RESUMO
Objective:To evaluate the clinical prognosis of patients with pseudomyxoma peritonei (PMP) after cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC).Methods:The clinical data of 42 patients with PMP after CRS combined with HIPEC in the Affiliated Haikou Hospital of Xiangya Medical College of Central South University from January 2012 to December 2018 was retrospectively analyzed. All patients underwent open surgery CRS combined with HIPEC, the operation condition and prognosis of patients were analyzed.Results:In 42 patients with PMP, the disenminated peritoneal adenomucinosis (DPAM) accounted for 61.9% (26/42), the peritoneal mucinous carcinomatosis (PMCA) accounted for 28.6% (12/42), and the borderline accounted for 9.5% (4/42). The incidence rate of major operative complications (grade Ⅲ-Ⅳ) after CRS combined with HIPEC was 21.4% (9/42). The logistic regression analysis showed that the previous surgery score ( OR = 35.765, 95% CI 2.746-43.986, P = 0.001) and completeness of CRS score ( OR = 23.865, 95% CI 1.345-347.876, P = 0.028) were independent factors influencing major postoperative complications in PMP patients. The overall survival time of 42 patients with PMP was (64.8±4.1) months, and the disease-free survival time was (54.0±4.9) months; the 3-year and 5-year overall survival rates were 80.8% and 65.9%, and the 3-year and 5-year disease-free survival rates were 59.5% and 54.6%, respectively. The difference in overall survival time of patients with different pathological subtypes was statistically significant ( P = 0.022). Conclusion:CRS combined with HIPEC is safe and effective for treatment of patients with PMP, and most of the patients have a good prognosis.
