• No retinal or visual field changes from prior 4-aminoquinoline compound use
• No history of allergic reactions attributed to compounds of similar chemical or biologic composition to capecitabine or hydroxychloroquine
• No other concurrent serious systemic disorders (including active infections) that, in the investigator's opinion, would compromise the safety of the patient or compromise the patient's ability to complete the study

PRIOR CONCURRENT THERAPY:

• See Disease Characteristics
