Overview
Brief Summary
This study is designed to see whether stereotactic body radiation therapy (SBRT) can reduce tumour size, slow progression of the disease, prolong life and improve quality of life of patients with hepatocellular carcinoma, a cancer of the liver, that cannot be removed surgically (unresectable) and cannot be treated with ablative therapy (e.g. radio-frequency ablation) or trans-arterial chemo-embolization (TACE) therapy (delivery of chemotherapy through an artery that feeds into the liver). SBRT is concentrated focused radiation therapy delivered very precisely to the liver tumour. It is hoped that knowledge obtained from this study will improve our ability to treat patients with liver tumours that cannot be treated with surgery and other methods, and that SBRT may prove to be a treatment that can lead to long-term and permanent control of liver tumours for some patients.
Detailed Description
From July 2003 to May 2007, over 40 patients with hepatocellular carcinoma participated in two studies at Princess Margaret Hospital (PMH) designed to determine the safety of treating hepatocellular carcinoma with SBRT. These studies have shown that SBRT can be delivered safely to the majority of patients with hepatocellular carcinoma. The treated tumour was controlled (shrank or remained the same size) in 78% of patients at one year following treatment.The median survival of patients was 11 months (i.e. half of patients survived longer and half shorter than 11 months). This survival rate is better than that expected in patients treated with supportive care only (no treatment other than care to make you feel better). Supportive care patients have a median survival rate of 3-9 months. We expect that the benefits of SBRT in this study will be similar to those observed in our initial studies.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Confirmed pathologically, 2)diagnosed by showing vascular enhancement of the lesion on at least two imaging techniques, or 3) diagnosed by showing vascular enhancement on a single technique if the AFP is greater than 200, in the setting of cirrhosis or chronic hepatitis B without cirrhosis (EASL consensus conference guidelines).
- •Either 1) the tumour must be unresectable, based on the opinion of an experienced surgeon specializing in hepatic resection, or 2) the patient Phase II SBRT HCC 13 must be medically inoperable, or 3) extra-hepatic metastases must be present (making hepatic surgery an inappropriate treatment option).
- •Karnofsky performance status (KPS) \> 60 (Appendix II)
- •Age: 18 years or older. Both male \& female patients of all races can be included in this study. Female patients within reproductive years may not be, nor become, pregnant during participation in this study
- •Patients must have recovered from the effects of previous therapy.
- •Maximal tumor size of 15 cm.
- •Adequate organ function as assessed as follows:
- •Hemoglobin \> 90 g/L
- •Absolute neutrophil count \> 1.0 bil/L
- •Platelets \> 50 bil/L
Exclusion Criteria
- •Patients with active hepatitis or encephalopathy related to liver failure
- •Prior radiation therapy to the right upper abdomen, precluding reirradiation of the liver. That is, any previous radiation therapy in which a mean dose to the liver of 15 Gy in conventional fractionation was delivered, or previous doses to critical normal structures that would make re-irradiation unsafe. The PI should be called if there is any question of safety of re-irradiation.
- •Eligible for RFA or alcohol ablation
- •Eligible for TACE
- •Prior uncontrolled, life threatening malignancy within the six months.
- •Pregnancy is not permitted, and in women of child bearing age, a pregnancy test and acceptable methods of contraception are warranted.
- •Previous gastric, duodenal or variceal bleed within the past 2 months.
- •Commencement of coumadin use within the past 3 months.
