ABSTRACT
Objective To evaluate curative effect and related prognosis factors of synchronous colorectal cancer with liver metastasis.Methods The clinicopathological and follow-up data of 47 patients undergoing surgical treatment with synchronous colorectal cancer with liver metastasis at Shanghai Jiaotong University Affiliated Sixth People's Hospital and Tongji University Affiliated Yangpu Hospital from Jun 2013 to Jan 2018 were retrospectively analyzed.Results All 47 patients were followed up and themedian followup time was 38 months (2-65 months),after simultaneous colorectal and hepatic neoplasm radical surgery,added in 41 patients by postoperative chemotherapy.There was no perioperative mortality and the postoperative complication rate was 34％.The 1-,3-,and 5-year overall-survival rates were 87％,53％,and 15％,respectively.The disease-free survival rates were 81％,43％,and 9％,respectively.Multivariate results showed tumor differentiation,serum CEA level and adjuvant chemotherapy are independent prognostic factors for patients with synchronous colorectal cancer liver metastasis (P ＜ 0.05).Conclusions Colorectal cancer with synchronous liver metastasis treated by simultaneous resection of colorectal cancer and liver metastases are the widerly adopted treatments.Long-term survival is closely related to the degree of primary neoplasm differentiation,serum CEA level at diagnosis,and postoperative adjuvant chemotherapy.
