Background:
Higher Peritoneal Cancer Index (PCI) requires more extensive surgery and maybe associated with more limited outcomes. The aim of this study in a high-volume centre in Australia was to analyse the outcomes in PCI 39 patients regarding short and long term outcomes in appendiceal tumours.
Methods:
A retrospective analysis of prospectively maintained database of patients that underwent primary cytoreductive surgery (CRS) + hyperthermic intraperitoneal chemotherapy (HIPEC) with PCI 39 at St George Hospital, Sydney from 1996 to 2018. Patients with appendiceal tumours (inclusive of high and low grade) were analysed. Factors contributing to high grade (III/IV Clavien-Dindo) morbidity and mortality were assessed.
Results:
Of the 1201 patients in the database, 58 patients had a PCI 39 from appendix tumours at their first operation. The overall survival rate at 1, 3 and 5 year was 91.2%, 79.5% and 62.9% respectively. The median survival was 87.2 months (96% CI 51.8-NR). The rate of major morbidity was 71%. The postoperative mortality incidence was 1.7%. The median hospital length of stay was 34 days (IQR:27-54 days).
Conclusions:
In an experienced centre CRS + HIPEC is safe in selected patients with PCI 39. Despite the high morbidity, the overall survival for appendiceal tumours appear considerably better than debulking surgery.
