Fig. 3From: Pathologic response after preoperative therapy predicts prognosis of Chinese colorectal cancer patients with liver metastasesPathologic response of colorectal cancer patients with liver metastasis according to potential factors. Metastases were classified according to tumor size (a), duration of preoperative chemotherapy (b), CEA variation (c), primary tumor site (d), and preoperative treatment (e). The distribution (%) of partial histologic response (TRG3) and major histologic response (TRG1–2) statuses was reported within each category of tumor size, duration of preoperative chemotherapy, CEA variation, primary tumor site and preoperative treatment. For preoperative treatment, the comparisons were conducted between every two regimens. Only significant pairwise comparisons were noted (P < 0.05).
