The incidences of all primary neoplasms in the testes and accessory reproductive organs of 51,230 male Fischer 344 (F344) rats and 46,752 male B6C3F1 mice were obtained from the pathology data base of more than 300 long-term toxicity/carcinogenicity studies performed for the National Toxicology Program. The overall incidence of reproductive system neoplasms in male F344 rats was 81.5%. The most...

Background: The most common intracranial neoplasm worldwide is meningioma, followed by gliomas, and then pituitary adenomas. There are geographical differences in the pattern of occurrence neoplasms. purpose this study to establish different histological types neoplasms with their age sex distributions our environment – Lagos, Nigeria.The patterns, age, gender all diagnosed within period at Dep...

introduction the application of immunohistochemical method has resulted in marked improvement of the microscopic diagnosis of neoplasms combined with h&e; staining. although unique cellular antigens have not been found in salivary gland neoplasms, multiple less specific immunomarkers have been used and may be helpful in elucidating the role of myoepithelial differentiation in those neoplasms. t...

results strong participation was associated with a younger age, higher educational level, higher incomes, previous history of cancer, previous family history of cancer, one or two prior mammographies, more correct recognitions of mammography, recall rate, and breast cancer risk. if the false-positive result occurred, 83.9%, 81.9% and 77.3% of the women agreed or strongly agreed to participate i...

primary cardiac tumors are quite rare, especially in the pediatric age group, and their atypical presentations often prevent a timely diagnosis. most primary cardiac tumors in the pediatric age group are benign. fibromas are generally reported as the second most common primary cardiac tumors in the pediatric age group. these neoplasms are often intramural and involve the left ventricular free w...

background: breast cancer is considered as the most common as well as most effective malignancy in adult female population. it leads to deep psychological and emotional problems such as depression. although findings of numerous studies revealed a significant relation between spiritual well-being and depression in cancer patients, some reasons such as paradoxical findings in foreign researches a...

BACKGROUND Intraductal papillary mucinous neoplasms (IPMN) have been reported to be associated with concurrent, distinct pancreatic ductal adenocarcinoma (con-PDAC) in about 8% (range, 4-10%) of resected branch duct (BD) lesions. In addition, other pancreatic and ampullary tumors are occasionally diagnosed with IPMN in patients undergoing pancreatic surgery. The objective of this study is to de...

OBJECTIVE Little is known about the incidence of secondary neoplasms among survivors of retinoblastoma in Japan. The objective of our study was to analyze the cumulative incidence rate of secondary neoplasms following retinoblastoma and to investigate the risk factors of developing secondary neoplasms. METHODS We conducted a retrospective cohort study of 754 retinoblastoma patients who visite...

Human T-cell lymphotropic virus type I (HTLV-I) associated adult T-cell leukemia/lymphoma (ATLL) occurs endemically in southwestern Japan, the Caribbean, and West Africa, but occurs sporadically in most of the rest of the world. However, because ATLL and non-HTLV-I associated T-cell neoplasms share overlapping clinicopathologic features, the prevalence of ATLL in nonendemic regions is unknown. ...
