[Chemo-radiotherapy for head and neck cancer].

| Abstract |
Many randomized trials have investigated the effect on survival of induction chemotherapy; none however, has demonstrated improved survival. A study of the Department of Veterans Affairs Laryngeal Cancer Study Group demonstrated the feasibility of induction CDDP/5-FU plus surgical salvage as an alternative to initial laryngectomy, but it did not include a radiation-alone treatment arm. Thus, a three-arm trial (R 91-11) was needed to compare the regimen of induction chemotherapy plus surgical salvage treatment with radiation alone and with concurrent chemo-radiation, to determine whether the addition of chemotherapy led to better results than conventional radiation alone. R 91-11 data revealed that concurrent chemo-radiation significantly increased the time to laryngectomy and chemotherapy suppressed distant metastasis, but there was no difference in overall survival. Single-agent docetaxel is known to induce a response in 22-45% of patients with recurrent squamous cell cancer of the head and neck. When used in combination with CDDP, response rates of between 40 and 54% have been reported. Increased expression the epidermal growth factor receptor (EGFR) is reported in head and neck cancer. Anti-EGFR monoclonal antibody is associated with decreased cell proliferation, inhibition of metastasis and angiogenesis, and it has a synergistic effect with chemotherapy or radiotherapy. It is hoped that further advances will lead to greater realization of the therapeutic potential of these compounds as anticancer agents.
