Relationship between psychological distress and health-related quality of life at each point of the treatment of esophageal cancer.

BACKGROUND

Patients with esophageal cancer often feel depression or fear of death influenced by multiple clinical factors. This study sought to investigate the clinical factors associated with psychological distress, focusing on the influence of health-related quality of life (HRQOL) for better psychological management of patients with esophageal cancer.

METHODS

In total, 102 of 152 consecutive patients surgically treated at Toranomon Hospital met the eligibility criteria for analysis. Questionnaires designed to identify psychological distress and QOL (EORTC QLQ C-30/OES18) were administered at five time points during the treatment course. Degree of psychological distress was assessed by Hospital Anxiety and Depression Scale (HADS).

RESULTS

Patients with HADS score ≥ 11 at each visit showed significantly higher level of symptoms or problems measured by the score of EORTC QLQ C-30/OES18 compared with those with HADS score ≤ 10. Emotional status was a significant factor associated with psychological distress at all times. Although functional scales including global health status or QOL status and symptom scales associated with esophageal cancer were strongly associated with psychological distress before treatment, scales associated with changes in habitus after esophagectomy showed significant correlation with psychological distress after surgery. No significant correlation was observed between psychological distress and individual baseline characteristics, apart from history of surgery and pathological staging.

CONCLUSIONS

Psychological distress during treatment course of esophageal cancer is significantly associated with HRQOL influenced by esophagectomy. The current results may warrant prospective intervention through enhanced recovery after surgery to better manage patients undergoing highly invasive procedures for esophageal cancer.
