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.展开更多

Methods By means of histological and immunohis tochemical techniques, MIB1 labelling index (LI) was determined in 31 pathologic specimens (DIal 6, IDC 22 and 3 benign breast lesions as control ). Results Significantly higher (P< 0. 05) MIB1 expression wus noted in breast carcinomas in contrast with benign breast lesions. MIBl LI increased with increasing tumor invasion from DCIS to IDC (P< 0. 05). Increased tendency of MIB1 LI had been also noted in according with the increased nuclear grabing (NG) of IDC. Conclusion MIBI ex- pression can faithfully reflect the proliferative activity of the breast lesions, where the breast cancers with both high MIBl LI and NG seem to have a poor prognosis.展开更多
