Implications of pregnancy on MCN of the pancreas: A multicentric case-control study.

Background: Mucinous cystic neoplasms (MCN) of the pancreas express estrogen and progesterone receptors. Several case reports describe MCN increasing in size during gestation. The aim of this study is to assess if pregnancy is a risk factor for malignant degeneration of MCN.

Value of Surgical Cytoreduction in Patients with Small Intestinal Neuroendocrine Tumors Metastatic to the Liver and Peritoneum.

Background: Cytoreductive hepatectomy can improve survival and symptoms of hormonal excess in patients with small intestinal neuroendocrine tumor (siNET) liver metastases, but whether to proceed when peritoneal metastases are encountered at the time of planned cytoreductive hepatectomy is controversial.

Methods: This was a retrospective review of patients who underwent surgical management of metastatic siNETs at Mayo Clinic between 2000 and 2020. Patients who underwent cytoreductive operation for isolated liver metastases or both liver and peritoneal metastases were compared.

Outcomes of Neoadjuvant Chemotherapy for Invasive Intraductal Papillary Mucinous Neoplasm Compared with de Novo Pancreatic Adenocarcinoma.

Background: The management of invasive intraductal papillary mucinous cystic neoplasm (I-IPMN) does not differ from de novo pancreatic ductal adenocarcinoma (PDAC); however, I-IPMNs are debated to have better prognosis. Despite being managed similarly to PDAC, no data are available on the response of I-IPMN to neoadjuvant chemotherapy.

Methods: All patients undergoing pancreatic resection for a pancreatic adenocarcinoma from 2011 to 2022 were included.

Cancer "Avatars": Patient-Derived Xenograft Growth Correlation with Postoperative Recurrence and Survival in Pancreaticobiliary Cancer.

Background: Pancreaticobiliary (PB) cancers are a diverse group of cancers with poor prognoses and high rates of recurrence after resection. Patient-derived xenografts (PDX), created from surgical specimens, provide a reliable preclinical research platform and high-fidelity cancer model from which to study these malignancies with consistent recapitulation of their original patient tumors in vivo. However, the relationship between PDX engraftment success (growth or no growth) and patient oncologic outcomes has not been well studied.

Technical Outcomes of Porto-Mesenteric Venous Reconstruction in Pancreatic Resection Using Autologous Left Renal Vein Graft as Conduit.

Background: Portal or superior mesenteric vein (PV-SMV) resection and reconstruction is sometimes required during pancreatic tumor resection. In patients requiring segmental venous resection with interposition grafting, the left renal vein (LRV) is an accessible autologous solution. However, long-term patency outcomes of the LRV as an interposition conduit in this setting have not been analyzed.

Non-anatomical liver resection for hepatocellular carcinoma: the SegSubTe classification to overcome the problem of heterogeneity.

Background: The superiority of anatomical resection (AR) vs. non-anatomical resection (NAR) in the surgical management of hepatocellular carcinoma (HCC) is debated. ARs are well-defined procedures, whereas the lack of NAR standardization results in heterogeneous outcomes.

Mixed Acinar Neuroendocrine Carcinoma of the Pancreas: Comparative Population-Based Epidemiology of a Rare and Fatal Malignancy in The United States.

Mixed acinar neuroendocrine carcinoma of the pancreas (MANEC-P) is an extremely rare malignancy with a poor prognosis. However, epidemiological estimates of MANEC-P remain unknown. This study aimed to estimate and compare the incidence, prevalence, and cancer-specific survival (CSS) of MANEC-P in the United States (US).

COVID-19 and Liver Surgery: How the Pandemic Affected an Italian Medium-Volume HBP Center.

Introduction: While the COVID-19 pandemic is still ongoing, it is even more evident that victims of the pandemic are not only those who contract the virus, but also the countless patients suffering from other serious diseases (i.e., tumor) who have undergone delayed potentially life-saving surgery due to a lack of beds.

Impact of the Proactive Rounding Team on Rapid Response System During COVID-19 Pandemic: A Retrospective Study From an Italian Medical Center.

Objective: During the coronavirus disease 2019 (COVID-19) pandemic a proactive rounding (PR) team was introduced in our clinical practice in order to recognize the clinical deterioration of the patient as soon as possible. This study aimed to evaluate the impact of the PR team on the rapid response system (RRS) workload with particular regard to the activity carried out, the mode of intervention, and the outcome of patients.

Methods: In this retrospective study, the first period before the activation of the PR team (March 1, 2019, to February 29, 2020) and the second period after its activation (March 1, 2020, to March 1, 2021) were compared.

The use of ace inhibitors influences the risk of progression of BD-IPMNs under follow-up.

Background: Chemoprevention's ability to slow down or prevent the progression of BD-IPMNs is extremely appealing. Aspirin (ASA), Ace Inhibitors/Angiotensin Receptor Blockers (ACEIs/ARBs) and Statins (STATs) are frequently prescribed drugs with a possible beneficial effect on different cancer types. Their effect on IPMNs is largely unknown.

Skeletal muscle wasting and long-term prognosis in patients undergoing rectal cancer surgery without neoadjuvant therapy.

Background: Derangement of body composition has been associated with dismal long-term survival in several gastrointestinal cancers including rectal tumors treated with neoadjuvant therapies. The role of specific preoperative anthropometric indexes on the oncologic outcomes of patients undergoing upfront surgery for rectal cancer has not been investigated. The aim of the study is to evaluate the association of body composition and overall survival in this specific cohort.

Pancreatic Cystic Neoplasms and Pregnancy: A Systematic Review of Surgical Cases and a Case Report of a Fully Laparoscopic Distal Pancreatectomy.

Background: Mucinous cystic neoplasms and solid pseudopapillary neoplasms are the most common pancreatic tumors occurring in women of fertile age and in pregnant women. The aim of this study is to provide an updated literature review on this association and to present a fully laparoscopic resection of a pregnancy-associated pancreatic cystic neoplasm.

Materials And Methods: A systematic literature review was performed using PubMed (MEDLINE), Scopus, Ovid, ISI Web of Science, and Google Scholar for searching.

A tug-of-war in intraductal papillary mucinous neoplasms management: Comparison between 2017 International and 2018 European guidelines.

Background: 2017 International and 2018 European guidelines are the most recent guidelines for intraductal papillary mucinous neoplasms management.

Aim: to evaluate the diagnostic accuracy of these guidelines in identifying malignant IPMN.

Methods: data from resected patients with IPMN were collected in two referral centers.

Pancreatic cystic neoplasms: What is the most cost-effective follow-up strategy?

Pancreatic cystic neoplasms are one of the most frequent incidental findings in the field of pancreatic diseases, estimated to be present in up to 45% of the general population. They represent an heterogeneous group of tumors with different biological behavior and variable risk of progression to malignancy. While serous cystadenomas (SCAs) have no risk of malignant progression, mucinous cyst adenoma are malignant in 20% of cases and this risk is higher in intraductal papillary mucinous neoplasms (IPMN).
