Core Tip
Core tip: Owing to the anatomical complexity of the pancreas head cancer, it is not always easy to share the exact disease status among multidisciplinary treatment members. So, we made a preoperative defining system, which contained the important clinical variables (resectability, tumor location, vascular relationship, adjacent organ involvement, preoperative CA19-9, vascular anomaly) to decide the treatment plan for pancreas head cancer. Through internal validation, we proved that this system could be useful not only to clarify the disease characteristics but also to predict oncologic outcomes of pancreas head cancer.
