How strong is the evidence supporting surgery for patients with metastatic neuroendocrine tumors(NETs)?This is the chief question from ***’comprehensive and balanced literature analysis on the surgical treatment of metastatic pancreatic NETs(1).No matter how many non-randomized studies demonstrate a survival advantage for patients undergoing cytoreductive hepatic surgery or resection of the primary pancreatic tumor,the methodological biases remain constant(2-9).Patients undergoing surgery tend to be younger and healthier,and their tumors tend to be lower grade,less aggressive,and fewer in number than patients undergoing other systemic or liver-directed *** other words,the survival advantage begins when the patient is selected as a surgical candidate and before the scalpel even touches the *** multivariate analyses can control for some confounding variables,it is impossible to control for *** a simple concept such as tumor burden is challenging to standardize:a patient with a few large tumors confined to a single hepatic lobe may have a vastly different prognosis than a patient with a similar burden of miliary tumors scattered throughout the liver(2).
