Early-stage Hodgkin lymphoma is a highly curable malignancy. However, the outcomes for elderly patients have remained suboptimal. We conducted a retrospective study using the National Cancer Database to assess the therapies used for elderly patients with early-stage Hodgkin lymphoma from 2004 to 2012. Our results showed improved survival with combined chemotherapy and radiation therapy. However, the usage of the latter remains suboptimal.Background:
The outcome for early-stage (I/II) Hodgkin lymphoma (HL) has improved significantly during the past few decades. However, older age (≥ 60 years) has continued to be associated with poor outcomes, and a paucity of data is available defining the optimal treatment regimens. In the present study, we sought to identify the practice patterns and outcomes in elderly patients with early-stage HL using the National Cancer Database.Materials and Methods:
We performed a retrospective study of patients aged 60 years with early-stage classic HL diagnosed from 2004 to 2012. The overall survival (OS) of patients undergoing chemotherapy (CT), radiation therapy (RT), or CT plus RT were compared. Kaplan-Meier curves of OS for individual therapy were constructed and compared using the log-rank test. Multivariate analysis for predictors of mortality was conducted using the Cox proportional hazard method.Results:
A total of 3795 patients were included in the analysis. At baseline, 41% patients had stage I disease. Of the 3795 patients, 51% underwent CT, 16% underwent RT, and 33% underwent CT plus RT. With a median follow-up duration of 40.4 months, the unadjusted OS rates for patients receiving CT, RT, or CT plus RT were 58.1%, 54%, and 77.7%, respectively (P < .0001). On multivariate analysis, CT plus RT improved OS compared with monotherapy.Conclusion:
In older patients (age ≥ 60 years) with stage I/II HL, the combination of CT plus consolidative RT resulted in improved OS compared with monotherapy. However, the use of combination therapy in this age group seems suboptimal. This could be, in part, secondary to comorbidities limiting the use of CT plus RT in the elderly.
