Down syndrome (DS), a genetic disorder characterized by an extra full or partial copy of chromosome 21, results in distinctive developmental and physical features. Notably, individuals with DS exhibit a remarkable resilience against solid tumors compared to the general population, with an overall standardized incidence ratio (SIR) of 0.45, despite their increased susceptibility to hematologic malignancies [<span>1</span>]. This paradoxical observation has spurred extensive research aimed at uncovering the biological underpinnings of this natural resistance to solid cancers. Current theories suggest that the overexpression of specific genes on chromosome 21 may confer protective benefits (e.g. <i>RCAN1</i> contributes to antiangiogenic effects), and alterations in immune system function may enhance apoptosis and DNA repair pathways in individuals with trisomy 21 DS [<span>2</span>]. The well-established epigenetic effects of trisomy 21, which influence the entire genome, are another potential contributor to the reduced risk of solid tumors [<span>3</span>]. Nonetheless, these hypotheses face significant challenges, such as the potential oversimplification of complex genetic interactions and the lack of comprehensive genome-wide analyses.

The hrHPV-DNA test detects 14 high-risk HPV genotypes including the predominant hrHPV16/18, which can cause cervical abnormalities that may progress to cancer if untreated.

Tumor deposits (TD) have been identified as another histological feature with a strong prognostic impact but are currently only deemed clinically relevant in the absence of LNM [&lt;span&gt;2, 3&lt;/span&gt;]. TD are clusters of tumor cells in the fat surrounding the bowel and are often associated with nerves, vessels and lymphatic tissue, giving the cancer cells access to multiple routes of spread [&lt;span&gt;4&lt;/span&gt;].&lt;/p&gt;&lt;p&gt;To study whether TD could indeed form an alternative gateway to distant metastases, we have used polyG-based phylogenetics on formalin-fixed paraffin-embedded (FFPE) tissue to investigate the role of histologically defined TD and LNM in CRC evolution and distant metastatic spread to the liver and peritoneum.&lt;/p&gt;&lt;p&gt;We collected data from patients who were diagnosed with colorectal liver or peritoneal metastases between January 2015 and January 2022 and not previously treated with chemotherapy. DNA was isolated from the TD and LNM (Figure 1A), normal tissue (which was sampled at the edge of the resection specimen) and distant metastases. Three distinct tissue parts of the primary tumor were sampled to account for intra-tumor heterogeneity (Figure 1B), yielding a total of 480 samples (Supplementary Table S1). Polymerase chain reaction (PCR) was used to genotype up to 24 polyG regions for every sample (Supplementary Table S2). Sequentially, phylogenetic trees were constructed based on the peak distribution of all PCR results from the polyG regions using an analysis pipeline previously developed by Naxerova et al. in R software (version 4.3.1) [&lt;span&gt;5&lt;/span&gt;]. Phylogenetic trees are graphical representations of the evolutionary relationship between biological entities, in this case, the different tissue samples. After quality control of PCR results (i.e., poor quality DNA), impurity (i.e., contamination of samples with non-tumorous cells, Supplementary Figure S1), and branching confidence (i.e., values &lt; 50% were deemed unreliable), 47 CRC patients with a total of 43 individual liver metastases and 30 individual peritoneal metastases were included in the final results (Supplementary Table S3-S5). The distribution of origins (TD, LNM, primary tumor or a mix of these) was compared between the group of liver and the group of peritoneal metastases using Fisher's exact test. Potential confounding clinicopathological factors were analyzed using the Kruskal-Wallis of Fisher's exact test. &lt;i&gt;P&lt;/i&gt; values &lt; 0.05 were considered significant. Full descriptions of the materials and methods are provided in the Supplementary Materials.&lt;/p&gt;&lt;p&gt;Phylogenetic analysis showed that the primary tumor, TD, and LNM could be possible origins of liver metastases.

FGFR3 mutations in up to half of BLCAs play a well-established role in tumorigenesis, shaping distinct tumor initiation patterns and impacting the tumor microenvironment (TME). Emphasizing the importance of considering epithelial-mesenchymal transition profile and TME status, we revisit their relevance in predicting responses to immune checkpoint inhibitors in FGFR3-mutated BLCAs. This writing highlights the initially promising yet transient efficacy of the FGFR inhibitor Erdafitinib on FGFR3-mutated BLCA, stressing the pressing need to unravel resistance mechanisms and identify co-targets for future combinatorial studies. A thorough analysis of recent preclinical and clinical evidence reveals resistance mechanisms, including secondary mutations, epigenetic alterations in pathway effectors, phenotypic heterogeneity, and population-specific variations within FGFR3 mutational status. Lastly, we discuss the potential of combinatorial treatments and concepts like synthetic lethality for discovering more effective targeted therapies against FGFR3-mutated BLCA.</p>","PeriodicalId":9495,"journal":{"name":"Cancer Communications","volume":"44 10","pages":"1189-1208"},"PeriodicalIF":20.1,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cac2.12602","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142003691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
