Clinical Profile and Outcome of Adult Classical Hodgkin's Lymphoma: Real World Single Centre Experience.

Hodgkin's lymphoma treatment outcomes have been the true success story of modern medicine. Various data from western as well as Indian studies are available for classical Hodgkin's lymphoma (cHL). Here we report treatment outcomes from a tertiary cancer care centre in Karnataka over a 5 year period. This was a retrospective review of cHL cases aged 15 years and above diagnosed between January 2015 and December 2019 at Kidwai Memorial Institute of Oncology, Bengaluru, Karnataka, India. The case files of the patients were retrieved and relevant data was collected. Two hundred patients of cHL were included in this study. Median age was 28 years with male to female ratio of 1.56:1. B symptoms were present in 58% cases. Mixed cellularity (46.5%) was the most common histological subtype. Majority patients had advanced stage at presentation (stage III/IV) (62.5%). Extranodal disease was present in 19.5% cases. GHSG early-favourable cases were 15.5%, early-unfavourable cases were 22.0%, while 62.5% were advanced cases. The most common chemotherapy regimen used was ABVD. Eighty-three (41.5%) patients received radiation therapy. Median follow-up was 34.2 months (range 4.1-67.8). The rates for complete response (CR), partial response (PR), stable disease (SD) and progressive disease (PD) were 84.5%, 8.5%, 5.0% and 2.0% respectively. PFS and OS rate at 6 years were 69.5% and 84.1% respectively. HL is one of the malignancies with high cure rate. The treatment outcome at our centre is comparable to western data and data from other tertiary centres from India.
