In the case of an R1 situation in the region of the CRM, an extended re-resection is not simply possible on account of the anatomical conditions with corresponding limitations by the aorta and the spinal column, in contrast to extensions of the re-resection orally or aborally.Immediate online access to all issues from 2019. Microscopic tumor involvement at the surgical resection margin (R1) is one of the most important prognostic factors for pancreas cancer.

A nationwide study re‐evaluating the data of the Finnish Cancer RegistryPrognostic factors for survival after pancreaticoduodenectomy for patients with carcinoma of the pancreatic head regionSix hundred fifty consecutive pancreaticoduodenectomies in the 1990s: pathology, complications, and outcomesCurative resection is the single most important factor determining outcome in patients with pancreatic adenocarcinomaInfluence of resection margins on survival for patients with pancreatic cancer treated by adjuvant chemoradiation and/or chemotherapy in the ESPAC‐1 randomized controlled trialR0 resection for ductal pancreatic cancer – Japanese experienceResection margins in carcinoma of the head of the pancreas. The resection is an attempt to remove a cancer tumor so that no portion of the malignant growth extends past the edges or margin of the removed tumor and surrounding tissue. 3-7 However, the rates of microscopic margin involvement (R1) reported in the literature vary markedly, from as low as 16% to >75%, and correlation with clinical outcome is observed in some, but not all studies. According to the International Union Against Cancer (UICC) classification, it is defined as ‘presence of residual tumour after treatment’.Based on these considerations, the currently used R1 definition needs to be revised for the reporting of pancreatic ductal adenocarcinoma, and a clearance >1 mm may be found more appropriate. 2012 Sep;152(3 Suppl 1):S103-11. Similar developments in pancreatic cancer have not yet been commenced, and a first important step would be the rigorous implementation of a fully standardized, detailed examination protocol.
The margins of the resected specimen are reviewed by the pathologists and should ideally be free of disease.

If slicing is performed in the same plane throughout the entire pancreatic head, problems may arise when reaching the ampulla and duodenal wall.In recent years, a novel dissection technique has been increasingly used in European and UK pancreatic cancer centres. In rectal cancer, involvement of the mesorectal CRM by the presence of lymph node metastasis within 1 mm of that margin proved to be associated with an increased risk of local recurrence. The aim of this study was to confirm the prognostic significance of R1 in colon cancer resection and to establish whether the introduction of laparoscopic colorectal surgery influenced this.Prospectively collected data on a patient pathway data manager for sequential patients with colon cancer treated at our specialist unit from January 2005 to December 2010 were analysed. Indeed, the wide range of relative incidences that have been reported for pancreatic, ampullary and distal bile duct cancer in PDE seriesAs discussed above, a universally accepted definition of microscopic tumour involvement that is predicated on the identification of the minimum tumour clearance specific for pancreatobiliary‐type adenocarcinoma is a prerequisite for uniform reporting.

A resection margin or surgical margin is the margin of apparently non-tumorous tissue around a tumor that has been surgically removed, called "resected", in surgical oncology. According to the German S3 guideline, radiochemotherapy should be performed in a postoperatively proven R1 situation, which cannot be converted by a curative extended re-resection into an R0 situation or in unfavorable conditions for an extended re-resection, independent of neoadjuvant therapy.
