description •-Management of metastatic rectal adenocarcinoma is multidisciplinary and complex.•-Induction triplet chemotherapy is effective on primary site and metastases.•-Induction chemotherapy is associated with a high rate of objective response rate.•Metastases resection allows for prolonged survival.•Prognostic value of KRAS/BRAF mutations appears similar for rectal and colon cancers. The management of synchronous metastatic rectal cancer (SMRC) is complex and multimodal, involving chemotherapy, surgery and/or radiotherapy. The aim of this study was firstly to confirm the efficacy of the induction FOLFIRINOX, and secondly to evaluate the different therapeutic strategies and outcomes of patients. This French study combined data from a prospective FFCD trial and a multicenter cohort. Patients included had SMRC and had undergone induction triplet chemotherapy. Two groups of patients were defined according to the resectability of metastases at baseline: resectable (Res) and unresectable (URes). The primary endpoint was the objective response rate. 146 patients were included in 16 French centers and 65 patients in the FFCD1102 trial. In overall population the median age of patients was 59 years, 86% of tumors were of the lower or middle rectum, 33% were well-differentiated, 53% were RAS mutated and 7% BRAF mutated. Triplet induction was associated with 80% of objective response and 92% of disease control. After the induction phase, 69% and 48% of patients of Res and URes groups underwent rectal surgery, and secondary metastases resection was done in 79% and 39% of patients, respectively. Median overall survival (OS) for Res was 56.3 months (95% CI: 22.54-NA). Median OS for URes who had or not secondary metastases resection were 45.1 months (95% CI: 39.89-NA) and 21.1 months (95% CI 17.31–27.1), respectively. Patients with BRAF mutated tumors were more likely to have unresectable disease, and had worse survivals than the patients with RAS mutated or RAS/BRAF wild-type.
