Epidemiologic research of rare cancers: trends, resources, and challenges

Cette étude présente les activités d'une division du "National Cancer Institute" en matière de recherche sur les cancers rares (45 types de cancers) et les enjeux associés

Background: The goals of this project were to assess the status of National Cancer Institute (NCI) rare cancer-focused population science research managed by the Division of Cancer Control and Population Sciences (DCCPS), to develop a framework for evaluation of rare cancer research activities, and to review available resources to study rare cancers.

Methods: Cancer types with an overall age-adjusted incidence rate of less than 20 cases per 100,000 individuals were identified using NCI Surveillance, Epidemiology and End Results (SEER) Program data. SEER data were utilized to develop of a framework based on statistical commonalities. A portfolio analysis of DCCPS-supported active grants and a review of three genomic databases were conducted.

Results: For the 45 rare cancer types included in the analysis, 123 active DCCPS-supported rare cancer-focused grants were identified, of which the highest percentage (18.7%) focused on ovarian cancer. The developed framework revealed five clusters of rare cancer types. The cluster with the highest number of grants (n=43) and grants per cancer type (10.8) was the cluster that included cancer types of higher incidence, average to better survival, and high prevalence (in comparison to other rare cancers). Resource review revealed rare cancers are represented in available genomic resources, but to a lesser extent compared to more common cancers.

Conclusions: This manuscript provides an overview of the rare cancer-focused population sciences research landscape as well as information on gaps and opportunities.

Impact:The findings of this manuscript can be used to develop efficient and comprehensive strategies to accelerate rare cancer research.
