Sequential multi-agent chemotherapy and whole abdominal irradiation for stage III ovarian carcinoma.
Modern therapy for stage III ovarian carcinoma patients usually involves one or more laparotomies with maximal resection of tumor, and intensive multi-agent chemotherapy. However, with long-term follow-up only 10-15% of patients remain free of disease. In the hope of improving outcome, we have treated 17 women with sequential multimodality therapy, including initial surgical resection (if possible), cyclophosphamide-adriamycin +/- cis-platinum, second-look surgery, and whole abdominal irradiation. Seven patients are currently alive without disease, with median follow-up of 52 months since initiation of radiation and 60 months since initiation of chemotherapy. Disease-free survival correlated with residual tumor at the start of radiotherapy: none (4/4); microscopic, less than or equal to 5 mm (3/4); greater than 5 mm or no surgery (0/9). Survival also correlated with tumor grade: grade 1 (2/2); grade 2 (2/3); grade 3 (3/11). Hematological tolerance of radiotherapy was dependent upon the number of chemotherapy cycles: ten of 11 patients receiving less than or equal to eight cycles completed radiotherapy without excessive delay, compared with only one of five receiving greater than eight cycles. There were no treatment-related deaths and only one patient required laparotomy for bowel obstruction. We conclude that intensive multimodal treatment may be tolerated moderately well if the amount of chemotherapy is limited, and that further studies are justified.
