Summary Background We compared standard adjuvant anthracycline chemotherapy with anthracycline–taxane combination chemotherapy in women with operable node-positive breast cancer. Here we report the ...final, 10-year follow-up analysis of disease-free survival, overall survival, and long-term safety. Methods BCIRG 001 was an open label, phase 3, multicentre trial in which 1491 patients aged 18–70 years with node-positive, early breast cancer and a Karnofsky score of 80% or more were randomly assigned to adjuvant treatment with docetaxel, doxorubicin, and cyclophosphamide (TAC) or fluorouracil, doxorubicin, and cyclophosphamide (FAC) every 3 weeks for six cycles. Randomisation was stratified according to institution and number of involved axillary lymph nodes per patient (one to three vs four or more). Disease-free survival was the primary endpoint and was defined as the interval between randomisation and breast cancer relapse, second primary cancer, or death, whichever occurred first. Efficacy analyses were based on the intention-to-treat principle. BCIRG 001 is registered with ClinicalTrials.gov , number NCT00688740. Findings Enrolement took place between June 11, 1997 and June 3, 1999; 745 patients were assigned to receive TAC and 746 patients were assigned to receive FAC. After a median follow-up of 124 months (IQR 90–126), disease-free survival was 62% (95% CI 58–65) for patients in the TAC group and 55% (51–59) for patients in the FAC group (hazard ratio HR 0·80, 95% CI 0·68–0·93; log-rank p=0·0043). 10-year overall survival was 76% (95% CI 72–79) for patients in the TAC group and 69% (65–72) for patients in the FAC group (HR 0·74, 0·61–0·90; log-rank p=0·0020). TAC improved disease-free survival relative to FAC irrespective of nodal, hormone receptor, and HER2 status, although not all differences were significant in these subgroup analyses. Grade 3–4 heart failure occurred in 26 (3%) patients in the TAC group and 17 (2%) patients in the FAC group, and caused death in two patients in the TAC group and four patients in the FAC group. A substantial decrease in left ventricular ejection fraction (defined as a relative decrease from baseline of 20% or more) was seen in 58 (17%) patients who received TAC and 41 (15%) patients who received FAC. Six patients who received TAC developed leukaemia or myelodysplasia, as did three patients who received FAC. Interpretation Our results provide evidence that the initial therapeutic outcomes seen at the 5-year follow-up with a docetaxel-containing adjuvant regimen are maintained at 10 years. However, a substantial percentage of patients had a decrease in left ventricular ejection fraction, probably caused by anthracycline therapy, which warrants further investigation. Funding Sanofi.
Background Despite improvements in diagnosis and treatment, the prevalence of hyperlipidemia among adults in the United States remains high. Data are limited on treatment patterns and patient ...perceptions of cardiovascular disease risk since the release of new lipid guidelines. Objectives The objectives of the PALM registry are to assess contemporary patterns of lipid-lowering therapy use among adults receiving care in a nationally representative cohort of community clinics, determine consistency of treatment with varying lipid guidelines, identify factors affecting use of lipid-lowering therapy including patient-reported statin intolerance, and assess patient and provider knowledge of cardiovascular risk reduction goals. Study Design The PALM registry will enroll 7,500 patients likely to be considered for lipid-lowering therapy from 175 cardiology, primary care, and endocrinology practices across the United States. In this cross-sectional, observational registry, a novel tablet-based platform will be used to collect patient-reported knowledge, attitudes, and beliefs regarding cardiovascular risk reduction and lipid management. Chart abstraction and core laboratory lipid levels will describe current lipid management. Provider surveys will assess perception of current lipid-lowering goals and barriers to optimal cardiovascular risk reduction. Conclusion The PALM registry will allow for better understanding of current practice patterns, patient experiences, and patient and provider attitudes toward cholesterol management for cardiovascular disease risk reduction. These data can be used to better understand gaps in care and design targeted interventions to improve uptake of lipid-lowering therapies for cardiovascular risk reduction.
