A second study that recruited 198 surgically resected pancreatic cysts reported that a cutoff value of 109.9 ng/mL had a sensitivity and specificity of 81% and 98%, respectively, for diagnosing a mucinous cyst [23], further addressing the conflicting results regarding the diagnostic performance of CEA > 192 ng/mL for mucinous cysts. The gene discussed is CEACAM5; the disease is Pancreatic cysts.
