A fatal primary gastric melanoma treated by a double immunotherapy with ipilimumab/nivolumab: description of a case report. | LitMetric

AI Article Synopsis

Article Abstract

Background: Primary gastric melanoma (GM) is a very uncommon tumor with a poor prognosis. Until now, only a few cases have been reported in the literature.

Case Description: A 70-year-old, Caucasian, ex-smoker man, presented with asthenia, anorexia, and weight loss of 5 kg during the last 2 months. Biological test showed high levels of transaminases and a microcytic, hypochromic anemia. Whole body CT-scan documented a gastric tumor lesion with concomitant loco-regional lymph node and hepatic metastases. Histology was consisted with the diagnosis of a primary GM. A double immunotherapy with nivolumab and ipilimumab was started but, 2 weeks later, the patient presented an acute hepatic failure quickly leading to his death despite a high dose corticotherapy.

Conclusions: The particularity of this case relies on the rarity of GM, its difficult diagnosis representing a clinical challenge, and the complexity of its management that is not validated by large clinical trials, data being extrapolated from the treatment protocols routinely used in cutaneous melanoma. In our case, the patient died 2 weeks after the first cycle of a nivolumab/ipilimumab combined treatment for an acute hepatic failure that could be related to a treatment toxicity or a tumor hyperprogression. The patient's survival was very short not allowing any accurate evaluation of the efficacy of this therapy.

Application of pedicled supraclavicular flaps in hypopharyngectomy with preservation of laryngeal function.

BMC Surg

December 2024

Department of Otolaryngology Head and Neck Surgery, The Affiliated Hospital of Southwest Medical University, No.25, Taiping Street, Jiangyang District, Luzhou, 646000, China.

Objective: To evaluate the efficacy of pedicled supraclavicular flaps in hypopharyngectomy reconstruction, with a focus on preserving laryngeal function.

Methods: From August 2019 to June 2022, 14 patients with primary hypopharyngeal carcinoma who met the inclusion and exclusion criteria and underwent the repair of hypopharyngeal defects using pedicled supraclavicular flaps were included retrospectively. Relevant clinical evaluation indicators include patient characteristics, defect sizes, flap sizes, flap harvesting time, postoperative hospital stay, postoperative complications, recurrence, and survival outcomes.

Description: Gastric cancer (GC) is a leading cause of preventable cancer and mortality in certain US populations. The most impactful way to reduce GC mortality is via primary prevention, namely Helicobacter pylori eradication, and secondary prevention, namely endoscopic screening and surveillance of precancerous conditions, such as gastric intestinal metaplasia (GIM). An emerging body of evidence supports the possible impact of these strategies on GC incidence and mortality in identifiable high-risk populations in the United States.

Simulated Gastrointestinal Fluids Impact the Stability of Polymer-Functionalized Selenium Nanoparticles: Physicochemical Aspects.

Int J Nanomedicine

December 2024

Division of Medical Physics and Biophysics, Gottfried Schatz Research Center for Cell Signaling, Metabolism and Aging, Medical University of Graz, Graz, 8010, Austria.

Background: Selenium (Se) is a vital micronutrient for maintaining homeostasis in the human body. Selenium nanoparticles (SeNPs) have demonstrated improved bioavailability compared to both inorganic and organic forms of Se. Therefore, supplementing with elemental Se in its nano-form is highly promising for biomedical applications related to Se deficiency.

Objectives: To identify gaps in knowledge, attitude, and practice regarding the use of corticosteroids and nonsteroidal anti-inflammatory drugs (NSAIDs) among patients with chronic rheumatic diseases.

Methods: A cross-sectional study was conducted using a questionnaire including 12 knowledge questions, 13 attitude assessment statements, 5 barrier assessment statements, and 7 practical scenarios. We counted the total numbers of correct answers in knowledge, positive attitudes, barriers, and appropriate practices and fitted using Poisson regression to examine factors associated with knowledge, attitudes, and practices.
