This study will investigate short course radiation therapy using IMRT as an alternative to standard chemo radiation because prior studies have shown that this method of treatment will potentially reduce some fo the side effects of standard treatment, improve quality of life, and help to control the growth of rectal cancer cells. IMRT is a type of radiation that uses computer-generated images to match radiation to the size and shape of the tumor. Since the intensity of each radiation beam can be controlled, the radiation dose can wrap around normal tissue which allows the study doctor to deliver a higher dose of radiation to the tumor with less damage to nearby healthy tissue. The purpose of this research study is to see what impact this treatment will have on quality of life, as well as to see if there are any late side effects that come about after the participant has completed the treatment.
- Radiation treatment to the rectum will be given once a day, for 5 days. Each radiation treatment will take about 20-30 minutes.
- The following procedures will be performed on day 1 of radiation treatment: physical examination, blood tests and quality of life questionnaire.
- During radiation treatment a physical examination will be performed once during the 5 days of radiation treatment. A Quality of Life Questionnaire will be administered on the last day of radiation treatment.
- Surgery will be performed within 3-14 days after the last day of radiation treatment.

The objective is to report outcomes,including grade ≥2 overall late rectal and urinary toxicity and biochemical control rates in patients treated with IMRT (70 gy, 74 Gy and 80 Gy)

One of the late complications associated with radiation therapy (RT) is a possible increased risk of second cancer. In this systematic review, we analysed the incidence of rectal cancer following prim...
CONFORMAL RADIOTHERAPY that combines several intensity-modulated beams to provide improved dose homogeneity and highly conformal dose distributions.
Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.
Drug therapy given to augment or stimulate some other form of treatment such as surgery or radiation therapy. Adjuvant chemotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.
Organs which might be damaged during exposure to a toxin or to some form of therapy. It most frequently refers to healthy organs located in the radiation field during radiation therapy.
Drugs used to protect against ionizing radiation. They are usually of interest for use in radiation therapy but have been considered for other, e.g. military, purposes.
Cancer is not just one disease but many diseases. There are more than 100 different types of cancer. Most cancers are named for the organ or type of cell in which they start - for example, cancer that begins in the colon is called colon cancer; cancer th...
