Is extended-field concurrent chemoradiation an option for radiologic negative paraaortic lymph node, locally advanced cervical cancer?

Background: The aim was to evaluate whether extended-field concurrent chemoradiation (EF-CCRT) leads to results better than those obtained by standard whole-pelvis concurrent chemoradiation (WP-CCRT) in locally advanced cervical cancer with radiologic negative paraaortic lymph nodes (PALNs).

Patients And Methods: A total of 102 patients with histopathologically proven squamous cell carcinoma, adenocarcinoma, or adenosquamous cell carcinoma, and radiologic negative PALN locally advanced cervical cancer, stage IIB-IVA, were accrued between July 2007 and April 2008 and were randomly assigned to WP-CCRT (50 patients) or EF-CCRT (52 patients), followed by high-dose rate brachytherapy. Data regarding the safety profile, response rates, and occurrence of local, PALN, or distant failure were recorded.
