Recent studies in the treatment of head and neck cancer suggest that combined chemoradiation is superior to radiation alone with regard to local-regional control. Agents that have shown activity as radiosensitizers include platinum agents and taxanes. Docetaxel is a semisynthetic taxane that affects polymerized tubulin both to promote microtubule formation and to inhibit its disassembly. As a single agent, docetaxel shows significant antitumor activity in head and neck cancer in the neoadjuvant setting. Docetaxel also exhibits potent radiosensitizing capability. Because docetaxel is a phase-specific agent, frequent administration of docetaxel offers the potential for enhancement of radiosensitization. Current trials are exploring the optimal dose and schedule of administration of docetaxel with concurrent radiotherapy in patients with head and neck cancer.
近期关于头颈部癌治疗的研究表明,在局部区域控制方面,放化疗联合治疗优于单纯放疗。已显示出放射增敏活性的药物包括铂类药物和紫杉烷类。多西他赛是一种半合成紫杉烷类药物,它作用于聚合微管蛋白,既能促进微管形成,又能抑制其解聚。作为单一药物,多西他赛在新辅助治疗中对头颈部癌显示出显著的抗肿瘤活性。多西他赛还具有强大的放射增敏能力。由于多西他赛是一种细胞周期特异性药物,频繁给药有可能增强放射增敏效果。目前的试验正在探索头颈部癌患者在同步放疗时多西他赛的最佳剂量和给药方案。
