[Chemo-radiotherapy in advanced head and neck tumors. Personal experience].
From January 1981 through December 1983, 49 untreated patients with locally advanced head and neck cancers were randomized in two groups to receive different radiochemotherapy regimens. Group A, including 29 cases, received 4 cycles of induction chemotherapy with Bleomycin, Methotrexate and Hydroxyurea before definitive external radiotherapy (60 Gy); group B, including 20 patients, received the same total dose of radiotherapy but the 4 cycles of chemotherapy, as described above, were administered between the 20- and the 40-Gy doses. Both groups were compared with a control group treated in the same period with radiotherapy (60 Gy) alone. The response to treatment was evaluated at the end of chemotherapy or radiotherapy alone and at the end of combined regimens. Long-term survival rates were analyzed for all groups relative to complete tumor response, disease-free interval and time to disease progression. In our experience the radio-chemotherapy combination, according to the described schedules, failed to improve both local control and overall survival; the comparison with the control group does not suggest that induction or intercalated chemotherapy can increase long-term survival even if initial complete and partial response rates are high.
