introduction: in spite of large number of studies regarding relation between thyroid cancer and childhood irradiation, contraversy still exists management of these patients. this study tries to find optimal method of thyroid evaluation in this group. methods and patients: in a recall program using mass media in khorasan, all patients with childhood irradiation were invited for thyroid evaluatio...

BACKGROUND Evidence shows ionizing radiation can cause lung cancer, but few studies have quantified risk in relation to radiation dose. PURPOSE This study evaluated the long-term risk of lung cancer among women treated with radiation for breast cancer. METHODS In this case-referent study, the Connecticut Tumor Registry was used to identify women diagnosed with histologically confirmed invas...

BACKGROUND Lymphedema is the major complication following breast cancer treatment and can persist long periods of time and affect breast cancer survivors' quality of life. Accurate estimation of the risk factors for lymphedema is of significant importance. In this article we report the factors for secondary lymphedema among postmenopausal breast cancer patients after radical mastectomy in China...

In well-selected patients who choose to pursue breast conservation therapy (BCT) for early-stage breast cancer, partial breast irradiation (PBI) delivered externally or intraoperatively, may be a viable alternative to conventional whole breast irradiation. Two large, contemporary randomized trials have demonstrated breast intraoperative radiotherapy (IORT) to be noninferior to whole breast exte...

background: to reduce the dose to normal tissues surrounding the treated breast, a uniform magnetic field was used within a humanoid phantom in breast radiotherapy. materials and methods: monte carlo simulations were performed with geant4, irradiating humanoid phantoms in a magnetic field. to reconstruct phantoms, computed tomography (ct) data slices of four patients were used for the monte car...

Background: This two-arm, randomized clinical study aimed to compare efficacy between topical Alpha ointment and topical hydrocortisone cream (1%) in the healing of radiation-induced dermatitis in breast cancer patients. Methods: The inclusion criteria comprised newly pathologically proven, locally advanced breast cancer (treated with modified radical mastectomy followed by sequential adjuvant ...

BACKGROUND Metastases to the thyroid are rare. The most common primary cancer to metastasize to the thyroid is renal cell carcinoma, followed by malignancies of the gastrointestinal tract, lungs, and skin, with breast cancer metastases to the thyroid being rare. Overall, the outcomes in malignancies that have metastasized to the thyroid are poor. There are no prospective studies addressing the ...

Background: Intensity Modulated Radiotherapy (IMRT) can improve radiotherapy (RT) results by improving healthy tissue sparing. Additionally, IMRT provides more consistent dose deliveries and suppresses secondary tumor formation. RT is a principal treatment in breast cancer (BC). Aim: To evaluate the outcome of the Radiotherapy Plans (RTP) that use IMRT technique to left breast and other organs,...

Radiotherapy is an essential part of the multimodality treatment of breast cancer. Applying safe and effective treatment requires appropriate facilities, staff, and equipment, as well as support systems, initiation of treatment without undue delay, geographic accessibility, and completion of radiotherapy without undue prolongation of the overall treatment time. Radiotherapy can be delivered wit...
