Abstract

We report our initial real-world experience with 177Lu-PSMA-617 radioligand therapy. Methods: We performed a retrospective review of patients treated with 177Lu-PSMA-617. Pretreatment PSMA PET, laboratory findings, overall survival, a fall in prostate-specific antigen by 50% (PSA50), and toxicities were evaluated. Results: Ninety-nine patients were included. Sixty patients achieved a PSA50. Seven of 18 (39%) patients who did not meet the TheraP PSMA imaging criteria achieved a PSA50. Nineteen of 31 (61%) patients who did not meet the VISION laboratory criteria achieved a PSA50. Sixty-three patients had a delay or stoppage in therapy, which was due to a good response in 19 patients and progressive disease in 14 patients. Of 10 patients with a good response who restarted treatment, 9 subsequently achieved a PSA50 on retreatment. The most common toxicities were anemia (33%) and thrombocytopenia (21%). Conclusion: At our center, patients who did not meet the TheraP PSMA imaging criteria or the VISION laboratory criteria benefited from 177Lu-PSMA-617 radioligand therapy.

Keywords: 177Lu-PSMA-617; genitourinary; oncology; radionuclide therapy; toxicities.

(A) Restricted mean OS in patients who did not fulfill TheraP PSMA imaging criteria was 12.7 mo, vs. 12.4 mo in patients who met TheraP PSMA imaging criteria. (B) Restricted mean PSA PFS in patients who did not fulfill TheraP PSMA imaging criteria was 4.8 mo, vs. 6.0 mo in patients who met TheraP PSMA imaging criteria.

(A) Restricted mean OS in patients who met VISION laboratory criteria was 13.9 mo, vs. 9.7 mo in patients who did not. (B) Restricted mean PSA PFS in patients who met VISION laboratory criteria was 5.7 mo, vs. 6.0 mo in patients who did not. Patients with baseline laboratory issues had similar PSA response but decreased OS, compared with patients who did not have baseline laboratory issues.
