Abstract
Background : Small cell lung cancer represents approximately 20% of all carcinomas of the lung, and is recognized as having a poor long term outcome compared to non-small cell lung cancer. Therefore, this study investigated the prognostic factors in small cell lung cancer patients in order to improved the survival rate by using the proper therapeutic methods. Material and method : The clinical data from 394 patients who diagnosed with small cell lung cancer and treated from 1993 to 2001 at the Kosin University Gospel Hospital, were analyzed. Result : There were 314 male patients (79.7%), and 80 female patients (20.3%). The number of those with limited disease was 177 (44.9%), and the number of those with extensive disease was 217 (55.1%). Overall, 366 out of 394 enrolled patients had died. The median survival time was 215 days (95% CI : 192-237days). The disease stage, Karnofsky performance state, 5% body weight loss for the recent 3 months, chemotherapy regimens, and the additive chest radiotherapy were identified as being statistically significant factors for the survival time. The median survival times of the supportive care group, one anticancer therapy, and two or more treatment groups were 17 days, 211 days, and 419 day, respectively (p<0.001). These data emphasize the importance of anticancer treatment to improve survival time for patients. The group of concurrent chemoradiotherapy (30 patients) showed significantly longer survival time than the group given sequential chemoradiotherapy (55 patients) (528 days versus 373 days, p=0.0237). The favorable prognostic factors of laboratory study were groups of leukocyte =8,000/mm3, ALP=200 U/L, LDH=450 IU/L, NSE=15 ng/mL, s-GOT=40 IU/L. In extensive disease, there was no difference according to the number of metastatic site. However, the median survival time of patients with ipsilateral pleural effusion had longer than patients having other metastatic sites. According to the survey periods, three groups were divided into 1993-1995, 1996-1998, and 1999-2001. The median survival time was significantly prolonged after 1999 in comparison to previous groups (177 days, 194 days, 289 days, p=0.001, 0.002, respectively). Conclusion: Disease stage and 5% body weight loss for recent 3 months at diagnostic state were significant prognostic factors. In addition, the performance status, serum ALP, LDH, NSE, CEA levels also appear to be prognostic factors. The survival time of those patients with small cell lung cancer has been prologned in recent years. It was suggested that the used of the EP (etoposied and cisplatin) chemotherapy method and concurrent chemoradiotherapy for patients with a limited stage contributed to the improved survival time.
연구배경 : 소세포폐암은 전체 폐암의 약 20%를 차지하며, 비소세포암에 비해 예후가 불량한 것으로 알려져 있다. 하지만, 최근 치료 효과가 점차 좋아지면서 생존율이 향상되고 있으며, 환자들의 적절한 치료를 위해 소세포폐암 환자의 생존 기간과 연관된 예후인자를 조사하였다. 방법 : 1993년에서 2001년까지 고신대학교 복음병원에서 소세포폐암으로 진단 및 치료받은 입원 환자 중에서 추적 경과 관찰이 가능한 394명의 의무기록을 바탕으로 예후 인자들의 생존기간을 후향적조사 분석하였다. 결과 : 남자가 314명(79.7%), 여자 80명(20.3%), 제한기 177명(44.9%), 확장기가 217명(55.1%)이었다. 이들 중 사망이 확인된 경우는 366명이었으며 중앙 생존기간은 215일이었다. 예후인자 중에서 병기, 전신 활동도, 최근 3개월간의 5% 체중감소, 항암 치료 여부, 항암 화학 약제 종류, 부가적 방사선 치료여부가 생존 기간의 연장과 통계적으로 유의하였다. 치료 여부에 따른 분석에서 대중 요법만 받은 환자의 중앙 생존 기간은 71일, 한가지의 암 치료만 받은 경우는 211일, 두 가지 이상 항암 치료를 받은 경우는 419일로 치료에 따라서 의미 있게 생존 기간이 연장되었다(p<0.000 각각). 항암화학요법과 방사선 치료를 같이 시행받은 환자들 중에서 조기동시 항암 화학 방사선 치료 군 (30명)은 지연교대 항암 화학 방사선 치료 군 (55명)보다 중앙생존기간이 유의하게 길었다(528일 대 373일, p=0.0237). 검사실 지표로는 백혈구
