Fifty-nine patients with stage IV head and neck squamous cell cancer were treated with an intensive induction chemotherapy consisting of high-dose methotrexate-leucovorin, bleomycin, and cisplatin. Forty-five patients had recurrent disease following surgery and/or radiation therapy. The response rate in this group was 22%, with a median response duration of 10 weeks and a median survival of 19 weeks. The median survival in responders was 20 weeks and in nonresponders 18 weeks. Fourteen previously untreated patients (13 T4 and one T2) received identical chemotherapy followed by radiation and/or surgery. The response to chemotherapy in previously untreated patients was impressively higher (93%). These patients had a median survival of 48 weeks, and 30% survived 2 years. The initial chemotherapy did not compromise the succeeding radiation therapy or surgery. Toxicities were frequent, but generally well tolerated. It is concluded that prior surgery and/or radiation therapy compromises the efficacy of subsequent chemotherapy in head and neck cancer. Responses to intensive chemotherapy prior to surgery and/or radiation therapy are excellent in patients with T4 tumors and provides a basis for further intensive treatment in attempts to augment cure rates.
