Compared with other histological types of salivary gland cancer, it usually has a more latent clinical course with a low incidence of spread to regional lymph nodes. However, after removal of the primary tumor, local and distant relapses are quite common. In addition, the presence of prognostic factors such as metastases in the lymph nodes of the neck, low degree of tumor differentiation, perineural and lymphovascular invasion contributes to an increase in the frequency of distant metastasis with a poor prognosis. Cases of atypical arrangement of salivary gland tissues with extranodal heterotopia are rare. In the head and neck region, different localizations of heterotopia of salivary gland tissues have been described, but the pterygopalatine fossa was not mentioned in the available sources. The difficulty of histological diagnosis when verifying heterotopia of the salivary glands may be due to the phenomena of chronic inflammation, lymphoid infiltration, tissue fibromatosis and the development of metaplasia. The rare occurrence of heterotopia of the salivary glands, the difficulties of its diagnosis and the lack of a unified approach to surgical treatment require consideration of each individually identified case. The law of paired cases is implemented in the interpretation of the presented clinical cases, when the identification of individual extraorgan foci of adenoid cystic cancer of the pterygopalatine space may be associated with a rare extranodal heterotopia of salivary gland tissue. The primary multiplicity of malignant lesions of the major salivary glands and heterotopia of salivary gland tissue can be both synchronous and metachronous. Adenoid cystic cancer of the pterygomaxillary fossa, as a component of multicentric growth of various localizations, clinically confirmed the recurrent nature of the course, the tendency to distant metastasis and generalization of the malignant process.","PeriodicalId":509207,"journal":{"name":"Russian Journal of Oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139147982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The methodology was developed using the data from the population-based Cancer Registry of the Altai Territory, created at the Altai Regional Oncology Center in Barnaul, Russia. At the moment the Cancer Registry included information on 308,550 patients with malignant neoplasms, including 31,783 women with breast cancer. On the basis of the method of breast cancer risk assessment proposed by Lazarev A.F. (patent number: RU 2651131 C1) an automated program for early diagnosis of breast cancer has been developed (state registration certificate for computer program No. 2019661203). The program significantly reduces the time for risk assessment and allows to form groups of high breast cancer risk, increases the efficiency of breast cancer diagnostics, and serves as a basis for development of set of targeted preventive measures specific for each patient. Testing of this technique included assessment of 512 patients, which resulted in forming of a high-risk precancer group of patients having individual risk of developing breast cancer either increased or high or absolute. 92 patients were determined to belong to the high risk pre-cancer group. The patients had a complex of in-depth examinations (including ultrasound, mammography, MRI with dynamic contrast and breast biopsy if indicated). 7 of 92 patients (7.6%) were diagnosed with breast cancer, all at early stages (I or II). It allows to suggest implementation of the method with the aim to assign in-depth examination in more targeted manner to patients at high risk of breast cancer and to contribute to detection the cancer in the early stages.","PeriodicalId":509207,"journal":{"name":"Russian Journal of Oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139142751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Particular attention is drawn to the combination of interferon- and recombinant tumor necrosis factor-thymosin--1, which can activate an antitumor immune response, stimulate apoptosis of tumor cells, have a direct antiproliferative effect, cause destruction of neoplasm vessels, and stimulate tumor tissue necrosis.Methods: This paper presents the results of a follow-up of 24 patients with histologically confirmed pancreatic carcinoma. Some patients received combined immunotherapy as the only method of treatment, when the possibilities of standard therapy were exhausted, there were serious complications of anticancer treatment, severe concomitant pathology that did not allow the planned treatment to be carried out in full, or when the patient refused to use cytostatics. In other cases, the introduction of immunotherapeutic drugs was carried out against the background of other antitumor treatment of the 1st or 2nd line, prescribed in connection with the progression of the disease.Results: As a result of the use of a combination of interferon- and recombinant tumor necrosis factor-thymosin--1, patients noted an improvement in the tolerability of the main antitumor treatment, additional manifestations of toxicity from the use of immunodrugs were not observed. The existence of an average positive correlation (r=0.57, p=0.0004) between the level of TNF and the value of the Karnofsky index was revealed, indicating that an increase in the content of TNF is accompanied by an increase in the functional activity of patients. According to computed tomography data, in accordance with the RECIST 1.1 criteria, one patient had a partial response of the tumor to the treatment, in 9 - stabilization of the tumor process, in other cases, observation continues.Conclusions: The data presented are of a pilot nature.

The main purpose of this article is to research nosological characteristics of lung cancer in the context of HIV infection, HIV-associated risk factors during ART and compare with global trends of this problem. Retrospectively were analyzed the medical documentation of 98 patients with lung cancer and HIV-infection, who were in database and received specialized treatment in St. Petersburg from 2008 to 2018 years. There are several important questions regarding to lung cancer with HIV-infection. HIV-infected lung cancer patients are younger than HIV-negative, have a more advanced disease and that is more difficult to treat. The increased risk of lung cancer in HIV-positive population is multifactorial. The population was dominated by patients of young (18-44 years old) and middle (45-59 years old) ages, 45.9% and 42.9%, respectively, and 11.2% of elderly patients (60-74 years old), p0.001, which satisfies the global data of earlier incidence of lung cancer in people living with HIV. Adenocarcinomas were more common histological subtype of lung cancer as in the general population (p0.001). There was no static significance between high viral load and lung cancer, which can indicate the absence of a direct mechanism of HIV-carcinogenesis (90.8% of patients with low and medium viral load, p0.001).Nevertheless, the prevalence of 4-stage of HIV infection among lung cancer patients (p0.001) indicates a history of inflammatory diseases, including pulmonary diseases, as a result of induced immunosuppression due to CD8+T-lymphocyte dysfunction and the formation of a micro-tumor environment, which can be a prognostic unfavorable factor in the occurrence of lung cancer in this group of patients , as well as indirect mechanism of viral carcinogenesis. The presence of elderly patients (11.2%, MAX -71 years) indirectly indicates an increasing of period of life expectancy among this category of patients in Russia, making this area of research more actual.","PeriodicalId":509207,"journal":{"name":"Russian Journal of Oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-12-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139158354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental part of the work on laboratory animals has its own peculiarities in the field of preclinical research: a large number of animals and analog compounds in the series, two- and three-phase staging, and, consequently, high cost and labor-intensive execution. AIMS: Optimization of algorithms for screening preclinical in vivo studies of compounds with a suspected antitumor effect. MATERIALS AND METHODS: To form the algorithm in the preclinical study, primary data obtained using standard pharmacological (determination of the toxicity class index with a single intragastric injection, on tumor models - determination of antitumor and antimetastatic activity by the index of inhibition of metastasis, inhibition of tumor growth by weight, average life expectancy of animals) and morphological methods (autopsy, preparation of micropreparations with hematoxylin and eosin staining, as well as immunohistochemical study using monoclonal antibodies) with the selection of leading compounds for indepth study with a description of the mechanism of pharmacological activity. RESULTS: Based on a series of comparative experimental series, the following algorithm of preclinical in vivo study for newly synthesized compounds with an alleged antitumor effect has been tested. Stage 1. Determination of the toxicity class with a single intragastric administration to Wistar rats according to the OECD 420 protocol and selection of candidates for antitumor drugs according to the principle of the greatest safety of use. Stage 2. Determination of the presence/absence of pharmacological activity of the tested compounds.
