During active cancer treatment, which combination constitutes red flags for weight loss?

• A. Unintentional weight loss of 5% with MST score 1.
• B. MST score of 2 or higher, unintentional weight loss of 2% or more.
• C. Weight gain of 2% with MST score 0.
• D. Unintentional weight loss of 1% with MST score 0.

Answer: (B)

The central idea is that red flags for weight loss in active cancer treatment come from a combination of malnutrition risk and actual unintentional weight loss. The Malnutrition Screening Tool (MST) scores how risky malnutrition is, and measuring unintentional weight loss shows how much weight has been lost. When someone has an MST score of 2 or higher, that signals a high risk of malnutrition. If they also have unintentional weight loss of 2% or more, that combination strongly suggests clinically significant weight loss that needs attention now. This pairing flags a level of concern that should prompt a nutrition assessment and possible intervention. In the other scenarios, the risk signal isn’t as strong. If the MST score is 0 or 1, even with weight loss present, the malnutrition risk isn’t high enough by itself to constitute a red flag in this framework. Weight gain or minimal weight loss (like 1%) without evidence of malnutrition risk doesn’t indicate a concerning weight-loss pattern during treatment, and thus isn’t flagged as urgent in this context.
