Rats (FLF1) were pretreated with 2 and 20 mg/kg/day fluvastatin (Flu), and after 6 weeks, hepatocellular tumor cells were inoculated under the left renal capsule. At different times, growth and pyruvate kinase (PK) activity of the primary tumors and lymph node metastases were determined. Flu had a dose-dependent inhibitory effect on primary and metastatic tumors, and the inhibitory effect on growth and PK activity in metastases were higher than in primary tumors. Finally, Flu had an earlier inhibitory effect on the early appeared PK activity in metastases than in primary tumors.

Background: Central nervous system tumors (CNSTs) represent a significant oncological challenge in pediatric populations, particularly in developing regions where access to diagnostic and therapeutic resources is limited.
Methods: This research investigates the epidemiology, histological classifications, and survival outcomes of CNST in a cohort of pediatric patients aged 0 to 19 years within a 25-year retrospective study at the Civil Hospital of Guadalajara, Mexico, from 1999 to 2024.
Results: Data was analyzed from 273 patients who met inclusion criteria, revealing a higher incidence in males (51.
Ruthenium-106 brachytherapy and central uveal melanoma.
Int Ophthalmol
January 2025
Department of Ophthalmology, Staedtisches Klinikum Dessau, Brandenburg Medical School Theodor Fontane, Dessau, Germany.
Purpose: Uveal melanoma (UM) is the most common primary ocular malignancy. The size and location of the tumor are decisive for brachytherapy with the β-emitting ruthenium-106 (Ru-106) plaque. The treatment of juxtapapillary and juxtafoveolar UM may be challenging because of the proximity or involvement of the macula and optic nerve and high recurrence rates.

Department of Radiology, The First Affiliated Hospital of Guangxi Medical University, No. 6 Shuangyong Road, Nanning, 530021, Guangxi, China.
Purpose: This case report aims to present a rare case of endometrial carcinosarcoma, a highly malignant tumor with a poor prognosis. The primary objective is to describe this unique case's clinical presentation, multimodal magnetic resonance imaging (MRI) features, typical histopathological characteristics and surgical treatment.
Methods: A detailed analysis of the patient's medical history, preoperative imaging evaluation, and treatment approach was conducted.
The Society of Thoracic Surgeons (STS) Clinical Practice Guideline on Surgical Management of Oligometastatic Non-small Cell Lung Cancer.
Ann Thorac Surg
January 2025
Thoracic Surgery Service, Department of Surgery, Memorial Sloan Kettering Cancer Center, New York, New York.
Background: The use of local consolidative therapy (LCT) in patients with oligometastatic non-small cell lung cancer (NSCLC) is rapidly evolving, with a preponderance of data supporting the benefits of such therapeutic approaches incorporating pulmonary resection for appropriately selected candidates. However, practices vary widely institutionally and regionally, and evidence-based guidelines are lacking.
Methods: The Society of Thoracic Surgeons assembled a panel of thoracic surgical oncologists to evaluate and synthesize the available evidence regarding the role of pulmonary resection as LCT.

January 2025
Department of Otolaryngology-Head and Neck Surgery, Louisiana State University Health Sciences Center, Shreveport, Louisiana, U.S.A.
Objective: To identify the most effective treatment modality for achieving favorable outcomes in early glottic tumors with anterior commissure involvement (ACI).
Data Sources: PubMed, Embase, Web of Science, and ScienceDirect.
Review Methods: Random-effects proportional meta-analysis model is used to evaluate the oncological and functional outcomes of transoral laser microsurgery (TLM) versus radiation therapy (RT) in early glottic (T1-T2) cancer with ACI.
