How to predict which patients with initially unresectable liver cancer are more likely to respond to conversion therapy remains an important unresolved problem in guiding treatment strategy and surgical timing. Substantial variation exists among patients in their tumor response to the same conversion therapy regimen, and current pretreatment imaging assessment does not adequately capture this inter-individual variability. We hypothesize that baseline tumor viscoelastic parameters measured by three-dimensional magnetic resonance elastography (3D-MRE) differ substantially across patients, and that this inter-individual heterogeneity may be associated with differential response to conversion therapy. This study aims to prospectively evaluate the association between baseline 3D-MRE-derived tumor viscoelastic parameters and pathological response as well as surgical conversion outcomes across patients with liver cancer receiving conversion therapy.

This study will enroll adult patients with initially unresectable liver cancer, including hepatocellular carcinoma, intrahepatic cholangiocarcinoma, or liver metastases (e.g., from colorectal cancer), who are planned to receive conversion therapy at the Second Affiliated Hospital of Xi'an Jiaotong University, with the treatment goal of achieving surgical resectability. Eligible patients will undergo 3D-MRE examinations prior to conversion therapy. Patients will be consecutively recruited from the hepatobiliary oncology multidisciplinary team (MDT) of the study center prior to initiation of conversion therapy.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.
The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.
The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.
“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Patients with initially unresectable liver cancer who are planned to receive conversion therapy will undergo a baseline three-dimensional magnetic resonance elastography (3D-MRE) examination prior to treatment initiation, in addition to standard-of-care evaluation. 3D-MRE will be used to quantify tumor viscoelastic parameters (including stiffness, storage modulus, loss modulus, and damping ratio) at baseline. These baseline imaging parameters will be compared across patients and analyzed for their association with subsequent pathological response and surgical conversion outcomes following conversion therapy. The examination does not alter the standard treatment regimen selected by the treating physician.
Objective Response Rate (ORR) after conversion therapy
Response evaluated according to RECIST 1.1 or mRECIST criteria based on imaging assessment after conversion therapy, analyzed in relation to baseline 3D-MRE parameters
Time frame: At the time of post-conversion therapy imaging evaluation (approximately 8-12 weeks after treatment initiation)
Association between baseline 3D-MRE parameters and pathological response
Correlation between baseline tumor stiffness (measured in kilopascals by three-dimensional magnetic resonance elastography) and pathological response status (major pathological response \[≤10% residual viable tumor\] vs. non-major pathological response, assessed by histopathological examination of the surgical specimen) in patients who undergo surgical resection following conversion therapy.
Time frame: Baseline (pre-treatment); surgical pathology if resection is performed
Surgical Conversion Rate
Proportion of patients who successfully undergo surgical resection after conversion therapy
Time frame: Up to 6 months after conversion therapy initiation
Predictive accuracy (AUC) of baseline 3D-MRE parameters for treatment response
Area under the receiver operating characteristic curve (AUC) for baseline 3D-MRE-derived tumor stiffness in predicting objective response (per RECIST 1.1 or mRECIST) to conversion therapy.
Time frame: Baseline through 12 weeks
