The aim of this retrospective study was to examine the incidence and prognostic significance of abdominal wall metastases in pa tients with ovarian cancer present at the primary debulking at the entry sites of previous laparoscopy or paracentesis. The clinical records of 219 patients were studied. In 7 of 43 patients (16%) who had undergone laparoscopy and 3 of 30 patients (10%) who had undergone paracentesis previous to the primary debulking, an abdominal wall metastasis had developed at the entry sites. All metastases occurred in patients with FIG O stage IIIC -IV including ascites. Survival analysis using the Cox proportional hazards model showed that after adjustment for age, FIG O stage3 histology, grade, ascites, and residual disease after primary de bulking, the presence of abdominal wall metastases in the entry sites of previous laparoscopy or paracentesis was negatively, al though not statistical significantly, correlated with survival (P = 0.14).

We investigated the expression of keratin subtypes 7, 8, 10, 13, 14, 17, 18 and 19 in the normal cervix, in cervical intraepithelial neoplasia (CIN) lesions and in cervical carcinomas, using a selected panel of monoclonal keratin antibodies, reactive with routinely processed, formalin fixed paraffin embedded tissue fragments. The reaction patterns derived for each keratin antibody were compared with known expression patterns of the various epithelia, previously examined in frozen tissues. Although the reactivity of the antibodies was generally acceptable, considerable modifications to the manufacturers' staining instructions were often necessary. For some antibodies, which were previously thought to be reactive with fresh frozen tissue only, we developed staining protocols rendering them reactive with routinely processed material. As with previous findings in frozen sections we observed increasing expression of keratins 7, 8, 17, 18 and 19 with increasing grade of CIN. In cervical carcinomas the differences in keratin detectability between the main categories were more pronounced than in frozen sections, probably due to fixation and processing. For routine pathology, keratin phenotyping of cervical lesions may be of value in classification. The fact that keratin 7 was detected for the first time in reserve cells, and that this keratin was also found to be expressed in a considerable number of CIN lesions and cervical carcinomas supports the suggestion that reserve cells are a common progenitor cell for these lesions.
