A Spatially Directed Microneedle Patch Enables Intratumoral Co‐Delivery of FOLFIRINOX, Surufatinib, and Anti‐PD‐1 for Chemo‐Immunotherapy of Pancreatic Ductal Adenocarcinoma

Advanced Science, EarlyView.
A double‐layered shell‐core microneedle patch is developed to co‐deliver FOLFIRINOX, surufatinib, and anti‐PD‐1 for localized chemo‐immunotherapy of PDAC. This strategy achieves sustained tumor suppression, reduces metastasis, and reprograms the TME by enhancing CD8+ T‐cell infiltration and inhibiting Tregs and M2 macrophages infiltration, while ...

Deep Learning‐Assisted Coherent Raman Scattering Microscopy

Advanced Intelligent Discovery, EarlyView.
The analytical capabilities of coherent Raman scattering microscopy are augmented through deep learning integration. This synergistic paradigm improves fundamental performance via denoising, deconvolution, and hyperspectral unmixing. Concurrently, it enhances downstream image analysis including subcellular localization, virtual staining, and clinical ...

Total Neoadjuvant Treatment for Esophageal Adenocarcinoma With Oligometastases: TNT‐OES‐1 Trial

International Journal of Cancer, EarlyView.
Total neoadjuvant therapy could combine the potentially strong systemic effect of FLOT chemotherapy with the good locoregional control of CROSS chemoradiotherapy. While total neoadjuvant therapy is increasingly used in rectal cancer, its potential in gastroesophageal cancer remains largely unexplored.

Comparison of Relapse Risk Prediction Models During Active Surveillance in Stage I Seminoma: A Retrospective Multicenter Cohort Study

International Journal of Cancer, EarlyView.
ABSTRACT To improve the prediction of relapse for clinical stage I seminoma, we aimed to validate the Boormans model (incorporating tumor size, rete testis invasion, and lymphovascular invasion) against the conventional classification (tumor size > 4 cm/rete testis invasion).
