“…Most of the included studies originated in the United States (n = 18, 62%) (42-46, 48, 50-59, 64, 66), followed by Italy (n = 2, 7%) (69,70) and one from each of Brazil (60), the Netherlands (62), France (47), Japan (49), Norway (65), Saudi Arabia (61), Spain (63), and Thailand (67), as well as one multi-country study (58). The studies covered 11 types of cancer including non-small-cell lung cancer (n =8, 28%) (43,45,47,54,55,57,62,65), prostate cancer (n =5, 17%) (42,44,48,59,64), colorectal cancer (n = 4, 14%) (60,67,68,70), ovarian cancer (n = 3, 10%) (46,53,63), breast cancer (n = 2, 7%) (56,61), myeloma (n = 2, 7%) (49,58), melanoma (n = 1, 3%) (52), head and neck cancer (n = 1, 3%) (69), cell carcinoma of the urothelium (n = 1, 3%) (50), gastroenteropancreatic neuroendocrine tumor (n = 1, 3%) (66), and epithelial ovarian, fallopian tube or primary peritoneal cancer (n = 1, 3%) (51). Most of the interventions in these studies involved innovative anticancer drugs, including selective poly ADP-ribose polymerase (PARP)-1 and PARP-2 inhibitor (e.g., niraparib) (51,53), epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 2 tyrosine kinases inhibitor (e.g., afatinib) (55,…”
