ABSTRACT Semaglutide, a glucagon-like peptide-1 receptor agonist, used for Type 2 diabetes mellitus and more recently for weight loss, often causes gastrointestinal adverse effects such as delayed gastric emptying and abdominal discomfort. Current literature has not described an associated case of gastric pneumatosis with semaglutide use. We report a 61-year-old man on semaglutide for 9 months with gastric pneumatosis. Symptoms resolved on discontinuation. Clinicians should be vigilant for significant gastrointestinal adverse effects, including pneumatosis with semaglutide use.

Background: Myxoid liposarcoma predominantly affects young and middle-aged individuals, and little is known regarding treatment tolerability and outcomes in older patients. This study aims to better understand this older patient population. Methods: This single institution retrospective study included patients aged 70 years and older with localized (non-metastatic) myxoid liposarcoma. Results: Sixteen patients were included. The median age was 75 years, and 9 (56%) were female. Fourteen (88%) were extremity tumors and two (12%) were trunk. The median tumor size was 10.4 cm (range, 3.6 to 28 cm). Five (31%) tumors had a round cell component. All patients had surgery. Fourteen (88%) had perioperative radiation, and three (19%) had perioperative chemotherapy. One patient had postoperative infection, and one patient had neutropenic fever from preoperative chemotherapy. The median follow up from surgery was 6.3 years. Eight (50%) patients died from MLPS. The median relapse-free survival and overall survival were 34 months and 75 months, respectively. Conclusions: Most older patients with localized MLPS received perioperative radiation therapy with surgery, and few serious toxicities were reported. Even with treatment, half of the patients relapsed.
