ABSTRACT
Objective To evaluate the clinical curative effect of multiple interventional techniques with skilled manipulation in treating common bile duct stones. Methods The clinical data of 36 patients with common bile duct stones, who were treated with percutaneous transhepatic puncture of intrahepatic bile duct and multiple interventional techniques, were retrospectively analyzed. Before operation, according to CT or MRI findings the optimal puncture path was selected to perform cholangiography so as to reconfirm the position, number and size of the stones. Depending on the size of the stone, the corresponding sized lithotripsy basket and balloon were selected. The duodenal papilla was dilated by balloon, and the stone was pushed into the duodenum with a balloon. After complete removal of stones, the internal and external biliary drainage tubes were routinely implanted and remained there for two weeks. Results The operation was successfully accomplished in 35 patients, the success rate was 97.2％. Successful removal of stones with single procedure was accomplished in 32 patients, and in 3 patients the complete removal of stones was achieved by secondary procedure. No serious complications were observed during the operation. Early postoperative complications included hyperamylasemia (n=2), bile peritonitis (n=2), small amount of bloody bile (n=3) . No biliary perforation occurred. Conclusion In treating common bile duct stones, the combination use of multiple interventional techniques with skilled manipulation has high success rate, low risk and less complications, therefore, it is an effective therapeutic method
ABSTRACT
Objective To evaluate the efficacy and adverse reactions of platinum-based combined chemotherapeutical regimens in treating relapsed or refractory non-Hodgkin lymphoma(NHL).Methods The clinical data of 68 patients with relapsed or refractory NHL treated with platinum-based combined chemotherapeutical regimens in the Affiliated Tumor Hospital of Guangxi Medical University from January 2008 to December 2014 were retrospectively analyzed.The curative effect of related regimens,adverse reactions and related influence factors were analyzed.Results Sixty-eight cases received 283 cycles of chemotherapy.In all cases,11 cases(16.18 ％) achieved the complete response(CR),31 cases(45.59 ％) achieved the partial response(PR),the overall response rate(ORR) was 61.76％;the median progression-free survival(PFS) was 6.51 months(95％CI:4.97-8.04 months).ORR and PFS in the cases of stage Ⅱ-Ⅲ,IPI score 0-2 and receiving only one chemotherapeutical regimen were superior to those in the cases of corresponding subgroup(P＜0.05);ORR and PFS had no statistical difference between the B cells lymphoma and Tcells lymphoma(P＞0.05).The medion PFS in the combined R group was 11.16 months,which was longer than 5.84 months in the non-combined R group(P =0.004).The major adverse events (stage Ⅱ-Ⅲ) included leukopenia (41.18 ％),thrombocytopenia (27.94％),hemoglobin decrease(11.76％),vomiting(8.82％) and diarrhea(1.47％).Conclusion The platinum-based combined chemotherapeutical regimens are effective with good safety in the treatment of relapsed or refractory NHL.
ABSTRACT
Objective:To evaluate efficacy and safety of multiple-dose tropisetron plus dexamethasone (DXM) versus palonosetron plus DXM for chemotherapy-induced nausea and vomiting. (CINV) in patients received multiple day-based highly emetogenic chemotherapy. Methods:Cancer patients who were receiving multiday-based highly emetogenic chemotherapy were randomly assigned to AB or BA groups. A randomized, cross self-control ed method was applied. Patients in AB group received palonosetron (0.25 mg) 30 min before chemotherapy on day 1 and 3 or additional day 5 in the first cycle;and with tropisetron (5 mg) 30 min before chemotherapy on day 1, 2, and 3, or sup-plementary days (day 4 and 5) in the second cycle. Patients in BA group were treated with tropisetron in the first cycle and with palonosetron in the second cycle. Tropisetron and palonosetron were administered with DXM (10 mg) on day 1, followed by additional doses (5 mg) on days 2 to 5. Palonosetron group comprised patients in the AB group in the first cycle and BA group in the second cycle, whereas tropisetron group included patients in the AB group in the second cycle and BA group in the first cycle. Efficacy and safety of tropisetron versus palonosetron in preventing CINV were evaluated. Results:Ninety-one patients were included in analyses. At day 3, 4, and 5, incidence rates of nausea in the palonosetron group reached 28.6%, 30.8%, and 24.2%, respectively, and those of the tropisetron group totaled 42.8%, 47.3%, and 39.6%, respectively (P<0.05). At day 4, 5, and 6, incidence rates of vomiting in the palonosetron group measured 28.6%, 18.7%, and 5.5%, respectively, and those of the tropisetron group reached 42.9%, 34.1%, and 14.3%, respectively (P<0.05). From day 4 to day 5, day 6 to day 7, and day 1 to day 7, the palonosetron group yielded significantly lower incidence rates of nausea and vomiting than tropisetron group (P<0.05). Rate of rescue treatment in the palonosetron group was lower than that in tropisetron group (13.2%vs. 24.2%, P=0.057). No statistical difference in toxicities was observed between the two groups. Conclusion:Palonosetron plus DXM features better efficacy than that of tropisetron plus DXM against delayed CINV induced by multiple day-based highly emetogenic chemotherapy, which was well tolerated in the two treatments.
