Abstract

fetched live from OpenAlex

Muscle-invasive bladder cancer is a common malignancy, and its standard of care treatment often involves neoadjuvant chemotherapy and radical cystectomy. These treatments are invasive and associated with significant mortality and morbidity. Neoadjuvant chemotherapy is associated with skeletal muscle atrophy and reduced body mass, while radical cystectomy is associated with high-risk blood loss necessitating blood transfusion.Despite an established relationship between androgens and prostate cancer, it is unclear whether androgens impact other types of cancer, including bladder cancer. In fact, decades of research on the relationship between anti-androgens and cancer prevention/treatment have provided conflicting or inconclusive results. Preoperative testosterone could prevent surgery-related skeletal muscle atrophy and help maintain normal hematocrit levels. Preoperative testosterone is an inexpensive and feasible intervention and seems to improve postoperative recovery with minimal adverse effects in different patient populations.To date, no clinical trial has been conducted evaluating preoperative testosterone in bladder cancer patients. In this review, we present a rationale for the use of preoperative testosterone in bladder cancer patients, which we believe may serve as the basis for the development of a future clinical trial.

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.

Not 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.
