Background: Trials on neoadjuvant immunotherapy in operable colon cancer with deficient mismatch repair (dMMR) reported high pathological response rates in the surgical specimen, but long-term survival is not known. Neoadjuvant immunotherapy as a stand-alone therapy without subsequent radical surgery is currently not investigated in colon cancer.
Objective: The aim of this study was to model outcomes between trial data and real-world patients after surgery.
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: The use of minimally invasive (laparoscopic and robotic) pancreatoduodenectomy (PD) is being increasingly adopted despite the lack of hard evidence to support its utilisation. With recent randomised controlled trials (RCTs) comparing open pancreatoduodenectomy (OPD) with robotic or laparoscopic pancreatoduodenectomy (RPD or LPD), we undertook a network meta-analysis (NMA) comparing all 3 approaches to evaluate comparative outcomes.
Methods: A systematic search of MEDLINE, EMBASE, and Cochrane CENTRAL was conducted up to May 2024 and relevant RCTs were identified.
Background: Treatment of colorectal cancer liver metastasis (CRLM) includes several options with impact on the patient journey and may depend on presentation and patient characteristics. The aim of the study was to investigate how treatment sequencing in index hepatectomy for synchronous or metachronous CRLM may potentially impact treatment pathways and oncological outcomes.
Methods: An observational cohort study (ACROBATICC; NCT0176813) of patients having surgery for CRLM.
Background: The overall treatment response among patients with locally advanced pancreatic cancer (LAPC) is poorly understood as most studies report solely on resected patients. We aimed to investigate the outcomes in patients with LAPC as an intention-to-treat-analysis from the time of diagnosis from a complete source population.
Patients And Methods: An observational cohort study in a population-defined region within a universal healthcare system.
Article Synopsis
- Intraductal oncocytic papillary neoplasms (IOPNs) are now identified as distinct from intraductal papillary mucinous neoplasms (IPMNs), with limited information on their recurrence and survival outcomes.
- A study analyzed outcomes of 415 patients with invasive IOPNs and adenocarcinoma from IPMN over a median of 6 years, finding similar recurrence rates between invasive IOPNs and ductal A-IPMN, but poorer survival compared to colloid A-IPMN.
- The research concluded that invasive IOPNs behave like aggressive cancers, with adjuvant chemotherapy showing no significant impact on recurrence rates in any of the studied cancer types.
Introduction: Pancreatic neuroendocrine tumors (pNET) exhibit a wide spectrum of clinical behavior, which makes their assessment and management quite challenging. The purpose of this study was to comprehensively assess the existing treatment landscape for patients with pNET.
Materials And Methods: The study was conducted with the support of the ESSO-EYSAC Research Academy in collaboration with the E-AHPBA.
Article Synopsis
- Training in HPB surgery is inconsistent across regions under the E-AHPBA, leading to discussions about the future of accreditation for centers and fellowship programs.
- A mixed-methods study was conducted to gather responses from stakeholders, focusing on identifying strengths, weaknesses, opportunities, and threats (SWOT) related to the accreditation process.
- The findings highlight both positive and negative aspects affecting HPB accreditation and suggest that while formal accreditation isn't currently feasible, there's strong interest in developing a structured system for HPB training that should influence future strategic planning.
Article Synopsis
- The study aimed to determine the need for routine surveillance after pancreatic cancer surgery and to analyze surveillance practices in Nordic countries.
- A review of global clinical guidelines and a survey of 20 pancreatic units in Norway, Sweden, Denmark, and Finland revealed inconsistent recommendations and practices regarding postoperative follow-up.
- Despite most units conducting routine surveillance, evidence supporting long-term monitoring (up to 5 years) is limited and varies significantly between institutions.
Background: Laparoscopic appendectomy is a common procedure and introduced early in general surgical training. How internal (i.e.

However, even if adverse events were comparable, oncological endpoints including survival need to be confirmed in the next phase 3 study.

- The study examines the outcomes of different precursor epithelial subtypes of adenocarcinoma from intraductal papillary mucinous neoplasms (A-IPMN), focusing on clinical features and recurrence patterns among patients who underwent pancreatic surgery.
- A total of 297 patients were analyzed, revealing that gastric, pancreatobiliary, and mixed subtypes have similar outcomes that are worse than the intestinal subtype in terms of recurrence and overall survival.
- The research found that adjuvant chemotherapy specifically improved survival rates in the pancreatobiliary subtype, but not in gastric, intestinal, or mixed subtypes, indicating a potential area for further exploration in treatment strategies.
Article Synopsis
- - The study investigates factors affecting long-term survival and recurrence in patients with adenocarcinoma from intraductal papillary mucinous neoplasms, focusing on those who had pancreatic resection between 2010 and 2017 in Europe and Asia.
- - It analyzed data from 288 patients, revealing that 48% experienced recurrence within about 98 months, with 35% remaining disease-free at the 5-year mark.
- - Key negative predictors for long-term disease-free survival included multivisceral resection, tumor location in the pancreatic tail, poor differentiation, lymphovascular invasion, and perineural invasion, leading to the development of a predictive model with a good success rate.
Background: Biliary tract cancers comprise a heterogeneous collection of malignancies usually described as cholangiocarcinoma of the intra- or extrahepatic bile duct, including perihilar cholangiocarcinoma and gallbladder cancer.
Methods: A review of pertinent parts of the ESSO core curriculum for the UEMS diploma targets (Fellowships exam, EBSQ), based on updated and available guidelines for diagnosis, surgical treatment and oncological management of cholangiocarcinoma.
Results: Following the outline from the ESSO core curriculum we present the epidemiology and risk factors for cholangiocarcinoma, as well as the rationale for the current diagnosis, staging, (neo-)adjuvant treatment, surgical management, and short- and long-term outcomes.
