Radioactive Iodine in Treating Patients Who Have Undergone Surgery for Liver Cancer

A Phase 3 interventional study of adjuvant therapy and iodine I 131 ethiodized oil in Liver Cancer, sponsored by National Medical Research Council (NMRC), Singapore. Status unknown at 3 sites in Singapore. Open to participants aged 17 Years and older. Per ClinicalTrials.gov, last updated 2013-09-20.

Why
  1. The study's title name Carcinoma, Hepatocellular, a narrower term within Liver Neoplasms.
Confidence
High: the new condition is named in the study's own title. Of 46 hand-checked studies reclassified this way, 72% were exactly right and 89% in the right disease family; the registry's first term was right for 4% (measured 2026-10-21). How we classify →

Study summary

RATIONALE: Radioactive iodine may be effective in reducing the rate of recurrence of liver cancer after surgery to remove the tumor. It is not yet known if radioactive iodine is more effective than no further treatment after surgery.

PURPOSE: Randomized phase III trial to determine the effectiveness of radioactive iodine in treating patients who have undergone surgery for liver cancer.

Read the detailed description

OBJECTIVES:

  • Compare the effect of adjuvant hepatic intra-arterial iodine I 131 lipiodol vs observation in terms of rate of recurrence and overall survival of patients with curatively resected hepatocellular carcinoma.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to participating center. Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Within 4-6 weeks after prior resection, patients receive adjuvant hepatic intra-arterial iodine I 131 lipiodol once.
  • Arm II: After prior resection, patients undergo observation. Patients are followed monthly for 1 year and then every 3 months thereafter.

PROJECTED ACCRUAL: A minimum of 300 patients (150 per treatment arm) will be accrued for this study.

Terms in these criteria, in plain language(8)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Karnofsky performance status (KPS)

A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.

Studies often ask for 60 or 70 and above. Your doctor gives the score.

Life expectancy

The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Bilirubin

A yellow substance made when red blood cells are broken down, which the liver clears. A high level can mean a problem with the liver or the bile ducts.

Criteria often allow more for people with Gilbert’s syndrome, a harmless inherited condition that raises bilirubin.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
