Objective To compare the clinicopathological features of hilar cholangiocarcinoma (HCCA) and hilar benign diseases, and then explore the value of carbohydrate antigen 19-9 (CA19-9) and carcinoembryonic antigen (CEA) in the differential diagnosis between them. Methods Clinical data of 65 patients (54 patients with HCCA and 11 patients with hilar benign diseases) who were diagnosed as HCCA and received treatment from January 2011 to October 2015 in our hospital were retrospectively analyzed. Comparison of clinical data of HCCA patients and patients with hilar benign diseases in age, gender, disease duration, clinical manifestation, laboratory examination, and imaging examination was performed, and the receiver operating characteristic curve (ROC) was used to explore the value of CA19-9 and CEA in differential diagnosis between hilar benign diseases and HCCA. Results The age, levels of serum CA19-9, CEA, alanine aminotransferase (ALT), total bilirubin (BILT), and direct bilirubin (BILD) of HCCA group were significantly higher than that in benign group (P<0.05). However, the gender, disease duration, clinical manifestations (including jaundice, abdominal discomfort, fever, and weight loss), serum aspartate aminotransferase (AST), serum alkaline phosphatase (ALKP), and imaging findings (including hilar mass, intrahepatic bile duct dilatation, thickening of the bile duct wall, lymph node enlargement, vascular invasion, and gallbladder invasion) had no significant difference between the 2 groups (P>0.05). The ROC curve results showed that, when cut-off point for CA19-9 was 233.15 U/mL, the sensitivity was 56% and specificity was 91%; when cut-off point for CEA was 2.98 ng/mL, the sensitivity was 61% and specificity was 90%. Conclusions For the differential diagnosis between HCCA and hilar benign diseases, the elderly patients with high levels of serum transaminase and bilirubin were more likely to be malignant. It is more likely to be malignant when the serum CA19-9>233.15 U/mL or CEA>2.98 ng/mL.
ObjectiveTo explore the application value of the combined detection of CA19-9, CA72-4, carcinoembryonic antigen (CEA), serum pepsinogen Ⅰ(PGⅠ), serum pepsinogen Ⅱ(PGⅡ), ratio of PGⅠ and PGⅡ (PGR), and gastrin-17 (G17) in the diagnosis of gastric cancer.MethodsOne hundred cases of gastric cancer admitted to the Joint Logistic Support Force 940 Hospital of the People’s Liberation Army from January 2016 to August 2018 were respectively collected as the observation group, 110 cases of benign gastric lesions as the control group during the same period, the levels of serum CA19-9, CA72-4, CEA, PGⅠ, PGⅡ, PGR, and G17 were tested among patients in the two groups, the diagnostic value of single and combined detection (included CA19-9, CA72-4, CEA, PGⅠ, PGⅡ, PGR, and G17) were explored.ResultsThe levels of CA19-9, CA72-4, CEA, and G17 in the observation group were higher than those of the control group (P<0.05), the levels of PGⅠ and PGR were lower than those of the control group (P<0.05). The positive detection rates of CA19-9, CA72-4, CEA, G17, PGⅠ, PGR, and combined detection in the observation group were all higher than those of the control group (P<0.05). The sensitivity and accuracy of the combined detection in the diagnosis of gastric cancer were higher than that of single serum index (P<0.05). The levels of serum CA19-9, CA72-4, CEA, and G17 in the patients of Ⅲ+Ⅳ period, low and moderate degree of differentiation, the tumor diameter was larger than five centimeters, signet-ring cell carcinoma, and distance metastasis of gastric cancer patients were on the high side compared with Ⅰ+Ⅱ period, high differentiation, the tumor diameter was less than or equal to five centimeters, glandular cancer, and no distance metastasis of gastric cancer patients, as well as the levels of serum PGⅠ and PGR on the low side (P<0.05).ConclusionThe combined detection of CA19-9, CA72-4, CEA, PGⅠ, PGⅡ, PGR, and G17 can effectively improve the diagnose rate of gastric cancer, and they are closely related to the pathological characteristics of gastriccancer patients.
ObjectiveTo explore value of preoperative neutrophil-to-lymphocyte ratio (NLR) combined with carbohydrate antigen 19-9 (CA19-9) in evaluating prognosis for patients with pancreatic head carcinoma.MethodsThe clinical data of patients with pancreatic head carcinoma underwent radical pancreaticoduodenectomy in the Lanzhou University Second Hospital from February 2011 to August 2017 were retrospectively analyzed. The preoperative serum albumin (ALB), CA19-9, NLR, carcino-embryonic antigen (CEA), alpha-fetoprotein (AFP), N stage, tumor differentiated degree, and other indicators were recorded and the patient’s overall survival was recorded. Linear correlation analysis was used to examine the association of NLR with serum CA19-9. The receiver operating characteristic (ROC) curve was used to calculate the cutoff values of NLR and CA19-9 corresponding to the overall survival rate of 2-year. Kaplan-Meier method was used for survival analysis. Cox proportional hazards regression model was used to evaluate the prognostic value of preoperative CA19-9 and NLR.Results① A total of 121 patients were enrolled in this study. There was no significant correlation between the preoperative serum CA19-9 and NLR (r=0.100 05, P=0.272 9). ② Multivariate analysis showed that higher NLR, higher CA19-9 level, higher N stage, and lower tumor differentiation were the risk factors for overall survival of pancreatic head carcinoma (P<0.05). ③ The cutoff values of CA19-9 and NLR in evaluating the 2-year overall survival rate were 123.3 U/mL and 2.34 respectively by the ROC curve analysis, the area under ROC curve of CA19-9, NLR, and CA19-9 combined with NLR were 0.763, 0.686, and 0.823, respectively. ④ The proportions of patients with CEA≥5 μg/L and ≥N1 stage were higher in the patients with CA19-9≥123.3 U/mL as compared with patients with CA19-9<123.3 U/mL (P<0.05); The proportions of patients with preoperative serum ALB level <35 g/L and CEA≥5 μg/L, ≥N1 stage, and poor differentiation were higher in the patients with NLR≥2.34 as compared with the patients with NLR<2.34 (P<0.05). ⑤ Kaplan-Meier survival analysis showed that patients with CA19-9≥123.3 U/mL and NLR≥2.34 had worse overall survival than those patients with CA19-9<123.3 U/mL and NLR<2.34 (HR=3.599, P<0.01; HR=2.506, P<0.01). The patients with CA19-9≥123.3 U/mL and NLR≥2.34 (n=42), CA19-9≥123.3 U/mL or NLR≥2.34 (n=48), CA19-9<123.3 U/mL and NLR<2.34 (n=31) had better overall survival in turn (overall and between groups, all P<0.01).ConclusionPreoperative serum CA19-9 combined with NLR has an important value in evaluating prognosis for patients with pancreatic head carcinoma.
