remains the primary treatment, but optimal postoperative radiotherapy regimens are still being explored to minimize local
recurrence. This is a case of ACC of the trachea. An individualized radiotherapy regimen was meticulously planned after
surgery. This tailored approach significantly impacted the patient's outcomes.
Case Report: A 49-year-old female with history of progressive dyspnea and cough that was unresponsive to conventional
treatments over 6 months. Flexible bronchoscopy revealed an obstructing mass in the upper trachea, and biopsy confirmed
the diagnosis of adenoid cystic carcinoma. Imaging ruled out distant metastases. The patient underwent tracheal sleeve
resection, followed by adjuvant radiation therapy using Volumetric Modulated Arc Therapy (VMAT) and 6-megavoltage
(MV) radiography. The patient tolerated the treatment well, with no significant acute or late toxicities. Follow-up imaging
studies have shown no evidence of recurrence at 6 years post-treatment.
Conclusion: Tracheal ACC is a rare but distinct entity that requires prompt recognition and multimodality management
for optimal outcomes.
