Although the reasons for the differences in the dosing of cisplatin and 5-fluorouracil between Japanese patients and the total SPECTRUM population are uncertain, there are several potential factors that may have contributed. dose for cisplatin was 93.6 mg/m2 in Arm 1 and 97.2 mg/m2 in Arm 2, and 3732.6 and 3880 mg/m2 in Arm 1 and Arm 2, respectively, for 5-fluorouracil. Conclusions These results suggested that cisplatin/5-fluorouracil 100/1000 was feasible for recurrent/metastatic squamous cell carcinoma of the head and neck in Japanese individuals. = 327; Arm 2, = 330). Among these, 20 Japanese individuals were enrolled in the study (Arm 1, = 13; Arm 2, = 7), most of whom received 1 dosage of research medication 2-MPPA and composed the intent-to-treat and basic safety analysis pieces thus. Baseline and Demographics features are summarized in Desk?1. Age group and tumor site of origins were balanced between treatment hands; however, the percentage of sufferers with ECOG functionality position 1 was somewhat better in Arm 2 than Arm 1 (57 versus 38%), and a larger proportion of sufferers in Arm 1 than Arm 2 (54 versus 43%) acquired received prior platinum therapy. General, 7 of 20 sufferers received cisplatin for the prepared six cycles (Arm 1, = 6; Arm 2, = 1) (Desk?2). Seven sufferers turned to carboplatin from cisplatin, and six of seven sufferers who turned to carboplatin finished the prepared six cycles (Arm 1, = 3; Arm 2, = 3). Thirteen out of 20 sufferers who received 5-fluorouracil finished the prepared six cycles (Arm 1, = 9; Arm 2, = 4), in keeping with the 13 sufferers who completed 6 cycles of either carboplatin or cisplatin.

Among Japanese sufferers, the median variety of infusions (cycles) of cisplatin was 5 in Arm 1 and 4 in Arm 2; the median variety of infusions (cycles) of 5-fluorouracil was 6 in Hands 1 and 2. The mean dosage of cisplatin was 93.6 mg/m2 in Arm 1 and 97.2 mg/m2 in Arm 2; the indicate dosage of 5-fluorouracil was 3732.6 mg/m2 in Arm 1 and 3880.6 mg/m2 in Arm 2. The median comparative dosage strength (RDI) of cisplatin was 69.9% in Arm 1 and 75.8% in Arm 2. Seven sufferers (Arm 1, = 4; Arm 2, = 3) turned to carboplatin (mainly due to creatinine clearance 50 ml/min); the median RDI for carboplatin was 100% in Arm 1 and 91.3% in Arm 2. The median RDI of 5-fluorouracil was 75.1% in Arm 1 and 80.7% in Arm 2. The median variety of.
