Preoperative Estimation of Microvascular Invasion in Hepatocellular Carcinoma

April 6, 2017 updated by: Ming Kuang

Nomogram for Preoperative Estimation of Microvascular Invasion Risk in Hepatocellular Carcinoma

Presence of microvascular invasion can be estimated preoperatively, by some clinical imaging features such as patient characteristics, serum biomarkers and radiological features. Contrast-enhanced ultrasonography (CEUS) and contrast-enhanced computed tomography (CECT) are routine preoperative conventional examinations for hepatocellular carcinoma (HCC) patients in China. Combining features of CEUS, CECT and clinical factors may improve preoperative MVI assessment. The purpose of this study is to construct a nomogram for preoperative MVI risk estimation with these possible factors.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

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 to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

Study Population

Between April 2017 and April 2019，all consecutive patients who will undergo curative resection (R0 resection) at the First Affiliated Hospital of Sun Yat-Sen University in Guangzhou, China, for HCC based on the modified WHO classification of tumors of the digestive system, are considered for inclusion. By the eligibility criteria stated below, MVI presentative rate is 30-42% in chinese HCC population as reported, and an estimated 400 patients will be needed for this study.

Description

Inclusion Criteria:

  • Asian patients aged 18～80 years old;
  • With no preoperative anti-cancer treatment;
  • Scheduled for radical liver resection;
  • With both CEUS and CECT performed in 4 weeks before surgery;
  • Postoperative histologically confirmed HCC;
  • With sufficient surgical specimen for MVI detection (surgical margin ≥1cm);

Exclusion Criteria:

  • Recurrent HCC or combined hepatocellular-cholangiocarcinoma;
  • With extra-hepatic metastasis or macrovascular invasion;
  • With incomplete clinical and imaging data;
  • Non-radical resection;

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
Preoperative clinical/imaging features
In this project, there is only one study group which comprises of patients with Hepatocellular Carcinoma (HCC) who will undergo contrast-enhanced computed tomography (CECT) and contrast-enhanced ultrasound (CEUS).
Diagnostic test: contrast-enhanced ultrasound
The Aplio SSA-770A or Aplio 500 (Toshiba Medical Systems, Tokyo, Japan) equipped with a 375BT convex transducer (frequency range, 1.9 to 6.0 MHz). CHI is used with a mechanical index that ranged from 0.06 to 0.10. After activating CHI mode, a bolus injection of 2.4 ml of SonoVue (Bracco, Milan, Italy) is administered intravenously via an antecubital vein, followed immediately by a flush of 5 ml of normal saline solution. The targeted lesion should be observed continuously for 5 minutes, and the entire arterial and portal venous phases and several repetitions of the late phase are stored on the hard disk. The arterial, portal venous and late phases are defined as 0-30 s, 31-120 s and 121-360 s after the injection, respectively.
Diagnostic test: contrast-enhanced computed tomography
The Aquilion 64-slice helical CT machine (Tokyo, Japan) is used. The imaging protocol for CT examinations is as follows: 0.5 mm × 64 mm collimation, 120 kV, 150-200 mAs for 64-slice helical CT examination. The standard triphasic scan procedure is used. An unenhanced helical sequence scan through the liver will be performed first; thereafter nonionic iodinated contrast material (Ultravist, Schering, Berlin, Germany) (1.5 mL/kg) will be administered via antecubital vein with power injection at a rate of 4 mL/s for 64-slice helical CT. The arterial phase sequence is obtained 25-32 s after contrast material administration, followed by a portal venous phase sequence 70 s after contrast agent administration.
