Hodgkin lymphoma (HL) is an uncommon malignancy of B-cell origin. Classical HL (cHL) and nodular lymphocyte–predominant HL are the 2 main types of HL. The cure rates for HL have increased so markedly with the advent of modern treatment options that overriding treatment considerations often relate to long-term toxicity. These NCCN Guidelines Insights discuss the recent updates to the NCCN Guidelines for HL focusing on (1) radiation therapy dose constraints in the management of patients with HL, and (2) the management of advanced-stage and relapsed or refractory cHL.

The NCCN Clinical Practice Guidelines in Oncology for Hodgkin Lymphoma (HL) provide recommendations for the management of adult patients with HL. The NCCN panel meets at least annually to review comments from reviewers within their institutions, examine relevant data, and reevaluate and update their recommendations. Current management of classic HL involves initial treatment with chemotherapy alone or combined modality therapy followed by restaging with PET/CT to assess treatment response. Overall, the introduction of less toxic and more effective regimens has significantly advanced HL cure rates. This portion of the NCCN Guidelines focuses on the management of classic HL.

The NCCN Clinical Practice Guidelines in Oncology for Hodgkin Lymphoma (HL) provide recommendations for the management of adult patients with HL. The NCCN Guidelines Panel meets at least annually to review comments from reviewers within the NCCN Member Institutions, examine relevant data, and reevaluate and update the recommendations. These NCCN Guidelines Insights summarize recent updates centered on treatment considerations for relapsed/refractory classic HL.

This portion of the NCCN Guidelines for Hodgkin lymphoma (HL) focuses on the management of classical HL. Current management of classical HL involves initial treatment with chemotherapy or combined modality therapy followed by restaging with PET/CT to assess treatment response using the Deauville criteria (5-point scale). The introduction of less toxic and more effective regimens has significantly advanced HL cure rates. However, long-term follow-up after completion of treatment is essential to determine potential long-term effects.

Hodgkin lymphoma (HL) is an uncommon malignancy involving lymph nodes and the lymphatic system. Classical Hodgkin lymphoma (CHL) and nodular lymphocyte-predominant Hodgkin lymphoma are the 2 main types of HL. CHL accounts for most HL diagnosed in the Western countries. Chemotherapy or combined modality therapy, followed by restaging with PET/CT to assess treatment response using the Deauville criteria (5-point scale), is the standard initial treatment for patients with newly diagnosed CHL. Brentuximab vedotin, a CD30-directed antibody-drug conjugate, has produced encouraging results in the treatment of relapsed or refractory disease. The potential long-term effects of treatment remain an important consideration, and long-term follow-up is essential after completion of treatment.

The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Hodgkin Lymphoma (HL) include the clinical management of classical HL and lymphocyte-predominant HL (LPHL). Major changes have been incorporated into these guidelines since their inception. In the 2012 NCCN Guidelines for HL, PET scans are not recommended for interim restaging of patients with stage I to II favorable disease. After reevaluating the available evidence on the use of interim PET imaging, the panel recommends the use of diagnostic CT scan of involved sites for interim restaging after completion of chemotherapy for this group of patients. Maintenance rituximab for 2 years is included as an option for patients with stage IB to IIB or stage III to IV LPHL treated with rituximab alone in the first-line setting. Brentuximab vedotin is included as an option for patients with progressive disease or relapsed disease after second-line chemotherapy or high-dose therapy with autologous stem cell rescue.

The introduction of targeted therapies has revolutionized treatment and improved outcomes in patients with leukemias and lymphomas. However, many patients experience relapse caused by the persistence of residual malignant cells. Cytogenetic and molecular techniques are increasingly being used to assess and quantify minimal residual disease (MRD). The emergence of advanced technologies has led to the discovery of multiple novel molecular markers that can be used to detect MRD and predict outcome in patients with leukemias and lymphomas. Gene expression signatures that predict clinical outcomes in patients with non-Hodgkin's lymphoma have been identified. In chronic myelogenous leukemia, molecular monitoring has become more important in assessing response and detecting resistance to therapy. In acute leukemias, several new markers have shown potential in prognostication and monitoring treatment. In leukemias and lymphomas, microRNAs have been identified that may be useful in diagnostics and prognostication. To address these issues, the National Comprehensive Cancer Network (NCCN) organized a task force consisting of a panel of experts in leukemia and lymphoma to discuss recent advances in the field of molecular markers and monitoring MRD.

Cure rates for Hodgkin disease/lymphoma have increased to such an extent that the overriding treatment considerations often relate to long-term toxicity, especially for patients with early- or intermediate-stage disease. Current management programs are based on comprehensive clinical staging followed by combined modality therapy for patients with favorable and intermediate prognosis, or chemotherapy alone for patients with advanced disease. Relapse is uncommon, but secondary management with peripheral stem cell transplantation may be effective. The excellent prognosis for these patients mandates careful long-term follow-up to detect late treatment effects. For the most recent version of the guidelines, please visit NCCN.org
