Popis: Aim. To evaluate the efficacy and toxicity of second-line polychemotherapy according to FOLFOX or FOLFIRI regimen in patients with biliary tract tumours after progression during first-line chemotherapy (CT). Materials and methods. The study is based on the analysis of retrospective and prospective data on the examination and treatment of 94 patients with biliary cancer of grades T1-4N0-2M0-1 followed-up and treated at the N.N. Blokhin National Medical Research Center of Oncology from 2015 to 2023. All patients were divided into 2 groups: Group 1 (FOLFOX, n=47) and Group 2 (FOLFIRI, n=47). In Group 1, patients received the recommended FOLFOX second-line CT regimen. Patients in Group 2 received FOLFIRI regimen. The endpoints were overall survival (OS) and incidence of grade 3-4 adverse events. Results. The study included 94 patients. In the FOLFOX group, the median OS was 13.0 months (1-year OS was 57.8±7.4%); for the FOLFIRI group, the median OS was 12.3 months (1-year OS was 54.4±7.3%). The toxicity profiles of FOLFOX and FOLFIRI were acceptable and consistent with those reported for the regimens. According to the grade 3–4 toxicity data, diarrhea was significantly more common in the FOLFIRI group (p=0.014), and neurotoxicity was more common in the FOLFOX group (p=0.006). During the second-line CT, the frequency of grade 1–4 toxicities in the groups did not differ: 18 (38.3%) events in the FOLFOX group and 19 (40.0%) events in the FOLFIRI group. Conclusion. Our results of evaluating the efficacy and toxicity of the second-line polychemotherapy regimens show that the FOLFOX and FOLFIRI CT regimens have equal efficacy in patients with advanced biliary tract cancer with a good performance according to the ECOG scale, who previously received the first-line therapy with a combination of gemcitabine with a platinum agent (cisplatin or oxaliplatin); also, our data demonstrate similar toxicity profiles of these regimens.
