PSMA therapy under more restrictive regimen of 4-week intervals

PSMA therapy under more restrictive regimen of 4-week intervals

How oft is the Lu-PSMA treatment conducted? The usual cycle consists of 3 sessions with 6 to 8 weeks interval in-between. Our more restrictive treatment regimen of initial 3 cycles with an interval of only 4 weeks in-between demonstrated >80% response rates even in heavily pre-treated patientsThis treatment does not care, “where” the metastases are: lymph nodes, bone, lungs, liver or even tumor in the prostate region itself. The usual “victims” of PSMA ligands, the salivary glands and kidneys, are not significantly affected under this regimen.

Ga-68 demonstrates superiority to F-18 in digital PSMA-PET/CT scans for staging prostate cancer

Gallium-68 has demonstrated superiority to Fluorine-18 in digital PSMA-PET/CT scans for staging prostate cancer

Fluorine-18 is a commonly used isotope utilized for conducting PSMA-PET/CT to stage prostate cancer, due to its longer half-life and higher production capacity as compared to Gallium-68. The latest study, however, has demonstrated superiority of Ga-68, because of the focal unspecific uptake of F-18 in the bones of ribs and pelvis. Without additional follow-up exams or any morphological correlates, this may be misinterpreted as bone metastasis. While nonspecific uptake in other tissues and physiologic uptake in the ganglia can be filtered out, unspecific bone uptake tends to lead to false interpretation and misdiagnosis. Bone metastases do occur in 10% of patients with the newly diagnosed prostate cancer, and 80-90% of patients in the advanced stage. Over-staging the patient may result in inadequate therapy decisions, especially in case of early biochemical recurrence. Read more.

PSMA therapy improves health-related quality of life in patients with prostate cancer

¹⁷⁷Lu-PSMA therapy improves health-related quality of life in patients with mCRPC

On Friday, 17 September 2021, Novartis announced further positive findings from the VISION trial: 177Lu-PSMA-617 therapy delays worsening of physical functioning and the onset of pain symptoms in patients with mCRPC. Hence, beyond extending overall survival and progress-free period, this Breakthrough Therapy also improves health-related quality of life. Read more

NCCN Guidelines add PSMA-PET imaging for prostate cancer

National Comprehensive Cancer Network, an alliance of cancer centers in the US, whose guidelines in oncology are applied to treating cancers, has added 68Ga-PSMA-PET imaging to its clinical practice guidelines for prostate cancer. Moreover, it recognized the high precision of this diagnostic tool as a primary stand-alone method and scrapped conventional imaging as a necessary prerequisite for PSMA-PET.

Working group headed by Prof. Markus Hartenbach was able to demonstrate the outstanding diagnostic value of PSMA PET / MRI in biopsy-proven prostate cancer

Working group headed by Prof. Markus Hartenbach was able to demonstrate the outstanding diagnostic value of PSMA PET / MRI in biopsy-proven prostate cancer.

PSMA-PET/MRI can provide an accurate staging of newly diagnosed prostate cancer. In addition, treatment strategies were changed in almost a third of the patients due to the information of this hybrid imaging technique. The scientific paper was published in the Clinical Cancer Research.

Working group under Prof. Hartenbach MD demonstrates superiority of PSMA PET in diagnosing recurring prostate cancer

The working group headed by Prof. Markus Hartenbach MD was able to demonstrate the superiority of PSMA PET in the diagnosis of biochemical recurrence of prostate cancer, even at low PSA levels. Moreover, this diagnostic tool adds significant information to standard CT/MRI, changing treatment strategies in a significant number of patients. PSMA-positive lesions were detected in 85.5% patients, whereas 57.3% had no suspicious correlates according to the MRI or CT reports. Detection rates were 65% for a PSA value of 0.2 to <0.5 ng/ml, 85.7% for 0.5 to <1, 85.7% for 1 to <2 and 100% for ≥2. PSMA-PET changed therapeutic decisions in 74.6% of the patients (p < 0.001), with 86% of them being considered for metastases-directed therapies. The scientific paper was published in the “European Journal of Nuclear Medicine and Molecular Imaging”.
