Prognostic significance of cystic lymph nodal metastasis in nasopharyngeal carcinoma.

Background: The purpose of this study was to determine the prevalence of cystic lymph nodal metastasis (CLNM) and its prognostic value in patients with nasopharyngeal carcinoma (NPC).

Methods: A retrospective review was conducted on 257 patients with NPC, analyzing the presence of CLNM on MRI or CT scans. Oncologic outcomes were performed using the Kaplan-Meier analysis.

Relapse status as a prognostic factor in patients receiving salvage surgery for recurrent or residual nasopharyngeal cancer after definitive treatment.

Background: The purpose of this study was to determine the prognostic value of relapse status (recurrent vs residual disease) in patients receiving surgical salvage for nasopharyngeal carcinoma (NPC).

Methods: Retrospective review was conducted on 52 patients who underwent salvage surgery for locoregional relapse of NPC. Univariate and multivariate analyses were used to investigate the prognostic value of relapse status.
