Filter by:The objective of this study is to investigate whether the use of Human Peritoneal Membrane (HPM) in a temporary loop ileostomy is beneficial to patients. Benefit will be defined, for purposes of this study, as a decrease in adhesions resulting in decreased operative time during ileostomy closure, with promotion of peritoneal remodeling.
This phase II trial is studying how well giving azacitidine together with entinostat works in treating patients with metastatic colorectal cancer. Drugs used in chemotherapy, such as azacitidine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Entinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving azacitidine together with entinostat may kill more tumor cells.
This is a single centre pilot trial to establish the feasibility and role of endoluminal HIFU in patients with locally advanced cancer within the pelvis that is either primary or recurrent and with all available current therapy inappropriate and/or exhausted. The aim is to make a preliminary assessment of efficacy & dosage for evaluation in a randomised controlled trial. Whilst efficacy data are limited in a small feasibility study; radiological, biochemical and histopathological analysis of the patient and patient specimens, along with quality of life questionnaires (QoL), will be used to provide preliminary measures of efficacy in this patient cohort. These analyses will allow examination of the biochemical, metabolomic and histological changes associated with HIFU treatment in cancer within the pelvis.
Neoadjuvant chemoradiotherapy (CRT) has been the standard therapy for local advanced rectal cancer. Pathological complete response (pCR) is an important prognostic factor for local control and survival. A high intensity CRT increases not only the pCR rate, but also toxicity, especially diarrhea. Compared with traditional RT technique, intensity-modified radiation therapy (IMRT) can decrease the toxicity of diarrhea because of low volume of high dose for small bowel. Therefore, IMRT technique provides an opportunity to improve the dose intensity of neoadjuvant CRT. The investigators hypothesize that a higher treatment dose induces a high rate of pCR and design a two-arm trial. in this trial, low intensity CRT includes the whole pelvic irradiation of 50Gy together with Oxaliplatin and Capecitabine weekly. While in high intensity group, additional concomitant 5Gy for primary tumor and a cycle of Xelox are prescribed. All patients will receive a total mesorectal excision (TME) 8 weeks after CRT.
To determine if short course radiotherapy followed by chemotherapy can maintain morbidity at or below levels reported with concurrent 5FU, oxaliplatin, and radiotherapy, while maintaining response rates comparable to what would be expected with radiotherapy and concurrent chemotherapy.
After resection of diseased segments of the large intestine, the continuity of the intestine has to be restored. This can be done by suturing or with so called stapling devices. In addition since 2 centuries compression rings are used to connect the intestine after resection. The NITICAR27 device is a novel compression anastomosis device. The investigators want to prove if this novel device can be compared to commonly used stapling devices concerning anastomotic leakage, bleeding and stenosis.
The objective of Timing and Deferral of Rectal Surgery Following a Continued Response to Pre-operative CRT study is to establish the time to maximum tumour response following CRT, and to investigate whether surgery can be safely avoided within the tight framework of the trial follow-up protocol in a small group of patients where the cancer becomes undetectable by imaging modalities.
Follow-up programmes consume a large amount of resources with less time for the surgeon to take on new patients. The aim of this randomised study was to compare patient satisfaction, resource utilisation, and medical safety in patients curatively operated for rectal cancer that were followed-up by a surgeon or a nurse.
The purpose of the study is to evaluate the efficacy and safety of the combination of capecitabine + bevacizumab concomitantly with radiotherapy versus capecitabine concomitantly with radiotherapy, as neoadjuvant treatment for patients with localized and resectable rectal cancer.
RATIONALE: PD 0332991 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. PURPOSE: This phase II trial is studying the side effects and how well PD 0332991 works in treating patients with refractory solid tumors.
