Published: January 2025

SMARCA4-deficient lung cancer, including thoracic SMARCA4-deficient undifferentiated tumors and SMARCA4-deficient nonsmall-cell lung carcinomas, is a rare and aggressive disease characterized by rapid progression and poor prognosis. This cancer was identified as a distinct entity with specific morphologic and molecular features in the 2021 WHO Classification of Thoracic Tumors. Molecular alterations in SMARCA4 are specific to this type of lung cancer. Deficiency in SMARCA4 suppresses the SWI/SNF tumor suppressor complex, driving tumor progression. Due to the lack of standardized treatment, most patients succumb to the disease within 6 months. This study provides a detailed analysis of the SMARCA4 pathway and its role in lung cancer. We analyzed potential therapeutic targets and agents to offer insights for the precise and effective treatment of SMARCA4-deficient lung cancer.

Lung cancer represents a significant global health burden, with non-small cell lung cancer (NSCLC) being the most common subtype. The current standard of care for NSCLC has limited efficacy, highlighting the necessity for innovative treatment options. Lidocaine, traditionally recognized as a local anesthetic, has emerged as a compound with potential antitumor and anti-inflammatory capabilities.

Neuroendocrine neoplasms (NENs) encompass a diverse set of malignancies with limited precision therapy options. Recently, therapies targeting DLL3 have shown clinical efficacy in aggressive NENs, including small cell lung cancers and neuroendocrine prostate cancers. Given the continued development and expansion of DLL3-targeted therapies, we sought to characterize the expression of DLL3 and identify its clinical and molecular correlates across diverse neuroendocrine and non-neuroendocrine cancers.

Objective: Addressing the rising cancer rates through timely diagnosis and treatment is crucial. Additionally, cancer survivors need to understand the potential risk of developing secondary cancer (SC), which can be influenced by several factors including treatment modalities, lifestyle choices, and habits such as smoking and alcohol consumption. This study aims to establish a novel relationship using linear regression models between dose and the risk of SC, comparing different prediction methods for lung, colon, and breast cancer.

Background: Human Lung Carcinoma (LC) is among the most diagnosed cancers across the world among those non-small cell lung cancer (NSCLC) comprises about 85%. Next Generation Sequencing based detection of mutations are now well established in molecular oncology. With the advent of modern diagnostic methods, it is now well known that there are several mutations and gene rearrangements which are associated with the development of LC.
