OBJECTIVE The aim of this study was to investigate the effect of 6 and 15-MV photon energies on intensity-modulated radiation therapy (IMRT) prostate cancer treatment plan outcome and to compare the theoretical risks of secondary induced malignancies. METHODS Separate prostate cancer IMRT plans were prepared for 6 and 15-MV beams. Organ-equivalent doses were obtained through thermoluminescent...

BACKGROUND The aim of the study was to examine on the CT basis the inter-application displacement of the positions D0.1cc, D1cc and D2cc of the brachytherapy dose applied to the bladder and rectum of the patients with inoperable cervical cancer. PATIENTS AND METHODS This prospective study included 30 patients with cervical cancer who were treated by concomitant chemo-radiotherapy. HDR intraca...

This retrospective and observational study is based on a review of data from the pathology ledgers and clinical records of the Rand Memorial Hospital, of diagnoses and deaths from cancer from 1988 to 2002 (15 years). The aim was to determine the cancer incidence, mortality, survival rates and the trends for the island of Grand Bahama, Bahamas. The records indicated at least 545 (males: 187; fem...

INTRODUCTION Pathological lesions of the rectum are common and their management requires detailed knowledge of pelvic anatomy. There has been considerable debate as to the definition of the rectum and the variability of the level of the peritoneal reflection. The lack of a clear consensus was proven in the research by McCullen et al. regarding the current pattern of practice for the investigati...

The purpose of this study was to quantify the relationship between treatment time and dose uncertainty due to intrafraction organ motion in prostate cancer radiotherapy (RT). Ten consecutive patients with prostate cancer treated by radical RT by volumetric modulated arc therapy (RapidArc) were considered. For each patient, pre- and post-treatment cone beam computed tomography (CBCT) was perform...

Concurrent chemoradiotherapy is considered the standard treatment for locally advanced cancer cervix (LACC). Radiotherapy commonly administered by a three-dimensional conformal radiotherapy (3DCRT) approach followed brachytherapy (BT). High dose rate (HDR) BT administered; however, several drawbacks exist including invasive technique, pain, requirement of anesthesia, and operative risks. We ass...

BACKGROUND The success of laparoscopic biliary surgery has encouraged application of laparoscopic surgery in colorectal disease. There are some questions regarding laparoscopic colorectal surgery, especially for colorectal cancer. Most important is whether adequate resection of colorectal malignancy can be achieved. A retrospective study was performed to evaluate the pathology of resected speci...

The purpose of this study was to evaluate the performance of a region growing technique for segmenting prostate, bladder and rectum in CT images of prostate cancer patients. Prostate, bladder and rectum were segmented in all CT images of 10 patients using the region growing technique and manual tracing. Volumes of the above organs computed with the region growing technique were compared with th...

The rectum is the site of 30% all colorectal tumours. When contemplating neoadjuvant alternatives and surgical treatments, rectum's position within bony pelvis its closeness to important tissues offer major therapeutic difficulties. Colorectal cancer survival times have improved as a result advances in primary adjuvant treatments. This paper aims investigate tumour regression grade (TRG) rectal...
