Computerized staging of cancer of the maxillary sinus

There are numerous, different recommended systems for staging cancer of the maxillary sinus. No single system is known to be better than another. We have developed a method of simultaneously staging a tumour of the maxillary sinus into each of six different TNM staging classifications. This enables a comparison of the various classifications and provides a number of advantages: staging can be done quickly and easily, and is automatically standardised; it assists careful documentation of tumour extent and it ensures comparisons of like with like, which should enable a more critical and useful appraisal of the results of treatment.
