OUTLINE: Patients receive low-dose oral cyclophosphamide once daily on days 1-21 and undergo 3-dimensional conformal radiotherapy on days 21-23. On day 24, patients undergo an intra- or peri-tumoral polyinosinic-polycytidylic acid polylysine carboxymethylcellulose (poly ICLC) injection directly into the tumor followed by trans-hepatic artery embolization to the designated tumor. Patients receive poly ICLC subcutaneously on days 26, 35, 37, 42, 44, 49, and 51. Treatment repeats every 57 days for up to 3 courses in the absence of disease progression or unacceptable toxicity.
