Carcinosarcoma of the bladder: case report and review of the literature
Bibliographic record
Abstract
Primary osteosarcomas of the bladder account for about 0.04% ofbladder neoplasms. Most of the patients in the literature expiredwithin 6 months and, in almost all of the cases in the literature,radical cystectomy with postoperative chemotherapy was thetreatment choice. A 79-year-old gentleman presented with grosshematuria. Cystoscopy demonstrated a 2- to 3-cm tumour along thelateral wall of the bladder. The tumour was resected incompletelyvia initial transurethral resection of bladder tumour (TURBT), anda second TURBT was subsequently performed to fully resect theresidual mass. Surgical pathology from these 2 resections revealedosteosarcoma with invasion into the muscularis propria. Acystoprostatectomy was performed and final pathologic specimenrevealed high-grade CIS without evidence of residual osteosarcoma.Postoperatively, the patient did not receive chemotherapy orradiation and currently remains disease-free 2 years post-radicalcystectomy. Only 33 well-documented cases of primary osteosarcomaof the bladder have been reported to date. However, thereare only 3 cases in which TURBT resulted in complete resection.

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.
