Parasternal mediastinotomy is a surgical method of morphological verification of mediastinal tumors, widely performed in oncological clinics. The article provides information about the method of implementation and the results of parasternal mediastinotomy for malignant tumors of the mediastinum.Purpose of the study. Evaluation of the results of parasternal mediastinotomy for morphological verification of mediastinal tumors.Patients and methods. The study included 77 patients who for the period from 2008 to 2018. 80 parasternal mediastinotomies were performed with a biopsy of a mediastinal tumor in the conditions of the Department of Thoracic Surgery of the P. Hertsen Moscow Oncology Research Institute. At the stage of preoperative examination, all patients underwent standard diagnostic studies: computed tomography of the chest, abdominal cavity, and a comprehensive ultrasound. In the case of the presence of the endobronchial component of the tumor, fibrobronchoscopy was performed. MRI of the brain was performed in patients with neurological symptoms. 12-lead ECG, echocardiography, and a study of the function of external respiration were performed to assess the functional status of patients.Results. The final histological diagnosis was made in 76 of 77 (99%) patients. The clinical diagnosis of lymphoma was set in 66, thymoma — in 6 patients, lung cancer with affection of mediastinal lymph nodes — in 4 patients, mediastinal tumor — in 4 patients. In 24 patients (31%), operations were preceded by other attempts at morphological verification. In 12 patients — mediastinal tumor biopsy under ultrasound control, in 3 — parasternal mediastinotomy, in 2 — transthoracic mediastinal tumor biopsy combined with biopsy of supraclavicular lymph node under ultrasound control, 2 — biopsy of supraclavicular lymph node under ultrasound control, in 1 — mediastinum tumor biopsy under control. — chest wall biopsy, in 1 — open biopsy with thoracotomic access, in 1 — tonsil biopsy, in 1 — trachea biopsy. In all cases, the indication for performing a parasternal mediastinotomy was an insufficient amount of material for carrying out a complete immunohistochemical study.Conclusion. Parasternal mediastinotomy is a safe and reliable method of morphological verification of the formations of the anterior mediastinum and para-aortic region. In case of the ineffectiveness of transthoracic biopsy under the control of ultrasound or CT navigation, the performing of parasternal mediastinotomy allows to establish a morphological diagnosis and to begin a specific treatment in the shortest possible time.

Surgical treatment of patients with tumoral defeat of pelvic bones, of preacetabular region, in particular, is one of the most challenging topics of modern oncorthopedics. Currently, one of the most modern methods of reconstruction of the pelvic bones is the use of modular endoprostheses based on the conical leg, the advantage of which is the ability to intraoperatively simulate an endoprosthesis that best meets the specific clinical situation. Purpose of research. To assess the benefits of modular endoprosthesis of the acetabulum in patients with tumoral defeat periacetabular region.Patients and methods. Within the period of 2011–2018 30 patients underwent surgical treatment in form of periacetabular resection with a modular endoprosthesis reconstruction in P.Hertsen Moscow Oncology Research Institute – Branch of National Medical Research Radiological Centre of Ministry of Health of Russian Federation. There were 13 men (43%) and 17 women (57%). The median age was 45 years (23–63 years). Primary bone cancers were in 19 (63%) patients, giant cell tumors in 5 (17%), locally advanced soft tissue sarcoma in 1 (3%), solitary metastases of kidney cancer in 2 (7%), and recurrent sarcomas after previous surgical treatment in 3 (10%) patients.Results. The average duration of the operation was 310 min (145–520 min), the volume of intraoperative blood loss was 5520 ml (600–20 000 ml). The positive edge of resection according to the results of the planned morphological study was revealed in 3 (10%) patients. The average follow-up period was 36 months (4-73 months). Disease progression in terms of 6 to 40 months was revealed in 10 (33%) patients. 8 (27%) patients from disease progression. Complications of different types were diagnosed in 11 (37%) patients, among whom infectious complications prevailed 9 (30%). The average value of the functional results on a scale MSTS accounted for 59% (15 to 82%). Conclusion. The use of modular systems of endoprosthesis replacement of the acetabulum and hip joint in tumor lesions is a promising surgical technique that allows to achieve adequate functional results with a comparable number of postoperative complications.

Purpose.To analyze the main medical and statistical parameters, allowing to evaluate the results of breast cancer treatment.Patients and methods.Data on 4689 breast cancer (BC) patients were analyzed retrospectively. Inclusion criteria were: female, residence in St. Petersburg, diagnosis of BC established in 2011, 2012. The study also includes information on the options of BC surgical treatment, one-year mortality in breast cancer patients and index of the contingent accumulation in St. Petersburg in 2011–2017. For statistical data processing Statistica 12.0 for Windows, Population Cancer Register and MedInfo-4 were used. The differences in the groups of studies were considered statistically significant at p < 0.05.Results.The prevalence of breast cancer among women in St. Petersburg varies from 532.6 per 100 000 population in 2011 to 545.00/0000 in 2012. In 2011 the incidence of BC in women in St. Petersburg was 46.210/0000 (standard deviation 1.05) and in 2012 – 49.50/0000 (standard deviation 1.05). The mean age of breast cancer patients is 64 years (standard deviation 12.25). Localization of a tumor in one of the glands was found in 4617 (98.5%) clinical observations. In 2,846 (60.7%) cases, the tumor sizes varied from 2 to 5 cm. Signs of infiltrative ductal carcinoma were histologically verified in 3689 (80%) cases. The proportion of single-stage breast reconstruction after mastectomy in the overall structure of surgeries in breast cancer patients increased in 2011–2017 more than 6.5 times. The 5-year survival rate in study groups was 64.4% and 63.3%.ConclusionsThe main statistical parameters of medical care (MC) analysis in breast cancer patients in St. Petersburg in 2011–2017 allow to state generally positive trends in the anticancer fight organization. The increase of the breast cancer incidence rates is partly due to the improved quality of examination and treatment of patients through the creation in the city of a system of high-tech MC, as well as to the particularly wary of doctors in detecting breast tumors.

Published: June 2019

Background. In 2016, the World Health Organization published an updated version of the Histological Classification for ovarian tumors presenting a new category of endometriosis-associated tumors. The predictors of malignant transformation of endometriosis have not been clearly defined so far.Purpose. The search for histological and immunohistochemical markers of endometriosis-associated malignancy.Materials and methods. 28 female patients with endometrioid ovarian cancer and 11 patients with clear cell ovarian carcinoma were enrolled. Histological and immunohistochemical studies were carried out using conventional techniques. Immunohistochemistry was applied to determine the hormone receptor status: expression of steroid hormone receptors, BAF250a (ARID1A), PTEN, P-catenin, MSH6, PMS2, р-53, WT-1, proliferative index (Ki-67). Microsatellite instability (MSI) testing was conducted according to the standard protocol.Results. In all cases of ovarian cancer, histological examination showed one of the endometriosis features. Atypical endometriosis was found in 39 % (11 / 28) of endometrioid tumors and in 9% (1/ 11) of clear cell carcinomas. Endometrioid ovarian cancer was found to be ER (74±7,8%) — and PR (67±5,4%) — positive; Ki-67 index was 68,2±3,7 %; loss of BAF250a (ARID1A) expression was observed in 14% (4/ 28), loss of PTEN expression in 29 % (8 / 28), nuclear expression of P-catenin in 32% (9/28) of cases. Loss of MMR expression was detected in 7% (2/28) of cases. MSI was found in one case only, which was also associated with loss of expression of BAF250a (ARID1A) and MSH6. Clear cell carcinoma of the ovary showed histological criteria for endometriosis; however, there were no changes immunohistochemical markers expression that were typical for endometriosis-associated malignancies. It could be due to a small number of patients in the group so further research is needed.Conclusion. Atypical endometriosis may be a morphological precursor of endometrioid and clear cell carcinoma of the ovary. Comprehensive assessment of a marker panel consisting of BAF250a (ARID1A), P-catenin, PTEN, p53, Ki-67 index, PMS2 and MSH6 will allow improving the diagnosis of atypical endometriosis and endometriosis-associated ovarian cancer.

Published: June 2019

Background. Locally advanced squamous cell carcinoma of the oral cavity invades the mandible in 13–38 % of cases. Even a small segmental resection of the mandible, for instance, in the chin area, causes significant functional and cosmetic impairment and requires immediate reconstruction of the bone defect. Currently available methods of defect closure require a comparative assessment.Materials and methods. This article is based on the outcome data from patients with mandibular tumors treated from 1998 through 2018. We identified 471 cases of mandibular surgery including marginal resection and midline mandibulotomy; 203 (43.1 %) patients underwent segmental resection. Of them, we selected 99 patients with an isolated chin defect combined either with a mandibular body defect or with a subtotal defect in the mandible.Results. In this study, we analyzed the treatment outcomes in patients with primary and secondary mandibular tumors involving the chin as the most difficult for reconstruction from the point of view of the surgeon and the most important for the patient from the functional and aesthetic point of view.Conclusions. A mandibular defect located in the chin area requires immediate reconstruction. The preferable method of defect closure is the application of a reconstruction plate with a musculocutaneous flap or implantation of vascularized bone grafts. Implantation of a fibular free flap is preferable for the closure of extensive mandibular defects involving the chin area.
