Introduction

The goals of treatment for metastatic castration-resistant prostate cancer are disease management, improving quality of life, and prolonging life. Although androgen-receptor blockade and chemotherapy can control the disease for several years in most patients, resistance to treatment and continued disease progression are inevitable. Radionuclides have emerged as important tools in the therapeutic arsenal against prostate cancer. Appropriate sequencing with existing standards of care is paramount to ensure that patients get the maximum clinical benefit from as many life-prolonging therapies as possible during the treatment journey.

Methods

We review radionuclide therapy for men with metastatic castration-resistant prostate cancer and present a treatment algorithm used in our specialist center to provide optimal care.

Results

The goal of the treatment algorithm employed in our specialist center is to provide optimal patient care by using and sequencing appropriate systemic radionuclide therapy. The first step is to determine the extent of disease and metastases to offer personalized treatment to extend survival. Appropriate treatment sequencing can allow men to receive the life-prolonging benefits of radium-223 immediately upon bone-only progression, while remaining eligible to benefit from chemotherapy and/or lutetium-177 vipivotide tetraxetan (177Lu-PSMA) upon further disease progression. Importantly, although prostate-specific antigen (PSA) is frequently perceived as a marker for prostatic disease burden, survival benefits of radionuclide therapy may be independent of change in PSA.

Conclusions

As the majority of men with metastatic castration-resistant prostate cancer first present with bone-only metastases, they may be treated initially with radium-223, while still remaining eligible to benefit from chemotherapy and 177Lu-PSMA upon subsequent progression of skeletal metastatic disease and/or the emergence of lymph node or visceral metastases.
