In cervix cancer tumor oxygen levels and fluid pressure in the tumor have been shown to be related to patient outcome. Analysis of the way tumors enhance after intravenous contrast injection using MRI and CT can be used to determine parameters that relate to tumor blood vessels. In this study we hope to determine if there is a relationship between the enhancement of cervix cancer on MRI and CT and tumor oxygen levels and interstitial fluid pressure. If such a relationship exists then it could help improve the care of patients wiht cervix cancer by allowing for more aggressive therapy of patients with cancer that have more ominous imaging characteristics
Radiation therapy still remains mainstay of treatment for patients with carcinoma cervix in advanced stages. Conventional treatment with radiation therapy includes a combination of external beam radiation therapy and intracavitary treatment. Low dose rate intracavitary brachytherapy treatment is the time-tested modality of brachytherapy with sound radiobiological bases. But high dose rate brachytherapy is a relatively new alternative. In low dose rate brachytherapy the staff receives some radiation while in the high dose rate brachytherapy procedure complete protection to staff can be achieved as the treatment is done with remote afterloading technique. The high dose rate brachytherapy is possible as Out Patient Department procedure. Few clinical trials have proven the feasibility and efficacy of high dose rate brachytherapy in carcinoma of cervix. However, there is no concrete evidence especially in developing countries for the change of practice to HDR brachytherapy. Hence, at Tata Memorial Hospital with an aim to assess the efficacy, feasibility, early and late complications of high dose rate brachytherapy in contrast with low dose rate brachytherapy we propose this study.
The purpose of this study is to investigate the effect of certain variables such as the fullness of the patients bladder and the position of the treatment applicator on the dose of radiation that other organs such as the bladder and the rectum receive during radiation treatment for endometrial carcinoma.
Patients with more advanced stages of cervix cancer are treated by radiotherapy. Overall, more than 50% are cured. Approximately half of those patients not cured have current cancer in the irradiated volume. Higher doses of radiation would be expected to cure more patients. To give high doses of radiation safely, the investigators need to know very precisely where the cancer is and then they can use new technology available at the Cross Cancer Institute (tomotherapy) to target the cancer precisely, giving higher doses to the cancerous tissues and lower doses to the non-cancerous tissues. This study of ten patients with cervical cancer will investigate the added value of MRI scanning on precise tumor definition to facilitate more accurate radiotherapy treatment planning. For this study, patients will be treated in the conventional way with conventional doses. The investigators hope that treatment for future patients will be planned with MRI data and that they will be treated to higher doses of tomotherapy.
The Cross Cancer Institute has recently acquired a tomotherapy radiotherapy treatment machine; the first of its kind in Canada. It has the potential to improve cancer treatment outcomes where radiotherapy is used. Cervix cancer is a disease where radiotherapy is a particularly important treatment modality. The researchers believe that by combining tomotherapy (which has the ability to give higher doses of radiation to areas of cancer while sparing normal tissues) with radiotherapy given from inside the uterus and vagina (brachytherapy) disease outcomes will be improved. For this to be possible the researchers will need to accurately map the doses of radiation given to the cervix, uterus and other pelvic organs from these two types of radiation treatment. As well as being used for treatment, the tomotherapy machine can also be used for taking medical images by using very much lower doses of radiation. This study will allow the researchers to develop the mapping process by using very low doses of radiation on the tomotherapy unit to take medical x-ray images of patients being treated by brachytherapy for cervix cancer. In this special circumstance the researchers expect the images to be of a higher quality than for conventional computed tomography (CT) scanning or magnetic resonance imaging (MRI) scanning.
The purpose of this trial is to study clinical effects of two/four high dose rate (HDR) brachytherapy applications and teletherapy with or without weekly cisplatin in cervix cancer.
