Long-term health-related quality of life following robot-assisted radical transmediastinal esophagectomy

The good short-term and oncological outcomes of robot-assisted radical esophagectomy have been demonstrated, although its impact on long-term health-related quality of life (HRQoL) remains to be investigated. This study aimed to assess long-term HRQoL in patients after robot-assisted radical transmediastinal esophagectomy (TME), which is characterized as non-transthoracic esophagectomy comprising a robotic transhiatal approach and a video-assisted cervical approach, and transthoracic esophagectomy (TTE).

The European Organization for Research and Treatment of Cancer generic and disease-specific modules (QLQ-C30 and QLQ-OES18), nutritional status and body composition data were prospectively collected in patients undergoing TME or TTE before and at 3, 6, 12, 18, and 24 months after surgery. The results of long-term (≥ 2 years) survivors without recurrence were compared between the two groups.

A total of 37 patients (TME; n = 18, TTE; n = 19) were included for analysis. Longitudinal survey of function scales revealed scores of physical, role, social, and emotional function to be significantly better in the TME group than in the TTE group at many points postoperatively. Markedly, the symptoms of general pain, esophageal pain, and dry mouth greatly worsened after surgery in the TTE group, but did not deteriorate in the TME group. In contrast, symptoms relating to eating difficulties, body composition data, and nutritional status did not differ between the groups over time. At 24 months after surgery, TME provided significantly higher scores of global QOL (P = 0.01) and emotional function (P = 0.01) and also resulted in significantly fewer problems of fatigue (P = 0.04), general pain (P = 0.04), insomnia (P = 0.02), and dry mouth (P = 0.03), as compared to TTE.

This study indicates that TME can provide better long-term HRQoL outcomes than TTE.
