Abstract
Description
도 1b는 원발성 종양 SUV최대 및 골수 SUV평균의 유의한 상관관계를 나타내는 산포도이다. 원발성 종양 SUV최대 및 비장 SUV평균 값은 유의한 양의 상관관계를 보였으며, 상관계수 rho값은 0.323이었다. 또한, 원발성 종양의 SUV최대 값이 클수록, 즉 원발성 종양의 대사 정도가 심할수록 또는 원발성 종양의 악성도가 높게 나타날수록 비장 SUV평균 값도 증가하는 경향성을 보였다.
도 2는 원발성 종양 SUV최대, 비장 SUV평균, 골수 SUV평균, 및 간 SUV평균에 대해 재발의 예측 성능을 평가한 ROC 곡선이다. 각 최적의 컷 오프 포인트에 대하여 ROC(AUC) 미만의 면적을 계산하였다. 그 결과, 각각 0.76, 0.67, 0.57 및 0.61을 나타냈다.
도 3a는 무병 생존을 위한 Kaplan-Meier 생존 곡선을 나타낸다. 비장 SUV평균 컷 오프를 2.21로 하였을 때, 2.21 보다 높은 비장 SUV평균을 나타내는 경우 무병생존기간이 유의하게 짧은 것을 확인하였다.
도 3b는 무병 생존을 위한 Kaplan-Meier 생존 곡선을 나타낸다. 골수 SUV평균 컷 오프를 2.6525로 하였을 때, 2.6525 보다 높은 골수 SUV평균을 나타내는 경우 무병생존기간이 유의하게 짧은 것을 확인하였다.
도 3c는 무병 생존을 위한 Kaplan-Meier 생존 곡선을 나타낸다. 간 SUV평균, 컷 오프를 2.935로 하였을 때, 2.935 보다 높은 간 SUV평균을 나타내는 경우 무병생존기간이 유의하게 짧은 것을 확인하였다.
도 3d는 무병 생존을 위한 Kaplan-Meier 생존 곡선을 나타낸다. 원발성 종양 SUV최대 컷 오프를 11.27로 하였을 때, 11.27 보다 높은 원발성 종양 SUV최대를 나타내는 경우 무병생존기간이 유의하게 짧은 것을 확인하였다.
