Colorectal Cancer Liver Metastases: Is an R1 Hepatic Resection Accepted?

Clinics and Practice, 2022
Metastatic colorectal cancer is associated with a rather dismal 5-year overall survival. The liver is the most commonly affected organ. Improved 5-year survival rates after successful hepatic resections for metastases confined to the liver have been ...

Recurrence at surgical margin following hepatectomy for colorectal liver metastases is not associated with R1 resection and does not impact survival. [PDF]

Surgery, 2020
BACKGROUND Resection margin status has traditionally been associated with tumor recurrence and oncological outcome following liver resection for colorectal liver metastases. Previous studies, however, did not address the impact of resection margin on the

Impact of positive microscopic resection margins (R1) after gastrectomy in diffuse-type gastric cancer

Journal of Cancer Research and Clinical Oncology, 2023
Diffuse-type gastric cancer (DTGC) is associated with poor outcome. Surgical resection margin status (R) is an important prognostic factor, but its exact impact on DTGC patients remains unknown. The aim of this study was to assess the prognostic value of

The mesopancreas is the primary site for R1 resection in pancreatic head cancer: relevance for clinical trials [PDF]

Langenbeck's archives of surgery (Print), 2009
PurposeThe prognosis of patients with pancreatic cancer remains poor, even after potentially curative R0 resection. This discrepancy may be due to the histopathological misclassification of R1 cases as curative resections (R0) in the past.Materials and ...

R1 Vascular or Parenchymal Margins: What Is the Impact after Resection of Intrahepatic Cholangiocarcinoma?

Cancers, 2022
Simple Summary The long-term outcome of R1 vascular (R1vasc) and R1 parenchymal (R1par) resections in the setting of intrahepatic cholangiocarcinoma (iCCA) is not well studied.

Intraoperative liquid biopsy as a tool for detecting R1 resection during pancreatoduodenectomy in patients with pancreatic carcinoma: the CETUPANC trial (part II). [PDF]

Int J Surg
Introduction: A positive surgical margin (R1 resection) is a relevant risk factor for local recurrence in patients with pancreatic ductal adenocarcinoma of the pancreas (PDAC).

A systematic review of margin status in retroperitoneal liposarcomas: Does the R0 margin matter?

Frontiers in Oncology, 2022
Retroperitoneal liposarcomas (RPLPSs) are a rare tumor group for which current guidelines recommend aggressive en bloc resection to attain microscopically negative (R0) margins.

Can the surgeon prolong the remaining life of the patient in pancreaticoduodenectomy surgery? or Is the surgeon helpless?

Cirugía y Cirujanos, 2022
Background: We aimed to evaluate the effects of R0 and R1 resections after pancreatic surgery. Methods: Data of 130 patients were evaluated. Re-resection was performed in patients who were found to have R1 resection after frozen section (FS).

The Impact of Intraoperative Frozen Section on Resection Margin Status and Survival of Patients Underwent Pancreatoduodenectomy for Distal Cholangiocarcinoma

Frontiers in Oncology, 2021
BackgroundIntraoperative frozen section (FS) is broadly used during pancreaticoduodenectomy (PD) to ensure a negative margin status, but its survival benefits on obtaining a secondary R0 resection for distal cholangiocarcinoma (dCCA) is controversial and

Severe Postoperative Complications Adversely Affect Long-Term Survival After R1 Resection for Pancreatic Head Adenocarcinoma

World Journal of Surgery, 2013
BACKGROUND: Survival after pancreatic head adenocarcinoma surgery is determined by tumor characteristics, resection margins, and adjuvant chemotherapy. Few studies have analyzed the long-term impact of postoperative morbidity.
