Abstract:

We present the case of a 55-year-old man with HER2-positive, AFP-producing gastric cancer and multiple liver metastases. The patient consequently underwent 7 courses of SOX plus trastuzumab therapy, 3 courses of weekly PTX plus ramucirumab therapy, and 3 courses of nivolumab therapy, all of which resulted in PD. Obstruction due to tumor growth became noticeable 9 months after the start of the first treatment. Subsequently, the patient experienced malnutrition and systemic edema due to impaired oral intake. However, subsequent trastuzumab deruxtecan(T-DXd)therapy induced remarkable tumor shrinkage. Furthermore, oral intake became possible, and edema started subsiding. Thus, we report the course of a patient with AFP-producing gastric cancer and stenosis who regained oral intake capabilities after T-DXd treatment.

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Enteral Nutrition I: Orogastric and Nasogastric Feeding

Enteral Nutrition I: Orogastric and Nasogastric Feeding

Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Barrett Esophagus-II: Clinical Manifestations and Management

Barrett Esophagus-II: Clinical Manifestations and Management

Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure...
