ABSTRACT
OBJECTIVE:To investigate the effect and clinical significance of radiotherapy on the expression of multidrug resistance-associated protein(MRP) in advanced cervical cancer.METHODS:The immunohistochemistry method was applied to detect the expression of lung resistance protein(LRRP),glutathione-S-transferases-?(GST-?),thymidylate synthetase(TS) and type Ⅱ topoisomerase(TopoⅡ) in 23 patients with advanced cervical cancer before radiotherapy and after receiving 30 Gy dose radiation.RESULTS:The positive expression rates of LRRP,GST-?,TS and TopoⅡ before radiotherapy were 47.8%,56.5%,30.4% and 60.9%,respectively.The positive expression rates of LRRP,GST-? and TS in patients after 30 Gy dose radiation were 69.6%,73.9% and 73.9%,respectively,which were signficantly higher as compared before radiotherapy(P
ABSTRACT
OBJECTIVE:To observe the clinic efficacy and safety of FOLFIRI as a second line treatment for patients with advanced colorectal cancer.METHODS:Twenty-eight patients with advanced colorectal cancer whose disease progressed after first treatment with FOLFOX4 were included to receive the second line treatment with FOLFIRI regimen.RESULTS:Of the total 28 cases,0 had complete response,6 partial response,16 stable disease,6 progressive disease,and the responsive rate was 21.4%.The majority of adverse reaction was nausea,vomiting,leucopenia and tardive diarrhea.CONCLUSION:As a second line therapy,FOLFIRI has a confirmed therapeutic response and tolerable toxicity in patients with advanced colorectal cancer.
ABSTRACT
OBJECTIVE:To evaluate the radiosensitization effect of docetaxel versus sodium glyci-didazole.METHODS:A total of 105 patients with intermediate or advanced stage nasopharyngeal carcinoma were randomly assigned to receive docetaxel 40 mg once a week plus radiotherapy or sodium glycididazole 1 000 mg three times a week(Monday,Wednesday and Friday) plus radiotherapy for a total of 7 weeks,or radiotherapy only(control group).RESULTS:There were significant differences between docetaxel group or sodium glycididazole group and control group in sensitization efficiency and radiation dose on tumor regression(P0.05).CON-CLUSION:Lower dose docetaxel is better than sodium glycididazole in radiosensitization efficiency for advanced nasopharyngeal carcinoma,especially in controlling the metastasis,yet it has minimal side effect.
