Improving Central Cancer Registry Surveillance through Interstate Data Exchange of Electronic Pathology Reports.

When a cancer case is diagnosed or treated in one US state, but the patient resides in another, the case report abstract is shared with the central cancer registry in the state of residence through interstate data exchange. However, the records shared may not include pathology reports. Cases diagnosed in another state that would be ascertained only from pathology reports may thus be missed. Utah Cancer Registry received many electronic pathology (e-path) records for nonresident cases that were not being shared. In 2019, Utah Cancer Registry implemented workflow changes and created a novel data extract process to share e-path records in a North American Association of Central Cancer Registries (NAACCR) HL7 format. Utah Cancer Registry shared e-path records for an estimated 2,773 cases with other states for the diagnosis year 2018. Of these cases, both an e-path record and NAACCR-format abstract were shared for 1,709 (61.6%), whereas e-path record only was shared for 1,064 (38.4%). The largest number of e-path records went to 2 adjacent states: Idaho (n = 1,084) and Wyoming (n = 621). Receiving registries reported success importing the files. The e-path data stream resulted in ascertainment of 96 new cases for Idaho and 89 for Wyoming for diagnosis year 2018. Whereas most shared e-path records represented cases already known to the receiving registry, registry staff provided feedback that it was beneficial to obtain the additional documentation. Linking and reviewing the shared e-path records did represent additional workload. Central cancer registries can adopt this process for sharing e-path records via interstate data exchange to support complete case ascertainment in collaborating states.

Cancer incidence in Montana: rates for American Indians exceed those for whites.

OBJECTIVES: Previous studies suggested that the cancer incidence rates in American Indians and Alaska Natives were lower than in other groups. The objective of this study was to compare the cancer incidence rates in American Indians and whites in Montana. METHODS: Age-adjusted 6-year cancer incidence rates were calculated for American-Indian and white men and women in Montana to allow comparison of rates in 1991-1996 to those in 1997-2002. RESULTS: The age-adjusted rates for American-Indian men were significantly higher than those for white men for all cancer sites (755+/-74 [95% confidence interval] per 100,000 vs 544+/-9 per 100,000), lung cancer (167+/-35 per 100,000 vs 83+/-4 per 100,000), and colorectal cancer (115+/-29 per 100,000 vs 61+/-4 per 100,000) from 1997 to 2002. The adjusted rates for American-Indian women were significantly higher than those for white women for all cancer sites (526+/-47 per 100,000 vs 412+/-8 per 100,000) and lung cancer (120+/-24 per 100,000 vs 56+/-3 per 100,000) during this same time period. There was a significant increase in the age-adjusted rates for all cancer sites among white men and women but not for American-Indian men or women between 1991-1996 and 1997-2002. CONCLUSIONS: There is a significant disparity in the cancer incidence rates between American Indians and whites in Montana. Regional or state-level surveillance data will be needed to describe the changing patterns of cancer incidence in many native communities in the United States.
