Bladder tumor is the most common malignant tumor in urinary system and always companied with lymph node metastasis. The accurate staging plays a significant role in treatment for bladder tumor and prognostic evaluation, and the distant metastasis predicts worse prognosis. The objective of this study was to assess the clinical significance of (18)F-FDG PET/CT imaging in diagnosing bladder tumor metastasis lesions. A retrospective analysis of 60 patients with bladder tumor from October 2008 to May 2010 was done. The patients were stratified based on the imaging technique. Among all 60 cases, besides the primary lesion, 81 suspected lesions were spotted and 73 confirmed as metastasis, including 50 lymph node metastases, 22 distant metastases, and 1 bone metastasis. For PET/CT imaging, its sensitivity was 94.5%, specificity 87.5%, positive predictive value 98.6%, negative predictive value 63.6% and accuracy 93.8% respectively. For CT, its sensitivity was 82.2%, specificity 50%, positive predictive value 93.8%, negative predictive value 23.5% and accuracy 79% respectively. PET/CT imaging was superior to CT in sensitivity, specificity and accuracy. In conclusion, (18)F-FDG PET/CT imaging is more significant in diagnosing bladder tumor metastasis lesions.

Cutaneous metastases from urothelial carcinoma of the bladder are a rare disease. In previous reports, the most common metastatic cutaneous lesions were non-tender nodules on the abdominal skin. We report a patient with bladder urothelial carcinoma with cutaneous metastases initially presenting as right leg and suprapubic lymphedema. Bladder tumor was the incidental finding by magnetic resonance venography. Urothelial carcinoma (clinical stage IV) was diagnosed, and chemotherapy was performed. Extensive painful erythematous plaques with an erysipelas-like appearance located on the suprapubic area, chest and abdomen were noted, and cutaneous metastases were confirmed by histopathology. Subsequently, extensive scrotal and prepuce ulcerative changes developed. This paper reports a rare case of extensive cutaneous metastasis of bladder urothelial carcinoma who presented an interesting clinical course.

The consumption of extra virgin olive oil (EVOO), a common dietary habit of the Mediterranean people, seems to be related to a lower incidence of certain types of cancer including bladder neoplasm. Metastases are the major cause of bladder cancer-related deaths and targeting cell motility has been proposed as a therapeutic strategy to prevent cancer spread. This study aimed to investigate the potential antimetastatic effect of total phenols extracted from EVOO against the human transitional bladder carcinoma cell line T24. We also aimed at verifying that EVOO extract exerts cytotoxic effect on tumor cells without affecting normal urothelial fibroblasts. Our results show that EVOO extract can significantly inhibit the proliferation and motility of T24 bladder cells in a dose-dependent manner. In the same experimental conditions fibroblast proliferation and motility were not significantly modified. Furthermore the enzymatic activity of MMP-2 was inhibited at nontoxic EVOO extract doses only in T24 cells. The qRT-PCR revealed a decrease of the MMP-2 expression and a simultaneous increase of the tissue inhibitors of metalloproteinases expression. Our results may support the epidemiological evidences that link olive oil consumption to health benefits and may represent a starting point for the development of new anticancer strategies.
