This study elucidated these aspects among Certified Nurse Specialists (CNSs) and Certified Nurses (CNs) in Japan.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>A web\u2010based survey was administered to 1490 nurses, including CNSs in cancer nursing and CNs in cancer chemotherapy, breast cancer, and heart failure. The survey assessed participants' characteristics, knowledge of CTRCD, nursing practices, consultation experiences, and interprofessional collaboration. We calculated descriptive statistics and conducted group comparisons between oncology nurses specializing in cancer nursing and cardiology nurses specializing in heart failure nursing.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      We obtained 261 responses, including 214 (82.0%) from oncology nurses and 47 (18.0%) from cardiology nurses. These two groups exhibited significant differences in their knowledge of CTRCD definitions, risk factors, and related agents (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.01). Among oncology nurses, 88 (56.8%) provided patient education on CTRCD risk and 94 (63.9%) monitored CTRCD symptoms; thus, practice implementation remained around half. A higher proportion of cardiology nurses reported having received questions or consultations regarding CTRCD from patients or staff (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009&lt;\u20090.05).
