ABSTRACT
ObjectiveTo explore the difference in quality of life in patients with gastrointestinal cancer between those who knew cancer diagnosis and those who did not.Methods 130 patients with recently diagnosed gastrointestinal cancer in 4 general hospitals in Tangshan were interviewed. Patients were categorized into two groups:one group was those who knew their diagnosis(n=62) and the other group was those who did not ( n =68).The Chinese version of European Organization for Research and Treatment (EORTC) quality of life (QOL)questionnaire (QLQ-C30) was used.ResultsThe comparison of quality of life between patients who knew their diagnosis and those who did not indicated that the score of global quality of life and other functional scales including physical,emotional,role and cognitive functioning did not show significant difference(P ＞ 0.05 ).Compared with those who did not know cancer diagnosis,patients who were aware of diagnosis showed a significant lower degree of social functioning ( (45.8 ± 24.2 ) vs ( 73.0 ± 16.2 ) ),a significant higher degree of fatigue ( ( 55.8 ±26.2) vs (41.8 ±10.2) ) and financial difficulties ((38.2 ±35.1) vs (12.00 ±10.0) ) (P＜0.01).In multiple regression analysis,physical functioning and symptom of fatigue had statistically significant differences (P＜ 0.05 ).ConclusionThe knowledge of cancer diagnosis does not contribute to the quality of life in patients with gastrointestinal cancer.
ABSTRACT
Objective:To investigate the expressions of Mfn2(mitofusin 2) in non-small-cell lung cancer (NSCLC) tissues and non-cancerous lung tissues,and analyze its relationship with clinicopathological characteristics of lung carcinomas.Methods:The expressions of Mfn2 mRNA and protein in 92 cases of NSCLC tissues and 27 cases of non-cancerous lung tissues were detected by in situ hybridization and immunohistochemical methods. Results:The positive rates of Mfn2 mRNA and protein in pulmonary squamous cell carcinoma were higher than those in adenocarcinoma (83.33% and 89.58% vs 56.82% and 65.91%), respectively. The positive rates of Mfn2 mRNA and protein in NSCLC were higher than those in the non-cancerous lung tissues (25.93% and 29.63%) . The difference was statistically significant among the three groups (P0.05). The expression of Mfn2 mRNA was consistent with that of Mfn2 protein in NSCLC.Conclusion:Mfn2 was involved in the initiation and progression of lung cancer, and the expression of Mfn2 was related to the histological types of lung cancer and its differentiation degree.
ABSTRACT
Objective To investigate the expression of hyperplasia suppressor gene(HSG)/mitofusin 2 (Mfn2)and P21 WAF1 in non-small cell lung cancer(NSCLC).Methods The expression of(HSG/Mfn2)and P21 WAF1 was detected in 92 cases of NSCLC samples by immunohistochemistry(SP).Results The absorptance value of the expression of HSG/Mfn2 in squamous cell carcinoma,adenocarcinoma,and non-cancer tissue were 15.06±2.73,12.21±2.96 and 10.36±3.60,respectively(P<0.05),and they were associated with tumor differentiation.The absorptanee valtue of the expression of P21 WAF1 in squamous cell carcinoma,adenocarcinoma,and non-cancer tissue were 3.16±0.98,3.44±0.22,0.06±0.32.The expression of P21 WAF1 in squamous cell carcinoma and adenocarcinoma Was higher than that in non-cancer tissue(P<0.05),and was closely associated with tumor differ-entiation and lymph node metastasis.Conclusion HSG/Mfn2,P21WAF1 is closely related to the pathogenesis and development of lung cancer.There is positive correlation between the HSG/Mfn2 and P2l WAF1 in lung cancer.
