NCT06588569

Brief Summary

This single-center, parallel-controlled clinical trial aims to establish a multi-mode ablation system for liver malignant tumors originating from the digestive system. The study will evaluate the safety and efficacy of multi-mode tumor ablation, utilizing a multi-mode imaging platform for ablation planning and immediate evaluation of intraoperative ablation effects. Additionally, the study will employ multi-omics and multi-mode imaging techniques to explore the spatiotemporal heterogeneity and immune escape mechanisms of liver metastases from gastrointestinal tumors, providing guidance for treatment strategy formulation and prognostic evaluation.

Outcome Measures

Primary Outcomes (2)

  • Antitumor immune response

    Antitumor immune response is a measure that evaluates the efficacy of multi-mode ablation in activating a durable and specific immune response against tumor cells. This outcome will be assessed as follows: Flow cytometry to quantify the proportions and absolute numbers of immune cell subsets, including CD4+ T cells, CD8+ T cells, NK cells, B cells and dendritic cells (DCs), as well as the immune suppressive myeloid-derived suppressor cells (MDSCs). Cytokine profiling is performed to measure the levels of immune-related cytokines such as interferon-gamma (IFN-γ), interleukin-2 (IL-2), and tumor necrosis factor-alpha (TNF-α). Assessment of immune memory phenotypes through the analysis of T cell receptor (TCR) repertoire diversity and clonality.

    max 24 months

  • 6-month Disease Control Rate

    6-month Disease Control Rate (6-month DCR) refers to the proportion of patients who have a complete response (CR), partial response (PR), or stable disease (SD) at the 6-month follow-up visit.

    6 months

Secondary Outcomes (3)

  • 6-Month Progression-Free Survival

    6 months

  • 1-Year Progression-Free Survival

    1 year

  • 1-Year Overall Survival

    1 year

Study Arms (2)

Multi-mode Ablation

EXPERIMENTAL

This arm includes patients with primary liver cancer or colorectal cancer liver metastasis (five cases each, totaling ten cases) who will receive multi-mode ablation, a novel ablation therapy that combines cryoablation and radiofrequency ablation.

Device: Multi-mode tumor treatment system

Conventional Radiofrequency Ablation

ACTIVE COMPARATOR

This arm includes patients with primary liver cancer or colorectal cancer liver metastasis (five cases each, totaling ten cases) who will receive conventional radiofrequency ablation treatment.

Device: Radiofrequency ablation therapeutic apparatus

Interventions

The intervention for this arm involves the use of a novel multi-mode tumor treatment system, developed by Shanghai MAaGI Medical Technology Co., Ltd. The system combines cryoablation and radiofrequency ablation in a single device. During the treatment, the tumor tissue is rapidly frozen to create an ice ball larger than the lesion by 5mm, followed by thawing and rewarming. Subsequently, the lesion is treated with radiofrequency ablation according to conventional procedures to ensure complete ablation within a safety margin of 5-10mm around the tumor.

Also known as: MTT-P1
Multi-mode Ablation

The intervention for this arm involves the use of conventional radiofrequency ablation equipment, which is developed by MedSphere International (Shanghai) Co., Ltd.. During the treatment, the tumor is ablated using predefined power and time settings to ensure complete ablation within a safety margin of 5-10mm around the tumor.

Also known as: S-1500
Conventional Radiofrequency Ablation
