Abstract

Radiotherapy or surgery alone for advanced head and neck cancer generally yields poor results. Paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ) and carboplatin have both shown excellent radiosensitization through two discrete mechanisms, namely, blocking the cell cycle in the G2/M phase and inhibiting DNA repair. In an effort to improve locoregional control and survival, a prospective phase II study was initiated using paclitaxel 60 mg/ml and carboplatin (area under the concentration-time curve of 1), each given as a single dose weekly with concurrent conventional fractionated external beam radiotherapy. Patients were stratified into two groups: operable and inoperable/unresectable. The operable and inoperable groups received 5 weeks (45 Gy) and 8 weeks (72 Gy) of chemoradiotherapy, respectively. Patients in the operable group were evaluated with repeat biopsies from the primary site after 5 weeks. Those with a positive biopsy underwent surgery; those with a negative biopsy received 3 additional weeks of chemoradiotherapy. Thirty-four patients were entered in the operable group (28 men and six women; 40 to 71 years of age; 12 stage III and 22 stage IV). Of 26 evaluable patients, 19 (73%) had a complete clinical r...Continue Reading
