Background. Primary tracheal tumors are a rare malignancy. Before 1960, most patients had a biopsy, followed by external orthovoltage irradiation or radon seed implantation. Advances in surgery and in radiation therapy during the past three decades have allowed more patients to undergo definitive treatment. Methods. Between 1957 and 1988, 22 patients with primary tracheal malignancy were treated with curative intent at The University of Texas M. D. Anderson Cancer Center. Five patients underwent primary surgical resection (Group 1), 5 patients had surgical resection and adjuvant irradiation (Group 2), and 12 patients had primary irradiation (Group 3). Results. Median survival times were 26 months for all patients; 16 months for Group 1; 61 months for Group 2; and 26 months for Group 3. Local control was attained in 1 of 5 patients in Group 1, 4 of 5 patients in Group 2, and 4 of 12 patients in Group 3. Among those treated with primary radiation therapy, local control was attained by three of four patients who received 60 Gy or higher and one of eight patients who received less than 60 Gy. Results of chi‐square test (P = 0.03) were statistically significant. Severe complications, including treatment‐related deaths, occurred in 2 of 5 patients in Group 1, 2 of 5 patients in Group 2, and 3 of 12 patients in Group 3. Conclusion. Radiation therapy has a role in the treatment of patients with tracheal malignancy, either as postoperative adjuvant therapy or as sole therapy for those who refuse surgery or have medically inoperable disease. Alternative methods for increasing the local administration of radiation therapy, such as endotracheal brachytherapy, should be investigated for improvement in local control.
