BACKGROUND The International Neuroblastoma Pathology Classification was established in 1999 for the prognostic evaluation of patients with neuroblastic tumors (NTs). METHODS Pathology slides from 746 NTs (the Children's Cancer Group [CCG]-3881 and CCG-3891 studies) were evaluated according to the International Classification. First, prognostic effects of the morphologic indicators (grade of n...

A brain tumor is a very common and devastating malignant that leads to shorter lifespan if not detected early enough. Brain classification critical step after the has been identified create an effective treatment plan. This study aims investigate three deep learning tools, VGG-16 ResNet50 AlexNet in order detect using MRI images. The results performance are then evaluated compared accuracy, pre...

a case of pleomorphic adenoma in sweat gland is reported here. the histopathologic report confirmed the diagnosis. pleomorphic adenoma is most common in salivary glands but very rare in sweat glands. pleomorphic adenoma in sweat gland and the similar tumors of eccring sweat gland are described that bear a striking resemblance to pleomorphic adenomas of salivary gland. upon closer examination, t...

absract a case of 69- year-old woman with large pelvic mass and ascites is reported in this paper. with the exception of mild pelvic pain and a pelvic mass in pelvic , she had no symptom or sign . all routine and hormonal lab tests and tumor marker's were normal. the mri revealed a large mass in anterosuperior of uterus, and left ovary was situated in neighborhood of pelvic mass.her uterus norm...

In this paper, a novel fully automatic classification method of breast tumors using ultrasound (US) image is proposed. The proposed method can be divided into two steps: “ROI generation step” and “ROI classification step”. In the ROI generation step, the proposed method focuses on finding a credible ROI instead of finding the precise location of the breast tumor. In the ROI classification step,...

The entity known as pituitary carcinoma has been traditionally defined a tumor of adenohypophysial cells that metastasizes systemically or craniospinally independent the histological appearance lesion. Reported cases have clinically and histologically resembled their non-metastatic counterparts were classified adenomas; majority initially diagnosed adenomas, with progression spread, diagnosis w...

Background Molecular markers provide important biological and clinical information related to the classification of brain tumors, and the integration of relevant molecular parameters into brain tumor classification systems has been a widely discussed topic in neuro-oncology over the past decade. With recent advances in the development of clinically relevant molecular signatures and the 2016 Wor...

BACKGROUND AND PURPOSE The pattern of contrast leakage from DSC tissue signal intensity time curves have shown utility in distinguishing adult brain neoplasms, but has limited description in the literature for pediatric brain tumors. The purpose of this study is to evaluate the utility of grading pediatric brain tumors with this technique. MATERIALS AND METHODS A retrospective review of tissu...
