ISRCTN - ISRCTN54531450: Study with intensity modulated radiation therapy with cisplatin to treat stage I-IVA cervical cancer

Plain English Summary

Background and study aims
Cervical cancer is a leading cause of death by cancer in women. Despite the successes of screening and vaccination, a large proportion of women dont take preventative steps and are diagnosed with locally advanced stages of cancer. Concurrent chemotherapy and radiation therapy (RT) is the standard treatment for patients in addition to standard cisplatin-based chemotherapy. When patients received this combination treatment, there are side effects and sometimes the cancer returns. Therefore, strategies to reduce the side effects and allow treatment intensification are needed. Conventional pelvic RT results in a box-shaped radiation dose to the pelvis that covers both tumor tissues and normal tissues. Intensity modulated radiation therapy (IMRT) is a modern RT technique that differs from conventional techniques in many ways. First, patients undergo computed tomography (CT) simulation so that customized radiation doses can be delivered. IMRT treatment planning involves multiple beam angles and uses computerized treatment planning to reduce radiation to surrounding normal tissues. This would be the first international study to test IMRT for both postoperative and definitive treatment of cervical cancer.

Who can participate?
Patients with cervical cancer (invasive squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma) will be enrolled in the study.

What does the study involve?
After signing an informed consent form, patients will receive radiation therapy daily (Monday to Friday) for 5 to 5½ weeks. Once a week on study days 1, 8, 15, 22, and 29 patients will also receive intravenous infusions of cisplatin prior to radiation therapy. In addition, once a week some evaluations and tests will be done. After chemotherapy and radiation is complete patients will be followed up at the following times: 1 week, 2 weeks, 1, 2, 4, 8, 12, 18, 24, 30, and 36 months. The assessments at these visits will be part of the patients routine care for their cancer and will include a physical examination, review of side effects, testing and a quality of life evaluation.

What are the possible benefits and risks of participating?
Standard treatment for cervical cancer may involve risks and discomforts. Patients will be at risk for side effects whether or not you choose to participate in this study. There may also be other side effects that we cannot predict. Medicines and other treatments can be given to make the side effects less serious and uncomfortable. Many side effects go away shortly, but in some cases, side effects may be serious, long-lasting, and may even cause death.
Patients participating in this study may receive a direct medical benefit. IMRT reduces radiation doses to normal organs and tissues, which previous studies have indicated may reduce side effects compared to standard radiation therapy. However, the benefits of IMRT are unknown. Others may also benefit from the information learned from this research study.

Where is the study run from?
The University of California, San Diego Moores Cancer Center is coordinating the study between approximately 14 countries and 25 sites.

When is the study starting and how long is it expected to run for?
Patient enrollment started in September 2011 and is expected to continue until December 2014.
