Statistical evaluation of 71 cases (adults) of histologically confirmed supratentorial surgically treated glioblastoma multiforme seen during the period 1958 to 1973 revealed that the state of calcification as determined by roentgenography and the histological appearance of the neoplasm appeared to have a relationship with the postoperative period of survival. Postoperative adjuvant treatment, location of the neoplasm, duration of preoperative symptoms, patient's age at onset, preoperative condition, and cystic formation in the neoplasm also appeared to have a relationship, although it was slight.
