목적: 진행성 암 환자에서 악성장폐색은 구역, 구토, 통증을 비롯한 소화기계 증상을 유발하여 삶의 질을 저하시킨다. 악성장폐색의 증상 조절을 위해 octreotide를 투여한 후의 효능에 대한 보고들이 발표되었고, 저자들은 악성장폐색이 있는 환자에게 보존적 치료에 octreotide를 추가하여 투여시의 효과와 안전성을 알아보고자 하였다. 방법: 의무기록을 통하여 일반적인 치료로 호전이 없어 octreotide를 추가한 악성장폐색의 환자 29명에서 octretide를 0.1 mg을 시작으로 증상 조절될 때까지 증량하여, 약 투여 전후의 통증의 변화, 구토 횟수의 변화, 비위관 삽입환자의 경우 배액량의 변화를 조사하였다. 결과: Octreotide 투여량의 중간 값은 0.2 mg이고 0.1~0.6 mg의 범위이며, 약제 투여시점으로부터 사망까지 2일에서 103일의 범위로 중간 값은 20일이었다. 약제 투여 전의 VAS는 평균 5.6$\pm$1.2이고, 약 투여 후 VAS의 평균은 2.7$\pm$1.0이었으며 통계적으로 유의한 감소를 보였다(P<0.05). 약제 투여 전의 구토 횟수는 평균 3.6회/일$\pm$2.5이었고 약 투여 후에는 0.4회/일$\pm$0.8로 감소되었고, 통계적으로 유의한 감소를 보였다(P<0.05). 약제 투여전에 비위관 삽입 환자는 평균 975$\pm$1,083 cc/일의 배액이 확인되었고, 약 투여 후에는 평균 115$\pm$196 cc/일로 유의하게 감소하였다(P<0.05). 결론: 일반적인 약물치료에 반응이 없는 악성장폐색환자에서 octretide의 추가 투여는 효과적이며 안전하였다. 악성장폐색 환자의 증상조절을 위해서 octreotide의 추가 투여를 적극적으로 고려해야 하겠다.
Department of Internal Medicine, The Catholic University of Korea College of Medicine, Seoul, Korea Purpose: Malignant bowel obstruction causes gastrointestinal symptoms and leads to diminished quality of life in patients with advanced cancer. Several studies have shown the efficacy of octreotide for the relief of malignant bowel obstruction-related symptoms. The aim of this study is to assess the efficacy and safety of octreotide in patients with malignant bowel obstruction. Methods: We retrospectively reviewed medical records of twenty nine patients who had suffered from malignant bowel obstruction without clinical improvement of conservative care and subsequently, received octreotide treatment. Initial dosage of octreotide was 0.1 mg/day, and dose was escalated depending on the clinical effect. For each patient, we assessed visual analogue scale (VAS) of pain, number of vomiting episode, and amount of nasogastric tube drainage. Results: Median dosage of octreotide was 0.2 mg/day (range 0.1~0.6), and median duration from initial medication to death was 20 days (range 2~103). VAS before and after octreotide treatment were 5.6$\pm$1.24, and 2.7$\pm$0.96, respectively. The numbers of vomiting episode before and after octreotide treatment were 3.6/day$\pm$2.5, and 0.4/day$\pm$0.8, respectively. The mean amounts of nasogastric tube drainage before and after octreotide treatment were 975$\pm$1,083 cc/day and 115$\pm$196 cc/day, respectively. Statistically significant reduction in VAS, the number of vomiting episode and the amount of nasogastric tube drainage were observed after octreotide treatment (P<0.05). Conclusion: Administration of octreotide in patients with malignant bowel obstruction, which is uncontrolled by other medication, was effective and safe. In such clinical situations, physicians should consider to add of octreotide for symptomatic control.
