Endoscopic treatment of T1a esophageal adenocarcinoma outperformed esophagectomy across a range of ages and comorbidity levels in a Markov model.
Esophagectomy produced 0.16 more unadjusted life-years, but led to 0.27 fewer quality-adjusted life-years (QALYs), in the hypothetical case of a 75-year-old man with T1aN0M0 esophageal adenocarcinoma (EAC) and a Charlson comorbidity index score of 0, reported Jacqueline N. Chu, MD, of Massachusetts General Hospital, Boston, and her associates. “[We] believe QALYs are a more important endpoint because of the significant morbidity associated with esophagectomy,” they wrote in the March issue of.

In contrast, the model portrayed the management of T1b EAC as “an individualized decision” – esophagectomy was preferable in 60- to 70-year-old patients with T1b EAC, but serial endoscopic treatment was better when patients were older, with more comorbidities, the researchers said. “For the sickest patients, those aged 80 and older with comorbidity index of 2, endoscopic treatment not only provided more QALYs but more unadjusted life years as well.”
Treatment of T1a EAC is transitioning from esophagectomy to serial endoscopic resection, which physicians still tend to regard as too risky in T1b EAC. The Markov model evaluated the efficacy and cost efficacy of the two approaches in hypothetical T1a and T1b patients of various ages and comorbidities, using cancer death data from the Surveillance, Epidemiology, and End Results (SEER) Medicare database and published cost data converted to 2017 U.S. dollars based on the U.S. Bureau of Labor Statistics’ Consumer Price Index.
