Regarding NSCLC histopathological subtypes (SCC and non-SCC), statistically significant high LOH/MSI frequency was observed for D3S1611 marker (MLH1) in SCC group (p = 0.011, χ2 = 6.47) and for D3S1583 marker (RARβ) in non-SCC group (p = 0.008, χ2 = 6.84). Here, MLH1 is linked to non-small cell lung carcinoma.
