Abstract

Purpose: To evaluate the response rate of the combination of capecitabine (C) and vinorelbine (V) followed by Docetaxel (D) in the 1st line treatment of advanced and metastatic breast cancer patients.

Patients and methods: Patients with measurable disease and no prior chemotherapy in advanced disease were eligible. Pts received V 25 mg/m(2) on day 1 and 8 in combination with C 825 mg/m(2) twice a day from day 1 to 14 every 3 weeks for four cycles followed by 12 consecutive weeks of D 25 mg/m(2)/w.

Results: Between March 2002 and November 2003, 40 patients were enrolled. Median age was 57 years. Of patients, 77.5% of pts had visceral involvement and 32.5% had more than two metastatic sites. In the adjuvant setting, 62.5% received anthracycline and 10% Taxanes. In the intent-to-treat population, an overall objective response was observed in 25 patients (62.5, 95% CI, 45.8-77.27) and stable disease in 5 (12.5%). Median time till progression (TTP) was 12.3 months (range 1.5-48; 95% CI, 10.05-14.54). The median survival was 35.7 months (range 2-47). Reported grade 3-4 toxicities under Navcap were neutropenia (4 pts), anemia (1 pt), thrombopenia (1 pt) and febrile neutropenia (3 pts). Reported grade 3-4 toxicities under weekly Docetaxel were neutropenia (1 pt), thrombopenia (2 pts), leucopenia (1 pt) and anemia (1 pt).

Conclusion: The sequential use of Navcap followed by weekly Docetaxel demonstrated an interesting efficacy with a prolonged TTP and OS and warrants further evaluation.
