23. Any condition that is unstable or could jeopardize the safety or compliance of the patient in the study
24. Previous or concurrent cancer that is distinct in primary site or histology from the cancer being evaluated in the study EXCEPT cervical cancer in situ, treated basal cell carcinoma, superficial bladder tumors (Ta, Tis, and T1) or any cancer curatively treated > 3 years prior to study entry
