ABSTRACT
Objective To explore the efficiency of postoperative individualized chemotherapy based on genetic testing results for non-small cell lung cancer (NSCLC). Methods Fifty-six NSCLC patients at stageⅡorⅢA who accepted video-assisted thoracic operation were divided into two groups:the individualized chemotherapy group (n=26) and non individual?ized chemotherapy group (n=30). The fresh lung tumor tissue of individualized chemotherapy group was tested target gene,in?cluding excision repair cross complementing 1 (ERCC1),ribonucleotide reductase subunit M1 (RRM1),β-tubulinⅢ,thymi?dylate synthase(TS),epidermal growth factor receptor (EGFR) and breast cancer gene 1 (BRCA1). The theraputic plan was based on genetic testing results in individualized chemotherapy group, and the non individualized chemotherapy group re?ceiving gemcitabine plus cisplatin. The 1-year disease free survival (DFS), 2-year disease free survival (DFS), the progres?sion-free survival (PFS) and the overall survival (OS) were compared between two groups. Results The 2-year DFS (57.69%), PFS (22.1 ± 5.0 months) and OS (24.1 ± 3.2 months) were significantly higher in the individualized chemotherapy group than those of non individualized chemotherapy group (respectively 30.00%, 18.9 ± 6.2 months, 21.9 ± 4.3 months, P<0.05). There was no significant difference in 1-year DFS between two groups (88.46%vs 83.33%, P<0.05). Conclusion The individualized chemotherapy based on genetic testing results can enhance the 2-year DFS, PFS, OS and the efficiency of postoperative adjuvant chemotherapy for NSCLC.
ABSTRACT
Objective To investigate the effects of Chinese herbal medication combined with nutrition intervention on perioperative nutrition in patients with colon carcinoma.Methods Ninety-six patients with colon carcinoma were divided according to their odd or even number into the control group and the intervention group.The former were given routine nutrition and the latter Chinese herbal medication combined with nutrition intervention.Then the mini-nutritional assessment(MNA)was used to assess the changes before and after operation and the complications.Results The intervention group was significantly better than the control one in terms of all nutrition factors but hematoglobin(P<0.05).The incidences of complication and dystrophy in the intervention group were lower than in control group(P<0.05).Conclusion The application of Chinese herbal medication combined with nursing intervention is important for the improvement of their nutrition and the reduction of postoperative complications.
ABSTRACT
Background and purpose:The prognosis in patients with early breast cancer(EBC) was poorly defined by clinical and histopathological features.There were more than 200 genes that might be correlated with development,progression,recurrence and prognosis of breast cancer in the published literature.This study evaluated the prognosis of patients with EBC at molecule level according to the protein expressions of 16 selecting genes(HER2,ER,PR,BCL2,Ki-67,BMYB,Cyclin B1,STK15,MMP11,BAG1,NM23,PTEN,P53,P27,VEGF,PCN A).Methods:The immunohistochemical method was used to detect the protein expressions of these genes in 76 patients with EBC and the statistical analysis was performed by COX proportional hazards model.Results:COX proportional hazard model revealed that BCL2,VEGF and STK15 were independent prognostic factors for patients with EBC.A formula of PI was set up according the three genes.The predictive outcomes with PI were compared with the actual follow-up outcomes in 48 patients with EBC.As a result,the predictive accuracy of good and bad prognosis was 86.67% and 91.67%,respectively.Conclusion:A formula of PI derived from protein expressions of the 16 genes correlated with breast cancer was ultimately set up and might be used to predict the outcomes of the patients with EBC.
ABSTRACT
Objective To search for the molecular figngerprint of ascaris lumbricoides in intrahepatic stones. Methods In 56 cases deoxyribonucleic acid (DNA) was exstracted from intrahepatic stones and surgically obtained bile duct tissues, stool and sercum examinations were performed. Based on the sequence and designed primers of ITS-2 of ascaris lumbricoides, polymerase chain reaction ( PCR) was performed. Results There were 12 positive results in 56 (21.4% ) cases of intrahepatic stones. Positive reaction appeared on the examinations of the stool on ascaris lumbricoides and the blood serum among 12 cases. Conclusions Ascaris lumbricoides DNA was found in human of intrahepatic stones, indicating that ascaris lumbricoides infection may play a role in the formation of intrahepatic stones.
