Intrinsic weakness of the TNM system for classification of laryngeal cancer

All tumor classifications are compromises based upon clinical or radiological evaluation with little concern for histology and intrinsic errors in application. Laryngeal cancer is no exception, and the present UICC system is critically examined with the intention of highlighting such deficiencies and relating them where possible to prognosis. Possible lymph node and systemic metastases are also considered in the light of personal experience and any intrinsic weaknesses evaluated in relation to variations in published cure rates. No better system is proposed, for at least this system encourages more accurate recording of clinical assessment.
