Prognostic evaluation before operative extirpation and radiotherapy of solitary brain metastasis.
This is a retrospective study of 134 patients operated on for solitary brain metastasis at the University Hospital in Uppsala, Sweden between 1963 and 1982. All the patients underwent postoperative radiation therapy. A statistical evaluation of different prognostic factors was made in order to create a prognostic model, a so-called risk profile, to be used for future patients. The most important factors for the making of risk profiles were found to be the "histological diagnosis" followed by the "location" in the brain, then the "state on admission" and the "age" at admission in that declining order. All these variables separately and together, i.e., as risk profiles, were matched against the outcome during survival as Karnofsky's scores and against the length of survival time. The results are shown in a diagram giving the surgeon grounds for his decision-making for or against operation and also for pre-operative information.
