Abstract
BACKGROUND: Cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are an established treatment for pseudomyxoma peritonei (PMP), but it is a major surgical procedure and may be associated with long-term morbidity. To date, health-related quality-of-life (HRQL) data among survivors are lacking. METHODS: A two-period qualitative study investigated patients undergoing CRS-HIPEC for PMP at a national peritoneal tumor center between 2003 and 2011. First, the European Organization for Research and Treatment (EORTC)-QLQ C30 HRQL questionnaire was used longitudinally preoperatively and at postoperative months 3, 6, 9, 12, 18, and 24, then yearly thereafter. Second, it was updated in 2016 as a cross-sectional study. Both studies were compared with age- and sex-matched reference populations (one-way t tests). RESULTS: A total of 553 longitudinal HRQL questionnaires were completed for 137 patients, truncated at 60 months. In the 2016 update, 85 responses were received from 103 survivors (mean follow-up period, 8.11 years). Patients' physical, role, and social function scores were impaired until 12 months postoperatively, after which the scores did not differ significantly from those of with reference populations. Similarly, fatigue, appetite loss, insomnia, and financial difficulties worsened significantly compared with reference populations in the first 12-months and then normalized. In contrast, impaired cognitive function (82.3 vs 88.5; P = 0.017), constipation (13.7 vs 7.3; P = 0.032), and diarrheal symptoms (15.1 vs 4.9; P = 0.0006) persisted through both periods. Global health scores did not differ significantly from those of the reference population. CONCLUSIONS: Beyond 12 months postoperatively, CRS-HIPEC for PMP is associated with a good quality of life except for some cognitive functional impairment and bowel disturbances.
