About this study

When possible, surgery to completely remove small intestinal neuroendocrine tumors (siNETs) is always recommended. However, in cases where the tumor has spread and cannot be cured completely, it is unclear whether a surgical removal of the primary tumor only is reasonable. In this situation, current guidelines from the European Neuroendocrine Tumor Society (ENETS) recommend surgery only for patients who have symptoms like intestinal blockage or bleeding, or are at risk of such complications. For patients without symptoms, it is still unclear whether removing the main tumor improves overall outcomes and prevents future problems. Studies evaluating this type of surgery on survival show conflicting results. These studies often do not separate patients with symptoms from those without, and they overlook other important factors like the amount of cancer in the liver and nearby tissues. Due to these uncertainties, the rarity of siNETs and many factors that can affect outcomes, like age, overall health, or other current treatments, conducting a high-quality study to answer this question is challenging. To address this, the present Europe-wide study is being planned. This study aims to determine if resecting the main tumor improves the 10-year overall survival and reduces risks like intestinal blockages or blood flow issues compared to no surgery in patients without symptoms. The study will also assess other outcomes, such as how long patients stay free from disease progression, th…
