PARP1 and leiomyosarcoma: Correlations existed between the two PARP1 classes (‘high’ and ‘low’) and patients’ age, tumor site, pathological type and grade, the CINSARC classification and a chromosomal instability signature, with younger patients in the ‘PARP1‐high’ class, more frequent tumor locations at the extremities, superficial trunk and head and neck, more leiomyosarcomas and other STSs and less liposarcomas and myxofibrosarcomas, more pathological grade 3, more high‐risk CINSARC tumors, and more ‘chromosomically instable’ tumors.
