Compared with previously reported cohorts from Europe and North America using the same AS selection criteria, we found significantly higher rates of upgrading and upstaging.
New upgrades cost different combinations of resources, and can do anything from improving a civilization's fishing rate to upgrading units with enhanced technology.
Distanced from public systems, committed bottled water drinkers have little incentive to support bond issues and other methods - including rate increases - of upgrading municipal water treatment.
Capital consideration: the rate of upgrade in medical instruments runs too high for hospitals to afford.
The rate of upgrade to a more significant pathology was 10% (on provisional data, complete results will be presented) with significant pathology being DCIS of varying grade.
Surgical excision of FEA at our centre has resulted in a low rate of upgrade to malignancy supporting current thinking that some lesions may be managed by vacuum excision, thus reducing the surgical diagnostic excision rate.
Individually, each of our three centres has a relatively high rate of GS upgrading (Table 4, Cambridge 44%, Vancouver 47%, Melbourne 62%).
Associations between patient characteristics and rates of upgrade were determined by univariate and multivariate logistic models, and times to diagnosis carcinoma were calculated.
The rates of upgrade to malignant disease after histological analysis of open surgical excision samples for the various image-guided VAB procedures are listed in Table 4.
Prior series have shown rates of upgrade to DCIS or invasive carcinoma ranging from 1% to more than 40% of cases on excision after the diagnosis of ALH or LCIS on core biopsy 22– 22.
