Clinical Trial Summary
This project is a pilot study to interrogate the potential of LMS as a predictive tool for
the selection of therapy for HCC patients. The reliability of LMS to predict patients'
response following HCC therapy will leverage on an algorithm that is built from the pool of
MRI scans from HCC patients pre- and post-treatment. In the study, MRI scans of 30 HCC and
metastatic colorectal cancer (CM) patients (ratio of 4:1) will be analysed. CM cancer
patients include patients whose cancers metastasized from colorectal cancer or primary liver
cancer. These patients will either receive one of the treatment, surgical resection, Y90 or
systemic therapy. A total of 4 MRI scans will be taken for each patient; the first MRI scan
will be taken within a month before treatment initiation and the remaining MRI scans will be
taken at the 1st, 3rd and 9th month post-initiation of treatment.
Description:
Liver cancer is currently the second most common cause of cancer-related death worldwide, and
hepatocellular carcinoma (HCC) accounts for more than 90% of liver cancers. There has been a
marked increase in HCC-related annual death rates over the past two decades, with the
majority of all cases of HCC worldwide found in the Asia-Pacific region. As such, HCC
represents a major public health problem in the Asia-Pacific region and globally. There are a
significant number of variables known to influence the prognosis of HCC, with the stage of
underlying liver disease being a dominant factor. Elucidating these variables remains a
challenge and the poor understanding of these variables has translated to poor
prognostication of treatment outcomes. To date, no ideal predictive modality has been
developed. One of the treatment therapies in HCC is surgical resection. Despite advances in
the surgical and perioperative fields, potential posthepatectomy liver failure (PHLF)
persists as a life-threatening complication, and is reported in up to 15% of patients (Aliza
et al., 2017). This accentuates the need to develop accurate methods to quantitatively
characterize future liver remnants (FLR) prior to surgery, as postoperative outcomes mainly
depend on the size and quality of FLR (Cieslak et al., 2014).
This study seeks to address this unmet need as we will employ the LMS platform to assess and
monitor changes in the liver health of HCC patients following treatment. In addition, this
platform will be leveraged upon to monitor patients' response to the different treatment
modalities such as surgical resection, Y90 and systemic therapy. These aims will be achieved
through the quantitative characterization of liver tissues, which forms the basis of LMS
technology. LMS is an MRI-based non-invasive tool that has attained CE marking and FDA
clearance to aid the diagnosis of patients with liver disease. This technology is highly
sensitive to subtle differences in liver tissue composition and samples the entire liver
quickly, rendering it an ideal platform for liver tissue characterisation. LMS uses MRI
mapping techniques to characterize liver tissue at the cellular level, delivering the
quantification of liver fat and correlates of fibroinflammation and iron load using proton
density fat fraction (PDFF), T1 and T2* maps, respectively. The modelling algorithms of this
device correct the T1 map (cT1) for the confounding effect of iron overload. In addition,
this platform has further refined the measurements for PDFF to be more accurate in liver
tissue characterisation. Previously, the use of LMS to predict clinical outcomes through
tissue characterisation has been validated in a few clinical studies on patients with liver
disease. In a prospective general hepatology clinical cohort following 112 patients for a
median of 27 months, patients with higher cT1 values tended to experience clinical events,
whereas patients with normal or low cT1 values had no clinical events (Pavlides et al.,
2016). Additionally, from a prospective study on 71 patients with suspected non-alcoholic
fatty liver disease (NAFLD), cT1 values have been shown to correlated with cirrhosis,
ballooning and significant NAFLD (Pavlides et al., 2016). Finally, an independent study has
also demonstrated the utility of T1 mapping in predicting clinical outcomes and for
distinguishing decompensated cirrhotics from compensated cirrhotics (Bradley, 2018).
In-depth characterisation of liver tissues will be done following Couinaud segmentation of
the liver. Specific to the surgical resection cohort, estimated FLR volume and cT1 will be
combined to refine the LMS platform in the assessment of liver health. The significance of
this in the long term resides in more accurate assessment of surgical risks, which is
paramount to improve the care of HCC patients considered for surgical resection. By adopting
the LMS platform to monitor patients' response to treatment longitudinally through the
characterisation of their liver tissues, our study also seeks to discern features present in
the LMS platform that are predictive of patients' outcomes. Additionally, this study will
compare anonymized blood test results and anonymized histological reports (histological
reports only for the surgical resection cohort) against features observed in the LMS platform
to better discern features indicative of patients' outcomes.
This study will monitor patients closely before treatment and after their treatment with
follow-up visits, and the MRI scans of these patients across these visits will be analysed
using the LMS. A total of 4 MRI scans will be taken for each patient with 1st MRI scan taken
within 6 weeks before treatment and the remaining MRI scans taken at the 1st, 3rd and 9th
month post-initiation of treatment.
