“…In previous studies, prechemotherapy Hgb level was the most commonly reported risk factor for anemia on treatment or requirement for transfusion [1, 6,9,18]. Other reported risk factors include age older than 65 [11], hemoglobin decrease during the first month of chemotherapy [6], duration of chemotherapy [6], tumor type [1, 6], previous transfusions [6,7], platinum-based chemotherapy [1] and platinum pharmacokinetics [23], multiple concurrent chemotherapeutic agents [25], female sex [1], performance status (PS)>1 [24], pretreatment absolute lymphocyte count (ALC) lower than 700/μl [24]. Our data set did not permit us to test all these reported risk factors, but our results are consistent.…”
