Purpose. Control of pain syndrome in patients with locally advanced and recurrent pancreatic cancer using stereotactic radiation therapy (SBRT). Materials and methods. Our clinical observations relate to 103 patients with locally advanced (LAPC)and recurrent pancreatic cancer who received radiation therapy in the radiological unit of the NIITs NMI. NN Blokhin "in the periods: 2000-2010. and 2010-2015. The first group consisted of 77 patients with locally advanced non-resectable pancreatic cancer, of which (1a subgroup), 30 patients received radiotherapy in a classical fractionation regimen of  54-60 Gy/5 fraction, 40 patients (1b subgroup) in a mode of hypofractionation. per week  37.5 Gy/5 fraction. Group 2: 26 patients with recurrent pancreatic cancer, including 15 patients (2a subgroup), radiation therapy was performed in the classical fractionation regimen of 54-60 Gy/5 fraction, 11 patients (2b subgroup) underwent a course of radiation therapy in the mode of hypofractionation. Gr 5 times a week  37.5 Gy/5 fraction. Results. In SBRT, in 70% of cases, there was a reduction of all types of pain syndrome compared to 37.8% in the control group. The conclusion. Stereotactic beam therapy in the mode of hypofractionation is a highly effective, safe method of radiotherapy that effectively reduces pain syndrome in unresectable pancreatic cancer in a short time of treatment in comparison with the traditional method of radiotherapy, which significantly improves the quality of life of this severe category of patients.

Purpose To provide evidence-based recommendations to oncologists and others for treatment of patients with locally advanced, unresectable pancreatic cancer. Methods American Society of Clinical Oncology convened an Expert Panel of medical oncology, radiation oncology, surgical oncology, gastroenterology, palliative care, and advocacy experts and conducted a systematic review of the literature from January 2002 to June 2015. Outcomes included overall survival, disease-free survival, progression-free survival, and adverse events. Results Twenty-six randomized controlled trials met the systematic review criteria. Recommendations A multiphase computed tomography scan of the chest, abdomen, and pelvis should be performed. Baseline performance status and comorbidity profile should be evaluated. The goals of care, patient preferences, psychological status, support systems, and symptoms should guide decisions for treatments. A palliative care referral should occur at first visit. Initial systemic chemotherapy (6 months) with a combination regimen is recommended for most patients (for some patients radiation therapy may be offered up front) with Eastern Cooperative Oncology Group performance status 0 or 1 and a favorable comorbidity profile. There is no clear evidence to support one regimen over another. The gemcitabine-based combinations and treatments recommended in the metastatic setting (eg, fluorouracil, leucovorin, irinotecan, and oxaliplatin and gemcitabine plus nanoparticle albumin-bound paclitaxel) have not been evaluated in randomized controlled trials involving locally advanced, unresectable pancreatic cancer. If there is local disease progression after induction chemotherapy, without metastasis, then radiation therapy or stereotactic body radiotherapy may be offered also with an Eastern Cooperative Oncology Group performance status ≤ 2 and an adequate comorbidity profile. If there is stable disease after 6 months of induction chemotherapy but unacceptable toxicities, radiation therapy may be offered as an alternative. Patients with disease progression should be offered treatment per the ASCO Metastatic Pancreatic Cancer Treatment Guideline. Follow-up visits every 3 to 4 months are recommended.

e14025 Background: The effectiveness of radiation therapy in the classical and stereotactic treatment regimens of the primary glioblastoma multiforme was analyzed and compared. Methods: 87 patients with primary glioblastoma multiforme were hospitalized during the study period. 17 patients of them were in the treatment group (stereotactic radiotherapy, dose per fraction 2 Gy, 60 Gy total dose, CTV 2.0 cm, PTV 0.1 cm - group 1), and 70 patients were in the control group (conventionally fractionated radiotherapy, dose per fraction 2 Gy, 60 Gy total dose, CTV 2.0 cm, PTV 0.5 cm - group 2). Patients of both groups were treated with alkylating agents as the third stage of complex treatment. MGMT methylation was evaluated by pyrosequencing. Results: The use of stereotactic radiation therapy allowed to conduct a full course of treatment without interruption, whereas in the second group, due to the development of adverse reactions, the course was interrupted for 7 patients (10%). The advantage of stereotactic radiation therapy was a less pronounced increase and rapid regression of neurological deficits during treatment, manifested by better local control for 6 months. Hypermethylation of MGMT was detected in 39% of glioblastoma cases and was not detected in non-tumor tissue. The presence of promoter methylation disrupts DNA repair and is associated with longer survival in glioblastoma patients receiving alkylating agents. Note that the median survival of patients with MGMT hypermethylation in the group 1 was 285 days (IQR = 323.75), and in the group without hypermethylation was significantly more than 338.5 days (IQR = 476) (p = 0.045). A similar trend was observed in the second group: in patients with hypermethylated MGMT, the median survival was 271 days (IQR = 337), the result is different from patients without hypermethylated MGMT – 342 days (IQR = 493) (p = 0.039). Conclusions: As a result, the application of the stereotactic approach of radiation therapy in the complex treatment of patients with glioblastoma and their classification by the MGMT methylation status with a cut-off point of 10% has the basis for improving the effectiveness and tolerability of radiation therapy and contributes to the overall survival of patients.
