To determine the maximum tolerated dose (MTD) of AZD6244 or AZD2171 when combined with pre-operative capecitabine and radiotherapy in patients with locally advanced rectal cancer.
The best curative resection rates reported for patients with operable rectal cancer treated with standard chemoradiotherapy are approximately 50-60%.The pathological complete response rates are only 10-20%. Therefore, there is a need for more effective treatment. In this trial we will evaluate the combination of chemoradiotherapy with either a VEGFR (vascular endothelial growth factor receptor) or MEK (MAP Kinase)inhibitor.
1. Define the tolerability, MTD (maximum tolerated dose) and DLT (dose limiting toxicities) of chemoradiotherapy in combination with
- cediranib, a VEGF receptor tyrosine kinase inhibitor that inhibits angiogenesis or
- AZD6244, a potent MEK inhibitor that inhibits cell proliferation
2. Define a dose suitable for phase II evaluation
3. Test the impact of the combination on soluble and imaging (FLT-PET and DCEMRI/DWI) biomarkers to guide their use in phase II testing Summary Patients will receive standard chemoradiotherapy plus ascending doses of AZD6244 or cediranib from day -10 (relative to start of chemoradiotherapy) to day 35. If feasible, patients' tumours will be resected 10-12 weeks after treatment. Translational studies on available tissue and blood will be performed and DCE-MRI/DWI and FLT-PET will be carried out on 5 patients in the expanded cohort for AZD6244 (FLT-PET and DCE-MRI) and 5 patients in the expanded cohort for cediranib (DCE-MRI).
Cohorts Cediranib - 15mg od, 20mg od and 30mg od AZD6244 - 50mg bd and 75mg bd

Cediranib is being tested to assess its effectiveness on the growth of kidney cancer tumours and also how well it is tolerated.
To determine how patients with advanced cancer and various degrees of hepatic impairment will metabolise Cediranib.
This study is being carried out to see how single and multiple doses of cediranib are handled by the body (that is how they are absorbed, broken down and got rid of from the body) by measu...
Phase I, open study to assess the effect of ketoconazole, a marketed drug, on the way the body handles the experimental drug cediranib, in patients with advanced cancer.

Tumors or cancer of the RECTUM.
A cancer registry mandated under the National Cancer Act of 1971 to operate and maintain a population-based cancer reporting system, reporting periodically estimates of cancer incidence and mortality in the United States. The Surveillance, Epidemiology, and End Results (SEER) Program is a continuing project of the National Cancer Institute of the National Institutes of Health. Among its goals, in addition to assembling and reporting cancer statistics, are the monitoring of annual cancer incident trends and the promoting of studies designed to identify factors amenable to cancer control interventions. (From National Cancer Institute, NIH Publication No. 91-3074, October 1990)
A compound tubular gland, located around the eyes and nasal passages in marine animals and birds, the physiology of which figures in water-electrolyte balance. The Pekin duck serves as a common research animal in salt gland studies. A rectal gland or rectal salt gland in the dogfish shark is attached at the junction of the intestine and cloaca and aids the kidneys in removing excess salts from the blood.

Protrusion of the rectal mucous membrane through the anus. There are various degrees: incomplete with no displacement of the anal sphincter muscle; complete with displacement of the anal sphincter muscle; complete with no displacement of the anal sphincter muscle but with herniation of the bowel; and internal complete with rectosigmoid or upper rectum intussusception into the lower rectum.
