Late effects of treatment in lymphoma survivors

Late Effects of Treatment in Lymphoma Survivors

Why are late effects important
Why are Late Effects Important?

  • Because there are more survivors!

  • Increasing cure rates with modern therapies

  • Increasing incidence of HL/NHL as the demographic shift occurs in an ageing population

  • Increasing interest in this group:

Why are late effects important1
Why are Late Effects Important?

  • NHSI Cancer Survivorship Initiative

  • Cancer Reform Strategy 2007

  • Patient Groups-

    • Lymphoma Association

  • Other Charities-

    • British Heart Foundation

    • Cancer Research UK

  • Patients themselves


  • Are not as well as age-matched controls

  • Want more information about life after cancer

  • Need to know how to seek help and advice

  • The experience of cancer and the treatment needed will have some impact on quality of life for 25-50% of patients

  • Between 5-20% of people say this has had a major impact on their quality of life

Who gets them
Who Gets Them?

  • Long term survivors of aggressive lymphomas

  • They will have been cured with a variety of different treatments

  • All of these carry risks for the future

Background curable lymphomas
Background: Curable Lymphomas

  • Diffuse Large B-Cell NHL (~50%)

  • Hodgkin Lymphoma (50-95%)

  • Burkitt’s Lymphoma (70%)

  • Rarer aggressive sub-types (some T-cells, rarely mantle cell, <30%)

Background some numbers
Background: Some Numbers

  • NHL

    • Approx 9500 new cases of NHL/year

    • Approx 3000 are aggressive/curable

    • Therefore ~1500 long-term survivors

    • Median age ~60

  • Hodgkin Lymphoma

    • Approx 1500 cases/year

    • >1000 survivors generated

    • Median age 29

Background curative therapies
Background: Curative Therapies

  • R-CHOP:

    • Rituximab/cyclofosfamide/ doxorubicin/vincristine/ prednisolone

  • ABVD:

    • doxorubicin/bleomycin/vinblastinedacarbazine

Background curative therapies1
Background: Curative Therapies

  • Radiotherapy:

    • curative in Stage 1a disease, used as consolidation in HL, bulky disease, v.aggressive tumours

  • Stem Cell Transplantation:

    • high doses of chemo (BEAM, fludarabine), graft-versus-host disease, total body irradiation

What are the late effects
What are the Late effects?

  • Many and varied!

  • Definitions a bit controversial:

    • When is a treatment-related problem ‘late’ as opposed to ‘early’

    • Sterility/fertility is a good example

  • Most would call problems >5 years out as ‘late’


  • Psychosocial

  • Cardiac

  • Pulmonary

  • Endocrine

  • Second Cancers

  • Bone Marrow


  • Difficulty obtaining jobs, mortgages, life insurance

  • Depression

  • Fear for/of the future

  • Relationship problems


  • Anthracyclines (doxorubicin, epirubicin) known to be cardiotoxic

  • As is supradiaphragmatic radiotherapy

  • More recently, vinca alkaloids (vincristine, vinblastine) also found to be associated with cardiotoxicity

  • This has been confirmed in a recent study:


  • 7033 Hodgkin disease patients who were treated in Britain from 1967 through 2000 were studied

  • A total of 166 deaths from myocardial infarction

  • Standardized mortality ratio (SMR)= 2.5 x age-matched controls

  • Risk was particularly high for patients treated with the ABVD regimen (SMR = 9.5)

  • Swerdlow et al. J Natl Cancer Inst. 2007 Feb 7;99(3):206-14.


  • Major effect is increased risk of Ca Lung

  • Risk increased by:

    • MOPP chemo (now not used)

    • Radiotherapy to the thorax, esp. ‘Mantle Field’

    • Tobacco smoking multiplies the risk

  • Relative risk (RR) varies from 2x to 15x according to a variety of factors

  • Lancet Oncol 2005;6:773-79


  • Bleomycin (ABVD, BEACOPP, VAPEC-B) can cause pulmonary fibrosis both acutely and in the long term

  • Can lead to late onset asthma/COPD

  • Again, risk is synergistic with smoking


  • Lance Armstrong (7 times Tour De France winner) famously declined bleomycin (in BEP) when treated curatively for stage 4 testicular Ca!


  • Wide variety of hormone deficiency syndromes reported in survivors

  • RR of hypothyroidism up to 9x in patients who receive mantle/upper thoracic/neck XRT

  • Hypogonadism seen in patients treated with intensive chemo regimens, and esp. transplants


  • Manifests as reduced testosterone and libido in males

  • Oligo/amenorrhoea in females due to premature ovarian failure

  • This has secondary effects on bone density, leading to osteopaenia/porosis

Second cancers
Second Cancers

  • Increased risk in all cancer survivors

  • Most if not all cancer treatments are in themselves carcinogenic

  • Radiotherapy and alkylating chemo (cyclofosfamaide/dacarbazine etc) esp. risky

  • RR varies from 9.9x (leukaemias) to 1.6x (Ca Bowel) in a series of 32,591 HL survivors (Dores et al, 2002)

Ca breast
Ca Breast

  • Lifetime risk in untreated female population:

    • 10%

  • Lifetime risk in female population treated with supradiaphragmatic radiotherapy:

    • 14-30% according to XRT field

    • Commences ~ 10 years out from XRT

Bone marrow failure
Bone Marrow Failure

  • Treatment related myelodysplasia (tMDS) risks:

    • ~1% with chemo

    • 1.5-2% with radioimmunotherapy (Zevalintm)

    • 5-10% post autograft

  • Similar rates for Acute Myeloid Leukaemia

Follow up

  • Follow up is of course important

  • The big question is how this should be done!

Practice at the christie
Practice at The Christie

  • Val Goode set up this service in the 1990s for lymphoma patients

  • Ad-hoc service since the 1980s

  • Patients seen 3-6 monthly in years 0-5, mainly for relapse

  • Annually years 5-10

  • Bi-annually thereafter

  • Offered discharge at year 20!

What are we doing
What are we doing?

  • Focused history/exam every visit

  • FBC/biochemistry up to year 3

  • TFTs annually in those at risk of hypothyroidism

  • Chest X-rays for those with previous mediastinal bulk/thoracic XRT/pulmonary lesions

What are we doing1
What are we doing?

  • Appropriate referrals to endocrine/fertility/cardiology etc

  • Psycho-oncology

    • Informal support/advice

    • Formal referral

  • Referral for Breast Screening

Breast screening
Breast Screening

  • A national notification risk assessment and screening programme (NRASP) was set up in 2003

  • Offered to females who

    • Have received XRT to the thorax/mediastinum/breasts

    • under the age of 36 at the time

  • Commences 8 years following completion of treatment

  • Annual screening until the age of 50

  • May require USS or MRI mammography

  • Then have 3-yearly screening in the national breast screening programme

Breast screening1
Breast Screening

  • This has been looked at in a pilot study (BJC (2009) 101, 582 – 588):

  • NRASP database searched

  • 417 women invited for clinical review

  • 243 (58%) attended

  • 23 (5.5%) have been diagnosed with Ca Breast by the NRASP

  • Standardised incidence ratio of 2.9 compared with the age-matched general population

What are we not doing
What are we not doing?

  • Lots of things!

  • Clear area of unmet need for this population

  • Lots of work to do!

The future of late effects
The Future of Late Effects

  • Detect

  • Treat

  • Prevent


  • Ensure all patients are offered/ encouraged to attend follow-up for relapse initially, and later on for late effects:

    • Do we have the databases?

    • Resources:

      • Staff/space/money!


  • Picking up problems:

    • Correct tests at the right times

    • National Screening Programmes:

      • Breast- established 2003, improvements proposed

      • Lung- proposed

      • Cardiac- proposed

      • Endocrine- ad hoc?

  • Further research needed in this area:

    • Biomarkers of early disease

    • Preliminary work underway at The Christie


  • Different age/disease groups may need different approaches

  • Personalised treatment summaries may help

    • Anyone can offer follow up according to its recommendations

    • ‘Dip-in/dip-out’ may appeal to teenage or busy working adults


  • Should we be treating late effects the same as de novo diseasese.g. should XRT induced Ca Breast be treated the same as sporadic?

  • Do the various specialists need knowledge of the original oncology diagnosis/treatments?


  • Better never than late?


  • Can we minimise/eliminate some or all late effects?

  • Two main strategies to employ here:

    • De-escalate therapies based upon individualised treatment plans/biomarkers of good prognosis

    • Substitution of less-toxic therapies

Prevention some examples
Prevention: Some examples

  • RAPID Study

    • 1A/2A Hodgkin Lymphoma

    • Those who are PET –ve after chemo are randomly assigned to receive XRT or not

  • R-GCVP Study

    • Removing doxorubicin from CHOP and replacing it with gemcitabine in patients with DLBCL and poor cardiac risk


  • Late effects are under-detected and under-treated

  • Huge area of unmet need:

    • Basic research

    • Service gaps

    • Patients and families

  • There are some basic things that we can be doing now
