Collecting duct of Bellini renal carcinoma with psoas muscle recurrence: A case report and review of literature
Bibliographic record
Abstract
Collecting duct carcinoma (CDC) is a rare type of renal carcinoma with an aggressive course and poor treatment response. Up to date, there are only few reports of CDC, which may be due to unrecognized or unfamiliarity of its features and characteristics. We report a case of CDC in a 63-year-old male who initially presented with localized disease, and developed psoas muscle metastasis 15 months after partial nephrectomy with good surgical margins. No guidelines currently exist for the management of CDC; however, aggressiveness of the disease warrants close surveillance and consideration of adjuvant therapy even in patients with localized tumours. We postulate that CDC in its localized stage can be managed by partial nephrectomy, while preserving renal function; however, it is also important to consider a good oncologic outcome by administering adjuvant therapy, such as chemotherapy, and targeted therapy for a better prognostic outcome.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
