrile neutropenia.One hundred and one patients have been treated since 2006. Mean age was 47.5 years (range 25—67 years). Almost half (48.5%) of the patients had Stage IIIa disease, Stages IIa and IIb had 18.8 and 27.7% of patients, respectively.The tumor was estrogen receptor-positive in 57.4% of the patients and progesterone receptor-positive in 62.4%. Overexpression of Her- 2/neu receptor was documented in 49.5% of cases. The mean number of cycles per patient was 5.8. Ninety-one (90.1%) patients have received a complete course of 6 TAC cycles. The duration of prophylactic use of lenograstim or filgrastim during one CT cycle was 5.9 and 5.6 days, respectively.Episodes of febrile neutropenia were observed at 19 (3.2%) CT cycles in 9 (8.9%) patients. Neutropenic infections were recorded at 4 (0.78%) cycles in 3 (3%) patients.Thus, the use of GCSF substantially reduces the incidence of TAC-associated febrile neutropenia and infectious complications and ensures a safe and complete course of effective adjuvant CT for the vast majority (90.1%) of patients. The data presented suggest that there is a need for primary prophylaxis with G-CSF in all BC patients receiving adjuvant TAC.

The paper gives the results of studying the genes of epidermal growth factor receptor (EGFR) and topoisomerase IIα (TOP IIα) in patients with triple-negative breast cancer (BC). It is suggested that the lack of EGFR gene amplification might serve as a factor of good prognosis. TOP IIα gene amplification usually occurs in the tumors responsive to chemotherapy including anthracycline drugs. The altered status of the above genes should be interpreted in the context of aneusomy of chromosomes 7 and 17, on which they are located. No association was found between the pattern of EGFR and TOP IIα gene abnormalities and the basaloid phenotype of BC.

The huge global burden of oncological diseases is growing and measures to counter this complex challenge are high on national health agendas. The Russian National Long-Term Oncology Strategy 2030 defines priorities, goals and directions in the fight against cancer. Italso contains action plans for more effective prevention, earlier and more specific diagnosis and more effective treatment options. Against this backdrop, experts now suggest to complement standard oncology treatment strategies by adding Patient Blood Management (PBM). For many clinical disciplines where a low blood count and considerable blood loss are commonly encountered, this bundle of care is the new standard. Based on clinical and scientific evidence, it aims to optimise medical and surgical patient outcomes by clinically managing and preserving a patients blood. The principles of this comprehensive concept can and must be transferred to oncology, thus offering value in improving cancer care and the efficacy of medical institutions. Accumulating evidence demonstrates that anaemia and iron deficiency, but also thrombocytopenia, blood loss and coagulopathy are independent risk factors for adverse patient outcomes including morbidity, mortality, reduced quality of life and prolonged average length of hospital stay in both surgical and medical patients. For the timely and effective detection and correction of these risk factors, an international network of multi-disciplinary clinicians and researchers has developed PBM. The rapidly growing body of evidence for PBM not only shows improved patient outcomes, but also reduced resource utilisation including the use of allogeneic blood components. The reduction of allogeneic blood transfusion further improves patient safety and outcomes, since transfusion is another independent risk factor for adverse outcomes. Supported by WHO endorsements and following the recommendations of an increasing number of state or national health authorities, PBM is about to become a new standard of care. However, even though the aforementioned risk factors are highly prevalent in oncology settings due to chemo-/radiotherapy and the pathology of the disease, the integration of PBM in standard oncology treatment pathways is lagging behind. Thus, and in support of the Russian National Long-Term Oncology Strategy 2030 to improve quality of oncological care, with the support of the National Association of Specialists in PBM (NASPBM), the PBM Oncology Working Group of the Russian Federation was created, consisting of national and international experts in oncology and PBM. On July 9, 2020, the Working Group met to discuss the rationale for PBM in oncology and to assess the need to implement PBM in Russian oncology care. As a result, the Group recommended to include PBM as an integral part of standard oncology treatment pathways, delineated the action required from facilitating stakeholders in the Russian Federation, determined a roadmap for implementation and developed a national resolution as a call to action on the matter. Presented herein, this resolution acknowledges the global and local impetus to reduce cancer mortality, and the rationale for PBM interventions to improve patient outcomes and alleviate the social and economic burden of cancer on the healthcare system.

The analysis of the current strategy for the treatment of advanced HR+/HER2-negative metastatic breast cancer (mBC) was carried out, the criteria for hormone sensitivity and hormone resistance were given, and the changes in the classification of tumors were reflected taking into account the level of expression of estrogen receptors. A detailed characterization of a new potential marker of acquired hormone resistance - activating somatic mutation of the estrogen receptor gene ESR1, leading to constitutive ligand-independent activity of the estrogen receptor is given; describes the predictive and prognostic role of ESR1 mutation, its association with the clinical course of the disease and response to endocrine therapy. The paper presents studies to find the optimal treatment regimen after progression to CDK4/6 inhibitors, including the emergence of ESR1 mutations. The characteristics and key advantages of eribulin chemotherapy in patients with hormone-resistant mBC are presented, and preliminary results of the EMPOWER study on the potential for eribulin use after progression to CDK4/6 inhibitors are presented. This review will help form the concept of a personalized approach to the choice of a treatment strategy for hormone-resistant mBC.

Monoclonal gammopathy of renal significance (MGRS) is a new nosology in modern nephrology and oncohematology. MGRS is defined as kidney injury due to nephrotoxic monoclonal immunoglobulin produced by the B-cell line clone which does not reach the hematological criteria for specific treatment initiation. Monoclonal proteins pathological effects on kidney parenchyma result in irreversible decline of kidney function till the end stage renal disease that in line with the position of International Consensus of hematologists and nephrologists determinates critical necessity for clone specific treatment in patients with MGRS despite the absence of hematological indications for treatment initiation. Main challenge of MGRS in Russian Federation is an inaccessibility of an in-time diagnostic and appropriate treatment for the great majority of patients due to the following reasons: 1) limited knowledge about the MGRS among hematologists and nephrologists; 2) lack of necessary diagnostic resources in most health-care facilities; 3) lack of approved clinical recommendations and medical economic standards for treatment of this pathological entity. Consensus document comprises the opinion of experts leading nephrologists and hematologists of Russian Federation on the problem of MGRS including the incoherence in nosology classification, diagnostics approach and rationale for clone specific treatment. Consensus document is based on conclusions and agreements reached during the conference of leading nephrologists and hematologists of Russia which was held in the framework of symposia Plasma cell dyscrasias and lymphoproliferative diseases: modern approaches to therapy, 1516 of March 2019, Pavlov First Saint Petersburg State Medical University. The present Consensus is intended to define the principal practical steps to resolve the problem of MGRS in Russian Federation that are summarized as final clauses.Моноклональная гаммапатия ренального значения (МГРЗ) представляет собой новую нозологическую группу в современной нефрологии и онкогематологии. Под МГРЗ понимают поражение почек, обусловленное действием нефротоксичного моноклонального иммуноглобулина, продуцируемого клоном В-клеточной линии, который не достигает критериев, необходимых для начала противоопухолевой терапии по онкогематологическим показаниям. Результатом воздействия моноклонального белка на почечную паренхиму является неуклонное прогрессирование дисфункции почек вплоть до утраты функции органа, что в соответствии с единой позицией международного консенсуса гематологов и нефрологов определенно указывает на необходимость клон-ориентированного лечения МГРЗ, несмотря на отсутствие критериальных онкогематологических показаний. Основной проблемой МГРЗ в Российской Федерации является недоступность для большинства пациентов своевременной диагностики и лечения данной патологии, что обусловлено, во-первых, недостаточной осведомленностью гематологов и нефрологов страны в отношении МГРЗ, во-вторых, отсутствием в большинстве медицинских учреждений необходимых диагностических ресурсов, в-третьих, отсутствием утвержденных рекомендаций и медико-экономических стандартов лечения этой болезни. Текст настоящего консенсуса заключает в себе мнение специалистов РФ в отношении нозологической классификации, диагностики и подходов к терапии МГРЗ и основан на итогах проведенного совместного совещания ведущих гематологов и нефрологов страны. Совещание состоялось 1516 марта 2019 г. в рамках симпозиума Плазмоклеточные дискразии и лимфопролиферативные заболевания: новые подходы к терапии, проведенного в ФГБОУ ВО Первый СПбГМУ им. акад. И.П. Павлова. Настоящий консенсус гематологов и нефрологов призван наметить основные практические пути решения проблемы МГРЗ в РФ, которые кратко сформулированы в виде заключительных положений.

- Abstract
The article presents the results of determining the quality indicators of water from several ponds No. 3 (drain), No. 4 (non-drain), No. 8 (drain) Privolzhsky branch of the Federal State Budgetary Institution “Management “SARATOVMELIOVODKHOZ” of the Marksovsky district of the Saratov region. In the course of the studies carried out, it was revealed that during the growing season, under the influence of fish-breeding processes and the ability of reservoirs to self-purification, as a result of the vital processes of various hydrobionts, the chemical and microbiological characteristics of water changed for the better. Introduction. Our country is characterized by a wide variety of different conditions, including hydrological and climatic, which entails different types of environmental management, as well as differences in the intensity of development. Currently, there is a progressive deterioration in the quality of the aquatic environment, which is a threat to Russia’s vital national interests in the areas of environmental, food and national security. Environmental protection has recently become of world importance. Pollution of water resources, atmospheric air, soil and vegetation occurs due to urbanization and intensification of industrial and agricultural production. More than 1900 rivers flow through the territory of the Saratov region, there are 3800 reservoirs, 32 underground water deposits and about 700 lakes. Their distinctive features include a small area, often-changing outlines and volumes. The sustainability of food production is increasingly ensured by the rational and efficient use of water resources and methods of their conservation, consisting mainly in the development and organization of irrigation, including the rational development of water resources for dry farming, water supply for livestock, inland fisheries and agroforestry. Achieving food security is one of the top priorities for many states, and agriculture should not only provide food for the growing population, but also contribute to resource conservation and efficient environmental management in various areas.
