Hypothesis
What is the impact of intratumoural microbiota on the prognosis of non-small cell lung cancer (NSCLC)?
Conclusion
Intratumoural microbiota significantly influence NSCLC prognosis, with certain microbial clusters associated with better or worse outcomes.
Supporting Evidence
- Four phyla, five classes, nine orders, 17 families, and 36 genera were found to be associated with NSCLC prognosis.
- A protective microbial cluster was identified that is associated with delayed disease recurrence.
- A harmful microbial cluster was linked to shorter survival and earlier recurrence.
- Peptococcus was identified as an independent, detrimental prognostic factor for NSCLC.
Takeaway
This study found that tiny living things called microbiota inside lung tumors can help doctors understand how well patients might do after treatment.
Methodology
The study used 16S rRNA and RNA sequencing on cancerous and adjacent normal tissues from 30 NSCLC patients to analyze microbial composition and its correlation with prognosis.
Potential Biases
Potential biases may arise from the small sample size and the specific patient population studied.
Limitations
The study is limited by its small sample size and lack of external validation cohorts.
Participant Demographics
The study included 30 patients, predominantly male (23 males, 7 females), with a median age of 64 years.
