Octreotide for palliative treatment of hepatic metastases from non-neuroendocrine primary tumours: evaluation of quality of life using the EORTC QLQ-C30 questionnaire

Background and aim: While octreotide has been used in palliative treatment of hepatocellular carcinoma and neuroendocrine tumours with good results, little is known about the possible role of this in palliative treatment of hepatic metastases. Material and methods: We present our experience from the use of octreotide in palliative treatment of symptomatic liver metastases in 16 patients (11 males, five females, age ranged 43-69 years) with proven hepatic metastases from different primary tumours (six with non-small lung cancer, four with colon carcinoma, two with primary pancreatic head carcinoma, two with prostate cancer and two with adenocarcinoma of the stomach). All patients were administered 20 mg long-acting octreotide IM (octreotide LAR) once the first day, octreotide SC 0.5 mg three times daily on days 2-14 and then 20 mg long-acting octreotide IM every month. Quality of life was assessed by using the European Organization for Research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire (QLQ-C30). Tumour response was evaluated by using ultrasonography. Results: One month after baseline, octreotide resulted in significant (P>0.01, Wilcoxon test) improvement and stabilization of all major related EORTC QLQ-C30 parameters such as global quality of life, pain, fatigue, insomnia, appetite loss as well as physical, emotional, cognitive, social and role functioning. Except for mild hyperglycaemia in six out of 16 patients and mild gastrointestinal complications in one patient, no other severe side effect due to octreotide was reported. Two patients died two months after the initiation of the study due to generalized metastatic disease, while the remaining 14 patients were still alive seven months after the initiation of the study. The hepatic metastases were stabilized and no new lesions were detected by ultrasonography. Conclusions: Although further studies are warranted, we consider the use of octreotide a good alternative in palliative treatment of symptomatic liver metastases in patients with end-stage malignant disease.
