Intravesical instillation of anti-cancer drugs for superficial urinary bladder cancer is generally carried out with the aim of prophylaxis against recurrence and chemotherapy against tumor. But since sensitivity of tumor cells to each anti-cancer drug differs individually, the anti-cancer drug to be used should also be decided individually. We selected a new sensitivity test, ATP-sensitivity-assay, which measures intracellular adenosine triphosphate (ATP) volume by Luciferin-Luciferase reaction, for the decision of the anti-cancer drug. In this paper, we evaluated the direct anti-tumor activity of the drugs that were decided by ATP-sensitivity-assay of intravesical chemotherapy. Six drugs, that are Doxorubicin (ADM), Mitomycin C (MMC), Pirarubicin (THP-ADM), Cytarabine (Ara-C), Bleomycin (BLM) and Cisplatin (CDDP) were tested in this research and size of tumors of six patients reduced to 34-93% after 6 times' installation. A woman got cystitis induced by ADM after 3 times' instillation but instillation was completed. ATP-sensitivity-assay is useful for deciding the anti-cancer drugs for intravesical chemotherapy and prophylaxis for superficial bladder cancer.
