[摘要] 目的 探讨体质量指数与乳腺癌相关临床病理特征的关系。 方法 本研究纳入2018年1月至2019年12月期间在苏州大学附属第一医院乳腺外科行手术治疗356例女性乳腺癌患者,将其按体质量指数(BMI)分为非超重组(BMI<24 kg/m2,n=196)和超重组(BMI≥24 kg/m2,n=160),分析BMI与其临床病理特征的关系。 结果 绝经后乳腺癌患者中,出现区域淋巴结转移的患者38.71%为非超重,61.29%为超重;增殖指标Ki-67<15%的绝经后患者中,59.68%为非超重,40.32%为超重;Ki-67>30%的绝经后患者中,35.71%为非超重,64.29%为超重,差异均有统计学意义(P<0.05)。 结论 体质量指数与绝经后乳腺癌临床病理特征密切相关。在绝经后乳腺癌患者中,与非超重者相比,超重者的淋巴结转移率较高,Ki-67表达较高。

[Abstract] Objective To explore the relationship between body mass index (BMI) and clinicopathological features related to breast cancer (BC). Methods A total of 356 female patients with BC who underwent breast surgery in the First Affiliated Hospital of Soochow University from January 2018 to December 2019 were included in this study. According to BMI, they were divided into the non-overweight group(BMI<24 kg/m2, n=196) and the overweight group (BMI ≥24 kg/m2, n=160). The relationship between BMI and clinicopathological features was analyzed. Results Among the postmenopausal BC patients, 38.71% patients with regional lymph node metastasis were non-overweight and 61.29% were overweight. Among the postmenopausal patients with Ki-67 <15%, 59.68% were non-overweight and 40.32% were overweight. Among postmenopausal patients with Ki-67 >30%, 35.71% were non-overweight and 64.29% were overweight, with statistically significant differences(P<0.05). Conclusion BMI is closely related to clinicopathological features of postmenopausal BC patients. Among postmenopausal BC patients, compared with non-overweight patients,overweight patients have a higher rate of lymph node metastasis and higher expression of Ki-67.

乳腺癌是女性發病率最高的恶性肿瘤之一。据统计,2019年美国新增女性乳腺癌患者27万,占女性恶性肿瘤的30%,死亡人数约占恶性肿瘤总体死亡人数的15%[1]。我国统计数据显示,2015年新发女性乳腺癌近27万人,死亡人数近7万[2]。因此,寻找和探索乳腺癌的发病危险因素及相关机制,以期探寻相关干预治疗措施,具有重要意义。近年来,已有大量研究证实肥胖与恶性肿瘤的发生发展有着非常密切的联系,但是关于肥胖和乳腺癌这一特定肿瘤之间的关系,目前仍存在争议。本研究旨在探讨体质量指数(Body mass index,BMI)与乳腺癌相关临床病理特征之间的关系,现报道如下。

1 资料与方法

1.1 一般资料

本研究初筛了2018年1月至2019年12月期间在我院乳腺外科行手术治疗的乳腺癌患者422例,均为初诊的女性患者,且术前未行新辅助治疗,诊断依据为世界卫生组织2012年[3]及2020年更新版[4]病理诊断标准,确诊为乳腺癌的患者。排除既往有肿瘤病史,入院前曾行任何抗肿瘤治疗及病历资料缺失较多的患者。最终356例女性乳腺癌患者纳入本次回顾性研究。……
