We retrospectively reviewed 23,414 colorectal neoplasia cases diagnosed at West China Hospital between November 2008 and June 2023.

Multivariable logistic regression was used to evaluate the independent association between early-onset status and deficient mismatch repair (dMMR). Compared with LOCRC, EOCRC showed less favorable clinicopathological features, including higher proportions of poor differentiation, T4 tumors, nodal involvement, and advanced TNM stage. EOCRC also had a significantly higher prevalence of dMMR.

Epidemiological studies increasingly support this association, particularly for early-life adiposity and persistent metabolic dysfunction. Most EOCRC cases are sporadic, indicating that environmental and lifestyle-related exposures likely play a major role. Among these, obesity may be especially important because it links systemic metabolic stress with intestinal inflammation, microbial imbalance, and epigenetic change. However, the mechanisms through which obesity promotes early colorectal carcinogenesis are still not fully defined. In this review, we examine how obesity may shape EOCRC development across four interacting domains: chronic inflammation, metabolic reprogramming, gut microbiota dysbiosis, and epigenetic remodeling.

Tremendous developments in science and medicine have been seen and reported during the history that passed since then, and many changes have taken place in the way how we observe, conduct, publish, and rank the importance of science. Many of these changes have increased our knowledge immensely and led to iconic changes and improvements for humankind, for example for the diagnosis, treatment, or the prevention of cancer.</p><p>However, some developments in the more and more professionalized world of publishing and selling research have also given rise to concern. In this Editorial, we would like to bring attention to a particular development in publication practice that we consider worrisome, which seems to become an increasing trend within habits of acknowledging and citing, or rather not citing, earlier pioneering references within scientific original publications and reviews. Specifically, during the last years it has become evident that a growing number of publications tend to cite mainly recent publications in the field and particularly recent reviews that, themselves, frequently rely on citations of the latest previous reviews. Thereby, they tend to ignore and miss seminal papers that have been published in the past by the scientific pioneers in the respective field.</p><p>As an example, in a pioneering phase starting at the end of the 1980s and lasting through the 1990s, many pioneers in the field discovered, and described in utmost detail, the essential molecular function of tumor-associated proteases in all major steps of the metastatic cascade of cancer cells. Certainly, also the <i>International Journal of Cancer</i> took its part in the early publications on this topic. Some of the proteases, especially the urokinase (u-PA) system with u-PA, the receptor u-PAR, and the inhibitor PAI-1, were shown at this time to be highly relevant, not only for migration, invasion, metastasis, and associated molecular signaling, but also for patient survival, prognosis, minimal residual disease, or tumor recurrence. This knowledge was driven by many protagonists in Europe, for example, the Finsen Laboratory Denmark, basic, translational and clinical research groups in Germany, Italy, the Netherlands, and further European countries, as well as groups in the United States (e.g., [<span>1-26</span>], and briefly reviewed again recently in [<span>27</span>]). This list of publications is by far not complete and many further publications by these and further groups were published at these early times. While the u-PA/u-PA-R system seems to regain international attention at present, in many recent publications on this topic (e.g., [<span>28, 29</span>]), however, the many pioneering pieces of work of the early phase mentioned above are rather ignored, and acc","PeriodicalId":180,"journal":{"name":"International Journal of Cancer","volume":"159 10","pages":"2377-2380"},"PeriodicalIF":4.9,"publicationDate":"2026-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ijc.70685","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148663004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
