Background:
Pseudomyxoma peritonei is a disease caused by the widespread distribution of mucinous tumor into the peritoneal space from a perforated appendiceal neoplasm.
Methods:
All patients in this study had cytoreductive surgery with total gastrectomy plus perioperative intraperitoneal chemotherapy. A high diverting jejunostomy was used on all patients. Patient characteristics, adverse events, and survival were accumulated prospectively.
Results:
Fifty-eight patients were available for long-term follow-up. In the univariate analysis, features associated with a less favorable outcome included female gender (p = 0.0127), intestinal obstruction before treatment (p = 0.00791), and prior surgical score (PSS) (p = 0.0054). In the multivariate analysis, the two significant variables were grade (p = 0.0458) and PSS (p = 0.0041). Median survival was 12 years with a 5-, 10-, and 20-year survival of 76%, 58%, and 37%, respectively. There were two postoperative deaths (3.4%) and Grades 3 and 4 adverse events in 20 (34.5%) patients.
Conclusions:
A 10-year survival after cytoreductive surgery, total gastrectomy with temporary high diverting jejunostomy, and perioperative chemotherapy occurred in 58% of these patients with advanced pseudomyxoma peritonei. High-grade disease and extensive prior surgery with a high PSS were associated with reduced benefit.
