Assessment of Tobacco Use in Cancer Survivorship Research Among National Cancer Institute-designated Cancer Centers or Affiliated Universities: A Systematic Review

Abstract

This systematic review of the literature examined the role of tobacco use measurement in studies of cancer survivorship performed in the last ten years by National Cancer Institute-designated Cancer Centers or affiliated universities. It was intended to establish the degree to which tobacco use was considered a determining factor. The scientific articles examined for the basis of this review were acquired through PubMed, Google Scholar, references to published papers, and evidence-based papers in the cancer survivorship literature. The exhaustive review found 198 relevant to our aim. Out of the 198 studies examining cancer survivorship found to be published by NCI-designated Cancer Centers or their affiliated hospitals in the last ten years, only 21.2% measured tobacco use as a variable. Given the clear involvement of tobacco use as a risk factor for most cancers, the review determined the variable should be a key metric in epidemiological studies. This indicated the need for increasing inclusion as a key measure in all types of cancer studies, especially those performed by National Cancer Institute-designated cancer centers.
