commentary/Japanese study - Carbo/Taxol - Dose-Dense Chemotherapy for Ovarian Cancer - National Cancer Institute



"...Women with advanced ovarian cancer lived longer and without their tumors growing after receiving a modified regimen of a standard chemotherapy drug combination, Japanese researchers have reported. In a large phase III clinical trial, the researchers randomly assigned women to receive six cycles of carboplatin and paclitaxel (Taxol) every 3 weeks (standard regimen) or six cycles of carboplatin every 3 weeks and a lower dose of paclitaxel (Taxol) once a week (dose-dense regimen). Women in the dose-dense group had a 29 percent reduction in the risk of progression and a 25 percent reduction in the risk of death after 3 years of follow-up. The results were published online September 18, 2009, in The Lancet (see the journal abstract).
Although the dose-dense regimen had more toxic effects than the standard regimen, survival benefits of this magnitude "have been rare in women with advanced ovarian cancer," wrote. Noriyuki Katsumata, M.D., and colleagues from the Japanese Gynecologic Oncology Group (JGOG).
The results, explained Ted Trimble, M.D., M.P.H., from NCI's Division of Cancer Treatment and Diagnosis, are consistent with what has been seen in breast cancer using a dose-dense chemotherapy regimen. The idea, he continued, is "to balance efficacy and toxicity by using a weekly schedule rather than every 3 weeks."...."
