A clinical statistical study of lung cancer patients in Japan with special reference to the staging system of TNM classification: a report from the Japan Joint Committee of Lung Cancer associated with the TNM System of Clinical Classification (UICC).
In 1978, after having conducted clinical field trials, the TNM Committee of Union Internationale Contre le Cancer (UICC) decided on an uniform system for the classification of lung cancer. The Japan Joint Committee of Lung Cancer (JCC) has continued to conduct field studies recommended by UICC, and since then has completed its third series carried out at 149 participating institutions. In this third series, the case records of 4,931 lung cancer patients were submitted for analysis. A clinical staging system of these findings was then set up, arranged in the TNM classification. As a result of this work, some improvements were made in the staging system. And JCC will now propose these changes, given as follows, to UICC for consideration: Occult Cancer: TX N0 M0 Stage I: T1 N0 M0, T2 N0 M0 Stage II: T0 N1 M0, T1 N1 M0, T2 N1 M0 Stage III: T3 N0 M0, T3 N1 M0, Any T N2 M0 Stage IV: Any T, Any N M1 The factors influencing the prognosis of patients with lung cancer (Yoshimura et al., 1982 (b)) (which include age, sex, histological type, modality of treatment and type of clinical staging used) were then re-evaluated. The results of this evaluation suggest an improved 5-year survival rate when using multi-modality treatment.
