Objectives

Primary

  1. Compare the 30-month overall survival rate of patients with unresectable liver metastases secondary to colorectal adenocarcinoma treated with chemotherapy and bevacizumab with or without radiofrequency interstitial ablation.

Secondary

  1. Compare overall survival of patients treated with these regimens.
  2. Compare quality of life of patients treated with these regimens.
  3. Determine the health economics associated with this study.

Entry Criteria

Disease Characteristics:

  • Unresectable liver metastases secondary to colorectal adenocarcinoma, including:
    • Metastases that cannot be radically resected due to size, location, or number of deposits
    • Metastases invading right and left branches of hepatic artery or portal vein
    • Metastases extended to the 3 main hepatic veins

  • No detectable extra-hepatic disease

  • Fewer than 10 metastatic deposits on liver

  • Total metastatic involvement of liver no more than 50%

  • Adequate treatment of all metastatic lesions deemed possible either by radiofrequency interstitial ablation (RFA) alone or by a combination of resection of resectable lesions and RFA of the remaining unresectable lesions
    • Maximum diameter of 4 cm for lesions to be treated with RFA
    • No maximum diameter of lesions to be resected as long as negative resection margins are obtainable

  • If synchronous liver metastases, must have undergone prior resection of primary tumor

Prior/Concurrent Therapy:

Biologic therapy

  • Not specified

Chemotherapy

  • Prior adjuvant chemotherapy for primary cancer allowed except for patients who received oxaliplatin and have been diagnosed with metastatic disease within 12 months after completion of adjuvant treatment

Endocrine therapy

  • Not specified

Radiotherapy

  • Not specified

  • No bleeding disorder or coagulopathy or need for full-dose anticoagulation

Hepatic

  • Bilirubin less than 3 times upper limit of normal (ULN)
  • Alkaline phosphatase less than 3 times ULN

Renal

  • Creatinine less than 2 times ULN
  • Protein < 0.5 g/24 hr urine collection if proteinuria positive by dipstick

Cardiovascular

  • No uncontrolled congestive heart failure
  • No uncontrolled angina pectoris
  • No uncontrolled hypertension
  • No uncontrolled arrhythmia
  • No myocardial infarction within the past 12 months
  • No cerebrovascular accident or transient ischemic attack within the past 6 months

Other

  • Not pregnant or nursing
  • Fertile patients must use effective contraception
  • No greater than grade 1 peripheral neuropathy
  • No significant neurologic or psychiatric disorder
  • No active infection
  • No contraindication to the use of fluorouracil, leucovorin calcium, oxaliplatin, or bevacizumab
  • No other malignancy within the past 10 years except nonmelanoma skin cancer or carcinoma in situ of the cervix

Expected Enrollment

152

A total of 152 patients (71 per treatment arm) will be accrued for this study within 3 years.

Outcomes

Primary Outcome(s)

Survival rate as measured by Kaplan Meier method at 30 months

Secondary Outcome(s)

Overall survival as measured by Logrank every 3 months for 30 months then every 6 months thereafter
Progression-free survival as measured by Logrank every 3 months for 30 months then every 6 months thereafter
Toxicity as measured by CTC version 2.0 every 3 months for 30 months then every 6 months thereafter
Quality of life as measured by Quality of Life Questionnaire Core 30 (QLQ-C30) version 3.0 at baseline, weeks 6, 12, 18, and 24, every 3 months for years 1-2 after start of treatment, then every 6 months thereafter
Response to treatment (arm II) as measured by RECIST criteria from start of treatment until disease progression

Outline

This is a randomized, open-label, multicenter study. Patients are stratified according to treatment center, prior adjuvant chemotherapy for primary cancer (yes vs no), prior chemotherapy for liver metastases (yes vs no), and route of randomization (before surgery vs during surgery). Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Within 4 weeks of randomization, patients undergo radiofrequency interstitial ablation (RFA) with or without additional resection of resectable lesions. Within 8 weeks after RFA, patients receive chemotherapy and bevacizumab.

  • Arm II: Within 4 weeks of randomization, patients receive chemotherapy and bevacizumab.

In both arms, treatment continues in the absence of disease progression or unacceptable toxicity.

Patients in both arms receive one of the following chemotherapy and bevacizumab regimens to be determined by participating center:

  • Regimen A: Patients receive oxaliplatin IV over 2 hours on day 1 of weeks 1, 3, and 5 and leucovorin calcium IV over 2 hours followed by fluorouracil IV continuously over 24 hours on day 1 of weeks 1-6 and bevacizumab IV over 30-90 minutes on days 1 or 2, 15 or 16, and 29 or 30. Treatment repeats every 7 weeks for 4 courses.

  • Regimen B: Patients receive oxaliplatin IV and leucovorin calcium IV over 2 hours on day 1 followed by fluorouracil IV continuously over 46 hours and bevacizumab IV over 30-90 minutes on day 1 or 3. Treatment repeats every 15 days for 12 courses.

  • Regimen C: Patients receive oxaliplatin IV over 2 hours on day 1 and leucovorin calcium IV over 2 hours followed by fluorouracil IV continuously over 22 hours on days 1 and 2 and bevacizumab IV over 30-90 minutes on day 1 or 3. Treatment repeats every 15 days for 12 courses.

Quality of life is assessed at baseline, within 1 week after completion of RFA (arm I only), within 1 week before start of chemotherapy (arm I only), at weeks 6, 12, 18, and 24 during chemotherapy, every 3 months for 2 years after treatment, and then every 6 months thereafter.

After completion of study treatment, patients are followed every 3 months for 2½ years and then every 6 months thereafter.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol.
