AI Article Synopsis
- Nasopharyngeal carcinoma (NPC) linked to Epstein-Barr virus (EBV) expresses specific microRNAs (miRNAs), which show varying efficacy in diagnosing NPC.
- A study evaluated these miRNAs using quantitative polymerase chain reaction on plasma samples from NPC patients and noncancer individuals.
- Results indicated certain miRNAs were significantly elevated in both primary and recurrent NPC cases, with BART19-5P being the most effective for identifying NPC, even when traditional EBV DNA tests were negative.
Article Abstract
Background: Nasopharyngeal carcinoma (NPC) latently infected by Epstein-Barr virus (EBV) expresses 40 EBV BART microRNAs (miRNAs). Difference in diagnostic efficacy of these miRNAs on NPC detection was observed. Here, we performed a comprehensive evaluation on the efficacy of these miRNAs.
Methods: Quantitative polymerase chain reaction was performed on plasma nucleic acid isolated from patients with NPC and noncancer donors.
Results: For primary NPC, BART2-5P, BART6-3P, BART7-3P, BART7-5P, BART9-5P, BART11-3P, BART17-5P, and BART19-5P were significantly elevated. For recurrent NPC, plasma levels of BART2-3P, BART2-5P, BART5-3P, BART5-5P, BART6-3P, BART8-3P, BART9-5P, BART17-5P, BART19-3P, and BART20-3P were significantly increased. Area under curve (AUC) analysis showed that BART19-5P had the best performance to identify NPC which was serologically EBV DNA undetectable. For recurrent NPC, BART8-3P and BART10-3P had highest AUC value for identifying cancer in EBV DNA undetectable plasma.
Conclusion: Our data supported the use of circulating EBV miRNAs in NPC and recurrent NPC detection.

Although the majority of patients with nasopharyngeal carcinoma (NPC) present with early-stage or locoregional disease that can be treated with definitive radiotherapy, approximately 20% of patients experience disease recurrence, and 15% present with metastatic disease that is not amenable to curative therapy. Management of patients with recurrent or metastatic (r/m) NPC who are not candidates for local salvage therapy is challenging in Canada, as there is uncertainty in extrapolating evidence that is largely generated from Southeast China to non-endemic regions such as Canada. Currently, treatment options in Canada are limited to chemotherapy regimens that can only achieve short-term response and prolongation of survival.

Background: There is no consensus regarding the optimal regimen for metastatic nasopharyngeal carcinoma (dmNPC). Locoregional intensity modulated radiotherapy (LRRT) following palliative chemotherapy (PCT) has been shown to prolong the overall survival (OS) and improve the progression-free survival (PFS) of patients with dmNPC, compared with PCT alone. However, patients with a high tumor burden do not benefit from additional LRRT, which inevitably results in toxicity.

Purpose: Patients with nasopharyngeal carcinoma (NPC) experiencing locoregional recurrence concomitant with distant metastases (rmNPC) after initial treatment represent a unique subgroup with significant management challenges. This study aimed to evaluate overall survival (OS) in rmNPC patients treated with systemic therapies with or without radiotherapy.
Methods: This retrospective multicenter study included patients with locally recurrent and metastatic NPC from five hospitals.

Objectives: Patients with nasopharyngeal carcinoma (NPC) are prone to malnutrition, which leads to deterioration of health. This study is to clarify the effect of Artificial intelligence (AI)-assisted home enteral nutrition (HEN) management mode on the health status of patients with stage III to stage IV NPC after 3 years of treatment, and to provide a new strategy for improving the quality of life of patients.
Methods: Patients with stage III ~ IV NPC were determined whether to accept AI-assisted HEN management according to voluntary principle.

Background: Although the spatial heterogeneity of glioblastoma (GBM) can be clearly mapped by the habitats generated by magnetic resonance imaging (MRI), the means to accurately predicting the spatial location of local recurrence (SLLR) remains a significant challenge. The aim of this study was to identify the different degrees enhancement of GBM, including the nontumor component and tumor component, and determine their relationship with SLLR.
Methods: A retrospective analysis was performed from three tertiary medical centers, totaling 728 patients with 109 radiation-induced temporal lobe necrosis (TLN) of nasopharyngeal carcinoma (NPC) and 619 with GBM.
