| 参加者背景/Baseline Characteristics | 対象は男性23人、女性18人で年齢中央値は66歳、計41人63結節が対象となった。 | This study included 23 men and 18 women, with a median age of 66 years.
A total of 63 lesions were included in the study. There were four cases in which additional PBT was performed for intrahepatic recurrence after a previous PBT. Two patients underwent additional PBT for one lesion, and two patients underwent additional PBT for two lesions. |
||||||
| 参加者の流れ/Participant flow | 線量分割は腫瘍のサイズ、位置によって決定された。
腸管近接腫瘍は2-2.4Gy(RBE)、肝門部近接腫瘍は3.2-4Gy(RBE)、腸管肝門から距離のある辺縁腫瘍は6-8Gy(RBE)で治療された。 |
The dose and fractionation of PBT were determined according to tumor location and size. Considering the location of the tumor and adjacent organs, we modified the dose per fraction to 2-2.4 GyE for the adjacent GI tract type, 3.2-4 GyE for the adjacent hilar region type, and 6-8GyE for the type with the hepatic periphery area away from the GI tract. | ||||||
| 有害事象/Adverse events | Grade3以上の合併症はなし。 | No grade 3 or higher AEs were observed. | ||||||
| 評価項目/Outcome measures | 主要評価項目:2年局所制御率
局所制御にかかわると思われる因子、肝転移の同時性・異時性、腫瘍サイズ、1回線量、BED10、腸管と腫瘍の距離、V dose (D)98% BED10, PTV dose (D)2cc BED10, CTV D98%BED10, CTV D2cc BED10, GTV D98%BED10, GTV D2cc BED10、照射前・中・後の化学療法について検討した。 |
Primary endpoint: 2-year LC rate
Factors that may be related to LC, such as synchronous or metachronous liver metastases, tumor size, fraction size, biologically effective dose (BED10), distance from the lesion to the GI tract, PTV dose (D)98% BED10, PTV dose (D)2cc BED10, CTV D98%BED10, CTV D2cc BED10, GTV D98%BED10, and GTV D2cc BED10, as well as the presence or absence of prior, concurrent, and post-PBT chemotherapy, were investigated. Since our study included various dose sizes and fractionation schemes, we further calculated the biologically effective dose (BED). |
