Background: Tracheal invasion is reported to occur in approximately one-third of the patients of locally advanced thyroid cancers. There is a paucity of data in literature with regard to the long-term outcomes of thyroid cancers with tracheal invasion. Methods: A total of 37 patients from our tertiary care center underwent radical surgery for tracheal involvement for differentiated thyroid cancers between the years 2002 and 2016. The variables pertaining to the demographics, clinical presentation, imaging, operative details and histopathology reports were captured from the patient's case records and analyzed. Results: Among the 37 patients, there were 21 males and 16 females. Majority of the patients (56.8%) were >55 years of age. Surgery (tracheal resection) was performed in the primary setting in 29 patients, whereas it was performed in a recurrent setting in 8 patients. As per the Shin classification, 3 patients belonged to Shin stage 1, 3 to Shin stage 2, 16 patients to Shin stage 3 and 15 patients to Shin stage 4. There was no 30 day postoperative mortality in our cohort. The median follow-up of our cohort was 175 months. The 5-, 10-, and the 15-year overall survivals of the entire cohort were 81.7%, 47.8%, and 35.9%, respectively. Conclusion: Our series shows favorable long-term oncological outcomes of selected patients of thyroid cancers with tracheal resection and adds to the limited long-term data available in literature.
