Introduction COPD is associated with a high prevalence of comorbid conditions, including lung cancer, cardiovascular diseases, metabolic diseases, and musculoskeletal diseases. 1 There is a growing clinical interest in the manifestations of COPD in organs other than the lungs, particularly the gastrointestinal tract. For example, Rutten et al 2 provided evidence of associated intestinal , Abstract Gastric metastases from lung adenocarcinoma are rare. Because gastric metastasis grossly resembles advanced gastric cancer, it is difficult to diagnose gastric metastasis especially when the histology of the primary lung cancer is adenocarcinoma., Gastric metastasis is an infrequent occurrence, especially when derived from lung adenocarcinomas. They can grossly resemble advanced gastric cancer and require comprehensive evaluations of the patients and their symptoms. Here, we present the case , Lung cancer cells often spread to the stomach via the bloodstream. This kind of spread from lung adenocarcinoma is rare but highlights how cancer can progress. Patients should know the possible signs, including stomach pain and general GI discomfort. Continued care and monitoring are vital for those with metastatic lung cancer. Healthcare teams play a key role in supporting patients through , Owing to the potential role of the gut-lung axis in carcinogenesis, we assessed the incidence of gastric cancer in patients with chronic obstructive pulmonary disease (COPD)., Find out why some people with chronic obstructive pulmonary disease (COPD) can get stomach problems like too much gas and bloating, and what you can do if it happens to you..
