    Notes: Aims:  The Goseki grouping of gastric adenocarcinoma has been suggested as a possible prognostic factor. In those centres where it is used, it may be valuable to assess the Goseki grouping of a tumour on the initial diagnostic biopsy as well as on the resection specimen since it may in theory influence management. We examined the robustness of Goseki grouping of gastric adenocarcinoma in representative sections from resection and biopsy specimens in order to assess the consistency of agreement among a group of pathologists.Methods:  A single representative block from 100 gastric resection specimens was studied using a haematoxylin and eosin and mucin (alcian blue/periodic acid–Schiff) stain. These were circulated in batches to members of a group of 12 pathologists who each completed a simple proforma confirming the presence of carcinoma and assigning a Goseki group. In a second circulation the diagnostic biopsy specimen taken prior to resection was examined in the same way. This allowed comparison of the Goseki group of the biopsy and resection specimens.Results:  In both studies κ statistics showed good agreement on tubular differentiation of the carcinoma, but only moderate agreement for the intracellular mucin production, resulting in moderate agreement for the final Goseki group. Correlation between the Goseki group assigned on the biopsy and resected specimens was seen in 62% of the cases. However, the reproducibility was low (κ 0.375).Conclusions:  The Goseki grouping of resected gastric adenocarcinoma is reproducible and can be used in prognostication. Goseki grouping of biopsy specimens is of limited value in predicting the Goseki group assigned to the resected carcinoma.

    Consistency of histopathological reporting of laryngeal dysplasia (2000)

    Notes: AimsClinical management of premalignant and malignant lesions of the larynx is dependent on histopathological evaluation. The Scottish Pathology Consistency Group assessed interobserver variation in the evaluation of laryngeal dysplasia.Methods and resultsOne hundred laryngeal biopsies ranging from normal to invasive carcinoma were assessed. The overall Kappa result of 0.32 was disappointing. However, agreement on those categories which dictate significantly different management was more favourable. The Kappa figure for mild dysplasia versus severe dysplasia/CIS was 0.7, the Kappa figure for mild dysplasia versus severe dysplasia/CIS and invasive carcinoma was 0.77. The Kappa figure for mild and moderate dysplasia versus severe dysplasia/CIS and invasive carcinoma was 0.57. An attempt to use a two grade system gave a Kappa figure of 0.52.ConclusionsOur group had a satisfactory agreement on the distinction of mild from severe dysplasia and on microinvasive carcinoma without any discussion as to histopathological criteria to be used. Clinical management — review endoscopy, repeat cord stripping, radiotherapy and laryngectomy — is in general dependent on histological assessment. Thus the agreement on categories which underpin clinical management is reassuring. However, assessment of moderate dysplasia remains problematic. An attempt to utilize a two grade system — low grade from high grade dysplasia/CIS — may have merit. The implications of the terminology used must be agreed among pathologists and clinicians working closely within clinicopathological cancer groups.

    Is biopsy necessary if colonoscopy is normal? (1987)

    Notes: Abstract Multiple endoscopic biopsies were taken from 100 consecutive patients who had a macroscopically normal colon at colonoscopy. Of these, 78 were regarded as histologically normal; 13 cases of melanosis coli, 7 cases of intestinal spirochetosis, and 2 cases of collagenous colitis were identified. In no cases was there histologic evidence of inflammatory bowel disease. Histologic abnormality could not be predicted by retrospective analysis of various clinical, hematologic and biochemical data. In individual subjects the microscopic abnormality was present to a varying degree in all biopsies, except in intestinal spirochestosis where patchy distribution occurred in some subjects. It is therefore concluded that significant pathology may be missed without biopsy of the apparently normal colon, but in order to reduce the workload of pathology departments and shorten the duration of the examination two biopsies from the hepatic flexure and sigmoid colon may be adequate.
