Gaining a new angle on pancreas cancer: A pre-operative thrombelastographic parameter predicts recurrence and survival among patients with resected periampullary and pancreatic adenocarcinoma.

Background: It has previously been demonstrated that Thrombelastography(TEG) angle may be associated with recurrence and survival in pancreas cancer in a cohort of patients operated on at the University of Colorado in 2016-2017. Now approaching 10 years of follow-up, we revisit these associations and strengthen these claims with multivariate analysis.

Methods: Retrospective chart review was performed.

Computed tomography-derived normative values and z-scores of the pulmonary valve annulus and sino-tubular junction in the pediatric population.

Background: Accurate assessment of the pulmonary valve can dictate clinical management of patients with right ventricular outflow tract (RVOT) anomalies. Comparisons with available normal reference values are essential for accurate evaluation. The aim of the study was to generate normative data for the pulmonary valve annulus and sino-tubular (ST) junction using CT measurements derived from a heterogeneous pediatric population and create z-scores useful for clinical practice.

Adjuvant Chemotherapy With or Without Radiotherapy for Resected Pancreatic Cancer After Multiagent Neoadjuvant Chemotherapy.

Background: Adjuvant therapy is associated with improved pancreatic cancer survival after neoadjuvant chemotherapy and surgery. However, whether adjuvant treatment should include radiotherapy is unclear in this setting.

Methods: This study queried the National Cancer Database for pancreatic adenocarcinoma patients who underwent curative resection after multiagent neoadjuvant chemotherapy between 2010 and 2019 and received adjuvant treatment.

The United States experience with diagnosing and treating esophageal cancer during the SARS-CoV-2 pandemic: A retrospective cohort study.

The downstream effects on healthcare delivery during the initial wave of the COVID-19 pandemic remain unclear. The purpose of this study was to determine how the healthcare environment surrounding the pandemic affected the oncologic care of patients diagnosed with esophageal cancer. This was a retrospective cohort study evaluating patients in the National Cancer Database (2019-2020).

Analyzing the impact of the Coronavirus disease 2019 pandemic on initial oncologic presentation and treatment of non-small cell lung cancer in the United States.

Background: A significantly lower rate of non-small cell lung cancer (NSCLC) screening, greater health care avoidance, and changes to oncologic recommendations were some consequences of the Coronavirus disease 2019 (COVID-19) pandemic affecting the medical environment. We sought to determine how the health care environment during the COVID-19 pandemic affected the oncologic treatment of patients diagnosed with non-small cell lung cancer (NSCLC).

Methods: This was a retrospective cohort study evaluating patients with NSCLC in the National Cancer Database (2019-2020).

Predictive ability of pancreatic cyst fluid biomarkers: A systematic review and meta-analysis.

Background: Mucinous pancreatic cysts harbor the potential to progress to highly lethal pancreatic ductal adenocarcinoma (PDAC). Since these precursor cysts require cancer surveillance or surgical resection, they need to be reliably distinguished from harmless pancreatic cysts. Current clinical and radiographic assessment is imperfect and the value of cyst fluid analysis for differential diagnosis is unclear.

Management of Localized Small- and Large-Cell Pancreatic Neuroendocrine Carcinoma in the National Cancer Database.

Background: The role of curative-intent resection and perioperative chemotherapy for nonmetastatic pancreatic neuroendocrine carcinoma (PanNEC) remains unclear due to their biological aggressiveness and rarity. This study aimed to evaluate the association of resection and perioperative chemotherapy with overall survival for nonmetastatic PanNEC.

Study Design: Patients with localized (cT1-3, M0), small- and large-cell PanNEC were identified in the National Cancer Database from 2004 to 2017.

Evaluation of Survival Following Surgical Resection for Small Nonfunctional Pancreatic Neuroendocrine Tumors.

Importance: The number of patients with small nonfunctional pancreatic neuroendocrine tumors (NF-PanNETs) is increasing. However, the role of surgery for small NF-PanNETs remains unclear.

Objective: To evaluate the association between surgical resection for NF-PanNETs measuring 2 cm or smaller and survival.

Comparison of Invasive Pancreatic Ductal Adenocarcinoma versus Intraductal Papillary Mucinous Neoplasm: A National Cancer Database Analysis.

Background: Current evidence on overall survival (OS) between invasive pancreatic ductal adenocarcinoma (PDAC) and intraductal papillary mucinous neoplasm (IPMN) is limited to single-center reports. We aimed to compare the characteristics, management, and OS of invasive PDAC vs. IPMN using a national United States (US) database.

Prevalence and progression of intraductal papillary mucinous neoplasms of the pancreas in solid organ transplant recipients: A systematic review.

Solid organ transplantation (SOT) recipients are known to carry an increased risk of malignancy because of long-term immunosuppression. However, the progression of intraductal papillary mucinous neoplasm of the pancreas (IPMN) in this population remains unclear. We performed a systematic review by searching PubMed, Embase, Scopus, and Google Scholar.

Association of Adjuvant Chemotherapy in Patients With Resected Pancreatic Adenocarcinoma After Multiagent Neoadjuvant Chemotherapy.

Importance: The total number of patients with pancreatic ductal adenocarcinoma (PDAC) who receive neoadjuvant chemotherapy (NAC) is increasing. However, the added role of adjuvant chemotherapy (AC) in these patients remains unknown.

Objective: To evaluate the association of AC with overall survival (OS) in patients with PDAC who received multiagent NAC followed by curative-intent surgery.

Unmeasured factors are associated with the use of completion lymph node dissection (CLND) in melanoma.

Background: Completion lymph node dissection (CLND) was the standard treatment for patients with melanoma with positive sentinel lymph nodes (SLN) until 2017 when data from the DeCOG-SLT and MLST-2 randomized trials challenged the survival benefit of this procedure. We assessed the contribution of patient, tumor and facility factors on the use of CLND in patients with surgically resected Stage III melanoma.

Methods: Using the National Cancer Database, patients who underwent surgical excision and were found to have a positive SLN from 2012 to 2017 were included.

Validating a risk assessment tool in United Kingdom and Irish paediatric cardiac catheterisation practice.

Background: No established risk prediction tool exists in United Kingdom and Irish Paediatric Cardiology practice for patients undergoing cardiac catheterisation. The Catheterisation RISk score for Paediatrics is used primarily in North American practice to assess risk prior to cardiac catheterisation. Validating the utility and transferability of such a tool in practice provides the opportunity to employ an already established risk assessment tool in everyday practice.

Ductal Dilatation of ≥5 mm in Intraductal Papillary Mucinous Neoplasm Should Trigger the Consideration for Pancreatectomy: A Meta-Analysis and Systematic Review of Resected Cases.

Intraductal papillary mucinous neoplasms (IPMN) are common but difficult to manage since accurate tools for diagnosing malignancy are unavailable. This study tests the diagnostic value of the main pancreatic duct (MPD) diameter for detecting IPMN malignancy using a meta-analysis of published data of resected IPMNs. Collected from a comprehensive literature search, the articles included in this analysis must report malignancy cases (high-grade dysplasia (HGD) and invasive carcinoma (IC)) and MPD diameter so that two MPD cut-offs could be created.
