We examined patient outcomes after Gamma Knife stereotactic radiosurgery (GKSRS) salvage therapy for recurrent high-grade gliomas (HGGs) to determine whether tumor grade or lesion size affected overall survival (OS) and progression-free survival (PFS).
This single-center retrospective study assessed radiographic response and clinical outcomes following GKSRS salvage treatment of recurrent malignant gliomas (January 2005-March 2014).
A total of 121 patients (67 female) with 132 tumors were treated. Median (range) PFS was 4.7 (3.9-5.4) months for the cohort, 6.8 (4.6-8.9) months for initial grade 2 tumors, 4.2 (1.9-6.5) months for initial grade 3 tumors, and 4.3 (3.7-4.9) months for initial grade 4 tumors. Patients with small lesions (≤6.7 cm; n = 53) had significantly longer median (range) PFS (6.8 [4.8-8.8], P=0.02).
GKSRS offers meaningful salvage therapy with minimal morbidity in appropriately selected patients with focally recurrent HGGs.
我们研究了伽玛刀立体定向放射外科手术(GKSRS)挽救性治疗复发性高级别胶质瘤(HGG)后的患者预后,以确定肿瘤分级或病变大小是否影响总生存期(OS)和无进展生存期(PFS)。
这项单中心回顾性研究评估了GKSRS挽救性治疗复发性恶性胶质瘤后的影像学反应和临床结果(2005年1月至2014年3月)。
共治疗了121例患者(67例女性),有132个肿瘤。该队列的中位(范围)PFS为4.7(3.9 - 5.4)个月,初始2级肿瘤为6.8(4.6 - 8.9)个月,初始3级肿瘤为4.2(1.9 - 6.5)个月,初始4级肿瘤为4.3(3.7 - 4.9)个月。病变较小(≤6.7 cm;n = 53)的患者中位(范围)PFS显著更长(6.8 [4.8 - 8.8],P = 0.02)。
对于经过适当选择的局灶性复发性HGG患者,GKSRS提供了具有最小发病率的有意义的挽救性治疗。
