Consolidative Radiotherapy for Colorectal Cancer Liver Metastases Receiving Surgery or Radiofrequency Ablation

December 31, 2023 updated by: Tao Zhang, Wuhan Union Hospital, China
This study is a randomized phase II trial to evaluate the efficacy of adjuvant consolidative radiotherapy in colorectal cancer liver metastasis (CRLM) patients after chemotherapy combined with surgical resection or radiofrequency ablation of liver lesions.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Withdrawn

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.

Detailed Description

Liver metastases are detected in 40-50% of patients diagnosed with colorectal cancer. Local treatments like surgical resection or radiofrequency ablation result in 5-year survival of 35%. However, relapse still occurs in 70% of patients. Stereotactic body radiotherapy (SBRT) has emerged as a valid treatment not only to provide excellent symptom palliation, but also is effective in local control of metastatic lesions and improves survival. The potential efficacy of SBRT as adjuvant radiotherapy in CRLM patients after surgical resection or radiofrequency ablation is still unknown.

Study Type

Interventional

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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
Disease free survival
Time Frame: 2 years
Evaluate the effect of consolidative SBRT of liver lesions versus observation on disease free survival
2 years

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.
Outcome Measure
Measure Description
Time Frame
Overall survival
Time Frame: 5 years
To evaluate overall survival after consolidative SBRT in comparison to observation alone
5 years
Intrahepatic disease free survival
Time Frame: 2 years
To evaluate Intrahepatic disease free survival after consolidative SBRT in comparison to observation alone
2 years
Toxicities
Time Frame: 2 years
Acute toxicity was scored according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) v3.0 criteria during and up to 3 months after radiotherapy. Late toxicity was graded using the Radiation Therapy Oncology Group (RTOG)/European Organisation for the Research and Treatment of Cancer (EORTC) criteria.
