Abstract:

Objective

To identify the predictive factors for pathological complete response (pCR)in elderly patients with breast cancer undergoing neoadjuvant therapy (NAT).

Methods

A retrospective analysis was conducted on elderly patients with breast cancer (≥65 years) who received NAT at the Department of Breast of Sichuan Cancer Hospital from October 2014 to December 2023. The correlation between clinicopathological characteristics and pCR was analyzed. Univariate analysis was performed using the chi-square test or Fisher’s exact test, while multivariate analysis was conducted by binary logistic regression.

Results

A total of 132 older patients were included in this study, of whom 22 achieved a pCR,with an overall pCR rate of 16.7%. Univariate analysis showed statistically significant associations of higher pCR rates with hormone receptor (HR) negativity (P=0.004), human epidermal growth factor receptor 2(HER2) positivity (P<0.001), and high Ki67 expression (P=0.013). Multivariate analysis revealed that HR negativity (odds ratio [OR]=3.244; 95% confidence interval [CI]: 1.010~10.421; P=0.048) and HER2 positivity (OR=17.907; 95%CI: 5.180~61.908; P<0.001) were independent predictive factors for pCR in elderly patients with breast cancer undergoing NAT. Subgroup analysis suggested a significant correlation of pCR rate with molecular subtypes based on HR and HER2 status (P<0.001). In HER2-positive breast cancer,the pCR rate was significantly higher in patients who received anti-HER2 therapy than in those who did not(60.0% vs 23.1%, P=0.031).

Conclusion

HR negativity and HER2 positivity are independent predictive factors for pCR in elderly patients with breast cancer receiving neoadjuvant therapy.
