Prognostic indicators for oral squamous cell carcinoma: a comparison between the TNM and STNMP systems

One hundred and eighteen patients with oral squamous cell carcinoma were staged according to the TNM and STNMP systems. Although both staging systems separated patients into those with a good prognosis and those with a poorer prognosis the more sophisticated system (STNMP) did not provide any additional information. A possible explanation for this anomaly lies in the weighting used in the STNMP system.
