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.

Condition Intervention
Unspecified Adult Solid Tumor, Protocol Specific Other: fluorine F 18 fluorothymidine Device: positron emission tomography Device: magnetic resonance imaging

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: A Pilot Study of FLT-PET/MRI for Early Response Monitoring to Novel Cancer Therapeutic Agents

Further study details as provided by Case Comprehensive Cancer Center:

Primary Outcome Measures:
  • Concordance analysis of standardized uptake values (SUVs) between the 2 baseline scans [ Time Frame: Baseline ]
    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 Images [ Time Frame: Up to 4 weeks ]
    Describe changes in images at baseline PET/MRI scan compared to PET/MRI image taken after initiation of anti-angiogenic therapy

Estimated Enrollment: 20
Actual Study Start Date: October 22, 2013
Estimated Study Completion Date: December 2018
Estimated Primary Completion Date: December 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Diagnostic (FLT-PET/MRI)
Patients undergo FLT-PET/MRI twice at baseline and once within 4 weeks after start of treatment.

Detailed Description:


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.


  • 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.


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