Historically, external beam parametrial boost (EBPB) has been used in locally advanced cervical cancers to supplement radiation dose. However, it has become controversial in the era of image-guided brachytherapy. Modern 3D imaging and brachytherapy techniques have improved delineation and coverage of tumor. Outcomes with and without parametrial boost were analyzed.

局部晚期宫颈癌图像引导近距离放射治疗时代外部束宫旁增强的局部控制和使用。

从历史上看，体外束宫旁增强（EBPB）已被用于治疗局部晚期宫颈癌以补充放射剂量。然而，在图像引导近距离放射治疗时代，它引起了争议。现代 3D 成像和近距离放射治疗技术改善了肿瘤的描绘和覆盖范围。分析了有和没有宫旁增强的结果。
