Purpose:To compare the therapeutic effect and significance of different drugs poured in intravesical instillation for superficial biadder tumor after transurethral resection of bladder tumor.Methods:117 patients of superficial bladder cancer after transurethral vesection were divided into four groups. Ballistocardiogram group(n=26);Mitomycin C group (n=27);adriamycin group (n=27);hydroxycamptothecin group(n=37).Results:The tumor recurrent rate in Ballistocardiogram group, mitomycin groups, adriamycin group, hydroxycamptothecin group were 30.77%,40.74% 33.33%,24.32% respectively. The tumor recurrent rate differed significantly between the hydroxycamptothecin group and the mitomycin and Adriamycin groups.Conclusions:Intravesical instillation of hydroxycamptothecin for patients with superficial bladder tumor after transurethral resection of bladder tumour could decrease tumor recurrent rate, prolong the tumor-free survival period.

Objectives:To study the effects of parenteral nutrition in postoperative gastrointestinal carcinoma during perichemotheraputic period. Methods:80 patients with gastro intestinal carcinoma were divided into two groups.One group patients received chemotherapy and the other group patients received both chemotherapy and parenteral nutrition during first chemotharapy period.Then breatments changes each other between groups. Results:The nutritional condition,the concentrations of immunoglobumins and WBC in chemotherapy and parenteral nutrition group were significantly improved than those in chemotherapy group. Conclusions:It is helpful for the patients with gastrointestinal carcinoma to receive parenteral nutrition during postoperative perichemotheraputic period.
