Background Hepatic metastases are a major cause of death in patients with colorectal cancer. A comprehensive assessment of the prognostic factors associated with long‐term survival could improve patient selection for surgical approaches and decrease morbidity and futile locoregional treatments. Methods We performed a retrospective analysis of patients who underwent hepatectomy for colorectal liver metastases at a single center from 2000 to 2012. Results To identify factors associated with 5‐ and 10‐year overall (OS) and disease‐free survival (DFS), we analyzed 280 patients and 150 patients in the 5‐ and 10‐year cohorts, respectively. Only seven relapses occurred after 5 years of follow‐up, and no relapses occurred after 10 years. Multivariable analysis indicated that bilobar disease and extra‐hepatic disease before hepatectomy were independent 5‐ and 10‐year predictors of OS, and major postoperative complications predicted OS in the 5‐year survival cohort only. Our analysis indicated that prognostic factors associated with DFS included some confounders and was therefore inconclusive. Conclusions Taken together, our results suggest that the predictors of 5‐ and 10‐year OS rates of colorectal cancer patients with hepatic metastases are similar, differing only by postoperative complications that influenced exclusively 5‐year survival. Since no relapse occurred 10 years after hepatic resection, oncological remission is likely.

Background and Objectives: Incidence of pancreatic neuroendocrine tumors (pNETS) seems to be rising over the years, with many cases incidentally diagnosed.Surgery and active surveillance are current treatment modalities for small pNETS.We review our institutional series and compare outcomes for small asymptomatic and nonfunctioning tumors.Methods: This retrospective cohort study included patients with 2 cm or less and well differentiated pNETS at a single Brazilian Cancer Center. From 2002 to 2020, patients received active surveillance or surgery as a treatment strategy. Short and long-term results were compared.Results: Sixty-four patients were included, 41 in surgical strategy and 23 in the active surveillance approach. Baseline group characteristics were comparable. More patients on active surveillance underwent abdominal magnetic resonance imaging (MRI) and had tumors located in the pancreatic head (41% vs. 17%, p = 0.038).Minimally invasive procedure was chosen in 80.1% of the surgical patients. No patient died after surgery. Median follow-up period was 38.6 and 46.4 months for active surveillance and surgery cohorts, respectively. No difference in disease progression rate was observed. Conclusion:Both approaches seem to be safe for small pNETs. Long-term outcome and quality of life should be considered when discussing such options with patients.
