ABSTRACT
Objective:To investigate the effect of pidotimod in reducing pulmonary infection in patients with lung cancer undergoing chemotherapy.Methods:One hundred and twenty patients with lung cancer in the Fifth People′s Hospital of Dalian City from July 2017 to July 2018 were selected. The patients were divided into control group and pidotimod group by random digits table method with 60 cases each. The patients were treated with standard two drugs chemotherapy containing platinum drug according to the pathological type, and the patients in pidotimod group were combined with pidotimod. The number of pulmonary infections during chemotherapy, number of completed scheduled chemotherapy and adverse reaction were observed. The correlation between pulmonary infection and pidotimod was analyzed by multivariate orderly Logistic regression.Results:The incidence of pulmonary infection in pidotimod group was significantly lower than that in control group: 18.33% (11/60) vs. 40.00% (24/60), and there was statistical difference ( χ2 = 6.845, P<0.01). The rate of completed scheduled chemotherapy in pidotimod group was significantly higher than that in control group: 55.00% (33/60) vs. 36.67% (22/60), and there was statistical difference ( χ2 = 4.062, P<0.05). Multivariate orderly Logistic regression analysis result showed that pidotimod could reduce the risk of pulmonary infection ( OR = 0.210, 95% CI 0.072 to 0.606, P = 0.004), and help to complete the scheduled chemotherapy ( OR = 2.323, 95% CI 1.080 to 5.003, P = 0.031). In pidotimod group, no obvious adverse reaction related to pidotimod application was detected, and chemotherapy was not affected. Conclusions:Application of pidotimod can reduce the chance of pulmonary infection in patients with lung cancer undergoing chemotherapy and help patients complete scheduled chemotherapy.
ABSTRACT
Objective@#To analyze the expression of c-MET and its prognostic correlation in patients with lung adenocarcinoma.@*Methods@#The clinical data and pathological specimen of patients with lung adenocarcinoma in Dalian 5th People′s Hospital from January 2006 to December 2011 were retrospectively analyzed. The expression difference of c-MET between lung adenocarcinoma tissue and normal adjacent tissues was compared. The correlation of c-MET with the pathology and clinical factors was also analyzed.@*Results@#A total of 82 patients were retrospective analyzed, including 82 pathological specimens of lung adenocarcinoma and 45 specimens of normal adjacent tissues. Among 53 patients with stage Ⅰ-Ⅱ lung adenocarcinoma, 31 cases had low expression of c-MET and 22 cases had high expression of c-MET. Among 29 patients with stage Ⅲ lung adenocarcinoma, 10 cases had low expression of c-MET and 19 cases had high expression of c-MET. There was a correlation between TNM stage and c-MET positive expression in lung adenocarcinoma (P=0.037). The positive expression rate of c-MET was not significantly correlated with age, sex and differentiation degree (P > 0.05). Among 82 cases of lung adenocarcinoma, 39 cases had low expression of c-MET and 43 cases had high expression of c-MET; 45 cases of para-carcinoma tissuehad low expression of c-MET. The positive expression rate of c-MET in lung adenocarcinoma tissues was significantly higher than that in para-carcinoma tissue (P < 0.01). Kaplan-Meier survival curve analysis showed that the median disease-free survival was 41.5 months in c-MET high-expression group and 55.3 months in low-expression group. The expression level of c-MET was closely related to disease-free survival in lung adenocarcinoma patients (P < 0.05).@*Conclusions@#The expression of c-MET is significantly increased in patients with lung adenocarcinoma. The expression level has relevance with TNM staging and prognosis.
