Organization and Communication: The Womens Environment, Cancer and Radiation Epidemiology (WECARE) Study Jonine Bernstein, Ph.D.
WECARE Study Overview Purpose To examine the interaction of radiation exposure and genetic susceptibility in the etiology of second primary breast cancer. Hypothesis A woman who carries a mutant variant in one of the genes under study will be more susceptible to radiation-induced cancer than a woman who is not a carrier. Design Population-based, case-control study –Cases are women with bilateral breast cancer –Controls are women with unilateral breast cancer (Bernstein, …, Thompson, Br Ca Res 2004)
WECARE Study Design Cases (n=708) Diagnosed since 1/1/1985 with incident breast cancer Diagnosed since 1/1/1986 with contralateral breast cancer One year or longer time lag between primaries Under age 55 at diagnosis of the first primary No other cancer diagnosis Alive
WECARE Study Design Controls (n=1397) With unilateral breast cancer Individually matched 2:1 to cases on: –Registry –Age (5 year) –Diagnosis date of breast cancer (4 year) –Race No other cancer diagnosis Counter-matched on radiotherapy status –2:1 (RRT+: RRT -)
WECARE Study Data Collection Women identified through 5 population- based cancer registries (US and Denmark) Telephone interview using a structured questionnaire During home visits, a blood sample drawn by a study phlebotomist
Medical Treatment Information and Data for Radiation Dosimetry Sources –Treatment and tumor characteristics information collected registry records –Hospital charts –Pathology/surgery reports –Doctor office /mammography records –Radiation oncology files Missing Data –~ 7% patient records inadequate for dosimetry –~ 2% participants have all documentation missing
Contralateral Breast Dose (cGy): Mean and Range among Patients Treated with Breast Irradiation (1488 patients)
Laboratory Screening Genetic Analyses –Conducted in 5 labs for all 2100 WECARE Study participants (US, Norway, and Sweden) –Staged approach: DHPLC followed by direct sequencing –All conditions, primers standardized across labs –Inter- and Intra-lab QC implemented (Bernstein, …, Concannon, Hum Mut 2003)

Communication Through-out Study Working Group Communication during field work- Constant –Within Group Bi-monthly conference calls Monthly data delivery and progress reports Dedicated web-site –Between Group Annual/ semi-annual key investigator meetings
Central Informatics Management System Functional domains –Tracking database – every phase and every aspect of study on individual level and triplet level –Database for storage, cleaning and maintain data acquired through data collection instruments –Mutation screening database – screening process and results –Long term storage and access –Secures confidentiality CIMS links and maintains data from all sources and tracks all information so it is instantly available.
Summary: Challenges Study set up is key– anticipate the type of informatics that will be needed and plan ahead; Involve trained personnel, including informatics specialists, data managers and editors (for both lab and epi data); Over-communicate throughout the study, especially if the study involves scientists from diverse geographic regions; Plan in advance to maintain the infrastructure, even as the study is winding down.
