R0 resection

An R0 resection is a surgical procedure where a cancer tumor is completely removed, along with a margin of healthy tissue around it. This approach ensures no cancer cells are left behind at the edges of the removed tissue, which is confirmed through careful examination. Achieving an R0 resection is important because it reduces the chance of cancer returning and indicates that the removal was thorough. It’s considered a successful outcome in cancer surgeries, aiming for no residual tumor remaining at the surgical margins.
