Filter by:The objective of the study is to provide proof that a MRI based preoperative radiochemotherapy in patients with locally advanced rectal carcinoma allows limiting RCT to high risk patients without increase of locoregional recurrence rate and decrease of overall survival provided there is a high quality of mesorectal excision.
A Pilot Trial of Pre-Operative Chemoradiotherapy Using Capecitabine (Xelodaâ), External Beam Radiation and Cetuximab (Erbitux®) Followed by Definitive Surgery in Patients With Localized (Non-Metastatic) Rectal Cancer
The standard treatment of rectal adenocarcinoma is total mesorectal excision (TME). The technique involves a low anterior rectal or colo-anal resection, very often associated with a protective stoma or abdominal-perineal resection with permanent colostomy. Transanal endoscopic microsurgery (TEM) allows access to tumors up to 20 cm from the anal margin, with minimal postoperative morbidity and mortality. Recent studies of T1 rectal adenocarcinomas consider TEM to be the technique of choice. However the treatment of T2 rectal cancers remains controversial. Chemotherapy and radiotherapy (CT/RT) has achieved a concomitant reduction in local recurrence and an increase in survival. Hypothesis: Patients with rectal adenocarcinoma less than 10 cm from the anal margin and up to 4 cm in size, staged after endorectal ultrasound and MRI as T2 or superficial T3 N0-M0-N0-M0, who underwent surgery after preoperative local chemoradiotherapy (TEM), achieve effective results in terms of local recurrence similar to radical surgery (TME). OBJECTIVES: Primary: To compare the results of local recurrence at 2 years in patients treated with preoperative chemoradiotherapy and TEM and in patients treated with conventional radical surgery (TME). Secondary: To analyse the 3-year survival results in patients treated with CT/RT. Methodology: Multicenter clinical trial in a calculated sample of 173 patients.
The aim of the project is to evaluate the oncological and functional outcome of the more extensive perineal dissection - i.e the extra levator resection - in abdominoperineal resections in patients with rectal cancer. Hypothesis: Extra levator perineal resection reduces local recurrence three year postoperatively compared to traditional abdominoperineal resection and improves QoL 2-4 years postoperatively.
The study will determine the maximum tolerated dose (MTD) of AUY922 given in combination with cetuximab in previously treated patients with KRAS wild-type metastatic colorectal cancer.
This study combines midostaurin (PKC412) with radiation and a standard chemotherapy drug call 5-Fluorouracil (5-FU) for subjects with advanced rectal cancer. Midostaurin is a type of kinase inhibitor which works by blocking proteins associated with cancer cell growth. Previous studies also suggest that midostaurin may help increase the effectiveness of radiation therapy. In this research we are looking for the highest dose of midostaurin that can be given safely in combination with standard chemoradiation.
This study is proposed to evaluate whether giving part of the chemotherapy prior to radiotherapy and surgery (as opposed to standard of care, which involves giving all the chemotherapy after radiotherapy and surgery) for patients with node positive operable rectal cancer will result in higher patient compliance to chemotherapy.
In the Netherlands approximately 2300 new patients are diagnosed with rectal cancer each year. Standard treatment for patients with a T2 or T3 rectal cancer consists of preoperative short course of radiotherapy followed by surgery. In advanced cases long course of radiotherapy combined with chemotherapy is used instead of a short cause. In some of these advanced cases a complete remission is observed after a long course of radio-/chemotherapy. Patients who respond well to neo-adjuvant treatment carry a better prognosis. Objective of this research is to evaluate whether neo-adjuvant chemo-/radiotherapy in small non-advanced rectal cancers can be used to obtain a complete or near complete remission. In these patients could a complete resection of the rectum as an organ be avoided by treating them with a local excision with the TEM-technique (Transanal Endoscopic Microsurgery) of the scar. The advantage for these patients is, that they do not need major abdominal surgery and in a substantial number of these patients the rectum can be preserved with a better function of continence.
After rectal excision, the rate of anastomotic leak and abscess is higher than after colic surgery. In order to limit and avoid the risk of pelvic sepsis after rectal excision, a prophylactic pelvic drainage is usually used. If current data have confirmed the uselessness of drainage in colic surgery, the question stay in abeyance in rectal surgery. This practice had never been evaluated in patients with rectal excision and low anastomosis (patients with a high risk of pelvic sepsis)
The purpose of this study is the increase of resection rate of primary cancer in rectal after short course radiotherapy without interrupt chemotherapy schedule during the period of chemotherapy. The subject should have the pathologically confirmed for unresectable (impossible to try Total mesorectal excision) rectal cancer with liver metastasis. This trial contributes to save the time for decreasing primary tumor in rectal and metastasis cancer to whole body after short course radiotherapy.
