INTRODUCTION Human antigen R (HuR) regulates the stability of mRNA and is associated with cell proliferation, angiogenesis, and lymphangiogenesis. However, the clinical significance and pathological role of HuR in bladder cancer remains unclear. The main objective of this investigation was to clarify the relationships between HuR expression and clinical(More)
AIMS Twist has been reported to play crucial roles for malignant aggressiveness; however, detailed pathological significance of Twist in renal cell carcinoma (RCC) is not fully understood. The present study was to clarify clinical significance and molecular functions of Twist in patients with RCC. METHODS Twist expression was examined by(More)
BACKGROUND Neoadjuvant hormonal therapy (NHT) is performed to improve the outcome in organ-confined prostate cancer. However, there is little information regarding the relationship between angiogenesis and NHT. The aim of this study was to identify a suitable method to evaluate the angiogenic status of tissue, and to determine the prognostic value of this(More)
Heme oxygenase (HO)-1 is upregulated in malignancies and, in turn, regulates other cancer-related factors. Although HO-1 expression has been associated with cigarette smoking under various pathologic conditions, little is known about their association in patients with bladder cancer. HO-1 expression was assessed in 215 formalin-fixed bladder cancer(More)
Cardiac metastasis of renal cell carcinoma is an exceptional event, particularly when there is lack of inferior vena cava involvement. Indeed, only a few cases have been reported worldwide thus far. Moreover, discussion of treatment and follow-up strategies for cardiac metastasis of renal cell carcinoma is important because of the high risk of sudden death.(More)
In patients with advanced urothelial cancer (UC), a combination of cisplatin (CDDP) and gemcitabine (GEM) is the most commonly used first-line systematic chemotherapy regimen. Although no standard regime for the treatment of CDDP-resistant UC has been established, GEM-based regimens are frequently used in these patients. In other types of cancer, human(More)
Clinicopathological features and prognosis of metastatic renal cell carcinoma (mRCC) vary by histopathological type. In this study, we analyzed these relationships with regard to non-clear cell RCC (nccRCC). We also analyzed the therapeutic trends for patients with mRCC. We initially identified 367 patients who were diagnosed with RCC and treated in our(More)
Various regimens including molecular targeted agents have been examined in patients with cisplatin (CDDP)-resistant urothelial cancer (UC). However, some studies have been stopped owing to the development of severe adverse events. The main aim of this study was to examine the anticancer effects, changes in the quality of life (QoL), and safety of combined(More)
Cigarette smoking is a major risk factor for urothelial cancer (UC) development. However, the associations between smoking and changes in the pathological characteristics and molecular expression of cancer-related molecules in upper tract (UT) UC have not been fully elucidated. We investigated the associations between smoking status and cancer-related(More)
Met is a tyrosine kinase receptor that is considered to be a proto-oncogene. The hepatocyte growth factor (HGF)-Met signaling system plays an important role in tumor growth, invasion, and metastasis in many types of malignancies. Furthermore, Met expression has been reported to be a useful predictive biomarker for disease progression and patient survival in(More)
