Should a biopsy be obtained prior to surgery in children with pancreatic masses? A case report describing the difficult journey of an adolescent undergoing treatments for a rhabdomyosarcoma of the head of the pancreas following primary pancreaticoduodenectomy for a suspected solid pseudopapillary tumor
Bibliographic record
Abstract
Pancreaticoduodenectomy, a procedure rarely performed in children, can lead to significant morbidity. Rhabdomyosarcoma is the most frequent soft tissue sarcoma in pediatrics. Treatment consists of chemotherapy, while local control can be achieved through either surgery, radiotherapy or both. In this brief report, we describe the case of a 15-year-old adolescent who underwent a pancreaticoduodenectomy for a presumed solid pseudopapillary tumor of the head of the pancreas, ultimately diagnosed as a fusion-positive rhabdomyosarcoma. We review the ensuing severe side effects of the treatments, and discuss the role of biopsies for pancreatic tumors in pediatrics.

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.
