Background We hypothesized that incorporation of tumor thickness into the tumor–node–
metastasis (TNM) system will provide better prognostic information. Tumors were …

Depth of invasion (DOI) and tumour thickness (TT) are known prognostic indicators in oral
squamous cell carcinoma (OSCC), but varying definitions have been used by pathologists …
