[Comparative evaluation of the effectiveness of radiotherapy, surgery and combined treatment of stage I-II laryngeal cancer (T1-2NoMo) based on the data of a cooperative randomized study].
During 1979-1987 269 patients with laryngeal cancer stage I-II were included into a cooperative randomized study: 111 patients had T1 and 158 patients, T2 tumor; 13% of patients showed cancer of the vestibular cord and 87% of them of the true vocal cord. 76 patients underwent surgery, 129 patients--radiotherapy, and 64 patients received combined treatment, i.e. radio- and chemotherapy (prospidine). The rate of relapses and regional metastases was 11.8 +/- 3.7% and 2.6 +/- 1.8% after surgery, 21.4 +/- 3.8% and 1.6 +/- 1.1% after radiotherapy, and 23.4 +/- 5.3% and 6.3 +/- 3.0% after combined treatment. In terms of the recurrence-free time surgical intervention showed the highest efficacy. With respect to the 5-year survival, measured in the above patients plus 42 patients operated on because of relapses and regional metastases, surgery of vocal cord cancer was effective in 100% in case of stage I, 97.4% in case of stage II; radiotherapy was effective in 91.7% in case of stage I, 88.8% in case of stage II, and combined treatment was effective in 100% in case of stage I and 70.3% in case of stage II; surgery of vestibular cord cancer stage II was effective in 100%, combined treatment in 88.9%, and radiotherapy in 68.6%. When vocal cord cancer involves the anterior commissure, ventricle, and space, preference should be given to surgery because relapses after radiotherapy were seen in 38-42%. Combined radio- and chemotherapy did not reduce the recurrence rate and therefore cannot be recommended for practical purposes.
