Post‐radiotherapy vascular lesions of the breast: immunohistochemical and molecular features of 74 cases with long‐term follow‐up and literature review

Abstract

Our findings confirm that BLAP and AVL have a good prognosis, and that post-RT AS prognosis is strongly related to histological grading. On molecular analysis, AVL and post-RT AS shared HRAS and hTERT mutations, suggesting a relationship between the two lesions.
