A long-term survivor after aggressive treatment for tracheal adenoid cystic carcinoma: A case report

A 61-year-old male underwent a tracheal resection and reconstruction with omentopexy for the treatment of tracheal adenoid cystic carcinoma. Postoperatively, he received radiotherapy for a microscopic residual tumor of the tracheal margin. It recurred with pulmonary metastasis and para-esophageal lymph nodal metastasis at 7 years and 10 months after the initial operation. A wedge resection and concurrent chemoradiotherapy were carried out to treat the recurrence, followed by consolidation chemotherapy. Eleven months later, he developed a second recurrence with a right hilar lymph nodal metastasis, and thereafter he also suffered from a left hilar lymph nodal metastasis. As a result, he received concurrent chemoradiotherapy twice over a 3- year period. One year and 2 months later, a new pulmonary metastasis appeared, and a wedge resection was carried out. Although the patient had five instances of recurrence over an 11-year period during his treatment course, he is presently doing well as a result of appropriate local treatments using multiple modalities.
