Louisiana Tumor Registry: new developments and activities.

New developments in the Louisiana Tumor Registry (LTR) over the past 3 years have enhanced the operation of the LTR and broadened its functions. Recent funding for numerous special studies and research collaborations have expanded the registry activities from data collection and special etiologic studies to more completely address the mandates of registry law, which require the LTR to participate in studies of cancer causes, treatment, and survival in order to reduce cancer morbidity and mortality in Louisiana.
