Abstract Purpose: The application of postmastectomy radiotherapy (PMRT) in T1–2 women breast cancer patients with 1–3 positive lymph nodes has been controversial. We sought to determine the survival benefits of PMRT in the patients with T1–2 and 1–3 positive nodes.Methods: A retrospective study using the Surveillance, Epidemiology, and End Results (SEER) Regs Custom Data (with additional treatment fields) from 2001 to 2011 was performed. Patients who received PMRT were matched by the propensity score with patients who did not receive PMRT. The Overall survival (OS) and breast cancer-specific survival (BCSS) were analyzed. Results: We identified 56,725 women breast cancer patients with T1–2 and 1–3 positive nodes, and 18,646 patients were included in the analysis. After propensity score matching (1:1), with a median follow-up of 116 months, PMRT showed an increase in the OS (P = 0.018) but had no effect on the BCSS. The 10-year OS rates were 76.8% and 74.4%, and the 10-year BCSS rates were 82.8% and 82.2% for the patients who received and who did not receive PMRT, respectively. Only patients with 3 positive nodes could gain the benefit of PMRT for BCSS.Conclusion: PMRT for patients with T1–2 and 1–3 positive lymph nodes could increase the 10-year OS, and had no effect on the 10-year BCSS. Subgroup analysis indicated that only patients with 3 positive lymph nodes could benefit from PMRT for both the OS and BCSS.

Abstract Background Postmastectomy radiotherapy (PMRT) improves survival by eliminating potential occult lesions in the chest wall and lymphatic drainage area. Meta-analysis has shown that PMRT reduces mortality and local recurrence of patients with node positive breast cancer, but there is no specific data about the effectiveness of PMRT in a subgroup of patients with a high number of positive axillary lymph nodes (PALN). The aim of the study was to analyse the impact of the number of PALN on local and distant metastasis occurrence, overall survival (OS) and distant metastases free survival (DMFS) in patients treated with PMRT. Patients and methods We reviewed medical records of 129 consecutive breast cancer patients with PALN, treated at Institute of Oncology Ljubljana with PMRT between January 2003 and December 2004. We grouped patients according to the number of PALN as follows: Group 1 (less than 15 PALN) and Group 2 with more than 15 PALN. All patients received adjuvant systemic therapy according to the clinical guidelines. We analysed number of locoregional (LR) recurrences, distant metastasis, overall survival (OS), progression free survival (PFS) and DMFS. Results After the median follow-up time of 11.5 years, the Kaplan-Meier survival analysis of PALN showed significantly shorter OS (p = 0.006), shorter PFS (p = 0.002) and shorter DMFS (p < 0.001) in the group of > 15 PALN. Only one LR was found in the group of patients with more than 15 PALN. In multivariate analysis more than 15 PALN and treatment with anthracycline chemotherapy statistically significantly influenced OS and DMFS. For PFS presence of more than 15 PALN were the only independent factor of shorter survival. Conclusions Patients with more than 15 PALN have shorter DMFS, PFS and OS as compared to patients with less than 15 PALN, though they receive the same LR treatment. More studies with higher number of patients included are needed to further evaluate our findings.
