The exact risk of second cancer (S.C.) following treatment of testicular seminoma is not well determined in most series. At our institution, 122 patients with pure seminoma were treated by orchidectomy followed by radiation therapy from 1951 to 1986. Six were lost to follow-up. For the 116 remaining patients, the overall 5-, 10-, 15- and 20-year survival probability was 95%, 90%, 87%, and 84%, respectively. Eleven patients developed 12 second cancers, with a cumulative risk of 7%, 16%, and 16% at 10, 15, and 20 years, respectively. Overall, the risk of second cancer was increased (O/E = 1.97, p = 0.023). There were 3 controlateral seminoma (O/E = 50, p = 0.001), 2 transitional carcinoma of the bladder (O/E = 6.9, p = 0.035), 2 non-Hodgkin's lymphoma (N.S.), 1 acute myeloblastic leukemia, 1 chronic lymphocytic leukemia, 1 intracranial dysgerminoma, 1 rectal and 1 lung adenocarcinoma. Four tumors developed within the previously irradiated field (O/E = 2.2, N.S.). Excluding second seminoma, the overall risk of second cancer was not significant (O/E = 1.33). Five of the 11 patients with second cancer are currently alive without recurrent cancer. We conclude that patients treated for seminoma have an increased risk of second cancer but the overall prognosis remains excellent. The potential factors responsible for second cancer, including irradiation, are discussed.

Immunosuppressive drugs have been used during the last 30 years in treatment of patients with severe rheumatoid arthritis. The drugs commonly used are cyclophosphamide and chlorambucil (alkylating agents), azathioprine (purine analogue), and methotrexate (folic acid analogue). There is evidence that all four immunosuppressive drugs can reduce synovitis, but disease activity almost always recurs after therapy is stopped. Since adverse reactions are frequent, less than 50 percent of patients are able to continue a particular drug for more than one year. Since it takes three to 12 months to achieve maximal effects, those patients who are unable to continue the drug receive little benefit from it. Patients treated with alkylating agents have an increased risk of development of acute nonlymphocytic leukemia, and both alkylating agents and azathioprine are associated with the development of non-Hodgkin's lymphoma. Cyclophosphamide therapy increases the risk of carcinoma of the bladder. There have been several long-term studies of patients with rheumatoid arthritis treated with azathioprine and cyclophosphamide and the incidence of most of the common cancers is not increased. Data on the possible increased risk of malignancy in rheumatoid arthritis are still being collected, and until further information is available, the use of immunosuppressive drugs, particularly alkylating agents, in the treatment of rheumatoid arthritis should be reserved for patients with severe progressive disease or life-threatening complications.
