An Observational Follow-Up Study of the Incidence of Cancer and Mortality in Patients From the SEAS (Simvastatin and Ezetimibe in Aortic Stenosis) Trial (MK-0653A-043-10)

Completed

Brief Summary: The purpose of this extension is to observe the incidence rates of cancer, total mortality, and mortality due to cancer over a 21 month follow-up period in patients from the SEAS trial (2004_050, MK0653A-043; NCT00092677).

Detailed Description: The SEAS Follow-up Study is a 21 month extension to the base protocol (2004_050, MK0653A-043; NCT00092677). The main objective of the extension is to observe the incidence rates of cancer, total mortality, and mortality due to cancer over a 21 month follow-up period (from 04-March 2008 to 31-December 2009) in patients from the SEAS clinical trial. The sources of study data will include data collected from national cancer and death registries as well as data from the original clinical trial. No patient visits will occur. National cancer and death registries exist in 5 of the 7 countries that participated in the base SEAS trial. At the time of Follow-up study initiation, accessing the registry data in Ireland was not feasible due to local regulations and Cancer and Death registries did not exist in Germany. As a result, data will be collected only for all SEAS patients known to be alive at the end of the base study originating from Sweden, Denmark, Norway, Finland, and the United Kingdom.

Recruitment & Eligibility

Inclusion Criteria

The cohort will include all patients from the five participating countries (Sweden, Denmark, Norway, Finland, and United Kingdom) who were randomized into the SEAS base study and who were known to be alive at the end of the base study

Primary Outcome Measures

Name	Time	Method
Crude Rate of Newly Diagnosed Cancer-Follow-up Primary Cohort	up to 21 Months after the end of the SEAS (base) study	Any incidence of cancer reported during follow-up that was assessed by the Expert Review Committee to be a new case of cancer. The crude new cancer rates for each arm were calculated as follows: Number of participants in the arm was multiplied by the Duration of Follow-up (days) and divided by 365 (days per year) to establish the Total Participant-years for the arm. The Number of New Cancers reported was then divided by the Total Participant-years and the resultant quotient was then multiplied by 100 to determine the Crude New Cancer Rate.

Secondary Outcome Measures

Name	Time	Method
Crude Rate of Death Due to Cancer - Follow-up Primary Cohort	up to 21 Months after the end of the base study	All deaths reported during follow-up were reviewed by the Expert Review Committee to ascertain if cancer was cause of death. The crude rates of death due to cancer for each arm were calculated as follows: Number of participants in the arm was multiplied by the Duration of Follow-up (days) and divided by 365 (days per year) to establish the Total Participant-years for the arm. The Number of Deaths due to Cancer reported was divided by the Total Participant-years and the resultant quotient was then multiplied by 100 to determine the Crude Rate of Death Due to Cancer.
Crude Rate of Death (Any Cause) - Follow-up Total Cohort	up to 21 Months after the end of the base study	All deaths reported during follow-up were reviewed by the Expert Review Committee to ascertain cause of death. The crude rates of death for each arm were calculated as follows: Number of participants in the arm was multiplied by the Duration of Follow-up (days) and divided by 365 (days per year) to establish the Total Participant-years for the arm. The Number of Deaths (any cause) reported was divided by the Total Participant-years and the resultant quotient was then multiplied by 100 to determine the Rate of Death.
