Experimental
WBRT Followed by Standard of Care
WBRT+Capecitabine Followed by Capecitabine Maintenance
Participants will receive 3000 centi-Gray (cGy) WBRT in 10 single daily fractions over 12 to 14 days (300 cGy / fraction) followed by standard of care therapy at the discretion of the treating oncologist starting no earlier than 2 weeks after completion of WBRT. The participants will be followed during the treatment until the halting of standard of care for any reason (central nervous system [CNS] or extra-cranial tumor progression, unacceptable toxicity, change of therapeutic strategy, withdrawal of participant consent, or death).
Participants will receive 3000 cGy WBRT in 10 single daily fractions over 12 to 14 days (300 cGy / fraction) concurrent with capecitabine 825 milligrams per square meter (mg/m^2) orally twice daily, Days 1-14 of a 21 day cycle for 1 cycle followed by capecitabine 1000 mg/m^2 orally twice daily Days 1-14 every 21 days starting with Cycle 2, one week after completion of WBRT and continuing until the halting of capecitabine for any reason (CNS or extra-cranial progression, unacceptable toxicity, withdrawal of participant consent or death).
