Phase II study of carboplatin and whole body hyperthermia (WBH) in recurrent and metastatic cervical cancer.
OBJECTIVE
Hyperthermia enhances carboplatin cytotoxicity preclinically, and clinical studies have shown radiant heat Whole Body Hyperthermia (WBH) to be safe. In this study, the efficacy and toxicity of the combination of 41.8 degrees C WBH and carboplatin in recurrent and/or metastatic cervical cancer were explored.


METHODS
Recurrent and/or metastatic cervical cancer patients were treated with 41.8 degrees C WBH and concurrent carboplatin, cycled every 28 days (max. 6 cycles).


RESULTS
Twenty-one of 25 participants were evaluable for response: one complete remission, six partial responses, stable disease in nine patients and progression in five, leading to a response rate of 33%. Three of four evaluable chemotherapy pre-treated patients progressed, while this was seen in only 2 of 17 chemotherapy-naive patients. The median survival is 7.8 months (range 1.3 to 43+) and no patients were lost to follow up. Grades 3/4 toxicities were common: leukopenia in 35%, thrombopenia in 61% and anemia in 22% of all treatments. Excessive, partly reversible renal toxicity was seen in two patients (grades 3 and 4).


CONCLUSIONS
The efficacy of WBH and carboplatin in recurrent and/or metastatic cervical cancer seems comparable to that of other palliative chemotherapy regimens in this disease. The considerable toxicity, though largely manageable, includes unexpected and severe unacceptable renal toxicity. This regimen seems less suitable for palliative care.
