NON-HODGKIN’S LYMPHOMA
(NHL)
• Approximately 1.5 million people worldwide are living with
non-Hodgkin’s
lymphoma (NHL), and it is estimated that
300,000 people die each year from the disease
• 1 new case diagnosed every 9 minutes*
• 81% increase in incidence of NHL between
1973 -1990
• NHL is the third fastest growing cancer (excluding
the US) in terms of population in the world
• NHL is leading cause of death due to cancer in
men aged 20-40 years

Rationale der
Radioimmuntherapie bei NHL
• NHL sind von Natur aus sehr strahlensensibel
• Die Radiotherapie kann bei NHL in frühen
Stadien kurativ sein
• Radioaktiv markierte Antikörper bringen die
Strahlung zielgerichtet zum Tumor
• Die Radioimmuntherapie kann sowohl Ziel- als
auch Nachbarzellen vernichten (“KreuzfeuerEffekt”) und so auch grosse oder gering
vaskularisierter Tumoren erreichen
CD20 is an Ideal Target for
Radioimmunotherapy
• CD20 antigen:
– Proven target for
lymphoma therapy
Malignant B-cell
– Expressed only
on B-lineage cells
– Does not shed into
circulation
CD20
antigen
– Does not modulate
upon antibody
