A 65-year-old woman was diagnosed with rheumatoid arthritis in 2010 and was treated with methotrexate (MTX). In 2012, she was diagnosed with sarcoidosis and underwent a follow-up therapy for mild peripheral neuropathy due to neurosarcoidosis. In 2018, she experienced primary splenic diffuse large B-cell lymphoma (DLBCL) and was diagnosed with sarcoidosis-lymphoma syndrome (SLS). MTX was discontinued, and six cycles of rituximab were administered combined with chemotherapy. Positron emission tomography combined with computed tomography performed 18 weeks after the last cycle of chemotherapy showed new abnormal fluoro-2-deoxy-D-glucose (FDG) uptake in the mediastinal and hilar lymph nodes and skeletal muscles. Sarcoidosis was suspected because of increased serum angiotensin-converting enzyme levels and magnetic resonance imaging findings in the lower limb muscles. However, pathological findings of DLBCL and sarcoidosis were not confirmed in the hilar lymph node biopsy. Therefore, malignant lymphoma can be distinguished from sarcoidosis using abnormal FDG uptake after chemotherapy for SLS.

Purpose: Breast cancer ranks as the most prevalent cancer in women, characterized by heightened fatty acid synthesis and glycolytic activity. Fatty acid synthase (FASN) is prominently expressed in breast cancer cells, regulating fatty acid synthesis, thereby enhancing tumor growth and migration, and leading to radioresistance. This study aims to investigate how FASN inhibition affects cell proliferation, migration, and radioresistance in breast cancer, as well as the mechanisms involved.

Immune checkpoint inhibitors (ICIs) frequently cause immune-related adverse events (irAEs), with thyroid irAEs being the most common endocrine-related irAEs. The incidence of overt thyroid irAEs ranged 8.9-22.

Objectives: The objective is to evaluate the efficacy of F-fluorodeoxyglucose positron emission tomography (F-FDG-PET) computed tomography (CT) in the evaluation of tumor response to preoperative/palliative chemoradiotherapy (CRT) for advanced colorectal cancer; including metastatic cancer at primary presentation and recurrent cancers with local and/or distant metastasis.
Materials And Methods: Fifty patients with advanced rectal cancer underwent two point imaging with 18 FDG PET-CT before and after 3 weeks of completion of preoperative/palliative CRT in between 2016 and 2022. Patients with locally recurrent cancer also underwent radical surgery.

Background: Parkinson's disease (PD) is one of the most common neurodegenerative disorders. Previous research has confirmed that isofraxidin can reduce macrophage expression and inhibit peripheral inflammation. However, its effects on the central nervous system remain underexplored.
