PURPOSE We used data from the first large-scale overwhelmingly population-based study (a) to quantify the risk of adverse pregnancy outcomes in survivors of childhood cancer in relation to cancer type and treatment and (b) to assess live birth rates relative to the general population. METHODS A questionnaire, including questions inquiring about pregnancy outcomes, was completed by 10,483 surv...

To minimize renal radiation in abdomical radiotherapy, shielding of the kidneys is essential. IVP-simulator is used as an standard method. In this study, we used 99mTc-DMSA to localize and shield the Kidneys and we compared this method with IVP-simulator. The size of the kidneys was proven to be larger as compared with IVP method. The mean of the overlap percentage was 81.88 in right and ...

Patient respiratory motion is a major problem during external beam radiotherapy of the thoracic and abdominal regions due to the associated organ and target motion. In addition, such motion introduces uncertainty in both radiotherapy planning and delivery and may potentially vary between the planning and delivery sessions. The aim of this work is to examine subject-specific external respiratory...

Background: We analyzed local regional recurrence patterns of thoracic esophageal carcinoma after three-field lymph node dissection (3-FLD) with and without postoperative radiotherapy, assessed the radiation value for control. Methods: The study reviewed 239 recurrences squamous cell 3-FLD from 2010 to 2018 in our hospital, retrospectively, compared between sur...

Present study was designed to evaluate potential risks and benefits of adjuvant radiotherapy in selected patients with intermediate-risk endometrial cancer. A total of 100 patients with stage IB grade II endometrial cancer followed up in Radiation Oncology Clinic at Dr. Lutfi Kirdar Training and Research Hospital were evaluated retrospectively to determine the influence of postsurgical adjuvant...

In a repeated radiotherapy owing to a local recurrence close to the previous irradiation, the dose distribution of next irradiation is required to avoid overlap with previous one. Therefore, a system for displaying dose-distribution image of previous irradiation on a present anatomical image would be helpful in designing new radiotherapy. However, registration of two abdominal CT images acquire...

We present a case of a 61-year-old male presenting with post-prandial epigastric pain and marked weight loss. Investigation revealed calcific atherosclerosis of the abdominal aorta, coeliac axis, superior mesenteric (SMA) and renal arteries. He had undergone radiotherapy for testicular teratoma 34 years previously. Percutaneous mesenteric revascularization by primary stenting of the SMA proved ...

Background Conventional radiotherapy for painful spinal metastases can be delivered with a single posterior-anterior (PA) or two opposed anterior-posterior (APPA) fields. We studied the effectiveness and toxicity of both techniques and studied whether treatment technique was predictive for abdominal and skin toxicity. Patients and methods Within the Dutch Bone Metastasis Study, 343 patients r...
