Recent meta-analysis published by Feng et al. analyzed seventeen studies and reported statistically significant reduction in risk of lung cancer by 8% when circulating 25-VD is at 10 nmol/L, this benefit was seen in both Caucasian and Asian population. To our knowledge, there have been no studies looking at influence of concurrent vitamin D or aspirin intake on outcomes in ALK, ROS and EGFR pos NSCLC treated with tyrosine kinase inhibitors.
