Paclitaxel, 5-fluorouracil, hydroxyurea, and concomitant radiation therapy for poor-prognosis head and neck cancer

A series of phase I and phase II studies investigating multiagent concomitant chemoradiotherapy in patients with poor-prognosis head and neck cancer have been conducted at the University of Chicago. Drug combinations initially included 5-fluorouracil (5-FU) and hydroxyurea, with the more recent addition of cisplatin; in the most recent trial, paclitaxel was substituted for cisplatin. The primary end point of these trials was definition of maximum tolerated doses in combination with radiation therapy. All radiation therapy was given concomitantly with chemotherapy on an every-other-week schedule (total dose,
