Single-cell multi-omic analysis of fibrolamellar carcinoma reveals rewired cell-to-cell communication patterns and unique vulnerabilities.

Fibrolamellar carcinoma (FLC) is a rare malignancy disproportionately affecting adolescents and young adults with no standard of care. FLC is characterized by thick stroma, which has long suggested an important role of the tumor microenvironment. Over the past decade, several studies have revealed aberrant markers and pathways in FLC.

Evaluating surgeon communication of pancreatic cancer prognosis using the VitalTalk ADAPT framework.

Background And Objectives: Few data exist to guide optimal communication practices for surgical oncologists. VitalTalk, an evidence-based communication skills training model for clinicians, offers the five-step ADAPT tool for discussing prognosis. This study aimed to characterize surgeon communication of pancreatic cancer prognosis using VitalTalk's ADAPT framework.

Prophylactic somatostatin analogs for postoperative pancreatic fistulas: a cross-sectional survey of AHPBA surgeons.

Background: Postoperative pancreatic fistulas lead to substantially increased morbidity, mortality, and healthcare costs after pancreatectomy. Studies have reported conflicting data on the role of prophylactic somatostatin analogs in the reduction of postoperative pancreatic fistula. Current practice patterns, surgeon beliefs, and barriers to using these drugs in the Americas is not known.

Enhanced Complement Expression in the Tumor Microenvironment Following Neoadjuvant Therapy: Implications for Immunomodulation and Survival in Pancreatic Ductal Adenocarcinoma.

Background: Neoadjuvant therapy (NAT) is increasingly being used for pancreatic ductal adenocarcinoma (PDAC) treatment. However, its specific effects on carcinoma cells and the tumor microenvironment (TME) are not fully understood. This study aims to investigate how NAT differentially impacts PDAC's carcinoma cells and TME.

Intratumoral T-cell receptor repertoire composition predicts overall survival in patients with pancreatic ductal adenocarcinoma.

Pancreatic ductal adenocarcinoma (PDAC) is a lethal malignancy that is refractory to immune checkpoint inhibitor therapy. However, intratumoral T-cell infiltration correlates with improved overall survival (OS). Herein, we characterized the diversity and antigen specificity of the PDAC T-cell receptor (TCR) repertoire to identify novel immune-relevant biomarkers.
