The relationship between the proliferative activity and clinical features in 21 cases of
recurrent astrocytic tumors were studied. The proliferative activity of tumor cell was
analysed by Ki-67 labelling index using immunohistochemistry for MIB-1 antibody.
Positive relationships were noted on clinical features, such as mean ages, time interval
between primary and secondary operation, postoperative survival, and histopathologic
grade with Ki-67 labelling indices in the primary tumors. Unlike to these,
clinicopathologic characteristics were not positively correlated in secondary recurrent
tumors. It is thus suggested that Ki-67 labelling indices would be valuable in the
estimations of clinical prognosis and histopathologic grades in the primary astrocytic
tumors but might not be in the recurrent astrocytic tumors due to change of biologic
features of tumor cell after radiotherapy and/or chemotherapy.
