Clinical manifestation and outcome of lung cancer patients with ocular metastasis: 16 case reports and systematic review.

Ocular metastasis is a rare type of distant metastasis of lung cancer. Limited information is available regarding ocular symptoms, diagnosis, treatment, and prognosis. We reported 16 patients diagnosed with ocular metastasis from lung cancer treated at our hospital from January 1988 to March 2024 and conducted a systematic review of 100 patients retrieved from the PubMed database from January 2014 to December 2023. A pooled analysis was performed using individual‐level patient data to generate the hazard ratio (HR) of the association between patient characteristics and overall survival. A total of 116 patients, 100 patients from the literature and 16 patients from our center, diagnosed with ocular metastasis from lung cancer were included in this study. Choroid metastasis was presented in 77 (66.4%) patients and was significantly associated with the onset of lung cancer with ocular symptoms and decreased vision; iris metastasis was significantly associated with small cell lung cancer (SCLC), high intraocular pressure, and ocular pain. Multivariate analyses revealed that males (HR, 2.488; 95% confidence interval [CI], 1.127–5.495), age ≥ 60 years (HR, 3.196; 95% CI, 1.391–7.341), and onset with ocular symptoms (HR, 4.312; 95% CI, 1.675–11.099) were significantly associated with overall survival. For non‐SCLC (NSCLC) patients, compared with chemotherapy, targeted therapy (HR, 0.238; 95% CI, 0.087–0.651) and combined therapy (HR, 0.133; 95% CI, 0.017–0.822) have greater therapeutic efficacy. Chemotherapy combined with immunotherapy and targeted therapy are more effective than chemotherapy alone for ocular metastatic NSCLC patients. For patients with targetable mutations, new‐generation tyrosine kinase inhibitors (TKIs) are preferred. [ABSTRACT FROM AUTHOR]
