Course Description:

Malnutrition is a common yet frequently underrecognized during cancer care. Depending on the screening method and patient population, malnutrition or risk of malnutrition may affect up to 60% of individuals with cancer. Despite this high prevalence, routine nutrition screening remains inconsistently implemented across oncology settings.  

This educational resource explores the critical role of nutrition throughout the cancer care continuum using a case-based approach. Through the case of Jane, a 52-year-old woman with newly diagnosed gastric cancer, the program demonstrates how nutrition risk can exist even in individuals with obesity and highlights the importance of evaluating weight loss, reduced food intake, and functional decline rather than relying solely on body mass index (BMI).   

The resource reviews key contributors to cancer-associated malnutrition, including reduced food intake, gastrointestinal obstruction, treatment-related symptoms, inflammation, and cancer-related muscle loss. It also introduces validated nutrition screening tools commonly used in oncology practice, including Protocol for Nutritional Risk in Oncology (PRONTO) and the Malnutrition Screening Tool (MST).   

Clinicians are guided through evidence-based nutrition care processes, including screening, assessment, intervention, monitoring, and evaluation. The content highlights the role of adequate energy and protein intake, oral nutritional supplements (ONS), omega-3 fatty acids, and muscle-supportive nutritional strategies in improving treatment tolerance, recovery, and clinical outcomes.

The case concludes by illustrating how early identification of nutrition risk and prompt intervention can support surgical recovery and help maintain nutritional status and highlights the importance of nutrition as an essential component of oncology care.

Course Objectives:
  • Identify common nutritional challenges in patients with cancer, including malnutrition and muscle loss
  • Review expert guidelines for nutrition care, with a focus on nutrition screening
  • Describe the role of early and ongoing medical nutrition therapy (MNT) in supporting tolerance to cancer treatment, surgical recovery, and overall patient care
Key Takeaways:
  • Malnutrition is common and often underrecognized in patients with cancer highlighting the need for routine nutrition screening and assessment
  • Evidence suggests that incorporating nutrition support early in cancer therapy can improve nutritional status, intake, quality of life, and treatment tolerance, compared with delayed intervention.
  • Adequate pre and post-operative nutrition supports wound healing, preserves lean body mass, and may reduce complications and length of stay in surgical oncology patients.
  • Medical nutrition therapy should be integrated, individualized, and ongoing. Nutrition care is most effective when tailored to the patient’s diagnosis, treatment phase, and functional status, and delivered as a coordinated part of multidisciplinary cancer care

Related Questions:
  • Why is nutrition screening important for patients with cancer?
    Nutrition screening helps identify patients at risk for malnutrition before significant complications develop. Early identification supports timely intervention, which may improve nutritional status, treatment tolerance, recovery, and quality of life.
  • Can patients with obesity still be at high risk for malnutrition?
    Yes. A patient may have a BMI above 30 and still be at high nutritional risk if they experience significant unintentional weight loss, reduced oral intake, weakness, or loss of muscle mass.  Nutritional risk assessment should consider multiple factors beyond body weight alone.
  • What screening tools are commonly used in oncology nutrition care?
    Commonly used oncology nutrition screening tools include PRONTO (Protocol for Nutritional Risk in Oncology), the Malnutrition Screening Tool (MST), the Patient-Generated Subjective Global Assessment (PG-SGA), and Nutritional NRS-2002.
