    Introduction. Trifluridine/Tipiracil (FTD/TPI) is a new chemotherapeutic drug approved in more than 60 countries for use in patients with metastatic colorectal cancer who have registered progression or intolerance to treatment with fluoropyrimi-dines, oxaliplatin and irinotecan, anti-VEGR-and anti-EGFR-targeted agents. This study evaluated for the first time the effectiveness and tolerability of FTD/TPI therapy in the Russian patient population. Materials and methods. A confirmatory open-label single-arm non-randomized trial was conducted in 2 clinical centres in Russia. The main criteria for inclusion were: conduction of at least the 2nd line of standard systemic therapy for metastatic colon adenocarcinoma. The primary efficacy criteria were: 2-month progression-free survival; secondary – median progression-free survival, disease control frequency, safety assessment, overall survival. Research number: NCT03274882. Results. A total of 26 patients were included in the study; the median age was 60.5 years (30 to 78); 19 (73%) women; and 4 patients with ECOG 0 and 22 – with ECOG 1. All patients were previously treated with the inclusion of oxaliplatin, irinotecan, fluoropyrimidines, 21 (81%) – bevacizumab, 6 (23%) – anti-EGFR antibodies, and 2 (7.7%) – regorafenib. The median for treatment courses was 4 (1–21), 11 (42.3%) patients were treated for 6 months or more. The two-month progression-free survival rate was 52% with a median progreesion-free survival rate of 4 months (95% CI 1.8–7.4 months). The median of total survival rate was 11 months (95% CI 5,2–16,8 months). Disease control was achieved in 60%. Neutropenia, nausea, vomiting, anemia, weakness prevailed among undesirable events associated with treatment (β‰₯5 patients). The majority of complications were of the 1st–2nd degree. Among the undesirable events of the 3rd–4th degree, neutropenia was more common, while in 3 patients febrile neutropenia of the 3rd degree was registered. Conclusions. In the Russian population of patients with colorectal chemorefractory cancer, the drug FTD/TPI (TAS-102) shows efficacy and tolerability comparable to the RECOURSE registration study.

    Rationale: Non-small cell lung cancer (NSCLC) is an aggressive disease with median survival of 1214 months in inoperable patients in the pre-immunotherapy era. Nowadays, under treatment with checkpoint inhibitors median survival is 1922 months. However, only a proportion of patients are sensitive to immune therapy. In this regard, inclusion into clinical trials remains a priority option for patients from medical perspective. Aim: To compare the results in NSCLC patients treated in accordance with the current clinical guidelines and in international clinical trials using the propensity score matching. Materials and methods: The study included data from 344 patients with histologically verified unresectable advanced NSCLC without activating mutations, who received the 1st line systemic medical therapy at various combinations (single agent chemotherapy, platinum doublet-based therapy, chemoimmunotherapy, single agent immunotherapy) within the compulsory health insurance (CHI), and from 90 patients, who received therapy in clinical trials. A direct comparison of long-term treatment results was carried out with the log-rank method. To exclude any influence of individual factors on survival rates, an univariate regression analysis and pseudorandomization accounting for these factors were carried out. Results: The direct comparison of the treatment results showed a higher progression-free survival rate in the patients treated according to clinical trial protocols, than in those treated under CHI (13.3 [95% confidence interval (CI) 8.118.5] months vs 6.4 [95% CI 5.96.9] months). Pseudorandomization of patients based on a combination of statistically significant parameters from the CHI and clinical trial groups showed a significantly longer time to progression in the trial group (13.3 [95% CI 8.318.3] vs 6.3 [95% CI 4.87.7] months). Conclusion: Participation in clinical trials is per se a factor that can significantly impact the longer duration of the treatment effect. This indicates the necessity of the most active use of this tool in clinical practice.ΠΠΊΡ‚ΡƒΠ°Π»ΡŒΠ½ΠΎΡΡ‚ΡŒ.
