Pathological complete response to neoadjuvant lorlatinib in a patient with unresectable ALK-Positive locally advanced non-small cell lung cancer: A case report

Anaplastic lymphoma kinase tyrosine kinase inhibitors (ALK-TKIs) have demonstrated substantial effectiveness in individuals with advanced ALK-positive non-small cell lung cancer (NSCLC). However, the controversy over using ALK-TKIs for neoadjuvant therapy in ALK-positive NSCLC has not been fully exp...

Sumario:Anaplastic lymphoma kinase tyrosine kinase inhibitors (ALK-TKIs) have demonstrated substantial effectiveness in individuals with advanced ALK-positive non-small cell lung cancer (NSCLC). However, the controversy over using ALK-TKIs for neoadjuvant therapy in ALK-positive NSCLC has not been fully explored. This case study describes the clinical progression of a patient initially diagnosed with unresectable stage III (cT1bN2M0) lung adenocarcinoma, who was later discovered to harbor an ALK mutation through next-generation sequencing. The patient underwent surgery to achieve a radical resection of the right upper lung lesion after neoadjuvant therapy with lorlatinib and a pathological complete response (pCR) was confirmed by pathological analysis. To our knowledge, it has never been reported that neoadjuvant therapy with lorlatinib resulted in pCR for an ALK-positive patient with stage III NSCLC who was initially unresectable. Therefore, our findings indicate that utilizing ALK-TKIs as neoadjuvant therapy could be considered a viable choice for ALK-positive NSCLC patients.
