Purpose: To present data to support the hypothesis that human retinoblastoma tumors form by a multistep process. Methods: Survey of the karyotype of 90 human retinoblastomas, with emphasis on changes in chromosomal regions known to contain oncogenes and tumor suppressor genes. Conclusion: The data support the hypothesis that retinoblastoma occurs after multiple and often varied steps, similar to other human malignancies.
