Excerpt
The theragnostic approach was proposed with the introduction of 131-Iodine for the treatment of both benign and malign thyroid diseases [
1‐
5]. The therapeutic effect of 131-Iodine is based on its ability to emit -particles, which are characterized by a high linear energy transfer (LET) and a relatively long range of penetration. The β-emission increases the average dose to the tumor, but it also results in irradiation of surrounding healthy tissue [
1‐
6]. During the last years, [
177Lu]Lu-PSMA-617 has been introduced as a promising and effective therapy in patients with prostate cancer and metastatic disease [
7‐
9]. Similarly, to 131-Iodine,
177Lu is a typical theragnostic agent, able to emit both β-particles and γ photons. The use of [
177Lu]Lu-PSMA-617 has been previously tested in several populations with metastatic castration-resistant prostate cancer (mCRPC). VISION study [
7], an important multicenter phase 3 randomized trial of 831 mCRPC patients, demonstrated that [
177Lu]Lu-PSMA-617 plus standard of care (SOC) significantly prolonged radiological progression-free survival (rPFS) (8.7 vs. 3.4, months) and overall survival (OS) (15.3 vs. 11.3, months) compared to control group of SOC patients. In addition, the quality of life was not adversely affected by this innovative and revolutionary therapy. …
