Osimertinib-Induced Unilateral Diffuse Alveolar Hemorrhage in a Patient With Pulmonary Adenocarcinoma
Bibliographic record
Abstract
A 70-year-old man with lung adenocarcinoma was admitted to our hospital due to progressive dyspnea, 4 months after osimertinib initiation. His chest radiograph and computed tomography revealed ground-glass opacities and consolidations dominantly in the upper left lung. He took neither antiplatelet nor anticoagulation agent. No abnormality in coagulation was detected. Bronchoalveolar lavage fluid (BALF) became serially and increasingly hemorrhagic, and confirmed the diagnosis of alveolar hemorrhage. After steroid pulse therapy and withdrawal of osimertinib, his condition gradually improved, accompanied by regression of ground-glass opacities and consolidations. Osimertinib causes not only interstitial pneumonia but also alveolar hemorrhage. The consolidations may spread not bilaterally, but be localized unilaterally. We have to keep this rare adverse event in mind, and consider immediate withdrawal of osimertinib and treatment with steroid. Increased lymphocytes in the BALF may be a potential indicator of sensitivity to steroid and favorable prognosis in diffuse alveolar hemorrhage.

Full frame machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
