A cancer diagnosis may have deleterious effects on health-related quality of life (HRQOL) as adults age. This study examined differences in HRQOL between cancer and matched noncancer Medicare beneficiaries over 65, within and across two time periods. We used novel matching methods on data from the Surveillance, Epidemiology and End Results (SEER)-Medicare Health Outcomes Survey (MHOS) data resource. We matched SEER-MHOS respondents with cancer from a recent period (2015–2019) to respondents with cancer from an earlier period (2008–2012). We then matched these two cohorts, without replacement, to contemporary cohorts without cancer diagnoses. We estimated Veteran's RAND 12-Item Short Form Survey Physical Component Summary (PCS) and Mental Component Summary (MCS) scores for all cohorts. Our analysis found significantly higher mean MCS scores in the recent period for those with cancer relative to the recent noncancer control group. Breast and lung cancer presented positive and statistically significant trends. We found statistically insignificant differences in PCS scores between the two time periods. No cancer sites had different PCS scores over time compared with the comparison group. Mental health for those with cancer improved more between 2008 and 2019 than a matched noncancer comparison group. Physical health remained stable across time. These findings highlight the importance of including a matched noncancer group when evaluating HRQOL outcomes. SEER-MHOS respondents with cancer report stable PCS scores across 15 years of data and higher MCS scores relative to noncancer controls.
