[Cytological method in the evaluation of the results of radio- and chemotherapy of patients with laryngeal cancer].

Cytologic procedure was used for evaluating the effectiveness of conservative treatment of 223 cases of primary laryngeal neoplasms. It gave poorer results than histological or clinical ones: cases in which conservative treatment had failed as established by the three methods amounted to 66.1 +/- 6.0%, 85.5 +/- 4.4%, and 83.9 +/- 4.6%, respectively. In 14.5 +/- 4.4% of patients, cytologic findings were the only morphological evidence to make the case for radical treatment. Therefore, cytologic method should be used as adjuvant in evaluating the results of treatment of laryngeal cancer.
