Atlas Of Exocrine Pancreatic Tumors

The classification of tumors is important for understanding tumor histogenesis, for predicting prognosis, for differential diagnosis, and for recommending appropriate therapy. Since 1836, when pancreatic cancer was first described, progress has been made in pancreatic cancer morphology, and a number of classifications have been proposed. All of these classifications are mainly based on morphological characteristics. Some are too detailed to be of practical use while others are more pragmatic. Some of the inherent problems in the previous classifications included difficulties in obtaining an adequate number of pan creatic tumors for examination and insufficient clinical data and follow-up. With the increasing incidence of pancreatic cancer in many parts of the world during the past six decades, and with the availability of more tumors to patho logists, advances have been made in pancreatic tumor studies. Classifications by Cubilla and Fitzgerald and by Kloppel, which are generally similar, mostly considered prominent morphological features and their histogenesis. These pathology-oriented classifications, although complete, were not practical from the standpoint of clinicians concerned with the prognosis of individual tumors.

In addition to the extensive discussion, illustrations, and up-to-date referencing of the numerous pancreatic tumours and tumour-like lesions, normal gross, histologic and cytologic findings, and on pancreatic tumour staging are covered. These discussions complement the treatment of the issue of frozen section interpretation, dissection, and reporting of pancreatic resection specimens.

This book comprehensively discusses advanced surgical techniques for pancreatic cancers, including open, laparoscopic and robotic-assisted surgery, as well as palliative surgery and total meso-pancreas excision. It also features high-resolution illustrations taken from selected clinical cases to enhance the descriptions of the surgical procedures. Providing details of technical issues and commenting on the outcome, it a timely reference resource for pancreatic surgeons, pancreatic physicians, and interns interested in pancreatic cancer surgery.

Although interest in pancreatic pathology is very high in the radiological and gastroenterological communities, it is still the case that less is known about pathology of the pancreas than about liver pathology, for example. Diagnosis depends on the structure of the pancreatic lesion, which can be directly visualized on US, CT or MR images. This atlas, which encompasses both the imaging and the pathology of pancreatic neoplasms, will therefore be invaluable in enabling radiologists and sonographers to understand the underlying pathology and in allowing pancreatic pathologists to understand the imaging translation. The emphasis in the atlas is very much on the pathological and imaging appearances, with most of the text concentrated at the beginning of the chapters. A comprehensive overview is provided of typical and atypical presentations and diverse aspects of common and uncommon pancreatic neoplasms, including ductal adenocarcinoma, neuroendocrine neoplasms, intraductal papillary mucinous neoplasms, cystic neoplasms, metastases and lymphoma.
