-Context -Liver metastases are a common event in the clinical outcome of patients with colorectal cancer and account for 2/3 of deaths from this disease. There is considerable controversy among the data in the literature regarding the results of surgical treatment and prognostic factors of survival, and no analysis have been done in a large cohort of patients in Brazil. Objectives -To characterize the results of surgical treatment of patients with colorectal liver metastases, and to establish prognostic factors of survival in a Brazilian population. Method -This was a retrospective study of patients undergoing liver resection for colorectal metastases in a tertiary cancer hospital from 1998 to 2009. We analyzed epidemiologic variables and the clinical characteristics of primary tumors, metastatic disease and its treatment, surgical procedures and follow-up, and survival results. Survival analyzes were done by the Kaplan-Meier method and the log-rank test was applied to determine the influence of variables on overall and disease-free survival. All variables associated with survival with P<0.20 in univariate analysis, were included in multivariate analysis using a Cox proportional hazard regression model. Results -During the period analyzed, 209 procedures were performed on 170 patients. Postoperative mortality in 90 days was 2.9% and 5-year overall survival was 64.9%. Its independent prognostic factors were the presence of extrahepatic disease at diagnosis of liver metastases, bilateral nodules and the occurrence of major complications after liver surgery. The estimated 5-year disease-free survival was 39.1% and its prognostic factors included R1 resection, extrahepatic disease, bilateral nodules, lymph node involvement in the primary tumor and primary tumors located in the rectum. Conclusion -Liver resection for colorectal metastases is safe and effective and the analysis of prognostic factors of survival in a large cohort of Brazilian patients showed similar results to those pointed in international series. The occurrence of major postoperative complications appears to be able to compromise overall survival and further investigation in needed in this topic. HEADINGS -Colorectal neoplasm.

Background: Liver metastases of colorectal cancer are frequent and potentially fatal event in the evolution of patients with these tumors. Aim: In this module, was contextualized the clinical situations and parameterized epidemiological data and results of the various treatment modalities established. Method: Was realized deep discussion on detecting and staging metastatic colorectal cancer, as well as employment of imaging methods in the evaluation of response to instituted systemic therapy. Results: The next step was based on the definition of which patients would have their metastases considered resectable and how to expand the amount of patients elegible for modalities with curative intent. Conclusion: Were presented clinical, pathological and molecular prognostic factors, validated to be taken into account in clinical practice.
Objective: to suggest a script for surgical oncology assistance in COVID-19 pandemic in Brazil. Method: a narrative review and a “brainstorming” consensus were carried out after discussion with more than 350 Brazilian specialists and renowned surgeons from Portugal, France, Italy and United States of America. Results: consensus on testing for COVID-19: 1- All patients to be operated should be tested between 24 and 48 before the procedure; 2- The team that has contact with sick or symptomatic patients should be tested; 3 - Chest tomography was suggested to investigate pulmonary changes. Consensus on protection of care teams: 1 - Use of surgical masks inside the hospitals. Use of N95 masks for all professionals in the operating room; 2 - Selection of cases for minimally invasive surgery and maximum pneumoperitoneal aspiration before removal of the surgical specimen; 2 - Optimization of the number of people in teams, with a minimum number of professionals, reducing their occupational exposure, the consumption of protective equipment and the circulation of people in the hospital environment; 3 - Isolation of contaminated patients. Priority consensus: 1- Construction of service priorities; 2 - Interdisciplinary discussion on minimally invasive or conventional pathways. Conclusion: the Brazilian Society of Surgical Oncology (BSSO) suggests a script for coping with oncological treatment, remembering that the impoundment in the assistance of these cases, can configure a new wave of overload in health systems.
