ABSTRACT
PURPOSE:
To assess the outcome and prognostic factors for patients with primary lymphoma of brain managed with radiation therapy between 1979 and 1988. METHODS AND MATERIALS A retrospective review was undertaken of 49 patients referred to Princess Margaret Hospital. There were 25 males and 24 females. Median age was 60 years, with a range of 17-80 years. Tumors were located supratentorially in 35, infratentorially in 10, and both in 4 patients. Single masses were demonstrated on CT brain in 36, and multiple lesions in 13 patients. Cranial irradiation was given in 48, and 11 patients received chemotherapy. All patients in this series were immunocompetent.RESULTS:
Over a follow-up range of 3-11 years of surviving patients, with a median of 6 years, 40/49 patients have died. Overall median survival was 1.4 years (17 months) and 5-year actuarial survival was 26%. Statistical analysis revealed the following significant factors Karnofsky performance status (KPS), age, and distribution pattern of disease on presenting CT brain. Five-year actuarial survival for patients with a KPS > 60 or <60 was 56% and 10%, respectively (P = 0.01); for patients with age < 60 or >60, 5-year actuarial survival was 42% and 9%, respectively (P = 0.03); for patients with solitary or multiple lesions, 5-year actuarial survival was 30% and 15%, respectively (P = 0.04).CONCLUSIONS:
We conclude that Karnofsky performance status, age, and distribution pattern on pretreatment CT of brain are significant prognostic factors in primary lymphoma of brain, and that new approaches need to be developed for these patients.
