 | Passive follow-up does a good job of mirroring the results of the active follow-up method in the case of brain cancer. Since brain cancer is often quickly fatal, the chances should be better that the passive method would be successful in this case than in less fatal cancers. |

| While consistent with SEER rates, the question of the difference of survival rates between African-American males and the other race/gender groups is puzzling. |
|
| The differences shown in the observed survival rates in the graphs are not necessarily completely caused by any single factor. The behaviors exhibited may be due to overlapping multiple causes outside this study. |
| This study provides an excellent opportunity for further research on brain cancer survival, such as isolating those factors that cause any differences in survival rates. |
