Role of chemotherapy in long-term survival of malignant glioma (author's transl)]

Effect of chemotherapy was evaluated from the view point of postoperative survival rate in 102 consecutive cases of histologically verified glioblastomas treated during past 16 years. As a result of the study, the "additive effect" of chemotherapy on the ordinary surgical operation and radiation therapy could not be clarified. However, the effect of chemotherapy was worth to note among 6 cases which survived more than 5 years after operation. Then, combination of various treatment including chemotherapy should be repeatedly applied in individual cases of glioblastoma.
