Publication Quality Following Short Summer Cancer Research Internships.

Publications of research conducted during short-term research education training programs serve as an outcome measure for students' successes and a program's value. We compared the impact of cancer publications from research conducted during a short-term cancer research education training program, to publications by program participants in the years following completion of the training program and earning an academic or professional degree. Bibliometrics and altmetrics from NIH, ResearchGate, Google Scholar and Scopus® that measure publication impact were collected on cancer publications by student interns in the CaRES (Cancer Research Experiences for Students) R25 program from 1999 to 2017; and on cancer publications in subsequent years by program alumni (students who completed CaRES). Publication characteristics and impact measures were described and compared. Of 558 publications, 206 (37%) were related to CaRES internship projects and 352 (63%) related to any cancer research in which program alumni engaged following their internships. CaRES project publications were cited more frequently and held a higher research interest score than later cancer publications by CaRES alumni but appeared in journals having lower impact factors (p < 0.05). A higher proportion of alumni were first authors of their publications as compared to first authorship by interns (p = 0.02). Research conducted during short-term cancer research programs can be scientifically meaningful and of comparable quality to publications by program alumni who engage in cancer research careers.

Mediating Effects of Frailty Indicators on the Risk of Sepsis After Cancer.

BACKGROUND: Cancer survivors are at increased risk of sepsis, possibly attributed to weakened physiologic conditions. The aims of this study were to examine the mediation effect of indicators of frailty on the association between cancer survivorship and sepsis incidence and whether these differences varied by race. METHODS: We performed a prospective analysis using data from the REasons for Geographic and Racial Differences in Stroke cohort from years 2003 to 2012. We categorized frailty as the presence of ≥2 frailty components (weakness, exhaustion, and low physical activity). We categorized participants as "cancer survivors" or "no cancer history" derived from self-reported responses of being diagnosed with any cancer. We examined the mediation effect of frailty on the association between cancer survivorship and sepsis incidence using Cox regression. We repeated analysis stratified by race. RESULTS: Among 28 062 eligible participants, 2773 (9.88%) were cancer survivors and 25 289 (90.03%) were no cancer history participants. Among a total 1315 sepsis cases, cancer survivors were more likely to develop sepsis (12.66% vs 3.81%, P < .01) when compared to participants with no cancer history (hazard ratios: 2.62, 95% confidence interval: 2.31-2.98, P < .01). The mediation effects of frailty on the log-hazard scale were very small: weakness (0.57%), exhaustion (0.31%), low physical activity (0.20%), frailty (0.75%), and total number of frailty indicators (0.69%). Similar results were observed when stratified by race. CONCLUSION: Cancer survivors had more than a 2-fold increased risk of sepsis, and indicators of frailty contributed to less than 1% of this disparity.

A Prospective Study of Community Mediators on the Risk of Sepsis After Cancer.

BACKGROUND: Few studies have examined whether community factors mediate the relationship between patients surviving cancer and future development of sepsis. We determined the influence of community characteristics upon risk of sepsis after cancer, and whether there are differences by race. METHODS: We performed a prospective analysis using data from the REasons for Geographic and Racial Differences in Stroke cohort years 2003 to 2012 complemented with county-level community characteristics from the American Community Survey and County Health Rankings. We categorized those with a self-reported prior cancer diagnosis as "cancer survivors" and those without a history of cancer as "no cancer history." We defined sepsis as hospitalization for a serious infection with ≥2 systemic inflammatory response syndrome criteria. We examined the mediation effect of community characteristics on the association between cancer survivorship and sepsis incidence using Cox proportional hazards models adjusted for age, sex, race, and total number of comorbidities. We repeated analysis stratified by race. RESULTS: There were 28 840 eligible participants, of which 2860 (9.92%) were cancer survivors, and 25 289 (90.08%) were no cancer history participants. The only observed community-level mediation effects were from income (% mediated 0.07%; natural indirect effect [NIE] on hazard scale] = 1.001, 95% confidence interval [95% CI]: 1.000-1.005) and prevalence of adult smoking (% mediated = 0.21%; NIE = 1.002, 95% CI: 1.000-1.004). We observed similar effects when stratified by race. CONCLUSION: Cancer survivors are at increased risk of sepsis; however, this association is weakly mediated by community poverty and smoking prevalence.

Twenty-five-Year Follow-up of Short-term Cancer Research Trainees at the University of Alabama at Birmingham: a Brief Report.

Long-term follow-up is needed to evaluate the impact of short-term cancer research programs on the career trajectories of medical and graduate students. Participation in these programs may be crucial in fostering the next generation of cancer research scientists. This report presents the career outcomes and research productivity of 77 medical and public health students with 25 years of tracking data following their participation in a summer cancer research training program at the University of Alabama at Birmingham (UAB) in 1990-1998. Of 64 summer trainees with contact information, complete survey responses were received from 55 (86.0%) individuals. Over half reported clinical care of cancer patients and 18.2% stated that they were engaged in cancer research. Literature searches confirmed that 23.4% (18/77) of trainees have published cancer research papers. Future studies should explore the optimal timing of short-term post-baccalaureate academic cancer training experiences to identify participant characteristics and institutional factors that influence career choices and determine research productivity.

Automated Literature Searches for Longitudinal Tracking of Cancer Research Training Program Graduates.

A key outcome measure of cancer research training programs is the number of cancer-related peer-reviewed publications after training. Because program graduates do not routinely report their publications, staff must periodically conduct electronic literature searches on each graduate. The purpose of this study is to compare findings of an innovative computer-based automated search program versus repeated manual literature searches to identify post-training peer-reviewed publications. In late 2014, manual searches for publications by former R25 students identified 232 cancer-related articles published by 112 of 543 program graduates. In 2016, a research assistant was instructed in performing Scopus literature searches for comparison with individual PubMed searches on our 543 program graduates. Through 2014, Scopus found 304 cancer publications, 220 of that had been retrieved manually plus an additional 84 papers. However, Scopus missed 12 publications found manually. Together, both methods found 316 publications. The automated method found 96.2 % of the 316 publications while individual searches found only 73.4 %. An automated search method such as using the Scopus database is a key tool for conducting comprehensive literature searches, but it must be supplemented with periodic manual searches to find the initial publications of program graduates. A time-saving feature of Scopus is the periodic automatic alerts of new publications. Although a training period is needed and initial costs can be high, an automated search method is worthwhile due to its high sensitivity and efficiency in the long term.

Inferior outcomes for black children with high risk acute lymphoblastic leukemia and the impact of socioeconomic variables.

BACKGROUND: While significant improvements have been made for children with acute lymphoblastic leukemia (ALL) in the United States over the past 20 years, black patients continue to have inferior outcomes. The full impact of socioeconomic variables on outcomes in this minority population is not entirely understood. PROCEDURE: Disease characteristics, demographic, and socioeconomic status (SES) variables were collected on black (n = 44) and white (n = 178) patients diagnosed at the University of Alabama at Birmingham. Cox proportional hazard regression was used to evaluate the influence of SES and insurance status on survival. RESULTS: As a cohort, 5-year overall survival (OS) was 87% (82-91%), with a median follow-up of 99 months. In univariable analysis, black race was not significantly associated with a higher risk of death or relapse and death. White and black patients with standard-risk leukemia had excellent outcomes, with 97% (91-99%) and 96% (75-99%) 5-year OS, respectively. In contrast, for high-risk disease, white patients had a statistically significant improved 5-year OS rates compared with black patients (79% [68-87%] vs. 52% [28-72%]). Black children were more likely to have public insurance, and, in multivariable analysis, this was associated with a trend toward an improved outcome. Black patients also had poorer census tract-level SES parameters, but these variables were not associated with survival. CONCLUSION: Our study demonstrates significantly inferior outcomes for black children with high-risk leukemia. These outcome disparities were not related to SES variables, including poverty or private insurance coverage, suggesting the involvement of other factors and highlighting the need for a prospective investigative analysis.

Disparities in Cancer Survivorship Indicators in the Deep South Based on BRFSS Data: Recommendations for Survivorship Care Plans.

OBJECTIVES: The purpose of this investigation was to describe cancer survivorship based on the Behavioral Risk Factor Surveillance System (BRFSS) cancer survivorship modules in Alabama, Georgia, and Mississippi, conducted in 2012 and 2014, and to investigate disparities across the US Deep South region. METHODS: The optional BRFSS cancer survivorship module was introduced in 2009. Data from Alabama (2012), Georgia (2012), and Mississippi (2014) were assessed. Demographic factors were analyzed through weighted regression for risk of receiving cancer treatment summary information and follow-up care. RESULTS: Excluding nonmelanoma skin cancer cases, a total of 1105 adults in the Alabama 2012 survey, 571 adults in the Georgia 2012 survey, and 442 adults in the 2014 Mississippi survey reported ever having cancer and were available for analysis. Among Alabamians, those with a higher level of education (odds ratio [OR] 1.4, 95% confidence interval [CI] 1.1-1.7) and higher income (OR 1.3, 95% CI 1.1-1.6) were more likely to receive a written summary of their cancer treatments. Adults older than age 65 were only half as likely to receive a written summary of cancer treatments compared with adults 65 years or younger (OR 0.5, 95% CI 0.3-0.8). We found no significant differences in receipt of treatment summary by race or sex. Among those who reported receiving instructions from a doctor for follow-up care, these survivors tended to have a higher level of education, higher income, and were younger (younger than 65 years). Receipt of written or printed follow-up care was positively associated with higher income (OR 1.4, 95% CI 1.1-1.8) and inversely associated with age older than 65 years (OR 0.9, 95% CI 0.1-0.6) in Georgia. CONCLUSIONS: Addressing the gap identified between survivorship care plan development by the health team and the delivery of it to survivors is important given the evidence of disparities in the receipt of survivorship care plans across survivor age and socioeconomic status in the Deep South.

The National Cancer Institute R25 Cancer Education Grants Program: A Workshop Report.

Through the R25 Cancer Education Grants Program (CEGP), the National Cancer Institute (NCI) has been supporting the broad educational needs of the cancer research and cancer healthcare communities since 1974. NCI sponsored a workshop on September 13, 2016 in Bethesda, Maryland, with the objectives of sharing best practices in cancer education, communicating R25 CEGP programmatic information, and gathering ideas to strengthen the R25 CEGP to better meet the emerging needs in cancer education in the face of a rapidly changing landscape in cancer research and cancer care. With 53 leaders in cancer education in attendance, the workshop featured an overview of the R25 CEGP by NCI Program Staff, a showcase of several types of CEGP programs by current R25 grantees, and in-depth discussions on a broad range of questions critical for the continued success of the R25 CEGP. The workshop afforded an opportunity, for the first time, for cancer researchers and clinicians conducting different forms of cancer education activities to gather in one place as leaders of a community of increasing importance. The discussion resulted in a set of suggestions that will benefit the R25 CEGP and cancer education in general. There was a general consensus among the participants that bringing the cancer education community together is a significant achievement of the workshop that will have a long-lasting impact on cancer education.

Racial disparities in individual breast cancer outcomes by hormone-receptor subtype, area-level socio-economic status and healthcare resources.

The aim of the study is to determine the influence of area-level socio-economic status and healthcare access in addition to tumor hormone-receptor subtype on individual breast cancer stage, treatment, and mortality among Non-Hispanic (NH)-Black, NH-White, and Hispanic US adults. Analysis was based on 456,217 breast cancer patients in the SEER database from 2000 to 2010. Multilevel and multivariable-adjusted logistic and Cox proportional hazards regression analysis was conducted to account for clustering by SEER registry of diagnosis. NH-Black women had greater area-level access to healthcare resources compared with women of other races. For instance, the average numbers of oncology hospitals per million population in counties with NH-Black, NH-White, and Hispanic women were 8.1, 7.7, and 5.0 respectively; average numbers of medical doctors per million in counties with NH-Black, NH-White, and Hispanic women were 100.7, 854.0, and 866.3 respectively; and average number of Ob/Gyn in counties with NH-Black, NH-White, and Hispanic women was 155.6, 127.4, and 127.3, respectively (all p values <0.001). Regardless, NH-Black women (HR 1.39, 95 % CI 1.36-1.43) and Hispanic women (HR 1.05, 95 % CI 1.03-1.08) had significantly higher breast cancer mortality compared with NH-White women even after adjusting for hormone-receptor subtype, area-level socio-economic status, and area-level healthcare access. In addition, lower county-level socio-economic status and healthcare access measures were significantly and independently associated with stage at presentation, surgery, and radiation treatment as well as mortality after adjusting for age, race/ethnicity, and HR subtype. Although breast cancer HR subtype is a strong, important, and consistent predictor of breast cancer outcomes, we still observed significant and independent influences of area-level SES and HCA on breast cancer outcomes that deserve further study and may be critical to eliminating breast cancer outcome disparities.

Availability of Healthcare Resources and Colorectal Cancer Outcomes Among Non-Hispanic White and Non-Hispanic Black Adults.

This study aims to examine if access to healthcare, measured through the availability of medical resources at the neighborhood level, influences colorectal cancer (CRC) stage, treatment and survival using the Surveillance Epidemiology and Ends Result (SEER) dataset (November 2012), linked with the 2004 Area Resource File. A cross-sectional study was conducted to determine the association between availability of healthcare resources and CRC outcomes among non-Hispanic Black (n = 9162) and non-Hispanic White patients (n = 97,264). CRC patients were identified using the SEER*Stat program, and individual socio-demographic, clinical, and county-level healthcare access variables were obtained for each patient. Among NH-W patients, residence in counties with lower number of oncology hospitals was associated with increased odds of late stage diagnosis (OR 1.09, 95 % CI 1.04-1.14), reduced odds of receiving surgery (OR 0.83, 95 % CI 0.74-0.92) and higher hazard rates (HR 1.09, 95 % CI 1.06-1.12). There were no significant associations among NH-B patients. Increased availability of healthcare resources improves CRC outcomes among NH-W patients. However, future studies are required to better understand healthcare utilization patterns in NH-B neighborhoods, and identify other important dimensions of healthcare access such as affordability, acceptability and accommodation.

An Evaluation Methodology for Longitudinal Studies of Short-Term Cancer Research Training Programs.

The need to familiarize medical students and graduate health professional students with research training opportunities that cultivate the appeal of research careers is vital to the future of research. Comprehensive evaluation of a cancer research training program can be achieved through longitudinal tracking of program alumni to assess the program's impact on each participant's career path and professional achievements. With advances in technology and smarter means of communication, effective ways to track alumni have changed. In order to collect data on the career outcomes and achievements of nearly 500 short-term cancer research training program alumni from 1999-2013, we sought to contact each alumnus to request completion of a survey instrument online, or by means of a telephone interview. The effectiveness of each contact method that we used was quantified according to ease of use and time required. The most reliable source of contact information for tracking alumni from the early years of the program was previous tracking results, and for alumni from the later years, the most important source of contact information was university alumni records that provided email addresses and telephone numbers. Personal contacts with former preceptors were sometimes helpful, as were generic search engines and people search engines. Social networking was of little value for most searches. Using information from two or more sources in combination was most effective in tracking alumni. These results provide insights and tools for other research training programs that wish to track their alumni for long-term program evaluation.

Career Outcomes of Graduates of R25E Short-Term Cancer Research Training Programs.

The efficacy of short-term cancer research educational programs in meeting its immediate goals and long-term cancer research career objectives has not been well studied. The purpose of this report is to describe the immediate impact on, and the long-term career outcomes of, 499 medical students and graduate students who completed the Cancer Research Experiences for Students (CaRES) program at the University of Alabama at Birmingham (UAB) from 1999 to 2013. In summer 2014, all 499 program alumni were located and 96.4 % (481 of 499) agreed to complete a longitudinal tracking survey. About 23 % of CaRES alumni (110 of 499) have published at least one cancer-related paper. Overall 238 cancer-related papers have been published by CaRES alumni, one third of this number being first-authored publications. Nearly 15 % (71 of 481 respondents) reported that their current professional activities include cancer research, primarily clinical research and outcomes research. Of these 71 individuals, 27 (38 %) have completed their training and 44 (62 %) remain in training. Of all respondents, 58 % reported that they administered care to cancer patients and 30 % reported other cancer-related professional responsibilities such as working with a health department or community group on cancer control activities. Of the 410 respondents not currently engaged in cancer research, 118 (29 %) stated intentions to conduct cancer research in the next few years. Nearly all respondents (99.6 %) recommended CaRES to today's students. Challenging short-term educational cancer research programs for medical students and graduate health professional students can help them refine and solidify their career plans, with many program alumni choosing cancer research careers.

Predictors of colorectal cancer surveillance among survivors of childhood cancer treated with radiation: a report from the Childhood Cancer Survivor Study.

BACKGROUND: Childhood cancer survivors treated with radiotherapy to a field including the colon or rectum have an elevated risk of developing radiation-induced colorectal cancer (CRC). The Children's Oncology Group recommends colonoscopy every 5 years beginning at age 35 years for at-risk survivors. METHODS: Analyses included 702 five-year survivors (Childhood Cancer Survivor Study) aged ≥36 years who received ≥30 gray of abdominal, pelvic, or spinal radiotherapy. Multivariate generalized linear models were used to calculate relative risks (RR) with 95% confidence intervals (95% CI) for adherence to the Children's Oncology Group's CRC surveillance recommendations. RESULTS: With a median age of 43 years (range, 36-58 years), 29.5% of the survivors (207 of 702 survivors) met surveillance recommendations. In multivariate analyses, age ≥50 years versus age 36 to 49 years (RR, 2.6; 95% CI, 2.0-3.4), reporting a routine cancer follow-up visit within 1 year before the study (RR, 1.5; 95% CI, 1.0-2.2), reporting ≥10 physician visits within the past year versus 0 to 9 visits (RR, 1.4; 95% CI, 1.1-1.7), and discussing future cancer risk with a physician at the time of the most recent follow-up visit (RR, 1.4; 95% CI, 1.1-1.7) were found to be associated with adherence to CRC surveillance recommendations. CONCLUSIONS: Greater than 70% of survivors at an increased risk of CRC were not screened as recommended. Regular physician contact and discussion of screening were associated with a 60% increase in CRC surveillance. Educational interventions targeted at survivors and their primary care physicians are needed to heighten knowledge of CRC risk after radiotherapy and the importance of appropriate surveillance.

Correlates of self-reported dietary cruciferous vegetable intake and urinary isothiocyanate from two cohorts in China.

OBJECTIVE: To assess correlations between cruciferous vegetable intake and urinary isothiocyanate (ITC) level, in addition to glutathione S-transferase (GST) genotypes and other individual factors. DESIGN: The study included cohort participants whose urinary ITC levels had been previously ascertained. Urinary ITC was assessed using HPLC. Usual dietary intake of cruciferous vegetables was assessed using a validated FFQ and total dietary ITC intake was calculated. Recent cruciferous vegetable intake was determined. GST genotypes were assessed using duplex real-time quantitative PCR assays. Spearman correlations were calculated between the covariates and urinary ITC levels and linear regression analyses were used to calculate the mean urinary ITC excretion according to GST genotype. SETTING: Urban city in China. SUBJECTS: The study included 3589 women and 1015 men from the Shanghai Women's and Men's Health Studies. RESULTS: Median urinary ITC level was 1.61 nmol/mg creatinine. Self-reported usual cruciferous vegetable intake was weakly correlated with urinary ITC level (r s=0.1149; P<0.0001), while self-reported recent intake was more strongly correlated with urinary ITC (r s=0.2591; P<0.0001). Overall, the GST genotypes were not associated with urinary ITC level, but significant differences according to genotype were observed among current smokers and participants who provided an afternoon urine sample. Other factors, including previous gastrectomy or gastritis, were also related to urinary ITC level. CONCLUSIONS: The study suggests that urinary secretion of ITC may provide additional information on cruciferous vegetable intake and that GST genotypes are related to urinary ITC level only in some subgroups.

Sustainability in a state comprehensive cancer control coalition: lessons learned.

The Alabama Comprehensive Cancer Control Coalition (ACCCC) has developed an integrated and coordinated approach to reducing cancer incidence, morbidity, and mortality, and to improving the quality of life for cancer survivors, their families, and their caregivers. The ACCCC is currently in a maintenance phase and a formal plan for sustainability of the coalition was needed to keep the members engaged and productive. A training session in coalition sustainability conducted in 2013 identified the following elements as essential to success: (1) increased marketing of the coalition by simplifying its mission; (2) improved networking including flexibility in coalition meeting location and attendance; (3) increased membership satisfaction through transformational leadership; (4) revision of the working structure of committees and improved accountability; and (5) enhancement of partner satisfaction with coalition activities designed to recruit and retain new partners. A self-administered membership satisfaction survey was given to assess coalition mission, meeting logistics, organization, capacity building, and coalition goals. Results indicated that the subcategories of communication, mission, and meeting logistics were rated satisfied to very satisfied on a five-point scale. Although the ACCCC had clearly written goals, improvement could be made in leadership participation and new member orientation could be improved. Most members rated their parent organization as highly involved with the ACCCC and many offered suggestions on capacity building. Results of the sustainability training have clarified the ACCCC's plans to ensure coalition viability and improve strategies to inform stakeholders of the benefits of participation in the coalition.

Fruit and vegetable intake and the risk of colorectal cancer: results from the Shanghai Men's Health Study.

PURPOSE: The observed associations of fruit and vegetable consumption with the risk of colorectal cancer have been inconsistent. Therefore, we aimed to evaluate the association of fruit and vegetable consumption with the risk of colorectal cancer among Chinese men. METHODS: 61,274 male participants aged 40-74 years were included. A validated food frequency questionnaire was administered to collect information on usual dietary intake, including 8 fruits and 38 vegetables commonly consumed by residents of Shanghai. Follow-up for diagnoses of colon or rectal cancer was available through 31 December 2010. Dietary intakes were analyzed both as categorical and continuous variables. Multivariable-adjusted hazard ratios (HRs) and 95 % confidence intervals (95 % CIs) were calculated for colorectal, colon, and rectal cancers using Cox proportional hazards models. RESULTS: After 390,688 person-years of follow-up, 398 cases of colorectal cancer (236 colon and 162 rectal) were observed in the cohort. Fruit consumption was inversely associated with the risk of colorectal cancer (fifth vs. first quintile HR 0.67; 95 % CI 0.48, 0.95; p trend = 0.03), whereas vegetable intake was not significantly associated with risk. The associations for subgroups of fruits and legumes, but not other vegetable categories, were generally inversely associated with the risk of colon and rectal cancers. CONCLUSIONS: Fruit intake was generally inversely associated with the risk of colorectal cancer, whereas vegetable consumption was largely unrelated to risk among middle-aged and older Chinese men.

An achievement of professional, public, and patient education: the design and evaluation of a comprehensive cancer control plan for Alabama.

This Alabama statewide cancer control plan for 2011-2015 seeks to build on the successes of two previous 5-year plans while developing new objectives that address cancer disparities and cancer prevention over the entire lifespan. The approach to defining objectives for this Plan was systematic and sought input from all members of the Alabama Comprehensive Cancer Control Coalition (ACCCC). The Plan that was fashioned is based on input from academic medical centers, private physicians, government agencies, regulatory agencies, health societies, private citizens, and cancer survivors, all of whom are active Coalition members who exchange information, opinions, and knowledge from their respective points of view. The Plan could not have taken shape without the full input of health professionals, statisticians, graduate students, former patients, and concerned citizens; it is truly an example of the synergy of professional, public, and patient education.

Auditory complications in childhood cancer survivors: a report from the childhood cancer survivor study.

BACKGROUND: Studies have found associations between cancer therapies and auditory complications, but data are limited on long-term outcomes and risks associated with multiple exposures. PROCEDURE: The Childhood Cancer Survivor Study is a retrospective cohort investigating health outcomes of long-term survivors (5+ years) diagnosed and treated between 1970 and 1986 compared to a randomly selected sibling cohort. Questionnaires were completed by 14,358 survivors of childhood cancer and 4,023 sibling controls. Analysis determined the first occurrence of four auditory conditions in two time periods: diagnosis to 5 years post-diagnosis, and ≥ 5 years post-diagnosis. Multivariable analyses determined the relative risks (RR) and 95% confidence interval (CI) of auditory conditions by treatment exposure. RESULTS: Five or more years from cancer diagnosis, survivors were at increased risk of problems hearing sounds (RR = 2.3; 95% CI: 1.8-2.8), tinnitus (RR = 1.7; 95% CI: 1.4-2.1), hearing loss requiring an aid (RR = 4.4; 95% CI: 2.8-6.9), and hearing loss in 1 or both ears not corrected by a hearing aid (RR = 5.2; 95% CI: 2.8-9.5), when compared to siblings. Temporal lobe and posterior fossa radiation was associated with these outcomes in a dose-dependent fashion. Exposure to platinum compounds was associated with an increased risk of problems hearing sounds (RR = 2.1; 95% CI: 1.3-3.2), tinnitus (RR = 2.8; 95% CI: 1.9-4.2), and hearing loss requiring an aid (RR = 4.1; 95% CI: 2.5-6.7). CONCLUSIONS: Childhood cancer survivors are at risk of developing auditory complications. Radiation and platinum compounds are determinants of this risk. Follow-up is needed to evaluate the impact of auditory conditions on quality of life.

Approaches for longitudinally tracking graduates of NCI-funded short-term cancer research training programs.

Short-term cancer research programs for health professions students typically state goals of encouraging and fostering interest in pursuing cancer research-based careers. Evaluating career choices and professional achievements of these trainees has been problematic. Well-designed program evaluation is a key element in determining successful training experiences, and program-specific outcome measures are typically used to assess the effectiveness of each short-term cancer research experience. We describe evaluation approaches for longitudinal tracking of participants of our National Cancer Institute-sponsored Cancer Research Experiences for Students program at the University of Alabama at Birmingham, emphasizing those approaches that demonstrated greatest effectiveness. We also evaluate the various methods we used in terms of cost, efficiency, and effectiveness. Recommendations are provided to assist comparable training programs facing the challenges of longitudinal tracking and program evaluation.

Ocular late effects in childhood and adolescent cancer survivors: a report from the childhood cancer survivor study.

INTRODUCTION: Approximately 80% of children currently survive 5 years following diagnosis of their cancer. Studies based on limited data have implicated certain cancer therapies in the development of ocular sequelae in these survivors. PROCEDURE: The Childhood Cancer Survivor Study (CCSS) is a retrospective cohort study investigating health outcomes of 5+ year survivors diagnosed and treated between 1970 and 1986 compared to a sibling cohort. The baseline questionnaire included questions about the first occurrence of six ocular conditions. Relative risks (RR) and 95% confidence intervals (CI) were calculated from responses of 14,362 survivors and 3,901 siblings. RESULTS: Five or more years from the diagnosis, survivors were at increased risk of cataracts (RR: 10.8; 95% CI: 6.2-18.9), glaucoma (RR: 2.5; 95% CI: 1.1-5.7), legal blindness (RR: 2.6; 95% CI: 1.7-4.0), double vision (RR: 4.1; 95% CI: 2.7-6.1), and dry eyes (RR: 1.9; 95% CI: 1.6-2.4), when compared to siblings. Dose of radiation to the eye was significantly associated with risk of cataracts, legal blindness, double vision, and dry eyes, in a dose-dependent manner. Risk of cataracts were also associated with radiation 3,000+ cGy to the posterior fossa (RR: 8.4; 95% CI: 5.0-14.3), temporal lobe (RR: 9.4; 95% CI: 5.6-15.6), and exposure to prednisone (RR: 2.3; 95% CI: 1.6-3.4). CONCLUSIONS: Childhood cancer survivors are at risk of developing late occurring ocular complications, with exposure to glucocorticoids and cranial radiation being important determinants of increased risk. Long-term follow-up is needed to evaluate potential progression of ocular deficits and impact on quality of life.
