Embracing the Practical Aspects of Theranostics With Prostate-Specific Membrane Antigen–Targeted Lutetium-177
Bibliographic record
Abstract
Treatment options for men with metastatic castration-resistant prostate cancer are rapidly changing. In addition to novel anti-androgens and taxane-based chemotherapy, radiopharmaceuticals are having an increasing role. Although calcium-mimetic theranostics have been in use for years, newer approaches use molecularly targeted radiation therapy by conjugating isotopes to prostate-specific membrane antigen (PSMA) and in so doing directly target prostate cancer cells; 177Lutetium-PSMA-617 is perhaps the best-known member of this new class. Expanding our capacity to deliver targeted beta-emitters requires additional planning and equipment. Having delivered close to 200 doses of 177Lutetium-PSMA-617 at our center, we offer practical advice about patient selection, radiation safety, treatment administration, and toxicity monitoring. Although this blueprint is not the only way to expand a theranostics program beyond Radium-223, we offer our institutional experience with 177Lutetium-PSMA-617 as an example to programs seeking to expand their radiopharmaceutical programs. We must rise to meet the patient-driven demand for these innovative and effective therapies.

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.
