Prospective longitudinal study of quality of life following cytoreductive surgery and intraperitoneal chemotherapy for pseudomyxoma peritonei

BackgroundPseudomyxoma peritonei (PMP) is characterized by mucinous ascites, predominantly arising form a perforated tumour of the appendix. This study aimed to assess Health-Related Quality of Life (HRQL) in patients following cytoreductive surgery and intraperitoneal chemotherapy for PMP.MethodsOver a one year period, 49 consecutive patients (13 male, 36 females) with a median age of 55 (range 37–81 years) were enrolled. Patients were asked to complete the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 questionnaire prior to surgery and at one, three, six and twelve months post-operatively.Results26 patients (53%) underwent complete cytoreduction and 20 (42%) patients had major tumour debulking. One patient died from progressive disease three months from surgery and two patients withdrew from the study within 6 months of surgery. Baseline questionnaire compliance was 100 per cent and remained high (overall 98% of eligible patients) during follow up. Grade III/IV morbidity occurred in 4 patients (9%). Patients undergoing both complete cytoreduction and major tumour debulking reported a clinically significant improvement in emotional well-being, appetite and global HRQL at 1 year following surgery.ConclusionDespite the high morbidity associated with cytoreductive surgery and intraperitoneal chemotherapy, an improvement in quality of life at 1 year following the procedure was seen following both complete cytoreduction and major tumour debulking. Longer term assessment is required to demonstrate the durability of this enhancement.
