Liquid biopsies in pancreatic cancer: targeting the portal vein
Bibliographic record
Abstract
Abstract Pancreatic cancer is a highly lethal malignancy with poor overall survival due to silent progression until primary tumor growth or metastatic dissemination develops clinical symptoms. Even in the minority of patients with early diagnosis and candidacy for curative intent surgery, postoperative recurrence after surgical resection is very frequent. Due to these findings, efforts to identify minimally invasive ways to provide earlier diagnosis and enhanced prognostication are increasingly warranted. Liquid biopsies assessing for tumor derived materials shed into the blood are a promising tool to accomplish this goal; however, in pancreatic cancer, peripheral blood analyses remain dependent on the degree of tumor burden with a prohibitively low yield until the cancer is widely metastatic. To overcome this limitation, increasing literature has emerged evaluating the possibility of portal venous blood as a new, potentially higher yield liquid biopsy target in pancreatic cancer. This review will discuss the current literature and clinical application potential of mesenteric vasculature, or portal venous blood, as liquid biopsies in the diagnosis, prognosis and management of patients with pancreatic cancer.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
