Consensus guideline for the management of patients with appendiceal tumors: Part 2: Appendiceal tumors with peritoneal involvement

Abstract

Background Appendiceal tumors comprise a heterogeneous group of tumors which frequently disseminate to the peritoneum. Management of appendiceal tumors is lacking high quality data, given its rarity and heterogeneity. In general, appendiceal tumor treatment is extrapolated in part from colorectal cancer or pooled studies, without definitive evidence of disease-specific benefit. Many practices are controversial and vary widely between institutions. A national consensus update of best management practices for appendiceal malignancies was performed to better standardize care. Herein we present recommendations for management of appendiceal tumors with peritoneal involvement.
