As found in our study, leiomyosarcomas, undifferentiated sarcomas, and other types were more frequently PARP1‐positive than liposarcomas and myxofibrosarcomas; high expression was associated with higher pathological grade and higher mitotic count; and PARP1 expression was an independent negative prognostic feature regarding event‐free survival and disease‐specific survival. The gene discussed is PARP1; the disease is leiomyosarcoma.
