SUMMARY Background Small bowel adenocarcinoma is a rare cancer and consequently the options for clinical
BACKGROUND Chemoradiation for cervical cancer patients is associated with considerable gastrointestinal toxicity. Intensity-modulated radiotherapy (IMRT) has demonstrated superiority in terms of target coverage and normal tissue sparing in comparison to conventional 3D planning in gynaecological malignancies. Whether IMRT in prone (PP) or supine position (SP) might be beneficial for cervical ca...
The purpose of this study was to compare dose reduction to the small bowel and sacral bone by two-field and four-field techniques when the common iliac lymph node region is excluded from the radiation field in external beam radiotherapy of uterine cervical cancer. Thirteen patients with cervical cancer were entered into the study. Conventional treatment plans based on bony landmarks were made w...
Unusually early presentation of small-bowel adenocarcinoma in a patient with Peutz-Jeghers syndrome.
Peutz-Jeghers syndrome (PJS) is an autosomal dominant cancer predisposition syndrome characterized by melanotic macules and hamartomatous polyps. Small-bowel surveillance in the pediatric PJS population is not designed to identify small-bowel malignancy, which is thought to arise in adulthood. A 13-year-old boy presented with lead-point intussusception, requiring emergent surgical resection. A ...
BACKGROUND AND PURPOSE To compare organ-at-risk doses and setup reproducibility using the prone and supine orientations in volumetric modulated arc therapy (VMAT) for rectal cancer. MATERIALS AND METHODS Seventeen consecutive rectal cancer patients undergoing preoperative radiation were selected and setup in either the prone (N = 8) or supine (N = 9) position. All patients were treated using ...
INTRODUCTION Uterine leiomyosarcomas are relatively uncommon soft tissue neoplasms and rarely metastases to small bowel. In the current case; a patient is suffering from intestinal perforation due to metastatic leiomyosarcoma of the small bowel. CASE PRESENTATION A 59-year-old woman underwent a modified radical mastectomy for infiltrating ductal cancer of the breast six years ago and a total ...
Background : Mechanical obstruction is the most common surgical disease of the small intestine , which can be potentially fatal . However appendicitis is very rare cause of intestinal obstruction and is usually . In rare cases of appendicitis, symptoms of small intestine obstruction can be more predominant than the appendicitis symptoms . This may lead to delayed diagnosis of appendicitis and...
The purpose of this study is to evaluate dose-volume histogram (DVH) predictors for the development of chronic gastrointestinal (GI) complications in patients with cervical cancer who have undergone postoperative concurrent chemotherapy and whole-pelvic radiation therapy (WPRT). The subjects were 135 patients who had undergone postoperative WPRT with concurrent nedaplatin-based chemotherapy bet...
