Purpose: This study was designed to examine the reliability and easy applicability of
new version of UICC-TNM classification (UICC, 1997) compared with old version of
UICC-TNM classification (UICC, 1992) and JRSGC (Japanese Research Society for
Gastric Cancer) classification of gastric cancer.
Materials & Method: For 1043 patients who underwent curative resection from Jan.
1992 to Dec. 1996 in Korea Cancer Center (KCCH), old version of UICC-TMN
classification and JRSGC classification were compared with the new version of
UICC-TNM classification.
Results: Correlation coefficient between topographic classification (old UICC-TNM,
JRSGC) of lymph node and numeric classification was 0.9 (P<0.05). 5-year survival
rates according to old UICC, JRSGC, new UICC classification were 94.9% at stage ¥°a;
96.6, 96.5, 97.1% at stage ¥°b; 73.8, 73.8, 73.0% at stage ¥±; 54.1, 55.8, 58.0% at stage ¥²
a; 35.5, 42.0, 36.0% at stage ¥²b; 25.9, 22.3, 23.9% at stage ¥³. 5-year survival rates of
each classification had significant difference among stages (P<0.0001), but there was no
significant difference among each classification.
Conclusion: The new version of UICC-TNM classification based on the number of
involved lymph nodes allows a staging system as reliable as the old version of
UICC-TNM and JRSGC classification. In addition, the new version of UICC-TNM
classification can be applied without methodologic problems and seems more convenient
and reproducible.
