Eligible patients (not candidates for curative treatment) will have measurable lesions in the anatomic thorax, abdomen or pelvis (any histology) amenable to palliative radiation treatment (30 Gy in 10 fractions). Patients receive sorafenib orally for one week prior to radiation, then concomitantly for two weeks with radiation and then for one week following completion of radiation. Each anatomic cohort will dose escalate independently. If full oral dose (400 mg po bid) is reached in a given cohort (dose level three) then an additional dose level will open where sorafenib treatment (400 mg bid) is extended following radiation for a total of eight weeks.

Sorafenib orally for one week prior to radiation, then concomitantly for two weeks with radiation and then for one week following completion of radiation. Each anatomic cohort will dose escalate independently. Dose level 1 is 200mg of sorafenib. If full oral dose (400mg orally, twice a day) is reached in a given cohort then an additional dose level will open where sorafenib treatment is extended following radiation for a total of eight weeks.

To measure safety and maximum tolerated dose, all adverse events will be assessed in line with dose limiting toxicities.

To assess the efficacy of adding sorafenib to radiation treatment, radiological imaging will be used to assess response rate inline with the RECIST criteria.
