Eligibility

Who can join

The film gives the main points. The full list below is copied from the registry; the study team makes the final decision.

  • Age18 Years to no maximum
  • SexAll
  • Healthy volunteersNo

You may be able to join if

  • Age ≥18 years
  • ECOG 0-1
  • Histologically confirmed intrahepatic cholangiocarcinoma (also variously reported as peripheral cholangiocarcinoma, cholangiolar carcinoma or cholangiocellular carcinoma) (IHC). Confirmation of the diagnosis at MSKCC or at the enrolling institution must be obtained prior to randomization.
  • Clinical or radiographic evidence of metastatic disease confined to the liver. Note: presence of regional (porta hepatis) lymph node metastases will be allowed, provided they are amenable to resection. (Note: If peritoneal or other extrahepatic disease is found at time of pump placement, the pump will not be implanted. The patient will be removed from study, deemed nonevaluable and will not count toward the overall study accrual.)
  • Radiographically measurable disease. Measurable disease is defined as disease that can be assessed with 2-dimensional measurements on a cross-sectional imaging. Minimum lesion size is 2 cm in greatest diameter as per RECIST criteria.
  • Disease must be considered unresectable at the time of preoperative evaluation.*
  • Considered candidate for general anesthesia, abdominal exploration and hepatic artery pump placement.
  • Patients with chronic hepatitis and/or cirrhosis are eligible, but must be Child-Pugh class A.
  • WBC ≥ 2,000/mcL , ANC ≥ 1000/mcL
  • Platelet count ≥ 75,000/mcL
  • Creatinine ≤ 1.8 mg/dL
  • Total bilirubin < 1.5 mg/dL
  • Hgb > 7 g/dL The % involvement of the liver will be determined by radiologists after review of imaging

You cannot join if

  • Presence of distant metastatic disease. Patients will undergo radiographic evaluation to exclude the possibility of distant metastatic disease. For patients who have undergone pre- or post-operative biopsies that definitively diagnose IHC, the diagnostic studies may be modified at the discretion of the MSKCC Principal Investigator. Clinical or radiographic evidence of metastatic disease to regional lymph nodes will be allowed, provided it is amenable to resection.
  • Patients previously treated with systemic chemotherapy for IHC will be non-eligible.
  • Prior treatment with FUDR.
  • Prior external beam radiation therapy to the liver.
  • Prior ablative therapy to the liver.
  • Diagnosis of sclerosing cholangitis.
  • Clinical evidence or portal hypertension (ascites, gastroesophageal varices, or portal vein thrombosis; surgically related ascites does not exclude the patient).
  • Active infection within one week prior to HAI placement.
  • Pregnant or lactating women.
  • History of other malignancy within the past 3 years except with early stage/localized cancer that was surgically resected or radiation treatment that would yield the same result as surgery within the past 3 years.
  • Life expectancy <12 weeks.
  • Inability to comply with study and/or follow-up procedures.
  • History of peripheral neuropathy. There is no exclusion of patients based on sex, ethnicity or race. For these reasons, the study results are expected to be generalizable to the Medicare beneficiary population.

The treatment

How it is intended to work

This is how the treatment is meant to work. Whether it helps, and how safe it is, is what this trial is testing.

floxuridine. A fluorinated pyrimidine monophosphate analogue of 5-fluoro-2'-deoxyuridine-5'-phosphate (FUDR-MP) with antineoplastic activity. As an antimetabolite, floxuridine inhibits thymidylate synthetase, resulting in disruption of DNA synthesis and cytotoxicity. This agent is also metabolized to fluorouracil and other metabolites that can be incorporated into RNA and inhibit the utilization of preformed uracil in RNA synthesis. NCI Drug Dictionary

Treatments listed in the registry

  • Gemcitabine (Drug): See arm for details.
  • Oxaliplatin (Drug): See arm for details.
  • Dexamethasone (Drug): See arm for details.
  • Floxuridine (FUDR) (Drug): See arm for details.
  • Implanted Medical Device (Device): Implanted hepatic arterial infusion pump by surgical oncology, to deliver HAI therapy

The study

Treatment groups

Randomized · Crossover · masking: None

HAI FUDR plus GemOx (Arm 1) (Experimental)

Surgical HAI pump placement. 2. HAI FUDR [(0.12 mg/kg/day) x wt (kg) x (30ml) / pump flow rate ] and dexamethasone [1 mg/day * 30] / pump flow rate ] on Day 1 of each cycle. Chemotherapy with HAI FUDR/Dex will commence no sooner than 14 days postsurgical placement of HAI pump. 3. Gemcitabine (800 mg/m2 IV over 30 minutes) and oxaliplatin (85 mg/ m2 IV over 120 minutes on Days 1 and 15 of each cycle; however, for patients in Arm 1, initiation of systemic chemotherapy will not take place until 4 weeks post-surgery for pump placement, so the first dose of systemic chemotherapy will be given on Cycle 1, Day 15, and then every 2 weeks thereafter.

GemOx alone (Arm 2) (Active Comparator)

Gemcitabine (800 mg/m2 IV over 30 minutes) and oxaliplatin (85 mg/m2 IV over approximately 120 minutes) on Days 1 and 15 of each 28-day cycle.For patients in Arm 2, systemic therapy will be administered on Days 1 and Day 15 of each Cycle on a 28-day cycle basis, compromised of Gemcitabine and Oxaliplatin. If a patient randomized to Arm 2 has intrahepatic progression on any follow-up scan during study treatment, that patient will be eligible to crossover to Arm 1 and commence to pump placement surgery and HAI FUDR treatment. Patients with any extrahepatic progression will not be eligible to utilize the crossover arm. Arm 2 patients will have 28 days from date of the scan showing intrahepatic progression to proceed to the crossover arm.
