Evaluation of response to gemcitabine plus cisplatin-based chemotherapy using positron emission computed tomography for metastatic bladder cancer

BACKGROUND The purpose of the present study was to examine retrospectively the contribution of 18Fluorodeoxyglucose positron emission tomography computed tomography(18FDG-PET/CT)to the evaluation of response to first-line gemcitabine plus cispla-tin-based chemotherapy in patients with metastatic bladder cancer.AIM To evaluate the response to Gemcitabine plus Cisplatin-based chemotherapy using 18FDG-PET/CT imaging in patients with metastatic bladder cancer.METHODS Between July 2007 and April 2019,79 patients underwent 18FDG-PET/CT imaging with the diagnosis of Metastatic Bladder Carcinoma(M-BCa).A total of 42 pa-tients(38 male,4 female)were included in the study,and all had been admi-nistered Gemcitabine plus Cisplatin-based chemotherapy.After completion of the therapy,the patients underwent a repeat 18FDG-PET/CT scan and the results were compared with the PET/CT findings before chemotherapy according to European Organisation for the Research and treatment of cancer criteria.Mean age was 66.1 years and standard deviation was 10.7 years(range:41–84 years).RESULTS Of the patients,seven(16.6%)were in complete remission,17(40.5%)were in partial remission,six(14.3%)had a stable disease,and 12(28.6%)had a pro-gressive disease.The overall response rate was 57.1 percent.CONCLUSION 18FDG-PET/CT can be considered as a successful imaging tool in evaluating response to first-line chemotherapy for metastatic bladder cancer.Anatomical and functional data obtained from PET/CT scans may be useful in the planning of secondline and thirdline chemotherapy.

Meta Analysis of Lentinan Injection plus Cisplatin in Treatment of Malignant Pleural Effusion

Objective To evaluate the efficacy and safety of lentinan injection plus cisplatin(LIC)in the treatment of malignant pleural effusion(MPE).Methods We searched the database of Cochrane Library,PubMed,EMBASE, ISI Web of Knowledge,Chinese Biomedical Literature Database,Chinese Scientific Journals Full-text Database, Chinese Journal Full-text,and Google Scholar,etc.,up to February 28th,2011 to identify randomized controlled trials(RCTs)about lentinan injection(LI)for MPE,evaluate the quality of the included studies,and analyze the data by Cochrane Collaboration’s RevMan5.0 software.Results Twenty-nine RCTs involving 1831 patients were included.Meta analysis results suggested that there were some differences when comparing LIC with control groups suffering from MPE,for LIC could improve the near-term curative effect and the quality of life to some extent. Besides,compared with chemotherapy alone,LI plus chemotherapy had an advantage in relieving adverse reactions, such as gastrointestinal reactions,myelosuppression,chest pain,and general malaise.Conclusion The current evidence indicates that LI may have adjuvant therapeutic effects for MPE.
