Association of HAMP Expression and CD8+ T‐Cell Infiltration With Atezolizumab–Bevacizumab Response in Hepatocellular Carcinoma

Annals of Gastroenterological Surgery, EarlyView.
In hepatocellular carcinoma treated with atezolizumab–bevacizumab, responders showed RNA‐seq enrichment of immune and chemokine pathways with higher HAMP expression. In resected specimens, immunohistochemistry confirmed increased intratumoral CD8+ T‐cell density and hepcidin (HAMP), supporting HAMP plus CD8 as components of a composite predictor of ...

Preoperative Gemcitabine/Nab‐Paclitaxel With Concurrent Radiation Therapy for Borderline Resectable Pancreatic Cancer: A Comparative Analysis With Preoperative Chemoradiation Therapy Using Gemcitabine Alone

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background Although NCCN guidelines recommend preoperative therapy for borderline resectable pancreatic cancer (BR‐PC), it is still unclear which regimen is better. The study objective was to elucidate the prognostic significance of neoadjuvant chemoradiotherapy (NACRT) with gemcitabine/nab‐paclitaxel (GnP‐RT) compared to gemcitabine alone ...
