Concurrent interstitial radiotherapy and infusional chemotherapy for recurrent gynecologic malignancies.
Patients with unresectable locally recurrent gynecologic malignancies pose a difficult therapeutic challenge. Conventional therapies are frequently unsuccessful and offer only marginal palliation. In this study, interstitial 192iridium-needle implants and concomitant infusional 5-fluorouracil (5FU) and cisplatin (CDDP) or carboplatin (CBDCA) chemotherapy were used to treat 14 women with recurrent pelvic tumors. Malignancies of the cervix, endometrium ovary, tube and vulva are represented; all patients were heavily pretreated. Twenty interstitial implants were performed in these 14 patients. Needle distributions and doses were individualized to accommodate the recurrent tumor volumes. Tumor responses were seen in 12 patients (six complete and six partial responses). Four women remain clinically free of disease and four are alive with disease at 18-34 months of follow-up. There were no severe acute toxicities, however, four patients have subsequently developed fistulae associated with tumor progression. Although longer follow-up is required, the high response rate, wide applicability and acceptable toxicity observed in this heavily pretreated patient population warrant further study of combined interstitial radiation and chemotherapy.
