[Therapeutic efficacy of fosfomycin and cisplatin alone or in combination on human urogenital cancer by subrenal capsule assay].
Experimental therapies of human urogenital cancer with fosfomycin and cisplatin were performed by subrenal capsule assay. The subrenal capsule assay was applied for 10 cell lines, consisted of 4 renal cell carcinomas, 2 renal pelvic carcinomas, 2 carcinomas of the urinary bladder, one prostatic carcinoma, and one testicular tumor. The efficacy of each drug was evaluated by measuring the tumor growth, and compared the mean tumor volume of treated with that of untreated groups. The growth inhibition rate in fosfomycin group was 60% and in cisplatin group was 80%, whereas that of the combination therapy of both fosfomycin and cisplatin was 50%. This indicates that the combination therapy reduced the antitumor effect. Further, the histological findings also showed a similar pattern in both kidney and tumor tissues between the treated and untreated groups.
