The purpose of this study was to clarify the current status of oncology certified nurse specialist（OCNS） involvement in cancer genome medicine. A survey of 235 OCNSs who consented to participate in the study revealed that those involved in cancer genome medicine had a better understanding of hereditary tumors. Through descriptive content analysis, 8 learning needs were identified in relation to cancer genome medicine. Among these needs,［ basic knowledge of hereditary tumors and cancer genome medicine］, ［regular acquisition of up-to-date information on genetic medicine］, and［ genetic counseling in actual clinical settings］revealed no differences between OCNSs involved and not involved in genetic medicine. On the other hand,［ role of an OCNS in genetic medicine］, ［nursing care for patients and families with hereditary diseases］, ［systems and collaboration to incorporate genetic medicine into organizations］, ［information on genetic medicine for facilities other than urban/designated hospitals］, and［ programmed learning as a systematic approach to genetic medicine provided by academic societies］ differed between the groups in terms of descriptive contents
