Role of nutritional care and general guidance for patients with advanced or metastatic gastric cancer

Patients with advanced or metastatic gastric cancer often suffer from malnutrition, which can have an impact on quality of life, increase the toxicity of chemotherapy and reduce overall survival. Options available to the clinician to manage a patient’s nutritional status include screening and assessment of malnutrition at diagnosis, monitoring during the ‘cancer journey’, early detection of precachexia and the ongoing use of a multidisciplinary team (oncologists, other medical specialists and nutritionists). Because malnutrition is frequently overlooked and under treated in patients with advanced or metastatic gastric cancer, this narrative review focuses on the clinical meaning of nutritional status in gastric cancer and provides general guidance regarding nutritional care management for patients with advanced or metastatic gastric cancer. Patients with gastric cancer that has spread to other parts of the body often suffer from malnutrition. This can impact patients’ lives, increase side effects from cancer treatment and reduce life expectancy. This article provides guidance for healthcare providers on nutritional care for patients with gastric cancer. Key ways healthcare providers can contribute to nutritional care include: looking for malnutrition when a patient is diagnosed with gastric cancer; watching carefully for malnutrition during cancer treatment; keeping a lookout for early signs of extreme weight loss and muscle wasting; and involving a team of healthcare providers with a broad range of expertise in patients’ nutritional care.
