Aims-To audit the information content of pathology reports of colorect
al cancer specimens in one National Health Service region. Methods-All
reports of colorectal cancer resection specimens from the 17 NHS hist
opathology laboratories in Wales during 1993 were evaluated against: (
a) standards previously agreed as desirable by pathologists in Wales;
and (b) standards considered to be the minimum required for informed p
atient management. Results-1242 reports were audited. There was notabl
e variation in the performance of different laboratories and in the co
mpleteness of reporting of individual items of information. While many
items were generally well reported, only 51.5% of rectal cancer repor
ts contained a statement on the completeness of excision at the circum
ferential resection margin and only 30% of all reports stated the numb
er of involved lymph nodes. All of the previously agreed items were co
ntained in only 11.3% of reports on colonic tumours and 4.0% of report
s on rectal tumours. Seventy eight per cent of colonic carcinoma repor
ts and 46.6% of rectal carcinoma reports met the minimum standards. Co
nclusions-The informational content of many routine pathology reports
on colorectal cancer resection specimens is inadequate for quality pat
ient management, for ensuring a clinically effective cancer service th
rough audit, and for cancer registration. Template proforma reporting
using nationally agreed standards is recommended as a remedy for this,
along with improved education, review of laboratory practices in the
light of current knowledge, and further motivation of pathologists thr
ough their involvement in multidisciplinary cancer management teams.
