Of 740 cases of glottic cancer, a second respiratory tract tumor developed in 48. Only 14 cases would have been expected in a sample of the same age and sex distribution drawn from the general population of Ontario. Of 25 patients with second tumors in the lung, 23 are dead. Of these 23, 17 had been cured of Stage T1 glottic cancer. An actuarial method for calculating the risk of developing a second respiratory tract tumor amongst the survivors of glottic cancer is described. Of the survivors, 12% will have a second respiratory tract tumor within ten years following initial diagnosis of glottic cancer. Of patients with Stage T1 glottic cancer, 7% will die of a second respiratory tract tumor within ten years. This rate is slightly more than that for those who die of laryngeal cancer in this stage grouping. Late recurrences and/or second primary tumors in the larynx following radiotherapy are rare. Methods for reducing the risk of death from a second respiratory tract tumor are discussed. |
