The Role of [F]FDG PET and Clinicopathologic Factors in Detecting and Predicting Bone Marrow Involvement in Non-Hodgkin Lymphoma.

: This study evaluates the diagnostic accuracy of [18F]fluorodeoxyglucose ([F]FDG) positron emission tomography (PET) using bone marrow biopsy (BMB) and clinical follow-up as reference standards. It further identifies predictive factors for bone marrow involvement (BMI) in non-Hodgkin lymphoma (NHL) patients. : NHL patients who underwent [F]FDG PET and BMB at diagnosis in a tertiary cancer center were included in this study.

First Clinical Experience of Ga-FAPI PET/CT in Tertiary Cancer Center: Identifying Pearls and Pitfalls.

Over the past four years, Ga-fibroblast activation protein inhibitor (FAPI) positron emission tomography/computed tomography (PET/CT) has been established at a tertiary cancer care facility in Jordan. This retrospective study aims to explore tracer uptake metrics across various epithelial neoplasms, identify diagnostic pitfalls associated with Ga-FAPI PET/CT, and evaluate the influence of Ga-FAPI PET/CT staging results on changes in therapeutic intent compared to gold standard molecular imaging modalities. A total of 48 patients with biopsy-confirmed solid tumors underwent 77 Ga-FAPI PET/CT examinations for molecular imaging assessment, encompassing neoplasms originating from the gastrointestinal tract, head and neck, hepatobiliary system, pancreas, breast, and lung.

Therapeutic Challenges in Metastatic Castration-Resistant Prostate Cancer: A Case Study and Review of Prostate-Specific Membrane Antigen-Targeted Therapy Failures in Highly Prostate-Specific Membrane Antigen-Avid Disease.

Prostate cancer (PCa) is a leading cause of cancer-related deaths globally, with metastatic castration-resistant prostate cancer (mCRPC) posing significant treatment challenges. This case report discusses a 65-year-old male with mCRPC who initially responded to hormonal therapy but later showed disease progression despite additional chemotherapy. He subsequently received Lu-PSMA and Ac-PSMA therapies, both of which failed to halt disease progression despite having an intense PSMA avid metastatic disease.

Exploring utilities of [64Cu]Cu-DOTA-trastuzumab immunoPET in breast cancer: a systematic review and meta-analysis.

[64Cu]Cu-DOTA-trastuzumab represents a novel immunopositron emission tomography (immunoPET) agent with emerging diagnostic applications in human epidermal growth factor receptor-2 (HER2)-expressing breast cancer (BC). This systematic review and meta-analysis evaluates the current diagnostic utilities of [64Cu]Cu-DOTA-trastuzumab PET/computed tomography (CT) and explores tumor uptake metrics in HER2-positive BC lesions. A systematic literature search of PubMed, Scopus, and Ovid databases was conducted using relevant keywords to identify eligible studies.

Angiotensin-Converting Enzyme 2 (G8790A) Gene Polymorphism as a Risk Factor for COVID-19 in Egyptian Children and Adolescents.

Objective: Recently, angiotensin-converting enzyme 2 (ACE2) gene has emerged as a potential candidate gene for susceptibility to SARS-CoV-2 infection. We investigated whether ACE2 G8790A (rs2285666) polymorphism could be a genetic marker for susceptibility to COVID-19 and disease severity in Egyptian children and adolescents.

Methods: This was a prospective case-control study included 580 cases diagnosed with COVID-19, and 580 matched control children and adolescents.
