Objective To evaluate the value of neutrophil-lymphocyte ratio (NLR) in the chemotherapy curative effect and prognosis of patients with advanced colorectal cancer (CRC). Methods Retrospective collection of clinical data from 50 patients with advanced unresectable colorectal cancer who received oxaliplatin-based standard first-line chemotherapy between January 2016 and April 2019. Chemotherapy curative effect was evaluated following 2 chemotherapy cycles. Calculation of neutrophil to lymphocyte ratio (NLR) based on pre-chemotherapy hematology data. The receiver operating characteristic curve was used to determine the optimal cutoff value of NLR,according to patients who were divided into groups of high NLR(NLR≥3.785)and low NLR(NLR≥3.785).The differences between high and low NLR and clinicopathological features, efficacy of chemotherapy, progression-free survival (PFS), and total survival (OS) were compared. COX regression analysis mode was used to analysis of factors affecting PFS and OS in patients with advanced colorectal cancer. Results The differences in tumor differentiation (P=0.030), ECOG score (P=0.003), CEA (P=0.011), CA19-9 (P=0.047) in the high and low NLR groups were statistically significant. The differences in chemotherapy between the two groups was statistically significant (P<0.001), and the high NLR group was less effective. The median PFS of the high and low NLR groups were 3.44 months and 12.84 months, respectively, and the difference was statistically significant (χ²=39.730, P<0.001). The median OS of the high and low NLR groups was 7.59 months and 22.32 months, respectively, and the difference was statistically significant (χ²=40.505, P<0.001). Cox regression analysis suggested that NLR levels and CEA levels were independent prognostic factors for PFS and OS(P＜0.05). Conclusion High-level NLR is associated with poor chemotherapy response and poor prognosis in patients with advanced colorectal cancer, and was used as an indicator of chemotherapy efficacy and prognosis.

Objective To detect the expression of peripheral blood circulating tumor cells CTC in patients with primary liver cancer and to explore the dynamic changes of CTC and its predictive effect on postoperative recurrence and metastasis of primary cancer. Methods The number of CTC in peripheral blood was measured in 134 patients with primary liver cancer and 72 patients with benign liver disease, the expression of AFP was detected, and the correlation between CTC and AFP was analyzed. Then 86 patients with primary liver cancer were selected from 134 patients with primary liver cancer who underwent radical hepatectomy. The values of CTC and AFP in evaluating recurrence and metastasis of primary liver cancer before and after operation were analyzed by CTC and AFP, in peripheral blood of these 86 patients. Results The positive rates of CTC in peripheral blood of patients with primary liver cancer were higher than that of patients with benign liver disease(P< 0.05). The levels of CTC in patients with primary liver cancer were related to AFP level, lymph node metastasis and the number of tumor nodules, but not to age, sex, tumor diameter, differentiation degree, liver cirrhosis and TNM stage. The survival analysis of CTC and AFP in patients with primary liver cancer showed that the early recurrence and metastasis of primary liver cancer after radical resection were closely related to the positive rate of CTC and AFP, and the positive rate of CTC was more effective than that of AFP positive in the diagnosis of recurrence and metastasis after operation, and the combination of the two had the highest predictive value for recurrence and metastasis. Conclusion CTC may be used as a better index to monitor postoperative recurrence and metastasis of primary liver cancer than traditional tumor markers. The combined detection prediction value of tumor markers is higher.
