内容記述 |
Background: The wide adoption of intensity-modulated radiotherapy (RT) renders an extended neck position unnecessary. In this study, the appropriate craniocaudal border of the retropharyngeal lymph node (RPLN) was assessed based on diagnostic and RT images in patients with hypopharyngeal carcinoma (HPC) for recommendation of appropriate target volume for elective nodal irradiation (ENI). Methods: Two board-certified radiation oncologists evaluated the craniocaudal spread of RPLN metastases (RPLNMs) and the position of the hyoid bone using magnetic resonance images (diagnostic position) and RT-planning computed tomography simulator images (RT position with neck extension). Results: Of the 154 patients in whom 308 sides were assessed, 19 (12.3%) were diagnosed with RPLNMs in 24 (7.8%) sides. The cranial border of the RPLNMs was found above the hard palate on 3 (1.0%) and 1 (0.3%) side, between the hard palate and cranial edge of the C1 body on 10 (3.2%) and 13 (4.2%) sides, and at the C1 body on 11 (3.6%) and 10 (3.2%) sides in the diagnostic and RT positions, respectively. The caudal border of the RPLNMs was observed between the hard palate and caudal edge of the C2 body on 22 (7.1%) and 22 (7.1%) sides, at the C2/3 disk level on 1 (0.3%) and 1 (0.3%) side, and at the C3 body level on 1 (0.3%) and 1 (0.3%) side in the diagnostic and RT positions, respectively. In the 19 patients with RPLNMs, the most common level of the caudal edge of the hyoid bone body was at the C4 body in 10 (52.6%) and C3 body in 8 (42.1%) patients in the diagnostic and RT positions, respectively. Conclusions: RPLNMs above the hard palate and below the C2/3 disk level extremely rarely develop in patients with HPC. The cranial edge level of the hyoid bone varied significantly among treatment positions. Regardless of the treatment position, the cranial and caudal borders of the RPLN for ENI should be defined as the hard palate and cranial edge of C3, respectively. |
