This is a structured narrative review synthesizing evidence and international guidelines on surgical management of borderline resectable pancreatic cancer in the neoadjuvant therapy era, offering a practical decision-making framework rather than reporting original trial data.
A single case report with clinical narrative describing an unusual metastatic pattern; it raises mechanistic hypotheses and clinical management questions but provides no comparative data, control group, or generalizable evidence.
Single-centre retrospective measurement study with no clinical outcome; demonstrates a technical phenomenon (tissue shrinkage) but lacks comparison to patient safety or oncological adequacy thresholds.
