A Review of Reports of Lymphoma Occurring in Patients With Rheumatoid Arthritis or Crohn's Disease in Centocor-Sponsored and Centocor-Supported Disease Registries

This is an observational (review of records), retrospective (research activity that is
performed after the events under the study have occurred), registry study where data was
collected from 3 different registries sponsored or supported by Centocor. A registry is
data collection in a real life physician-patient setting. Physicians prescribe medications
for rheumatoid arthritis and/or Crohns disease in accordance with their usual clinical
practice and then record this information and provide it to Centocor. For this registry
study, Centocor collected data from 3 registries to evaluate the risk of getting lymphoma if
you have rheumatoid arthritis and/or Crohns disease and you have taken infliximab. Patients
that were in one of the 3 registries and had rheumatoid arthritis and/or Crohns disease and
did NOT take infliximab were also evaluated. This registry study does not involve the use of
any investigational drugs, and the protocol does not mandate the treatment regimen the
patients will receive.
