Abstract

fetched live from OpenAlex

Patients with cancer have high risks of venous thromboembolism (VTE) as well as thrombocytopenia. Thrombocytopenia is associated with an increased risk of bleeding. Hence, treatment of acute VTE with anticoagulation is challenging in patients with cancer and thrombocytopenia. Data are limited in the management of this condition, and there are no randomized controlled trials (RCTs) available. The strategies for anticoagulation in patients with thrombocytopenia and cancer-associated thrombosis pilot trial (NCT05255003) is an open-label pilot RCT to evaluate the feasibility of a full-scale trial in this population. Adult patients with acute cancer-associated thrombosis within 14 days and thrombocytopenia (platelet count < 50,000/μL) are randomly assigned to 2 treatment arms as follows: (1) modified-dose low-molecular-weight heparin based on a predefined regimen to adjust dose by platelet count; or (2) platelet transfusion with a higher dose low-molecular-weight heparin regimen. The primary feasibility outcome is the overall average number of patients recruited per month. The main clinical outcomes include clinically relevant bleeding events (composite of major bleeding and clinically relevant nonmajor bleeding) and objectively confirmed recurrent VTE. This trial has the potential to define care in patients with acute cancer-associated thrombosis and thrombocytopenia. In this article, we present the rationale and design of the pilot trial and highlight several unique aspects of the study.

Not 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.
