Renal cell carcinoma with inferior vena caval extention: impact of tumour extent on surgical outcome
Bibliographic record
Abstract
OBJECTIVE: To evaluate our experience with surgical resection of renal cell carcinoma (RCC) with inferior vena cava (IVC) involvement and examine the relationship between prognosis and tumour extent. PATIENTS AND METHODS: A retrospective review of nephrectomy performed between 1985 and 2005 identified 50 patients presenting with tumour thrombus extension into the IVC. Clinical characteristics and outcome were evaluated. RESULTS: Of the 50 patients evaluated, 7, 26, 10 and 7 presented with level I, II, III and IV thrombus, respectively. Major postoperative complications occurred in 16% of patients. Local or distant failure occurred in 25 (64%) patients. The mean time to recurrence was 10 months. Only supra-diaphragmatic extension of the tumour thrombus was predictive of disease recurrence. CONCLUSION: Locally advanced RCC with IVC thrombus remains associated with significant local and distant failure rate. The level of thrombus extension is significantly associated with disease recurrence. Effective adjuvant therapy is needed to improve outcome in this patient population.

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.
