Clinical and Epidemiological Profile of Elderly Hodgkin's Lymphoma in India

Background Hodgkin's lymphoma (HL) is a curable malignancy that commonly involves the younger population. However, HL can rarely occur in the elderly population (>= 60 years) and probably has different biology as compared to the younger counterparts. There was a paucity of data on the clinical and epidemiological profile of the elderly subset with HL in Indian patients who are misdiagnosed and empirically treated as tuberculosis. We have done an analysis of this subset of elderly patients who were registered at our institute. Methods A retrospective chart analysis of HL patients who presented to our center from 2008 to 2016 was conducted. Twenty-eight patients with HL of age >= 60 years were included in this study. Results Elderly HL comprised 18.67% of the total HL patients registered during this period. The majority were male patients, and the mean age of presentation was 65.9 +/- 5.6 years. A Charlson Comorbidity Index (CCI) of >= 2 was seen in 30.77% of the patients. Among these, 84.62% of the patients presented with advanced-stage disease, and 57.69% of the patients presented with B symptoms, which was significantly associated with a high-risk international prognostic score (IPS). Histology-wise, mixed cellularity classical Hodgkin's lymphoma (MCCHL) and nodular sclerosis classical Hodgkin's lymphoma (NSCHL) were equally represented (30.76%). Of the patients, 50% had extranodal disease, with the liver being the most frequent site involved. One patient each had bone marrow involvement and bulky disease. CD30, CD15, and CD20 positivity was seen in 84.61%, 50%, and 26.92% of cases, respectively. Conclusion Among elderly HL patients, males were more commonly represented than females, and patients more often presented with advanced disease and B symptoms and less often with bulky disease and mediastinal mass. Mixed cellularity classical HL is more common in the elderly subset, and significant comorbidities are present in a higher number of elderly HL patients.
