Introduction: Complete response to cabozantinib: Ø RET mutations are found in 1 -2% of ADC NSCLC Ø 70 -90% KIF 5 B-RET fusion Ø 10 -25% CCDC 6 -RET fusion Ø The natural history and management of RET mutated lung cancer are still unclear. Ø The KIF 5 B subtype showed an aggressive presentation. Ø One patient (KIF 5 B-RET) treated by cabozantinib 140 mg/day showed a rapid and durable complete response by RECIST Criteria for 8 months. Ø Grade III adverse -palmar plantar erythrodysesthesia and dysphagia. Ø To our knowledge, this is the first report of a complete response to cabozantinib for this indication. Methods: Ø A multicenter, retrospective, descriptive report of eight RET-mutated lung cancer patients, diagnosed between May 2009 and January 2015.

Ø While some RET-fusion positive LADC patients might benefit from combination chemotherapy, it may also be that the most effective targeted therapy is cabozantinib with a potential long standing complete response.
