Atezolizumab-Induced Sarcoid-Like Granulomatous Reaction in a Patient with Urothelial Cell Carcinoma
Bibliographic record
Abstract
A 61-year-old woman with locally advanced, high-grade urothelial cell carcinoma was treated with the anti-programmed death-ligand 1 antibody atezolizumab. She initially received neoadjuvant chemotherapy and surgery that led to clinical and radiographic remission at the time of atezolizumab initiation. Within 3 months she developed new mediastinal and hilar lymphadenopathy as well as pulmonary nodules in a pattern characteristic of pulmonary sarcoidosis. Mediastinal lymph node biopsy by endobronchial ultrasound demonstrated noncaseating granulomas without evidence of malignancy or infection. Within 4 weeks of initiation of prednisone and cessation of atezolizumab there was marked reduction in intrathoracic lymphadenopathy and perilymphatic nodules. This is the first reported case of atezolizumab-induced sarcoid-like granulomatous reaction.

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.
