The data from the American Rheumatism Association Medical Information System (ARAMIS) about the lack of azathioprine-induced neoplasia (Singh G, Fries JF, Spitz P, Williams CA: Toxic effects of azathioprine in rheumatoid arthritis: a national post-marketing perspective. Arthritis Rheum 322337443, 1989) are, I’m sure, statistically unimpeachable. However, I question their clinical significance. The duration of therapy and, I believe. followup was 20.8 (2 1.1 SEM) months. The authors of studies that have shown a risk of drug-induced neoplasia have pointed out that the increased risk may, not be seen until many years later (Baker GL, Kahl LE, Zee BC, Stoker BL, Agarwal AK, Medsger TA: Malignancy following treatment of rheumatoid arthritis with cyclophosphamide: long term case control follow up study. Am J Med 83: l-9, 1987). While the discussion following the ARAMIS results suggests that a longer followup is necessary to “provide an unequivocal answer,” I am concerned that shorter studies merely muddy the waters by adding to the list of referenced studies that have failed to demonstrate an association.
