Nephron-sparing surgery is currently the standard of care for the management of small renal masses. While both neoadjuvant and adjuvant conventional external beam radiotherapy have failed to demonstrate an oncologic benefit for the treatment of renal cell carcinoma, more recent work aims to explore the utility of stereotactic radiotherapy. We present the case of a 70-year-old woman who failed ...
BACKGROUND Intraoperative radiotherapy (IORT) is promising approach that is being tested in randomised clinical trials. In the Targit (TARGeted Intraopeartive radioTherapy) trial IORT can be delivered at the time of primary surgery or as a second procedure. Patients prefer the single procedure of intraoperative radiotherapy even if it is under general anaesthetic to 6-weeks of daily visits for ...
External Beam Radiotherapy (EBRT) remains the mainstay for radical treatments, in malignancies in head and neck regions. Teletherapy with cobalt-60 isotope machines are still available for cancer management in countries with more population, and their continuation as a basic machine has been recommended [1]. With linear accelerators, the present day radiotherapy for radical treatments in head a...
BACKGROUND Painful plantar heel spur (PPHS) is a benign disorder with painful heels as a result of plantar calcaneal bone spur. Exact etiological factors are still unclear. Treatment typically consists of osteoarthritis tretment schedules and surgical techniques. External radiotherapy is another treatment option. This study is aimed to determine effectiveness and treatment outcomes of external ...
BACKGROUND This study was designed to evaluate the integral dose (ID) received by normal tissue from intensity-modulated radiotherapy (IMRT) for prostate cancer. METHODS AND MATERIALS Twenty-five radiation treatment plans including IMRT using a conventional linac with both 6 MV (6MV-IMRT) and 20 MV (20MV-IMRT), as well as three-dimensional conformal radiotherapy (3DCRT) using 6 MV (6MV-3DCRT)...
Brachytherapy is not widely used in Sweden to treat localized prostate cancer. This treatment method has been available for some time, but recent advancements in technology are leading to increased utilization. Findings from isolated, uncontrolled studies of high dose rate brachytherapy in combination with external beam radiotherapy suggest some improvement in treatment outcomes. However, prosp...
PURPOSE This randomized, prospective study assesses the impact of postoperative external-beam radiation therapy on local recurrence (LR), overall survival (OS), and quality of life after limb-sparing resection of extremity sarcomas. PATIENTS AND METHODS Patients with extremity tumors and a limb-sparing surgical option were randomized to receive or not receive postoperative adjuvant external-b...
Cancer, which is the uncontrolled division of cells, a leading fatal disease in world with high mortality rates. It can be treated using several methods, including radiotherapy, involves ionizing radiation. Radiotherapy on basis source placement has two types, i.e. brachytherapy and external beam radiotherapy. External radiotherapy evolved from 2-D conventional therapy to 3-D Conformal (3D-CRT)...
OBJECTIVES The aim of the study was to estimate acute and late complications of radiation therapy in primary invasive vaginal carcinoma (PIVC) patients. MATERIAL AND METHODS The analysis was performed for the group of 152 PIVC patients given radical radiotherapy in the Krakow Branch of Centre of Oncology during the 1967-2005 period. Twenty five (16.5%) patients in I stage with primary tumour ...
Prostate cancer incidence is rising due to the ageing population and increased public and doctor awareness. The role of screening is still not clear due to the large number of asymptomatic men who would need to be screened and treated to prevent one death. Discussion of all treatment options should be undertaken, with the patient having the opportunity to meet a clinical oncologist and urologic...
