Thus for this study, we extracted T-cell receptor (TCR) recombination reads from whole exome sequencing (WXS) and RNA sequencing (RNAseq) files of stomach adenocarcinoma (STAD) and soft tissue sarcoma (SARC) samples from the Cancer Genome Atlas (TCGA) and matched the corresponding TCR complementarity determining region-3 (CDR3) amino acid (AA) sequences represented by these reads to known anti-CMV CDR3 sequences. Results indicated that the recovery of both TRA and TRB recombination reads from WXS files, from either blood or tumor samples, which corresponded to AA sequences matching anti-CMV CDR3s, correlated with better survival probabilities for both STAD and SARC. However, TCR CDR3s represented by recombination reads recovered from RNAseq files and matching anti-CMV TCR CDR3 AA sequences correlated with lower survival probabilities. These results raise the question of whether exposure to CMV prior to onset or progression of cancer may lead to better survival probability whereas a potentially active T-cell response to CMV during cancer onset or progression could represent an ongoing comorbidity? In conclusion, TCR CDR3s may be an important indicator of prognosis for stomach cancer and soft tissue sarcoma and may support further research into anti-CMV CDR3s as a tool for development of immunotherapy for these cancers.</p>\u0000 </div>","PeriodicalId":8167,"journal":{"name":"Apmis","volume":"133 7","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144615180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, restricted cubic splines (RCS) results indicated a possible linear relationship between WBC counts on the 6th and 7th days and the 30-day survival status of VAP patients. Within the first week of ICU admission, both the group with initially low levels but persistently increasing WBC trajectories and the group with initially high levels but continuously decreasing WBC trajectories were associated with increased 30-day mortality in VAP patients.
