Objectives: Nonsmall cell lung cancer (NSCLC) accounts for about 85% of all lung cancers. Asymmetric dimethylarginine (ADMA) is an emerging molecule that is highlighted in carcinogenesis and tumor progression in lung cancer. Since elevated concentrations of ADMA are observed in lung cancer patients, we aimed to explore its associations with inflammation markers and established prognostic indices.

Methods: 78 newly diagnosed non-small cell lung cancer patients who were presented with brain metastases at the initial admission and 41 Stage 1 patients with NSCLC were included in the study. ADMA concentrations among the groups were correlated. Further, the relationship between ADMA levels and the other inflammatory markers was analyzed.

Results: ADMA levels were significantly higher in the group of NSCLC patients with brain metastases than in the Stage 1 patients control group (p<0.001). A significant negative correlation was found between ADMA levels and BMI, albumin and hemoglobin (p<0.001), whereas it was positively correlated with platelet, WBC, neutrophil-to-lymphocyte ratio, RDW, RDW/albumin ratio, LDH, CRP, fibrinogen, platelet, and CRP/albumin ratio (p<0.001).

Conclusion: Increased circulating concentrations of ADMA were significantly correlated with higher NLR, CRP and LDH; which were accepted as indicators of poor prognosis in NSCLC patients. ADMA might contribute to tumor growth and dissemination via systemic inflammatory pathways.

Therapeutic hurdles persist in the fight against lung cancer, although it is a leading cause of cancer-related deaths worldwide. Results are still not up to par, even with the best efforts of conventional medicine, thus new avenues of investigation are required. Examining how immunotherapy, precision medicine, and AI are being used to manage lung cancer, this review shows how these tools can change the game for patients and increase their chances of survival.
