Rationale. In the early stages of classical Hodgkin’s lymphoma (cHL), the cure rate reaches 85–95 %, but the long-term effects of therapy can worsen overall survival. Current trials for early stages of Hodgkin’s lymphoma with favorable prognosis address the task of maintaining cure rates while reducing sequelae. For early unfavorable stages, the challenge is to improve cure rate without increasing toxicity.

Purpose. To assess the potential significance of individual risk factors for optimal choice of the first line chemotherapy in early-stage Hodgkin lymphoma.

Materials and methods. This single-center retrospective study included 290 patients with early stage cHL who had received ABVD – based (n = 249; 86 %) or BEACOPP‑21 – based (n = 41; 14 %) combined modality therapy from 2000 to 2017. Progression-free survival (PFS) and overall survival (OS) were assessed in Cox regression analysis including 12 clinical parameters.

Main results. At a median follow up of 60 months for the entire group, OS was 95 % and PFS was 89 %. In a multivariate analysis PFS, at 5 years, was significantly inferior in patients with mediastinal bulk, baseline lymphocytopenia (≤ 0.6 × 109/L, р = 0.002; < 1.0 × 109/L, р = 0.000) and male gender; OS was inferior only in patients with an absolute lymphocytopenia (AL). In patients with AL, PFS after ABVD-based regimen was, respectively, 12 % in the high-risk group with mediastinal bulk and 56 % without it. PFS of patients without AL when treated with ABVD did not differ compared to BEACOPP‑21 within the same prognostic group: 95.2 % vs. 92.3 % for non-bulky and 86.4 % vs. 84.2 % for bulky disease. In the absence of AL, mediastinal bulk remained the main and only risk factor in multivariate analysis.

Conclusions. The ABVD regimen is highly effective in the first line of chemotherapy for cHL, except for cases with baseline lymphocytopenia, in which the early usage of the BEACOPP regimen in the escalated or 14-day variants might be justified. In patients with mediastinal bulk, standard chemotherapy is not effective enough even in the absence of AL; therefore, if an intermediate PET/CT scan is available, it seems more appropriate to use a milder ABVD regimen on the first line and leave intensive therapy for patients with proven refractory disease. Prospects for improving the efficiency are opened with the new N-AVD and A-AVD schemes, the benefits of which should be evaluated, first of all, in patients with AL and mediastinal bulk.

Gorlin-Golts syndrome is a genetic determined disease, characterized by multisystem features and associated with different malignancies, which are more aggressive with very unfavorable prognosis. By literature data this syndrome is a rare pathology. Observation and treatment of patients with Gorlin-Golts syndrome include syndromic correction of clinical presentations and detailed observation for early malignancies detection. In the current issue a survey of modern literature about Gorlin-Golts syndrome in children and clinical case of patient sent to Federal State Budgetary Institution» N. N. Blokhin National Medical Research Center of Oncology «of the Ministry of Health for malignancy diagnosis are presented. By global and own clinical experience about Gorlin-Golts syndrome it is necessary a genetic verification and make us perform a multidisciplinary control for such patient health with obligatory examination and observation of pediatric oncologist.

Considering the fact that the group of neuroendocrine carcinomas (NECs) grade 3 is heterogenous, in the year of 2017 a new subgroup of welldifferentiated neuroendocrine tumors grade 3 (NETs G3) was described. NETs G3 are tumors with more favorable prognosis and less sensitive to platinum-based chemotherapy regimens than NECs, they also have peculiar morphogenetical qualities: lower ki‑67 index (mean 35.0 %), higher somatostatin receptors expression, absence of DAXX/ATRX/MEN 1 genes mutation, p53 expression in the absence of TP53 mutation. Nowadays treatment standard for NETs G3 subgroup is still remain unclear due to lack of prospective clinical trials. At the same time taking in note historical retrospective data, NETs G3 should be treated in line with NETs G1/G2 and only patients with higher ki‑67 index can be treated as NECs with platinum-based chemotherapy. In our non-randomised phase II prospective trial, we accessed the efficacy of different chemotherapy regimens in combination with somatostatin analogues in new NETs G3 subgroup. 153 patients with IHC-confirmed neuroendocrine neoplasm diagnose were included: NETs G3 n = 53 mean ki‑67 36.4 % [21.0–60.0 %], NETs G2 n = 50 mean ki‑67 15.7 % [2.1–20.0 %], NECs n = 50 mean ki‑67 69.0 % [38.0–96.0 %]). Patients from NETs G3 subgroup received 4 chemotherapy regimens: Aranose (n = 19), Aranose (arabinopiranosilmethyl nitrosocarbamide, ALK, – cytostatic drug with a chemical structure similar to Streptozotocin and Nitrosomethylurea, approved in Russian Federation for melanoma and welldifferentiated neuroendocrine tumors treatment), XELOX (n = 8), TemCAP (n = 11), EP/EC (n = 10). mPFS in Aranose-subgroup was 19.3 ± 5.9 months (95 % CI: 7.7–30.8), in XELOX – 10.8 ± 3.6 months (3.7–17.8), in TemCAP – 14.8 ± 4.2 months (6.6–23.1) and in platinum-based regimens – 4.4 ± 1.9 months (0.6–8.2) (p = 0.01). DCR in Aranose subgroup was 73.6 % and ORR – 36.8 %, PDR – 21.1 %, in XELOX subgroup ORR was 62.5 %, SDR was 50.0 % and PDR – 25.0 %, in TemCAP subgroup DCR was 63.6 %, ORR – 9.1 %, PDR – 18.2 % and in platinum-based regimens SDR was 40.0 %, PDR – 50.0 % (p = 0.05).

Medulloblastoma (MB) treatment in pediatric patients is an open challenge in clinical oncology. Current treatment protocols are risk-adopted and risk group criteria continuously evolve by increasing data about molecular and biologic mechanisms of MB tumorogenesis. In the current issue it is reviewed modern treatment programs, which became a basis of Russian and International clinical recommendations. It is analyzed treatment results according to regimens of chemotherapy and irradiation, absence or presence of metastases, histologic variant and molecular and biologic tumor features.

The aim of this study was to assess the safety and efficacy of treating patients with operable pancreatic cancer after preoperative intra-arterial infusion of chemotherapy combined with conformal radiation therapy in a multi-fractionation mode. Patients (n = 40) were randomized into two groups: the main one – intra-arterial infusion of chemotherapy + radiation therapy + surgery (n = 20), and control – intra-arterial infusion of chemotherapy + surgery (n = 20). Neoadjuvant therapy consisted of intra-arterial infusion of chemotherapy (chemoembolization of a pancreatic head tumor with oxaliplatin 85 mg/m2) followed by intra-arterial chemo infusion with gemcitabine 1000 mg/m2. In the main group, radiation therapy was also carried out in two fractions per day, 2 Gy with an interval of 4–6 hours, 5 days a week, up to a total dose of 50 Gy. In the main group, the lower incidence of postoperative pancreatitis and the pancreatic fistulas were statistically confirmed, the incidence of grade 2 therapeutic pathomorphisis increased, as well as the median life expectancy.

Objective. Analyze the frequency and prognostic factors of complications in patients with locally advanced cervical esophageal cancer after pharyngolaryngoesophagectomy with simultaneous reconstruction of the defect.

Material and methods. The retrospective study included patients with a verified locally advanced cervical esophageal cancer who were treated at the N. N. Petrov National Research Institute of Oncology in the period from 2009 to 2018, who underwent surgical treatment followed by chemoradiotherapy. The end point of the study was the frequency of postoperative complications.

Results. Forty-eight patients were included in the study. All patients underwent laryngopharyngoesophagectomy with simultaneous reconstruction of the digestive tract. Forty-one patients (85.4 %) underwent the reconstructive stage using a narrow gastric stalk, and a wide gastric stalk and a small intestine graft were used in 5 (10.4 %) and 2 (4.2 %) patients, respectively. The average duration of the operation was 390 (337.5–525.0) minutes, the volume of blood loss was 300 (200–500) ml, and the average time of hospitalization and the patient’s stay in the intensive care unit was 21.5 (16.00–36.00) and 3 (1.000–6.75) days, respectively. Complications within 30 days after surgical treatment were observed in 54.1 % of patients, while anastomosis failure, fistula formation and pneumonia were observed in 22.9 %, 12.5 % and 18.8 % of cases, respectively. Factors slightly increasing the likelihood of pneumonia in the early postoperative period were: duration of surgery [OR = 1.0 (95 % CI: 1.00–1.01), p = 0.0131] and intraoperative blood loss [OR = 1.0 (95 % CI: 1.00–1.01), p = 0.0017].

Conclusion. The overall complication rate after pharyngolaryngoesophagectomy with simultaneous repair of the defect by bioengineered graft was 54.1 %. Intraoperative blood loss and duration of surgery were associated with an increased risk of complications.
