来曲唑与氨鲁米特对照治疗绝经后晚期乳腺癌113例

目的对比来曲唑和氨鲁米特治疗妇女绝经后晚期乳腺癌患者的有效性和耐受性。方法采用开放、随机、多中心对照研究。患者随机分组接受口服来曲唑2.5mg.d~(-1)或氨鲁米特1g.d(-1)的对照治疗。结果来曲唑组(n=59)有效率23.73%(CR 2例,PR 12例,ITT 有效率21.88%),SD 20.31%(13例)。氨鲁米特组(n=54)有效率11.11%(CR 1例,PR 5例,ITT 有效率10.17%),SD 20.34%(12例),2组疗效无统计学差异(P>0.05)。来曲唑组和氨鲁米特组不良反应发生率分别为18.64%和42.11%,与治疗相关的不良反应发生率分别为13.56%和33.33%。比较2组总的和与治疗相关的不良反应发生率均以来曲唑组明显较低,P 值均为0.002。结论来曲唑对绝经后、ER/PR 阳性或不明的晚期乳腺癌患者有效率为23.73%,与氨鲁米特比较无统计学差异。但来曲唑不良反应较氨鲁米特明显低,可以代替氨鲁米特用于晚期绝经后受体阳性或不明乳癌患者的治疗。     

A trial-based cost-effectiveness analysis of letrozole followed by tamoxifen versus tamoxifen followed by letrozole for postmenopausal advanced breast cancer.

BACKGROUND: Third-generation aromatase inhibitors are being considered as an alternative to tamoxifen as first-line therapy for advanced breast cancer. These newer therapies are more expensive, and will gain greater acceptance if they can demonstrate cost-effectiveness. METHODS: Life table analyses are used to compare the costs and benefits [life years gained and quality-adjusted life years (QALYs) gained] of treating postmenopausal women with advanced breast cancer with first-line letrozole (with the option of second-line tamoxifen) compared with first-line tamoxifen (with the option of second-line letrozole). Patient-level data from a large clinical trial describes the effectiveness of the therapy options, clinicians estimate resource usage and utility values are obtained from the literature. RESULTS: The mean cost of providing first- and second-line hormonal therapy is pound 4765 if letrozole is the first-line therapy and pound 3418 if tamoxifen is provided first (a difference of pound 1347). However, patients receiving letrozole as first-line therapy gain an additional 0.228 life years, or 0.158 QALYs. The cost-effectiveness analysis found that first-line hormonal therapy with letrozole gains additional life years at a cost of pound 5917, whilst the cost per additional QALY gained is pound 8514. CONCLUSION: The strategy of letrozole as first-line hormonal therapy not only provides an opportunity for extending and improving patient's quality of life, but also is highly cost-effective compared with other generally accepted medical treatments.

Locally advanced/inflammatory breast cancers treated with intensive epirubicin-based neoadjuvant chemotherapy: are there molecular markers in the primary tumour that predict for 5-year clinical outcome?

BACKGROUND: Locally advanced and/or inflammatory breast cancer (LABC) is a heterogeneous disease. Molecular markers may help to understand this heterogeneity. This paper reports the results of a study assessing the potential prognostic or predictive value of HER-2, p53, cyclinD1, MIB1, ER and PgR expression by immunohistochemistry from patients included in an EORTC-NCIC-SAKK trial. PATIENTS AND METHODS: A total of 448 patients with a cytological or histological diagnosis of LABC were randomised into a trial comparing two anthracycline-based neoadjuvant regimens. Chemotherapy was followed by standard locoregional therapy. Survival was comparable in both arms. We collected and analysed centrally paraffin-embedded tumour specimens from 187 (72.5%) of 258 patients that had a histological diagnosis. RESULTS: Of the patients included in this molecular marker study 114 relapsed and 91 died. In the multivariate analysis p53 positivity was associated with a shorter progression-free survival [hazard ratio (HR) = 1.96; 95% CI 1.33-2.91; P = 0.0008) and a shorter overall survival (HR = 1.98; 95% CI 1.28-3.06; P = 0.002). PgR positivity predicted for a longer overall survival (HR = 0.54; 95% CI 0.35-0.83; P = 0.0045). CONCLUSIONS: p53 was an independent factor predicting for survival. In order to clarify whether p53 is a pure prognostic and/or a predictive factor, a phase III trial is being conducted (EORTC 10994/BIG 00-01 study) using functional assay in yeast from frozen tumour samples.
