OBJECTIVE: The aim of this study was to compare the usefulness of a new universal grading system for @entity43 proposed by Shimizu et al. ( @entity5 82 (1998), 893; Gynecol. Oncol. 70 (1998), 2) with that of the FIGO grading system as a prognostic factor of @entity43 . METHODS: We reviewed all paraffin-embedded tissues of @entity43 obtained from 130 @entity1 who underwent initial treatment including primary surgery in our hospital between January 1990 and December 2000. The scores of the specimens were obtained according to both the universal grading system and the FIGO grading system. RESULTS: Both the FIGO grading system and the universal grading system worked as significant prognostic indicators. @entity1 with Grades 1 and 3 of the universal grading system had high and low 5-year survival rates, respectively, compared to those of the FIGO grading system. Inconsistencies in histologic grade between the FIGO and universal grading systems were observed in 22 @entity1 . The positive rate of lymph node @entity3 in @entity1 with Grade 3 of the universal grading system was significantly high compared to those of the FIGO grading system (P = 0.03). @entity1 with Grade 3 of the universal grading system with @entity41 of not less than 2 cm in diameter were observed more frequently than those of the FIGO grading system. C4ONCLUSION: The universal grading system was superior to the FIGO grading system in terms of the prediction of @entity5 such as the potential of lymph node @entity3 and invasion and the adaptability to clear cell @entity5 .

Comparison of the usefulness between a new universal grading system for XXXX and the FIGO grading system.
