[Results of the radiation therapy of cancer of the true vocal cords].
A comparative estimation is given of the results of radiotherapy in 85 patients with cancer of the true vocal cords in stage T1--2N0M0 depending on focal dosage in rad and ret units. There was noted a distinct correlation between the results of the treatment and the dosage applied. The immediate clinical cure was gained in 88.2% of cases. In this group of patients an average focal dosage corresponded to 6448 +/- 72.8 rad and 1793 +/- 22.7 ret, whereas in unsuccessful radiotherapy these were 5963 +/- 158 rad and 1675 +/- 28.3 ret. A five-year cure was noted with an average dosage of 6525 +/- 87.0 rad and 1830 +/- 52.1 ret. In a group of patients with recurrences these doses were 6390 +/- 183.4 rad and 1720 +/- 34.4 ret accordingly.
