Issues in Haematological Malignancy 2010Prof. A H Goldstone CBE
AML • ALL • CML • CLL • Myeloma • Lymphoma
There is more that can be achieved almost everywhere and the PCTs and Insurance Companies are running scared
AML – Acute Myeloid Leukaemia • The elderly still do badly • Targeted therapy anti CD33 (Mylotarg) • RIC transplant for the older patient - (50-65)
ALL – Acute Lymphoblastic Leukaemia • Adults still do badly • Kids 90% survival • Adults 35% survival • Antibody treatment arrives • Rituximab may also be useful in ALL • More transplant!- • Unrelated donors transplant increasing • RIC (reduced intensity conditioning)
CML – Chronic Myeloid Leukaemia • Arrival of tyrosine kinase inhibitors (TKIs) • Imatinib (Glivec) “wonder drug” now produces 90% 10 year survival • Probably needs to be continued indefinitely £25K/yr • Very few patients now need transplanting
CLL – Chronic Lymphocyte Leukaemia • Strategy moves from “suppression” to induction of remission • FCR (Fludarabine, Cyclophosphamide, Rituximab) • More complex treatment, more immunosuppression, more commitment of patient • Younger patients should be considered for transplant – this disease is sometime CURABLE!
Myeloma • Drugs begin to be effective • Thalidomide • Bortezomib (Velcade) • Lenalidomide (Revlimid) • Side effects are considerable and need close monitoring • Outlook now increased from 2-3 yrs to 6-8 yrs • Every patient of whatever age worthy of consideration of first line therapy
Lymphoma is:- • The most common blood cancer, more common than leukaemia and myeloma • Most common cause of blood cancer death • 5th leading cause of cancer death in men, 4th in women • Causes 11% of childhood cancers • Increasing 4%/year
Age-specific incidence rate (case numbers per 100,000 per year) for cases of NHL collected from geographically defined areas of the UK 1984-1993
Lymphoma – A growing problem Increasing incidence of NHL Non-Hodgkin's Lymphoma Hodgkin's Lymphoma Australian Institute of Health and Welfare 2000
The following table gives the estimated numbers of new cases and deaths for each common cancer type:
Approximately 1.5 million people worldwide are living with non-Hodgkin’s lymphoma (NHL) • It is estimated that 300,000 people die each year from the disease
Facts and Figures • 1 new case of lymphoma is diagnosed every 9 minutes* • 1 in 50 people will develop lymphoma* • 81% increase in incidence of NHL between 1973-1990 • Overall survival at 5 years is 50%-60% for all non-Hodgkin’s lymphomas • *US statistics • Ries LAG, et al. SEER Cancer Statistics Review, 1975-2000, National Cancer Institute. Bethesda, MD • Cancer Facts & Figures 2004, www.cancer.org
Lymphoma: Current Challenges Müller A et al. Ann Hematol. 2005;84:1-12; Hagemeister FB. New agents in the treatment of lymphomas: which ones will succeed. Available at: www.cmeinteractive.cancerconsultants.com/ShowArticle.aspx?ArticleID=2. • Continued increase in incidence 3-4% increase in annual incidence of NHL over last 2-3 decades • Diverse disease made up of numerous subtypes. Careful patient selection necessary to maximize treatment benefit • Despite improvements in outcomes over the past decade, some subgroups of NHL, in particular, remain difficult to treat • Development of newer treatment strategies critical to improving outcomes
Non-Hodgkin Lymphoma: Incidence Other subtypes with a frequency ≤ 2% (9%) Peripheral T-cell (6%) Follicular lymphoma (22%) Mantle cell (6%) Small lymphocytic lymphoma (6%) Composite lymphomas (13%) Marginal zone B-cell lymphoma MALT type (5%) Marginal zone B-cell lymphoma nodal type (1%) Diffuse B-cell lymphoma (31%) Lymphoplasmacytic lymphoma (1%) Armitage et al. J Clin Oncol. 1998;16:2780-2795.
Low Public Awareness of Lymphoma According to a study of lymphoma patients carried out in 2003: • Prior to diagnosis almost all respondents (97.5%) had been unaware of non-Hodgkin’s lymphoma • Many patients with non-Hodgkin’s lymphoma do not have an accurate understanding of the disease • Up to 35% of respondents were vague about the body parts affected by non-Hodgkin’s lymphoma • Half of respondents were unaware of their specific diagnosis
Cause-specific Survival of NHL Study Patients (1974–1995) 100 80 60 40 20 0 Cumulative survival (%) Aggressive NHL Indolent NHL 0 5 10 15 20 25 30 Time (years)
Other reasons for incidence of NHL • Many are age-related • Auto-immune disease • Environmental chemicals
Lymphomas associated with host susceptibility factors • Enteropathy – associated T-cell Lymphoma - Genetics - Gliadin allergy • Extranodal and systemic EBV + T/Non-Hodgkin’s Lymphoma - Genetics • Hepatosplenic T-cell Lymphoma - Immunosuppression + chronic autogenic stimulation • Burkitt - Malaria + HIV • Post transplant Lymphoma - Iatrogenic immunosuppression
HIV – associated Lymphomas • DLBC • Primary CNS Lymphoma • Burkitt • Primary Effusion Lymphoma • 600 fold increase for immunoblastic Lymphoma • 14 fold xs for low grade Non-Hodgkin’s Lymphoma • Hodgkin’s Lymphoma
Lymphoma associated with Infectious Agents • Nasal, cutaneous NK/T EBV • Adult T-cell leukaemia Lymphoma HTLV1 • Marginal zone H.pylori, campylobacter, Hepatitis C • Primary effusion Lymphoma HHV-8/KSHV
A Cancer in Disguise • Symptoms are commonly seen in other, less serious illnesses, such as influenza or other viral infections and are often overlooked • Symptoms can appear anywhere in the body
Diagnosis of NHL • Physical examination • Chest X-ray • Ultrasound • CT scan & PET Scan • Bone marrow biopsy • Blood test, incl. cell surface marker phenotype Sometimes: • Cytogenetics • Gene rearrangement • Liver biopsy • MRI
CAUTION • Is the rise apparent and not real? • Are we just better at finding and diagnosing?
New diagnostic and therapeutic areas in Lymphoma • PET scanning - diagnosis - activity - prognosis • Immunohistochemistry • Targeted therapies - eg Rituximab • Stem cell transplantation
The Rationale for Transplant in Lymphoma Auto • Dose Conventional Allo • DOSE • ALLO EFFECT Mini-Allo • DOSE • ALLO EFFECT
PET+ve after 2# ABVD predictive of treatment failure in HL PET-2-ve: 2yr FFS 96% (n=161) PET-2+ve: 2yr FFS 14% (n=41) Gallamini et al, ASH 2006 (n=202)
Hodgkin Lymphoma • Normally 5 x less frequent than NHL • More frequent also in HIV patients • Now 2 subtypes - Classical - NLPH (nodular lymphocytic predominant)
Radiotherapy in Hodgkin’s • Much less frequently used today • Major problem with Breast Cancer after “Mantle” field • Chemo more toxic short term but less toxic long term • Fertility issues with new escalated chemo • Issues of “Survivorship”
Why Targeted Therapies? • Need to improve outcomes for all types of lymphoma -Improve cure rate for aggressive lymphomas -Maintain remission for indolent disease -Eradicate minimal residual disease -Decrease relapse rate for all lymphoma • Lymphoma frequently associated with deregulated cellular pathways of differentiation, proliferation or survival -Molecules involved in these aberrations provide rational targets for selective therapies • Agents generally well tolerated and easily combined with other therapies (eg, chemotherapy, radiotherapy) Coiffier B.

Targeting the Cell Surface slg CD19 CD20 CD22 DR B Lymphocyte
Major Themes • Effectiveness without toxicity. • Dose escalation • Exploitation of passive & active immunotherapy
The ongoing management of the patient with active disease is vital • Lymphoma, Myeloma + CLL are of major importance in this regard • “Living with Cancer” has truly arrived in many haematological malignancies
