人类乳头瘤病毒阴性的头颈部鳞状细胞癌(HPV阴性的HNSCC)患者的预后比HPV阳性的HNSCC更差。在我们的研究中,我们使用了一个已发表的数据集,并调查了在分子分类的肿瘤组中丰富的微生物。我们发现,微生物特征可以区分与基因表达特征相似的缺氧/免疫表型。此外,我们确定了三种高度相关的微生物,它们具有对免疫治疗反应至关重要的免疫过程。基于三种微生物的共同丰度,分子异质性组的患者的存活率显示出显著的差异。总体而言,我们提出的证据表明,肿瘤相关微生物区系是肿瘤生态系统的关键组成部分,可能影响肿瘤微环境和免疫治疗反应。我们的研究结果需要进一步的研究来从实验上验证这些结论,这些结论对临床决策,如治疗选择具有重要影响。
Patients with human papillomavirus-negative head and neck squamous cell carcinoma (HPV-negative HNSCC) have worse outcomes than HPV-positive HNSCC. In our study, we used a published dataset and investigated the microbes enriched in molecularly classified tumor groups. We showed that microbial signatures could distinguish Hypoxia/Immune phenotypes similar to the gene expression signatures. Furthermore, we identified three highly-correlated microbes with immune processes that are crucial for immunotherapy response. The survival of patients in a molecularly heterogenous group shows significant differences based on the co-abundance of the three microbes. Overall, we present evidence that tumor-associated microbiota are critical components of the tumor ecosystem that may impact tumor microenvironment and immunotherapy response. The results of our study warrant future investigation to experimentally validate the conclusions, which have significant impacts on clinical decision-making, such as treatment selection.
