초록

목적: 고용량 인터페론-${\alpha}2b$를 이용한 악성흑색종의 면역요법은 외과적 절제술 후 현미경적 적이나 남아있는 종양의 재발을 막고 무병생존율과 전체 생존율을 높이는 것으로 알려져 있다. 저자 등은 악성 흑색종 환자군에서 외과적 절제술 후 고용량 인터페론-${\alpha}$ 면역요법을 시행한 그룹의 무병생존기간 및 전체 생존율 등을 비교 분석하여 면역요법의 치료결과를 예비 보고하고자 한다. 대상 및 방법: 2010년 2월부터 2012년 10월까지 본원에서 악성 흑색종으로 진단받고 외과적 수술 후 면역치료를 시행한 5명을 대상으로 분석 하였다. 병기는 AJCC 병기를 이용하여 판정하였으며 IIA 3예, IIB 1예, IV 1예로 나타났다. 추시기간은 최소 7개월에서 최대 32개월이었다. 면역 요법을 시행한 군에서는 먼저 유도요법으로 ${\alpha}2b$를 체표면적 당 20만 IU를 총 4주간 1주일에 5회 정주하였으며 이후 유지요법으로 체표면적당 10만 IU를 총 48주간 1주일에 3회 피하주사하였다. 이들 환자들에 대해 국소재발과 국소전이, 그리고 원격전이여부를 조사하였고 무병생존기간을 조사하였다. 결과: 인터페론-${\alpha}2b$ 면역요법을 시행한 환자군에서 추시 흉부 전산화 단층촬영 및 양전자 컴퓨터 단층촬영을 통한 평가 결과 현재까지 모두 국소 재발 및 국소전이 원격전이의 증거가 없는 것으로 나타났다. 결론: 고용량 인터페론-${\alpha}$ 면역요법 시행군에서 현재까지 종양의 국소 재발 및 전이를 막는 것으로 나타났으나 향후 궁극적인 생존율 및 무병생존율 향상이 달성되는가에 대해서는 추가적인 연구대상과 추적관찰이 필요하겠다.

Purpose: Interferon-${\alpha}2b$ using immunotherapy of malignant melanoma is known to increase the microscopic enemies that remain after surgical resection of the tumor to prevent recurrence, disease-free survival and overall survival. Authors in patients with malignant melanoma after surgical resection and high-dose interferon-${\alpha}$ immunotherapy treated group of disease-free survival and overall survival compared with the results of the treatment of immune therapy to a preliminary report. Materials and Methods: From February 2010 to October 2012 at our institution between being diagnosed with malignant melanoma after surgical immunotherapy treated patients were analyzed. Patients was evaluated using the stage AJCC stage IIA 3 cases, IIB 1 cases, IV 1 were as follows. Follow-up period of at least 7 months, and a maximum of 32 months. As maintenance therapy after the first induction therapy group underwent immunotherapy interferon-${\alpha}$ of body-surface area per 200,000 IU five times in a week for 4 weeks sedentary and body surface area a total of 48 weeks per week to 100,000 IU three times subcutaneously. These patients for local recurrence and metastases, and distant metastasis were investigated disease-free survival was investigated. Results: Interferon-evaluation through follow-up chest computed tomography (CT) and positron emission computed tomography (PET CT) in patients who underwent the ${\alpha}$ immunotherapy results above both local recurrence and metastases without evidence of distant metastases. Conclusion: The high-dose ${\alpha}2b$ immunotherapy performed in patients to prevent the local recurrence of the tumor and metastasis to the current or future ultimate survival and disease-free survival improvement achieved is additional study and follow-up will be needed.
