The authors studied frequent loss of heterozygosity (LOH) on chromosome 8p22 and its association with disease progression that occurred later in patients with breast carcinoma.To examine whether allelic losses at 8p22 might correlate with postoperative survival during a 5-year period of prospective follow-up, the authors tested tumors from a cohort of 298 breast carcinoma patients informative for 8p22 markers. The tumors were tested for allelic losses of microsatellite markers D8S136 and D8S1106 located at 8p22, a chromosomal region where genetic alterations are frequent in breast carcinomas.Among the 298 breast carcinoma patients, 154 (52%) lost alleles in tumors. Patients whose tumors had lost an allele at 8p22 had a significantly higher risk of postoperative mortality than those whose tumors retained both alleles at those loci; their 5-year mortality rates were 18% (26 patients died among 154 with losses at 8p22) versus 7% (10 patients died among 144 with retentions at 8p22) (P = 0.017). The 8p22 LOH was a significant independent prognostic factor for postoperative survival in a group of patients with large tumors (2.1 cm) and in a group of patients with estrogen receptor negative tumors in both univariate and multivariate analyses. These data show that 8p22 LOH was a significant prognostic factor for the postoperative survival of certain clinical groups of patients who underwent surgery for breast carcinoma.Allelic loss on chromosome 8p22 can serve as a negative prognostic indicator to guide the postoperative management of patients, especially patients with large tumors (2.1 cm) and those with estrogen receptor negative tumors."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1381418521015667970","@type":"Researcher","foaf:name":[{"@value":"Yoshihito Utada"}]},{"@id":"https://cir.nii.ac.jp/crid/1381418521015667971","@type":"Researcher","foaf:name":[{"@value":"Shunsuke Haga"}]},{"@id":"https://cir.nii.ac.jp/crid/1381418521015667973","@type":"Researcher","foaf:name":[{"@value":"Tetsuro Kajiwara"}]},{"@id":"https://cir.nii.ac.jp/crid/1381418521015667974","@type":"Researcher","foaf:name":[{"@value":"Fujio Kasumi"}]},{"@id":"https://cir.nii.ac.jp/crid/1381418521015667969","@type":"Researcher","foaf:name":[{"@value":"Goi Sakamoto"}]},{"@id":"https://cir.nii.ac.jp/crid/1381418521015667972","@type":"Researcher","foaf:name":[{"@value":"Yusuke Nakamura"}]},{"@id":"https://cir.nii.ac.jp/crid/1381418521015667968","@type":"Researcher","foaf:name":[{"@value":"Mitsuru Emi"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"0008543X"},{"@type":"EISSN","@value":"10970142"}],"prism:publicationName":[{"@value":"Cancer"}],"dc:publisher":[{"@value":"Wiley"}],"prism:publicationDate":"2000-03-15","prism:volume":"88","prism:number":"6","prism:startingPage":"1410","prism:endingPage":"1416"},"reviewed":"false","dcterms:accessRights":"http://purl.org/coar/access_right/c_abf2","dc:rights":["http://doi.wiley.com/10.1002/tdm_license_1.1"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1002%2F(SICI)1097-0142(20000315)88:6%3C1410::AID-CNCR19%3E3.0.CO;2-X"},{"@id":"https://onlinelibrary.wiley.com/doi/full/10.1002/(SICI)1097-0142(20000315)88:6%3C1410::AID-CNCR19%3E3.0.CO;2-X"}],"createdAt":"2004-11-12","modifiedAt":"2021-07-01","foaf:topic":[{"@id":"https://cir.nii.ac.jp/all?q=Adult","dc:title":"Adult"},{"@id":"https://cir.nii.ac.jp/all?q=Genetic%20Markers","dc:title":"Genetic Markers"},{"@id":"https://cir.nii.ac.jp/all?q=Loss%20of%20Heterozygosity","dc:title":"Loss of Heterozygosity"},{"@id":"https://cir.nii.ac.jp/all?q=Breast%20Neoplasms","dc:title":"Breast Neoplasms"},{"@id":"https://cir.nii.ac.jp/all?q=Cohort%20Studies","dc:title":"Cohort Studies"},{"@id":"https://cir.nii.ac.jp/all?q=Risk%20Factors","dc:title":"Risk Factors"},{"@id":"https://cir.nii.ac.jp/all?q=Odds%20Ratio","dc:title":"Odds Ratio"},{"@id":"https://cir.nii.ac.jp/all?q=Humans","dc:title":"Humans"},{"@id":"https://cir.nii.ac.jp/all?q=Prospective%20Studies","dc:title":"Prospective Studies"},{"@id":"https://cir.nii.ac.jp/all?q=Alleles","dc:title":"Alleles"},{"@id":"https://cir.nii.ac.jp/all?q=Aged","dc:title":"Aged"},{"@id":"https://cir.nii.ac.jp/all?q=Proportional%20Hazards%20Models","dc:title":"Proportional Hazards Models"},{"@id":"https://cir.nii.ac.jp/all?q=Aged,%2080%20and%20over","dc:title":"Aged, 80 and over"},{"@id":"https://cir.nii.ac.jp/all?q=Analysis%20of%20Variance","dc:title":"Analysis of Variance"},{"@id":"https://cir.nii.ac.jp/all?q=Carcinoma","dc:title":"Carcinoma"},{"@id":"https://cir.nii.ac.jp/all?q=DNA,%20Neoplasm","dc:title":"DNA, Neoplasm"},{"@id":"https://cir.nii.ac.jp/all?q=Middle%20Aged","dc:title":"Middle Aged"},{"@id":"https://cir.nii.ac.jp/all?q=Prognosis","dc:title":"Prognosis"},{"@id":"https://cir.nii.ac.jp/all?q=Survival%20Rate","dc:title":"Survival Rate"},{"@id":"https://cir.nii.ac.jp/all?q=Treatment%20Outcome","dc:title":"Treatment Outcome"},{"@id":"https://cir.nii.ac.jp/all?q=Receptors,%20Estrogen","dc:title":"Receptors, Estrogen"},{"@id":"https://cir.nii.ac.jp/all?q=Multivariate%20Analysis","dc:title":"Multivariate Analysis"},{"@id":"https://cir.nii.ac.jp/all?q=Disease%20Progression","dc:title":"Disease Progression"},{"@id":"https://cir.nii.ac.jp/all?q=Female","dc:title":"Female"},{"@id":"https://cir.nii.ac.jp/all?q=Chromosomes,%20Human,%20Pair%208","dc:title":"Chromosomes, Human, Pair 8"},{"@id":"https://cir.nii.ac.jp/all?q=Follow-Up%20Studies","dc:title":"Follow-Up Studies"},{"@id":"https://cir.nii.ac.jp/all?q=Microsatellite%20Repeats","dc:title":"Microsatellite Repeats"}],"relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1390001204481212160","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Postoperative Prognosis of Node-Negative Breast Cancers Predicted by Gene-Expression Profiling on a cDNA Microarray of 25,344 Genes"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1002/(sici)1097-0142(20000315)88:6<1410::aid-cncr19>3.0.co;2-x"},{"@type":"OPENAIRE","@value":"doi_dedup___::01439f82a31d11aac55f9bf77ae327f0"},{"@type":"CROSSREF","@value":"10.2325/jbcs.12.166_references_DOI_NTCpfLE8xOyPhcL3eIgYwpc7ghr"}]}
