Treatment patterns for adjuvant docetaxel-based chemotherapy in early-stage breast cancer in China: A pooled retrospective analysis of four observational studies

摘要

Objective:Adjuvant docetaxel-based chemotherapy is frequently used for operable early breast cancer (EBC).This study investigated patterns of use of docetaxel (T) in real-life clinical practice in China.Methods:This was a retrospective pooled analysis of the Asia-Pacific Breast Initiatives (APBI) Ⅰ (2006-2008) and Ⅱ (2009-2011) registries,and two Chinese observational studies;BC STATE (2011-2014) and BC Local Registry (2007-2010).Female Chinese adults (≥18 years) with operable breast cancer treated with docetaxel-based adjuvant chemotherapy were included in the analysis.Patients with metastatic disease were excluded.The primary endpoint was assessment of treatment patterns and patient profiles.A logistic regression analysis was conducted to identify factors associated with choice of adjuvant chemotherapy regimen.Results:Data from 3,020 patients were included.The most frequently used adjuvant regimen was docetaxel/anthracycline combination [n=1,421 (47.1％);of whom 52.0％ received T/epirubicin (E)/cyclophosphamide (C)],followed by docetaxel/other [n=705 (23.3％);of whom 72.8％ received TC],docetaxel/anthracycline sequential [n--447 (14.8％);of whom 40.9％ and 39.6％ received 5-Fu/EC-T and EC-T,respectively],and "other" [n=447 (14.8％);of whom 91.5％ received T].A significant association was found between adjuvant therapy with docetaxel/anthracycline combination and patient weight,menopausal status and estrogen receptor status.Conclusions:Real-world data revealed that docetaxel/anthracycline combination is the most commonly used category of docetaxel-based adjuvant therapy for patients with operable breast cancer in China;of which TEC is the most frequently used regimen.
