Treatment of early vocal cord carcinoma: a comparison of apples and apples.

Radiation therapy, hemilaryngectomy, and even cordectomy will cure a very large percentage of patients with early vocal cord cancer and preserve the voice. However, hemilaryngectomy and cordectomy are conceded by most surgeons to usually produce a poorer voice, compared to radiation therapy, and the operations are restricted to certain anatomical distributions. Those surgeons advocating hemilaryngectomy or cordectomy have compared their results with radiation therapy series which include a proportion of patients with lesions not suitable for voice-sparing operations. One hundred and thirty-nine patients with T 1-2 carcinoma of the vocal cords with a 2-15 year follow-up, who were treated initially by radiation therapy, were analyzed in detail by initial extent of disease. Patients were identified whose lesions were anatomically suitable for hemilaryngectomy or cordectomy, and results for these patients compared to operative results. Since the curative results with voice sparing by irradiation were at least equal, and since the quality of the voice is thought to be much better, there is little justification for recommending a major operation except in specific situations. Lesions initially suitable for voice-sparing operations which subsequently recur after irradiation can usually be treated by a voice-sparing operation.
