Purpose: A prospective phase II trial was conducted to evaluate the effectiveness and toxicity of regional hyperthermia and whole liver irradiation (WLI) for numerous chemorefractory liver metastases from colorectal cancer. Materials and Methods: Enrolled patients had numerous chemorefractory hepatic metastases from colorectal cancer. Five sessions of hyperthermia and seven fractions of 3-gray WLI were planned. Health-related quality of life (HRQoL) was determined using the Korean version of the European Organization for Research and Treatment of Cancer quality of life questionnaire C-30 and the Functional Assessment of Cancer Therapy-Hepatobiliary version 4.0. Objective and pain response was evaluated. Results: A total of 12 patients consented to the study and the 10 who received WLI and hyperthermia were analyzed. WLI was completed as planned in nine patients and hyperthermia in eight. Pain response was partial in four patients and stable in four. Partial objective response was achieved in three patients (30.0%) and stable disease was seen in four patients at the 1-month follow-up. One patient died 1 month after treatment because of respiratory failure related to pleural metastasis progression. Other grade III or higher toxicities were detected in three patients; however, all severe toxicities were related to disease progression rather than treatment. No significant difference in HRQoL was noted at the time of assessment for patients who were available for questionnaires. Conclusion: Combined WLI and hyperthermia were well tolerated without severe treatment-related toxicity with a promising response from numerous chemorefractory hepatic metastases from colorectal cancer.

박영숙(YoungSuk Park) 대한스트레스학회 2014 스트레스硏究 Vol.22 No.4

본 연구는 일개 국립원격대학의 간호학과 학생을 대상으로 간호사의 지각된 스트레스유형, 신체증상, 행복의 특성과 이들 간의 관계를 검증하였다. 우리나라 5개 도시에 거주하는 총 272명의 자료를 분석한 결과, 당면과제 차원의 스트레스가 대인관계 차원의 스트레스 보다 더 높게 나타났다. 당면과제 차원에서는 경제적 스트레스가 가장 높았으며, 학업스트레스, 장래문제, 가치관 문제의 순으로 지각된 스트레스 정도가 높았다. 대인관계 차원의 스트레스에서는 가족관계요인이 가장 높았으며, 이성 및 배우자 관계가 두 번째로 높게 나타났다. 학업중인 간호사가 지각하는 신체 증상은 두통관련 증상이 가장 높았으며, 수면관련 증상이 두 번째로 높게 나타났다. 또한 신체증상정도에 따라 상, 중, 하 집단으로 나누어 지각된 스트레스 정도와 행복정도를 비교하였을 때 신체증상이 가장 높은 상위 집단이 중, 하위 집단에 비해 유의하게 스트레스정도가 높고, 행복정도는 낮게 나타났다. 간호사의 행복정도는 행복도 불행도 아닌 ‘보통이다’는 15.8%, ‘조금 행복한’대상자는 41.2%, ‘행복한’대상자는 37.1%, ‘굉장히 행복한’대상자는 2.9%이었으며, 스트레스, 신체증상, 행복 간에 유의한 상관관계를 나타냈다. 간호사의 건강과 행복을 향상시키기 위해 이들의 신체증상들을 스크리닝하여 조기에 중재하는 프로그램들을 개발하여 적용할 것을 제언한다.
