Investigation of the distribution of inguinal lymph nodes and delineation of the inguinal clinical target volume using ¹⁸F-FDG PET/CT.

ABSTRACT:

Objective

Radiotherapy is a crucial treatment modality for pelvic cancers, but uncertainties persist in defining the clinical target volume (CTV) for the inguinal lymphatic drainage region. Suboptimal CTV delineation may compromise treatment efficacy and result in subpar disease control. This study aimed to investigate and map the distribution of lymph node metastases (LNM) in the groin area to facilitate an improved and detailed CTV definition using ¹⁸F-fluorodeoxyglucose positron emission tomography/computed tomography (¹⁸F-FDG PET/CT).

Methods

Inguinal LNM in patients with biopsy-proven pelvic malignancies were identified using ¹⁸F-FDG PET/CT scan. The longitudinally nearest axial plane was determined based on six typical bony landmarks, a
