Objective:To investigate the high-risk factors for early postoperative recurrence in patients with colorectal cancer liver metastasis (CRLM).Methods:The clinical data of 156 CRLM patients who underwent hepatic metastasectomy at the Li Huili Hospital, Ningbo University from Jan 2015 to Dec 2021 was retrospectively analyzed.Results:Among 156 patients, the postoperative recurrence rate was 55.8% (87/156).There were significant differences ( P<0.05) in the primary tumor site, T stage, TBS score, preoperative concentrations of CEA, CA199 and CA125, the maximum diameter of metastatic tumors and the number of metastatic tumors between the group with recurrence in one year and the group without recurrence in one year. Multivariate analysis showed that preoperative CA125 concentration ( OR=1.021, P=0.020), CEA concentration ( OR=1.044, P=0.018), and tumor burden score ( OR=3.067, P=0.011) were high risk factors influencing early recurrence ( P<0.05). In the low TBS score group(≤4), among the 49 patients who underwent simultaneous resection, 13 suffered from recurrence within 1 year, with a recurrence rate of 26.5%. Meanwhile, among the 29 patients who underwent staged resection, 17 suffered from recurrence within 1 year, with a recurrence rate of 58.6% ( P<0.05). In the high TBS score group(>4), among the 51 patients who underwent simultaneous resection, 37 suffered from recurrence within 1 year, with a recurrence rate of 72.5%, while in the 27 patients who underwent staged resection, 20 suffered from recurrence within 1 year, with a recurrence rate of 74.1% ( P>0.05). Conclusions:Preoperative TBS score, preoperative CA125 concentration, and CEA concentration are high-risk factors for postoperative recurrence in patients with colorectal liver metastases, simultaneous resection in patients with a low TBS score can reduce the risk of recurrence within 1 year after surgery.

Objective:To investigate the effect of different primary sites of colorectal cancer on early recurrence after radical resection of metastatic tumor clinical risk score (CRS).Methods:The data of colorectal cancer liver metastasis (CRLM )surgically resected between Jan 2015 and Feb 2020 were retrospectively analyzed at Li Huili Hospital and Ningbo University People's Hospital. Risk factors leading to early recurrence after CRLM resection were analyzed by univariate analysis, and the significant results were then subjected to multifactorial analysis by COX regression model. Kaplan-Meire method was used to analyze the effect of primary site on disease-free survival at 1 year after CRLM resection in different CRS subgroups.Results:A total of 209 patients were included in the study, including 143 patients with primary tumors in the left colon and 66 in the right colon. One hundred and three (49.3%) patients with recurrence within 1 year.Univariate analysis showed that primary tumor site, neoadjuvant chemotherapy, and CRS were correlated with recurrence. Multivariate analysis showed that right colon cancer, poor efficacy of neoadjuvant therapy, and high risk of CRS were independent risk factors (all P<0.05). Patients with an overall low CRS risk group and low CRS after treatment, had a higher recurrence rate (all P<0.05) within 1 year when primary tumor located right colon. Conclusion:The location of the primary tumor in the right colon is an independent risk factor for recurrence within 1 year after radical surgery in patients with CRLM.

Objective To evaluate FIB-NLR,a combined neutrophil-lymphocyte ratio (NLR) and fibrinogen concentration (FIB) in predicting the prognosis of gastrointestinal stromal tumors (GIST).Methods Data of 79 GIST patients who underwent surgery from Jun 2010 to Dec 2014 were retrospectively analyzed.Patients were divided into 3 groups:NLR ＜ 2.30 and FIB ＜ 3.85 g/L were defined as group 0,NLR≥2.30 and FIB ＜3.85 g/L or NLR ＜2.30 and FIB≥3.85 g/L as group 1,NLR≥2.30 and FIB≥3.85 g/L as group 2.The clinicopathological features of the three groups and the 5-year recurrence-free survival rate after surgery were compared.Results FIB concentration and NLR were significantly correlated with NIH risk grade and tumor size in GIST patients (x2 =9.517,12.41 1,6.081,20.067,all P ＜ 0.05).FIB-NLR was closely related to tumor size,tumor risk and tumor mitosis (x2 =14.406,12.514,28.225,all P ＜ 0.05).Survival analysis showed that high FIB predicts lower 5-year recurrence-free survival rate,it was 87.4％ for group 0,60.8％ for group 1,21.1％ for group2,x2 =29.617,P＜0.000).Conclusion FIB-NLR independently predicts the prognosis of gastrointestinal stromal tumors.
