Is isolated anemia a good predictor of gastrointestinal (GI) malignancy?
Is isolated anemia a good predictor of gastrointestinal (GI) malignancy? Evidence-Based Answer: Isolated anemia in an adult increases the likelihood of an upper or lower GI malignancy, but it is not a strong predictor. Anemia has a sensitivity of 17%–37% and a specificity of 90%–92% for colorectal cancer, and a sensitivity of 13% and specificity of 95% for upper GI malignancy (SOR: B, meta-analyses of cohort studies).
