Endometrial epithelial cell expression of CSF-1 and FMS antigens was studied in vivo and in vitro in 24 human endometrial carcinoma and 11 benign endometrial biopsy specimens. Twenty-one of 24 adenocarcinomas and 4 of 11 benign lesions stained positively (by IHC) with rabbit anti-human CSF-1 antibodies, while all 24 carcinomas and 3 out of 11 benign lesions (all secretory endometrial specimens) showed significant IHC staining (1+ or greater) of epithelial elements and tissue macrophages with a mouse anti-FMS (CSF-1 receptor) monoclonal antibody. CSF-1 levels in plasma from endometrial carcinoma patients (85 samples, 24 patients) were also found to be markedly elevated (some greater than 100 ng/ml) in patients with active or recurrent disease. In vitro, several endometrial carcinoma cell lines were shown to express FMS complementary transcripts and FMS antigen which were very similar if not identical to those expressed in choriocarcinoma cell line positive controls. Autocrine and paracrine effects mediated by tumor or stromally produced CSF-1 and a tumor epithelial cell CSF-1 receptor may therefore contribute to the biological behavior of endometrial neoplasms in vivo and in vitro.

Two kinds of clones were isolated successfully from the HHUA 95 cells that were derived from a human well-differentiated adenocarcinoma of endometrium, with 6-thioguanine (6-TG) selection and transfection with plasmid containing the neo gene (pSV2 neo). One clone was resistant to the 6-TG (6-TGr 95) and the other to both the 6-TG and the G418 (6-TGr-neor 95). Karyotypes of these three kinds of cells were normal, even though random chromosome abnormalities were observed in some cells. Two types of cell fusion were performed: one consisted of the hybridization between 6-TGr 95 cells and normal human fibroblasts (HF), and the other, between 6-TGr-neor 95 and human choriocarcinoma cells (CC1). Tumorigenicity of both hybrid cell types was completely suppressed. Complementation for genetic lesions given by cell hybridization was assumed to be responsible for the suppression of tumorigenicity. These results suggest that genetic losses played an essential role in the evolution of the malignant phenotype of endometrial carcinoma cells. The data obtained from the endometrial carcinoma could not be used directly for the understanding of suppression mechanisms of choriocarcinoma.

Sensitivity of cultured choriocarcinoma cell lines to tumor necrosis factor (TNF)-alpha and interferon (IFN)-gamma was examined and compared with that of other cultured tumor cell lines. Tumor cells were cultured with 1,000 mu/ml of TNF-alpha and/or 100 mu/ml of IFN-gamma for 24hr. Antitumor effects of the lymphokines were measured by 3H-thymidine uptake and tetrazolium salt (MTT) colorimetric assay. The results revealed that TNF-alpha and/or IFN-gamma had little anti-tumor effect on the choriocarcinoma cell lines tested, while they had cytostatic and cytotoxic effects on other cultured tumor cell lines including Panc-1 (pancreatic carcinoma cell line), Lovo (colon carcinoma cell line) and Ishikawa (uterine endometrial carcinoma cell line). We also examined the effect of TNF-alpha and IFN-gamma on the expression of major histocompatibility complex (MHC) class I antigens in these tumor cell lines by means of cellular binding radioimmunoassay. No enhancing effect was observed on choriocarcinoma cell lines after the treatment with TNF-alpha and/or IFN-gamma. These results suggested the existence of a unique property of choriocarcinoma cells which results in the resistance to host immune attacks.

Seventy-four cases of gynecologic tumor; 29 of the endometrium, 20 of the ovary, 9 of the trophoblastic, 7 of the cervix, 2 of the fallopian tube and one of the vulva, and 6 of malignant ascites, were transplanted into nude mice. 1. Overall success rate at the trial of primary transplantation revealed 35.1% or 26 cases out of 74. Trophoblastic neoplasia appeared the highest in the rate among each tumors, showing 55.5% of 9 trials. 2. Out of 26 successful cases of the primary trials, 14 or 53.8% are serially transplantable. These consisted of 7 endometrial, 2 ovarian, 3 choriocarcinoma and 2 cervical carcinomas. 3. The serially transplantable tumors are reproducible of the morphology of each original tumor. 4. The doubling times of the tumor size in choriocarcinoma are evenly short although life span of the tumor-bearing mice varies from each other. Endometrial and ovarian carcinomas spend the time longer than choriocarcinoma. The doubling times differ from each case of endometrial carcinoma with the same histological grade. 5. Choriocarcinoma lines preserve hCG secreting ability. Tumor size of the choriocarcinoma originated from the kidney correlates well with its serum hCG titer. These lines of gynecologic malignancy serially transplantable in nude mice will be useful for further cancer research.

This study was based on clinical and histological diagnosis of 1251 consecutive cases, referred to Harare Central Hospital for Specialist attention between January 1981 and December 1983. The frequency of each gynaecological malignancy was as follows: cervix - 78%, choriocarcinoma - 8%, endometrial carcinoma - 6%, ovarian carcinoma - 5%, vulva and vagina - 3%. The study showed that cancer of the cervix was the commonest type in African women who were 99% semiliterate rural women of low socio-economic status and who presented in 76% of the cases with advanced malignancy. It was concluded that the most practicable way of preventing cervical cancer in African women is intensive health education in rural areas to make women aware of the early symptoms of the disease.

With flow-cytometry we tested whether or not interferon can induce surface expression of HLA-ABC antigen on cell lines derived from various gynecologic cancers. The tumor cell lines used were Hela S3 derived from cervical cancer, OVK-18 derived from ovarian cancer, HHUA derived from endometrial cancer, SCH, JaR and BeWo derived from choriocarcinoma. 1000 IU/ml of interferon-gamma induced HLA-ABC antigen expression on Hela S3, OVK-18 and SCH but not on BeWo. HLA-ABC antigen was expressed on neither the surface of HHUA or JaR nor was its appearance induced by interferon. The clinical application of interferon may be effective in killing some tumors, taking advantage of the increased expression of HLA antigen.

In order to determine whether trophoblast (or gestational choriocarcinoma) expresses the HLA-DR antigen or not, it was analysed using human gestational choriocarcinoma cell lines (GCH-1, GCH-1(m) and TAK-N) by the Northern hybridization method. TYK-nu (human undifferentiated ovarian carcinoma cell line), M-14 (human malignant melanoma cell line), L-14 (human B lymphocyte cell line), and KKNS-1, KKNS-2 and KKNS-3 (three human endometrial carcinoma cell lines) were also examined. Messenger ribonucleic acids (mRNAs) were prepared from 2 X 10(7) cells in each cell line and hybridized by HLA-DR alpha-chain complementary deoxyribonucleic acid (cDNA) probe (pDR alpha-1) and beta-chain cDNA probe (DK-10). Northern hybridization analysis revealed that GCH-1 transcribed at least two kinds of alpha-chain (16s and 23s) and beta-chain mRNA (15s and 23s). TYK-nu transcribed alpha- and beta-chain mRNA, L-14 transcribed only alpha-chain mRNA, and TAK-N appeared to transcribe only a little alpha-chain mRNA. The HLA-DR molecules were not, however, expressed in the other cell lines (GCH-1(m), M-14, KKNS-1, -2 and -3). These results are compared with those obtained by immunocytochemical methods in our laboratory.

For the purpose of analysis of cancer specific immune reactions in gynecological malignancies, Leucocyte Migration Inhibition Test (LMIT: agarose-plate method) has been examined with tumor extract. Tumor extracts as antigens were prepared from 27 cases of cervical cancer, 14 of ovarian cancer, 4 of endometrial cancer, 4 of choriocarcinoma, 3 of vulval cancer and 3 of uterine sarcoma as well as control tissue extracts by hypertonic potassium chloride method (3 M-KCl method). The same antigens were also used for skin reaction test and leucocyte adherence inhibition (LAI) assay. 1. LMIT The positive reaction with autochthonous tumor extracts were 6/27 (22.2%) cases in cervical cancer, 4/14 (28.6%) in ovarian cancer, 1/4 in endometrial cancer, 1/4 in choriocarcinoma, 0/3 in vulval cancer, 1/3 in uterine sarcoma. But their reactions with control tissue extracts were all negative. Only a case of ovarian cancer and another of endometrial cancer with cancer extracts of the same types showed positive reaction. 2. Correlations of among LMIT, LAI and skin reaction--Positive reactions of LAIs and skin reactions which were simultaneously examined using the autochthonous tumor extracts were 0-60% in gynecological malignancies. The results yielded the agreement rate with LAI of 77.8%, and that with skin reaction of 55.6%. 3. The antigeneic localization of tumor extract--We gained 3 fractions from the cervical cancer extract, which was LMIT-positive, by Sephadex G-200 gel column chromatography. The antigenicity of the extract was found to be in the high molecular weight fraction.

Methotrexate (MTX) was covalently bound to rabbit antibodies (IgG) against hCG and placental alkaline phosphatase (PLALP) by two different methods. By carbodiimide method, 16.9 mols of MTX could be coupled to one mol of IgG, but the antibody activity was completely lost. Whereas, 2.6-3.4 mols of MTX were bound to one mol of IgG and a quarter of original antibody activity was preserved by dextran bridge method. Choriocarcinoma cells BeWo and SCH were exposed to the IgG-MTX conjugates prepared by the latter method for 30 minutes, and the cell growth was investigated. To BeWo, which produces much hCG and less PLALP, anti hCG-IgG-MTX showed a considerable growth inhibition compared to the control groups (p less than 0.05). No effect was observed with anti PLALP-IgG-MTX, nonimmunized IgG-MTX, free MTX and anti hCG-IgG. In contrast, to SCH, which produces much PLALP and less hCG, anti PLALP-IgG-MTX exhibited considerable inhibition (p less than 0.05), whereas anti hCG-IgG-MTX showed no inhibition. Neither anti hCG-IgG-MTX nor anti PLALP-IgG-MTX showed any effect to the endometrial carcinoma cell HEC50B. We concluded that MTX bound to anti hCG-IgG and anti PLALP-IgG have specific growth inhibition effects to the choriocarcinoma cells in vitro, and suggested the possibility of specific immunochemotherapy of this disease.

The effects of chemotherapy for lung metastasis in 284 cancer patients using various anti-tumor drugs, including classic ones and modern active agents for the past 18 years, were presented. Lung metastasis for lung cancer was excluded. The response was achieved in cervical carcinoma of the uterus (17/62, 27%), endometrial carcinoma of the uterus (1/7, 14%), colorectal cancer (6/39, 15%), breast cancer (5/28, 18%) and stomach cancer (4/28, 14%). A high response was achieved in myosarcoma (5/12, 42%), testicular cancer (5/11, 45%) and also in ovarian cancer (3/10, 30%). Though there were few cases, a high response was achieved in malignant melanoma (2/3), choriocarcinoma (2/4) and esophageal cancer (1/3). In total patients the response rate was 20%. In these cases a complete response was achieved in 4 cervical cancers; one testicular cancer, ovarian cancer, esophageal cancer and renal cancer, respectively. However, the effect was temporary and no longterm survivor was observed except for one case of renal cancer treated continuously with interferon (3 X 10(6) units daily) and showing complete remission after 7 months of therapy. The effect of chemotherapy for lung metastasis was compared between nodular metastasis (NM) and lymphagiosis carcinomatosa (LC). In cervical carcinoma of the uterus, the response rate in NM (39%) was higher than in LC (11%). However, no difference was observed in breast cancer (NM 15%, LC 13%) nor in stomach cancer (NM 13%, LC 18%).
