PURPOSE Systemic therapy for advanced bladder cancer has not changed substantially in more than 2 decades and mortality rates remain high. The recognition of HER2 over expression in bladder cancer has made HER2 a promising therapeutic target. T-DM1, a new drug consisting of the HER2 antibody trastuzumab conjugated with a cytotoxic agent, has been shown in(More)
Renal cell carcinoma (RCC) accounts for 80–95 % of kidney tumors, and approximately 30 % of RCC patients have metastatic disease at diagnosis. Conventional chemotherapy is not effective in patients with metastatic RCC (MRCC); therefore, immunotherapy with interferon-α (IFN-α) has been employed to improve survival. However, the response rate of MRCC to IFN-α(More)
Following Corrado et al. (2009), we measure intangible assets at the listed firm level in Japan. Compared to the conventional Tobin’s Q, the revised Q including intangibles is almost 1 on average, as suggested by Hall (2000 and 2001). The standard deviation of the revised Q is smaller than that of the conventional Q. Estimation results based on Bond and(More)
Hemorrhagic cystitis often arises after cyclophosphamide (CYP) administration. As yet, however, the mechanism involved in its pathogenesis is unknown. In this study, it was found that the Fc receptor γ chain (FcRγ)- caspase recruitment domain-containing protein 9 (CARD9)-dependent pathway rather than the myeloid differentiation primary response gene 88(More)
Intravesical inoculation of Mycobacterium bovis bacillus Calmette-Guérin (BCG) has been used for the treatment of bladder cancer. Recent studies implied the requirement of neutrophil infiltration for the antitumor effect. In this study, we found that IL-17 was produced in the bladder after BCG treatment, preceding the infiltration of neutrophils.(More)
BACKGROUND/AIM Salvage androgen-deprivation therapy (ADT) is standard treatment for recurrent prostate cancer after curative therapy. However, the prognostic impact of different treatment modalities on the time to castration resistance remains unclear. In this study, we investigated the prognosis of men treated with salvage ADT after initial radical(More)
Interleukin-17A (IL-17A)-producing γδ T cells differentiate in the fetal thymus and reside in the peripheral tissues, such as the lungs of naïve adult mice. We show here that naturally occurring γδ T cells play a protective role in the lung at a very early stage after systemic infection with Candida albicans. Selective depletion of neutrophils by in vivo(More)
PURPOSE Serum testosterone suppression during androgen deprivation therapy has been reported to affect the efficacy of androgen deprivation therapy. However, the factors impacting hormonal variations during androgen deprivation therapy remain unclear. Therefore, in this study we investigated the significance of missense polymorphisms in the gene encoding(More)
Mycobacterium bovis Bacillus Calmette-Guérin (BCG) is used for the treatment of bladder cancer. The recruitment of neutrophlis to the bladder after BCG instillation exerts anti-tumor activity against bladder tumor. We have recently demonstrated that interleukin (IL)-17A produced by γδ T cells played a role in the recruitment of neutrophlis to the bladder(More)
AIM Although the impact of testosterone or obesity on the efficacy of androgen-deprivation therapy (ADT) has been reported, there exist few comprehensive analyses on the impact of these factors on ADT outcome. Therefore, in the present study, we investigated the relationship between serum testosterone or body mass index (BMI) and prognosis among men treated(More)
