Relationship Between Copper Cu 64-ATSM Uptake in the Primary Tumor and Progression-free Survival 3 Years After Chemoradiotherapy Primary · every 3 months for first 2 years and every 6 months during year 3, up to 3 years

Progression-free survival (PFS) evaluated every 3 months for first 2 years and every 6 months during year 3 to determine PFS at 3years. Cu64-ATSM Uptake measured within 14 days of baseline Uptake is a measure of activity within a tumor 1. the maximum standardized uptake value (SUVmax = tracer uptake in ROI / (injected activity / patient weight)) 2. Tumor-to-Muscle uptake ratio (T/M, An FDG-PET/CT-guided circular region of interest of 1.0-1.5 cm in diameter is drawn around the most intense region of the primary tumor to calculate the maximum uptake within the region. In addition, regions of i

Relationship Between Copper Cu 64-ATSM Uptake and Complete Metabolic Response Secondary · 3 months after completion of chemoradiation

Complete metabolic response determined by FDG PET/CT performed 3 months after completion of chemoradiation By definition, metabolic response (as defined by NCI Concept ID: C3897320. https://www.ncbi.nlm.nih.gov/medgen/856914) is "the disappearance of metabolic tumor activity in target and non-target lesions, marked by a decrease in tumor standardized uptake value to the level of surrounding normal tissue (tumor uptake/normal uptake = \~1)"

Sponsor's own description

RATIONALE: Diagnostic procedures, such as 64Cu-labeled diacetyl-bis\[N4-methylthiosemicarbazone\] (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 National Comprehensive Cancer Network (NCCN) guidelines for newly-diagnosed stage IB, stage II, stage III, or stage IVA cervical cancer via the Federation of Gynecology and Obstetrics (FIGO) staging systems.
