PURPOSE It has been shown in many carcinomas that the proliferation rate and number of argyrophilic nucleolar organizer regions (AgNOR) are associated with tumor aggressiveness. However, in bladder tumor the significance of the correlation between the number of AgNOR and tumor behavior remains controversial. Therefore, it would be helpful if a new technique(More)
BACKGROUND Bleomycin is one of the key drugs used in induction chemotherapy for testicular cancer. Pulmonary toxicity is the major and potentially fatal adverse side-effect of this drug. METHODS To evaluate the risk factors for bleomycin pulmonary toxicity, we retrospectively analyzed the cases of 20 men treated for metastatic testicular cancer at Tsukuba(More)
PURPOSE Evaluation of prognostic significance of nucleolar organizer regions (NORs) in renal cell carcinoma (RCC). MATERIALS AND METHODS Nuclear organizer regions were quantified in a series of 59 cases of RCC by the silver colloid method, and the NOR index was obtained from the ratio between mean NOR counts in each neoplastic nucleus and in normal(More)
PURPOSE We have previously demonstrated that the AgNOR count in proliferating cells is a predictor of tumor recurrence in superficial bladder tumor (J. Urol. 162 (1999), 63-68). In the present study, we evaluate the type of AgNOR associated with cell cycles as a prognostic factor in invasive bladder tumor using a double staining technique employing both(More)
We examined nucleolar organizer region (NOR) indices on 13 bladder tumors on both squash-prepared specimens and paraffin embedded specimens stained by silver-colloid method. It was noted that; 1. The nuclear size was enlarged by squashing, 2. Aggregated NOR dots were dispersed, 3. Uniformity of microscopic phase of the dots was obtained, 4. Squash specimens(More)
A 60-year-old man who had renal cell carcinoma with renal hypofunction underwent partial nephrectomy followed by alpha-interferon therapy (LHBI 3 x 10(6) IU/day intramuscular injection for 4 weeks, then twice a week for 6 months). Glomerular filtration rate slightly decreased to 28. 5 from 32.6 ml/m after partial nephrectomy. On single injection of IFN, its(More)
PURPOSE We reviewed cases of intrascrotal tumors treated at our institution except for germ cell testicular tumors. PATIENTS AND METHODS From 1977 to 1998 (22 years), 120 cases of intrascrotal tumors treated at the University of Tsukuba. Of these, 15 cases (12.5%) were not germ cell testicular tumors. The patients' ages varied between 2 and 77 years with(More)
AIM To retrospectively investigate the biochemical outcome following delayed radiotherapy in patients with prostate cancer. PATIENTS AND METHODS From July 2000 to November 2008, 144 consecutive patients with localized prostate cancer underwent radiotherapy and androgen-deprivation therapy. Biochemical progression-free survival was compared in patients who(More)
A 41-year-old man incidentally found to have a right renal and left large lung tumor in the course of screening for liver dysfunction was admitted to our hospital. Needle biopsy of each tumors revealed histologically renal cell carcinoma and pulmonary blastoma. The renal tumor grew rapidly and soon he died of DIC. Autopsy was performed and the final(More)
