About

This is a randomized phase II study comparing microwave ablation (MWA) and stereotactic body radiation therapy (SBRT) for localized hepatocellular carcinoma (HCC).

This trial will be the first prospective comparison of these modalities for the treatment of HCC and will provide critical information regarding which local ablative modality is most appropriate for which patients. This study will also provide important information regarding quality of life and liver function changes following these two different treatment modalities.

Inclusion criteria

Patients with hepatocellular carcinoma (HCC) are eligible for this trial. HCC is defined as having at least one of the following:
1. HCC diagnosed either on biopsy or based on standard imaging criteria on contrast enhanced CT or MRI (arterial enhancement with washout and pseudocapsule); or
2. A discrete hepatic tumor(s) as defined by the Barcelona criteria10 for cirrhotic patients, >1 cm with arterial hypervascularity and venous or delayed phase washout on CT or MRI
3. Presentation at multidisciplinary liver tumor board to assess eligibility for either SBRT or MWA
Patients must have 1-2 intrahepatic foci of HCC and may not be candidates for refuse hepatic resection. Patients who are on the organ wait list for (orthotopic liver transplantation) OLT will be considered for this trial as a "bridge" to transplant.
Patients with 1 focus of HCC will be eligible if their tumor is 3.5 cm or less in greatest diameter. Patients with 2 foci of HCC will be eligible if each lesion is 3.5 cm in diameter or less and the combined diameter of both lesions is 5 cm or less.
The foci of HCC must be in an anatomic location amendable to treatment by both MWA and SBRT.
The patient must have an ECOG performance status of ≤ 2 (Eastern Cooperative Oncology Group Performance Status is an attempt to quantify cancer patients' general well-being and activities of daily life. The score ranges from 0 to 5 where 0 is asymptomatic and 5 is death).
Patients must have recovered from the acute effects of prior liver-directed therapy (e.g., RT, RFA, MWA or TACE) and a minimum of 4 weeks must have passed since the last procedure and protocol therapy.
Patients must have:
1. Platelets ≥ 50,000/mm3
2. Child Pugh class A liver function or class B7 (Appendix II)
3. INR (international normalized ratio (for anticoagulant monitoring)) < 1.5
The patient must have a life expectancy of at least 12 weeks
The patient must be at least 18 years old
Patients must sign an IRB approved informed consent form for this purpose indicating that they are aware of the investigational aspects of the treatment and the potential risks. They also must be able to understand and the willing to sign a written informed consent.

Exclusion criteria

Patients who have received prior abdominal radiation
Patients with 3 or more foci of HCC
Patients whose HCC involves the local vasculature, regional lymph nodes or distant metastatic sites
Patients with Child Pugh liver function worse than B7
