Background: When Cox regression models are used to analyse time-to-event data, the proportional hazard assumption (PHA) must be reassured to obtain valid results. Transparent reporting of the statistics used is therefore essential to interpret research. This study aimed to assess the quality of statistical reporting and testing of the PHA in subgroup analysis of surgical randomised controlled trials (RCTs).

- 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.
Article Synopsis
- 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.
Article Synopsis
- A study was conducted to determine the effects of adjuvant chemotherapy on patients with adenocarcinoma from intraductal papillary mucinous neoplasia after surgical resection, analyzing data from 459 patients across 18 centers between 2010 and 2020.
- The results showed that 59.9% of patients received various chemotherapy regimens, but there was no significant difference in recurrence rates or survival outcomes between those who received chemotherapy and those who did not.
- Overall, the study concluded that adjuvant chemotherapy does not appear to improve recurrence patterns or survival rates in this patient population.
Article Synopsis
- The study aimed to compare long-term cancer outcomes between patients with adenocarcinoma from intraductal papillary mucinous neoplasms (A-IPMN) and pancreatic ductal adenocarcinoma (PDAC) after surgical resection.
- Data revealed that A-IPMN patients generally had better survival rates and lower recurrence rates compared to PDAC patients, including longer median survival (39.0 months for A-IPMN vs. 19.5 months for PDAC).
- While A-IPMN showed higher rates of peritoneal and lung recurrence, PDAC had more locoregional recurrences, but overall, systemic recurrence rates were similar between the two groups.
Article Synopsis
- The study investigates recurrence patterns and treatment outcomes following pancreatic surgery for adenocarcinoma originating from intraductal papillary mucinous neoplasms (IPMN), involving 459 patients from multiple centers between 2010 and 2020.
- Recurrences were seen in 45.5% of patients, with a significant portion occurring within the first year, while the type of treatment did not significantly affect recurrence rates or survival based on location of the recurrence.
- Overall survival improved for patients receiving additional treatment post-recurrence, with a median survival of 27.0 months compared to 14.6 months without further treatment.
Background: In patients with neuroendocrine liver metastasis (NELM), liver transplantation (LT) is an alternative to liver resection (LR), although the choice of therapy remains controversial. In this multicenter study, we aim to provide novel insight in this dispute.
Methods: Following a systematic literature search, 15 large international centers were contacted to provide comprehensive data on their patients after LR or LT for NELM.
Objectives: Ki-67, a marker of cellular proliferation, is associated with prognosis across a wide range of tumours, including gastroenteropancreatic neuroendocrine neoplasms (NENs), lymphoma, urothelial tumours and breast carcinomas. Its omission from the classification system of pulmonary NENs is controversial. This systematic review sought to assess whether Ki-67 is a prognostic biomarker in lung NENs and, if feasible, proceed to a meta-analysis.

While low- and intermediate-grade pancreatic NET (PanNET) and small intestinal NET (siNET) are slow growing, they have a relatively high rate of metastasizing to the liver, leading to substantially worse outcomes. In many solid tumours, the outcome is determined by the quality of the antitumour immune response.

- Pancreatic neuroendocrine tumors (PanNETs) are rare but increasingly detected, often incidentally in asymptomatic patients.
- The European Neuroendocrine Tumor Society suggests a conservative "watch and wait" approach, but the best surgical method for small tumors remains unclear, with parenchyma-sparing surgeries having higher morbidity risks.
- This study aims to identify pre-operative clinical predictors, like tumor size, that indicate which patients have a lower risk of lymph node metastases, potentially making them suitable candidates for less invasive surgical options.
Pancreatic neuroendocrine tumours (PNET) is a rare disease and in the absence of metastases, surgical resection is recommended. Key factors affecting survival in PNETs are the stage and grade of the disease, but there is increasing evidence suggesting lymph node involvement is associated with shorter disease-free and overall survival. Ability to predict the likelihood of lymph node involvement at the time of diagnosis would affect surgical decision making in these patients.

This systematic review along with meta-analysis will be conducted to assess the prognostic/grading utility of Ki-67 in Lung-NETs.
Methods: This systematic review will be conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines.
Gallstones are a common cause of morbidity in the elderly. Operative treatment is often avoided due to concerns about poor outcomes but the evidence for this is unclear. We aim to consolidate available evidence assessing laparoscopic cholecystectomy outcomes in the extreme elderly (>80s) compared to younger patients.

Obese trauma patients present particular challenges across the entirety of the patient care pathway, and are at risk of higher lengths of stay, morbidity, and mortality. This study sought to assess a national group of trauma experts' opinions and knowledge regarding the management of obese trauma.
