Background Oral squamous cell carcinoma (OSCC), which is the most common head and neck cancer, accounts for 1%-2% of all human malignancies and is characterized by poor prognosis and reduced survival rates. WNT1-inducible signaling pathway protein 1 (WISP1), a cysteine-rich protein belonging to the Cyr61, CTGF, Nov (CCN) family of matricellular proteins, has many developmental functions and may be involved in carcinogenesis. This study investigated WISP1 single-nucleotide polymorphisms (SNPs) to elucidate OSCC susceptibility and clinicopathologic characteristics. Methodology/Principal findings Real-time polymerase chain reaction was used to analyze 6 SNPs of WISP1 in 900 OSCC patients and 1200 cancer-free controls. The results showed that WISP1 rs2929970 polymorphism carriers with at least one G allele were susceptible to OSCC. Moreover, compared with smokers, non-smoker patients with higher frequencies of WISP1 rs2929970 (AG + GG) variants had a late stage (stages III and IV) and a large tumor size. In addition, OSCC patients who were betel quid chewers and carried WISP1 rs16893344 (CT + TT) variants had a low risk of lymph node metastasis. Conclusion Our results demonstrate that a joint effect of WISP1 rs2929970 with smoking as well as WISP1 rs16893344 with betel nut chewing causally contributes to the occurrence of OSCC. WISP1 polymorphism may serve as a marker or a therapeutic target in OSCC.
