Cutaneous leiomyosarcomas could have superficial and deep forms, while subcutaneous leiomyosarcomas are usually nodular. The tumor can spread to the underlying muscle fascia. The immunophenotype of leiomyosarcoma is determined by the following antibodies: ASMA, desmin, and N-caldeston; expression of PanCK is also possible. Researchers do not have any common opinion on the clinical course and biological behavior of cutaneous leiomyosarcomas. This is probably due to the tumor heterogeneity and the carcinogenesis specificity associated with molecular genetic changes. We detected these tumors at the histological examination which resulted in an analysis of the literature and our own material. We analyzed cutaneous tumors diagnosed in 2522 patients during 5 years (2016–2020). Squamous cell and basal cell histotypes were the most common ones. We did not diagnosed cutaneous leiomyosarcoma in our material during this period. This article presents two cases of cutaneous leiomyosarcoma localized in the scalp and calf skin. Morphological and immunohistochemical profiles of the tumors are described. The immunohistochemical analysis confirmed the morphological diagnosis and established the tumor immunophenotypes. The morphological diagnosis in one case was complicated due to the rarity of this pathology and the ambiguity of the interpretation of histological changes. Analysis of histological preparations and immunohistochemical study allowed verification of the tumor as leiomyosarcoma with its characteristic immunophenotype. All of the above demonstrate the need to perform morphological and immunohistochemical tests in specialized research cancer centers.","PeriodicalId":22147,"journal":{"name":"South Russian Journal of Cancer","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79694865","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}

An analysis of sonography potential in the primary diagnosis and clinical staging of tongue cancer.Patients and methods. The study included 18 patients aged 40–70 years with tongue tumors. The majority accounted males – 14 (77.7 %). Women were represented by 4 (22.2 %) examinees. Ultrasound examinations were performed using expert-class ultrasound systems with broadband linear multifrequency transducers. Transoral examination with linear transducers required tumor location in the anterior and lateral parts of the oral tongue. During ultrasound examinations we evaluated: tumor shape, tumor invasion depth; tumor sizes – width and thickness; tumor echogenicity and structure; tumor vascularization in Doppler modes. The results were compared with the data of histological examination.Results. Transoral ultrasound examination of patients with tongue cancer allows clear visualization of the tumor and assessment of it’s spread. The study showed that the round shape of tongue tumors prevailed in 13 (72.2 %) patients, the tumor echo structure in 10 (55.5 %) was heterogeneous, the contours were even and clear in the majority of patients – 13 (72.2 %), all tumors showed a reduced acoustic density, the depth of invasion ranged from 2 to 6 mm in 8 (44.4 %) patients and exceeded 6 mm in 6 (33.3 %) patients, which corresponded to stages III and IV of the diseas. Doppler ultrasonography recorded intense intratumoral blood flow in 100 % of cases. In 8 (44.4 %) cases, metastatic lesions of the cervical lymph nodes were observed.Conclusion. Transoral ultrasound diagnosis of tongue cancer is a highly informative, safe and modern method providing surgeons with information that helps in choosing the scope of surgical treatment and in determining the disease prognosis at the preoperative stage.

Determine the content of cancer stem cells (CSCs) in the tumor tissue (TT) and perifocal tissues (PT) in muscle-non-invasive bladder cancer.Materials and methods. We’ve examined fragments of TT and PT of 7 muscle-non-invasive bladder cancer (NMIBC) after surgical intervention – transurethral resection of the urinary bladder (TUR). In tissue samples that were used to obtain cell suspension of TT and PT using the BD Medimachine apparatus (BD, USA) was treated with monoclonal antibodies CD45-APCCy7, CD44-FITC, CD133-РЕ, CD24-PE (BD, USA) and were assessed on flow cytometer FacsCantoII (BD, USA). The percentage of cells with CSC phenotypic markers was determined in the analysis sample: CD45-CD44+CD24+, CD45-CD44+, CD45-CD24+, CD45-CD133+, CD45-CD44+CD133+. The presence of significant differences in the groups was evaluated using the STATISTICA 13 software package and the differences between the samples were considered significant at p < 0.05. The percentage of cells of the corresponding phenotype was calculated relative to the total number of cells. The percentage of cells with the corresponding phenotype was calculated relative to the total number of cells.Results. The relative numbers of cells with CSC phenotypic markers, such as CD24, CD44, were 77 % and 58 % higher in TT than in PT: 18.3 ± 3.5 vs. 4.3 ± 2.1, p ≤ 0.044 and 15.5 ± 5.3 vs. 6.5 ± 0.8, p ≤ 0.043, respectively.

For the experiment, we used female C57Bl/6j mice, which were inoculated subcutaneously with syngeneic tumors: Lewis lung carcinoma (LLC) and B16-F10 melanoma. RU‑185 was administered intragastrically to animals in a volume of 0.3 ml for 10 days, 1 time per day. For both tumors, depending on single doses of the substance for administration, groups were divided: 1st and 4th – 50 mg/kg, 2nd and 5th – 220 and 3rd and 6th – 500 mg/kg. The control groups were injected intragastrically with physiological saline in the same volumes and according to the same scheme. The following parameters were assessed: tumor volume, increase in life expectancy (T/S, %) and tumor growth inhibition index (TGI, %).Results. For animals with LLC in the 2nd group there is an increase in the indicator of life expectancy (T/S 162.3 %), and in the 3rd group there is a tendency to an increase in the T/S indicator. On the 1st day after the end of treatment in the 2nd and 3rd groups TGI was 73.0 % and 30.1 %, respectively (р < 0.05).

A retrospective analysis of the immediate results of performing anterior rectal resections in cancer. Materials and methods. In the Department of Abdominal Oncology No. 1 with a group of X-ray vascular methods of diagnosis and treatment of the clinic of the National Medical Research Centre for Oncology of the Ministry of Health of Russia treatment for rectal cancer operations of anterior rectal resection were performed in 334 patients, while in 143 (42.8 %) cases they were low. As a standard, total mesenteric excision and lymphoid dissection in volume D2 were performed. Combined surgical interventions were performed in 68 (20.4 %) patients for locally spread tumors. As a rule, they were resection in nature and were performed with tumor infiltration of adjacent organs (bladder with ureters, ovaries, uterus, vagina, small intestine, abdominal wall). Colorectal anastomosis using crosslinking devices was formed in all cases, in 316 (94.6 %) cases it was a \"side – to-end\" junction, in 18 patients – \"end-to-end\". A preventive proximal intestinal stoma was formed in 73 (21.9 %) cases, where 67 cases it was an ileostomy, and 6 – a transversostomy. The preventive proximal intestinal stoma was not formed among 261 patients. Results. After performing anterior resections for rectal cancer operations, the complications developed in 75 (22.5 %) patients. The most threatening and dangerous complication was the failure of the colorectal anastomosis, which was noted in 12 (3.5 %) cases.This complication occurred in 8.2 % (6 patients out of 73) of preventatively stoma-treated patients, in 2.3 % of patients without a stoma (6 patients out of 261).Conclusion. The use of a preventive proximal intestinal stoma allows you to form a colorectal anastomosis even in the presence of complicated forms of rectal cancer. The number of complications directly referred to the formation of a preventive proximal intestinal stoma is relatively small, but when planning surgery for uncomplicated rectal cancer, the probability of their possible occurrence should be taken into account.","PeriodicalId":22147,"journal":{"name":"South Russian Journal of Cancer","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81792505","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 most common complication after elective lung resections is an alveolar-pleural fistula or prolonged air leakage. This clinical phenomenon occurs as a result of communication between the alveoli of the lung parenchyma distal to the segmental bronchus and the pleural cavity. In most cases, air leakage through the drains is eliminated spontaneously, but the frequency of prolonged pneumostasis absence in the postoperative period can reach 25 %, which has a negative effect on the outcomes of surgical interventions due to the development of pneumonia and empyema. Long-term drainage of the pleural cavity does not always end with aerostasis and requires repeated invasive interventions. One of the ways to achieve the tightness of the lung tissue involves various methods of chemical pleurodesis, which is a surgical manipulation – the introduction of a sclerosing chemical substance into the pleural cavity by spraying medical talc through a trocar or a injecting tetracycline solution into the pleural drains. The chemical causes aseptic inflammation and adhesions between the visceral and parietal pleura, followed by obliteration of the pleural cavity. The sclerosant introduction is accompanied by severe pain that can provoke respiratory and/or hemodynamic deficits, up to apnea and life-threatening heart rhythm disturbances. Pain relief during chemical pleurodesis is obviously an important factor in the prevention of a number of complications in patients undergoing surgery for lung cancer. Bolus intravenous injections of narcotic analgesics lead to an analgesic effect, but a short-term one due to the absence of a depot in the body and a sharp drop in the drug concentration in the blood serum. Unfortunately, this method of introducing narcotic drugs can cause various complications in weakened and elderly cancer patients, such as respiratory depression and cardiac arrest. The TTS action is characterized with continuous dosing and the creation of a constant concentration of the narcotic drug over a certain period of time. This method provides a multilevel and systematic approach to pain relief, reduces toxicity and minimizes the inhibition of the central mechanisms of external respiration regulation without causing respiratory and cardiac disorders in patients who underwent lung resection.","PeriodicalId":22147,"journal":{"name":"South Russian Journal of Cancer","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73732880","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}
