1 ORIGINAL ARTICLE J Breast Dis 2016 December; 4(2): JBD Journal of Breast Disease 추적기간에따른유방암생존자들의디스트레스와삶의질 조한철, 김의태, 민준원 단국대학교의과대학외과학교실 Distress and Quality of Life for Breast Cancer Survivors during Follow- Up Periods in Korea Han Cheol Jo, Eui Tae Kim, Jun Won Min Department of Surgery, Dankook University College of Medicine, Cheonan, Korea Purpose: Few studies have reported postdiagnosis differences in distress and quality of life (QOL) for breast cancer (BC) survivors. Here we investigated the differences in distress and QOL for BC survivors in Korea, during follow-up. Methods: Completed questionnaires were collected from 179 BC survivors in Functional Assessment of Cancer Therapy-Breast was administered to measure the distress and Distress Thermometer and Problem List was administered to measure the QOL. Results: The mean QOL score was (standard deviation, ± 20.33). Seventy-nine patients (44.1%) with distress-test scores > 4 were assigned to the severe distress group. The patient group with higher family income had high QOL score (p= 0.008). In addition, QOL scores were significantly higher in patients who lived longer after diagnosis (p= 0.016). Patients at high TNM stage had low QOL scores (p= 0.006). Furthermore, older patients tended to have high distress scores (p= 0.028). Based on duration of the postdiagnosis period, we divided the patients into two groups. Seventy patients had a postdiagnosis period <2 years; 109 patients, postdiagnosis period 2 years. Distress score of the under-2-year group (4.26± 2.73) was significantly higher (p= 0.044) than that of the longer-than-2-year group (3.47±2.42). Conclusion: BC survivors showed improvement in physical well-being, emotional well-being, and functional well-being domain of QOL over time. However, social well-being and BC subscale score were only slightly improved over time. It is possible that cancer patients supporting programs are focused on the recently diagnosed patients or those currently undergoing treatment. Therefore, more support should be made available to long-term BC survivors.

Functional Assessment Cancer Therapy-Breast (FACT-B) 삶의질은 1993년 Functional Assessment of Chronic Illness Therapy (FACIT) 에의해개발되고한국문화에맞추어번안되어신뢰도와타당도가입증된한국어판 FACT-B 버전을이용하여측정하였다 [8]. 도구의사용은 FACIT 사이트 ( 를통해허가를받았다. 문항구성은신체적상태 (7문항), 사회적 / 가족상태 (7문항), 정서적상태 (6문항), 기능적상태 (7문항) 및유방암특이적상태 (10문항) 등총 5개로나뉘어있다. 증상이없는경우에 0점, 매우그렇다 에 4점을부여하며점수가높을수록삶의질이높음을의미한다. 본연구에서의도구신뢰도는 Cronbach s α = 0.79이었고, 신체적상태 (0.90), 사회적 / 가족상태 (0.83), 정서적상태 (0.69), 기능 자료분석 본연구에서는삶의질과디스트레스에영향을줄수있는인구 사회적요소로연령, 결혼상태, 교육정도, 종교, 직업, 경제상태, 거 주지역, 사보험및환우회여부를조사하였다. 또한, 질병관련특성 으로진단병기, 치료유형, 동반질환여부, 가족력, 경과기간에대 해확인하였다. 수집된자료는 SPSS version 19.0 프로그램 (IBM Corp., Armonk, USA) 으로분석하였다. 대상자의인구사회학적특 성과질병관련특성에따른삶의질과디스트레스의차이는 t-test, 분산분석 (analysis of variance) 을이용하여분석하였다. 결과 대상자의특성및디스트레스와삶의질정도 총대상자의수는 179 명으로, 연령대는 세가 83 명 (46.4%) 으 로가장많았다. 결혼여부는기혼이 161 명 (89.9%) 으로대부분을차 지하였고, 종교가있는경우가 98 명 (54.7%) 으로많았다. 교육정도는 고등학교졸업이 80 명 (44.7%) 으로가장많았고, 직업은 53 명 (29.6%) 이가지고있었다. 경제상태는가족월수입으로조사하였고 만원이 64 명 (35.8%) 으로가장많았다. 사보험은있는경우가 129 명 (72.1%) 으로많았으며, 환우회활동을하는경우는 73 명 (40.8%) 이 었다. 질병관련해서는진단기간은 2 년이내가 70 명 (39.1%) 으로가장 많았고, 10 년이상도 10.1% 를차지하였다. 진단병기는 1 기가 68 명 (38.0%), 2 기가 66 명 (36.9%) 으로많은부분을차지하였고동반질환 은없는경우가 127 명 (70.9%) 이었고, 유방암가족력은 15 명 (8.4%) 만 이있었다. 연구대상자의삶의질은평균 점 ( ± 20.33) 이었으며, 영역별 로 10 점기준으로보았을때, 사회적 / 가족상태가 5.36 으로가장낮 았으며, 신체적상태영역이 7.65 로가장높았다 (Table 1). 디스트레 스의경우는평균 3.78 점 (± 2.57) 이었으며, NCCN 기준에따라 4 점 Table 1.

Differences in quality of life and distress scores based on postdiagnosis period Characteristic 영역 (15.52± ± 4.17), 기능적영역 (15.56 ± ± 5.74) 은 2 년이지나면유의하게높아지는것 (p = 0.013, p = 0.032, p < 0.001) 을알수있었으나, 사회적 / 가족영역과유방암특이적영역은점수 가향상되기는하나통계적으로유의하지는않았다 (Table 4). 고찰 본연구는유방암생존자의삶의질과디스트레스정도를파악 하고진단후시간이지날수록어떤변화가있는지알아보았다. 이 번연구에서는전체적인삶의질점수는 점, 디스트레스의경 우평균 3.78 점이었으며, 시간이지나면서대부분의삶의질영역이 회복되나사회적 / 가족영역의회복은늦은것을보여주었다. 각영역의삶의질점수를보면, 신체적영역이가장높은점수를 보였고사회적 / 가족영역이가장낮았다. 같은측정도구 (FACT-B) 로삶의질을측정한국내및국외선행연구 [9,10] 와비교해보았을 때큰차이가없었다. 대부분의연구에서사회적 / 가족영역점수가 가장낮은것으로보여사회적지지및가족영역에서의배려가필 요하다는것을보여준다. 디스트레스의경우평균 3.78 점으로, 국내 선행연구 [7,10] 보다는 점정도낮게나타났으나, 국외연구 [11] 3.82 점과비슷한수준이었다.

FACT-B= Functional Assessment of Cancer Therapy-Breast. 일반적으로암생존자는진단과동시에디스트레스를받으면서 삶의질이떨어지기시작하며, 치료를받으면서현저히삶의질이떨 어지게된다 [12]. 유방암생존자의삶의질에영향을미치는요소는 나이와병기, 수술방법, 항암치료여부, 동반질환여부등이알려 져있지만, 연구마다차이가있다 [13-15]. 이번연구에서는경제상태 가좋은경우, 진단후시간이많이경과되었을경우, 그리고병기가 낮은경우가삶의질이높은것으로나타났다. 삶의질에영향을주 는디스트레스의경우는나이가많은경우에젊은생존자에비해 유의하게더높은디스트레스를보였다. 일반적으로유방암생존자 의삶의질저하위험요인으로나이가젊은경우가되어있지만, 나이가들수록심리사회적지지요소가약해지면서디스트레스가높아진다는보고가있다 [16]. 국내연구에서도오히려나이가많은유방암생존자가삶의질이낮다는보고가있었지만 [17], 본연구에서는나이에연관된삶의질차이는없었다. 거주지역의경우, 대도시 ( 만 ) 인경우에디스트레스가높은것으로나타났지만, 광역시 / 특별시 (100만이상 ) 와대도시를하나로묶어서분석한경우에는다른지역과차이가없었다. 여러선행연구에서암생존자의삶의질은진단후시간이지나면많은부분이회복되는것으로밝혀졌지만, 대부분의연구가진단후 2년까지시기에몰려있다 [4-6,9,12]. 또한, 치료중인경우나추적관찰중인경우는오히려의료진과가족들의관심과지지를받지만어느정도의시간이지나면그러한부분이부족해지면서심리적인불안감을보이는경우가있다. 또한, 유방암의경우다른고형암에비해 5년이지난경우에도재발하는경우가많아유방암생존자의경우재발에대한우려로인해시간이지나도여전히디스트레스가높은것을보여주었다 [18]. 이번연구에서는진단후 2년이내그룹과 2년이후그룹으로나누어삶의질과디스트레스변화를분석하였다. 모든영역의삶의질과디스트레스점수가호전되는것을보여주어서선행연구와같은결과를보여주었다. 하지만, 각영역을통계학적유의성으로보았을때, 사회적 / 가족영역이나유방암특이적영역은점수의상승은있었으나통계학적차이는없었다. 이것은시간이지나면유방암생존자는치료로인한증상은대부분회복되지만, 사회적 / 가족영역의회복은더딘것을보여준다. 현재유방암및암생존자들을위한사회프로그램이많이진행되고있지만, 대부분치료중인환자에국한되어있는것이사실이다. 앞으로는장기암생존자들을위한프로그램도활발히진행되어야할것으로생각되며, 가족의지지및관심도더필요할것이다. 본연구에서는몇가지제한점이있다. 첫째, 본연구에서는일부지역의생존자들만을대상으로조사가이루어졌기때문에, 이결과를토대로전체생존자에게일반화하기에는무리가있다. 둘째, 본연구는장기간의추적관찰을통해시간의흐름에따라동일한생존자의디스트레스와삶의질의변화를보는종단적연구가아닌횡단적연구이다. 셋째, 이번연구에서는삶의질과디스트레스에영향을주는것으로보고된항암치료등을포함한보조적치료의여부에따른분석이이루어지지않았다. 마지막으로삶의질을점검할수있는여러도구중에 FACT-B 한가지만으로연구를진행하였기때문에, 다른도구를이용한여러연구와비교가쉽지않다. 이번연구는이런제한점을가지고있지만, 유방암생존자의삶의질과디스트레스의일반적인결과와일정한시간후에도암생존
