AIM: The present study reports our experience concerning with the advanced cancer treatment (cytoreductive surgery and hyperthermic intraperitoneal chemotherapy) in patients with advanced ovarian cancer ephitelial (AEOS) or recurrent ovarian cancer ephitelial (REOC).
METHODS: In a period from October 2006 to December 2009, we observed 25 patients affected by advanced ephitelial ovarian cancer or recurrent ephitelial ovarian cancer. All patients underwent CRS + HIPEC procedures. Peritoneal involvement was valued according to the Peritoneal Cancer Index (PCI) and the remaining postoperative disease according to the Completeness of Cytoreduction score (CC). HIPEC was always performed with closed technique for 60 min, with an average inflow temperature of 42.5 °C. The drugs were administered in combination according two schemes: 1) cisplatin 60 mg/m2/L and caelyx 20 mg/m2/L; 2) 60 mg/m2/L taxotere and caelyx 20 mg/m2/L. Morbidity and mortality were evaluated in accordance with the NCI CTCAE v. 3.0 (USA). Finally, the Disease Free Survival and Overall Survival by the Kaplan-Meier method was rated.
RESULTS: The average age observed was 64 years (range 46-76). Fourteen patients (56%) were affected by AEOC. From this group, 12 (48%) were subjected to neoadjuvant therapy and 2 (8%) to surgery as a first; 11 (44%) patients had REOC and all of them had previously undergone to surgery and adjuvant CHT. The average PCI was 12.63 (range 2-27). In 22 patients (88%), cytoreduction was considered total or almost total (CC-0 in 14 patients, CC-1 in 8); in 3 patients (12%), it had not been optimal (CC-2 or CC-3). In all 18 patients with PCI less than 15, it was possible to achieve an optimal cytoreduction, and this was possible only in 3 of the 7 patients who had a PCI greater than 15. The average operative time, including HIPEC, was of 612 min (range 425 min-840 min). In 9 patients (36%), the postoperative course was uncomplicated, in 10 patients (40%) complications were minor (G1-G2) and in 4 patients (16%) morbidity was important (G4). Mortality rate was 8%. The average OS was 30.8 months and the median OS was 30.8 months (respectively 36.5 months for AEOC and 27 months for REOC). The median DFS total (calculated from the day of surgery or from the day of the beginning of the CHT) was 12months (respectively 12.9 months for AEOC, 11.9 months for REOC).
CONCLUSION: Although the CRS and HIPEC procedure in the treatment of advanced or recurrent ovarian cancer represents now a reliable method with good results both in terms of morbidity and of distance results, there are still many controversial aspects that may in the future be better clarified only with a randomized phase III study, which is in progress, involving international working groups and experts on the procedure.
