Abstract

The anatomic location of the pancreas can result in involvement of major vasculature, which may act as a contraindication to resection. Several classification systems have been developed. We sought to discover the variations in the HPB community determining PDAC resectability. The multiple-choice survey was distributed to all full members of the IHPBA. Questions were asked regarding demographics and clinical scenarios regarding tumor resectability. 164 responses were submitted. Most of the respondents were male and had been in practice for over 10 years. The median age range was 40–50 years old. Most practiced in either Asia (n = 57,35.9%), North America (n = 52,32.7%), or Europe (n = 32,20.1%). Classification systems used to determine resectability were: NCCN (n = 42,26.3%), JPS (n = 35,21.9%), International consensus (n = 33,20.6%), AHPBA/SSO (n = 23,14.4%), Alliance (n = 3,1.9%), and other/no-classification (n = 23,14.5%). There was significant variation in the frequency of the most common answer within the scenarios (84.7%–33.5%). Participant concordance with their stated classification system found a median rate of 62.5%. Participant decision of tumor resectability was not dependent on their adopted classification system. When classifying PDAC resectability, there is significant variation between surgeons as to how they would classify a specific tumour, independent of the classification system they use. In addition, surgeons do not show high concordance with the definitions within that classification system.
