Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE3
• Total Enrollment: 136 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2000-01-31
• Study Completion Date: 2012-10-31

Brief Summary

To prospectively evaluate whether use of combined radiofrequency ablation (RFA) and percutaneous iodine-125 (125I) seeds implantation results in better survival compared with use of RFA alone in patients with hepatocellular carcinoma.

Detailed Description

This study was local ethical committee approved; all patients gave written informed consent. A total of 136 patients were randomly assigned to undergo RFA-125I (n = 68; 42 men, 26 women; mean age, 50.7 years; age range, 29-73 years) or RFA alone (n = 68; 47 men, 21 women; mean age, 48.9 years; age range, 30-74 years). Patients with viable tumors at computed tomography (CT) 4 weeks after treatment received additional treatment. Rates of local tumor progression and overall survival were evaluated by using Kaplan-Meier and log-rank tests, respectively. The relative prognostic significance of variables in predicting overall survival and the time to tumor recurrence or metastasis were assessed with multivariate Cox proportional hazards regression and logistic regression analyses, respectively.

Study Groups

RFA-125I group

The combination RFA and 125I (RFA-125I) (n = 68; 42 men, 26 women; mean age, 50.7 years; age range, 29-73 years) In this group, patients were accepted not only radiofrequency ablation (RFA) but also iodine-125.

Group Type: EXPERIMENTAL

Radiofrequency Ablation

Intervention Type: PROCEDURE

For RFA, we used a commercially available system (RF 2000; Radio Therapeutics, Mountain View, Calif) and a needle electrode with a 15-gauge insulated cannula that had 10 hook-shaped expandable electrode tines with a diameter of 3.5 cm at expansion (LeVeen; Radio Therapeutics).The radioactivity per seed ranged from 0.5 to 0.6 millicuries (mCi)

iodine

Intervention Type: RADIATION

The 125I seeds (0.8 mm in diameter and 4.5mm in length) were enclosed in a NiTinol capsule (China Institute of Atomic Energy, Beijing). These seeds could produce 27.4-31.5 keV X-ray and 35.5 Kev γ ray, with a half-life of 59.6 days. The radioactivity per seed ranged from 0.5 to 0.6 millicuries (mCi).

RFA-only group

(n = 68; 47 men, 21 women; mean age, 48.9 years; age range, 30-74 years) In tis group,the patient were just peformed radiofrequency ablation alnoe.

Group Type: ACTIVE_COMPARATOR

Radiofrequency Ablation
