[Clinical studies on eleven patients with nasal and paranasal lymphoma, with special reference to staging evaluation].
Adequacy of applying Ann Arbor classification and TNM classification to evaluate extent of disease in extranodal lymphoma was assessed in patients with nasal and paranasal lymphoma. Ann Arbor classification proposed to evaluate extent of Hodgkin's disease was not considered to be good at assessing extranodal local lesions. TNM classification was superior to Ann Arbor classification in terms of the correspondence with survival. Patients with nasal and paranasal lymphoma of T3 and T4 stage (TNM classification) were prone to develop bone marrow and CNS spread.
