Objective(s): BONENAVI, a computer-aided diagnostic system, is used in bone scintigraphy. This system provides the artificial neural network (ANN) and bone scan index (BSI) values. ANN is associated with the possibility of bone metastasis, while BSI is related to the amount of bone metastasis. The degree of uptake on bone scintigraphy can be affected by the type of bone metastasis. Therefore, t...

  Background and Objective: Oral cancer accounts for less than 3% of all cancers. Despite recent improvement in diagnostic and treatment methods, the overall survival of the disease is unfavorable. Several studies have been performed to assess factors influencing lymph node metastasis and prognosis. The aim of this study was to evaluate some clinical and pathological factors influencing lymph ...

Introduction: Thermal ablation by microwave (MWA) has proven efficacy in treatment of primary and metastatic cancers. Soft tissue tumors could be ablated completely using MWA. However, bony tissue metastasis particularly spinal vertebral metastasis ablation has not reported yet. Case presentation: A 50 year old male patient with primary diagnosed colon cancer undergone surgical resection of ...

intraocular metastatic tumors have been increasingly reported in the recent past. unlike choroidal metastasis, metastasis to retina is very rare and so far has been reported in very few case reports only. case presentation : a 56 year-old male who presented with a history of adenocarcinoma of the cecum and underwent lap colectomy for the primary cecal tumor, received adjuvant chemotherapy for a...

hepatoblastoma (hb) is a rare tumor of infancy and childhood manifesting with hepatomegaly and abdominal distention. it is seen with increased frequency in association with congenital hemihypertrophy and renal anomalies. metastases to other organs, including the lungs, lymph nodes and even ovaries is well known. but cerebral metastasis of this tumor, especially in the absence of metastasis to o...

Evaluation of the relationship between clinicopathological and immunohistochemical risk factors for liver metastasis, including CD10 expression, is meaningful in colorectal carcinoma (CRC). The purpose of the present study was to clarify what kind of risk factors are significant and independent factors for the development of liver metastasis in CRC. Sixty cases of advanced CRC with synchronous ...

introduction: breast cancer is one of the provalent cancers in the world. this cancer as well as other solid tumors, in the course of its development has phases in this order: epithelial dysplasia, carcinoma insitu, invassiveness and metastasis. breast cancer diagnosis is generally made with pathology methods. in this survey, measuring angiostatin (which is one of the most important and potent...

Hepatoblastoma (HB) is a rare tumor of infancy and childhood manifesting with hepatomegaly and abdominal distention. It is seen with increased frequency in association with congenital hemihypertrophy and renal anomalies. Metastases to other organs, including the lungs, lymph nodes and even ovaries is well known. But cerebral metastasis of this tumor, especially in the absence of metastasis ...
