Most countries, therefore, do not have enough cases to provide robust information on epidemiology, treatment, and late effects, especially for rarer types of cancer. Thus, only through a concerted effort to share data internationally will we be able to answer research questions that could not otherwise be answered. With this goal in mind, the U.S. National Cancer Institute and the French National Cancer Institute co-sponsored the Paris Conference for an International Childhood Cancer Data Partnership in November 2023. This meeting convened more than 200 participants from 17 countries to address complex challenges in pediatric cancer research and data sharing. This Commentary delves into some key topics discussed during the Paris Conference and describes pilots that will help move this international effort forward. Main topics presented include: 1) the wide variation in interpreting the European Union's General Data Protection Regulation among Member States; 2) obstacles with transferring personal health data outside of the European Union; 3) standardization and harmonization, including common data models; and 4) novel approaches to data sharing such as federated querying and federated learning. We finally provide a brief description of three ongoing pilot projects. The International Childhood Cancer Data Partnership is the first step in developing a process to better support pediatric cancer research internationally through combining data from multiple countries.","PeriodicalId":501635,"journal":{"name":"Journal of the National Cancer Institute","volume":"47 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142968218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

METHODS Five-year survivors of primary childhood cancers diagnosed between 1970-1999 in the Childhood Cancer Survivor Study with a subsequent CNS SMN were identified. Cumulative incidence rates and standardized incidence ratios (SIR) were compared among survivors diagnosed between 1970-1979 (N = 6223), 1980-1989 (N = 9680), and 1990–1999 (N = 8999). Multivariable models assessed risk factors for CNS SMN. RESULTS 157 CNS SMNs (1970s, 52; 1980s, 63; 1990s, 42) were identified, excluding meningiomas, which were most often malignant gliomas. The proportion of survivors receiving any cranial radiotherapy (CRT) exposure was reduced over time (1970s 77.0%, 1980s 54.3%, 1990s 33.9%), while the proportion receiving >35Gy CRT showed a smaller reduction (11.4%, 10.8%, and 8.5%, respectively). Twenty-year cumulative incidence (95% CI) and SIR (95% CI) for CNS SMN by treatment decade were 0.32% (0.18-0.46%) and 6.6 (5.0–8.7); 0.55% (0.41-0.70%) and 8.3 (6.6-10.4); and 0.43% (0.31-0.55%) and 9.2 (7.0–12.0), respectively, with no statistically significant decreases between eras. Multivariable analyses showed increased risk for CRT dose levels >10Gy and for primary diagnoses of medulloblastoma/PNET (HR 18.7, 9.2-37.9) and astrocytoma (HR 10.1, 5.3-19.5). Three-year cumulative incidence of death after CNS SMN, by treatment decade, were 76%, 74%, and 73%, respectively. CONCLUSION CNS SMN incidence has not decreased despite fewer survivors exposed to CNS-directed radiotherapy. CNS SMNs remain a substantial source of mortality for affected patients.","PeriodicalId":501635,"journal":{"name":"Journal of the National Cancer Institute","volume":"83 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142939660","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted a population-based assessment of these outcomes in a large, diverse sample. Methods Male AYAs diagnosed between January 1, 1995 and December 31, 2015 were identified using the Texas Cancer Registry and linked to live birth certificates and the Texas Birth Defects Registry through December 31, 2016. Cumulative incidence of live birth after diagnosis was estimated. Log binomial regression models were used to estimate prevalence of preterm birth (<37 weeks), low birth weight (<2,500 grams), small for gestational age (<10th percentile), and any birth defect among liveborn offspring of male AYAs compared to age- and race/ethnicity-matched men without cancer. Results We identified 42,896 male AYAs, among whom germ cell cancers (20.0%) were the most common. There were 9,686 live births to 6,833 male AYAs after diagnosis. Cumulative incidence of live birth was 18.0% (95% CI 17.6, 18.4) at ten years after diagnosis. Ten-year cumulative incidence differed by cancer type (p < .01) and was highest for thyroid (27.6%, 95% CI 25.4, 29.9) but lowest for gastrointestinal (9.6%, 95% CI 8.1, 10.6) cancer. Prevalence of preterm birth (8.9 vs. 8.0%, p = .02) and low birth weight (6.0 vs. 5.3%, p = .02) was higher for liveborn offspring of male AYAs compared to men without cancer.

Using All of Us data, we conducted an intersectional analysis of behavioral financial hardship among LGBTQ+ cancer survivors. Methods LGBTQ+ inequities in behavioral financial hardship (ie, cost-related foregone care, delayed care, and medication alterations) and non-cost-related delayed care were estimated using All of Us Data. Multivariable logit models were used to generate predicted probabilities, average marginal effects (AME), and 95% confidence intervals.

Less is known about whether timing matters regarding when depression occurs. To provide evidence for an etiologically relevant exposure period, we examined depression occurring during the time in which precursor lesions develop and progress to invasive carcinoma with risk of developing ovarian cancer. Methods Using data from two prospective cohorts (1992-2015), we divided follow-up into consecutive two-year periods for analytic purposes, referred to as “cancer ascertainment periods.” We estimated associations of depression in the 10 years before each cancer ascertainment period with incident cancer, using Cox proportional hazards models. Next, we estimated associations of depression occurring up to 18 years before each ascertainment period, in two-year increments, with incident cancer. We adjusted for demographic, health, and behavioral factors. All tests of statistical significance were 2-sided, with a p-value threshold of < 0.05. Results Depression occurring in the 10 prior years was associated with 30% greater risk of cancer (hazard ratio (HR)=1.30, 95% confidence interval (CI)=1.15-1.46). Associations were similar in fully adjusted models (HR = 1.27). Depression occurring in the 14 years before ascertainment was associated with elevated risk, although only estimates for depression 0-2, 6-8, and 8-10 years before ascertainment reached statistical significance (HR range, 1.20-1.36). Conclusion Depression occurring up to 14 years before cancer ascertainment was associated with greater cancer risk. This is the time of precursor progression to invasive ovarian carcinoma, suggesting depression may be an ovarian cancer promoting agent.","PeriodicalId":501635,"journal":{"name":"Journal of the National Cancer Institute","volume":"34 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142917407","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research shows differential racial enrollment patterns due to comorbidity-based exclusion criteria (CEC). Our objective was to evaluate contemporary trends in CECs among NCI-sponsored gynecologic cancer clinical trials and protocol adherence to broadened eligibility criteria guidelines as an assessment of equitable enrollment access. Methods The ClinicalTrials.gov registry was queried for NCI-sponsored gynecologic cancer clinical trials (1994-2021). Study characteristics and CECs were abstracted from protocols. Descriptive statistics and temporal trends were calculated using chi-square testing with STATA v17 software. Results Among 279 clinical trials identified, 65% completed enrollment, 53% were Phase II, and 48% focused on ovarian cancer. Pharmaceutical agents (85%) were the primary therapeutic interventions. Several inequitably restrictive exclusion criteria increased over time such as hepatitis infection (17% in 1994-2000 vs 49% in 2015-2021, p < .001) and cardiovascular disease (47% in 1994-2000 vs 66% in 2015-2021, p = .002). A previously rare exclusion, “mental illness/social situations,” dramatically increased from 5% to 51% (p < .001) over three decades.

Estimates based on remote (eg, >10 years before follow-up) and recent (eg, the preceding 10 years before follow-up) alcohol intake, using different cutoffs (eg, 8, 10, 12 years, etc) and mutual adjustment, enabled separating independent effects and investigating time lag of alcohol-CRC association.
