Surgical Management of a Large Well-Differentiated Liposarcoma in the Supraclavicular Fossa: A Case Report.

Liposarcomas originating in the supraclavicular fossa are exceptionally rare, with only a few documented cases in the medical literature. We present a unique case involving a remarkably large indolent, atypical lipomatous tumor or well-differentiated liposarcoma situated in the right supraclavicular region, measuring 18 cm × 18 cm × 17 cm. To our knowledge, this represents the largest liposarcoma found in the supraclavicular fossa reported in the literature.

Beta-Blocker Use Is Associated With Worse Relapse-Free Survival in Patients With Head and Neck Cancer.

Purpose: Although beta-blockers (BBs) have been hypothesized to exert a beneficial effect on cancer survival through inhibition of beta-adrenergic signaling pathways, clinical data on this issue have been inconsistent. We investigated the impact of BBs on survival outcomes and efficacy of immunotherapy in patients with head and neck squamous cell carcinoma (HNSCC), non-small-cell lung cancer (NSCLC), melanoma, or squamous cell carcinoma of the skin (skin SCC), independent of comorbidity status or cancer treatment regimen.

Methods: Patients (N = 4,192) younger than 65 years with HNSCC, NSCLC, melanoma, or skin SCC treated at MD Anderson Cancer Center from 2010 to 2021 were included.

Nerve Density and Neuronal Biomarkers in Cancer.

Certain histologic characteristics of neurons, novel neuronal biomarkers, and nerve density are emerging as important diagnostic and prognostic tools in several cancers. The tumor microenvironment has long been known to promote tumor development via promoting angiogenesis and cellular proliferation, but new evidence has shown that neural proliferation and invasion in the tumor microenvironment may also enable tumor growth. Specific neuronal components in peripheral nerves and their localization in certain tumor sites have been identified and associated with tumor aggressiveness.

Acetylcholine in Carcinogenesis and Targeting Cholinergic Receptors in Oncology.

Tumor cells modulate and are modulated by their microenvironments, which include the nervous system. Accumulating evidence links the overexpression and activity of nicotinic and muscarinic cholinergic receptor subtypes to tumorigenesis in breast, ovarian, prostate, gastric, pancreatic, and head and neck cancers. Nicotinic and muscarinic receptors have downstream factors are associated with angiogenesis, cell proliferation and migration, antiapoptotic signaling, and survival.

Comparative Analysis of Secondary Outcomes in Treatment of Charcot Neuropathy: A Systematic Review.

Background: Charcot neuroarthropathy (CN) is commonly associated with diabetic neuropathy and can predispose patients to amputations. Management remains a challenge, with no definitive treatment. This study examines major postoperative complications associated with open reduction with internal (intramedullary) nails, fixation, external fixation, or combined internal and external fixation for correction of the deformity.

β-Adrenergic signaling in skin cancer.

Activation of the sympathetic nervous system releases catecholamines that can interact with β-adrenergic receptors on tumor cells. Preclinical models have shown that the signaling processes initiated by activation of β-adrenergic receptors increase tumorigenesis, stimulate cell proliferation, and inhibit apoptosis. Indeed, preclinical studies have also shown that β-adrenergic blockade can decrease tumor burden.

A pharmacological evidence for the presence of antihistaminic and anticholinergic activities in Roxb.

Objective: The study was designed to evaluate possible antihistaminic and anticholinergic activities of .
