The purpose of this study is to determine the effectiveness of the combination of the two drugs, docetaxel (Taxotere®) and carboplatin (Paraplatin®) followed by radiation directed at the tumor in treating your endometrial cancer.
Endometrial carcinoma is the most common malignancy in the female reproductive tract. For the percentage of patients with advanced stage (III - IV) optimum adjuvant therapy status-post surgical staging and/or optimal cytoreductive surgery is not well defined and limited in the rates of response. Survival rates range from 18 - 49% with high levels of toxicity with the current treatment regimens.(1)
The Gynecologic Oncology Group (GOG) explored the use of chemotherapy in protocol #107 comparing adriamycin with a combination of adriamycin and cisplatin.(2) This trial boasted a 45% response rate for the combination arm compared to a 27% response rate in the adriamycin only arm. Although no difference was seen in overall survival, the combination arm showed an improvement in progression free survival from 3.8 to 5.7 months. Subsequently, GOG protocol #122 randomized patients to this chemotherapeutic regimen versus whole abdominal radiation therapy. This trial is now closed to accrual and results are pending.
Ball et. al. reported on a phase II trial of paclitaxel in advanced or recurrent endometrial cancer done through the GOG.(3) At 250 mg/m2 (200mg/m2 for patients with previous radiation therapy) over 24 hours, every 21 days, 10/28 patients responded. There were 4 complete responders and 6 partial responders with an overall response rate of 35.7%. Toxicity was remarkably high with grade 3 and 4 neutropenia and neurotoxicity seen in 62% and 10.7%, respectively.
Dimpoulos et. al. reported the use of paclitaxel 175 mg/m2 over 3 hours and cisplatin 75mg/m2 every 21 days in advanced or recurrent endometrial carcinoma.(4) A 67% objective response rate was seen with 29% showing a complete response and 38% partial response. Toxicities included a 9%
grade 3 and 4 peripheral neuropathy rate. These response rates changed the standard of care in the community setting from the more toxic regimen of adriamycin and cisplatin to paclitaxel and carboplatin.
Hoskins et. al. substituted carboplatin for cisplatin in an effort to reduce the peripheral neuropathy seen in the Dimpoulos trial. This phase II combination of paclitaxel and carboplatin with radiation therapy in advanced endometrial cancer resulted in a 75% response rate. The median failure-free survival time was 23 months, with a 62% 3-year overall survival rate. Toxicities were primarily hematologic and reversible.(5)
The ongoing GOG protocol, #184, is exploring the combination of tumor directed radiation followed by a randomization to adriamycin and cisplatin versus adriamycin, cisplatin and paclitaxel with G-CSF support. Increased toxicity will be expected in the three-drug regimen. With a significant response rates to a combination of paclitaxel and carboplatin along with radiation therapy in the phase II setting it is hard to justify the added toxicity of this three-drug regimen.
The SCOTROC phase III trial comparing docetaxel (75 mg/m2) over 1 hour plus carboplatin (AUC 6) vs. paclitaxel (175 mg/m2) over 3 hours plus carboplatin (AUC 6) yielded equivalent overall response rates in 1,077 patients with ovarian cancer.(6) The docetaxel arm resulted in significantly less overall grade 2 and 3 sensory and motor neurotoxicity. Only 4 patients withdrew from the trial due to neurotoxicity on the docetaxel arm vs. 32 patients on the paclitaxel arm. However, the docetaxel arm resulted in a higher incidence of neutropenia and associated complications without compromising treatment delivery of overall safety.
Based on the information to date, it seems prudent to explore a phase II trial of docetaxel plus carboplatin every 3 weeks for 6 cycles followed by radiation therapy in the management of patients with advanced endometrial cancer. The proposed protocol design requires that chemotherapy be administered prior to radiation therapy in order to control distant metastatic disease before attempting to control for local-regional recurrences with radiation.
