The results of simultaneous radio-chemotherapy in advanced head and neck tumors

Patients suffering from locally advanced squamous cell carcinoma of the head and neck were treated with three courses of simultaneous radio-chemotherapy. Chemotherapy consisted of cis-platinum, 60 mg/m2 i.v. on day 2; 5-FU, 350 mg/m2 i.v. bolus on day 2; leucovorin calcium, 50 mg/m2 i.v. on day 2; 5-FU, 350 mg/m2/24 hrs continuously infused over 96 hrs from day 2 to day 5 and leucovorin calcium, 100 mg/m2/24 hrs continuously infused over 96 hours from day 2 to day 5 each course. Radiotherapy was administered from day 3 to day 11. 23.4 Gy were given in 13 fractions, twice a day with a minimum interval of four hours. This schedule was repeated on days 22 and 44. The total radiation dose amounted to 70.2 Gy/51 days. From 1984 to 1986, 62 patients were entered in this prospective trial. Three patients deceased due to massive hemorrhage during therapy, one patient was not eligible due to a second malignancy. 5/58 evaluable patients had a UICC-Stage III cancer, 53/58 had a UICC-Stage IV cancer. 48/58 (81%) showed a clinically complete response to therapy, 10/58 (17%) achieved partial response three months after the end of treatment. In 16/58 patients loco-regional cancer was not controlled (minimum follow-up 2 years), in 12/58 distant metastases occurred. Loco-regional control rate is estimated at 66% +/- 7% (Kaplan Maier).
