Background Methods Results Conclusions The Oncotype DX Genomic Prostate Score (ODX‐GPS) is a gene expression assay that predicts disease aggressiveness. The objective of this study was to identify sociodemographic and regional factors associated with ODX‐GPS uptake.Data from Surveillance Epidemiology and End Results registries on men with localized prostate cancer with a Gleason score of 3 + 3 or 3 + 4, PSA ≤20 ng/mL, and stage T1c to T2c disease from 2013 through 2017 were linked with ODX‐GPS data. Census‐tract level neighborhood socioeconomic status (nSES) quintiles were constructed using a composite socioeconomic score. Multivariable logistic regression was used to estimate the associations of ODX‐GPS uptake with age at diagnosis, race and ethnicity, nSES, geographic region, insurance type, and marital status, accounting for National Comprehensive Cancer Network risk group, year of diagnosis, and clustering by census tract.Among 111,434 eligible men, 5.5% had ODX‐GPS test uptake. Of these, 78.3% were non‐Hispanic White, 9.6% were Black, 6.7% were Hispanic, and 3.6% were Asian American. Black men had the lowest odds of ODX‐GPS uptake (odds ratio, 0.70; 95% confidence interval [CI], 0.63–0.76). Those in the highest versus lowest quintile of nSES were 1.64 times more likely (95% CI, 1.38–2.94) to have ODX‐GPS uptake. The odds of ODX‐GPS uptake were statistically significantly higher among men residing in the Northeast, West, and Midwest compared to the South.Disparities in ODX‐GPS uptake by race, ethnicity, nSES, and geographical region were identified. Concerted efforts should be made to ensure that this clinical test is equitably available. [ABSTRACT FROM AUTHOR]

Background: Precision medicine has become a mainstay of cancer care in recent years. The National Cancer Institute (NCI) Surveillance, Epidemiology, and End Results (SEER) Program has been an authoritative source of cancer statistics and data since 1973. However, tumor genomic information has not been adequately captured in the cancer surveillance data, which impedes population-based research on molecular subtypes. To address this, the SEER Program has developed and implemented a centralized process to link SEER registries' tumor cases with genomic test results that are provided by molecular laboratories to the registries., Methods: Data linkages were carried out following operating procedures for centralized linkages established by the SEER Program. The linkages used Match*Pro, a probabilistic linkage software, and were facilitated by the registries' trusted third party (an honest broker). The SEER registries provide to NCI limited datasets that undergo preliminary evaluation prior to their release to the research community., Results: Recently conducted genomic linkages included OncotypeDX Breast Recurrence Score, OncotypeDX Breast Ductal Carcinoma in Situ, OncotypeDX Genomic Prostate Score, Decipher Prostate Genomic Classifier, DecisionDX Uveal Melanoma, DecisionDX Preferentially Expressed Antigen in Melanoma, DecisionDX Melanoma, and germline tests results in Georgia and California SEER registries., Conclusions: The linkages of cancer cases from SEER registries with genomic test results obtained from molecular laboratories offer an effective approach for data collection in cancer surveillance. By providing de-identified data to the research community, the NCI's SEER Program enables scientists to investigate numerous research inquiries., (© The Author(s) 2024.

Background: Immunosuppressed individuals have elevated risk of virus-related cancers. Identifying cancers with elevated risk in people with HIV (PWH) and solid organ transplant recipients (SOTRs), two immunosuppressed populations, may help identify novel etiologic relationships with infectious agents., Methods: We utilized two linkages of population-based cancer registries with HIV and transplant registries in the United States. Cancer entities were systematically classified based on site and histology codes. Standardized incidence ratios (SIRs) were used to compare risk in PWH and SOTRs with the general population. For selected cancer entities, incidence rate ratios (IRRs) were calculated for indicators of immunosuppression within each population., Findings: We identified 38,047 cancer cases in SOTRs and 53,592 in PWH, yielding overall SIRs of 1.66 (95%CI = 1.65-1.68) and 1.49 (95%CI = 1.47-1.50), respectively. Forty-three cancer entities met selection criteria, including conjunctival squamous cell carcinoma (SCC) (PWH SIR = 7.1, 95%CI = 5.5-9.2; SOTRs SIR = 9.4; 95%CI = 6.8-12.6). Sebaceous adenocarcinoma was elevated in SOTRs (SIR = 16.2; 95%CI = 14.0-18.6) and, among SOTRs, associated with greater risk in lung/heart transplant recipients compared to recipients of other organs (IRR = 2.3; 95%CI = 1.7-3.2). Salivary gland tumors, malignant fibrous histiocytoma (MFH), and intrahepatic cholangiocarcinoma showed elevated risk in SOTRs (SIR = 3.9; SIR = 4.7; and SIR = 3.2, respectively) but not in PWH. However, risks for these cancers were elevated following an AIDS diagnosis among PWH (IRR = 2.4; IRR = 4.3; and IRR = 2.0, respectively)., Interpretation: Elevated SIRs among SOTRs and PWH, and associations with immunosuppression within these populations, suggest novel infectious causes for several cancers including conjunctival SCC, sebaceous adenocarcinoma, salivary gland tumors, MFH, and intrahepatic cholangiocarcinoma., (Published by Oxford University Press 2024.)
