BACKGROUND Studies of complications resulting from surgery or radiotherapy for prostate cancer have mainly focused on incontinence and erectile dysfunction. We aimed to assess other important complications associated with these treatments for prostate cancer. METHODS We did a population-based retrospective cohort study, in which we used administrative hospital data, physician billing codes, a...

  Rectal cancer is the second most common cancer in large intestine. The prevalence and the number of young patients diagnosed with rectal cancer have made it as one of the major health problems in the world. With regard to the improved access to and use of modern screening tools, a number of new cases are diagnosed each year. Considering the location of the rectum and its adjacent organs, ma...

nodes even in the same category of T3 cancer in patients without radiation therapy. The distal resection margin (DRM) means the length of the tumor-free normal mucosa and rectal wall. Han et al. [3] published the manuscript, ‘Association between a close distal resection margin and recurrence after sphincter-saving resections for T3 midor low-rectal cancer without radiotherapy.’ With retrospecti...

Cancer incidence rates from the Hong Kong Cancer Registry show significant increases in lung and colon cancers and decreases in nasopharyngeal cancer in both sexes from 1973 to 1992. Moreover, cervical cancer and male esophageal cancer have declined significantly, and changes in the trends of cancer of the following sites were of borderline significance: decreasing male laryngeal and female eso...

This study investigates the dosimetry and radiobiological model variation when a second photon arc was added to prostate volumetric-modulated arc therapy (VMAT) using the single-arc technique. Dosimetry and radiobiological model comparison between the single-arc and double-arc prostate VMAT plans were performed on five patients with prostate volumes ranging from 29-68.1 cm3. The prescription do...

Cancer is the second leading cause of death during the reproductive years, but the incidence during pregnancy is low. The incidence of cancer of the rectum during pregnancy is very rare (1:50,000 to 1:100,000 pregnancies). Usually, the symptoms of this type of cancer are nonspecific and sometimes they are confused with normal changes of pregnancy. The diagnosis of rectal cancer is usually made ...

BACKGROUND Gastrointestinal (GI) toxicity is a common effect following radiation therapy (RT) for prostate cancer. Purpose of the present work is to compare two Normal Tissue Complication Probability (NTCP) modelling approaches for prediction of late radio-induced GI toxicity after prostate external beam radiotherapy. METHODS The study includes 84 prostate cancer patients evaluated for late r...

PURPOSE The purpose of the present study was to quantify the inter-fractional motion of the rectum and the rectal and bladder volumes using CBCT scans taken during chemoradiation therapy (CRT) for rectal cancer. Also, assessment was made for a better margin for simultaneous integrated boost - intensity modulated radiation therapy (SIB-IMRT) for rectal cancer. METHODS AND MATERIALS There were ...

methods study on 34 patients diagnosed with rectal adenocarcinoma referred to oncology clinic was conducted. the treatment plan included 4050 cgy radiotherapy and 5fu, xeloda chemotherapy. all patients were assessed with 1/5 t mri 6 to 8 weeks after treatment. t1 and t2 images with sagittal, cronal and axial planes with and without contrast agent were obtained and interpreted by two radiologist...
