Imply on diagnosis and early prognosis of preoperative [Ga]Ga-PSMA-11 PET/CT in patients with suspected brain tumours of glial origin.

PET/CT targeting prostate-specific membrane antigen (PSMA) is commonly used in patients with prostate cancer. PSMA has been found in other solid tumours, including primary brain tumours. The aim of this study was to evaluate the usefulness of [Ga]Ga-PSMA-11 PET/CT for preoperative diagnosis and 2-year prognosis.

68Ga-Prostate-Specific Membrane Antigen PET/CT in Endometrial Cancer: A Preliminary Report.

Purpose Of The Report: Endometrial cancer is the most common gynecological cancer. Prostate-specific membrane antigen (PSMA) is expressed in prostate cancer cells but can be found in other cancers, such as endometrial cancer, during angiogenesis.The aim of this prospective pilot study was to evaluate the feasibility of using 68Ga-PSMA-11 PET/CT in endometrial cancer patients before surgical treatment.

Quantized multi-task learning for context-specific representations of gene network dynamics.

While often represented as static entities, gene networks are highly context-dependent. Here, we developed a multi-task learning strategy to yield context-specific representations of gene network dynamics. We assembled a corpus comprising ~103 million human single-cell transcriptomes from a broad range of tissues and diseases and performed a two stage pretraining, first with non-malignant cells to generate a foundational model and then with continual learning on cancer cells to tune the model to the cancer domain.

Prostate-Specific Membrane Antigen Expression in Patients with Primary Prostate Cancer: Diagnostic and Prognostic Value in Positron Emission Tomography-Prostate-Specific Membrane Antigen.

Prostate cancer represents a significant public health challenge, with its management requiring precise diagnostic and prognostic tools. Prostate-specific membrane antigen (PSMA), a cell surface enzyme overexpressed in prostate cancer cells, has emerged as a pivotal biomarker. PSMA's ability to increase the sensitivity of PET imaging has revolutionized its application in the clinical management of prostate cancer.

Parathyroid Adenoma Detected in Ga-PSMA PET/CT but Not in the Dedicated Imaging Modalities.

Background: Primary hyperparathyroidism is a common endocrine disorder characterised by excessive parathormone secretion that results in hypercalcemia, primarily caused by parathyroid adenoma. Accurate localisation of hyperfunctioning tissue is essential for curative surgical treatment. Although conventional imaging modalities like ultrasonography and Tc-MIBI scintigraphy (SPECT) along with F-fluorocholine PET/CT are commonly employed, there are cases with false-negative imaging results.
