Between 1998 and 2007, we treated 157 patients with malignant soft tissue tumors. Patients with obvious lymph node metastasis, metastasis from bone or soft tissue sarcoma, and with obvious advanced stage disease which had multiple metastases were excluded from the present analysis. Finally, sixteen of the 157 patients were diagnosed to have soft tissue metastasis from carcinomas or hematopoieti...

Radiosurgery and brachytherapy are potentially useful treatment techniques that sparingly applied in pediatric oncology. They often used the setting of reirradiation for recurrent or metastatic tumors. Reirradiation children with tumors is complicated by tolerance critical organs potential risks overall long-term dose-dependent complications. We review current literature available support use r...

in this study, l-131-mibg imaging was performed in 44 patients with clinical suspicion of tumors originating from neuro-endocrine system. the patients were referred to our department following plasma and urinary measurement of epinephrine, norepinehrine and vanilmandelic acidfvma). radionuclide imaging was performel as a comparative or confirmatory measure in all patients who had previous abdom...

  Background: Tumors involving the hand skeleton are rare. However, a basic knowledge of hand tumors is necessary for every clinician. This is due to the importance of distinguishing typical benign tumors from life or limb threatening malignant ones. Methods: This study is a review of 99 cases of osseous hand tumors presented to the department of orthopedic surgery, Imam Khomeini Hospital in Te...

Primary cardiac tumors are very rare. Cardiac sarcomas can be detected at any age, regardless of gender. At diagnosis, these mostly symptomatic and one-third metastatic. Undifferentiated pleomorphic account for 1.7% all tumors, typically localized in the left atrium, involve mitral valve. Here we present a case atrial undifferentiated sarcoma with myogenic differentiation that clinically radiol...

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 tum...

Background: CD4+ and CD8+ T cells are the main types of lymphocytes in cell-mediated immunity and play a central role in the induction of efficient immune responses against tumors. The frequencies of T cell subtypes in the peripheral blood and tumor tissues, and draining lymph nodes (dLN) can be considered as useful markers for evaluation of the immune system in cancers. Methods: In this study,...

Background: About half of all brain tumors are primary, and the remainder are metastatic. Tumors of the nervous system have unique characteristics that set them apart from neoplastic processes elsewhere in the body. The World Health Organization (WHO) has classified central nervous system (CNS) tumors as grades I to IV in increasing order of malignancy. The goal of this study was to follow the...
