miR-1323 Promotes Cell Migration in Lung Adenocarcinoma by Targeting Cbl-b and Is an Early Prognostic Biomarker

Conclusion: The miR-1323 promoted LUAD migration through inhibiting Cbl-b expression. High miR-1323 expression predicted poor prognosis in LUAD patients.

AbstractAnaplastic lymphoma kinase (ALK) rearrangements have been reported in 5% to 6% of non ‐small cell lung cancer (NSCLC) patients. However, the concurrent existence of twoALK fusions within the same patient have rarely previously been reported. Moreover, considering the diversities ofALK mutations, it is necessary to evaluate the response of both double and new types ofALK fusions to ALK ‐tyrosine kinase inhibitors (ALK‐TKIs). Here, we report a case of a 64‐year‐old Chinese woman who was diagnosed with lung adenocarcinoma (ADC) who concurrently harbored two types ofALK‐rearrangements, including an unreport...

Rearrangements in ROS1 oncogene, reported in 1 –2% of patients with non-small cell lung cancer (NSCLC), define a separate molecular sub-group of NSCLC [1]. Lorlatinib is a third-generation anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitor with the ability to cross the blood-brain barrier and have sub-nanomolar enzymatic efficacy in ta rgeting rearrangements in ALK and ROS1 [2]. ROS1 G2032R has been reported as the most commonly acquired mutation that mediates resistance to crizotinib therapy [3–5]; however, mechanisms that mediate lorlatinib resistance among patients with ROS1 rearrangement are rarely reported.

Approximately 2% to 8% of patients with metastatic nonsquamous non –small-cell lung cancer (NSCLC) harbor a rearrangement in the anaplastic lymphoma kinase (ALK) gene in their tumors that may render them susceptible to targeted treatment with tyrosine kinase inhibitors [1–5]. Patients with ALK-rearrangements have been described as being younger, having a histor y of never or light smoking, and being likely to have adenocarcinoma with signet ring or acinar histology, based on previous studies [3,4,6].

AbstractAnti ‐programmed cell death 1 (PD‐1) and its ligand (PD‐L1) has emerged as a novel immunotherapy for non‐small cell lung cancer (NSCLC). However, the proportion of patients who may benefit from immunotherapy is limited and the factors sensitive or resistant to immunotherapy are not completely cle ar. Therefore, to identify reliable biomarkers as predictors of clinical response and resistance to anti‐PD‐1/PD‐L1 therapies have become increasingly important. Here, we report a case of a patient with bone metastatic NSCLC, who achieved a pathologic complete response after preoperative pembr olizumab treatm...

Advanced non-small cell lung cancer (NSCLC) is a devastating disease that is incurable and associated with poor outcomes worldwide [1]. Targeted therapies with predictive biomarkers have changed the health care strategy for metastatic NSCLC patients [2]. An anaplastic lymphoma kinase (ALK) gene rearrangement is a distinct driving mutation that occurs in as many as 8% of patients with NSCLC. Of note, different fusion partners can influence the response to ALK inhibition in patients with NSCLC [3].

The development of targeted therapies has revolutionized the treatment of patients with lung cancer, especially non-small-cell lung cancer (NSCLC). Anaplastic lymphoma kinase (ALK) is a research hotspot of molecular targeted therapy for lung cancer. ALK tyrosine kinase inhibitors (TKIs) are highly effective for ALK-rearranged NSCLC-positive patients. These targeted therapies have significant clinical effects; however, they inevitably lead to acquired resistance. In previous studies, the histological transformation after ALK inhibitor treatment was mostly based on small-cell lung cancer (SCLC).

This study was undertaken to determine ICI efficacy against epidermal growth-factor receptor (EGFR)/anaplastic lymphoma kinase (ALK)/c-ros oncogene 1 (ROS1)-mutated NSCLC patients in the real-world setting. In this retrospective, multicenter study on adults with ICI-treated EGFR-mutated or ALK- or ROS1-translated NSCLCs, we analyzed clinical characteristics and outcomes: ICI-treatment duration, and progression-free survival (PFS), objective response rate, duration of response, and overall survival (OS) from immunotherapy initiation. Fifty-one NSCLC patients (mean age, 58.0 years) were included from 20 French centers: 61%...
