Small intestine neuroendocrine tumor (SI-NET), the most common cancer of the small bowel, often displays a curious multifocal phenotype with several tumors clustered together in a limited intestinal segment.

The evolutionary trajectories that underlie multifocal SI-NET lesions could provide insight into the...
