A primary neoplasm arising in a vesical diverticulum was cystectomizedand analyzed by step-sectioning of the whole bladder in an attemptto determine the carcinogenic process. Serial sections of thecystectomy specimen revealed a small area of mild dysplasiain the mucosa of the bladder and the diverticulum without atumor. Most of the mucosal cells in the tumor-bearing diverticulumwere desquamated, but a small area of dysplasia in the remainingcells was also observed. 相似文献

Background: Thrombocytosis has been reported in many types of malignancies and has been studied as a prognostic factor. In the present study, we examined the incidence of thrombocytosis in patients with renal cell carcinoma (RCC) in order to evaluate the prognostic value of thrombocytosis. Methods: One hundred and ninety‐six patients treated by radical nephrectomy for RCC were enrolled in this study. We divided the patients into a normal platelet count group and a thrombocytosis group according to the presurgical platelet count. The two groups were compared pathologically and clinically, including prognosis. Results: Thrombocytosis was present in 16 patients (8.2%). Platelet counts had normalized after nephrectomy in all patients with thrombocytosis. There was no correlation between histological type or grade and thrombocytosis. However, there were correlations between thrombocytosis and tumor size and tumor stage. Patients with thrombocytosis had a worse prognosis than patients without thrombocytosis (P = 0.0028). When adjusted for stage or tumor size, the correlation was limited to low stage (stage 1 + 2: P = 0.0041, stage 3 + 4: P = 0.2983) or small tumors (tumor size: ≤4 cm, P = 0.0021; 4–7 cm, P = 0.0142; >7 cm, P = 0.8158). Conclusion: Thrombocytosis is an inexpensive and easy tool with which to evaluate the prognosis of RCC patients in daily medical practice. 相似文献

Abstract: A 31-year-old man, cook, who had had persistent watery diarrhea for about a month visited our hospital. He had already been diagnosed as having pachydermoperiostosis. An examination of the upper gastrointestinal tract revealed that he had giant gastric rugae. The histology was compatible with hypertrophic gastritis accompanied with marked hyperplasia of the fundic gland and foveolar epithelia. The output of gastric juice was high in volume, although its acidity normal. The barium transit time of the small intestine was reduced to 15 minutes. His diarrhea was, thus, considered to be induced by gastrointestinal hyperfunction. The patient's glucose tolerance was abnormal and basal Cortisol secretion level was high. Pachydermoperiostosis has been the focus of attention for skin and bone changes, and the frequency of this disease with endocrine disorders seems rather high, but accompanying gastrointestinal disorders have so far not often been reported in Japan. The results of our investigation strongly suggest that pachydermoperiostosis is a systemic disease. 相似文献

BACKGROUND: The influence of dialysis modality on the acute rejection (AR) rate after renal transplantation is controversial. We investigated whether the pretransplant dialysis modality correlated with the lymphocyte subset populations and the incidence of AR after renal transplantation. METHODS: Thirty-eight first living renal transplant recipients, consisting of 22 patients on pretransplant hemodialysis (HD) and 16 patients on pretransplant peritoneal dialysis (PD), were studied. Peripheral blood samples were taken on days -1 through 28 after transplantation, and the lymphocyte fractions were exposed to the monoclonal antibodies anti-CD3, CD19, CD4, CD8 and CD28 for a flow cytometer analysis. Biopsy specimens were obtained at the time of presumed AR episodes and on day 28 after transplantation. RESULTS: The PD patients had a higher frequency of AR (37.5% in PD vs 9.1% in HD patients, P = 0.034). In contrast, two HD patients showed graft loss at 18 and 30 months after transplantation. The increases of CD3, CD19, CD4 and CD4+ CD28+ cells in the PD patients occurred earlier than in the HD patients and the numbers of these cells in the PD group were higher than those in the HD between days 3-28 after transplantation, most significantly on day 7. CONCLUSIONS: These findings suggest that the PD patients with similar clinical characteristics could potentially have a higher immunocompetence and immune responsiveness associated with a higher rate of AR in the early stage of renal transplantation when compared with the HD patients. 相似文献

In order to clarlfy the cell kinetics of colorectal villous tumors (VT), 21 villous adenomatous areas and 12 carcinomatous areas within villous adenomas were investigated for proliferative activity and apoptosis and compared with a series of 41 tubular tumors (TT), demonstrating elements of intramucosal carcinomas as well as tubular adenomas (so-called carcinoma in tubular adenoma). Proliferation was estimated in terms of KI-67 labeling indices and mitotic indices, and apoptosis was assessed by DNA nick-end labeling to give apoptotic Indices. Apoptotic indices of villous adenomatous and carcinomatous regions were significantly lower than the values for their tubular counterparts. Kl-67 labeling indices were also significantly lower for adenoma components. Apoptotic indices, Ki-67 labeling indices and mitotic Indices increased with atypia raised in tubular adenoma components. Correlations of mitotic indices with apoptotic indices, Ki-67 labeling Indices with apoptotic indices and mitotic Indices with Ki-67 labeling indices were found for each villous tumor group and tubular tumor group, and the apoptosis and proliferation ratios for villous tumors were relatively low, suggesting a tendency for greater growth due to less cell deletion. Although this is only one of the biological features of villous tumor groups, it might play a major role in generation of malignancy. 相似文献
