How common is HL?
•<1% of all cancers
•~ 2000 cases in UK per year
•males > females
•peak incidence in 20 – 24 year olds
•50% of cases diagnosed in >45 year olds
•second peak in elderly people (70-79 years)
![Page 3: Management of Hodgkin Lymphoma€¦ · J et al. German HD18 study - Early interim PET Borchmann P. et al: Abstract no 0737 Advanced stage Hodgkin lymphoma PET2 +ve (DS3-5) PET2 –ve](https://reader034.fdocuments.in/reader034/viewer/2022042210/5eae57d57b20cb0d2454c820/html5/thumbnails/3.jpg)
What are the symptoms?
• Usually present with painless, enlarged lymph node
– Neck lump most common
• May have cough, shortness of breath
• Spreads from one nodal group to immediately adjacent nodes
• Later, may spread to liver, lungs, bone marrow
• May have B symptoms
– weight loss
– night sweats
– fever

How is the diagnosis made?
Biopsy of tissue, usually LN; core or excision
Reed Sternberg cell
![Page 5: Management of Hodgkin Lymphoma€¦ · J et al. German HD18 study - Early interim PET Borchmann P. et al: Abstract no 0737 Advanced stage Hodgkin lymphoma PET2 +ve (DS3-5) PET2 –ve](https://reader034.fdocuments.in/reader034/viewer/2022042210/5eae57d57b20cb0d2454c820/html5/thumbnails/5.jpg)
What tests may be required?
• Blood tests – Full blood count - ? anaemia; white cell count– ESR– Kidney & liver function (including albumin)
• Imaging– CT scan of neck, chest, abdomen, pelvis– PET/CT scan
• Bone marrow (rarely done)• Pulmonary function tests• Echocardiogram• Assisted conception unit referral

How do we stage the disease? Ann-Arbor Classification system
Stage I: single lymph node group
Stage II: more than one lymph node group SAME side of the diaphragm
Stage III: lymph node groups BOTH sides of the diaphragm (includes spleen)
Stage IV: Extranodal involvement e.g. liver, bone marrow
Itch (pruritis) is not a B symptom. Can occur in NHL and HLAlcohol induced pain is a rare feature of HL
A or B added after to signify absence or presence of B symptoms
![Page 10: Management of Hodgkin Lymphoma€¦ · J et al. German HD18 study - Early interim PET Borchmann P. et al: Abstract no 0737 Advanced stage Hodgkin lymphoma PET2 +ve (DS3-5) PET2 –ve](https://reader034.fdocuments.in/reader034/viewer/2022042210/5eae57d57b20cb0d2454c820/html5/thumbnails/10.jpg)
How do we determine the prognosis?
• staging results– extent of disease
– presence or absence of B symptoms
• prognostic scores– early stage
• EORTC score
• GHSG score
• advanced stage– Hasenclever score
![Page 11: Management of Hodgkin Lymphoma€¦ · J et al. German HD18 study - Early interim PET Borchmann P. et al: Abstract no 0737 Advanced stage Hodgkin lymphoma PET2 +ve (DS3-5) PET2 –ve](https://reader034.fdocuments.in/reader034/viewer/2022042210/5eae57d57b20cb0d2454c820/html5/thumbnails/11.jpg)
Prognostic scores – early stage
EORTC
• >/= 4 nodal areas
• age >/= 50 yrs
• mediastinal mass > 1/3 max transverse thoracic diameter
• ESR >/= 30 + B symptoms
• ESR >/= 50; no B symptoms
GHSG
• >/= 3 nodal areas
• extra nodal disease
• mediastinal mass > 1/3 max transverse thoracic diameter
• ESR >/= 30 + B symptoms
• ESR >/= 50; no B symptoms
![Page 12: Management of Hodgkin Lymphoma€¦ · J et al. German HD18 study - Early interim PET Borchmann P. et al: Abstract no 0737 Advanced stage Hodgkin lymphoma PET2 +ve (DS3-5) PET2 –ve](https://reader034.fdocuments.in/reader034/viewer/2022042210/5eae57d57b20cb0d2454c820/html5/thumbnails/12.jpg)
Prognostic score – advanced stageHasenclever score
Risk factors
• albumin < 40
• Hb < 105
• male
• stage IV
• age >/= 45
• WCC >/= 15
• Lymphocyte count < 0.6
Risk factors and 5yr OS
• 0 89%
• 1 90%
• 2 81%
• 3 78%
• 4 61%
• >/=5 56%

How do we treat HL?
• Very effective
• High cure rates (>90% in early stage;
75- 85% in advanced stages)
• Early stage combined modality Rx -chemotherapy followed by radiotherapy
• Advanced stage chemotherapy
• Late effects important eg malignancy, cardiac, pulmonary, fertility, endocrine
![Page 14: Management of Hodgkin Lymphoma€¦ · J et al. German HD18 study - Early interim PET Borchmann P. et al: Abstract no 0737 Advanced stage Hodgkin lymphoma PET2 +ve (DS3-5) PET2 –ve](https://reader034.fdocuments.in/reader034/viewer/2022042210/5eae57d57b20cb0d2454c820/html5/thumbnails/14.jpg)
ABVD
• A=adriamycin(doxorubicin)
• B=bleomycin
• V=vinblastine
• D=dacarbazine
• Given on days 1 and 15 of 28 day cycle
• most common regimen
• well tolerated
• neutropenia but infection uncommon
• bleomycin pneumonitis
• cardiac toxicity
• alopecia variable
• fertility usually spared
![Page 15: Management of Hodgkin Lymphoma€¦ · J et al. German HD18 study - Early interim PET Borchmann P. et al: Abstract no 0737 Advanced stage Hodgkin lymphoma PET2 +ve (DS3-5) PET2 –ve](https://reader034.fdocuments.in/reader034/viewer/2022042210/5eae57d57b20cb0d2454c820/html5/thumbnails/15.jpg)
What are the treatment options?
Early stage
EORTC or GHSG score
• low risk – no adverse features ABVD x 2 + RT
• high risk – ABVD x3-4 + RT or ABVD x6
• RAPID study approach
Advanced stage
• ABVD x 6
• ABVD x 6 (RATHL approach)
• A+AVD
• Escalated BEACOPP
• Escalated BEACOPDAC

Trials for early stage patients
![Page 17: Management of Hodgkin Lymphoma€¦ · J et al. German HD18 study - Early interim PET Borchmann P. et al: Abstract no 0737 Advanced stage Hodgkin lymphoma PET2 +ve (DS3-5) PET2 –ve](https://reader034.fdocuments.in/reader034/viewer/2022042210/5eae57d57b20cb0d2454c820/html5/thumbnails/17.jpg)
RAPID study
• patients who were PET negative after 3 cycles of ABVD
were randomized between no further treatment and
radiotherapy
• 3-year progression-free survival rate was 97.1% in the radiotherapy group and 90.8% in the group with no further therapy
• Modest improvement in the 3-year PFS rate (6.3%) can be obtained with the addition of radiotherapy
• Avoidance of RT may reduce incidence of second cancers and cardiac disease

Current treatment of early stage patients at the Beatson
• 2-4 cycles of ABVD depending on risk factors
followed by radiotherapy
• Discuss RAPID trial on an individual basis, especially young females

RATHL study
• Using PET scan after 2 cycles to determine treatment
• Is it safe to omit bleomycin in those that are PET negative?
• Does escalation of therapy to BEACOPP improve outcome in those who are PET +ve?

Echelon 1 study summary
• phase III study, untreated HL, stage III-IV
• ABVD v A(brentuximab)+AVD x 6
• 2 yr modified PFS: 77.2% vs 82.1%
• A+AVD – superior efficacy (4.9% improvement in modified PFS)
• Peripheral neuropathy more common with A+AVD (67% vs43%)
• Serious pulmonary toxicity more common with ABVD (3% vs1%)
• OS data yet to mature
• Is it really good enough to be the new “standard of care”?

HD18 study
• 4 cycles of eBEACOPP is as effective as 6 or 8 if PET negative after 2 cycles
• 3 yr PFS 95% vs 91%
• 3yr OS 98.8% vs 95.7%
Should we use eBEACOPP for higher risk patients?
BEACOPDac may have less side effects

Current treatment of advanced stage patients at Beatson
• majority managed by RATHL approach ieABVD x 6 with omission of bleomycin if PET scan negative after 2 cycles
• Consider escBEACOPDac if high prognostic score, especially in males
![Page 31: Management of Hodgkin Lymphoma€¦ · J et al. German HD18 study - Early interim PET Borchmann P. et al: Abstract no 0737 Advanced stage Hodgkin lymphoma PET2 +ve (DS3-5) PET2 –ve](https://reader034.fdocuments.in/reader034/viewer/2022042210/5eae57d57b20cb0d2454c820/html5/thumbnails/31.jpg)
How do we treat older or frail patients?
• ABVD - difficult to deliver
• VEPEM-B
• ChlVPP
• newer agents?

BREVITY study
• Tolerable therapy but high incidence of low-grade toxicity and dose reductions – Peripheral neuropathy an issue
• High overall response rates but mainly partial response– CMR and PFS unsatisfactory
• Need to combine with other agents

Management of relapsed HL
• Usually salvage therapy + ASCT
• Aim is to achieve PET negativity prior to transplant – outlook same whether require 1 or 2 salvage therapies
• If PET negativity not achieved, consider allo
• For minority of patients whose disease remains localised at relapse, chemotherapy + RT may be an option

Check Point Inhibitors
• Harness power of immune system to combat cancer
• Hodgkin’s RS cells express high levels of PD-L1 selective blockade of anti tumor immune response
• monoclonal antibodies directed against the receptors or ligands can be used to augment the immune response

Check point inhibitors
• Responses seen in ASCT and BV failures• Nivolumab: SMC approval as monotherapy in adults with
relapsed/refractory HL after ASCT and Brentuximab• Pembrolizumab: as above + unsuitable for ASCT• Side effects mainly immune related
– Pneumonitis – usually early– Colitis – often late
• Trials– Relapsed setting– ? In combination with BV – ?Front line

Late effects to avoid as cures increase
• Secondary MDS/AML from alkylating agents
• Solid tumours from extended field radiation
• Pulmonary fibrosis from bleomycin
• Ischaemic heart disease from mediastinal
irradiation and doxorubicin
• Infertility from alkylating agents and pelvic RT

Ovarian function sub-study of RATHL
• Premenopausal women entering RATHL
• Recording of:
– Menstrual function, fertility
– Serum markers of ovarian function (LH, FSH, estradiol) in local labs.
– AMH pre-treatment, during and following treatment
– Comparison between treatment arms

Anti-Mullerian Hormone is produced by small growing follicles
Oestradiol / FSHAMH
Anderson RA 2012 Clin Endocrinol 77, 652
This reflects the number of primordial follicles, the ‘Ovarian Reserve’, which determines reproductive lifespan

Conclusions
• BEACOPP regimens are significantly more toxic to ovarian
function than ABVD, an effect which worsens with age
• There is no detectable evidence of lasting ovarian damage by
ABVD in patients under 35
• Reduction in AMH levels appears to be permanent following
BEACOPP, although a minority of women will recover normal
gonadotrophin levels
