RT Journal Article SR Electronic T1 The spectrum of histopathological changes encountered in pancreatectomy specimens after neoadjuvant chemoradiation, including subtle and less-well-recognised changes JF Journal of Clinical Pathology JO J Clin Pathol FD BMJ Publishing Group Ltd and Association of Clinical Pathologists SP 463 OP 471 DO 10.1136/jclinpath-2016-203604 VO 69 IS 6 A1 Kalimuthu, Sangeetha N A1 Serra, Stefano A1 Dhani, Neesha A1 Chetty, Runjan YR 2016 UL http://jcp.bmj.com/content/69/6/463.abstract AB Preoperative (neoadjuvant) chemoradiation therapy/treatment (NCRT) is emerging as an important treatment modality in borderline resectable pancreatic ductal adenocarcinoma (PDAC). The constellation of histopathological changes secondary to chemoradiation is diverse and has been well documented, particularly in other gastrointestinal organs such as the oesophagus and colorectum. However, the histological changes specific to the pancreas have not been fully characterised and described. This review aims to provide a detailed catalogue of histological features associated with NCRT-treated PDAC and highlight any subtle, less-recognised changes.
