Aims: In order to determine whether the expression of tumour-associated carbohydrate antigens (Tn/sTn) and a representative inflammation marker, nuclear factor-κB (NF-κB), is associated with the invasiveness of oral squamous cell carcinoma (OSCC), this study has attempted to investigate the correlation of the aforementioned markers with the well-established invasive pattern grading score (IPGS) and clinicopathological parameters. Methods and results: Specimens from 143 OSCC patients with classified clinicopathological parameters and IPGS were stained immunohistochemically using anti-Tn, sTn and NF-κB antibodies. Our results showed that the expression of both Tn and NF-κB was correlated positively with staging (P = 0.036; P = 0.015), recurrence (P < 0.001; P < 0.001) and distant metastasis (P = 0.005; P = 0.009), as well as with IPGS, while the expression of sTn was correlated inversely. In addition, poor survival was associated with overexpression of Tn and NF-κB but not with expression of sTn. Conclusions: Our results indicate that a reciprocal relationship between Tn and sTn expression may serve as a reliable indicator for OSCC prognostic evaluation. In addition, expression of Tn rather than sTn may play an important role in deeply invasive OSCC via regulation of NF-κB signalling.
