Purpose And Methods:
Nowadays more people are becoming older. The median age of a patient with non-Hodgkin's lymphoma (NHL) at diagnosis is over 60 years. The incidence of NHL in elderly has increased in the last decades. Therefore, in the future, NHL will be diagnosed more often in the elderly. Data of all patients in the south-east of the Netherlands with newly diagnosed NHL between January 1991 and January 1995 were analysed in a retrospective multicentre population-based study to investigate if and how elderly patients (> 60 years) with advanced NHL (Ann Arbor Staging > or = IIB) of intermediate- and high-grade malignancy were treated. Treatment modalities applied, outcome, and causes of death were evaluated. Treatment was considered inadequate if it deviated from the standard anthracycline-containing chemotherapy (CNOP/CHOP) for a minimum of six cycles.
Results:
The entry criteria were met by 68 patients. Of these patients, 57 (83.8%) were treated and 11 (16.2%) were not treated. The treatment consisted of CHOP (36 patients), CNOP (6 patients), chlorambucil (13 patients), or COP (2 patients). Forty-two of 68 patients had adequate treatment, but 14 of 42 (33.3%) patients had a suboptimal numbers of cycles (< 6). Of 28 patients with adequate chemotherapy, only 16 had the optimal number of cycles and dose; the result is that the treatment of 76.5% (52/68) of patients differed from that of their younger counterparts. The most important reason for treatment not being optimal was high age (23%) or poor performance (35%). In the appropriately treated patients, 62.5% (10/16) had a complete response. Survival in the CHOP/CNOP-treated group was better than in other groups. The main cause of death in the total study group was NHL. The results cannot be explained by the different international prognostic index.
Conclusion:
A significant subset (76.5%) of elderly people with intermediate/high-grade NHL received suboptimal therapy, mainly because of a suboptimal performance status. However, a significant part of the patients (23%) were not treated optimally because of high age, despite a good performance. For improving the overall survival in the elderly, it is not only the schedule that is important, but also the intention to treat the elderly patient.
