Introduction. primary mucinous carcinoma of the eyelid skin is a rare adenocarcinoma of skin glands. This tumor rarely metastasizes but frequently recurs.The study objective is to describe a rare clinical case of primary mucinous carcinoma of the eyelid skin, present macroscopic, histological and immunohistological descriptions of this pathology.Clinical case. male, 66 years old, sought medical care due to a neoplasm of the lower eyelid. macroscopically a subcutaneous node 1.2 × 1.0 cm was observed, of yellow-brown color, gelatinous in section. microscopic examination showed that the tumor consists of islands of epithelial cells surrounded by mucinous “lakes”. Immunohistochemical examination showed Ck7, estrogen, p53 expression in the tumor cells, as well as absence of Ck20 expression. Based on the data of macro-, microscopic and immunohistochemical examinations, primary mucinous carcinoma of the eyelid skin was diagnosed. Observed morphological signs of this tumor allow to differentiate it from cancer metastasis.Conclusion. primary mucinous carcinoma of the skin should be differentiated from metastasis of mucinous carcinoma of the breast, lung, colon, et al. macro- and microscopic signs of this tumor are subjective. Immunohistochemical examination is a more reliable diagnostic tool.

Introduction. Treatment with the initial stage of the disease causes a high need for the use of organ-preserving treatment methods, which are actively developing and improving. One of the modern and promising methods is endolaryngeal resection of the larynx.Aim. To evaluate oncological effectiveness and functional results of endolaryngeal laser resections in cancers of the voice box.Materials and methods. The study included 139 patients with squamous-cell carcinoma of the voice box between the ages of 26 and 81 years who received treatment at the Department of Head and Neck Oncology of the federal medicalBiological Agency of the Russian federation between 2015 and 2020. All patients underwent standard examination to diagnose oncological diseases and were diagnosed in accordance with the Tumor, Node and metastasis (TNm) international system. In 90 (64.7 %) of 139 patients, squamous-cell laryngeal cancer T1N0m0 was diagnosed, in 49 (35.3 %) patients – T2N0m0. All patients underwent surgical treatment in the form of endolaryngeal laser resection according to the plan developed during an oncological council.Results. After endolaryngeal laser resections, 3-year recurrence-free survival for cancer of the voice box, stages т1 and т2, was 92 and 84.2 % respectively. Temporary disruption of separating function of the larynx in patients with stage T2N0m0 was observed in 6.1 % cases, decreased vocal function in 100 % of cases, granuloma formation in the postoperative period in 19.4 % of cases, formation of a scar narrowing the laryngeal lumen in 4.3 % of cases.Conclusion. High 3-year recurrence-free survival as well as small percentage of postoperative complications and severe functional abnormalities show high effectiveness of endolaryngeal laser resections in treatment of cancer of the voice box and recommend this technique for active use in daily practice of head and neck tumor specialists.

Introduction. The prevalence of oncological diseases of the oropharyngeal region continues to grow steadily, but there is an increase for a number of nosologies in the five-year survival rate of this category of patients, which naturally leads to the actualization of accompanying treatment programs and the desire to improve the quality of life of oncological patients. One of the areas of maintenance therapy in oncology is dental support, the choice of approaches and methods of which is not systematically organized.Aim. To determine the optimal method of dental support for patients with malignant neoplasms of the head and neck organs for the prevention and treatment of oral mucositis.Materials and methods. At the Russian Scientific Center of Roentgenoradiology, retrospective analysis of scientific clinical results of oral mycosis treatment in patients with malignant tumors of the head and neck receiving antitumor therapy was performed.Results. Two main approaches have been identified for the prevention and treatment of oral mucositis in patients with malignant neoplasms of the head and neck organs: personalized and unified approach. using personalized approach, maximal mean value of oral mycosis severity during the whole antitumor treatment period per the Radiation therapy Oncology group (RTOg) classification was 2.19 ± 0.13. The quality of life of patients is reduced by 26.1 %. using unified approach, maximal mean value of oral mycosis severity during the whole antitumor treatment period per the RTOg classification was 2.44 ± 0.05. The quality of life of patients is reduced by 51.5 %, but at the same time, absolutely all patients retain the ability to eat independently and take care of the oral cavity.Conclusion. Both personalized and unified approaches for the prevention and treatment of oral mucositis are possible for use in clinical practice.

Introduction. papillary thyroid cancer is increasingly being detected at early stages when regional and distant metastases are absent per clinical examination. However, lymph nodes of the central zone can carry hidden metastases. frequency of such metastases is 22.3–46.7 %. maximally accurate identification of hidden metastases after lymph node dissection remains an important problem.Aim. тo evaluate the effect of histological examination characteristics and immunohistochemical measurement of pancytokeratin level on frequency of detection of papillary cancer hidden metastases in regional lymph nodes of the central zone in patients with clinical stage N0 papillary cancer.Materials and methods. The main group included 50 patients with stage ст1–2N0М0 primary papillary thyroid cancer. Dissected central lymph nodes of the patients prior to formalin fixation were extracted from the sample and inserted in individual paraffin blocks. Apart from standard histological examination, pancytokeratin level was measured immunohistochemically in the lymph nodes. The control group consisted of 200 patients for whom dissected central cell tissue was sectioned into blocks after formalin fixation. The number of lymph nodes in the dissected sample was measured by a pathomorphologist.Results. In the main group, the number of lymph nodes in the sample varied between 6 and 37 with mean of 20.7 ± 6.8; in the control group the number was lower: 3–25, mean 9.8 ± 5.1 (р = 0.000). In the main group, hidden metastases were detected more frequently than in the control group: in 30 (60 %) and 68 (34 %) cases, respectively (р = 0.001). In 20 (40 %) patients, immunohistochemical examination showed new metastases. use of this method allowed to detect 1 to 7 additional metastases (mean 2.4 ± 1.5 lymph node lesions).Conclusion. use of targeted dissection with extraction of lymph nodes led to significant increase in their numbers in the samples, and immunohistochemical examination allowed to detect a large number of hidden metastases in the central lymph nodes.

Introduction. In recent times, changes in epidemiology of tongue cancer have been observed. morbidity among nonsmoking and non-abusing alcohol young women have been rising. Currently, etiology and pathogenesis of tumor development in this nosological group are unclear and require detailed analysis of epidemiologic and clinical data.Aim. To analyze the clinical material on the incidence of tongue cancer among young women (under 45 years old) over a 10-year period and assess the prevalence of this pathology in this group, the methods of treatment and reconstruction used, and determine the prognosis.Materials and methods. The study included 68 female patients with squamous cell carcinoma of the tongue who received treatment between 2010 and 2020. mean age was 36.8 years (between 18 and 45 years; median – 39 years). None of the patients had history of alcohol abuse or smoking. In 32 (47.1 %) patients, primary diagnosis was made at stages I–II, in 36 (52.9 %) at stages III–Iv.Results. In the last 10 years, a trend towards increased morbidity of tongue cancer among young women have been observed. In 2010, 2 cases of the disease were detected, in 2019–13, in 2020–14. mean follow-up duration was 40 months (median 32 months). Overall 5-year survival in this period was 72.5 ± 6.5 %, recurrence-free 5-years survival was 66.5 ± 6.6 %. Conclusion. Increase on tongue cancer morbidity among young non-smoking women is a new epidemiological trend worldwide. Etiological and pathogenetic factors of this trend have not been studied and require large multicenter studies for obtaining statistically significant results. Early medical resource utilization in this social group allows to perform adequate surgical intervention but requires the head and neck tumor specialist to pay attention to reconstructive surgery, quality and early patient rehabilitation allowing to preserve high quality of life, capacity for work and social activity.

Cutaneous squamous cell carcinoma accounts for 20 % of all malignant non-melanoma skin tumors, which is one of the most common cancers worldwide. Antitumor treatment is usually very effective: cure rate reaches 90 %, while local recurrence rate is 25 %. The main treatment option for primary skin cancers is surgery. The most significant risk factors for locoregional recurrence include tumor location (head and neck), size (>2 cm), depth of invasion (>4 mm), tumor differentiation grade, perineural invasion, immune system disorders (immunosuppression), severe concomitant diseases, and previous treatment.In patients with advanced cutaneous squamous cell carcinoma, 1-year, 2-year, and 3-year survival rates are 50–80, 30–35 and 15–16 %, respectively. Radiotherapy is a radical treatment option that increases the 5-year survival rate to 90 % and ensures good cosmetic results in 80 % of cases. There are 3 main variants of radiotherapy for cutaneous squamous cell carcinoma: sole radiotherapy according to a radical program, adjuvant radiotherapy in combination with surgery, and palliative radiotherapy. most frequently, radiotherapy is used as part of adjuvant postoperative treatment and is not initially considered as a sole conservative treatment for cutaneous squamous cell carcinoma patients below 45 years of age with resectable tumors, especially high-risk tumors. palliative radiotherapy is an affordable and effective method for combating painful symptoms; moreover, it often provides long-term local control.

Introduction. Thyroid cancer is one of the most common malignant neoplasms of the endocrine system. well-differentiated thyroid cancer constitutes about 90 % of all malignant tumors of the thyroid gland. Despite growing morbidity and high incidence of this pathology, in case of timely diagnosis and treatment well-differentiated thyroid cancer has favorable prognosis.Aim. using clinical examples, to demonstrate the possibility of thyroglobulin measurement in needle washouts of fineneedle aspiration biopsy in the detection of cervical metastases of highly differentiated thyroid cancer.Materials and methods. five patients (2 patients with combined oncological pathology, 2 patients with nodes in the thyroid gland, 1 patient after a thyroidectomy) with cervical adenopathy measured the level of thyroglobulin in the wash out fluid of lymph-nodes biopsy using the immunoradiometric method using the commercial kits of the Institute of Isotopes-IRmA (Hungary).Results. Cervical metastases of highly differentiated thyroid cancer were detected or excluded by the determination of fine-needle aspiration biopsy in patients with non-informational cytological studies. The determination of fineneedle aspiration biopsy is a useful diagnostic method in the differential diagnosis of cervical metastases in patients who have other morphological forms of cancer in addition to well-differentiated thyroid cancer, as well as for the differential diagnosis of cervical adenopathy in patients with a history of highly differentiated thyroid cancer.Conclusion. Determination of thyroglobulin level in puncture needle washout is a simple and useful diagnostic method for differential diagnosis of metastases in lymph nodes of the neck in patients with several morphological forms of malignant tumors.

The article presents a clinical case of atypical teratoid rhabdoid tumor with one of the longest catamnesis described in literature (109 months) and high quality of life. first, a giant tumor of the frontal lobe with advancement into a lateral ventricle was found in a female patient and totally removed. It was histologically diagnosed as primitive neuroectodermal tumor. Combination treatment consisting of radiotherapy, high-dose polychemotherapy and cellular immunotherapy including intrathecal therapy led to 4-year recurrence-free period. Recurrence of the tumor was resected. The period of the 2nd remission was 34 months. Subsequently, multistage metastasis of the tumor through cerebrospinal fluid tracts of the brain and spinal cord was observed. Twice microsurgical treatment with removal of symptomatic metastases in ventricles Iv and III was performed. In repeat morphological examinations, the tumor was verified as atypical teratoid rhabdoid tumor. The presented clinical case shows the role of active surgical tactics in effective long-term combination treatment of this severe pathology.

Introduction. Interactions between the 2 microbiota components – bacteria and fungi – are of interest as diagnostic and prognostic markers in selection of treatment tactics for oncological patients.Aim. To study microbiota of the oral cavity in patients with primary squamous cell carcinoma of the oropharyngeal area before and after surgical intervention to find biomarkers for rational selection of antifungal drugs.Materials and methods. At the Surgical Department of Head and Neck Tumors of the N. N. Blokhin National Research Center of Oncology, three-component study was performed: investigations of spectrum of Candida spp. isolates, Candida spp. strains’ resistance to antifungals, and oral washes in primary patients before and after surgery. mALDI-Tof microflex LT (Biotyper, Bruker Daltonics, germany) was used for strain identification; Sensititre Yeast ONE, YO10 (Trek Diagnostic System, united kingdom) plates were used for determination of minimal inhibiting concentrations of anti fungals. values of minimal inhibiting concentrations were evaluated based on the European Committee on Antimicrobial Susceptibility Testing (EuCAST) criteria (version 10.0).Results. four-year observation of patients at the surgical department of head and neck tumors of the N. N. Blokhin National Research Center of Oncology showed that the most common species of Candida is C. albicans (73.5 % of cases). Candida spp. resistance to antifungals was detected only for fluconazole (9.3 % of cases) and micafungin (8.0 % of cases), mostly among C. albicans strains. In 31.8 % of primary patients, oral washes prior to surgery showed growth of Candida spp. (probably, tissue colonization). After surgical intervention, Candida spp. growth was detected in 36.4 % of cases, only 1 of which was diagnosed as invasive mycosis. In 54.5 % of cases before and in 72.7 % of cases after surgery, gram-negative rods were detected. After surgical intervention, percentage of enterobacteria and non-fermenters significantly increased: 59.1 % versus 27.3 % (p <0.05) and 63.6 % versus 27.3 % (p <0.02), respectively. prior to surgery, non-fermenting gram-negative bacteria were represented only by P. aeruginosa; after surgery, the spectrum of non-fermenting gram-negative bacteria became wider but percentage of P. aeruginosa remained high: 71.4 %. ERG11 gene was identified only in 1 strain: C. albicans. FKS1 gene also was identified only in 1 strain: C. inconspicua. virulence factor genes were detected in 57.1 % of strains.Conclusion. Surgical intervention is associated with changes in bacterial microbiota but not fugal microbiota. presence of virulence factor genes and resistance genes in Candida spp. strains should be considered a biomarker allowing to differentiate between colonization and candida infection and can be used for rational selection of antifungal drugs in prevention and treatment of invasive candidiasis, especially in the absence of criteria for interpretation of measured minimal inhibitin
介绍。细菌和真菌这两种微生物群之间的相互作用是肿瘤患者选择治疗策略时的诊断和预后指标。目的研究原发性口咽区鳞状细胞癌患者手术干预前后口腔微生物群的变化，寻找生物标志物，为合理选择抗真菌药物提供依据。材料和方法。在N. N. Blokhin国家肿瘤研究中心头颈部肿瘤外科，对原发患者手术前后的念珠菌菌株谱、念珠菌菌株对抗真菌药物的耐药性和口腔洗液进行了三组分研究。mALDI-Tof microflex LT (Biotyper, Bruker Daltonics, germany)用于菌株鉴定;使用Sensititre Yeast ONE, YO10 (Trek诊断系统，英国)板测定抗真菌的最低抑制浓度。根据欧洲抗菌药物敏感性试验委员会(EuCAST)标准(10.0版)评估最小抑制浓度值。对N. N. Blokhin国家肿瘤研究中心头颈部肿瘤外科患者四年的观察表明，念珠菌最常见的种类是白色念珠菌(73.5%)。念珠菌仅对氟康唑(9.3%)和米卡芬宁(8.0%)耐药，以白色念珠菌为主。在31.8%的原发患者中，术前口腔清洗显示念珠菌生长(可能是组织定植)。手术干预后，36.4%的病例检出念珠菌生长，其中只有1例诊断为侵袭性真菌病。术前54.5%的病例和术后72.7%的病例检出革兰氏阴性杆状体。手术干预后，肠杆菌和非发酵菌的比例分别显著增加:59.1%比27.3% (p <0.05)和63.6%比27.3% (p <0.02)。手术前，非发酵革兰氏阴性菌仅为铜绿假单胞菌;手术后，非发酵革兰氏阴性菌谱变宽，但铜绿假单胞菌的比例仍然很高，为71.4%。ERG11基因仅在1株白色念珠菌中检测到。FKS1基因也只在1株C. inua中被鉴定出来。毒力因子基因检出率为57.1%。手术干预与细菌微生物群的变化有关，但与真菌微生物群无关。念珠菌菌株中毒力因子基因和耐药基因的存在应被视为区分定植和念珠菌感染的生物标志物，可用于合理选择抗真菌药物以预防和治疗侵袭性念珠菌病，特别是在缺乏抗真菌药物最低抑制浓度解释标准的情况下。

An obvious trend of the last decade in head and neck squamous cell carcinoma pathogenesis evaluation is awareness of the impact of immune response disorders on disease manifestation. The review presents an analysis of the differences in the type and degree of immunosuppression, as well as treatment response in head and neck squamous cell carcinoma patients in accordance with influencing carcinogenic factor, gender, age of the patient and concomitant diseases. An increase in CD8+ T-lymphocytes and a decrease of memory T-cells has been evaluated in smoking and alcohol abusing patients with head and neck squamous cell carcinoma, and a smaller number of CD8+ T-lymphocytes were detected in the tumor microenvironment compared to non-smoking and non-drinking patients. Studies have shown that the improved prognosis of patients with human papillomavirus (Hpv) – associated head and neck squamous cell carcinoma is largely due to the presence of antibodies against Hpv E6 and E7, E7-specific CD8+T lymphocytes in periphe ral blood and a high level of tumor-infiltrating T lymphocytes. The issue of gender differences in the type of immune response is widely discussed. It has been shown that the use of immune response checkpoint inhibitors is more effective in improving survival rates in men, and the use of these drugs in combination with chemotherapy is more effective in women. In addition, in elderly cancer patients, numerous age-associated T-lymphocyte’s function changes were revealed, including a decrease in the number of naive T-lymphocytes due to age-related involution of the thymus and an in crease in the relative number of memory cells and effector cells. Thus, it is clear that immunosuppression type, as well as treatment response, differ depending on the influencing factor, gender, age of the patient, as well as comorbidities.
