RATIONALE: Drugs used in chemotherapy, such as cisplatin and doxorubicin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Thalidomide may stop the growth of liver cancer by blocking blood flow to the tumor. Chemoembolization kills tumor cells by blocking the blood flow to the tumor and keeping chemotherapy drugs near the tumor. Giving combination chemotherapy, thalidomide, and chemoembolization before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. Giving thalidomide together with chemotherapy after surgery may kill any remaining tumor cells and prevent the tumor from coming back.
PURPOSE: This phase II trial is studying how well giving combination chemotherapy and thalidomide together with chemoembolization works in treating younger patients undergoing surgery for newly diagnosed liver cancer.

- Study Type: Interventional
- Study Design
- Allocation: Non-Randomized
- Primary Purpose: Treatment
- Masking: None (Open Label)
- Study Primary Completion Date: April 2009
- Determine the event-free and overall survival of younger patients undergoing surgery for newly diagnosed, noncirrhotic hepatocellular carcinoma (HCC) treated with neoadjuvant cisplatin, doxorubicin hydrochloride, and thalidomide (PLADOTH) followed by transarterial hepatic arterial chemoembolization comprising cisplatin and doxorubicin hydrochloride and adjuvant cyclophosphamide and thalidomide.
- Determine the efficacy and tolerability of PLADOTH in patients with initially unresectable noncirrhotic HCC treated with this regimen.
- Determine the rate of complete surgical resection by encouragement of liver transplantation in the treatment strategy as a valid option for tumor removal when partial liver resection or other surgical options remain unfeasible for patients treated with this regimen.
- Determine the long-term remission and decreased relapse rates of patients treated with this regimen based on the postoperative regimen.
- Determine the response rate of patients treated with this regimen after treatment with PLADOTH.
- Determine the short-term toxicity and feasibility of PLADOTH in patients treated with this regimen.
- Determine the efficacy and toxicity of the postoperative regimen in terms of maintenance and duration of complete remission (no more evidence of disease and normal alpha-fetoprotein, if initially elevated) in patients treated with this regimen.
- Determine whether response to PLADOTH by the RECIST criteria can be used for better monitoring of response of patients treated with this regimen.
- Determine whether the rate of fall of serum VEGF and bFGF levels during PLADOTH can be used as prognostic factors for short-term and long-term outcome in patients treated with this regimen.
- Determine the feasibility of chemoembolization in patients treated with this regimen who do not respond to PLADOTH.
- Determine which subset of tumors may benefit from an angiostatic treatment approach based on radiological, surgical, and pathological data collected from patients treated with this regimen.
- Identify possible novel factors that might influence treatment choice and disease outcome based on radiological, surgical, and pathological data collected from patients treated with this regimen.
- Determine guidelines for diagnostic, therapeutic, and follow-up management that would improve clinical care for patients treated with this regimen.
OUTLINE: This is a multicenter, nonrandomized, open-label study.
All patients undergo either tumor biopsy or resection. Patients with localized resectable tumors undergo resection. They then proceed directly to the postoperative treatment. Patients with initially unresectable tumors undergo biopsy then proceed to the pre-operative regimen.
- Pre-operative chemotherapy and thalidomide (PLADOTH): Patients receive PLADOTH comprising cisplatin IV continuously over 24 hours on day 1, doxorubicin hydrochloride IV over 1 hour on days 1 and 2 (or IV continuously over 24 hours on days 1 and 3), and oral thalidomide daily on days 1-21. Treatment repeats every 21 days for 4 courses in the absence of disease progression or unacceptable toxicity. Patients whose tumors are deemed resectable proceed to surgery. Patients with responding disease but whose tumors remain unresectable proceed to chemoembolization or receive 2 additional courses of PLADOTH.
- Transarterial hepatic artery chemoembolization (TACE): Patients undergo TACE comprising cisplatin and doxorubicin hydrochloride administered through a catheter placed near the tumor. TACE may be repeated every 3-4 weeks for as long as disease continues to respond or until the tumor becomes resectable. Patients also receive oral thalidomide once daily during TACE. Once the tumor is deemed resectable, patients proceed to surgery.
- Surgery: Patients undergo surgical resection of the tumor. Patients undergo either partial or total hepatectomy followed by a liver transplant and lung surgery, if necessary. Patients then proceed to the postoperative treatment.
- Postoperative treatment: Beginning within 6 weeks after surgery, patients receive oral cyclophosphamide once every other day and oral thalidomide once daily for up to 1 year in the absence of disease progression or unacceptable toxicity.
Patients with metastatic disease who show disease progression at any time during treatment go off study and receive individual advice regarding further treatment based on the decision of the principal investigator.
After completion of study treatment, patients are followed periodically for 5 years.
