This study was aimed to estimate pre-surgical serum CD44 concentration and assess the possibility of using it as a non-invasive prognostic tool in oral cancer.
Crosstalk between Raf-MEK-ERK and PI3K-Akt-GSK3β signaling networks promotes chemoresistance, invasion/migration and stemness via expression of CD44 variants (v4 and v6) in oral cancer.
Among 552 betel-nut chewers, CD44 polymorphisms carriers who smoked had a 4.23-16.11-fold greater risk of having oral cancer compared to those who carried the WT but did not smoke.
