Arm group label:
Hyperpolarized 13C-Pyruvate Magnetic Resonance Spectroscopic Imaging
Summary:
To learn if Hyperpolarized C-Pyruvate Magnetic Resonance (HP-MR) Spectroscopic Imaging
can help doctors detect low-risk (benign) and high-risk (malignant) cysts.
Detailed description:
Primary Objectives:
To explore the use of HP-MR in patients with cystic lesions of the pancreas undergoing
surgical resection. Patients will undergo HP-MR prior to surgical resection (or cyst wall
biopsy) and kpl values will be determined to evaluate metabolic activity. Pathology will
then determine whether the cyst was of benign/low risk or malignant/high risk nature. The
ability for increased kpl to detect an invasive carcinoma will be explored by estimating
the association between lesions' kpl values and lesions' pathological results.
Secondary Objectives:
- A kpl inflection point, or threshold, will then be explored to estimate the
association with malignant/high risk cyst. This threshold value would then undergo
further validation in future studies to calculate the sensitivity and specificity of
this value.
- Correlate HP-MR findings to tissue metabolomics (ex vivo): In all patients who
undergo surgical resection, a small surgical sample will be supplied for ex vivo
metabolomics. NMR metabolomics will be used to measure lactate, creatine, choline,
phosphocholine, glycerophosphocholine, and alanine within the tissue sample. The
highest lactate levels should be found in the most aggressive tumors, which also
should correlate to high kpl.
- Correlate HP-MR findings to blood and cyst fluid biomarkers: Blood samples taken
prior to surgical resection will be analyzed for CA19-9 and CEA. If the patient has
a cystic fluid aspiration prior to surgical resection, then CA19-9, amylase and CEA
will also be measured in these samples. These biomarkers will be compared to
findings from HP-MR and pathologic results.
- Correlate HP-MR findings to immunohistochemical staining for LDH-A and HIF-1α:
Tissue taken from pathology samples for metabolomics will also undergo
immunohistochemical staining for LDH-A and HIF-1α.
- Correlate gut and tissue microbiome with HP-MR findings: Microbiome studies may be
performed under the auspice of another protocol but could be analyzed under this
protocol in relation to HP-MR findings. PA 16-0911 allows for the collection of
stool in patients with cysts of the pancreas for gut microbiome investigation in
relation to the development of pancreatic cancer.
- To explore the safety and tolerability of HP-MR in patients with cystic lesions of
the pancreas undergoing surgical resection or cyst wall biopsy.
