mri and ct scans to evaluate invasive cervical cancer before treating patients

Conditions: Cervical Cancer

Summary: rationale: imaging procedures such as mri or ct scans may improve the ability to detect cervical cancer and determine the extent of disease. purpose: diagnostic trial to determine the effectiveness of mri and ct scans in evaluating invasive cervical cancer before treatment of patients.

objectives: * compare the diagnostic performance of magnetic resonance imaging (mri), computed tomography (ct), and clinical figo staging in patients with invasive cervical cancer. * compare the accuracy of mri, ct, and clinical figo staging in the evaluation of morphologic tumor prognostic factors in figo stage ib1 and stage ib2 and greater in these patients. * examine the value of imaging assessment of tumor prognostic factors (alone or in combination) as predictors of recurrence within 2 years of surgery in these patients. * evaluate the quality of life in the 12-month period after staging and treatment to potentially change staging accuracy. outline: this is a multicenter study. patients undergo a computed tomography scan with iodinated contrast dye followed by a magnetic resonance imaging scan with or without contrast comprising gadopentetate dimeglumine or vice versa. within 6 weeks of first protocol imaging study, patients undergo one of the following surgeries: * laparoscopic, transabdominal, or transvaginal hysterectomy * extrafascial total abdominal hysterectomy * trachelectomy quality of life is assessed at 1 and 12 months. patients are followed every 3 months for 1 year and then every 6 months for 1 year. projected accrual: a total of 465 patients will be accrued for this study within 18 months.

Eligibility criteria:
disease characteristics: * histologically confirmed invasive cervical cancer, including invasive squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma * figo stage ib1 with clinically visible gross lesion or * figo stage ib2 or greater * scheduled for one of the following surgeries at a participating gynecological oncology group center: * laparoscopic, transabdominal, or transvaginal hysterectomy * extrafascial total abdominal hysterectomy * trachelectomy * not scheduled for a loop electrosurgical excision procedure or a cone biopsy only patient characteristics: age: * not specified performance status: * not specified life expectancy: * not specified hematopoietic: * not specified hepatic: * not specified renal: * not specified cardiovascular: * no cardiac pacemakers pulmonary: * no asthma other: * not pregnant * no contraindication to computed tomography (ct) (e.g., history of allergy to ct contrast medium) * no contraindication to magnetic resonance imaging (e.g., intracranial vascular clip) * no nonmalignant general medical or psychiatric condition that would preclude consent or surgery prior concurrent therapy: biologic therapy: * not specified chemotherapy: * no prior chemotherapy endocrine therapy: * not specified radiotherapy: * no prior radiotherapy for invasive cervical cancer surgery: * see disease characteristics * no prior surgery for invasive cervical cancer other: * no prior medical treatment for invasive cervical cancer
