[Radiotherapy plus a combination of cisplatin and 5-fluorouracil for locally advanced head and neck neoplasms. Study of feasibility and preliminary results].
In March 1989 we started a feasibility study of combined radio-chemotherapy in patients with locally-advanced head and neck cancer. The first phase of treatment consisted of conventional radiotherapy (2 Gy/day, 5 days/week for a total dose of 70 Gy to primary tumor and +/- 50 Gy to nodes) and cisplatinum (20 mg/m2, i.v., for 4 days) +5FU (200 mg/m2, i.v., for 4 days) every 4th week, during radiant sessions. The second phase of treatment was started about one month after the end of simultaneous chemotherapy and radiotherapy: patients in complete remission received 1 more cycle of chemotherapy, as consolidation, while patients in partial remission received two more cycles of chemotherapy. Non-responding patients received no more chemotherapy. During the second phase the days of cisplatinum and 5FU were 5. Up to April 1990, 17 patients have been included in the study. They were stage III (64%) and IV (36%). The mean administered dose of radiotherapy was 66 Gy (range: 60-70 Gy) to primary tumor and 60 Gy (range: 40-70 Gy) to nodes. The total number of chemotherapy cycles administered during radiant sessions was 37, the mean number of cycles was 2 (range: 1-3), with 100% dose percentage. The interval between cycles was 3 weeks in 84% of patients. The relationship between number of cycles administered and planned cycle was 37/39 (feasibility: 95%). Acceptability was 100% (no patient refused the treatment). Feasibility of the second phase was 77% and acceptability 90% (1 patient refused the treatment). Toxicity was moderate during the first and the second phases. After the first phase 14/15 evaluable patients (92%) had major response (complete remission: 46%). After the second phase 10/10 evaluable patients had a complete remission. In conclusion, this combined treatment is very easy to administer, and very well accepted. Moreover, it yields a high number of objective responses.
