BACKGROUND The purpose of this study was to compare the change in depth of target volume and dosimetric parameters between the supine and lateral decubitus positions for breast boost treatment with electron beam therapy. METHODS We analyzed 45 patients who were treated, between 2009-2010, with whole breast radiation (WBRT) followed by a tumor bed boost in the lateral decubitius position. Tumo...

An in vivo biosensor is a technology in development that will assess the biological activity of cancers to individualise external beam radiotherapy. Inserting such technology into the human body creates cybernetic organisms; a cyborg that is a human-machine hybrid. There is a gap in knowledge relating to patient willingness to allow automated technology to be embedded and to become cyborg. Ther...

Androgen deprivation therapy (ADT) has been used in the management of prostate cancer for more than four decades. Initially, hormone therapy was given largely for palliation of symptomatic metastases. Following several randomized trials of patients with intermediate- to high-risk prostate cancer that demonstrated improvements in biochemical control and survival with the addition of ADT to exter...

In this paper, we introduce a concept in personal robotics to support independent living for people with disabilities. Specifically, we introduce our current efforts on object retrieval and physical therapies for stroke rehabilitation. Our major contributions are as follows: general-purpose personal robots that can potentially deliver many kinds of services; methods of conveying goals to the ro...

BACKGROUND Biochemical control from series in which radical prostatectomy is performed for patients with unfavorable prostate cancer and/or low dose external beam radiation therapy are given remains suboptimal.The treatment regimen of HDR brachytherapy and external beam radiotherapy is a safe and very effective treatment for patients with high risk localized prostate cancer with excellent bioch...

OBJECTIVE The objective was to analyze the outcomes of the patients, who received salvage radiotherapy for incidentally discovered cervical cancer following simple hysterectomy, and to identify the influence of intracavitary radiotherapy on treatment outcomes. METHODS Data from 117 patients with occult cervical cancer who underwent simple hysterectomy followed by salvage radiotherapy from Sep...

Introduction Wedge modifiers are commonly applied in external beam radiotherapy to change the dose distribution corresponding to the body contour and to obtain a uniform dose distribution within the target volume. Since the radiation dose delivered to the target must be within ±5% of the prescribed dose, accurate dose calculation by a treatment planning system (TPS) is important. The objective ...

Reported doses of external beam radiotherapy and radioimmunotherapy (RIT) to produce equivalent therapeutic effects are inconsistent, with many proposed causes. Calculations of effective dose were performed for the case of LS174T human colon cancer xenografts, where a 60Co single fraction exposure (6 Gy) was matched with 131I-labeled 17-1A monoclonal antibody therapy (300 microCi injection, 19 ...

Metastasis to the breast from an extramammary malignant neoplasm, including esthesioneuroblastoma, is uncommon. The present study describes a rare case of sinonasal esthesioneuroblastoma, Hyams' histologic grade 2, Kadish's stage C, T4N0M0, in a 30-year-old female. The patient underwent a radical ethmoidectomy with external beam radiotherapy, followed by chemotherapy including five cycles of ci...

Cancer incidence and mortality depend on a number of factors, including age, socio-economic status and geographical location, and its prevalence is growing around the world. Most of cancer treatments include external beam radiotherapy or brachytherapy. Brachytherapy, a type of radiotherapy with energy from radionuclides inserted directly into the tumor, is increasingly used in cancer treatment....
