Background: Oral microbiome has been associated with various cancers, including nasopharyngeal carcinoma (NPC), but its role in cancer treatment and prognosis remains largely unknown. This study aims to address the dynamic changes in oral microbiome following cancer treatment and their prognostic implications in NPC patients.
Patients And Methods: Unstimulated whole saliva samples were collected from 23 NPC patients before and after treatment, with an average of 2.
Article Synopsis
- * A study with 274 newly diagnosed lung cancer patients showed that high levels of ofCS-modified CD44 were associated with worse overall survival (OS) and progression-free survival (PFS).
- * Prognostic nomograms created from these plasma levels can predict patient survival more accurately, indicating that ofCS-modified CD44 could be a valuable independent prognostic marker in lung cancer treatment.
Article Synopsis
- A new study has developed a saliva biopsy method for detecting nasopharyngeal carcinoma (NPC), showing the potential of using oral samples for diagnosis.
- Researchers collected 907 samples, including saliva and swabs, and found significant increases in Epstein‒Barr virus (EBV) DNA methylation in NPC patients.
- The study suggests that using saliva and oropharyngeal swabs together can improve NPC detection and indicates the possibility of self-sampling for home-based screening.
Article Synopsis
- Nasopharyngeal carcinoma (NPC) is highly prevalent in Southern China, leading to significant health issues, and current EBV screening methods often result in false positives, suggesting a need for improved screening approaches.
- A Markov model was created using regional health data to compare polygenic risk-stratified screening, which targets individuals based on their 10-year absolute risk, against traditional age-based screening methods.
- Results showed that polygenic risk-stratified screening is more cost-effective for individuals aged 30-54, particularly for men, as it reduces unnecessary procedures and has a higher chance of being cost-effective than the age-based approach.
Article Synopsis
- The study explores the link between oral microbes and their potential role in developing nasopharyngeal carcinoma (NPC), revealing that these microbes can migrate from the mouth to the nasopharynx.
- It found an increased risk of NPC associated with oral-to-nasopharyngeal microbial translocation, with certain species like Fusobacterium nucleatum identified as prevalent in NPC patients.
- Additionally, the presence of these oral microbes in tumors influences the local environment and interacts with Epstein-Barr virus (EBV) loads, suggesting a complex relationship in cancer development.
Article Synopsis
- EBV (Epstein-Barr Virus) is linked to various cancers, and understanding its methylation profiles in tumor tissues is crucial for cancer research.
- A study utilizing EBV methylation capture sequencing found distinct methylation patterns in different tumor types, with significant differences identified, especially in EBVaGC compared to others.
- The research also established a diagnostic model with high accuracy for differentiating nasopharyngeal carcinoma (NPC) from nasal NKTCL, suggesting that specific EBV CpG sites may aid in cancer diagnosis and understanding EBV's role in tumor formation.
Previous studies have demonstrated strong associations between host genetic factors and Epstein-Barr virus (EBV) VCA-IgA with the risk of nasopharyngeal carcinoma (NPC). However, the specific interplay between host genetics and EBV VCA-IgA on NPC risk is not well understood. In this two-stage case-control study (N = 4804), we utilized interaction and mediation analysis to investigate the interplay between host genetics (genome-wide association study-derived polygenic risk score [PRS]) and EBV VCA-IgA antibody level in the NPC risk.
