“…3,7,10,12 The other guidelines, NCCN, ESMO and ASCO did not mention gender as a risk factor. 3,[6][7][8][9][10][11][12] Other risk factors included concomitant chemotherapy such as alkylating agents, antimicrotubular agents or immuno-and targeted therapies, were considered risk factors in ESC, while ASCO, SEOM, SIOG and ESMO mentioned trastuzumab only NSW mentioned that any other potentially cardiotoxic drugs such as trastuzumab, paclitaxel, streptozocin, cyclosporin, dacarbazine, dactinomycin, etoposide, cyclophosphamide, ifosfamide, mitomycin, melphalan, vincristine and bleomycin may increase the risk of cardiotoxicity. [6][7][8][9][10] All guidelines considered age as a risk factor, but there were discrepancies with regards to the age at highest risk; ESMO indicates a range of younger than 10 years and older than 75 years, while ESC indicates a range of younger than 18 years and older than 65 years as high risk, NCCN only mentioned age above 65 years, SEOM mentions age younger than 15 years and older than 65 years, and ASCO mentions only older than 60 years.…”
