目的
2
探讨乳腺癌新辅助化疗(NACT)后肿瘤退缩模式的影响因素,构建肿瘤退缩模式的预测模型并进行验证。
方法
2
选取2019年3月1日至2024年3月1日期间接受NACT的1 314例乳腺癌患者作为研究对象,随机分为验证队列(
n
=301)和研究队列(
n
=603)。研究队列中,根据NACT后肿瘤退缩模式将患者进一步分为向心性退缩组(病例组,
n
=387)与非向心性退缩组(对照组,
n
=216)。收集两组患者的一般临床病理资料并进行比较,采用非条件Logistic回归分析NACT后肿瘤退缩模式的影响因素并建立预测模型,使用Hosmer-Lemeshow检验和受试者工作特征(ROC)曲线评价模型的拟合优度与预测性能,并进行外部验证。
结果
2
研究队列中,174例(28.9%)患者达到病理学完全缓解(pCR),213例(35.3%)呈单灶退缩,92例(15.3%)呈多灶退缩,78例(12.9%)呈主残余病灶伴卫星病灶,43例(7.1%)为疾病稳定,3例(0.5%)出现疾病进展。两组间年龄、雌激素受体(ER)、孕激素受体(PR)、Ki-67、人表皮生长因子受体2(HER2)、组织学分级、预后营养指数(PNI)及化疗方案的差异均有统计学意义(均
P
< 0.05)。Logistic回归分析显示,年龄(OR=0.563,95% CI:0.358~0.885)、ER(OR=0.521,95% CI:0.350~0.773)、PR(OR=0.552,95% CI:0.379~0.806)、HER2(OR=3.729,95% CI:2.488~5.590)、Ki-67(OR=1.804,95% CI:1.071~3.039)、PNI(OR=2.285,95% CI:1.307~3.997)和组织学分级(Ⅲ级)(OR=2.194,95% CI:1.283~3.751)是NACT后向心性退缩的独立影响因素(均
P
< 0.05)。该logistic回归模型的Hosmer-Lemeshow检验
P
值为0.927,ROC曲线下面积为0.731(95% CI:0.690~0.772,
P
< 0.001)。外部验证结果显示,该预测模型的ROC曲线下面积为0.764(95% CI:0.709~0.820,
P
< 0.001),敏感度为75.0%,特异度为65.7%,约登指数为0.407。
结论
2
该Logistic回归模型具有较高的预测价值,可为临床医生预测乳腺癌患者NACT后的肿瘤退缩模式提供参考。
Objective
2
To explore the influencing factors of tumor regression patterns after neoadjuvant chemotherapy (NACT) in breast cancer, construct and validate a predictive model for tumor regression patterns.
Methods
2
A total of 1 314 breast cancer patients who received NACT between March 1, 2019, and March 1, 2024, were selected as study subjects and randomly divided into a validation cohort (
n
=301) and a study cohort (
n
=603). Within the study cohort, patients were further stratified based on post-NACT tumor regression pattern
s into a concentric regression group(case group)(
n
=387) and a non-concentric regression group(control group)(
n
=216). General clinicopathological data were collected and compared between the two groups. Unconditional logistic regression was used to analyze the influencing factors of tumor regression patterns post-NACT and establish a predictive model. The Hosmer-Lemeshow test and receiver operating characteristic (ROC) curve were employed to evaluate the model's goodness-of-fit and predictive performance, followed by external validation.
Results
2
Among all subjects in the study cohort, 174 patients (28.9%) achieved pathological complete response (pCR), 213 (35.3%) showed unifocal regression, 92 (15.3%) had multifocal regression, 78 (12.9%) presented main residual lesions with satellite lesions, 43 (7.1%) had stable disease, and 3 (0.5%) experienced disease progression. Significant differences were observed between the two groups in age, estrogen receptor(ER), progesterone receptor(PR), Ki-67, human epidermal growth factor receptor 2(HER2), histological grade, prognostic nutritional index(PNI), and chemotherapy regimen (all
P
< 0.05). Logistic regression analysis revealed that age (OR=0.563, 95% CI: 0.358–0.885), ER (OR=0.521, 95% CI: 0.350–0.773), PR(OR=0.552, 95% CI: 0.379–0.806), HER2(OR=3.729, 95% CI: 2.488–5.590), Ki-67 (OR=1.804, 95% CI: 1.071–3.039), PNI (OR=2.285, 95% CI: 1.307–3.997) and histological grade (Ⅲ) (OR=2.194 95% CI: 1.283–3.751) were independent influencing factors for concentric regression post-NACT (all
P
< 0.05). The Hosmer-Lemeshow test for the logistic regression model yielded a
P
-value of 0.927, and the area under the ROC curve was 0.731 (95%CI: 0.690-0.772,
P
< 0.001). External validation demonstrated that the area under the ROC curve of this prediction model was 0.764 (95% CI: 0.709–0.820,
P
<0.001), with a sensitivity of 75.0% and a specifi
city of 65.7%. The Youden's index was 0.407.
Conclusion
2
This logistic regression model exhibits high predictive value and provides a reference for clinicians to predict tumor regression patterns in breast cancer patients after NACT.
