Ostéosarcome primitif du rein avec évolution métastatique au foie.Étude de cas et revue de la littérature
Bibliographic record
Abstract
L’ostéosarcome primitif du rein est une pathologie très rare dontl’histogénèse n’est pas claire. Les récidives locales et les métastasessont fréquentes et le pronostic est très mauvais. Nous décrivons icile cas d’une patiente de 59 ans qui présentait des douleurs lombairesgauches et un amaigrissement. Une échographie abdominaleet une tomodensitométrie abdominale ont révélé une masserétropéritonéale de 13 × 8 × 9 cm avec macrocalcifications. Lebilan d’extension n’a pas révélé d’autres lésions. On a procédé àune néphrectomie élargie gauche; l’examen histologique a révéléune prolifération tumorale constituée de cellules fusiformes de taillevariable, ces cellules manifestement atypiques produisant directementdu tissu ostéoïde évoquant un ostéosarcome rénal. Dix moisplus tard, la patiente présentait des lésions métastatiques au niveauhépatique sans autre lésion secondaire ni récidive locale. La patienteest actuellement en cours de traitement par chimiothérapie pardoxorubicine et cisplatine avec un recul de 17 mois. Les caractéristiquesanatomocliniques et les modalités thérapeutiques decette pathologie rare sont discutées ci-dessous.Primary osteosarcoma of the kidney is very rare. Its exact histogenesisremains unclear. It has a tendency to recur locally and metastasize,and the prognosis is very poor. We present a case of a59-year-old woman with left flank pain and weight loss. Abdominalultrasonography and bone scan revealed a large solid retroperitonealmass with calcifications. The patient underwent radicalnephrectomy; microscopic examination showed atypical cells withthe characteristic pattern of classic osteosarcoma with immatureneoplastic osteoid. Ten months later, the patient developedmetastatic lesions in the liver, without local recurrence or othersites of metastases. The patient is currently receiving chemotherapywith doxorubicin and cisplatin, with a follow-up in 17 months.The most important clinical findings, the pathogenesis and thetreatment modalities of this rare neoplasm are discussed.

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.
