简要总结
The purpose of this trial is to improve the clinical management and outcome of patients with locally advanced cervical cancer by using positron emission tomography-computed tomography (PET-CT) imaging.
There is considerable debate worldwide regarding the utility of PET for staging cervical cancer. Although there are studies on the accuracy (sensitivity and specificity) of PET in cervical cancer, there are currently no prospective randomized studies on how PET information affects treatment decisions and outcomes.
详细描述
Cervical cancer is the second most common cause of cancer deaths worldwide. In Canada, it is estimated that in 2009 there will be 1,300 new cases of cervical cancer and that 380 women will die of this disease. The corresponding 2009 data for Ontario is 500 new cases and 140 deaths. In Canada, cervical cancer screening with the Pap test allows for the diagnosis and curative treatment of precancerous lesions of the cervix or early cervical cancers. Symptoms of cervical cancer include vaginal bleeding and discharge. Unfortunately these are often associated with more advanced disease.
The costs associated with health care are increasing. PET is an expensive imaging modality. Given that resources for health care are not unlimited, there needs to be high quality evidence of an intervention such as PET's efficacy.
