The legislation in North Carolina requires the collection of follow-up data by the Central Cancer Registry. This study compares the passive follow-up method to the active follow-up method that requires many more resources.

This study examines the survival rates among brain cancer patients in North Carolina from the period of 1990 through 1995. Follow-up of these patients is carried through 1997. There were 2778 cases of brain cancer in that period of time. The results are to be compared with SEER data to check for reliability of the data and to determine the effectiveness of passive follow-up.
