2Study on the prevalence of cholangiocarcinoma in veterans who served in the Vietnam theater of operations during the Vietnam era

This section would require the Secretary of Veterans Affairs, in consultation with the Director of the Centers for Disease Control and Prevention, to start an epidemiological study no later than 120 days after the bill becomes law. The study would look at how common cholangiocarcinoma is among covered veterans of the Vietnam era, using data from the Veterans Affairs Central Cancer Registry and the National Program of Cancer Registries. The study would have to identify the rate of cholangiocarcinoma among covered veterans of the Vietnam era and among residents of the United States generally, covering the period from the start of the Vietnam era through the date the bill becomes law. For each of those two groups, the study would also have to identify the percentage of people with cholangiocarcinoma broken down by age, gender, race, ethnicity, and the geographic location of the patient at the time of diagnosis. No later than one year after the study is completed, the Secretary would have to submit an initial report to Congress containing the results of the study and recommendations for administrative or legislative action needed to address issues the study identified. After the initial report, the Secretary would have to periodically submit follow-up reports to Congress, on a schedule the Secretary determines, to update the information in the initial report and to report information collected under the continued tracking requirement. The Secretary would also have to keep tracking the prevalence of cholangiocarcinoma in covered veterans of the Vietnam era using the Veterans Affairs Central Cancer Registry, and include that information in the follow-up reports to Congress. For purposes of this section, Vietnam era would have the meaning given that term in section 101 of title 38, United States Code, and covered veterans of the Vietnam era would mean veterans who served in the Vietnam theater of operations during the Vietnam era.
