Screening for @entity2 produces two groups of @entity2 . Baseline cases include all prevalent cases with the expectation that slower-growing @entity5 and those that have achieved higher stage will be found in greater frequency. Repeat examination is expected to detect those @entity5 which have crossed the threshold for detection during the screening interval - 1 year in this study - and these are typically more rapidly growing @entity5 . The two groups encompass the full spectrum of @entity2 . Comparison of the baseline and annual repeat cases revealed differences in types of @entity2 . There were 202 baseline-detected @entity5 spanning the spectrum of @entity2 with some slowly growing, some rapidly progressive and some at high stage; the 48 @entity5 also included a spectrum of @entity2 but with more of the rapidly growing types, and more closely approximated the clinical spectrum of @entity2 . The NE @entity189 showed this trend best; @entity4153 were under-represented and typical @entity4303 were only found in the baseline group. Repeat @entity5 were found to grow rapidly, were typically smaller, less often multiple and the @entity420 were less often pure BAC and less frequently contained a BAC component when invasive. The baseline @entity420 included most of the BAC's, which is a diagnosis that requires special attention to its WHO definition. @entity36393 was found to be frequently associated with @entity420 , particularly BAC. Both baseline and annual repeat cases had a high percentage of invasive @entity189 with comparably high rates of resectability, high rates of node negativity and consequently a high proportion of cases in low stage.
