Recall skin-test antigens and the prognosis of stage I melanoma.
Thirty-one patients with Stage I melanoma were studied with regard to their response to common skin antigens. Patients were divided into two groups, those who had surgery alone, and those who had surgery and BCG. The results were comparable. It was found that the disease-free interval was longer and the recurrence rate lower in patients who demonstrated cutaneous hypersensitivity to common antigens than in those who did not. Patients who had Clark's levels I and II lesions were more likely to be immunocompetent. The addition of BCG in the study did not appear to decrease the rate of recurrence, which seems to be related to the basic immunological status of the individual.
