Development of Tracheoesophageal Fistula after the Use of Sorafenib in Locally Advanced Papillary Thyroid Carcinoma: a Case Report Eyun Song, Kyung Mee Song, Won Gu Kim and Chang Min Choi Department of Internal Medicine, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Korea Sorafenib, an oral multi-kinase inhibitor, is used for the treatment of patients with radioactive iodine (RAI) refractory differentiated thyroid carcinoma (DTC) with favorable outcomes. Some unusual but fatal adverse effects are known for this drug and tracheoesophageal fistula (TEF) is one of them, which has never been reported in thyroid cancer patients. We present a successfully treated patient who had developed TEF associated with rapid tumor regression during sorafenib treatment for locally advanced papillary thyroid carcinoma (PTC). Sorafenib was discontinued and feeding jejunostomy tube was placed for nutritional support. 3 months later, the TEF had successfully healed and there was no visible fistula track or interval change of the viable tumor during 15 months of follow-up. Identifying patients at high risk for this potential complication and paying special attention when prescribing anti-angiogenics to these patients are crucial to prevent associated morbidity and mortality.

previous history of external radiation therapy which are all relevant to risk factors of TEF formation. Notably, the TEF occurrence in our current case was associated with tumor regression after sorafenib treatment and not with tumor progression. During the first month of treatment with sorafenib, her tumor size decreased dramatically. This suggests that a good response to sorafenib treatment could also be a risk factor for TEF formation when the tumor directly invades to the trachea or esophagus. Optimal treatment for TEF associated with malignancy is not established – esophageal stent or gastrotomy/jejunostomy is generally performed although it should be carefully chosen considering patient’s performance status and the location of TEF. Surgical intervention is not preferred in terms of advanced malignancy and poor performance status of the patients.

The prognosis of a patient who develops TEF as a complication of a malignancy is very poor. In the previously reported cases by Blevins et al.13), all of the patients died within 2 months of the formation of aerodigestive fistulas that resulted from hemorrhage, infection, or respiratory distress. Our present case suggests that early diagnosis of TEF and immediate therapeutic interventions for enteric feeding to prevent life threatening complications, such as aspiration pneumonia, are critical to improve the survival outcomes and quality of life. In conclusion, TEF formation can be a progressively deteriorating complication in patients administered antiangiogenic agents with tumors directly invading vital organs including esophagus and trachea, previous radiation therapy, and instrumentation of the trachea or esophagus. As sorafenib grows in importance in the treatment of RAI refractory DTC and more antiangiogenic TKIs are being developed, greater aware213 Int J Thyroidol
