Introduction: Lung cancer ranks among the foremost causes of mortality associated with cancer. Ensartinib is a highly effective oral anaplastic lymphoma kinase (ALK) inhibitor utilized in the treatment of ALK-positive lung adenocarcinoma. This report presents a case of acute renal failure attributed to the administration of ensartinib.

Background: Anaplastic lymphoma kinase () rearrangement, the most common oncogenic rearrangement in lung adenocarcinoma, occurs in approximately 5% of non-small cell lung cancer (NSCLC) patients. gene is the most common partner of rearrangement, and distinct EML4-ALK fusions differ in their responsiveness to ALK tyrosine kinase inhibitors. However, the concurrence of two rearrangements in one patient and whose response to ALK-TKIs have rarely been reported so far.

Fusion circRNA F-circEA1 facilitates EML4-ALK1 positive lung adenocarcinoma progression through the miR-4673/SMAD4/ADAR1 axis.

Cell Signal

Department of Respiratory Medicine, Jinling Hospital, Nanjing Medical University, Jiangsu Province, China. Electronic address:

Circular RNA (circRNA) can sponge miRNA participate in the tumorigenesis and progression of various cancers. We substantiate for the first time that the fusion circular RNA (F-circRNA) F-circEA1 is involved in driving the echinoderm microtubule associated-protein like 4-anaplastic lymphoma kinase variant 1-positive (EML4-ALK1) lung adenocarcinoma (LUAD) progression and the expression of the parental gene EML4-ALK1, molecular mechanisms of F-circEA1 in the EML4-ALK1 LUAD remain unknown. Bioinformatics analysis showed that only miR-4673 can bind to F-circEA1 and bind to EML4-ALK1 3'-UTR to regulate the expression of EML4-ALK1.

Risk Stratification and Adjuvant Chemotherapy for High-Risk Stage IA Lung Adenocarcinoma: The Unmet Needs.

Thorac Cancer

December 2024

Department of Thoracic Surgery, Shanghai Chest Hospital, School of Medicine, Shanghai Jiao Tong University, Shanghai, China.

Introduction: To identify high-risk patients for recurrence in resected stage IA lung adenocarcinoma and evaluate the impact of adjuvant chemotherapy (ACT) on their prognosis, as well as explore potential novel adjuvant therapies.

Methods: Consecutive stage IA patients with ≥ 5% solid or micropapillary subtypes were analyzed. A nomogram was developed using Cox proportional hazards regression to predict recurrence-free survival (RFS).

Intrathecal pemetrexed for leptomeningeal metastases in a patient with ALK-rearranged lung adenocarcinoma: a case report.

Cancer Chemother Pharmacol

December 2024

Division of Oncology, Department of Medicine, Stanford University School of Medicine, Stanford Cancer Institute, Stanford, USA.

Progressive leptomeningeal metastases (LM) are associated with intractable neurological symptoms and a poor prognosis, and effective treatment options are limited. Intrathecal (IT) pemetrexed has been shown to confer clinical benefit in lung adenocarcinoma, yet our understanding of the efficacy and safety of the treatment is limited. We report a patient with a long-standing history of leptomeningeal disease due to ALK-positive adenocarcinoma of the lung, previously controlled by increased doses of lorlatinib (125 mg/day).
