摘要:

目的 探讨雌激素受体阳性乳腺癌患者孕激素受体(PR)对体质量指数与预后关系的影响。 方法 收集 2012 3 月至 2018 1 月山西白求恩医院住院的病理证实为浸润性导管癌患者 1 036 例。以 体质量指数(BMI)24 kg/m2 为分界值,将患者分为 BMI ≥ 24 kg/m2组(608 例)和 BMI<24 kg/m2组(428 例)。 采用免疫组织化学法检测肿瘤 PR 状态。比较 BMI 不同水平组间临床病理特征的差异;采用 Kaplan⁃Meier 法绘制全组和 PR 分层患者中 BMI 不同水平两组的总生存(OS)曲线,并行 log⁃rank 检验。采用单因素和 多因素 Cox 比例风险模型分析影响 OS 的因素。结果 中位随访 4.0 年(2.3 ~ 5.7 年)。BMI < 24 kg/m2 BMI ≥ 24 kg/m2 组间年龄、组织学分级、分期、月经状态、肿瘤家族史不同,差异有统计学意义(均 P 0.05)。全组中,BMI < 24 kg/m2 OS 优于 BMI ≥ 24 kg/m2组(P = 0.033);在 PR 阴性的 ER 阳性乳腺癌患 者中,BMI < 24 kg/m2 OS 优于 BMI ≥ 24 组(P = 0.007);PR 阳性的 ER 阳性乳腺癌患者中,BMI < 24 kg/m2 组和 BMI ≥ 24 kg/m2 组间 OS 差异无统计学意义(P = 0.466)。单因素 Cox 回归分析显示,BMI、PR、分期、 月经状态与 ER 阳性乳腺癌患者 OS 相关(均 P<0.05);多因素 Cox 回归分析显示,BMI ≥ 24 kg/m2(HR = 1.916,95% CI:1.167 ~ 3.144,P = 0.010)、PR 阴性(HR = 0.348,95% CI:0.208 ~ 0.583,P<0.001)为 ER 性乳腺癌患者 OS 的独立危险因素。结论 PR 阳性、ER 阳性肥胖乳腺癌患者相比,PR 阴性、ER 性患者生存率更低,因此,PR 状态与 ER 阳性肥胖乳腺癌患者预后相关,为乳腺癌预防和诊治提供理 论依据。

Abstract:


Objective This study aims to explore whether the association between body mass index(BMI and prognosis of estrogen receptor positive(ER+)breast cancer(BC)varies according to the tumor PR status. Methods We collected a total of 1 036 cases with invasive ductal breast cancer from March 2012 to January 2018 in department of breast surgery of Shanxi Bethune Hospital. Women were stratified according to their BMI(< 24 ≥ 24 kg/m2). Tumor PR status(PR-,PR+)was evaluated by immunohistochemistry. The differences of clinico⁃ pathological features between the groups with different BMI levels were compared;Kaplan⁃Meier method was used to draw the overall survival(OS)curve of the whole group and the patients stratified by PR with different BMI levels,and log⁃rank test was performed. Univariate and multivariate Cox proportional hazards models were used to analyze the factors affecting OS. Results The median follow ⁃ up period was 4.0 years(2.3 ~ 5.7 years). There were significant differences in age,histological grade,stage,menstrual status and family history of tumor between BMI < 24 kg/m2 group and BMI ≥ 24 kg/m2 group(P < 0.05). In the whole group,OS in BMI <24 kg/m2 group was better than that in BMI ≥ 24 kg/m2 group(P = 0.033). In breast cancer patients with PR ⁃ and ER+,OS in BMI < 24 kg/m2 group was better than that in BMI ≥ 24 kg/m2(P = 0.007);In breast cancer patients with PR+ and ER+,there was no significant difference in OS between BMI < 24 kg/m2 group and BMI ≥ 24 kg/m2 group(P 0.466). Univariate Cox regression analysis showed that BMI,PR,stage and menstrual status were associated with OS in ER positive breast cancer patients(P < 0.05). Multivariate Cox regression analysis showed that BMI ≥ 24 kg/m2 (HR = 1.916,95% CI:1.167 ~ 3.144,P = 0.010)and PR negative(HR = 0.348,95% CI:0.208 ~ 0.583,P < 0.001 were independent risk factors for OS in ER positive breast cancer patients. Conclusion Compared with PR+,ER+ obese breast cancer patients,PR-,ER+ women had poorer survival. It suggests that poorer survival is associated with high BMI among women diagnosed with ER+ BC,which provides reference for the prevention and treatment of breast cancer.
