Like nearly all other forms of NSCLC, the prognosis of<unk>  squamous<unk>  carcinoma is quite poor. Although case numbers tend to be rather small, and the published studies statistically underpowered, much (but not all) evidence suggests that<unk> s may have a somewhat worse prognosis than "conventional" (i.e. non-basaloid) squamous<unk>  lung carcinomas. As survival has been noted to be worse in<unk>  variants at earlier tumor stages (i.e. Stages I and II), the decreased survival could be attributable to earlier distant metastasis appearing during the natural history of these tumors, as compared to other squamous<unk>  carcinomas and NSCLCs in general.
