On the other hand, the World Health Organization (WHO) classification (4th edition, 2017) still endorses a simple, differentiation-based histopathologic grading system of OSCC (despite its low prognostic value) and ignores factors such as tumor growth pattern and dissociation, stromal reactions (desmoplasia, local immune response), and tumor-stroma ratio. World J Surg 2018;42:3624-31. The TNM staging system is one of these. The TNM stages closely match the FIGO stages, which makes it fairly easy to convert stages between these 2 systems. Most hospitals and medical centers use the TNM system as their main method for cancer reporting.
