A retrospective study of 139 glioma patients was conducted in an effort to audit management. Factors affecting survival were studied using a Cox Proportional Hazard Model. These factors included age, sex, location, grade, type of surgery, use of radiotherapy, presenting symptoms, Karnofsky score on admission and Karnofsky score 3 months following surgery. Lower grade, high Karnofsky score on admission, radiotherapy and frontal location were associated with better survival. There was statistically insignificant evidence that the other factors had an influence on survival. Patients presenting with a poor neurological score were treated with burrhole biopsy alone. Only 10% of these patients survived more than 6 months. On the other hand, 26% of patients who had craniotomy on the basis of reasonable clinical status lived less than 6 months. Sixty-six per cent of patients in this craniotomy group were aged 60 years or over, and 66% of those aged over 60 had a Karnofsky score of less than 70. We conclude that careful judgement is required before subjecting patients aged over 60, especially those with a low Karnofsky score, to radical therapy. |
