Abstract:

Background: Anaplastic Lymphoma Kinase (ALK) re arrangement is observed in about 3% to 7% lung Adenocarcinoma (ADC). With the development of Next-Generation Sequencing (NGS) technology, more novel ALK fusions have been discovered, which can provide patients more opportunities to receive target therapies and achieve clinical effects. Case Report: A case of an invasive lung ADC patient with micropapillary and solid patterns harboring a novel ALK fusion (ME1-ALK) was reported. Then, thoracoscopic resection of right upper lung and cautery division of pleural adhesions were performed with general anesthesia. Considering that solid and micropapillary components accounted for 50%, nedaplatin plus pemetrexed were administrated for 4 cycles after operation with the patient's consent. The patient had no recurrence and the Disease Free Survival (DFS) was 10 months by May 17th, 2021. Conclusion: This case highlights that NGS profiling can identify more novel fusions and help solid/ micropapillary-lung ADC patients find more opportunities to receive target therapies if the patient recurrence.
