A recommendation from an independent data monitoring committee prompted the discontinuation of the phase 3 CAPItello-280 trial.

Data show that patients who undergo grade group 1 prostatectomies may experience an increased likelihood of higher risk features.

BMI, serum albumin, and G8 screening tool scores were all factors correlated with the likelihood of experiencing a grade 3 or higher AE.

Toxicity complications were assessed between single- and multiple-treatment modalities for patients with localized prostate cancer.

Administering 177Lu for mCRPC is a “team sport”, according to Steven Finkelstein, MD, DABR, FACRO.

After the recent approval of 177Lu in PSMA+/mCPRCP prior to chemotherapy, Steven Finkelstein, MD, DABR, FACRO, highlights the importance of this milestone.

Results from the KEYNOTE-921 trial demonstrated that pembrolizumab with docetaxel did not elicit efficacy improvements vs placebo with docetaxel in prostate cancer.

Multidisciplinary collaboration may help in minimizing the treatment burden among patients with prostate cancer, according to Curtiland Deville Jr, MD.

Panelists discuss how PSMA PET imaging plays a crucial role in detecting biochemical recurrence of prostate cancer, offering superior sensitivity and specificity compared with conventional imaging methods. In clinical practice, PSMA PET is typically ordered when there is a rise in prostate-specific antigen (PSA) levels post treatment, indicating potential recurrence. The imaging results significantly influence treatment decisions such as distinguishing between localized salvage therapy and systemic treatments. Pivotal trials have demonstrated the efficacy of various tracers.

Panelists discuss how PSMA PET imaging plays a crucial role in the initial staging of prostate cancer, offering superior accuracy over conventional methods. Medical professionals consider factors such as diagnostic performance, tracer availability, and patient-specific characteristics when selecting appropriate PSMA PET agents. The integration of PSMA PET findings into clinical practice has led to more precise treatment planning, potentially improving patient outcomes. Pivotal trials have demonstrated the efficacy of various PSMA PET tracers in detecting prostate cancer metastases.

The phase 3 MIRAGE trial findings show that PROSTOX ultra was validated as a biomarker to predict genitourinary toxicity following SBRT.

Focused, high-dose radiotherapy doses may prolong survival and the interval to subsequent therapy for patients with advanced prostate cancer.

Data show increasing use of proton therapy overall but widening gaps in populations who have access to this treatment, Curtiland Deville Jr, MD, says.

Panelists discuss how high-quality imaging is crucial for accurately staging prostate cancer, guiding treatment decisions, and optimizing patient outcomes. Superior resolution and sensitivity of PSMA PET tracers enhance lesion detection, influencing surgical, radiation, and systemic therapy choices. Differences in tracer properties impact specificity, affecting treatment planning. Advanced imaging reduces uncertainty, improving risk stratification and therapeutic precision.

Panelists discuss how medical professionals select PSMA PET tracers based on factors such as diagnostic accuracy, tracer availability, patient-specific considerations, and logistical aspects such as half-life and production facilities. Fluorine-18 (^18F)–labeled tracers, such as ^18F-PSMA-1007, offer logistical advantages due to their longer half-life and higher image resolution, facilitating broader clinical application.

Panelists discuss how PSMA PET imaging utilizes various tracers, each with distinct properties influencing image quality and diagnostic accuracy. Fluciclovine F18 (Axumin) is primarily used for detecting recurrent prostate cancer, offering moderate sensitivity but lower specificity compared with PSMA-targeted agents. Gallium Ga 68 gozetotide (Illuccix) provides high sensitivity and specificity for prostate cancer lesions; however, its shorter half-life and limited availability may restrict widespread use. Piflufolastat F18 (Pylarify) combines the benefits of F18’s longer half-life with high image resolution, enhancing detection accuracy. Similarly, flotufolastat F18 (Posluma) leverages F18’s favorable imaging characteristics, offering high-quality images and reliable lesion detection.

Panelists discuss how prospective randomized data, notably from Hofman et al (Lancet, 2020), demonstrate that PSMA PET-CT exhibits superior diagnostic accuracy compared with conventional imaging in detecting pelvic nodal and distant metastases in patients with high-risk prostate cancer. Conventional imaging techniques, such as CT and bone scans, often have lower sensitivity and specificity, potentially missing smaller or early metastatic lesions. In contrast, PSMA PET-CT offers enhanced sensitivity and specificity, leading to more precise staging and management decisions.

Results from PSMAfore show that lutetium Lu 177 vipivotide tetraxetan elicited a median rPFS of 9.3 months vs 5.6 months with ARPI in prostate cancer.

A cohort study found that pre-radical prostatectomy levels greater than 20 ng/mL were associated with increased all-cause mortality risk and prostate cancer-specific mortality risk.
