CSDE Affiliate Kemi Doll (Obstetrics and Gynecology) and co-authors recently published a research article in Epidemiology titled, “Evaluating Data Sources for Monitoring Guideline-Concordant Endometrial Cancer Treatment Among Older Adults.” Guideline-concordant care, treatment consistent with recommendations based on tumor characteristics, is critical for endometrial cancer survival, but cancer registry data typically assess concordance based only on whether a recommended treatment was received, without capturing details like timing, amount, and duration needed to judge treatment adequacy. Using SEER-Medicare linked data on older patients diagnosed with endometrial cancer between 2000 and 2019, the authors compared guideline-concordance classifications based on Medicare claims, which capture both treatment receipt and adequacy, against classifications based on SEER registry data, which capture receipt alone. They found that guideline-concordant care appeared more frequent in SEER than in Medicare claims for both surgery (88.2% vs. 79.8%) and adjuvant treatment (85.4% vs. 71.6%), with only moderate agreement between the two data sources. The findings suggest that SEER-based measures relying solely on treatment receipt may overestimate guideline-concordant care for older endometrial cancer patients by failing to account for treatment adequacy.
