Nasopharyngeal carcinoma is commonly advanced at diagnosis. In this study we evaluated the clinical presentation, diagnostic delay and factors affecting delay in nasopharyngeal carcinoma. Data were collected prospectively for 307 newly diagnosed patients, including detailed demographic data, disease history, health care consultations and referral process. Diagnostic delay was classified as patient, professional and overall. Neck lump and nasal obstruction were the commonest presenting symptoms. There was a significant association between delay time of > or = 3 months and advanced stage. Patient's age and otological symptoms were associated with increased overall delay time. Advanced clinical stage at diagnosis was associated with paitents' sociodemographic characteristics.

Affiliated Hospital of North Sichuan Medical College, Nanchong, Sichuan, China.
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).

Objective: To observe the clinical efficacy of Dendrobium officinale in the treatment of radiotherapy-induced oral mucositis in nasopharyngeal carcinoma patients, and to explore its regulating effect on immune function and oral microbiota by comparing immune-related factors and oral microbiota before and after the intervention.
Methods: We conducted a randomized double-blinded controlled trial in Zhejiang Cancer Hospital. Sixty patients with nasopharyngeal cancer combined with radiotherapy-induced oral mucositis were randomly divided into a study group and control group, with 30 cases in each group The study group used compound vitamin B12 solution and Dendrobium tea drink, and the control group simply used compound vitamin B12 solution rinse.
A fishnet between nasopharyngeal carcinoma and resistance: the competing endogenous RNA network.

Chemotherapy and radiotherapy (chemo-/radiotherapy) have advanced as the main treatment modalities for nasopharyngeal carcinoma (NPC), improving patient survival rates. However, chemo-/radiotherapy resistance in NPC cells has emerged as a key factor contributing to poor prognosis. Recently, competing endogenous RNA networks (ceRNETs) have garnered attention for their potential clinical value in studying chemo-/radiotherapy resistance.
