FLT-PET/MRI for Early Response Monitoring to Novel Cancer Therapeutic Agents

Completed
Conditions
Unspecified Adult Solid Tumor, Protocol Specific
Registration Number
NCT02055586
Lead Sponsor
Case Comprehensive Cancer Center
Brief Summary

This pilot clinical trial studies fluorine F 18 fluorothymidine (FLT)-positron emission tomography/magnetic resonance imaging (PET/MRI) in measuring early response in patients with metastatic solid tumors receiving treatment that blocks blood flow to the tumor. Diagnostic procedures, such as FLT-PET/MRI, may help measure a patient's response earlier during treatment.

Detailed Description

PRIMARY OBJECTIVES:

The primary objective of this pilot imaging study is to determine the feasibility of FLTPET/MR imaging for early prediction of treatment response in patients undergoing antiangiogenic cancer treatment. The study will assess PET/MRI test-retest reproducibility and compare baseline PET/MRI with PET/MRI after initiation (within 2-4 weeks) of antiangiogenic therapy.

SECONDARY OBJECTIVES:

* To compare early changes in PET biomarker (FLT) tumor uptake with treatment response assessed at completion of therapy (prediction of treatment response).

* To compare changes in MRI signal intensities (multi-parametric MRI) with treatment response assessed at completion of therapy.

* To compare results from multi-parametric MR imaging with FLT tumor uptake.

* To assess combinations of quantitative PET and MRI metrics.

OUTLINE:

Patients undergo FLT-PET/MRI twice at baseline and once within 4 weeks after start of treatment.

Primary Outcome Measures
NameTimeMethod
Concordance analysis of standardized uptake values (SUVs) between the 2 baseline scansBaseline

A sample size of 20 produces a two-sided 95% confidence interval \[0.553, 0.918\] for the Pearson correlation coefficient when the sample correlation is 0.80. Additional analysis for concordance will include Bland-Altman plots and intraclass correlation.

Comparative Analysis of PET/MRI ImagesUp to 4 weeks

Describe changes in images at baseline PET/MRI scan compared to PET/MRI image taken after initiation of anti-angiogenic therapy
