A large longitudinal study, now in its 12th year, has revealed an additional, devastating trait: three of every four documented retriever deaths so far have been linked to cancer—by far the highest rate for any breed and among the highest rates of any animal. Of those cancer deaths, 70% are due to hemangiosarcoma, an aggressive blood vessel malignancy that is almost always fatal except for an uncommon cutaneous subtype.&lt;/p&gt;&lt;p&gt;If cuddlier than the unusually cancer-resistant rodents known as naked mole-rats, golden retrievers are at the opposite end of the susceptibility spectrum, making them another focal point of research. Teasing out cancer-associated factors, researchers say, could help to improve the beloved dogs’ longevity—as well as our own.&lt;/p&gt;&lt;p&gt;The Denver-based Morris Animal Foundation launched the biggest research effort to date, the Golden Retriever Lifetime Study, in 2012.&lt;span&gt;&lt;sup&gt;1&lt;/sup&gt;&lt;/span&gt; Veterinary researchers there enrolled 3044 privately owned dogs throughout the United States (all between 6 months and 2 years of age) to investigate not only the incidence but also environmental and genetic risk factors for cancers and other diseases, such as cognitive decline and osteoarthritis. With the oldest participants now turning 14 years old, Julia Labadie, DVM, PhD, MSPH, the study’s principal investigator, says that studying aging in dogs has emerged as an unanticipated additional goal.&lt;/p&gt;&lt;p&gt;“We have now a cohort of pretty old golden retrievers,” she says, noting that a significant fraction of those survivors could die of non-cancer causes. “So I think there’s a lot of questions that we can answer about the dogs that don’t get cancer and the dogs that live longer than the normal lifespan for golden retrievers that we always quote of about 10 to 12 years.”&lt;/p&gt;&lt;p&gt;Another recent study already is hinting that at least part of the longevity difference may be linked to variants in a gene encoding an epidermal growth factor receptor. Led by Robert Rebhun, DVM, PhD, chair of medical oncology at the University of California Davis School of Veterinary Medicine, the researchers discovered that a variant in a noncoding region of the &lt;i&gt;ERBB4&lt;/i&gt; gene (also known as &lt;i&gt;HER4&lt;/i&gt;) grants golden retrievers an extra 2 years of life on average.&lt;span&gt;&lt;sup&gt;2&lt;/sup&gt;&lt;/span&gt; Interestingly, &lt;i&gt;ERBB4&lt;/i&gt; appears to have a “good variant” that is associated with longer lifespans and a “bad variant” that is associated with shorter lifespans.&lt;/p&gt;&lt;p&gt;Because longevity in the breed is highly influenced by cancer, the genetic variants are almost certainly associated with cancer as well, says coauthor Michael Kent, DVM, MS, a professor of radiation oncology at the veterinary school.

A breakdown of cases included 46,060 from Shenzhen, 67,472 from Zhengzhou, 25,667 from Shijiazhuang, and 24,649 from Jinan. These collected cases were evaluated using the AICyte system, and the data collected were statistically compared with the original interpretative results.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>In 98.80% of all artificial intelligence cases that were designated as not needing further review, the corresponding original diagnosis was also determined to be negative. For any cases that were designated atypical squamous cells, cannot exclude high-grade squamous intraepithelial lesion or higher, the sensitivity and negative predictive value were 90.77% and 98.80%, respectively. The sensitivity and negative predictive value were greater in cases designated as low-grade squamous intraepithelial lesion or higher at 98.92% and 99.94%, respectively. Of the 49 low-grade squamous intraepithelial lesion or higher that were designed by AICyte as not needing further review, the cytohistologic correlation revealed eight cases of cervical intraepithelial neoplasia 1 and 18 negative cases; and the remaining cases were without histologic follow-up. In practice, AICyte used at a 50% negative cutoff value could reduce the anticipated workload if a protocol were implemented to label cases that qualified within the negative cutoff value as not needing further review, thereby finalizing the case as negative for intraepithelial lesions and malignancy.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>For pathologic practices that do not have cytotechnologists or in which the workflow is sought to be optimized, the artificial intelligence system AICyte alone to be an independent screening tool by using a 50% negative cutoff value, which is a potential assistive method for cervical cancer screening.</p>\u0000 </section>\u0000 </div>","PeriodicalId":9410,"journal":{"name":"Cancer Cytopathology","volume":"132 11","pages":"723-730"},"PeriodicalIF":3.2,"publicationDate":"2024-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cncy.22896","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141999429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
