Relapsed and refractory classical Hodgkin lymphoma: the decisions you may face

5 treatment settings, 5 with more than one named option. Each section lays out the options the standard of care names, what each is for, the trials behind them with their recorded results, the side effects and cautions on record, and questions to ask. Built from the cancer page's standard-of-care rows; nothing here is advice for your case.

Second line

Salvage before transplant

Platinum-based chemotherapy (ICE, DHAP, GVD) increasingly combined with brentuximab vedotin or pembrolizumab, or brentuximab vedotin with nivolumab, to reach PET-negative remission.

The options, in plain words

The ADC that made the modern field credible (2011), for Hodgkin lymphoma and CD30+ lymphomas.

Nivolumab was the second PD-1 blocker and is often combined with ipilimumab. Long-term data show about half of advanced melanoma patients alive at 10 years on the combination.

Pembrolizumab is a PD-1 blocking antibody approved in more than 40 settings, from melanoma and lung cancer to the first tumour-agnostic approval for mismatch-repair-deficient tumours in 2017, and before and after surgery in triple-negative breast cancer. A subcutaneous form arrived in 2025, and it is the backbone partner for ADCs and personalised neoantigen vaccines.

A versatile chemotherapy used in pancreatic, bladder, lung, ovarian, breast and biliary cancers, in nasopharyngeal cancer, and as a bladder instillation.

FDG PETStandard of care

FDG PET is the standard PET scan. A radioactive sugar shows which tissues are burning glucose fast, which most cancers do.

Questions to ask about this decision
  1. Between Brentuximab vedotin, Nivolumab, Pembrolizumab and the other options, which do you recommend for me, and what about my case would make you choose differently?
    Why: Guidelines list several reasonable options; the choice turns on details of your tumour, your health and your priorities.
  2. What is each option trying to achieve: cure, long control, or relief of symptoms, and over what time?
    Why: The aim shapes how much side effect and disruption is worth accepting.
  3. Which side effects of Brentuximab vedotin or Nivolumab are most likely for me, which are reversible, and which would make us stop?
    Why: The recorded rates below come from labels and trials; your own risk depends on dose, other medicines and your health.
  4. What happens if I delay, or decline this step for now? Is the decision reversible?
    Why: Some decisions can wait for a second opinion or a trial slot; others cannot. Knowing which is part of the choice.
  5. Does your recommendation follow the current guideline (NCCN Guidelines: Hodgkin Lymphoma), and if it departs from it, why?
    Why: Departures from guidelines are sometimes right for an individual; they should be explained.
  6. For my situation (salvage before transplant), which of the standard options do you recommend and why?
    Why: Guideline options include: Platinum-based chemotherapy (ICE, DHAP, GVD) increasingly combined with brentuximab vedotin or pembrolizumab, or brentuximab vedotin with nivolumab, to reach PET-negative remission.
  7. Am I a candidate for Brentuximab vedotin, Nivolumab, Pembrolizumab or related drugs, and what side effects should I expect?
    Why: Knowing the expected toxicities helps you plan work, family, and supportive care.

Other settings

Consolidation

2 options

High-dose chemotherapy with autologous stem cell transplantation for chemosensitive relapse; brentuximab vedotin maintenance for a year in high-risk patients (AETHERA).

The options, in plain words

Autologous stem cell transplant collects the patient's own blood-forming stem cells, gives melphalan or another chemotherapy at a dose that would otherwise destroy the marrow, then returns the cells to rebuild it. It is standard consolidation in myeloma and for relapsed lymphoma, though CAR-T has displaced it in early-relapsing large B-cell lymphoma.

  • Permits dose intensity impossible otherwise
  • Decades of outcome data
  • Widely available

The ADC that made the modern field credible (2011), for Hodgkin lymphoma and CD30+ lymphomas.

The evidence behind it
The main trade-offs on record
  • Treatment-related mortality ~1-2% (myeloma) to higher in children
  • Infertility, second malignancies, prolonged cytopenias
  • Being challenged by CAR-T and MRD-guided deferral

Second line

Relapse after transplant

Pembrolizumab (KEYNOTE-204) or nivolumab (CheckMate 205); brentuximab vedotin if not previously given; PD-1 antibodies in China include penpulimab and others.

The options, in plain words

Pembrolizumab is a PD-1 blocking antibody approved in more than 40 settings, from melanoma and lung cancer to the first tumour-agnostic approval for mismatch-repair-deficient tumours in 2017, and before and after surgery in triple-negative breast cancer. A subcutaneous form arrived in 2025, and it is the backbone partner for ADCs and personalised neoantigen vaccines.

Nivolumab was the second PD-1 blocker and is often combined with ipilimumab. Long-term data show about half of advanced melanoma patients alive at 10 years on the combination.

The ADC that made the modern field credible (2011), for Hodgkin lymphoma and CD30+ lymphomas.

Penpulimab is a Chinese PD-1 antibody approved in the US in 2025 for nasopharyngeal carcinoma, the second after toripalimab.

Immune checkpoint inhibitors are antibodies against CTLA-4, PD-1 or PD-L1 that release the brakes on T cells so they attack the cancer. They are approved in more than 20 tumour types and produce lasting, sometimes curative responses that chemotherapy rarely does, but most patients do not respond and autoimmune side effects are the cost.

Other settings

Failure of PD-1 antibodies and brentuximab

Allogeneic transplantation for fit patients; bendamustine, gemcitabine or everolimus; CD30 CAR T cells and bispecific antibodies in trials.

The options, in plain words

Allogeneic stem cell transplantation replaces a patient's blood system with a donor's after conditioning chemotherapy, so donor immune cells hunt down leukaemia left behind. It remains the only cure for adverse-risk acute myeloid leukaemia, high-risk acute lymphoblastic leukaemia and Richter transformation, at the price of graft-versus-host disease.

  • Curative for otherwise incurable leukaemia
  • Graft-versus-leukaemia is an antigen-agnostic immune therapy

A versatile chemotherapy used in pancreatic, bladder, lung, ovarian, breast and biliary cancers, in nasopharyngeal cancer, and as a bladder instillation.

An mTOR-blocking pill that doubled progression-free time with exemestane in 2012 and is now paired with the oral SERD giredestrant.

The evidence behind it
The main trade-offs on record
  • Treatment-related mortality 10-20%
  • Chronic GVHD
  • Relapse remains the main cause of failure
  • Avoid grapefruit. Live vaccines are contraindicated.
  • 7.5 mg (mild), 5 mg (moderate), 2.5 mg (severe).

Other settings

Transplant-ineligible patients

PD-1 antibody with or without brentuximab vedotin as ongoing therapy; palliative radiotherapy for symptomatic sites.

The options, in plain words

Nivolumab was the second PD-1 blocker and is often combined with ipilimumab. Long-term data show about half of advanced melanoma patients alive at 10 years on the combination.

The ADC that made the modern field credible (2011), for Hodgkin lymphoma and CD30+ lymphomas.

IMRT and IGRT shape the radiation beam to the tumour's outline from multiple angles and check the patient's position with a scan before every session, so surrounding organs receive less dose. Fewer, larger doses are now standard in breast and prostate cancer, but a low-dose bath still spreads across normal tissue.

  • Conformal dose, fewer side effects
  • Hypofractionation saves visits
