摘要
The relation between morphometric grades (M grading) of 84 cases of bladder tumor and prognoses was evaluated. The results shown that the higher the M grading, the lower the survival rate and the higher the recurrence rate. As the M grade increases, the tumor has partial of total absence of ABO(H) antigens of tumor cell surface and could be accompanied with muscular invasion. When recurring, the tumor has a poor prognosis if M grading increases from lower to higher grades. The morphometric grading system is able to make a quantitative pathologic diagnosis and can predict the biological behavior of bladder tumors.
