Colonic Perforation Associated with Necrotizing Fasciitis in a Patient Receiving Tyrosine Kinase Inhibitor (Pazopanib) for Recurrent Retroperitoneal Renal Cell Carcinoma
Bibliographic record
Abstract
Pazopanib, under the trade name of votrient, is a potent tyrosine-kinase growth factor receptor inhibitor used in the treatment of late-stage kidney cancer and soft tissue sarcoma. Rarely this drug has been associated with gastrointestinal perforations; however, prior studies have not shown an association with necrotizing fasciitis. We present a case of suspected pazopanib-induced extensive colonic perforation resulting in a severe necrotizing fasciitis. As this is a potentially rare complication of this targeted therapy, our goal is to heighten the awareness of colonic perforation as it is only seen in 0.9% of patients on pazopanib. The staged operative management and multidisciplinary approach throughout this patient’s care allowed for complete recovery from a life-threatening diagnosis.

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.
