Start Preamble


In compliance with the requirement of section 3506(c)(2)(A) of the Paperwork Reduction Act of 1995, for opportunity for public comment on proposed data collection projects, the National Institute of Environmental Health Sciences (NIEHS), the National Institutes of Health (NIH) will publish periodic summaries of proposed projects to be submitted to the Office of Management and Budget (OMB) for review and approval.

Proposed Collection: Title: The Sister Study: A Prospective Study of the Genetic and Environmental Risk Factors for Breast Cancer. Type of Information Collection Request: Revision of OMB No. 0925-0522 and expiration date 31 July 2006. Need and Use of Information Collection: The purpose of the Sister Study is to study genetic and environmental risk factors for the Start Printed Page 9359development of breast cancer in a cohort of sisters of women who have had breast cancer. In the United States, there were approximately 210,000 new cases in 2003, accounting for 30% of all new cancer cases among women. The etiology of breast cancer is complex, with both genetic and environmental factors likely playing a role. Environmental risk factors, however, have been difficult to identify. By focusing on genetically susceptible subgroups, more precise estimates of the contribution of environmental and other non-genetic factors to disease risk may be possible. Sisters of women with breast cancer are one group at increased risk for breast cancer; we would expect about 2 times as many breast cancers to accrue in a cohort of sisters as would accrue in a cohort identified through random sampling or other means. In addition, a cohort of sisters will be enriched with regard to the prevalence of relevant genes and/or exposures, further enhancing the ability to detect gene-environment interactions. Sisters of women with breast cancer will also be at increased risk for ovarian cancer and possibly for other hormonally-mediated diseases. We are enrolling a cohort of 50,000 women who have not had breast cancer. Initial recruitment of the first 2,000 women took place from August 2003-September 2004 before beginning nationwide recruitment in October 2004. The data collected in the initial phase allowed us to evaluate subject recruitment and data collection procedures, and helped us better target our recruitment efforts. We estimate that a cohort of 50,000 sisters aged 35-74 years would provide about 1,500 breast cancer cases over five years (approximately 300 new cases per year once the cohort is fully enrolled). Frequency of Response: At enrollment, one initial 15-minute screening (either on the telephone OR on the internet), 2 one-hour telephone interviews, 3 mailed self-administered questionnaires (90 minutes total), and some biological and household specimens collected. Women are advised that they will be contacted every year to update contact information and health status and asked to complete shorter (45-60 minutes, total) follow-up interviews or questionnaires every two years. Women diagnosed with breast cancer or other health outcomes of interest will be asked to provide additional information about their diagnosis (20 minutes per response) and their doctors will be contacted to provide documentation regarding diagnosis and treatments (15 minutes per response). Affected Public: Individuals or households; doctors' offices. Type of Respondents: Unaffected sisters of women diagnosed with breast cancer, aged 35-74, from all socioeconomic backgrounds and ethnicities. The annual reporting burden is as follows: Estimated Number of Respondents: 67,500 (~12,500 enrolled per year over ~4 years, plus ~14,000 persons ultimately determined ineligibles or refusals at initial screening, and 3,500 persons who partially complete enrollment before terminating). Estimated Number of Responses per Respondent: See table below. Average Burden Hours per Response: 6.0; and Estimated Total Burden Hours Requested: 176,553 (over 3 years). The average annual burden hours requested is 58,851. The annualized cost to respondents is estimated at $135 (assuming $20 hourly wage × 6 hours + $15 babysitting estimate). There are no Capital Costs to report. There are no Operating or Maintenance Costs to report.

Request for Comments: Written comments and/or suggestions from the public and affected agencies are invited on one or more of the following points: (1) Whether the proposed collection of information is necessary for the proper performance of the function of the agency, including whether the information will have practical utility; (2) The accuracy of the agency's estimate of the burden of the proposed collection of information, including the validity of the methodology and assumptions used; (3) Ways to enhance the quality, utility, and clarity of the information to be collected; and (4) Ways to minimize the burden of the collection of information on those who are to respond, including the use of appropriate automated, electronic, mechanical, or other technological collection techniques or other forms of information technology.
