The images presented below were from a man, at the age of 80, who was admitted to hospital with recurrent urinary tract infection. Magnetic resonance imaging (MRI) was performed after initial examination. Conventional MRI showed multiple diverticulum in bladder and one of them had contact sigmoid colon via fistula tract (Figure-1). Diffusion weighted images (DWI) showed restricted diffusion in ...
Cigarette smoking (CS) is the main risk factor for bladder cancer development. There are more than 100 carcinogens present in cigarette smoke. Among the potential mediators of CS-induced alterations is nuclear factor-kappa (NF-kappaB), which is responsible for the transcription of genes related to cell transformation, tumor promotion, angiogenesis, invasion and metastasis. Curcumin is a polyphe...
Bladder adenocarcinoma is a rare histological subtype of bladder cancers, with variant subtypes including pure primary signet-ring cell carcinoma (PSRCC) which accounts for only 0.52% of all primary neoplasms of the bladder [1]. The first two cases were reported by Saphir [2]. A review of the literature reveals no more than 100 published cases. The prognosis for patients with SRC is poor, attri...
The carcinogenicity of aflatoxin BI (AFB,) has been under evaluation in nonhuman primates for the past 13 years. A total of 47 Old World monkeys, chiefly rhesus and cynomolgus, have received AFB, i.p. (0.125 to 0.25 mg/kg) and/or p.o. (0.1 to 0.8 mg/kg) for 2 months or longer, and 12 are currently alive and without evidence of tumor. Thirteen of the 35 mon keys necropsied to date (37%) develope...
In numerous patients with multiple primary malignant neoplasms, it is difficult to determine whether the mass is benign or malignant, and the method to treat these lesions is controversial. For patients with a history of cancer, a point of high-risk for the development of a second primary tumor occurs following a 10-year gap. To the best of our knowledge, to date, there has been no large clinic...
INTRODUCTION The aim of this study was to investigate the probable differences in P53 expression between papillary urothelial neoplasm of low malignant potential (PUNLMP) and varying grades of transitional cell carcinoma (TCC) of the bladder. MATERIALS AND METHODS Ten biopsy specimens of the patients with PUNLMP, 20 of the patients with papillary low-grade TCC, 20 of those with invasive high-...
BACKGROUND Urothelial papilloma and non-invasive papillary carcinoma are common neoplasms of the urinary bladder. Distinguishing papillomas and papillary carcinomas, especially the low grade type, is often debatable on the basis of histological features alone. MATERIALS AND METHODS We investigated immunohistochemical expression of cytokeratin 20 (CK20), p53, and Ki-67 in a group of 20 urothel...
Studies of pancreatic cancer in the setting of second primary malignant neoplasms can provide etiologic clues. An international multicenter study was carried out using data from 13 cancer registries with a registration period up to year 2000. Cancer patients were followed up from the initial cancer diagnosis, and the occurrence of second primary malignant neoplasms was compared with expected va...
The carcinogenicity of aflatoxin B1 (AFB1) has been under evaluation in nonhuman primates for the past 13 years. A total of 47 Old World monkeys, chiefly rhesus and cynomolgus, have received AFB1 i.p. (0.125 to 0.25 mg/kg) and/or p.o. (0.1 to 0.8 mg/kg) for 2 months or longer, and 12 are currently alive and without evidence of tumor. Thirteen of the 35 monkeys necropsied to date (37%) developed...
