Objective: The objective of this study was to determine the association between manganese superoxide dismutase (Mn-SOD) gene C47 T polymorphism and the risk of malignant lung cancer in Iraqi smokers.
Methods: Blood samples were obtained from 260 lung cancer patients (88 females and 172 males) and 295 healthy individuals (91 females and 204 males). DNA was extracted from blood samples and the SOD2 gene was amplified using specific primers. The nucleotide sequences of the SOD2 gene were analyzed by using BLAST server at National Center for Biotechnology Information (NCBI) and the Raptorx app.
Results: TT, CT, and CC genotypes concentrations were 48.1%, 33.2%, and 18.7%, respectively, in the control group. The concentrations of TT, CT, and CC genotypes were 43.5%, 31.5%, and 25%, respectively, in the case group. There were no statistical differences between cases and controls in terms of genotype frequency of SOD2C47T polymorphism. We observed that SOD2C47T polymorphism CT genotype did not increase the risk of lung cancer development compared to those with TT genotype (OR= 0.951, 95% CI = 0.648-1.396; P = 0.798). In addition, it was observed that CC genotype did not increase the risk of lung cancer development in comparison with TT genotype ( OR=0.673, 95% Cl=0.435-1.041: P=0.075).
Conclusion: These results indicated that there was no association between SOD2C47T polymorphism and the risk of lung cancer development in Iraqi smokers.

Multiple endocrine neoplasia type 1 (MEN1) syndrome is an autosomal dominant disorder caused by a germline pathogenic variant in the MEN1 tumor suppressor gene. Patients with MEN1 have a high risk for primary hyperparathyroidism (PHPT) with a penetrance of nearly 100%, pituitary adenomas (PitAd) in 40% of patients, and neuroendocrine neoplasms (NEN) of the pancreas (40% of patients), duodenum, lung, and thymus. Increased MEN1-related mortality is mainly related to duodenal-pancreatic and thymic NEN.

This study focuses on the design, synthesis, and evaluation of benzimidazole derivatives for their anti-tumor activity against A549 and PC-3 cells. Initial screening using the MTT assay identified compound 5m as the most potent inhibitor of A549 cells with an IC of 7.19 μM, which was superior to the positive agents 5-Fluorouracil and Gefitinib.

Background: Pre-cancer onset of cachexia raises uncertainties regarding the optimal timing for early intervention in lung cancer patients. We aimed to examine changes in physical function, nutritional status, and cachexia incidence in patients with lung cancer from the initial visit to treatment initiation and determine the effect of these changes on lung cancer treatment.
Methods: This single-center retrospective cohort study enrolled patients suspected of having advanced lung cancer who visited Kansai Medical University Hospital between January and February 2023 and were definitely diagnosed with the disease.

Purpose: As microwave ablation continues to be used in patients with inoperable stage I non-small cell lung cancer (NSCLC), it is particularly important to monitor efficacy. Whether plasma ctDNA detection can predict its efficacy should be illustrated.
Methods: We recruited 43 patients with inoperative stage I NSCLC, all of whom underwent biopsy-synchronous microwave ablation (MWA).

Long-term use of low-dose aspirin has been demonstrated to reduce cancer risk, but the duration of necessary medication use remains uncertain. This study aimed to investigate the long-term chemoprotective effect of aspirin among the Chinese population. This population-based study included all aspirin users between 2000 and 2019.
