Health-Related Quality of Life After Surgery for Small Intestinal Neuroendocrine Tumours.

Abstract

Overall survival for patients with small intestinal neuroendocrine tumours (siNETs) is long, even with metastatic disease, making quality of life issues relevant. The impact of surgery on quality of life is not known. We investigated determinants of health-related quality of life in patients who had undergone surgery for a siNET. Patients operated for a siNET between 1998 and 2016 at Skåne University Hospital (Lund, Sweden), who were alive in February 2017, were sent two questionnaires constructed by the European Organisation for Research and Treatment of Cancer (EORTC QLQ-C30, EORTC QLQ-GINET21). Global quality of life, physical function, disease-related worries, diarrhoea and endocrine symptoms were evaluated with linear and logistic regression in relation to patient-, tumour- and treatment-related factors. Statistical analysis was performed using STATA 11®. One hundred patients (84%) completed the questionnaires. Women had worse global quality of life (p = 0.019), more disease-related worries (p < 0.001) and endocrine symptoms (p = 0.017) than men. Older age was associated with more disease-related worries (p = 0.007), but fewer endocrine symptoms (p = 0.034). Non-symptomatic tumour versus symptomatic tumour (p = 0.002), and treatment with somatostatin analogues versus no treatment (p = 0.040) were associated with less diarrhoea. Small versus large bowel resection was associated with better global quality of life (p = 0.036) and physical function (p = 0.035). Male gender, younger age, treatment with somatostatin analogues, non-symptomatic tumour, and small intestinal surgery rather than large bowel surgery were associated with better quality of life.
