Introduction. The addition of durvalumab after chemoradiation therapy in unresectable stage III non-small-cell lung cancer (NSLC) is a new standard of care.Aim. Study the features and outcomes of durvalumab maintenance treatment after chemoradiotherapy in patients with unresectable stage III NSCLC in the real-world clinical practice in Russia.Materials and methods. 50 patients with unresectable III stage NSCLC after concurrent or sequential chemoradiotherapy (CRT) were enrolled in this observational retrospective study. Median follow up time at primary analysis was 12.4 months.Results. A mean age of the patients in the study was 61.2 years (58.4-64.1; 95% CI). Most of the patients had received sequential CRT (76%, n = 38). Median time of durvalumab start from the end of CRT varied from 22 to 50 days (overall - 35 days). Estimated median PFS and OS were 10.86 months (7.78-14.01, 95% CI) and 26 months (20.19-31.81, 95% CI), respectively. There was a trend toward increased PFS in patients with smoking history: 12 months (9.79-14.2; 95% CI) versus 4,9 months (0.0-12.47; 95% CI), p = 0.2. Half of the patients without smoking history (5/10) had targetable mutations (EGFR ex 19, ALK, ROS1, cMET). Most common reported adverse events of special interest were pneumonitis grade 1-2 (36%, n = 18), leading permanent treatment discontinuation to in 6% of patients (n = 3). There were no reported cases of grade 3-4 adverse events.Conclusions. Real-world characteristic of patients in our study were different from PACIFIC trial. Sequential CRT is the most frequent treatment option in locally advanced unresectable NSCLC in Russia. Estimated PFS was shorter than in PACIFIC, but there were less cases of pneumonitis.

This article is a literature review of the available data on the history of origin, mechanism of action, and the main currently available conjugate-linked monoclonal antibodies. The use of conjugate-linked monoclonal antibodies in the therapy of both solid and hematological malignancies is a promising direction of anti-tumor therapy.

Purpose of the study. There is the generalized analysis of administration of vinflunine in real clinical practice in St.Petersburg Clinical Scientific and Practical Center of Specialized medical Care (oncological).Materials and methods. This analysis gathered 27 patients with urothelial carcinoma treated using this medicine in St.Petersburg Clinical Scientific and Practical Center of Specialized medical Care (oncological). We assessed efficacy, safety profile of vinflunine in this subset of patients.Results. Clinical efficacy of vinflunine (complete response + partial response + stable disease) was 51,86 %, one patient demonstrated complete response. Median of response duration accounts for 3,4 months. Adverse events were observed in 28,4 %, most of them were 1-2 grades. 2 patients stopped therapy due to adverse events.Conclusion. In our analysis vinflunine was more effective than in randomized clinical trial and other studies from real practice in Europe. Thus, confirm expediency to administer of vinflunine for metastatic urothelial carcinoma.
