RESUMO
Objective:To compare the clinical efficacy and pharmacoeconomic evaluation of bevacizumab or cetuximab combined with chemotherapy in the treatment of advanced colorectal cancer.Methods:The clinical data of 68 patients with advanced colorectal cancer from January 2018 to December 2020 in Baotou Tumor Hospital were retrospectively analyzed. Among them, 40 patients with treated with bevacizumab combined with chemotherapy (bevacizumab group), 28 patients were treated with cetuximab combined with chemotherapy (cetuximab group), and the chemotherapy of two group was FOLFOX/FOLFIRI program. The short-term clinical efficacy, adverse reactions and pharmacoeconomic evaluation result were compared between two groups.Results:There were no statistical differences in effective rate and disease control rate between bevacizumab group and cetuximab group: 30.00% (12/40) vs. 28.57% (8/28) and 67.5% (27/40) vs. 60.71% (17/28), P>0.05. The incidence of Ⅲ to Ⅳ grade erythra in bevacizumab group was significantly lower than that in cetuximab group: 2.50% (1/40) vs. 71.43% (20/28), and there was statistical difference ( P<0.01); there were no statistical differences in the incidences of Ⅲ to Ⅳ grade bone marrow suppression, nausea vomiting, hepatic functional lesion and diarrhea between two groups ( P>0.05). The pharmacoeconomic evaluation result showed that the cost of monoclonal antibody and total cost in bevacizumab group were significantly lower than those in cetuximab group: (9 009 ± 1 500) yuan vs. (27 840 ± 2 202) yuan and (11 242 ± 1 731) yuan vs. (29 867 ± 3 002) yuan, and there were statistical differences ( P<0.01); the cost-effectiveness ratio in bevacizumab group was 37 473.3, and it in cetuximab group was 104 430.1, the incremental cost-effectiveness ratio of two programs was 11 640.6. Conclusions:In the treatment of advanced colorectal cancer, the efficacy of bevacizumab combined with chemotherapy is similar to that of cetuximab combined with chemotherapy, but bevacizumab combined with chemotherapy has lower costs and fewer adverse reactions, so bevacizumab is more economical and applicable.
RESUMO
Objective To investigate the cognition of colorectal cancer-related knowledge and influencing factors of patients with middle- and advanced-stage colorectal cancer in ethnic minority areas of Inner Mongolia. Methods According to the national population and the prevalence of colorectal cancer, 277 patients with colorectal cancer were selected by stratified and random sampling in Inner Mongolia. The patients were surveyed in Baotou, Chifeng, Bayannaoer, and other hospitals. The questionnaire included patients' basic information, cognition of colorectal cancer risk factors and screening knowledge, screening information, etc. Results Before suffering from the disease, the patients' knowledge of colorectal cancer (risk factors, early screening knowledge, treatment methods) was low. About 54.9% of patients were unaware of high risk factors for colorectal cancer, 75.8% of patients did not understand the knowledge of early screening of colorectal cancer, and 37.5% of patients did not underst and the treatment of colorectal cancer. The main influencing factors of colorectal cancer cognition were education level and occupation. Patients who work in institutions and enterprises and with higher education level had better cognition. Conclusion Patients with middle- and advanced-stage colorectal cancer in Inner Mongolia have poor knowledge and awareness of risk factors and screening of colorectal cancer before diagnosis. Education level and occupation are factors influencing colorectal cancer cognition, therefore, people with low knowledge rate of colorectal cancer and low education level as well as unemployed laid-off people should be given priority intervention.
RESUMO
Objective To determine the role of serum procalcitonin(PCT)and C-reactive protein (CRP)in predicting spontaneous bacterial peritonitis(SBP)in patients with liver cirrhosis combined with ascites. Methods Ninety-eight patients with liver cirrhosis combined with ascites were enrolled, including 48 cases with SBP(SBP group)and 50 cases without SBP(non-SBP group).The levels of serum PCT and CRP were compared between 2 groups.The receiver operating characteristic(ROC)curves were used to evaluate the diagnostic SBP value of PCT and CRP levels in patients with liver cirrhosis combined with ascites.Results The serum PCT and CRP levels in SBP group were significantly higher than those in non-SBP group:3.90(6.95)μg/L vs.0.50(0.43)μg/L and 20.80(11.27)mg/L vs.10.87(6.22)mg/L, and there were statistical differences(P<0.01).The ROC cures results showed that the areas under the curve of serum PCT and CRP levels were 0.924(95% CI 0.860-0.987)and 0.852(95% CI 0.777-0.926), and the optimal cut-off of predicting SBP in patients with liver cirrhosis combined with ascites were 0.81 μg/L and 13.89 mg/L. The sensitivity was 91.7% and 85.4%, and the specificity was 80.0%and 70.0% respectively.The mortality in SBP group was significant higher than that in non-SBP group:20.83%(10/48)vs.6.00%(3/50),and there was statistical difference(P<0.05).In SBP group,the serum PCT and CRP levels in death patients were significant higher than those in survival patients: 13.00 (10.90) μg/L vs. 2.50 (5.30) μg/L and 35.40 (31.22) mg/L vs. 18.05(10.15) mg/L, and there were statistical differences(P<0.01 or<0.05).Conclusions The increase of serum PCT and CRP levels can be used as an important diagnostic index for SBP in patients with liver cirrhosis combined with ascites, and has predictive value for prognosis.
