PARP3 and PMS1, which were genes associated with a better PFS of trabectedin, were overexpressed in L‐sarcomas and in tumors with a somatic location, whereas PARP1, a gene that correlated with worse PFS of trabectedin, was highly expressed in non‐L‐sarcomas and tumors with visceral location. This evidence concerns the gene PMS1 and sarcoma.
