Among the most widely used instruments to assess quality of life (QOL) in patients with cancer are the European Organization for Research and Treatment of Cancer core questionnaire (EORTC QLQ-C30) and the Functional Assessment of Chronic Illness Therapy, cancer instrument (FACT-G). This study compared these approaches in patients who had undergone esophagectomy for cancer. The EORTC core questionnaire and esophageal module and the FACT-G and esophageal scale were completed by 57 patients. Missing data, relationships between QOL scales and analyses of patients' preferences were examined. There were 14/2736 (0.5%) missing items from EORTC questionnaires and 45/2565 (1.8%) from FACT instruments (p <0.01). Relationships between corresponding generic EORTC and FACT scales were average to good (r > 0.57) except for the social function scale (r = 0.01). EORTC symptom scores were moderately correlated with the FACT general scale, but poorly related to the FACT esophageal scale (r <0.28). EORTC swallowing scores were moderately correlated with all FACT scales. The FACT-E and EORTC QLQ-C30 measure assess similar generic aspects of QOL (except social function). EORTC esophageal symptom scores relate poorly to FACT esophageal scales, except for swallowing. Choice of QOL measure after esophagectomy for cancer depends upon outcomes of interest. Future studies will determine which instruments are appropriate in each context.
