Neoadjuvant therapy with cisplatin/fluorouracil vs cisplatin/UFT in locally advanced squamous cell head and neck...

This study compared the activity and toxicity of fluorouracil (5-FU)/ cisplatin with the combination tegafur and uracil (UFT)/cisplatin in the neoadjuvant treatment of locally advanced-stage III or IV (MO)-head and neck cancer. A total of 67 patients were randomly assigned to treatment with cisplatin 100 mg/m2 on day 1 followed by either a continuous infusion of 5-FU 1,000 mg/m2/day on days 2 through 6 (group 1) or oral administration of UFT 300 mg/m2/day on days 2 through 20 (group 2). Both treatments were repeated every 21 days for four cycles. Responding patients received locoregional standard radiotherapy (50 to 70 Gy) after chemotherapy. Group 1 was comprised of 34 patients, 30 of whom were men, with a median age of 57.5 years; 79% of this group had a Karnofsky performance status of 90% to 100%; 70% had a squamous and 29% an undifferentiated histology. The majority (85%) had stage IV disease. Of the 33 patients in group 2, 29 were men. The median age was 56 years. Most (88%) had a performance status of 90% to 100%. More patients had a squamous than an undifferentiated histology (82% vs 18%) and most (88%) had stage IV disease. Overall response in group 1 was 73% (21% complete) compared with 79% (18% complete) in group 2. At a median follow-up of 84 months, no significant differences have emerged in overall survival, 15 vs 37 months, or time to progression, 8.5 vs 14.5 months, for groups 1 and 2, respectively. Toxicity was also similar, except for phlebitis, which occurred significantly more often in group 1 (71% vs 9%). Cisplatin/UFT was as effective as the classic cisplatin/5-FU regimen and has the advantages of outpatient oral administration and a lower incidence of phlebitis.
