Phase II Trial of 64Cu-ATSM PET/CT in Cervical Cancer (ACRIN6682)
RATIONALE: Diagnostic procedures, such as copper Cu 64-ATSM PET/CT scans, may help doctors predict how patients will respond to treatment.
PURPOSE: This phase II trial is studying how well copper Cu 64-ATSM PET/CT scans work in predicting disease progression in patients undergoing standard of care treatment with cisplatin and radiation therapy (external beam and brachytherapy) per NCCN guidelines for newly-diagnosed stage IB, stage II, stage III, or stage IVA cervical cancer.

- To define the role of pre-therapy ^64Cu-labeled diacetyl-bis(N4-methylthiosemicarbazone) (copper Cu 64-ATSM) in predicting prognosis and determining the behavior of an invasive squamous cell cervical cancer in patients with newly-diagnosed stage IB2-IVA cervical squamous cell carcinoma.
- To determine whether higher copper Cu 64-ATSM uptake is associated with lower progression-free survival of these patients after chemoradiotherapy.
- To determine if higher copper Cu 64-ATSM uptake is associated with lower overall survival of these patients.
- To determine if higher copper Cu 64-ATSM uptake is associated with earlier primary cervical tumor recurrence and a higher rate of development of distant metastatic disease in these patients.
- To determine if higher copper Cu 64-ATSM uptake is associated with a lower frequency of complete metabolic response on FDG-PET/CT scan performed 3 months after completion of radiotherapy and chemotherapy.
- To estimate the accuracy of copper Cu 64-ATSM uptake as a predictor of progression-free survival, overall survival, primary tumor recurrence, and future development of distant metastatic disease in these patients.
- To evaluate the performance of copper Cu 64-ATSM uptake as a predictor of lymph node metastasis at study entry.
- To evaluate whether copper Cu 64-ATSM uptake correlates with tumor volume at study entry.
- To examine the relationship between tumor uptake of copper Cu 64-ATSM and other markers of tumor hypoxia, including VEGF, GLUT-1, CA-IX, and OPN.
- To compare the predictive ability of pre-therapy copper Cu 64-ATSM-PET to that of post-therapy FDG-PET/CT scan.
- To assess whether pre-therapy FDG-PET/CT findings are predictive of progression-free survival.
OUTLINE: This is a multicenter study.
Patients receive copper Cu 64-ATSM IV and undergo PET/CT scan over 30 minutes 30-40 minutes later. Within 4 weeks after copper Cu 64-ATSM-PET/CT scan, patients begin planned concurrent standard of care chemoradiotherapy comprising 6 weeks of radiotherapy (external beam and brachytherapy)and weekly cisplatin administration per NCCN guidelines. Patients then undergo FDG-PET/CT scan 3 months after completion of chemoradiotherapy.
Tissue samples from previously collected cervical biopsy (obtained for diagnosis) are used for detecting hypoxic markers by immunohistochemistry analysis.
After completion of study intervention, patients are followed for every 3 months for 2 years and then every 6 months for 1 year.
