# SUMMARY:

                        Under the provisions of Section 3507(a)(1)(D) of the Paperwork Reduction Act of 1995, the National Cancer Institute (NCI), the National Institutes of Health (NIH) has submitted to the Office of Management and Budget (OMB) a request for review and approval of the information collection listed below. This proposed information collection was previously published in the                         **Federal Register**                         on December 28, 2000, pages 82382-82383 and allowed 60 days for public comment. No public comments were received. The purpose of this notice is to allow an additional 30 days for public comment. The National Institutes of Health may not conduct or sponsor, and the respondent is not required to respond to, an information collection that has been extended, revised, or implemented on or after October 1, 1995, unless it displays a currently valid OMB control number.                    

*Proposed Collection: Title:*                        Case-Cohort (formerly Case-Control) Study of Cancer and Related Disorders Among                               ( print page 23035)                            Benzene-Exposed Workers in China, OMB Number 0925-0454, Revised.                         *Need and Use of Information Collection:*                        A case-cohort study will be performed to examine the risks of lymphohematopoietic cancers, other lymphohematopoietic disorders, benzene poisoning, and lung cancer among workers exposed to benzene. The study will attempt to determine with greater precision the risks of these disorders at low levels of benzene exposure, and to characterize the dose and time-specific relationship between benzene exposure and disease risk. Cases and controls will be selected from an existing cohort of 75,000 benzene-exposed workers and 36,000 comparison workers in 12 Chinese cities. There are 3 changes to the 60-day                         **Federal Register**                         notice for this study published on December 28, 2000: (1) more subjects will be evaluated in the currently planned case-cohort study (N=1,770, including 225 with benzene poisoning) than in the previously described case-control study (N=1,545); (2) each subject (or their next of kin will be asked fewer questions (average hours per response will decrease from 0.42 to 0.3674 hours); and (3) the more efficient case-cohort design will be used, rather than an individually-matched case-control study design.                         *Frequency of Response:*                        Single-time study.                         *Affected Public:*                        Individuals or households.                         *Type of Respondents:*                        Cases with lymphohematopoietic malignancies and related disorders, benzene poisoning and lung cancer among Chinese benzene-exposed and comparison workers; controls consist of a random sample of the Chinese worker cohort without these disorders. The annual reporting burden is as follows:                         *Estimated Number of Respondents:*                        590;                         *Estimated Number of Respondents per Respondent:*                        1;                         *Average Burden Hours per Response:*                        0.3674; and                         *Estimated Total Annual Burden Hours Requested:*                        216. The annualized cost to respondents is estimated at $216. 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 or 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.                    

*Direct Comments to OMB:*                        Written comments and/or suggestions regarding the item(s) contained in this notice, especially regarding the estimated public burden and associated response time, should be directed to the: Office of Management and Budget, Office of Regulatory Affairs, New Executive Office Building, Room 10235, Washington, DC 20503, Attention: Desk Officer for NIH.
