Does the literature support an indication for hepatic metastasectomy other than for colorectal primary

Hepatic resection for colorectal hepatic metastatic disease has been demonstrated to have a significant outcome benefit for selected patients. Advances in anesthetic and surgical technique have resulted in a significantly reduced morbidity and mortality for this procedure, and this management approach has become widely practiced. This hepatic resection paradigm is also being applied to hepatic metastatic disease of noncolorectal origin. The purpose of this report is to review and summarize the reported literature in order to define if the current data support an indication for hepatic metastasectomy. Thespecific cancer primaries that this analysis evaluated include breast, melanoma, gynecologic, neuroendocrine, sarcoma, and gastric cancer. Based on the data examined, we propose that although hepatic metastasectomy for noncolorectal cancer may be a promising component of overall oncologic treatment, the role of surgical resection cannot be generalized and at present should be individualized based on the patient’s clinical course and by the biologic behaviors of specific malignancies.

Comparative analysis of resected duodenal and ampullary adenocarcinoma.

362 Background: Duodenal and ampullary adenocarcinomas are rare gastrointestinal cancers that share similar anatomic location and treatment strategy. We report a single-institution experience regarding the association between clinicopathologic features, treatment, and survival outcomes. Methods: A retrospective review of all patients resected with curative intent for duodenal adenocarcinoma (DUO) between 2005-2015 and ampullary adenocarcinoma (AMP) between 2011-2015 at VMMC was performed. For AMP, histologic subtyping into intestinal (IT) and pancreatobiliary (PB) phenotypes was determined. Demographic and clinicopathologic parameters were compared between DUO and AMP patients using Chi-square test. Overall survival was calculated using Kaplan-Meier analysis and prognostic factors were identified by univariate Cox regression. Results: Patients with DUO (n = 44) presented at higher T-stage (p = 0.002) and with larger tumors (4.35cm vs 2.33cm, p < 0.001) than AMP patients (n = 46). DUO patients had a higher...
