RECIST 1.1, mRECIST 1.1: RADIOLOGICAL ASSESSMENT OF TUMOR RESPONSE TO CHEMOTHERAPY (literature review)

Определение изменений опухолевого роста является важной характеристикой клинической оценки терапии рака - как уменьшение размеров опухоли (объективный ответ), так и прогрессирование заболевания являются полезными конечными точками клинических исследований. Критерии RECIST были впервые опубликованы в 2000 г. и с тех пор начали применяться в мировой онкологической практике для оценки эффективности лечения. В 2009 году критерии RECIST 1.0 были пересмотрены и дополнены новыми данными RECIST 1.1 (2009 г.). Учитывая применение химиотаргетной терапии и особенности ответа на нее опухоли, предложены SACT критерии, модифицированные критерии RECIST (mRECIST) как способ адаптации критериев RECIST. Современные знания критериев оценки лечения солидных опухолей поможет лучевым диагностам правильно интерпретировать результаты исследований. В работе представлен обзор научных исследований по критериям оценки опухолевого ответа на лечение по данным радиологических исследований. Determining of tumor changes is an important characteristic of the clinical evaluation of cancer therapy - both tumor shrinkage (objective response) and disease progression are useful endpoints of clinical trials. The RECIST criteria were first published in 2000 and since then have been used in the global oncological practice to assess the effectiveness of treatment. In 2009, the RECIST 1.0 criteria were revised and supplemented with new data from RECIST 1.1 (2009). Taking into account the use of target chemotherapy and the peculiarities of the tumor response to it, the SACT criteria and modified RECIST criteria (mRECIST) are proposed as a way to adapt the RECIST criteria. Modern knowledge of the criteria for ASSESSMENT OF TUMOR RESPONSE will help radiologyst to correctly interpret the research results. The paper provides an overview of scientific studies on the criteria for evaluating tumor response to treatment based on radiological studies.

Immunocorrective treatment use in the prevention of hematological and infectious complications of chemotherapy in cancer patients

The article analyzes the use of immunocorrection of hematological toxicity that occurs during chemotherapy in cancer patients. Hematological toxicity, along with cardiotoxicity and hepatotoxicity often prevents the implementation of the entire planned volume of chemotherapy.Standard therapy (colony stimulating factor use) may not be always available and there is a need to develop new and more effective strategies for supportive care. Among the various methods and approaches, the most promising may be the use of systemic immunecorrecting therapy, the possibilities of which are far from being realized in oncological practice.The analysis of the studies summarized in this review demonstrates the effectiveness of the immunomodulator/immu‑ noadjuvant – azoximer bromide in hematological toxicity prevention in patients with various types of cancer.

The importance of precancerous diseases in oncological practice

The term precancer, although not entirely accurate, is ingrained and widespread. Clinicians understand by it such local changes in tissues and organs that predispose to the development of cancer and prepare the ground for its occurrence. Everyday clinical observations and numerous experiments confirm such a generally accepted view, which does not exclude, however, the possibility of tumor development even without precancerous changes. The latter is difficult to prove, but it must be admitted in the absence of any indications in the anamnesis in adults, and especially in young people.

Asco annual meeting 2021 Some news to use in our oncological practice

Every year, ASCO Annual Meeting provides new options for the treatment of our patients What are the news this year about breast cancer? I would initially highlight the presentation made in the plenary, results that modify our decisions in daily practice.

Simulation Training for the Installation of Spinal (Epidural) Port Systems

Currently, the procedure for installing spinal and epidural port systems in oncological practice for the treatment of pain is very relevant.

Radiotherapy of Malignant Tumors: Photons or Protons? Part 1. Bragg Peak and the Brief Characteristics of a Proton Beam

The first paper of a series of three publications briefly presents the characteristics a proton beam, as well as the information of companies producing noncommercial techniques for photon and proton therapies. The following second and third parts will briefly consider the clinical and economic efficiency of proton versus photon radiotherapy in the treatment of cancer patients and prospects for its development in oncological practice.
