Objective:
To analyze the role of postmastectomy radiotherapy (PMRT) in moderate- and high-risk elderly breast cancer patients.
Methods:
The clinicopathological data of 874 breast cancer patients treated with mastectomy and axillary dissection were retrospectively analyzed. The T1-2N1 patients were defined as moderate- risk (IR) group, and T3-4 and/or N2-3 cases as high-risk (HR) group. The locoregional recurrence (LRR) and overall survival (OS) rates were calculated and compared according to different age groups and radiotherapy status. Kaplan-Meier method and Log-rank test was used for calculation and comparison of the survival curves of different patient groups.
Results:
The median follow up time was 47 months. 108 (12.4%) patients were > or = 65 years. For patients who were < 65 and > or = 65 years, 18.1% and 15.3% received PMRT in the IR group, and 82.7% and 52.2% received PMRT in the HR group, respectively. For patients > or = 65 years, the 5-year LRR rates were 0% and 14.2% (P = 0.242) and 5-year OS rates were 100% and 75.2% (P = 0.159) for the PMRT-IR and non-PMRT-IR groups, respectively. The 5-year LRR rates were 0% and 14.1% (P = 0.061), 5-year OS rates were 84.6% and 77.4% (P = 0.597) for the PMRT-HR and non-PMRT-HR groups, respectively. For patients < 65 years, the 5-year LRR rates were 0% and 9.9% (P = 0.035) and 5-year OS rates were 87.0% and 82.1% (P = 0.739) for the PMRT-IR and non-PMRT-groups, respectively. The 5-year LRR rates were 7.2% and 26.1% (P = 0.000), 5-year OS rates were 79.2% and 57.7% (P = 0.000) for the PMRT-HR and non-PMRT-HR groups, respectively.
Conclusion:
With the increasing of age, there is a trend of decreasing use of postmastectomy radiotherapy in high-risk breast cancer patients. Postmastectomy radiotherapy can improve the locoregional control for high-risk patients and maybe considered even for those who are > or = 65 years.
