ChatGPT recommendations align with tumor board in 85% of surgical oncology cases but diverge on resectability

Retrospective study of 47 general surgery patients: ChatGPT-based AI recommendations had 85% at least partial concordance with tumor board decisions, but discorded in 15%, especially on resectability and staging, tending to favor broader surgery.

• Retrospective observational study of 47 patients discussed at a single multidisciplinary tumor board for oncologic surgery.
• Discordance was more frequent in males (26.3% vs. 7.1% female) and most often due to resectability and staging interpretation differences.
• Small, single-institution sample without external validation; AI was a general-purpose chatbot, not a specialized medical AI.
