Abstract
PURPOSE: Initial heparinization followed by vitamin K antagonists is the treatment of choice for patients with venous thromboembolism. There is controversy whether known malignancy is a risk factor for recurrences and bleeding complications during this treatment. Furthermore, the incidence of such events in these patients is dependent on the achieved International Normalized Ratio (INR). The aim of this study was to assess the incidence of venous thromboembolic recurrence and major bleeding among patients with venous thromboembolism in relation to both malignancy and the achieved INR. PATIENTS AND METHODS: In a retrospective analysis, the INR-specific incidence of venous thromboembolic and major bleeding events during oral anticoagulant therapy was calculated separately for patients with and without malignancy. Eligible patients participated in two multicenter, randomized clinical trials on the initial treatment of venous thromboembolism. Patients were initially treated with heparin (standard or low-molecular weight). Treatment with vitamin K antagonists was started within 1 day and continued for 3 months, with a target INR of 2.0 to 3.0. RESULTS: In 1,303 eligible patients (264 with malignancy), 35 recurrences and 12 bleeds occurred. Patients with malignancy, compared with nonmalignant patients, had a clinically and statistically significantly increased overall incidence of recurrence (27.1 v 9.0, respectively, per 100 patient-years) as well as bleeding (13.3 v 2.1, respectively, per 100 patient-years). In both groups of patients, the incidence of recurrence was lower when the INR was above 2.0 compared with below 2.0. CONCLUSION: Although adequately dosed vitamin K antagonists are effective in patients with malignant disease, the incidence of thrombotic and bleeding complications remains higher than in patients without malignancy.

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.
