Nineteen patients with histologically proven superficial bladder cancer (Ta, T1) were treated with intravesical instillation of 30 mg of adriamycin (ADM) dissolved in 24 ml physiological saline plus 15 mg of verapamil (VR) (6 ml) every day for 10 days. In spite of the short period of treatment, 6 of the 18 evaluable patients (33.3%) showed complete response(More)
A number of human cell lines derived from well-differentiated, myxoid/round cell, or pleomorphic liposarcoma have been described. To our knowledge, however, no human cell line established from dedifferentiated liposarcoma has been reported. In this study, we established a new human cell line, FU-DDLS-1, which originated from a dedifferentiated liposarcoma(More)
We reviewed 57 cases of Stage IV renal cell carcinoma to clarify the factors influencing prognosis and to evaluate the value of nephrectomy. Cumulative survival from the initial diagnosis was analyzed with respect to the patients' age, sex, side of primary tumor, initial performance status (PS), site of metastasis, and nephrectomy. Overall survival for the(More)
The goal of this study was to develop a strategy for the selective destruction of cancer cells by ultrasonic irradiation in the presence of an antibody-conjugated photosensitizer. To this end, a photoimmunoconjugate (PIC) was prepared between ATX-70, a photosensitizer of a gallium-porphyrin analogue, and F11-39, a high affinity monoclonal antibody (MAb)(More)
OBJECTIVES To design a proper follow-up for cystectomy and ileal conduit urinary diversion for primary bladder transitional carcinoma, we compared the radiographic characteristics of recurrent malignant upper tract lesions with those of benign ureteroileal anastomosis strictures. METHODS Over a 20-year period, we followed 61 patients who underwent(More)
BACKGROUND A recurrence of bladder tumors following surgery for transitional cell carcinoma of the upper urinary tract is not rarely observed. A prospective randomized study was conducted to examine the significance of prophylactic intravesical instillation of mitomycin C (MMC) and cytosine arabinoside (Ara-C) to prevent recurrent bladder tumors after(More)
Sarcomatoid carcinoma of the urinary bladder is a rare entity, in which both the histogenesis and biological behavior remain controversial. We herein describe the clinicopathologic and immunohistochemical profiles of sarcomatoid carcinomas and discuss the significance of cell adhesion molecules in the development of this peculiar neoplasm. The authors(More)
A follow-up study was made on 225 Japanese patients with superficial bladder tumors who were treated postoperatively with intravesical instillation of cytosine arabinoside and mitomycin C nineteen times during one year. Cumulative recurrence rates of the tumor were 16.7 and 41.9 per cent during the first 1 and 3.5 years after surgery, respectively. These(More)
A case of monophasic synovial sarcoma of the prostate in a 37-year-old man is reported. Histologically, the tumor was chiefly composed of uniform spindle and oval cells, which often formed interlacing fascicles resembling those of fibrosarcoma. In some areas, the compact fascicles of tumor cells alternated with hypocellular myxoid tissue bearing a(More)
