Objective: To study salvage surgery for persistent or recurrent nasopharyngeal carcinoma after irradiation failure.
Methods: A total of 84 cases underwent salvage surgery for persistent or recurrent nasopharyngeal carcinoma after irradiation failure between 1993 and 2009 was reviewed. rTNM stage: rT1 34 cases, rT2 27 cases, rT3 12 cases and rT4 11 cases; rN0 70 cases, rN1 9 cases and rN2 5 cases; No with distance metastatic. The salvage surgeries were performed using maxillary swing approach (47 cases), transcervical-mandibulo-palatal approach (21 cases), palate nasopharyngectomy (6 cases), lateral rhinotomy (7 cases), and maxillectomy (3 cases).
Results: Persistent or recurrent nasopharyngeal carcinoma after irradiation failure was resected completely in 57 patients (67.9%) and there were microscopic residual diseases in 27 patients (32.1%). The median follow-up was 27 months. Postoperative recurrence occurred in 35 cases. Thirty-six patients died of recurrence, metastasis and other diseases. The overall 5 year survival rate was 43.6%. Cox regression analysis indicated the complete resection for persistent or recurrent disease and no cervical metastasis were two independent factors affecting survival.
Conclusions: Salvage surgery for persistent or recurrent nasopharyngeal carcinoma after irradiation failure is an effective treatment.

PLUNC downregulates the expression of PD-L1 by inhibiting the interaction of DDX17/β-catenin in nasopharyngeal carcinoma.

Background: Nasopharyngeal carcinoma (NPC) is characterized by high programmed death-ligand 1 (PD-L1) expression and abundant infiltration of non-malignant lymphocytes, which renders patients potentially suitable candidates for immune checkpoint blockade therapies. Palate, lung, and nasal epithelium clone (PLUNC) inhibit the growth of NPC cells and enhance cellular apoptosis and differentiation. Currently, the relationship between PLUNC (as a tumor-suppressor) and PD-L1 in NPC is unclear.

Background: Primary pulmonary lymphoepithelial carcinoma (pLEC) is a subtype of non-small cell lung cancer (NSCLC) characterized by Epstein-Barr virus (EBV) infection. However, the molecular pathogenesis of pLEC remains poorly understood.
Methods: In this study, we explored pLEC using whole-exome sequencing (WES) and RNA-whole-transcriptome sequencing (RNA-seq) technologies.

Background: To study the efficacy and safety of Polyethylene glycolated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in the prevention of neutropenia during concurrent chemoradiotherapy for nasopharyngeal carcinoma (NPC).
Methods: This is a single-center, prospective, randomized controlled study conducted from June 1, 2021, to October 31, 2022 on patients diagnosed with locally advanced NPC. Participants were divided into an experimental group and a control group.

Background: Nasopharyngeal cancer (NPC) is a common head and neck malignant tumor, which is difficult to treat at the advanced NPC due to its occult and high metastatic potential to the cervical lymph nodes and distant organs. Low-dose radiotherapy (LDRT) is increasingly being investigated for potential cancer treatment. When combined with immune checkpoint inhibitors, LDRT has been shown to significantly improve the immune microenvironment of tumors, thereby promote the immune attack on tumor cells.

Purpose To develop and evaluate a deep learning-based prognostic model for predicting survival in locoregionally- advanced nasopharyngeal carcinoma (LA-NPC) using serial MRI before and after induction chemotherapy (IC). Materials and Methods This multicenter retrospective study included 1039 LA-NPC patients (779 male, 260 female, mean age 44 [standard deviation: 11]) diagnosed between April 2009 and December 2015. A radiomics- clinical prognostic model (Model RC) was developed using pre-and post-IC MRI and other clinical factors using graph convolutional neural networks (GCN).
