Timely diagnosis and the introduction of new effective treatments, including intensive radiation and chemotherapy regimens, have significantly improved survival forecasts in recent years. At the same time, the use of these types of treatment increases the risk of complications, one of which includes chemotoxic cardiopathies. In this regard, timely detection and treatment of complications from the cardiovascular system in patients receiving chemotherapy courses in combination with surgical methods of treatment is important. This paper presents an assessment of the significance of the use of cardiomarkers in the early diagnosis of acute myocardial infarction that developed during chemotherapy in a patient with tongue cancer with a complicated cardiac history. Patient M., 45 years old, was admitted for surgical treatment for cancer of the tongue St. IVA, T4aN1M0, cl. gr. 2. Planned laboratory and instrumental studies were performed. Contraindications for surgical treatment were not identified. A preoperative course of chemotherapy was performed, against the background of which the patient's condition worsened with symptoms of acute cardiopathy. A second ECG was urgently performed, as a result of which an increase in the ST segment in III, aVF was established, as well as a study of the concentration of cardiomarkers: highly sensitive troponin I, N-terminal propeptide of natriuretic hormone, creatine phosphokinase MB, myoglobin, the dynamics of changes in the level of which indicated the development of acute coronary syndrome. The complex application of diagnostic procedures, including the determination of the level of cardiomarkers, made it possible to timely diagnose the development of acute type 1 myocardial infarction in a patient with tongue cancer on the background of chemotherapy. When analyzing the entire array of clinical and laboratory data, the leading initiating factor that played a decisive role in the development of myocardial infarction in this case was, in our opinion, a preoperative course of polychemotherapy with paclitaxel and carboplatin, which have cardiotoxicity. Thus, the category of patients with an initial unfavorable background, due to a common malignant process and the presence of a history of cardiodisfunction, requires more careful preparation for preoperative courses of polychemotherapy, including cardiotropic therapy with mandatory monitoring of the level of the main cardiomarkers. The most significant changes were in the levels of creatine phosphokinase MB, troponin I, and myoglobin, which were recorded in the first hours of myocardial infarction. An association was found between an increase in troponin I concentration and an increase in the ST segment of the electrocardiogram.","PeriodicalId":22147,"journal":{"name":"South Russian Journal of Cancer","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83081901","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}

This is due to the topographical and anatomical features that limit the operating field and the proximity of the internal carotid artery, which penetrates into the skull without branches. Her injury and bandaging are fraught with lethality. In the postoperative period, due to a violation of the function of swallowing, there is a stagnation of oral fluid in the oral cavity, which pro[1]motes healing by secondary tension. The functions of the oropharynx are impaired: swallowing, chewing, breathing and speech.Purpose of the study. To develop an operation in patients with advanced cancer of the oral cavity and oropharynx, allowing to visualize the area of the tumor with it’s radical removal and postoperative healing without suppuration.Patients and methods. We’ve operated a patient with advanced cancer of the oral cavity and oropharynx with me[1]tastases to the cervical lymph nodes (T4 N1 M0 – IV st.). Cervical lymphodessection and removal of the tumor from the oral cavity and oropharynx was performed according to the method developed at the National Medical Research Centre for Oncology of the Ministry of Health of Russia: the tumor was removed after a preliminary modified mandib-ulotomy. Good visualization allowed for a radical operation, after which a urostoma was formed, which promotes the free flow of oral fluid from the oral cavity, without its stagnation and without suppuration of the tissues. The jaw was restored with two titanium mini-plates.Results. The healing was carried out by primary tension. On the 7th day after the operation, breathing was restored[1]decanulated. On day 20, epithelialization of the wound surface of the oral cavity and oropharynx occurred. The nasoesophageal probe was removed. Plastic orostoma was produced.

To assess the state of renal function in the application of therapeutic plasmapheresis in order to correct the disorders accompanying the development of preclinical stage of AKI in patients after partial nephrectomy under conditions of warm ischemia.Patients and methods. We examined 119 patients (average aged 57.6±7.8 years) from 2018 to 2019, who underwent open or laparoscopic kidney resection for cancer according to elective indications and with the usage of standard WIT technique within 15-21 minutes. Patients with a high risk of developing a clinical stage of AKI (n=21) were divided into 2 groups: in group I (n=10), patients continued to receive standard nephroprotective therapy, in group II (n=11), 24 hours after surgery, therapeutic plasmapheresis was performed according to the TPE (Therapeutic plasma exchange) protocol. During 7 days after the surgery patients in both groups were monitored daily for the rate of hourly diuresis, serum creatinine, and creatinine GFR. The presence of significant differences in the groups was evaluated using the STATISTICA 12.6 software package and the differences between the samples were considered significant at p<0.05.Results. The development of the clinical stage of AKI in group I was detected in 80.0 % of cases, in group II in 9.0 % of patients (p=0.0019). The rate of diuresis in group II was significantly higher: by more than 2 times by day 3, by 90.0 % on day 4, by 81.4 % on day 5, by 36.8 % on day 6, and by 25.4 % on day 7 (p<0.05). The average increase in creatinine in group I was significantly higher: more than 5 times on day 5 and more than 4 times on day 6 and 7 of the study (p<0.05). GFR in group II was significantly higher on day 3 (65.3 %), day 5 (54 %), day 6 (39.2 %) and day 7 (50 %) (p<0.05).Conclusion. Therapeutic plasmapheresis is highly effective in the correction of renal function disorders after kidney resection under WIT conditions and demonstrates an advantage in reducing the risk of developing a clinical stage of AKI in comparison with preventive measures that include standard nephroprotective infusion therapy.","PeriodicalId":22147,"journal":{"name":"South Russian Journal of Cancer","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83467627","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}

Staged orthopedic treatment was used to improve the quality of life of patients who underwent radical maxillofacial surgeries for cancer.Patients and methods. 197 patients receiving treatment for maxillofacial cancer were observed at the Department of head and neck tumors, National Medical Research Centre for Oncology of the Ministry of Health of Russia, in 1998- 2018. All patients underwent radical surgical treatment resulting in postoperative defects of the upper jaw, soft tissues of the zygomatic- buccal-orbital region, nose, or auricle.Results. Removable obturator prostheses with various supporting and retaining elements were made for 159 (80.7 %) patients. Individual facial prostheses were made for 38 (19.3 %) patients: 17 (44.7 %) – external orbital prostheses, 14 (36.8 %) – external nasal prostheses, 6 (15.8 %) – external zygomatic- buccal-orbital prostheses, 1 (2.7 %) – external auricle prosthesis. Combined prostheses were made for 4 patients– removable upper jaw obturator and nose prosthe[1]sis; removable upper jaw obturator and eye prosthesis. Combined prostheses were fixed to each other using magnets. The results of maxillofacial prosthetics were evaluated according to the aesthetic requirements of the patients and their quality of life. Maxillofacial prostheses allowed a complete restoration of chewing, swallowing, and speaking, restored facial deformation, and improved the appearance of patients.Conclusions. Timely and comprehensive orthopedic treatment of patients with postoperative maxillofacial defects after radical surgeries for malignant tumors takes the main place in the complex of rehabilitation measures. Early elimination of extensive defects is aimed at maximum restoration of oral dysfunctions and appearance preservation. The apparent advantages of maxillofacial prostheses involve improvement of social adaptation and the quality of life of patients, which promotes complete rehabilitation and a return to socially useful activities.","PeriodicalId":22147,"journal":{"name":"South Russian Journal of Cancer","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84780938","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}

We retrospectively analyzed the digital archive of 368,157 pathology reports of the National Medical Research Centre for Oncology of the Ministry of Health of Russia from 2000 to 2019. For the study, 4,857 pathology reports of patients operated for gastric malignancies (ICD-X codes: C16.0 – C16.9) were selected for the period from 2000 to 2019.Results. The analysis of 368,157 protocols of the digital archive of PD revealed 4,614 malignant epithelial tumors of the stomach: tubular adenocarcinoma – 2,958, signet ring cell carcinoma – 791, undifferentiated cancer – 565, mucinous adenocarcinoma – 210, neuroendocrine neoplasia – 90. A significant increase in the ICD-O codes for \"adenocarcinoma NOS\" was found in 2018 and 2019. The pathology reports for these 2 years were reviewed by an independent pathologist and changes were made to the ICD-O codes according to the WHO classification digestive system tumors 2019. The adenocarcinoma NOS (8140/3) was replaced by the codes: tubular adenocarcinoma (ICD-O: 8211/3) – 41%, papillary adenocarcinoma (8260/3) – 9% and adenocarcinoma with mixed subtypes (8255/3) – 29%.Conclusion. The study, based on analysis of coding ICD-O stomach MN demonstrated the importance of digital archive at the PD, as a tool for rapid static analysis pathology reports and quality control of coding.

Technical advances in modern oncology resulted in developing a method for transanal tumor removal with a number of advantages: radical surgery, adequacy, and functionality. This technique can be used in benign and malignant rectal tumors. One of its main advantages involves a small number of postoperative complications, while intra- operative complications such as penetration into the free abdominal cavity during transanal endoscopic resection of the rectum are quite rare.
