The growing incidence of lymphomas and the increasing age of the population in western countries prompt clinicians to face more and more frequently the treatment of elderly aggressive lymphomas. Moreover, once an accurate geriatric assessment has been carried out and the patient is willing and able to receive a curative-intent therapy, the clinician has to choose among different therapeutic regimens.
In 2002, two important new achievements were reached in the treatment of aggressive lymphoma in the elderly. First, the combination Rituximab + CHOP (R-CHOP) [1] has been demonstrated to increase significantly the overall survival (OS) and event-free survival (EFS) as compared to CHOP alone. Second, the combination granulocyte colony-stimulating factor (G-CSF) + 2-weekly CHOP allows the clinician to increase dose intensity by delivering chemotherapy every 14 days and decreases the infectious complications, which elderly patients are more exposed to [2]. Two-weekly CHOP + G-CSF significantly improves the complete response and EFS when compared to the traditional CHOP (every 21 days) or to other more complex regimens. As shown in Table 1, there are no significant differences in the results achieved with R-CHOP or with 2-weekly CHOP + G-CSF.

Waiting for the ongoing trials comparing these two approaches, the current data in the literature and the estimate of expenses seem to suggest the use of 2-weekly CHOP + G-CSF in the treatment of aggressive lymphomas in the elderly.
