Purpose: There are a lot of experiences about using bone-like materials in order to replace bone defects, especially those which are caused by cancer therapy. The most suitable materials for this purpose are bioceramics. The investigations have been shown that bioceramics are able to induce proliferation of osteoblast as well as bone matrix synthesis in - vivo.The aim of the present study is to...
Bone is a common site of metastasis for various types cancer cells, including breast cancer, and the consequent skeleton-related events observed in patients are severe often fatal. Currently, it widely accepted that cancer-associated fibroblasts (CAFs) confer metastasis-promoting property to cells. Furthermore, clinical observations suggest CAFs mediate bone tropism metastatic Therefore, deeper...
Introduction: 18F-FDG PET/CT provides very effective results in detecting metastases of breast cancer. In our study, we investigated the relationship between maximum standard uptake value (SUVmax) and prognostic pathologic factors in breast cancer cases with isolated bone metastasis and whether there was any difference in terms of prognostic pathologic factors betwee...
background: understanding the differences in genetics of malignancies is crucial for therapeutic decisions. this systematic review was conducted to evaluate the current evidence on genetics of bone tumors in the context of pediatric cancer. material and methods: we performed a systematic review of the literature published on genetics of pediatrics bone tumors, using pubmed, google scholar, scie...
skeletal involvement is the second most common site of metastases after lymph nodal metastases in patients with prostate cancer. the skeletal metastases from prostate cancer are osteoblastic in nature and show increased tracer avidity on the bone scan. focal tracer avid lesion in skeleton especially in skull requires the careful examination by further investigation. the patients with skull meta...
Objective(s): Prostate cancer (PC) is the most common cancer in men over 50 years of age. Bone scintigraphy is still performed in many institutions at the time of primary diagnosis. We aimed to evaluate the role of bone scan in the primary staging of PC in regard of different risk groups. Methods: A retrospective analysis of bone scans i...
جایگزینی دندان های از دست رفته به وسیله ایمپلنت دندانی به فراوانی انجام میشود. برای اینکه ایمپلنت به طور بهینه جایگزین شود باید در استخوان ایده ال جایگذاری شود که البته این نقایص قابل ترمیم هستند، یکی از این روشها guided bone regeneration است.
Background: The fundamental principles of internal targeted alpha therapy for cancer were established many decades ago.The high linear energy transfer (LET) of alpha radiation to the targeted cancer cellscauses double strand breaks in DNA. At the same time, the short range radiation spares adjacent normal tissues. This targeted approach complements conventional external beam radiotherapy and ch...
Skeletal involvement is the second most common site of metastases after lymph nodal metastases in patients with prostate cancer. The skeletal metastases from prostate cancer are osteoblastic in nature and show increased tracer avidity on the bone scan. Focal tracer avid lesion in skeleton especially in skull requires the careful examination by further investigation. The patients with skull meta...
Leukemia is the most common childhood cancer and accounts for 30-40% of all malignancies. A retrospective review was performed of the hospital records of 9 children, 6 boys and 3 girls, aged from 2.5 to 15 years with ALL initially referred to Nemazee hospital Nuclear medicine center for whole body bone scanning between 2000 and 2002. Bone marrow pathology established ALL (L1) in two and ALL (...
