PURPOSE:
The study was designed to determine the maximum tolerated dose (MTD) of IP cisplatin [CDDP] combined with intravenous thiosulphate and concurrent whole abdomen hyperthermia for advanced, recurrent or progressive ovarian carcinoma..
METHODS and PATIENTS:
Between September 1991 and November 1998, 41 patients with advanced epithelial ovarian cancer received escalating doses of IP (IP) cisplatin (six cycles given every 3-4 weeks) and whole abdomen hyperthermia with intravenous thiosulphate as second line treatment. Whole abdomen hyperthermia was administrated using a BSD-2000 annular phased array system. Forty-one patients were enrolled in the phase I/II portions of the study. Forty-four per cent (18/41) had undergone sub-optimal cytoreductive surgery and 15% (6/41) had been optimally debulked of their disease. Ninety per cent (37/41) had platinum-resistant disease and 10% (4/41) had platinum-sensitive disease. No DLTs occurred in the phase I testing and the recommended dose for this combination schedule was 180 mg m-2 of IP cisplatin with thiosulphate and whole abdomen hyperthermia.
RESULTS:
The overall response rate was 44% (10 CR, 8 PR) and the median survival for all patients from protocol entry was 30 months (range 2-107 months). Median duration and survival of those achieving a pathologic CR was 14 months (range 2-27 months) and 35 months (range 14-71 months, 95% CI 16-54 months), respectively.
CONCLUSIONS:
Salvage platinum based IP cisplatin with hyperthermia did achieve pathologic CR in selected patients and was well tolerated. These promising results suggest a role for the use of adjuvant whole abdomen hyperthermia as a means of augmenting chemosensitization.
