Malignancies in rheumatoid arthritis patients treated with cyclosporin A
1Department of Clinical Research, Sandoz Pharma Ltd, Basel, Switzerland.
Abstract:
More than a thousand RA patients have been treated with cyclosporin A (CyA) in clinical trials. In seventeen of them, tumours developed after treatment with the drug. An indirect approach used to calculate the relative risk associated with the use of CyA in clinical trials suggested that: (i) RA itself increases the risk of cancer development; (ii) the use of CyA further increases the risk by approximately the same degree as DMARDs; and (iii) neither the pattern of malignancies nor the risk associated with CyA seems to be different from that observed with conventional DMARDs. Nevertheless, patients treated with CyA should be carefully monitored while more experience is gathered.
Insights
Rheumatoid arthritis patients treated with cyclosporin A (CyA) showed an increased cancer risk, similar to other DMARDs. Careful monitoring is advised for those on CyA due to potential tumor development.
Area of Science:
- Immunology
- Oncology
- Rheumatology
Background:
- Rheumatoid arthritis (RA) is associated with an increased risk of cancer.
- Cyclosporin A (CyA) is an immunosuppressive drug used in RA treatment.
- Tumor development has been observed in RA patients treated with CyA.
Purpose of the Study:
- To evaluate the relative risk of cancer associated with cyclosporin A (CyA) in rheumatoid arthritis (RA) patients.
- To compare the cancer risk of CyA with conventional disease-modifying antirheumatic drugs (DMARDs).
Main Methods:
- An indirect approach was used to calculate the relative risk of malignancy.
- Data from clinical trials involving over a thousand RA patients treated with CyA were analyzed.
Main Results:
- RA itself increases cancer development risk.
- CyA use further elevates cancer risk, comparable to DMARDs.
- The pattern of malignancies and risk associated with CyA did not differ from conventional DMARDs.
Conclusions:
- While CyA may increase cancer risk in RA patients, it appears similar to conventional DMARDs.
- Careful patient monitoring is recommended during CyA treatment.
- Further experience and data are needed to fully understand CyA's long-term oncogenic potential.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
