Experimental: Radiation Therapy (RT) and Chemotherapy
Upon enrollment in the study, patients will undergo radiation simulation. Protocol therapy will start upon completion of RT planning (1-2 weeks). Chemoradiation will be initiated 1-2 weeks later depending on RT planning and consist of whole liver irradiation (WLI).
Radiation: Whole liver irradiation (WLI)
Whole liver irradiation (WLI) to a total dose 1800cGy in 10 fractions will be given over 2 weeks with simultaneously integrated boost (SIB) to deliver focal doses of 3600cGy (dose level 1) and 4800cGy (dose level 2) to select gross lesions. SIBl dose assignment will be according to the dose escalation scheme, with all patients in dose level 1 receiving boost of 3600cGy to select lesions and those in dose level 2 receiving boosts of 4800cGy to select lesions. At least one lesion will be selected for dose escalation.
Drug: Gemcitabine and Cisplatin
Patients will start cisplatin 10 mg/m2 and gemcitabine 600 mg/m2 intravenously q2 weeks for 1 cycle while undergoing simulation and radiation treatment planning procedures. After completion of CRT, adjuvant cisplatin 25 mg/m2 and gemcitabine 600 mg/m2 q2 weeks will be continued until progression or unacceptable toxicity.
