Health-related quality of life among 5-year survivors of esophageal cancer surgery: a prospective population-based study.

PURPOSE: To clarify whether health-related quality of life (HRQL) can be restored in 5-year survivors of esophageal cancer surgery. PATIENTS AND METHODS: The nationwide Swedish prospective and population-based cohort for this study consisted of patients with esophageal cancer who were treated surgically between 2001 and 2005 and were alive 5 years after surgery. The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 (EORTC QLQ-C30) and EORTC QLQ-OES18 (the disease site-specific module for esophageal cancer) were used to assess HRQL 6 months, 3 years, and 5 years postoperatively. Paired t tests were used to evaluate changes in HRQL over time. Patients' HRQL was classified as improved, stable, or deteriorated. Multivariable linear regression was used to calculate mean score difference in HRQL with 95% CIs between patients and a background population according to HRQL category.
RESULTS: Among 153 eligible patients alive after 5 years, 117 (76%) answered all HRQL assessments. Among a random sample of 6,969 Swedish adults representing the corresponding background population, 4,910 (70.5%) participated. For most patients, HRQL remained stable or improved over time, and their HRQL was comparable to that of the background population. Patients who deteriorated over time reported large and clinically significant mean score differences for all measures. For example, 5 years after surgery, physical function was stable or improved in 86% of patients and their mean score (87) was similar to that of the background population (88), but the 14% who deteriorated had a substantially lower mean score of 56.
CONCLUSION: HRQL recovers to a level comparable to that in the background population in most patients who survive 5 years after esophagectomy for cancer, although a subgroup of patients has substantially worse HRQL.
