I am late to this party but let me chime in with my support for curative. Palliative care implies that there is no attempt being made to cure the illness (e.g. metastatic cancer). Examples include morphine to relieve pain, or radiation treatments to shrink a tumor that is partially obstructing the airway. These treatments improve the patient's quality of life, and may even extend life somewhat, but in no way are they expected to completely cure the patient. Curative care, of course, is delivered with the aim of eradicating disease completely.
