BackgroundThe modified Glasgow prognostic score (incorporating C-reactive protein and albumin) predicts survival in patients with gastro-intestinal tract cancer but has not been evaluated in patients with peritoneal malignancy. The aim was to evaluate the modified Glasgow score preoperatively in patients undergoing complete cytoreductive surgery (CCRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) for pseudomyxoma peritonei (PMP) of appendiceal origin.MethodsProspectively collected data from patients with PMP of appendiceal origin following CCRS and HIPEC between January 2007 and December 2011 were analysed. The mGPS was calculated from preoperative C-reactive protein and albumin. Predicted overall survival (OS) and disease-free survival (DFS) for each mGPS score were calculated using the Kaplan–Meier model. In a separate analysis, a comparison was made between mGPS and Tumour Markers (TM).Results260 patients were included in the study. The mGPS of 0, 1, and 2 were found in 111, 130, and 19 patients respectively. The median follow-up was 48 months. For mGPS-0, -1, and -2, the predicted OS was 82.2, 73.7, and 69.2 months and the DFS was 73.5, 62.9, and 54.4 months respectively. As mGPS increases, there is a reduction in long-term survival. There was no difference between mGPS and TM.ConclusionPreoperative mGPS may be a cost effective prognostic tool for predicting OS and DFS in patients following complete CRS-HIPEC, and performs well compared to TM for predicting patients at high risk of recurrence.
