Advanced Pseudomyxoma Peritonei Requiring Gastrectomy to Achieve Complete Cytoreduction Results in Good Long-Term Oncologic Outcomes

Optimal outcomes in pseudomyxoma peritonei (PMP) require complete macroscopic tumor removal by cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC). Partial or complete gastrectomy may be required with ongoing debate as to the risks and benefits of gastrectomy in what is often a low-grade malignancy.
