Treatment Selection by 3D Bioprinting Liver Model to Prevent Liver Cancer Recurrence

September 23, 2026 updated by: Albert Chi Yan Chan, The University of Hong Kong

Implementation of Biomimetic 3D Bioprinting Technology in Selecting Optimal Regimens as Adjuvant Therapy to Prevent Hepatocellular Carcinoma Recurrence After Liver Resection or Ablation: a Feasibility Study

This study is a feasibility study about a test on adjuvant therapy for patients in hepatocellular carcinoma (HCC) with a higher risk of tumour recurrence after liver resection or ablation. By collecting individual patient's liver and tumour tissue during surgical operation, 3D bioprinting technology will be adopted to construct patient-specific biomimetic liver models -'Liver-in-Cube', to test and identify the most effective adjuvant therapy for individual patients, thereby personalising treatment and improving treatment outcomes, and hence reducing the recurrence rate of HCC.

This is a phase II, non-randomised, open-label, single-centre, prospective feasibility study designed to evaluate the use of biomimetic 3D bioprinting technology in guiding the selection of adjuvant treatment regimens to prevent hepatocellular carcinoma (HCC) recurrence after curative liver resection. The study will be conducted at Queen Mary Hospital as a 5 years project.

A total of 20 HCC patients who are going to receive liver resection or ablation with a higher risk of tumour recurrence will be recruited. Patients will be identified from clinic and asked if willing to participate in the study. Consent will be signed before operation. Biological samples such as tissue and blood samples will be collected during operation for Liver-in-Cube construction. Patients will receive standard post operative care upon discharge, follow-up in clinic regularly as usual, and be referred to collaborated oncologists for adjuvant therapy. A 1-month post operative scan will also be arranged as standard procedure to confirm the post operative disease status. Result from Liver-in-Cube will be treated as an additional information about adjuvant therapy in preventing HCC recurrence. Patients will discuss with oncologists and decide if to adopt adjuvant therapy or not for HCC recurrence prevention. During the follow-up period, blood samples will also be collected for laboratory analysis outside the routine blood assessment.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

HCC patients who are going to receive liver resection or ablation with a higher risk of tumour recurrence

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of patients have expected result
Time Frame: within 3 years after surgery

Efficacy of Liver-in-Cube in guiding the selection of optimal adjuvant treatment. Eg. Liver-in-Cube suggests drug A for patient A, and patient A receives drug A for treatment, then see if drug A delivers a better response for patient A Time Frame: within 3 years after surgery
within 3 years after surgery
Number of patient who has tumour recurrence
Time Frame: within 3 years after surgery

Recurrence rate
within 3 years after surgery

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
