Identifying and describing cancer survivors: Implications for cancer survivorship research and clinical care

Background Gathering information directly from cancer survivors has advanced our understanding of the cancer survivorship experience. However, it is unknown whether surveys can distinguish important subgroups of cancer survivors. This study aimed to describe the current landscape of survey questions used to identify and describe cancer survivors in national cross-sectional studies. Methods Using publicly available databases, the authors identified national cross-sectional surveys used in the United States within the past 15 years that included a question on self-reported history of cancer. After abstracting questions and response items used to identify cancer survivors, they conducted a descriptive analysis. Results The authors identified 14 national cross-sectional surveys, with half administered to the general population and the other half administered to cancer survivors. The most common question used to identify cancer survivors was Have you ever been told by a doctor or other health professional that you had cancer? Most surveys had questions asking participants to identify a single cancer type (n = 11), multiple prior cancer diagnoses or types (n = 11), and the time from diagnosis (n = 12). Treatment questions varied from active treatment status to specific treatments received. Questions addressing cancer stage (n = 2), subtypes (n = 1), metastatic status (n = 3), and recurrence (n = 4) were less frequently included. Conclusions There is no standard method for assessing self-reported cancer history, and this limits the ability to distinguish among potentially important subgroups of survivors. Future cross-sectional surveys that capture nuanced data elements, such as cancer types, stages/subtypes, metastatic/recurrent status, and treatments received, can help to fill important gaps in cancer survivorship research and clinical care.

Automated summary

This study examined survey questions used to identify and describe cancer survivors in national cross-sectional studies in the US over the past 15 years. It found that there is no standard method for assessing self-reported cancer history, which limits the ability to distinguish important subgroups of survivors. Future surveys capturing detailed data on cancer types, stages/subtypes, metastatic/recurrent status, and treatments received could help fill important gaps in cancer survivorship research and clinical care.
