The results of radiotherapy of true vocal-cord cancer

A comparative estimation is given of the results of radiotherapy in 85 patients with cancer of the true vocal cords in stage Tsub(1-2)Nsub(o)Msub(o) 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+-25.1 ret. In a group of patients with recurrences these doses were 6390+-183.4 rad and 1720+-34.4 ret accordingly
