ABSTRACT
@#Objective To explore the association of pretreatment hyponatremia with clinicopathological and prognostic characteristics of non-small cell lung cancer (NSCLC) patients. Methods The PubMed, EMbase, Web of Science, VIP, CNKI and WanFang databases were searched from the inception to July 12, 2021 for relevant literatures. The quality of included studies was assessed by the Newcastle-Ottawa Scale (NOS) score. The relative risk (RR) and hazard ratio (HR) with 95% confidence interval (CI) were combined to assess the relationship between pretreatment hyponatremia and clinicopathological and prognostic characteristics. The prognostic indicators included the overall survival (OS) and progression-free survival (PFS). All statistical analysis was conducted by the STATA 15.0 software. Results A total of 10 high-quality studies (NOS score≥6 points) involving 10 045 patients were enrolled and all participants were from Asian or European regions. The pooled results demonstrated that male [RR=1.18, 95%CI (1.02, 1.36), P=0.026], non-adenocarcinoma [RR=0.86, 95%CI (0.81, 0.91), P<0.001] and TNM Ⅲ-Ⅳ stage [RR=1.17, 95%CI (1.12, 1.21), P<0.001] patients were more likely to experience hyponatremia. Besides, pretreatment hyponatremia was significantly related to worse OS [HR=1.83, 95%CI (1.53, 2.19), P<0.001] and PFS [HR=1.54, 95%CI (1.02, 2.34), P=0.040]. Pretreatment hyponatremia was a risk factor for poor prognosis of NSCLC patients. Conclusion Male, non-adenocarcinoma and advance stage NSCLC patients are more likely to experience hyponatremia. Meanwhile, the pretreatment sodium level can be applied as one of the prognostic evaluation indicators in NSCLC and patients with hyponatremia are more likely to have poor survival. However, more researches are still needed to verify above findings.
ABSTRACT
Objective To investigate the clinicopathological characteristics and independent risk factors of hepatocellular carcinoma (HCC) differentiation. Methods A total of 108 HCC patients who underwent operation and treatment were reviewed and classified into low differentiation group (n= 29, 26.85%), medium differentiation group (n=53, 49.07%) and high differentiation group (n=26, 24.07%) according to pathological diagnosis. The clinicopathological characteristics and the expression levels of Ki67 and P53 in each group were compared and analyzed. Logistic regression model was used to analyze the risk factors for low differentiation of HCC. Results The proportion of cirrhosis, the positive rate of P53 and Ki67 expression level in different degrees of HCC differentiation were statistically significant (P0.05). Multivariate logistic analysis showed that cirrhosis (OR=3.408), high expression of Ki67 (OR=11.113) and positive P53 (OR=9.711) were the main risk factors for poorly differentiated HCC. Conclusion There are differences in clinical characteristics and expressions of Ki67 and P53 in HCC patients with different degrees of differentiation. Logistic regression analysis can identify clinicopathological risk factors affecting the degree of differentiation of HCC, which can provide criterion support for accurate diagnosis and prognostic treatment.
ABSTRACT
Objective To analyze the clinicopathological characteristics and the prognostic survival factors of young patients who have undergone hepatectomy for primary hepatic carcinoma.Methods Clinicopathological da-ta and treatment outcomes in 79 young (≤40 years old)and 67 elderly (≥65 years old)patients who underwent hep-atectomy for primary hepatic carcinoma between 2008 and 2012 were retrospectively collected and compared using various parameters.Then the survival rate and prognostic factors of the younger patients were analyzed using Kap-lan-Meier and COX multivariate proportional hazards model.Results The positive rate of HBs-antigen and alpha-fetoprotein level were significantly higher in the younger patients than in the elderly patients (P0.05).The overall survival rate was similar between the two groups.COX multivariate proportional hazards model analysis showed that the independent prognostic factors of overall survival were pre-operative albumin level <3 5 g/L and maximum tumor diameter ≥5 cm.Conclusion Hepatectomy is a safe and feasible treatment for young and elderly patients with primary hepatic carcinoma.The independent prognostic factors of survival for young patients are pre-operative albumin level <3 5 g/L and the maximum tumor diameter ≥5 cm.
ABSTRACT
ObjectiveTo investigate the relationship between Dicer expression and clinicopathological characteristics and prognosis by detecting the expression of Dicer in hilar cholangiocarcinoma tissues and cells.MethodsThe expression of Dicer in tissues was detected using immunohistochemistry.Western blotting and RT-PCR were used to investigate Dicer expression in QBC939 and HIBEpic cells.The relationship between Dicer expression and clinicopathological characteristics was analyzed.A Kaplan-Maier analysis was performed to analyze the disease-free survival (DFS) and overall survival (OS) after radical surgical resection of hilar cholangiocarcinoma.ResultsWhen compared to control,Dicer was significantly down-regulated in hilar cholangiocarcinoma tissues (P＜0.05) and in QBC939 (P＜0.05).The expression of Dicer was higher in well differentiated adenocarcinoma than poorly and moderately differentiated tumours. Univariate analysis showed low expression of Dicer protein was significantly correlated with short disease-free survival and overall survival of patients with hilar cholangiocarcinoma after radical surgical resection (P＜0.01). Multivariate analysis revealed that the expression of Dicer was the most important factor for predicting prognosis after radical surgical resection of hilar cholangiocarcinoma (P＜0.05).ConclusionsDicer could be used as a prognostic marker for hilar cholangiocarcinoma.
