Testosterone administration to men with testosterone deficiency syndrome after external beam radiotherapy for localized prostate cancer: preliminary observations
Bibliographic record
Abstract
OBJECTIVE: To assess the effects of testosterone supplementation in men with testosterone deficiency syndrome (TDS) after external beam radiotherapy (EBRT) for localized prostate cancer. PATIENTS AND METHODS: Five men with significant signs of TDS after treatment for localized prostate cancer with EBRT were treated with testosterone once their prostate-specific antigen (PSA) level had reached the nadir. RESULTS The mean (range) level of testosterone before supplementation was 5.2 (1.1-9.2) nmol/L and the duration of follow-up while on supplementation was 14.5 (6-27) months. At the last visit, the testosterone levels were 17.6 (8.5-32.4) nmol/L. One of the five patients had a transitory increase in PSA level but none had levels of >1.5 ng/mL. All patients reported a marked response in the manifestations of TDS, i.e. four each reported decreased hot flushes, decreased fatigue and improved libido, and two reported improved erectile function. CONCLUSION: Men with TDS after EBRT for localised prostate cancer are candidates for testosterone therapy. The patients must be aware of the advantages and disadvantages of the treatment. PSA levels must have reached a nadir before starting treatment and the follow-up must be particularly close. In these few patients there were no adverse effects from testosterone supplementation. There is a need for more information about the safety and efficacy of testosterone therapy in men successfully treated for localized prostate cancer, because there is evidence indicating hypogonadism in these patients, compromising their quality of life and longevity, independent of the cancer.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
