Revisit of primary malignant neoplasms of the trachea: clinical characteristics and survival analysis.

Author information

Chest Department, Veterans General Hospital-Taipei, Taiwan.


A clinical review with an analysis of prognostic factors, including clinical characteristics, histological classifications, presenting symptoms/signs and treatment modalities, was conducted in 67 patients with primary malignant neoplasms of the trachea who were seen at the Veterans General Hospital-Taipei between 1979 and 1994. The incidence of tracheal cancer was 140 times less than lung cancer during this period. Delayed diagnosis of more than 6 months after onset of symptoms occurred in one-third of the patients owing to lack of specific symptoms/signs indicative of tracheal disease. Epidermoid carcinoma was the most frequent histological type encountered and accounted for half of the cases. Surgical resection was the first choice of treatment for all patients if the disease was locally confined, except for small cell carcinoma and lymphoma. Radiotherapy was given if the patient was not suitable for surgery. Single and multivariate analyses showed that clinical symptoms and signs were not related to prognosis, except for general malaise and acute respiratory failure. Patients suffering from adenoid cystic carcinoma and mucoepidermoid carcinoma had a better prognosis than other histological diagnoses. Whether the patient received radiotherapy or not proved to be a significant prognostic factor in the patients. Patients with tracheal cancers had a poorer prognosis than those with lung cancer.
