adenocarcinomas. Adenosquamous carcinomas with consisting of both glandular and squamous histologic components are a rare malignancy of the colon and rectum. This tumor type was originally described by Herheimer in 1907. Subsequent reports of adenosquamous carcinomas of the rectum and/or colon are limited as the estimated incidence of adenosquamous carcinomas of the colon and rectum is approxim...

  Background and Objectives: To compare pathologic complete response (pCR) in patients with advanced rectal cancer receiving neoadjuvant chemoradiotherapy (NACT) by 5-FU or Xeloda (capecitabine) with and without Eloxatin (oxaloplatin injection). Materials and Methods: Seventy-five consecutive patients with the diagnosis of advanced rectal adenocarcinoma were included. Two basic chemotherapy r...

Background: In the current study the effect of shielded colpostat on rectum received dose was calculated in cervical brachytherapy using Monte Carlo (MC) method. Materials and Methods: Two 60Co sources of GZP6 brachytherapy unit used for intracavitary treatments were simulated using MCNPX Monte Carlo code. Also the two types of colpostats including shielded and unshielded were simulated inside ...

BACKGROUND A knowledge based planning tool has been developed and implemented for prostate VMAT radiotherapy plans providing a target average rectum dose value based on previously achievable values for similar rectum/PTV overlap. The purpose of this planning tool is to highlight sub-optimal clinical plans and to improve plan quality and consistency. METHODS A historical cohort of 97 VMAT pros...

Delivered dose can be calculated by transferring the planned treatment beams onto the daily CBCT. Bladder and rectum volumetric doses were calculated and cor-related to the daily bladder and rectum fullness. Patients for this study underwent hypofractionated prostate IMRT to 70 Gy in 28 fractions. Daily CBCT was utilized for image guidance. A clinically acceptable plan was created using a CTV-t...

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 ...

BACKGROUND During anesthesia, continuous body temperature monitoring is essential, especially in children. Anesthesia can increase the risk of loss of body temperature by three to four times. Hypothermia in children results in increased morbidity and mortality. Since the measurement points of the core body temperature are not easily accessible, near core sites, like rectum, are used. OBJECTIV...

Recently, one of the most pressing issues modern medicine is pelvic floor dysfunction, which includes organ prolapse, urinary and fecal incontinence []. The leading role in maintaining organs assigned to levator ani muscle. study attachment features muscle pelvis, rectum will clarify pathogenesis insufficiency development symptoms prolapse. use classical morphological innovation technologies «A...
