Sensitivity of interview as a means of identifying familial cancer cases, by site
| Site | Relative group | No of cases* | No of cases correctly reported | Sensitivity of interviewee report (95% CI) |
|---|---|---|---|---|
| *Where more than one primary cancer occurred at the same site, it was not possible to determine whether the interviewee was aware of both of these tumours. Therefore, where metachronous primary cancers occurred, only the first is considered. | ||||
