Eighty surgeons from county-level hospitals were recruited and randomly assigned to two groups for a comparative study: one experiencing CBL alone and the other receiving CBL combined with the PDCA cycle.<\/jats:p>\n <\/jats:sec>\n \n Methods:<\/jats:title>\n \n Participants in both groups underwent a 5-day breast cancer therapeutic strategy course. The effectiveness of these methodologies was assessed using pretraining and post-training tests, examinations, and a satisfaction questionnaire. Statistical analysis was conducted to compare the knowledge gains between the two groups using pretraining and post-training assessment scores, with the significance level set at\n P<\/jats:italic>\n < 0.05.\n <\/jats:p>\n <\/jats:sec>\n \n Results:<\/jats:title>\n \n Both instructional methods resulted in knowledge improvement, but the group that received CBL with PDCA demonstrated significantly
