RGA, right gastric artery; A2, the superior lateral subsegmental artery of the left hepatic artery; A3, the inferior lateral subsegmental artery of the left hepatic artery; A8, the anterior superior subsegmental artery of the right hepatic artery; A7, the posterior superior subsegmental artery of the right hepatic artery; A6, the posterior inferior subsegmental artery of the right hepatic artery; CR, complete response
*CR rates were evaluated in 29 tumors in the Spiegel lobe, 32 in the paracaval portion, and 10 in the caudate process
