Comparison of outcomes among patients aged 80 and over and younger patients with diffuse large B-cell lymphoma: a population based study.

In this retrospective cohort study of 174 consecutive, newly diagnosed cases of diffuse large B-cell lymphoma (DLBCL), clinical and pathological variables, treatment, response and survival were compared for patients aged 80 and over (n = 40) to those under 80. Eastern Cooperative Oncology Group (ECOG) status and International Prognostic Index (IPI) were significantly worse among older patients. Standard treatment was given to only 32.5% of older versus 86.6% of younger patients, and 65% of the elderly did not receive standard therapy. At 12 months, overall and event-free survival were 51.3% (95% confidence interval [CI]: 35-66%) vs. 93% (CI: 88-97%) and 41.9% (CI: 25-58%) vs. 84.8% (CI: 77-90%), for older versus younger patients, respectively. Choice of therapy was significantly associated with survival in the elderly, and low albumin but not comorbidity score was associated with not receiving standard therapy. Patients with DLBCL aged 80 and over are distinct from all other age groups with regard to treatment tolerance. A minority can receive standard therapy, but for the majority, novel therapeutic options are needed.
