The effect of adjuvant radiotherapy on M0 adenoid cystic carcinoma of the breast: a retrospective cohort study based on SEER data.

ABSTRACT:

Background

Adenoid cystic carcinoma of the breast (ADCC) is a rare histologic subtype of breast cancer. Currently, there are no universally accepted guidelines for the treatment of ADCC. This study aimed to evaluate the association between adjuvant radiotherapy (RT) and the survival outcomes, including overall survival (OS) and breast cancer-specific survival (BCSS), of patients with non-metastatic (M0) ADCC following breast-conserving therapy (BCT).

Methods

We identified patients diagnosed with breast ADCC between 2000 and 2021 using the Surveillance, Epidemiology, and End Results (SEER) database. The inclusion criteria were as follows: (I) an International Classification of Diseases for Oncology-3 histology code of 8200/3; (II) complete clinicopathological data; (III) diag
