To establish and validate a nomogram based on clinical characteristics and metabolic parameters derived from F-fluorodeoxyglucose positron emission tomography and computed tomography (F-FDG PET/CT) for prediction of high-grade patterns (HGP) in invasive lung adenocarcinoma. The clinical and PET/CT image data of 311 patients who were confirmed invasive lung adenocarcinoma and underwent pre-treatment F-FDG PET/CT scan in Beijing Hospital between October 2017 and March 2022 were retrospectively collected. The enrolled patients were divided into HGP group (196 patients) and non-HGP group (115 patients) according to the presence and absence of HGP.

: Malignant pleural effusions (MPEs) pose a significant challenge in clinical practice and exert a considerable socio-economic burden on the healthcare system, affecting approximately 1 million individuals annually. These effusions are a leading cause of debilitating dyspnea and a diminished quality of life among cancer patients, with distant metastasis to the pleural layers occurring in about 20% of cases during treatment. : A cross-sectional, observational case-control study was conducted on 151 Bulgarian patients with a hydrothorax.

Objective: Urinary proteins are effective tumor biomarkers. Human epididymis protein 4 (HE4), progastrin-releasing peptide (ProGRP), carcinoembryonic antigen (CEA), cytokeratin-19 fragment 21-1(CYFRA 21-1), and neuron-specific enolase (NSE) in serum, were proposed as tumor biomarkers of lung cancer. Our aim was to identify the urine protein biomarkers that can distinguish patients with lung cancer from healthy individuals and/or patients with benign lung disease with a high level of sensitivity and specificity.

Background: Thoracic SMARCA4-deficient undifferentiated tumors (SMARCA4-UT) exhibit a notably aggressive phenotype, which is associated with poor patient survival outcomes. These tumors are generally resistant to conventional cytotoxic chemotherapy, thereby limiting the availability of effective treatment options.
Case Presentation: We describe a 69-year-old AIDS patient who initially presented with a fused, enlarged lymph node on the right clavicle and mild, unexplained pain under the right axilla that worsened with severe coughing episodes.
