Pathologists currently use the World Health Organization (WHO) modification of the Revised European-American Lymphoma (REAL) classification for the histologic classification for adult Hodgkin lymphoma (HL).[1,2]
In general, the use of combined chemotherapy and low-dose involved-field radiation therapy (LD-IFRT) broadens the spectrum of potential toxicities, while reducing the severity of individual drug-related or radiation-related toxicities. Current approaches use chemotherapy with or without LD-IFRT. The volume of radiation and the intensity/duration of chemotherapy are determined by prognostic factors at presentation, including presence of constitutional symptoms, disease stage, and bulk.
Nodular lymphocyte-predominant HL is a clinicopathologic entity of B-cell origin that is distinct from classic HL.[3,4,5] The typical immunophenotype for lymphocyte-predominant disease is CD15-, CD20+, CD30-, CD45+, while the profile for classic HL is CD15+, CD20-, CD30+, CD45-. Patients with lymphocyte-predominant disease have earlier-stage disease, longer survival, and fewer treatment failures than those with classic HL. Lymphocyte-predominant HL is usually diagnosed in asymptomatic young males with cervical or inguinal lymph nodes but usually without mediastinal involvement. Based on retrospective analyses spanning several decades and because of the rarity of this histology, limited-field radiation therapy is the most common treatment approach for patients with early-stage disease.[7,8,9]
The REAL Classification of Lymphoid Neoplasms proposed separating nodular lymphocyte-predominant HL (CD15-, CD20+, CD30-) from lymphocyte-rich classical HL (CD15+, CD20-, CD30+), on the basis of these immunophenotypic differences.[2,10] The largest retrospective report of 426 cases showed no significant difference in clinical response or outcome to standard therapies for these two subgroups.[Level of evidence: 3iiiA] Of interest, with a median follow-up of 7 to 8 years, more patients died of treatment-related toxic effects (acute and long-term) than from Hodgkin recurrence. Limitation of radiation dose and fields and avoidance of leukemogenic chemotherapeutic agents, along with watchful waiting policies, should be investigated for these subgroups.[12,13]
