Long-term clinical remission following radiotherapy in tracheal adenocarcinoma: Review of the published work

A 55-year-old man with tracheal adenocarcinoma presented with difficulty in breathing and cough with blood-tinged expectoration. As the patient refused surgery, he was treated with definitive radiotherapy to the neck and superior mediastinum to a total dose of 50 Gy (initially 40 Gy by AP/PA portals followed by 10 Gy with a three-field technique). He showed significant symptomatic relief to radiotherapy and defaulted from further treatment. He remained asymptomatic for 7 years, following which he developed sternal metastases and a local tumour recurrence. This case illustrates that long-term clinical remission can be achieved by radiotherapy alone in this rare histological subtype of tracheal carcinoma.
