Stage IA1 Cervical Cancer, Stage IA2 Cervical Cancer, Stage IA Cervical Cancer, Stage IB1 Cervical Cancer, Stage IB2 Cervical Cancer, Stage IB3 Cervical Cancer, Stage IB Cervical Cancer
Conditions
Brief summary
This trial studies how well positron emission tomography/magnetic resonance imaging (PET/MRI) scan works in checking patients with stage IA1-IB3 cervical cancer that can be removed by surgery (resectable). PET/MRI scan may help doctors learn more about the spread of the disease.
Detailed description
PRIMARY OBJECTIVE: I. To assess depth of cervical invasion with positron emission tomography/magnetic resonance imaging (PET/MRI) in patients with cervical cancer in clinical Federation of Gynecology and Obstetrics (FIGO) staging undergoing evaluation for surgical resection and correlate with pathology. SECONDARY OBJECTIVES: I. To correlate lymph node involvement on PET/MRI with pathology. II. To assess the inter-observer variability in the interpretation of PET/MRI. III. To correlate the quantitative imaging parameters of the tumor, such as the volumetric size, blood oxygen level dependent (BOLD), intravoxel incoherent motion (IVIM) analysis, apparent diffusion coefficient (ADC), diffusion tensor imaging (DTI), dynamic contrast-enhanced (DCE), metabolic tumor volume (MTV), total lesion glycolysis (TLG), standardized uptake value (SUV) and the glucose metabolic rate (GMR) with lymphovascular space invasion (LVSI) and tumor grade on surgical pathology. OUTLINE: Patients receive fludeoxyglucose F-18 and gadobutrol intravenously (IV) over 1 minute and undergo PET/MRI over 90-120 minutes.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Accuracy of diagnosing depth of invasion on positron emission tomography/magnetic resonance imaging (PET/MRI) | 3 years | Both PET/MRI and pathology results will be dichotomized into binary outcomes and the accuracy of PET/MRI will assessed. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Assessing the Lymph node involvement by PET/MRI | 3 years | Will determine the relationship with pathology. |
| Inter-observer variability of PET/MR | 3 years | A PET report for clinical use will be generated by a radiologist with appropriate training and credentialing to read PET images. A separate MRI report for clinical use will be generated by a radiologist with appropriate training and credentialing to read MRI. Subsequently, PET/MR images will be evaluated by two radiologists who have appropriate training to read both PET and MRI and 2 research reports will be generated. Inter-observer variability of PET/MRI will be calculated using Cohen's kappa coefficient. |
| Quantitative imaging parameters of the tumor | 3 years | Correlate the quantitative imaging parameters of the tumor, such as the volumetric size, blood oxygen level-dependent (BOLD), apparent diffusion coefficient (ADC), IVIM analysis, diffusion tensor imaging (DTI), dynamic contrast-enhanced (DCE), MTV, TLG, standardized uptake value (SUV) and GMR with LVSI and tumor grade on surgical pathology which serves as gold standard. Two-sample t-test or analysis of variance (ANOVA) will be used for comparing the group means between LVSI positive/negative groups and among tumor grades and types. Other statistical analysis will be carried out as appropriate. |
