PURPOSETo characterize the pattern of post-treatment quality of life (QoL) for esophageal cancer (EC) survivors and construct models predicting their long-term QoL.METHODSOn the basis of a randomized trial in an EC high-risk region in China, we interviewed 363 EC survivors and 25,245 permanent residents matched with the survivors on age, sex, and township as the baseline.QoL was measured using three-level version of European Quality of Life 5-Dimensions instrument.

We constructed piecewise mixed models estimating the QoL of EC survivors that varied by age, sex, patient type, hospital level, and therapy to ascertain QoL determinants.RESULTSThe post-treatment u11-200ps QoL of EC survivors dropped by 15.7% within the first year and recovered by 9.

3% between 1 and 9 years compared with the baseline.Therapy was found to be a determinant of QoL, and a series of therapy-specific models were fitted accordingly, which all showed the pattern of decreasing rapidly and recovering gradually.Endoscopic treatment had the least impact on post-treatment QoL (7.

5% drop within 5 years) compared with esophagectomy (12.2% drop within 1 year) and chemoradiotherapy (37.8% drop within 2 years).

The usual activities dimension showed the greatest impairment among those patients (34.4% drop within 1 year).CONCLUSIONThis community-based study described the long-term QoL trajectory for EC survivors after different therapeutic modalities and constructed models to predict therapy-specific QoL at different time points after treatment.

It provided new insights into decision making in bolia outlet gent treatment for EC from the perspective of QoL protection, offering a convenient tool for estimating quality-adjusted life-years.
