Most premenopausal patients with early breast cancer (eBC) are diagnosed with hormone receptor-positive disease and therefore candidate for adjuvant endocrine therapy (ET).
The Gruppo Italiano Mammella (GIM) 23-POSTER (GIM23) is a multicenter, prospective, observational study conducted in 26 Italian institutions, aiming to evaluate ET choices for premenopausal patients affected by hormone receptor-positive eBC in a real-world setting. Here we report also the results in terms of type of ET prescribed according to the definition of high-risk patients by monarchE and NATALEE trials.
Between October 2019 and June 2022, 600 premenopausal patients were included, with a median age of 46 years. Almost half (271, 45.2 %) of the patients had stage I disease, while 254 (42.3 %) and 60 (10.0 %) patients had stage II and III, respectively. Overall, 149 (25.1 %) patients received tamoxifen alone, 83 (14.0 %) tamoxifen with ovarian function suppression (OFS), while 361 (60.9 %) received aromatase inhibitor (AI) with OFS. Patients treated with AI and OFS had higher number of metastatic axillary nodes, higher grade and more often received chemotherapy (all p < 0.001). According to the inclusion criteria of the monarchE and NATALEE trials, 81 patients (15.6 %) were considered high-risk for the monarchE and received AI with OFS in 88.9 % of the cases, while 231 patients (44.4 %) were considered high-risk for the NATALEE trial and received AI with OFS in 74.5 % of cases.
AI with OFS is the most prescribed adjuvant ET among premenopausal patients, especially in the presence of high-risk features.
大多数绝经前早期乳腺癌(eBC)患者被诊断为激素受体阳性疾病,因此是辅助内分泌治疗(ET)的候选者。
意大利乳腺小组(GIM)23-POSTER(GIM23)是一项在 26 家意大利机构进行的多中心、前瞻性、观察性研究,旨在评估绝经前激素受体阳性 eBC 患者在真实环境中接受 ET 的选择。在这里,我们还根据 monarchE 和 NATALEE 试验中高危患者的定义报告了根据 ET 类型规定的结果。
2019 年 10 月至 2022 年 6 月期间,共纳入 600 例绝经前患者,中位年龄为 46 岁。近一半(271 例,45.2%)患者为 I 期疾病,254 例(42.3%)和 60 例(10.0%)患者分别为 II 期和 III 期。总体而言,149 例(25.1%)患者接受单独他莫昔芬治疗,83 例(14.0%)患者接受他莫昔芬联合卵巢功能抑制(OFS)治疗,而 361 例(60.9%)患者接受芳香化酶抑制剂(AI)联合 OFS 治疗。接受 AI 和 OFS 治疗的患者腋窝淋巴结转移数量更多、肿瘤分级更高且更常接受化疗(均 p<0.001)。根据 monarchE 和 NATALEE 试验的纳入标准,81 例(15.6%)患者被认为是 monarchE 的高危患者,其中 88.9%的患者接受 AI 联合 OFS 治疗,而 231 例(44.4%)患者被认为是 NATALEE 试验的高危患者,其中 74.5%的患者接受 AI 联合 OFS 治疗。
绝经前患者中最常使用 AI 联合 OFS 作为辅助 ET,尤其是存在高危特征时。
