The Bone Scan Flare Phenomenon in Non–Small-Cell Lung Cancer
Bibliographic record
Abstract
PURPOSE: The bone scan flare phenomenon, defined as an increase in the number or intensity of bone lesions with subsequent improvement while the patient is receiving chemotherapy, has been described in solid tumors including breast cancers and small-cell lung cancers. The purpose of this study was to verify the existence of the bone scintigraphic flare phenomenon in patients with non-small-cell lung cancer (NSCLC) during chemotherapy and thus determine the utility of bone scintigraphy in the follow-up of these patients. MATERIALS AND METHODS: Thirty-three patients with NSCLC with bone metastases and who had been treated with chemotherapy were included in the study. The outcome of bone scintigraphy was compared with that in other neoplastic sites. RESULTS: The flare phenomenon was considered likely in 8 of the 33 patients. It was confirmed in two patients, invalidated in four, and remained doubtful in two. CONCLUSIONS: The bone flare phenomenon occurs in NSCLC. It renders bone scintigraphy less useful in the evaluation of tumoral response in the patients in whom it is considered likely.

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.
