Extended Patient Survival after Inferior Vena Cava Stent Placement for Obstruction Caused by Metastatic Colon Cancer
Bibliographic record
Abstract
Venous obstruction by malignancy is a significant cause of morbidity. Stenting of superior or inferior vena cava obstruction can be very effective in improving symptoms. In some cases, patients who are considered palliative may become eligible for active cancer treatment as a result of the relief of their venous obstruction. In this report, we describe the case of a patient with advanced colon cancer with a large right hepatic lobe metastatic lesion severely compressing the suprarenal inferior vena cava (IVC) resulting in extensive venous collaterals, abdominal wall distension and edema of both lower extremities. Initial treatment with chemotherapy were unsuccessful. The patient was deemed not suitable for further treatment due to her poor performance status. A 24 mm x 70 mm Wallstent venous endoprosthesis was inserted under ultrasound guidance resulting in a rapid improvement in the patient's symptoms of abdominal pain and anasarca.

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.
