Value of [F]FDG PET/CT parameters of the primary tumor in assessing overall survival in NSCLC patients with cN1-cN3 lymph nodes involvement.

Background: The aim of this retrospective study was to assess the value of F-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography ([F]FDG PET/CT parameters in cN1-cN3 non-small cell lung cancer (NSCLC) patients.

Materials And Methods: 59 consecutive patients (35 M, 24 F) with NSCLC who underwent pretreatment [F]FDG PET/CT were enrolled to this study. Several primary tumor PET parameters, including the maximum and mean standardized uptake value (SUV and SUV, the metabolic active tumor volume (MTV) and the total lesion glycolysis (TLG = MTVxSUV), were extracted and analysed.

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.

Evaluation of Prostate-Specific Membrane Antigen (PSMA) Immunohistochemical Expression in Early-Stage Breast Cancer Subtypes.

Breast cancer, known for its diverse subtypes, ranks as one of the leading causes of cancer-related deaths. Prostate-specific membrane antigen (PSMA), primarily associated with prostate cancer, has also been identified in breast cancer, though its role remains unclear. This study aimed to evaluate PSMA expression across different subtypes of early-stage breast cancer and investigate its correlation with clinicopathological factors.

[F]fluorodeoxyglucose positron emission tomography/computed tomography in combination with clinical data in predicting overall survival in non-small-cell lung cancer patients: A retrospective study.

Introduction: Positron emission tomography/computed tomography (PET/CT) has an established role in evaluating patients with lung cancer. The aim of this work was to assess the predictive capability of [F]Fluorodeoxyglucose ([F]FDG) PET/CT parameters on overall survival (OS) in lung cancer patients using an artificial neural network (ANN) in parallel with conventional statistical analysis.

Methods: Retrospective analysis was performed on a group of 165 lung cancer patients (98M, 67F).
