To measure the quality of pathology reporting of breast cancer and establis
h a baseline against which future changes can be measured, we audited item
completeness in breast cancer reports in Australia in 1995 before the relea
se of specific recommendations from the Australian Cancer Network. Tumour t
ype and size were given in reports of invasive breast cancer for 93% of wom
en, 70% had, in addition, grade and clearance of the margins while only 28%
had all recommended information. The most complete items in reports were h
istological type of breast cancer (99.6% of cases), tumour size (94%, 95% c
onfidence interval (CI) 92-95) and margins of excision (87%, 95% CI 85-89).
Histological grade (84%, 95% CI 82-86 of cases) and presence or absence of
ductal carcinoma in situ (DCIS) (79%, 95% CI 77-81) were less complete and
vessel invasion (61%, 95% CI 58-63) and changes in non-neoplastic breast t
issue adjacent to the breast cancer (68%, 95% CI 66-71) the least complete.
Less than half the reports of DCIS reported on tumour size (49%, 95% CI 42
-57), presence or absence of necrosis (41%, 95% CI 34-49) or nuclear grade
(39%, 95% CI 31-46). Around 1500 reports were identified as issued by 147 l
aboratories and 392 pathologists; 69% of pathologists issued fewer than two
reports a month in the audit. We concluded that infrequency of reporting m
ay have contributed to incompleteness of reporting. In addition, we found s
ignificant variation across Australian states with some indication that rep
orting was consistently poor in one state. The audit highlighted areas for
improvement for breast cancer reporting in Australia. Research evidence sug
gests that multifaceted strategies are needed to assist practitioners with
implementing more uniform reporting standards.
