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

Valencia Clinical Hospital, University of Valencia, Biomedical Research Institute, Incliva, Valencia.
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). An intraoperative liquid biopsy (ILB) based on tumor cell mobilization could help to detect R1 resection intraoperatively.
Objective: To evaluate the potential role of the intraoperative circulating tumor cells (CTCs) and cluster mobilization on the R0/R1 detection.
Giant Granular Cell Tumor of the Left Thigh, a Rare Case Report and Literature Review.

Background: Granular cell tumor (GCT) is a rare soft tissue tumor characterized by Schwann cell differentiation. While GCT can occur in any part of the body, it is less common in the lower limbs. We report a case of a giant atypical GCT located in the left thigh, the tumor was initially small and painless at the time of discovery but gradually grew to 17 cm over a two-year period.

Background: Basal cell carcinoma is the most common skin malignancy. The standard treatment is surgical excision with predetermined margins. Some argue that the currently recommended surgical margins are excessive, and it is questionable whether such wide surgical margins should be applied to all lesions.

Int J Surg Pathol
January 2025
Department of Pathology, Marmara University School of Medicine, Pendik/Istanbul, Turkey.
The presence of high tumor budding in colorectal carcinomas is a significant pathological feature indicative of a high potential for lymph node metastasis. Our aim was to investigate the prognostic impact of tumor budding in ampullary carcinomas. We conducted a cohort of 101 consecutive ampullary carcinoma resections to evaluate tumor budding, macroscopic and microscopic subtypes, lymphatic/vascular/perineural invasions, and other histopathological parameters.

Department of Surgery, The NYU Grossman School of Medicine and NYU Langone Health, New York, NY. Electronic address:
Background: To improve outcomes for patients with pancreatic ductal adenocarcinoma, a complete resection is crucial. However, evidence regarding the impact of microscopically positive surgical margins (R1) on recurrence is conflicting due to varying definitions and limited populations of patients with borderline-resectable and locally advanced pancreatic cancer. Therefore, we aimed to determine the impact of the resection margin status on recurrence and survival in patients with pancreatic ductal adenocarcinoma stratified by local tumor stage.
