Aim: To investigate the utility of local resection (LR) for T1 duodenal carcinoma and T1 ampullary carcinoma.
Patients And Methods: Between June 2002 and November 2014, a total of 64 patients with pathological T1 (pT1) ampullary carcinoma (25 patients) and pT1 duodenal carcinoma (39 patients) were treated. Of these, 33 patients underwent local resection (LR group), while the other 31 patients underwent pancreatoduodenectomy (PD group).
Results: The LR group had 31 patients with pT1a and 2 patients with pT1b. PD group had 18 patients with pT1a and 13 patients with pT1b. One patient with pT1b duodenal carcinoma (20.0%) and one patient with pT1b ampullary carcinoma (10.0%) developed lymph node metastasis, while none of the patients with pT1a disease developed metastases.
Conclusion: LR may be considered in the patients preoperatively diagnosed with T1a duodenal carcinoma and T1a ampullary carcinoma.

Background: As a novel inflammatory-nutritional biomarker, the C-reactive protein-albumin-lymphocyte (CALLY) index has demonstrated significant prognostic value in various malignancies. However, research on its association with the prognosis of ampullary carcinoma (AC) is rare. This study aims to investigate the relationship between the CALLY index and the prognosis of patients with AC.

Common pancreatobiliary epithelial malignancies such as pancreatic ductal adenocarcinoma, cholangiocarcinoma and gallbladder carcinoma have poor prognosis. A small but significant portion of these malignancies arise from mass-forming grossly and radiologically visible premalignant epithelial neoplasms in the pancreatobiliary tree. Several lesions, including a few recently described entities, fall under this category and predominantly include papillary epithelial lesions with or without mucin production.

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.

Background/objective: Patient-derived organoids (PDOs) have emerged as essential for ex vivo modelling for pancreatic cancer (PDAC) but reports on efficacy and organoid take rate are scarce. This study aimed to assess the feasibility of establishing PDOs from resected specimens in periampullary tumors.
Methods: Patients undergoing surgery for suspected periampullary cancer were included.

Background And Objective: Ampullary carcinoma (AMPAC) taxonomy is based on morphology and immunohistochemistry. This classification lacks prognostic reliability and unique genetic associations. We applied an approach of integrative genomics characterising patients with AMPAC exploring molecular subtypes that may guide personalised treatments.
