    Notes: In FIGO stage I endometrial cancer patients, histologic type and grade are correlated with prognosis and used for therapeutic decision making. However, assessment of these histologic features is subjective, and the results are not always perfectly reproducible. Contrarily, previous studies have shown that DNA-ploidy and morphometric features are highly reproducible and have a strong prognostic value in these cancers. Multivariate analysis has demonstrated that a combination of mean shortest nuclear axis (MSNA), DNA-ploidy and depth of myometrial invasion (the so-called ECPI-1 score) overshadowed the value of all other features investigated. The present study was set up to evaluate further and compare the prognostic power of the ECPI-1 score in 77 FIGO I patients with long follow-up (10–15 years). Grade (revised), invasion depth, MSNA and ploidy were all highly significant. However, the ECPI-1 score (with exactly the same threshold as in the previous study, 0.87) greatly exceeded the prognostic value of these single features. Only two (3%) of the 64 patients with ECPI-1 〈inlineGraphic alt="leqslant R: less-than-or-eq, slant" extraInfo="nonStandardEntity" href="urn:x-wiley:1048891X:IJG05020112:les" location="les.gif"/〉0.87 died (at 14 and 62 months), in contrast to 11 (84.6%) of the 13 cases with ECPI-1〉 0.87 (10 died within 42 months) (P 〈 0.0001, Mantel-Cox value = 51.1). These results confirm the prognostic strength of the ECPI-1 score in stage I endometrial carcinoma.

    Notes: The effect of chemotherapy on the different components of uterine and ovarian carcinosarcoma is largely unknown. This report describes six patients with advanced carcinosarcoma, five of whom received 4 cycles of doxorubicin and ifosfamide (AI) directed at the sarcomatous component of the tumor. Responses in these five patients at second-look laparotomy were: one complete response, two partial responses (persistence of only the carcinomatous component), one stable disease, and one progressive disease (both components still present in both cases). Thereafter 4 cycles of a cisplatin-based regimen were scheduled. Response to the cisplatin-containing regimen was only evaluated clinically. The sixth patient (with no macroscopic disease left after initial surgery) received 6 cycles of a cisplatin-based chemotherapy from the onset and was found to be in complete response at relaparotomy. Median progression-free survival for all patients was 15 months and median survival 21 months. A literature survey showed that carcinosarcoma differs from adult soft tissue sarcomas with respect to responsiveness to chemotherapy. Cisplatin and ifosfamide are active as single agents, whereas the response to single-agent doxorubicin seems to be lower. The data suggest, however, that superior response rates and increased survival times are achieved with cisplatin/doxorubicin-based chemotherapy. The sensitivity of carcinosarcoma to cisplatin supports the recent view that carcinosarcoma of the female genital tract is possibly a high grade carcinoma with metaplastic sarcomatous elements.

    Notes: Aims:  To investigate the occurrence of preinvasive neoplastic lesions in ovarian surface epithelium and ovarian inclusion cyst epithelium of women with a hereditary predisposition to the development of female adnexal (ovarian and fallopian tube) carcinoma and to assess the expression of differentiation and proliferation related proteins within putative sites of origin of serous ovarian carcinoma, the ovarian surface epithelium and ovarian inclusion cyst epithelium.Methods:  Twenty-one ovaries, prophylactically removed from 11 women predisposed to the development of female adnexal cancer (cases) were compared with 22 ovaries from 11 women without such predisposition (controls). Archival histological specimens were screened for hyperplastic and dysplastic epithelial lesions. In both the ovarian surface and inclusion cyst epithelia, the percentage of cells was determined that stained positively for Ki67, p21, p27, p53, cyclin A, cyclin D1, bcl-2 and the presence of HER-2/neu, oestrogen (ER-α) and progesterone receptors (PR).Results:  No preinvasive neoplastic lesions were detected. However, hyperplastic areas were found in three cases and in four controls (NS). ER-α (P = 0.013), PR (P 〈 0.001), bcl-2 (P = 0.008), p21 (P = 0.046) and p27 (P = 0.008) were expressed in a significantly higher percentage of cells in inclusion cyst epithelium than in ovarian surface epithelium (both groups). The latter showed higher bcl-2 expression in cases (P = 0.05) compared with controls. The inclusion cyst epithelium of cases showed higher expression of bcl-2 (P = 0.006) and PR (P = 0.039) compared with controls. Proliferation was low in both cases and controls as reflected by low Ki67 expression. Over-expression of p53, cyclin D1 and HER-2/neu was not detected.Conclusions:  Premalignant changes are not a common feature of ovaries removed prophylactically from women predisposed to the development of female adnexal carcinoma. Increased expression of p21, p27, and ER-α is seen in inclusion cyst compared with ovarian surface epithelium of women with and without an inherited risk of adnexal carcinoma. This is most probably caused by the different intraovarian hormonal milieu of inclusion cyst epithelium. However, the increased expression of bcl-2 and PR in the inclusion cyst epithelium of patients with a hereditary predisposition may reflect early disruption of hormonal balance and growth control.

    Notes: Abstract The objective of this study was to demonstrate the presence of proliferative T cell responses to human polymorphic epithelial mucin (MUC1) and its tandem-repeat peptides in peripheral blood mononuclear cells (PBMC) from ovarian cancer patients and from controls and to correlate these cellular responses to a humoral response to MUC1. PBMC were obtained from 6 healthy women, from 13 women in the third trimester of pregnancy and from 21 ovarian cancer patients. Only 1 of the 6 healthy women showed a weak primary proliferative response (stimulation index, SI〈2) to a 20-mer MUC1 tandem-repeat peptide in the presence of interleukin-2 (IL-2). In PBMC from 5/13 pregnant women (38%) a weak response could be induced by the 20-mer and/or 60-mer tandem-repeat peptides (SI ≤ 3.0) and in PBMC from 8/15 ovarian cancer patients (53%) 20-mer and/or 60-mer MUC1 tandem-repeat peptides induced primary responses (SI ≤ 5.4). MUC1 mucin purified from a breast tumor cell line and/or from urine of a healthy donor had a relatively strong stimulating effect (SI ≤ 19) on PBMC from 4 of 16 ovarian cancer patients (25%). In contrast, in PBMC of 9 ovarian cancer patients stimulated by the addition of a Candida albicans extract, MUC1 mucin strongly inhibited proliferation. This inhibition could partially be abrogated by the addition of IL-2. MUC1 (CA 15.3 assay) and free circulating MUC1 IgG and IgM antibodies (PEM.CIg assay) were determined in the plasma of all subjects. The MUC1 and the free circulating MUC1 IgG antibody plasma levels were significantly higher in the ovarian cancer patients than in the healthy women. Although no significant correlations were found between MUC1 mucin, MUC1 Ab plasma levels and the individual proliferative responses to the MUC1 antigens, an association may exist between them, since all three are significantly higher in the ovarian cancer patients than in the healthy women.

    Prevalence ofChlamydia trachomatis infection in a population of asymptomatic women in a screening program for cervical cancer (1989)

    Notes: Abstract The prevalence ofChlamydia trachomatis infection in a population of women with no symptoms of sexually transmitted disease was investigated. These women, aged 35–55 years, participated in a screening program for cervical cancer. With the use of a direct immunofluorescence method, 109 out of 2,470 smears tested were positive forChlamydia trachomatis, indicating an overall prevalence of 4.4%. No changes in prevalence were found when five-year cohorts of this group were analyzed, indicating that age-dependent changes or epidemiological factors do not result in a different (decreased) prevalence over the ages 35 to 55 years. The prevalence ofTrichomonas vaginalis and fungi, as detected by cytological screening, was lower than that observed forChlamydia trachomatis: 3.1 and 2.1%, respectively. Of the 109 smears positive forChlamydia trachomatis, 90 showed cervical cells with reactive changes (out of 1,490 smears with PAP II), whereas no cytological changes were found in 15 cases (out of 884 smears with PAP I). Changes suggestive of mild or moderate dysplasia were found in only four cases (out of 93 smears with PAP III). The results indicate thatChlamydia trachomatis is associated with reactive changes of endocervical cells and raise serious questions about whether prevention of possible secondary effects such as infertility and pelvic inflammatory disease can be achieved by a combined screening program for cervical cancer andChlamydia trachomatis.
