Background Appendiceal epithelial neoplasms are rare cancers. Management of peritoneal disease from appendiceal neoplasms has historically been with debulking surgery. In recent decades, the advent of cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) has become the standard of care. Here, we report our single institution 10‐year experience with CRS and HIPEC for appendiceal neoplasms. Methods This is a retrospective review from 1 January 2008 to 1 June 2017 of all patients undergoing CRS and HIPEC for appendiceal neoplasms. Institutional ethics approval was granted for this project. Results One hundred and seventy‐two patients underwent 208 CRSs during this time. Overall, 83.72% of patients had one CRS and HIPEC procedure. Pseudomyxoma peritonei from a perforated appendiceal mucinous neoplasm accounted for 67.9% of cases. The median peritoneal carcinomatosis index (PCI) was 14, with complete cytoreduction achieved in 74.2% of patients. Fifty‐four percent of patients had at least one complication, with one (0.5%) peri‐operative mortality in our cohort. For the entire cohort, the median overall survival was 104 months and a 5‐year survival of 75%. In those having a complete cytoreduction, 5‐year survival was 90%, with a median disease free interval of 63 months. PCI and completeness of cytoreduction were independent predictors of overall survival. Conclusion Our results demonstrate that CRS and HIPEC for appendiceal neoplasms are safe and effective. Despite carrying some morbidity, it offers patients an excellent disease free and overall survival.
