Uterine papillary serous carcinoma (UPSC) is an aggressive malignancy that accounts for a disproportionate number of intraabdominal failures among endometrial carcinoma patients. The histologic appearance and tendency toward intraabdominal spread resemble those of papillary serous adenocarcinoma of the ovary. Because approximately 70% of untreated ovarian carcinoma patients respond to platinum-based chemotherapy, it has been suggested that UPSC patients might respond to similar treatment regimens. Twenty patients with UPSC were treated with cisplatin, doxorubicin (Adriamycin), cyclophosphamide (PAC) chemotherapy between January 1982 and December 1989. They included 9 patients with advanced primary disease, 5 with recurrence, and 6 who received PAC as adjuvant therapy. Patients received a mean of five cycles of PAC. Only 2 of 11 patients with measurable disease greater than 2 cm achieved complete clinical responses of 12 and 31 months duration; there were no partial responses. Actuarial 5-year survival for all patients was 23%. The mean progression-free interval was 9 months. Patients with clinical stages I or II disease had a higher survival rate than those with stage III or IV disease (P = 0.003). Survival did not correlate with depth of myometrial invasion (P = 0.81) or size of residual tumor following initial surgery (P = 0.16). Estrogen or progesterone receptors were detected in 10 of 11 tumors tested. Seven of 9 patients tested had elevated serum levels of CA-125 (greater than 35 U/ml). Correlation between CA-125 value and clinical course was demonstrated in 3 of 5 patients who had serial measurements. Of all patients, 3 are currently alive; 1 has documented disease. Moderate to severe toxicity was seen in 14 patients (70%). There was one possible treatment-related death from cardiomyopathy. UPSC, despite its histologic and clinical similarities to ovarian carcinoma, was relatively resistant to PAC chemotherapy in this mixed group of patients.

Detection of endometrial antibodies using an indirect immunofluorescence method along with a well-established human endometrial carcinoma cell line was evaluated and compared with CA-125 for detecting endometriosis. Two hundred two patient sera from the infertility, gynecological, and gynecological oncology services were evaluated. The sensitivity for antibody testing was 83.1% with a specificity of 78.8%, in contrast to a sensitivity of 27.3% and a specificity of 82.6% for CA-125. These preliminary findings offer promise that antibody detection methods may be a useful adjunct in the diagnosis of endometriosis.

Thirty-eight patients with irregular perimenopausal hemorrhage in whom carcinoma of the endometrium had been diagnosed by fractional curettage were included in the study. In all patients, the concentration of CA-125 tumor marker was determined preoperatively. Findings were compared to the depth of penetration of stage I adenocarcinoma into the endometrium. A statistically significantly higher CA-125 value was recorded when the tumor had penetrated more than one-third of the uterine wall. This method could be successfully combined with other techniques in therapy planning.

Serum levels of carcinoembryonic antigen (CEA), CA 125 and CA 15-3 were measured in 47 patients with endometrial cancer and 20 with endometrial hyperplasia. Before treatment elevated serum levels of CEA, CA 125 and CA 15-3 were found in 14, 43 and 32% of cancer patients, respectively. In the 20 patients with endometrial hyperplasia, CEA and CA 15-3 values were normal, while elevated CA-125 titers were detected in 1 case. There was an increasing incidence of abnormal levels of all markers in relation to a higher tumor stage (stage I: 36%; II: 66%; III: 100%). The percentage of positive marker values increased in case of deep myometrial infiltration (greater than M1) and/or poorer tumor differentiation (greater than G1). However, only percent increase in CA 15-3 positivity was significantly higher in more infiltrating (greater than M1, 7 vs. 65%, p less than 0.01) and less differentiated (greater than G1, 0 vs. 47%, p = 0.01) tumors. These findings suggest that CA 15-3 is in some way associated with the prognostic factors of the disease. All patients except 2 with no evidence of disease after surgery had normal serum marker values. Moreover, CA 125 and CA 15-3 levels reflected the clinical course of the disease during chemotherapy and seemed to be useful for monitoring response to treatment.

Serial serum CA-125 levels were measured in fifteen patients with recurrent or advanced endometrial carcinoma during treatment with chemo- or hormonal therapy. All patients had measurable disease by physical examination, chest X-ray or CT scan. Serum CA-125 levels were invariably elevated, and generally reflected, response to therapy in all patients with intraperitoneal or pulmonary metastases. Levels were normal in two of three patients with isolated vaginal metastases prior to and following response to progesterone.

Persistent or recurrent peritoneal carcinomatosis (PC) documented at second-look surgery has proved relatively refractory to second-line therapy. The majority of these tumors do not respond to cisplatin based chemotherapy. Because of the relatively high response rate we observed with systemically administered mitomycin C plus 5-fluorouracil, we initiated a trial of intraperitoneal (IP) mitomycin C (10 mg/m2 in 2 L dialysate fluid every 4 weeks) in 14 patients with refractory PC secondary to gynecologic malignancies. All but one patient had PC secondary to ovarian cancer documented at second-look cytoreductive surgery following intense cisplatin based drug therapy. One patient had endometrial cancer and had been treated previously with radiation. In all, 49 courses of intraperitoneal mitomycin C were administered to 14 patients. Systemic toxicity was minimal, except for mild thrombocytopenia that occurred in four patients. However, abdominal pain due to chemical peritonitis was cumulative and dose limiting after three to five courses of therapy. Of the seven patients with measurable disease (positive serum CA-125 or intraperitoneal cytology), six had normalization of at least one of these two parameters. Eight of the 14 patients remain alive without clinical evidence of disease with a median follow-up duration of 10 months. We conclude that IP mitomycin C is a well-tolerated and potentially effective treatment modality in patients with limited PC following second-look surgical debulking for gynecologic malignancy.

Using human cultured cell lines or lymphocytes, two kinds of murine- and one human-monoclonal antibodies were produced, respectively and their clinical usefulness were investigated, and the possibility of galactosyl-transferase as a new tumor maker was also discussed. (1) A murine monoclonal antibody MSN-1, which was raised against human endometrial cancer cell line and recognized blood type sugar chain Leb, reacted with about 85% of endometrial cancer tissues, indicating that useful clinical information may be obtained by applying MSN-1 to immunohistochemistry and flow cytometry. (2) A new assay system using two murine monoclonal antibodies MA54 and MA61, which were raised against human lung cancer cell line and reacted with mucin sugar residues, revealed 76% positive rate in ovarian cancer patients, especially 82% in mucinous cystadenocarcinoma, indicating the clinical effectiveness as a new tumor maker compensating for the drawbacks of CA-125. (3) Galactosyl-transferase isozyme GT-2 was analyzed by the assay system using a newly produced monoclonal antibody. GT-2 was positive in 74% of ovarian cancers, especially in 89% of meso-nephroid cancer, indicating that GT-2 could be a useful tumor maker in ovarian tumors. (4) Human monoclonal antibody, which recognized "type 1 sugar chain" or iso-paragloboside, reacted about one half of endometrial cancer tissues. The production of human monoclonal antibody may contribute to the cancer imaging and the missile therapy.

In order to examine the production of marker proteins, a reproducible method has been established for culturing purified epithelial cells from normal and malignant endometrium. We have examined the differential expression of secretory proteins using immunohistochemistry in frozen tissue sections, immunocytochemistry in cell cultures derived from the same specimens and protein assays on the culture supernatants. Placental protein 14 (PP14) was produced by normal premenopausal epithelium but not by the post-menopausal or malignant endometrial epithelium. In contrast, placental alkaline phosphatase (PLAP) was produced by endometrial cancers and the endometrial adenocarcinoma-derived cell line Ishikawa, but not by the normal endometrial epithelium. Other markers such as CA-125, which was produced by both normal and malignant endometrium but not by the cell line, and human chorionic gonadotrophin (beta-hCG), which was produced by Ishikawa cells but not by any of the fresh tissues, were less cancer specific. Placental alkaline phosphatase is a direct product of endometrial cancers that can be readily assayed in serum using this two-site assay to test its clinical usefulness in monitoring patients at risk for endometrial cancer.

We examined the method of diagnosis for a group of women who developed recurrent endometrial carcinoma after being rendered clinically disease-free by primary therapy. We then used this information to develop a follow-up protocol that maximizes the chances for detecting recurrence while minimizing surveillance costs. In brief, we evaluated all women with clinical stage I endometrial carcinoma who were treated with curative intent during a 7-year period. Medical records were examined to identify patients who had tumor recurrence diagnosed during follow-up in our clinic. Clinical presentation, time to diagnosis, method of diagnosis, and subsequent outcome were analyzed. This information was used to design a surveillance protocol for further clinical testing. Ninety-six percent of 412 women treated between 1985 and 1992 were clinically disease-free after primary surgery with or without adjuvant treatment. Median follow-up is 64 months. Overall, 44 patients (11%) developed recurrent cancer after a median interval of 14.8 months. Complete follow-up data were available for the 39 patients who had their recurrence diagnosed in our clinic. The cumulative percentages of diagnosed recurrences were 51, 82, and 95% at 12, 24, and 36 months, respectively. Sixteen women (41%) had symptoms that led to the identification of recurrent disease. Recurrences in the 23 asymptomatic women (59%) were diagnosed by physical examination in 13, chest radiograph in 1, serum CA-125 level in 6, vaginal cytology in 1, and computed tomography in 2. Only 1 patient with a grade 1 adenocarcinoma had treatment failure. At the time of analysis, 30 patients with recurrent cancer had died of disease, 6 were alive with disease, and 3 were free of disease. A surveillance scheme consisting of an examination, vaginal cytology, and serum CA-125, combined with immediate evaluation of symptomatic women, could be expected to identify 95% of recurrences. Such an approach, performed at 6- to 12-month intervals for 3 years, could be limited to patients with grade 2-3 adenocarcinomas or variant cell types. However, given the high failure rate of salvage therapy, the prompt detection of recurrence may not convey a survival advantage.

CA-125, a high-molecular-weight glycoprotein antigen, has been identified as a possible marker for endometriosis, with discrepant results. CA-72, another glycoprotein antigen, is expressed by a variety of adenocarcinomas, including endometrial carcinoma. This controlled, prospective study evaluated serum CA-125 and CA-72 levels in 35 consecutive patients with endometriosis of varying stages and in patients without endometriosis. Serum CA-125 and CA-72 were measured with immunoradiologic methods prior to diagnostic laparoscopy for infertility evaluation. Endometriosis, scored by American Fertility Society guidelines, was identified in 19 patients, and 16 patients had normal pelvic findings. CA-125 and CA-72 levels were not different between patients with no pelvic disease (controls) and women with stage I-IV endometriosis. The positive predictive value of CA-125 was 0%; the negative predictive value was 47%. The positive predictive value of CA-72 was 5%; the negative predictive value was 53%. CA-72 and CA-125 are not helpful in the routine workup of the infertile woman to determine the likelihood that she has pelvic endometriosis.
