OBJECTIVE The Department of Defense health care system provides access to care without respect to age, race, or socioeconomic status. We sought to determine the effect of race as a predictor of survival in patients with endometrial cancer treated in the Department of Defense medical system. METHODS Information on patients with endometrial carcinoma was extracted from the Department of Defense centralized tumor registry for the period 1988 to 1995. Data included age at diagnosis, military status, race, tumor histology, grade, FIGO surgical stage, adjuvant therapies, and disease-free survival. The chi(2) test was used for analysis of prognostic factors and adjuvant treatments between racial groups. Actuarial survival curves were calculated by using the method of Kaplan and Meier and compared by the log-rank test. Variables found to be significant on univariate analysis (P < 0.05) were entered into a multivariate Cox regression analysis. RESULTS Of 1811 patients meeting criteria for the study, racial distribution was 90% Caucasian, 4.4% African-American, and 5.5% Asian-Pacific Islander. African-Americans had more advanced stages of disease compared to Caucasians (P < 0.001). Both African-Americans and Asian-Pacific Islanders had higher grade tumors and less favorable histologic types than Caucasians (P < 0.05). The extent of adjuvant therapies was similar for racial groups. African-Americans and Asian-Pacific Islanders had significantly worse 5-year disease-free survivals than Caucasians (P = 0.007). Additional poor prognostic factors included age >60 years, grade, unfavorable histology, and stage. On multivariate analysis age >60 years, stage, and Asian-Pacific Islander race remained significant prognostic factors. CONCLUSION African-Americans and Asian-Pacific Islanders had worse survivals than Caucasians. After controlling for imbalances in clinicopathologic factors, Asian-Pacific Islander race was found to be a newly identified poor prognostic factor.

In a randomized controlled trial (RCT) of patients with recurrent, platinum‐sensitive ovarian cancer, the combination weekly docetaxel and carboplatin was associated a with progression‐free survival (PFS) of 13.7 months compared with 8.4 months for sequential, single‐agent docetaxel followed by carboplatin. The objective of the current study was to construct a cost‐utility model to compare these 2 regimens with the incorporation of prospectively collected quality‐of‐life (QoL) data.

The aim of this randomized clinical trial was to evaluate the efficacy and safety of combination (cDC) and sequential (sDC) weekly docetaxel and carboplatin in women with recurrent platinum‐sensitive epithelial ovarian cancer (EOC).

OBJECTIVES A phase II clinical trial compared docetaxel in combination with carboplatin to sequential single agent docetaxel followed by carboplatin for treatment of recurrent platinum-sensitive ovarian, peritoneal, or tubal cancer. This manuscript reports prospectively collected health-related quality of life (HRQL). METHODS Participants were randomized to either weekly docetaxel 30 mg/m(2)/days 1 and 8 and carboplatin AUC 6/day 1 every 3 weeks (cDC) or docetaxel 30 mg/m(2)/days 1 and 8, repeated every 3 weeks for 6 cycles followed by carboplatin AUC 6/day 1 every 3 weeks for 6 cycles or until disease progression (sDC). The primary HRQL endpoint was the trial outcome index (TOI) score of the Functional Assessment of Cancer Therapy-Ovarian (FACT-O) instrument, and was assessed as an intent-to-treat analysis. The secondary HRQL endpoints included the FACT-O total score, the FACT-General, and several domain scores of the FACT-O instrument (physical well-being (PWB), social/family well-being (SWB), emotional well-being (EWB), functional well-being (FWB), and the ovarian cancer specific (OCS) module). The FACT-O was administered at randomization, prior to each of 6 cycles of treatment, and at study endpoint. RESULTS One hundred forty-eight participants were randomized to each group. Sequential docetaxel followed by carboplatin (sDC) was associated with significant improvements in the FACT-O TOI (p=0.013), FACT-O total score (p=0.033), and OCS (p=0.029) compared to the combination docetaxel and carboplatin group (cDC). CONCLUSIONS Sequential single agent docetaxel followed by carboplatin is associated with improved HRQL when compared to cDC. The improved progression-free survival observed with cDC should be weighed against lower quality of life during treatment.
