Background: Breast cancer is known as the most widely recognized dangerous tumors; therefore, the most common reason for mortality among all instances of harmful neoplastic illness in females. This is because the lack of specific signs and symptoms at the early stage and at the aggressive nature. Currently, breast cancer treatment such as chemotherapy, surgery and radiotherapy has not been effe...
Secondary angiosarcoma is an aggressive tumor that can develop in breast cancer patients treated with conserving therapy and radiotherapy. The symptoms can be misleading, whereas mammography and fine-needle aspiration (FNA) are typically negative in early stage of the disease. A high grade of clinical suspicion is very important for early diagnosis. A case of angiosarcoma involving breast paren...
BACKGROUND AND PURPOSE Tissue hardness (induration), pain and tenderness are common late adverse effects of curative radiotherapy for early breast cancer. The purpose of this study was to test the efficacy of IH636 grape seed proanthocyanidin extract (GSPE) in patients with tissue induration after high-dose radiotherapy for early breast cancer in a double-blind placebo-controlled randomised pha...
Background: Depending on the lung volume in radiotherapy fields, breast cancer radiotherapy has documented side effects on pulmonary function, which can be determined by pulmonary function tests. Central lung distance (CLD), the distance from the chest wall to the edge of the field at the central axis, is an indicator of lung volume within the radiotherapy fields. In this study, we aim to detec...
Introduction: Cancer-related fatigue is one of the most common and debilitating complications of breast cancer. Cancer patients have been found to have lower levels of melatonin, and fatigue has been shown to be correlated with both melatonin and interleukin (IL-6) in cancer patients. This study aimed to evaluate the fatigue and serum level of IL-6 in response to melatonin treatment in breast c...
Background: Bone is one of the most common sites of metastatic disease in malignancies. Many of the cases are asymptomatic and may be diagnosed in primary or secondary follow-up, but in symptomatic cases pain is the prominent symptom which is mostly exaggerated at nights. The improved survival of cancer patients with bony metastases in recent years, specially in breast and prostate cancer, has ...
A retrospective study was undertaken to examine the thyroid cancer cases referred for external radiotherapy to our department during the period of 1991-99. Within this period, a total of 33 patients had been treated by irradiation for thyroid cancer or its metastases and these cases were evaluated for age, sex, pathology and type of surgery. The reason of patients’ referral for external r...
Objective: Radiochromic EBT3 film is a later generation of radiochromic films. The aim of this study is to compare EBT and EBT3 radiochromic films in radiotherapy fields of breast cancer.Methods: A RANDO phantom was irradiated by a 6 MV Siemens Primus linac with medial and lateral fields of radiotherapy of breast cancer. Dosimetry was performed in various points in the fields using EBT and EBT3...
Background: Quantification of radiation-induced apoptosis in peripheral blood lymphocytes (PBLs) has been proposed as a possible screening test for cancer-prone individuals and also for the prediction of normal tissue responses after radiotherapy. Materials and Methods: The neutral version of the comet assay (single-cell gel electrophoresis) was used 24, 48, 72 hours after irradiation ...
Radiotherapy, a highly effective way to destroy breast cancer, causes skin adverse effects. A considerable amount of studies have been conducted to find a way to alleviate or relieve dermal adverse effects of radiation. The aim of this study was to observe the clinical effect of Elaeagnus angustifolia L. cream to treat radiotherapy-induced skin destruction in breast cancer patients. thirt...
