Objective: To explore the techniques, advantages and disadvantages, indications and cautions of a surgical approach for the resection of nasopharyngeal tumor.
Methods: Ten cases with nasopharyngeal tumors were recruited in this study, of them, 3 cases with residual nasopharyngeal carcinoma after chemoradiotherapy, 2 cases with cavernous angioma, 2 cases with benign mixed tumor, 1 malignant mixed tumor, 1 adenoid cystic carcinoma, and 1 chordoma. All patients underwent endoscopic resection of posteroinferior quarter part of nasal septum, and then the removal of nasopharyngeal tumors through bilateral transnasal approach.
Results: Total resection of the tumor was achieved for all cases without severe surgical complications. All cases with benign tumors, with following-up of 6-18 months, showed no recurrence. Of 6 cases with malignant tumors, with following-up of 12-48 months, 5 cases showed no recurrence, and 1 case was suspected to relapse one year postoperatively, but not with any lesion enlargement after another 6 month follow-up.
Conclusions: Posteroinferior quarter part of nasal septectomy is preferred for endoscopic resection of nasopharyngeal tumors because it can provide a panoramic view on nasopharyngeal cavity and tumors, thus, facilitating the removal of nasopharyngeal tumors.

Nasopharyngeal carcinoma (NPC) refers to a cancerous tumor that develops in the upper and side walls of the nasopharyngeal cavity. Typically, individuals are often diagnosed with the disease when it has already progressed significantly, and those with advanced NPC tend to have an unfavorable outlook in terms of response rate to targeted treatments and overall clinical survival. Various molecular mechanisms, including Myeloid-derived suppressor cells and factors like PD-L1, have been explored to enhance the outcome of NPC.

Background: Gallbladder and biliary tract cancer (GBTC) increasingly aggravates the global malignancy burden. This study aimed to evaluate the updated condition of GBTC temporal burden trends and inequalities from 1990 to 2021.
Methods: Data on GBTC were extracted from the Global Burden of Disease (GBD) 2021 study.

Nasopharyngeal carcinoma (NPC) and extranodal NK/T-cell lymphoma (ENKTL) are associated with the Epstein-Barr virus (EBV). The current study aimed to evaluate the trends in the incidence of ENKTL and NPC in Taiwan within the last 15-30 years. To assess the incidence of ENKTL from 2008 to 2021 and NPC from 1995 to 2021, an epidemiological study was performed using population-based registry data from the Taiwan Cancer Registry.

Background: Despite its crucial role in immune surveillance and cell survival of tumors, the significance of MHC antigen processing and presentation machinery (APM) is still not fully understood in head and neck squamous cell carcinoma (HNSCC). We sought to develop an APM gene score (APMGS) to predict prognosis and reveal the molecular and immune traits of the APMGS-defined subgroups in HNSCC.
Methods: Based on the APM-related genes acquired from 6 databases, 117 combined machine learning algorithms were applied to develop APMGS with The Cancer Genome Atlas (TCGA)-HNSCC database and validated with the Gene Expression Omnibus (GEO) dataset.

Ambient air pollution exposure was associated with an increased risk of incident cancer, but few previous studies have focused on the associations between ambient air pollution and nasopharyngeal carcinoma (NPC). Thus, our goal is to examine whether exposure to ambient air pollution in Hangzhou, which includes sulfur dioxide (SO), nitrogen dioxide (NO), and inhalable particles (PM), will have an impact the risk of incident cancer. We collected data on daily ambient air pollution data, climate, and daily incidence of NPC in Hangzhou from Jan 1, 2013, to Dec 31, 2022.
