Interestingly, a recent report evaluated PDGFRα, PDGFRβ and PDGF-CC expression of tumor and/or stromal cell in primary tumors (N = 489), synchronous lymph node metastases (N = 135) and asynchronous recurrences (N = 39) using immunohistochemistry in a prospectively maintained cohort of BC patients [56]. The gene discussed is PDGFRB; the disease is breast cancer.
