Abstract
To evaluate the trajectories and sustainability of health-related quality of life (HRQoL) outcomes after palliative gastrointestinal (GI) surgery and perioperative factors associated with HRQoL improvement postsurgery. BACKGROUND: Palliative patients face a wide range of physical, emotional, social, and functional challenges. In evaluating the efficacy of palliative surgical interventions, a major pitfall of traditional surgical outcome measures is that they fall short of measuring outcomes that are meaningful to patients during end-of-life. HRQoL tools may provide a more comprehensive assessment of the true value and impact of palliative surgery. METHODS: We prospectively recruit advanced cancer patients undergoing palliative GI surgery. The Functional Assessment of Cancer Therapy-General (FACT-G) questionnaire was administered before and at regular intervals after surgery. HRQoL improvement was defined as ≥4-points increment in FACT-G total score over baseline. Duration of sustained HRQoL improvement above this threshold and factors associated with varying extents of HRQoL change were evaluated. RESULTS: Of the 65 patients, intestinal obstruction was the most common indication for surgery (70.8%). The mean baseline FACT-G total score was 70.7 (95% CI: 66.3-75.1). Forty-six (70.8%) patients experienced HRQoL improvement after surgery. This HRQoL improvement was sustained over a median duration of 3.5 months and was driven mainly by improvements in patients' physical and emotional well-being. Albumin was significantly associated with the extent of HRQoL improvements (P = 0.043). CONCLUSION: A clinically significant and sustained improvement in HRQoL was observed after palliative GI surgery. Patients with higher preoperative albumin levels were more likely to experience HRQoL improvements.
