Experience of Palliative Radiotherapy for Tumor-Associated Bleeding From Biliary Tract Cancer
Bibliographic record
Abstract
We experienced two cases of palliative radiotherapy (RT) for tumor-associated bleeding from biliary tract cancer (BTC). Bleeding due to tumor invasion to the duodenum wall caused severe anemia that required a blood transfusion. Hemostatic RT with 30 Gy in 10 - 12 fractions was attempted. Hemostasis was achieved in both patients, and they were able to spend their remaining life at home with no restrictions of their oral intake. In addition, no adverse events were seen in any of the two patients after undergoing palliative RT. Palliative RT for tumor-associated bleeding from BTC is suggested not only to be an effective and safe treatment option, but to improve the patient’s quality of life. The further accumulation of cases will be required in order to confirm the usefulness of hemostatic RT for BTC. J Med Cases. 2018;9(10):328-331 doi: https://doi.org/10.14740/jmc3064e

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
