A surgical and pathological based classification of resective treatment of pancreatic cancer. Summary of an International Workshop on surgical procedures in pancreatic cancer.

BACKGROUND: The extent of pancreatic resection and lymphadenectomy, both for Kausch-Whipple pancreatoduodenectomy and for left pancreatectomy, is variable between surgeons, according to their training. METHODS: On May 30, 1998, a consensus conference on the surgical treatment of pancreatic cancer took place in Castelfranco Veneto, Italy. A group of 29 European surgeons and pathologists, recognized as international experts, analyzed the surgical and pathological procedures used in European countries to resect pancreatic cancer and examine the specimen. RESULTS: A general agreement was reached on the definitions of standard , 'radical and 'extended radical Kausch-Whipple pancreatoduodenectomy for carcinoma of the head of the pancreas, and standard and 'radical left pancreatectomy for carcinoma of the body and tail of the pancreas. Segmental venous resection, as well as adjacent organ resection, can be performed at the time of standard, radical or extended radical pancreatoduodenectomy or left pancreatectomy if required. The pylorus-preserving procedure is contraindicated only for carcinomas of the anteriorsuperior part of the head of the pancreas. Guidelines for a standardized pathological examination of the resected specimen were produced. CONCLUSION: Adoption of the recommended terminology will improve outcome comparisons between institutions performing the different procedures. Moreover, standardization of operations, terminology and pathological reporting is essential for prospective randomized trials comparing different operations either alone or within the context of adjuvant therapy studies.
