Abstract
Neoadjuvant chemoimmunotherapy has demonstrated significant benefit for resectable non-small-cell lung cancer (NSCLC) excluding known EGFR/ALK genetic alterations. Recent evidence has shown that neoadjuvant chemoimmunotherapy could be clinically valuable in resectable localized driver gene-mutant NSCLC, though the data still lack robust support, especially for rare oncogenic mutations. Here, we report a patient with stage IIIA lung adenocarcinoma with a RET fusion gene and high expression of PD-L1 who underwent neoadjuvant chemoimmunotherapy and successfully attained a pathologic complete response. The patient has survived for 12 months with no recurrence or metastases after surgery. Our case suggests that this treatment strategy may be an alternative therapeutic option for resectable RET fusion-positive NSCLC patients.

Abstract
INTRODUCTION Selpercatinib is a RET selective tyrosine kinase inhibitor with nanomolar potency against diverse RET alterations, including fusions, activating point mutations, and acquired resistance mutations. Rearranged during transfection (RET) gene is a validated target in non-small-cell lung cancer (NSCLC). Selpercatinib is currently approved for adult patients with metastatic RET fusion-positive NSCLC. AREAS COVERED This review summarizes the efficacy and safety data of selpercatinib in the treatment landscape of RET fusion-positive NSCLC. EXPERT OPINION Globally considered, selpercatinib is an optimal treatment choice, in terms of both (systemic and intracranial) efficacy and safety, in patients affected by advanced NSCLC harboring RET fusions as a driver mechanism. Future challenges include the identification of the most appropriate placement for selpercatinib in the treatment algorithm of RET fusion-positive NSCLC (including early stages), the clarification of resistance mechanisms, as well as of its role in EGFR-mutant NSCLC undergoing progression during osimertinib driven by RET alterations.

Non-Small-Cell Lung Cancer Patients with Coexistence of High PD-L1 Expression and RET Fusion-Which Path Should We Follow? Case Reports and Literature Review. J Clin Med 2022; 11:jcm11061630. [PMID: 35329956 PMCID: PMC8949444 DOI: 10.3390/jcm11061630] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Revised: 03/09/2022] [Accepted: 03/10/2022] [Indexed: 02/04/2023] Open
Abstract
Pembrolizumab is widely used in first-line treatment in patients with advanced non-small-cell lung cancer (NSCLC) with high PD-L1 expression. The activity of pembrolizumab in NSCLC patients with rare molecular alterations is poorly characterised. RET gene rearrangements are identified in 1−2% of lung cancer patients. Here, we present two cases of RET-rearranged NSCLC patients with high PD-L1 expression (>50%), treated with pembrolizumab within routine clinical practice. Pembrolizumab was ineffective in both cases—single-agent immunotherapy seems to be of limited value in this group of patients. Selective RET-inhibitors, if available, are the optimal treatment for patients with RET fusion nowadays. The best sequence of the therapy is still not defined.
