PARP1 and ovarian carcinoma: Interestingly, high PARP activity is associated with platinum sensitivity and improved PFS in epithelial ovarian cancer (EOS; Veskimae et al, 2016), and PARP‐1 positivity is associated with higher grade and complete response to first‐line chemotherapy in EOS (Godoy et al, 2011), further suggesting that assessing PARP‐1 activity has potential as a meaningful biomarker.
