초록
목 적: 비소세포폐암(Non-Small Cell Lung Cancer, NSCLC) III, IV기 환자의 방사선 치료 시 Shell-Type Pseudo Target의 유무에 따른 IMRT 치료계획의 유용성을 알아보고자 한다. 대상 및 방법: NSCLC III, IV기 환자 22명을 대상으로 Shell-Type Pseudo Target이 있을 때와(SPT) Shell-Type Pseudo Target이 없을 때(WSPT) 각각의 세기변조방사선치료(Intensity-Modulated Radiation Therapy, IMRT)계획을 세운 후, 선량-체적 히스토그람(Dose-Volume Histogram, DVH) 분석을 통해 종양 표적 내의 균일성 지수(Homogeneity Index, HI), 종양 표적에 대한 선량조형 지수(Conformity Index, CI), 척수 최대선량(Spinal Cord Maximum Dose), 식도에 대한
Purpose: The objective of this study was to investigate the usefulness of an IMRT treatment plan according to whether there was a shell-type pseudo target during radiation therapy for patients in Stage III or IV of non-small cell lung cancer (NSCLC). Materials and Methods: After setting an IMRT (Intensity-Modulated Radiation Therapy, IMRT) plan for when there was a shell-type pseudo target (SPT) and when there was none (WSPT) with 22 patients in Stage III or IV of NSCLC, the investigator analyzed dose-volume histograms (DVHs) and made assessment with dosimetric comparisons such as homogeneity index (HI) inside the tumor target, conformity index (CI) of the tumor target, spinal cord maximum dose, Esophagus
