Principal component analysis (PCA) of HNSCC samples using the angiogenesis gene list or the entire gene list. The PCA clustering using the angiogenesis gene list revealed the presence of two major clusters of patient samples along with a third distinct, solitary sample (a). PCA analysis using the entire data set demonstrated less distinct clustering suggesting that the angiogenesis-related genes represented a potential key program for distinguishing between tumors (b).
