- Abstract
Pre-menopausal tamoxifen treatment causes hyperoestrogen production and ovarian cyst formation. Two pre-menopausal breast cancer patients who were treated with tamoxifen developed both permanent supraphysiological oestrogen concentration and ovarian cysts. Serum oestrogen decreased to post-menopausal concentrations and ovarian cysts completely resolved during and following simultaneous treatment with tamoxifen and gonadotrophin-releasing hormone agonist (GnRHa). In pre-menopausal breast cancer patients, GnRHa may prevent possible side-effects of tamoxifen, such as ovarian cysts and supraphysiological oestrogen production. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Cytokeratins are constituents of the intermediate filaments of epithelial cells which are expressed in various combinations depending on the epithelial type and the degree of differentiation. Using the reverse transcriptase-polymerase chain reaction technique (RT-PCR) we recently demonstrated that: (1) Cytokertin 20-the most recent discovered cytokeratin-is expressed in endometrial carcinoma tumors but not in the endometrium of patients with benign diseases, and (2) CK-20 is not expressed in blood cells. The aim of this study is to examine whether CK-20 expression in blood can be used as a biomarker for the detection of the dissemination of malignant cells in patients treated for endometrial carcinoma., Methods: In the present study, we have used RT-PCR to determine the expression of CK-20 in the peripheral blood of the following groups: (1) preop new diagnosed patients (n = 20), (2) patients with no clinical evidence of disease following completion of definitive treatment (n = 33; 17 at low risk; 16 at high risk), (3) patients with recurrent disease (n = 6), and (4) a control group of healthy subjects (n = 16). RNA was extracted from cell pellets and analysed by RT-PCR using primers for CK-20., Results: Of the 20 patients of the first group 7 (35%) were CK-20 positive. Of the 33 patients of the second group 17 (51%) were CK-20 positive. Subdivision of this group showed that 9 of 17 (53%) were positive in the low-risk subgroup, and 8 of 16 (50%) were positive in the high-risk subgroup. All 6 patients with recurrent disease were positive, and all subjects in the control group were negative., Conclusion: These results indicate that RT-PCR of CK-20, because of its high sensitivity, is a potential biomarker for detecting metastasis in blood samples of patients with endometrial carcinoma., (Copyright 2000 Academic Press.)

- Abstract
Background: Cytokeratins are constituents of the intermediate filaments (IFs) of epithelial cells which are expressed in various combinations, depending on the type of epithelium and degree of differentiation. We have reported (R. Zemer, A. Fishman, J. Bernheim, S. Zimlichman, O. Markowitz, M. Altaras, and A. Klein, Gynecol Oncol 70:410-413, 1998) on the determination of cytokeratin-20 (CK-20) by reverse transcription polymerase chain reaction (RT-PCR) in the detection of endometrial cancer cells as a potential biomarker. In that study, we also found that by using immunocytochemistry, most carcinomas were found to be negative for CK-20. The sensitivity and specificity rates obtained by using the RT-PCR method were 94.4 and 91%, respectively., Objective: The aim of this study is to investigate the feasibility and potential of the specific mRNA marker, CK-20, to detect endometrial cancer cells-micrometastases (MMs)-by RT-PCR in lymph node (LN) samplings of patients undergoing hysterectomy for endometrial carcinoma., Method: We used the RT-PCR method to determine the expression of CK-20 in the LNs of 20 patients [study group (SG)] who were being surgically staged and treated for endometrial carcinoma. The specificity of the mRNA CK-20 marker was examined in LNs obtained from five healthy patients [control group (CG)] who underwent abdominal hysterectomy and bilateral salpingo-oopherectomy for benign gynecologic conditions. The LNs obtained from the SG and CG patients were prepared together before mRNA extraction. RNA of the various cell pellets was extracted and RT-PCR was performed with CK-20 primers. RT-PCR products were analyzed by agarose gel electrophoresis and ethidium bromide staining against PCR size markers. Specificity of the RT-PCR products was examined by Southern blotting., Results: Histopathologic examinations demonstrated the presence of metastases in two (10%) SG patients. These patients were also CK-20 positive. Of the remaining 18 patients with negative histopathologic results, 6 (33%) were CK-20 positive and 12 (67%) were negative. All the CG patients were CK-20 negative (specificity, 100%)., Conclusions: The results obtained in this study suggest that RT-PCR of CK-20 is more sensitive than traditional histopathologic methods in the diagnosis of MMs in LNs of patients with endometrial cancer. Thus, due to the aforementioned characteristics of CK-20, it may be considered a powerful biomarker in the detection of MMs in LNs of patients with endometrial cancer., (Copyright 2000 Academic Press.)

- Abstract
To assess whether a higher cumulative tamoxifen dose is associated with increased incidence of various types of endometrial pathologies, we compared cumulative dose of tamoxifen treatment as well as demographic characteristics, risk factors for endometrial cancer, transvaginal ultrasonographic endometrial thickness, and various treatments for the primary breast cancer between 159 postmenopausal breast cancer tamoxifen-treated patients without endometrial pathologies (group I) and 67 similar patients with endometrial pathologies (group II). A similar comparison was made between group I patients and similar patients with proliferative endometrium (group IIa), with endometrial hyperplasia (group IIb), with endometrial polyps (group IIc), and with endometrial cancer (group IId). Overall cumulative tamoxifen dose was significantly higher in group II as compared to group I (27.4+/-33.4 and 17.4+/-20.2, respectively; P<0.0252). Transvaginal ultrasonographic endometrial thickness was significantly higher in group II than in group I patients (16.3+/-11.3 mm and 12.1+/-6.3 mm, respectively; P<0.0147). The frequency of diabetes mellitus, of previous postmenopausal bleeding, and of previous exposure to hormone replacement therapy was significantly higher in group II than in group I patients (P<0.001, P<0.0001 and P<0.001, respectively). There were no significant differences in all parameters tested between group I, group IIa, group IIb, group IIc, and group IId. However, there was an obvious trend for higher cumulative tamoxifen dose in patients with benign endometrial pathologies as compared to those without endometrial pathologies or to those with endometrial cancer (Group I = 17.4+/-20.2 g, group IIa = 22.5+/-18.5 g, group IIb = 28.1+/-20.3 g, group IIc = 31.4+/-42.7 g and group IId = 10.4+/-12.6 g). Endometrial pathologies, except for endometrial cancer, are associated with a high cumulative dose of tamoxifen in postmenopausal breast cancer patients.

- Abstract
Aim: Tamoxifen is the antihormonal treatment of choice for premenopausal breast cancer patients with advanced breast disease. Its premenopausal administration has been shown to induce supraphysiological 17beta-estradiol serum levels and to be associated with the presence of persistent, bilateral functional ovarian cysts. However, these abnormalities have not yet been compared to controls. In this study we evaluated the possibility that the above hormonal and/or ovarian abnormalities are more frequent among premenopausal breast cancer patients treated with tamoxifen than among similar nontreated patients, and thus they may be attributed to tamoxifen effect., Methods: We evaluated serum hormone levels of 17beta-estradiol, follicular-stimulating hormone, luteinizing hormone, and progesterone, the presence of ovarian cysts, and various demographic and clinical characteristics in 20 premenopausal breast cancer patients treated with tamoxifen (study group) and compared them to those observed in 12 similar nontreated patients (control group)., Results: Ovarian cysts were found in 80% of the study patients and only in 8.3% of the control patients (P = 0.001). The incidence of oligomenorrhea was nearly significantly higher in the study than in the control group (50 and 16.7%, respectively; P = 0.0651). Various serum hormone levels tested were not found to be significantly different between the two groups, except for 17beta-estradiol serum levels as detected on days 14 and 21 of the menstrual cycle, which were significantly higher among the study than in the control patients. (Day 14 serum estradiol: 757.7 +/- 372.0 pg/mL versus 206.5 +/- 275.0 pg/mL, P = 0.0012. Day 21 serum estradiol: 300.0 +/- 134.5 pg/mL versus 96.5 +/- 71.5 pg/mL, P = 0.0008.), Conclusions: Tamoxifen treatment increases the incidence of ovarian cysts and the significantly higher 17beta-estradiol serum levels in premenopausal breast cancer patients., (Copyright 1999 Academic Press.)

- Abstract
We tested the hypothesis that loss of replication control of DNA loci associated with human centromeres affects the main centromere function, namely, ensuring proper sister chromatid separation and accurate chromosomal segregation during cell division. Applying one-color fluorescence in situ hybridization (FISH) to interphase nuclei, we studied the replication patterns of homologous DNA loci associated with human centromeres (alpha-satellite sequences) of chromosome pairs 10, 11, 17, and X in PHA-stimulated lymphocytes of female cancer patients with a familial predisposition to malignancy and normal, healthy women. Concomitantly, we measured the rates of aneuploidy for these chromosomes in the same cells. To elucidate the replication patterns of the various centromeric loci, we analyzed the replication-dependent configuration signals obtained following FISH with four chromosome-specific alpha-satellite probes. Our data showed an association between replication timing of alpha-satellite sequences and centromeric function. Chromosome pairs whose homologous alpha-satellite loci replicated highly synchronously revealed low rates of aneuploidy, whereas chromosome pairs with a slightly asynchronous replication pattern (i.e., short intervals between early- and late-replicating loci) revealed intermediate rates of aneuploidy, and chromosome pairs exhibiting asynchrony with long-time intervals between early- and late-replicating loci showed the highest rate of aneuploidy.

- Abstract
Assessment of receptor levels in tamoxifen-exposed endometrial pathologies may indicate endometrial cells potential for interaction with tamoxifen. To assess this assumption, we analyzed estrogen receptor (ER) and progesterone receptor (PR) expression by an immunohistochemical technique in endometrial specimens with benign hyperplasia, benign polyps, and carcinoma obtained from postmenopausal breast cancer patients treated with tamoxifen (study group) and from age-matched healthy postmenopausal women treated with estrogen replacement therapy (control group I) and not treated with estrogen replacement therapy (control group II). Overall gland and stromal ER expression of benign endometrial hyperplasia and of benign endometrial polyps was significantly higher in control groups I and II than that obtained from the study group (endometrial hyperplasia: P = 0.0274 and 0.00093, respectively, and P = 0.00003 and 0.00001, respectively; benign endometrial polyps: P = 0.02889 and 0.00596, respectively; and P = 0.00228 and 0.00005, respectively), while there were no differences between the two control groups. Overall gland and stromal PR expression was nearly similar in all the three groups (P = NS). There was no correlation between the length of tamoxifen treatment and the presence of ER and PR in various endometrial pathologies in the tamoxifen-treated patients. The significantly lower ER expression in most benign endometrial pathologies obtained from postmenopausal tamoxifen treated patients may further support the weak estrogen-like effect of tamoxifen on the endometrium in the menopause.

- Abstract
Postmenopausal breast cancer patients who were treated with tamoxifen and progestogens showed a uniform decidual reaction of the endometrium. It is well established that progestogens antagonize the estrogen effect on the endometrium by reducing its receptors in the endometrium. To assess in vivo such a possible effect of progestogens on endometrium primarily exposed to tamoxifen, we analyzed estrogen and progesterone receptors (ER, PR) on endometrial specimens showing decidualization from nine postmenopausal breast cancer patients on tamoxifen and progestogen treatment and on endometrial polyps with areas of decidualization from two other similar patients. ER was weakly detected in the endometrial glands of four (36.4%) patients and in the endometrial stroma of one (9.1%) patient. PR was detected in the endometrial gland of only one (9.1%) patient. No PR was detected in the endometrial stroma. There was no correlation between the length of tamoxifen treatment, the tamoxifen dosage, or the length of progestogen treatment and the ER or PR content, although progestogens were administered for more than 3 consecutive months in all patients. This relatively very low ER and PR content may be attributed to the antagonistic effect of progestogens on the "priming" estrogen-like effect of tamoxifen on the endometrium.

- Abstract
A prospective study was performed to assess the efficacy of sonohysterography (SHG) in identifying endometrial pathologies among asymptomatic, postmenopausal breast cancer patients treated with tamoxifen. In this study the uterine cavity of 68 such patients with endometrial thickness of > or = 8 mm was prospectively evaluated by SHG. Forty-six (67.6%) patients in whom SHG did not identify any findings in the uterine cavity (negative group) were followed by diagnostic hysteroscopy. Another 22 (32.4%) who were identified by SHG to have abnormal endometrial findings, such as an echogenic or polypoid mass (positive group), were followed by operative hysteroscopy and by postoperative SHG. In the positive group the basal transvaginal sonogram revealed an endometrial echogenic mass in only 10 (45.5%). In the remaining 12 (54.5%) patients, the transvaginal sonogram identified only thick endometrium. In these latter 12 patients, histological assessment confirmed endometrial polyps in 8 (66.7%) and fibroid in 1 (8.3%). Four (18.2%) patients in the positive group had no histological endometrial pathology. Two (50%) of them had a uterine septum as diagnosed during hysteroscopy, in one (25%) operative hysteroscopy failed to resect the endometrial polyp, and in another (25%) there was a false-positive SHG diagnosis. Overall, SHG accurately diagnosed endometrial and/or other intrauterine pathology in 95.5% of these patients. In the 46 patients with "negative" basal SHG features, diagnostic hysteroscopy confirmed this diagnosis. Thus, there was no SHG false-negative diagnosis. Comparing the results of the basal SHG with those of operative hysteroscopy and/or the histopathological findings in the positive group, the sensitivity of SHG was 1.0, the specificity 0.0, positive predictive value 95.5%, and negative predictive value 0.0. It is suggested that SHG is a useful diagnostic tool for the assessment of specific endometrial pathologies in asymptomatic postmenopausal breast cancer patients treated with tamoxifen who were diagnosed by transvaginal sonography to have thick endometrium.

- Abstract
Background: Postmenopausal breast cancer patients treated with tamoxifen have been found to have a high incidence of ovarian tumors. Transvaginal ultrasonography is an accurate and reliable method for measuring ovarian size. The purpose of this study was to establish normal values for basal ovarian volume in postmenopausal tamoxifen-treated patients and compare them with those established for healthy, postmenopausal women in the same population with no exposure to hormone treatment., Methods: In a prospective open pilot study, the ovaries of 65 postmenopausal breast cancer patients treated for at least 6 months with tamoxifen were measured by transvaginal ultrasonography. From the same population, 311 healthy postmenopausal women with no exposure to hormone therapy were examined and served as controls. After matching for menopausal age, ovarian volume was compared between groups., Results: Mean ovarian volume of postmenopausal tamoxifen-treated patients was persistently low through the menopause, whereas the mean ovarian volume of the controls was large, gradually decreasing up to the 10th menopausal year (8.6 +/- 2.3 and 2.8 +/- 2.1 cm3, respectively). Mean ovarian volume of the tamoxifen-treated patients was significantly lower than that of the controls during the initial menopausal years., Conclusions: An ovarian volume that is considered within normal range for a specific menopausal age in a healthy postmenopausal woman is abnormal for a postmenopausal tamoxifen-treated patient.

- Abstract
Various endometrial lesions were more frequent among asymptomatic postmenopausal breast cancer patients who were treated with tamoxifen for > 48 consecutive months (30.8%) when compared with similar patients who were treated for 6-24 months or for 25-48 months (20.8% and 12.5%, respectively). However, this difference was not statistically significant. There were also no significant differences in the frequency of the various endometrial lesions between these three groups, although endometrial polyps were more frequently found among those treated for > 48 months. Overall, 20.7% of the 164 tamoxifen-treated patients in the study had an endometrial pathology. It can be concluded that there is a slight tendency among those postmenopausal patients who have been treated for > 48 consecutive months to have a higher frequency of endometrial lesions.

- Abstract
From September 1, 1989, to November 30, 1994, 175 menopausal breast cancer patients treated with tamoxifen were followed at the authors' institutions. During this period. 16 (9.1%) underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy, for various indications. Of these, 10 (62.5%) had either uni- or bilateral ovarian tumors. The analysis of surgical findings showed an incidence of 5.7% (10/175) ovarian tumors among all the patients. In 2 (20%), the ovarian masses displayed enlargement over a relatively short period while on treatment. In 5 (50%) patients, the findings were bilateral. All tumors were detectable by ultrasonography, except four serous cystadenomas found in 3 women. The mean duration of tamoxifen treatment was 36.6 +/- 24.9 (range 9-86) months. The rate of 5.7% for ovarian tumors, in this selected group of patients, is four to five times higher than that reported for similar pathologic conditions detected by general screening with ultrasonographic scans among nonselected, asymptomatic, and untreated postmenopausal women. Two possibilities should be considered in the development of ovarian tumors coinciding with tamoxifen treatment; (1) women with breast malignancy are prone to develop benign or malignant ovarian tumors in relation to genetic factors, regardless of tamoxifen treatment; and (2) tamoxifen may stimulate enlargement of such tumors and may even cause them.

- Abstract
In order to assess endometrial reaction to the combined treatment of tamoxifen and progestogens in asymptomatic postmenopausal breast cancer patients, we evaluated all such patients by vaginal ultrasonography and by histological examination of endometrial samplings. All patients were initially treated with tamoxifen, and progestogens were then added when metastases became evident. Of 12 patients included in the study, eight (66.66%) showed evidence of strong endometrial stromal decidualization, while three (25%) had decidual reactions in endometrial polyps. Overall, 11 (91.66%) of the patients had decidual reactions, and all were treated with progestogens for > or = 3 consecutive months. One patient, treated with progestogens for 1 months, had an inactive endometrium. All but three had thickened endometria (> 10 mm) on ultrasonographic evaluation. These data show that postmenopausal breast cancer patients who received progestogens for < or = 3 months, and who concomitantly took tamoxifen, had a uniform decidual reaction in all uteri.

- Abstract
Between September 1, 1989 and October 31, 1994, 173 postmenopausal breast cancer women on tamoxifen treatment were followed up in the authors' institutions. During this period, 14 (8.1%) underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy for various indications. Eight (57.1%) were found to have adenomyosis, of whom one had a large fundal adenomyotic lump and the other seven patients had two to four small microscopic foci of adenomyosis. In this study, the rate of adenomyosis described among those postmenopausal breast cancer patients treated with tamoxifen is nearly three to four times higher than the rate reported in the literature for pre- and postmenopausal women. There is no previous reported increased incidence of adenomyosis in postmenopausal breast cancer patients treated with tamoxifen. Thus, it is suggested that the prolonged and unopposed estrogen-like stimulation by tamoxifen may play a causal role rather than be a casual factor in the development of this pathologic entity.

- Abstract
Two patients, who developed anaphylaxis to cisplatin, are described. This phenomenon was preceded by mild allergic symptoms, which were overlooked, in previous treatment courses. Intradermal skin tests were both sensitive and specific in the diagnosis of cisplatin allergy. Pretreatment with antihistamines and corticosteroids was ineffective in preventing recurrent anaphylaxis. Thus, a trial of desensitization is mandatory among those patients whose disease responds to the administration of this agent.

- Abstract
Endometrial thickness, as evaluated by vaginal ultrasonography, and endometrial histologic findings, as well as demographic characteristics, health habits, and risk factors for endometrial cancer, were compared between 93 asymptomatic postmenopausal breast cancer patients who had been on tamoxifen treatment and 20 patients who had not. The mean ultrasonographic endometrial thickness in the women on tamoxifen treatment was 13.1 +/- 10.4 mm, which was significantly thicker than the 4.0 +/- 3.2 mm found in the nontreated women (P = 0.001). The frequency of endometrial pathological findings was remarkably high (35.5%) among the tamoxifen-treated patients, compared with nontreated patients (20.0%), with a P value of 0.058 and an odd ratio of 4.6. Thus, it is suggested that the remarkably high prevalence of pathological endometrial changes was due to the continuous and unopposed exposure of the endometrium to tamoxifen.

- Abstract
Objective: The aim of this study was twofold: firstly to evaluate and compare the diagnostic precision of the microhysteroscopy (MH) and endometrial biopsy in a group of menopausal women in whom D&C had failed to obtain an adequate endometrial sample, and secondly to quantitate the value of a hysteroscopy in determining endometrial sampling in these patients., Methods: A Hamou type II CO2 microhysteroscope (MH) was used to evaluate the endocervical canal and the uterine cavity, followed by endometrial sampling., Results: Thirty-nine women were assessed using MH and endometrial biopsy. Histopathology results were available for diagnosis in 29 of them (74.3%). In the remaining ten patients, the MH diagnosis was atrophic endometrium. Biopsy results corroborated with MH in 86.2% (25/29) of the patients with tissue samples. The analysis (r) of this concordance rate was statistically significant (r = 0.96). Sample results for patients with MH determined pathological and normal endometrium corroborated in 83% and 91%, respectively, inclusive of three cases of endometrial adenocarcinoma. The sensitivity, specificity and predictive values for MH alone were 93.7%, 76.9% and 83.3%, respectively., Conclusions: These significant results are indicative that this simplified endoscopic method surpasses all blind hospital or office endometrial sampling methods. Therefore, we suggest that MH and endometrial sampling should be the initial assessment tool for any type of indication requiring endometrial and uterine cavity assessment.

- Abstract
Objective: To evaluate whether risk factors, other than tamoxifen, can be identified for the development of endometrial pathologies in postmenopausal breast cancer patients treated with tamoxifen., Design: A cross-sectional study., Setting: Department of Obstetrics and Gynaecology and Oncology Clinic, Sapir Medical Center, Kfar Saba, Israel., Subjects: 77 asymptomatic postmenopausal women, treated with tamoxifen for breast cancer. Of these, 55 had no endometrial tissue and 22 had endometrial tissue obtained by biopsy., Main Outcome Measures: Demographic characteristics, health habits, risk factors, vaginal ultrasonographic evaluations of endometrial thickness and texture, and histologic evaluations of endometrial biopsies., Results: Overall, there was a high rate (29%) of endometrial pathological change among the 77 asymptomatic postmenopausal women. There were no significant statistical differences in the features tested between the two groups., Conclusion: It is impossible to predict which postmenopausal women will develop pathological endometrial changes after treatment with tamoxifen and thus a routine periodic endometrial sampling-follow up is suggested for all postmenopausal women being treated with this agent.

- Abstract
We present the first case of heterologous mixed mesodermal tumor that developed 9 years following tamoxifen therapy in a climacteric woman with no previous pelvic irradiation and was initially treated by total abdominal hysterectomy and bilateral salpingo-oophorectomy. She continued tamoxifen therapy for 2 years, following the initial treatment, until the diagnosis of a recurrent tumor by laparotomy. The patient died of the disease 5 months subsequent to the second surgery. The association of prolonged unopposed estrogenic stimulation, with tamoxifen as a possible etiologic factor in the development of endometrial sarcomas, is discussed.

- Abstract
A 28-year-old woman was evaluated for late onset secondary amenorrhea, progressive hirsutism and an elevated serum testosterone concentration. Her serum cortisol, androstenedione, dehydroepiandrosterone sulfate and 17-hydroxyprogesterone levels were normal. Bilateral ovarian and adrenal vein catheterization demonstrated mild elevated testosterone and androstenedione levels in the right ovarian vein. Fifteen minutes after administering the intravenous injection of 5,000 IU human chorionic gonadotropin, there was a six and a half to sevenfold increase in the level of these two hormones in the right ovarian vein with no significant change in hormone levels from other sources. Based on the ovarian peripheral vein gradients obtained during venography following ovarian stimulation, the diagnosis of right ovarian hyperthecosis was made. This diagnosis could not have been reached without the combination of selective ovarian vein catheterization and ovarian stimulation. We recommend that this combined test, which may provide additional information on the source of the androgens in women with hyperandrogens, be performed in selected cases, when a virilizing tumor is suspected.

- Abstract
Preoperative quantitative assessment of pelvic fluid is an important diagnostic tool in clinical decision making. In this study, we used high-frequency transvaginal ultrasonography in 10 healthy women to assess both the correlation between various amounts of fluid installed in the cul-de-sac and ultrasonic imaging and to determine whether correct estimation of fluid volume can be reached. No fluid could be ultrasonically detected when the volume was less than 35 to 40 ml. Between 35 and 100 ml there was a clear image of accumulated fluid in the cul-de-sac with good correlation between volume and image, whereas with larger amounts no clear correlation between the amount of fluid introduced and size of fluid area visualized by ultrasonography was possible. Transvaginal ultrasonography may enable quantitative evaluation of certain volumes of pelvic fluid, although amounts less than 35 ml cannot be visualized.

- Abstract
From January 1, 1984 to April 30, 1990, 38 patients were surgically found to have an intraabdominal disease resembling epithelial ovarian cancer. This diagnosis was confirmed in 31 patients; the remaining 7 met the criteria of primary peritoneal papillary serous carcinoma. Five of these were diagnosed retrospectively and two during surgery. The mean age at diagnosis was 61.2 years. Tumor histology revealed papillary serous carcinoma in six and mixed (papillary serous and papillary clear cell carcinoma) in one patient. Optimal debulking was achieved in three of seven cases (42.8%). Cisplatin-based combination chemotherapy was administered to all in the study group. Complete response was obtained in four patients, with one surviving for 76 months. The median survival in these patients was 34.5 months (range 6-76 months). Currently, three patients with complete response are alive with clinically undetectable disease. CA-125 assays were available in three cases and blood levels corroborated the clinically determined status of the disease. Tumor steroid hormone receptor status was determined in one case and revealed low levels of estrogen and progesterone receptors. To the best of our knowledge, the usefulness of CA-125 in the diagnosis, management, follow-up, and determination of tumor steroid hormone receptor status, mixed papillary serous and clear cell subtype histological patterns for primary peritoneal papillary serous carcinoma are first described in this report. It seems that this neoplasm may be treated and followed up as in epithelial ovarian cancer, obtaining long-term survival; however, the biologic behavior and management problems of this relatively new entity deserve further clinical experience.

- Abstract
We report a technique of cone cerclage and the results and outcome in 17 patients who required a diagnostic cone biopsy in pregnancy. The mean age of the patients was 30.6 years (range 21-41). The mean gestational age was 18.8 weeks (range 10-32) at the time of the procedure. There were no major complications and hemorrhage was not a significant problem. There were no second-trimester abortions. Two patients required beta-sympathomimetics to suppress uterine activity for longer than 24 hours after the procedure. Six patients had invasive carcinoma, nine had cervical intraepithelial neoplasia (CIN) III, and two had CIN II. In 14 cases, the endocervical and ectocervical margins were negative; two patients with CIN and one with multifocal microinvasion had positive margins. Cone cerclage is a safe and easy method for performing diagnostic cervical conization during pregnancy.

Two cases of primary paraovarian-origin serous cystadenocarcinoma, one invasive and one of low malignant potential, are presented. Both were diagnosed in postmenopausal women and were initially treated surgically. As of this writing, both women have survived 48 months past their initial diagnosis and have no clinically detectable disease. Clinical aspects and management problems of this fairly recently identified and rare entity are discussed and the literature on primary paraovarian malignant epithelial tumors is reviewed.

- Abstract
Two cases of endometrial sarcoma that developed many years after exposure to unopposed exogenous and endogenous estrogens, with no previous pelvic irradiation, are described. The literature is reviewed and the possible effect of prolonged unopposed estrogen stimulation is suggested as an etiologic factor in such extremely rare conditions. These cases add additional support to the assumption that prolonged and excessive endogenous or exogenous unopposed estrogen stimulation of the uterus may increase the risk of endometrial sarcoma.

- Abstract
The value of cancer antigen-125 (CA-125) as a tumor marker for malignant germ cell tumors (MGCT) of the ovary was investigated and compared with the other recognized tumor markers (human chorionic gonadotrophin (hCG), alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA) and lactate dehydrogenase (LDH) isoenzymes. In the 10 months following June 1984, 4 new cases with MGCT and 1 patient with active disease on treatment were evaluated. In all cases prior to planned surgery the levels of CA-125 were significantly elevated. The serum values ranged from 154 to 617 U/ml (normal less than 20 U/ml). In 1 case (pure dysgerminoma) CA-125 was the only tumor marker. In 3 patients (2 mixed germ cell tumors and 1 immature teratoma) serum LDH (LD 1, 2, and 3) was elevated, and AFP was elevated in 1 of these. In the fifth case (mixed germ cell tumor), on treatment, serum AFP was used to monitor the disease. Four patients underwent cytoreductive surgery followed by combination chemotherapy. The changes in the serum levels of CA-125 paralleled those of the other tumor markers while on therapy. In our experience CA-125 is an invaluable indicator of the clinical status of the patient and could be a new tumor marker in patients with MGCT.

- Abstract
From June 1, 1984, to May 31, 1985, 98 cases of epithelial ovarian carcinomas were assessed and followed prospectively using a new murine monoclonal antibody OC 125 which detects the antigen CA 125. Serous tumors comprised 43.7% of cases, mucinous tumors 20.4%, endometrioid tumors 16%, and other epithelial tumors 19.4%. Tumors of low malignant potential and benign epithelial cystadenomas were not included. For this study the upper limit of normal for CA 125 was 20 U/ml. Thirty-six were new cases. In this group the initial CA 125 levels greater than 20 U/ml, greater than 35 U/ml, and greater than 65 U/ml were 97.2, 94.4, and 86.1%, respectively. When mucinous types were excluded the specificity rate did not change significantly. There was no significant difference in initial CA 125 levels between early stages I and II and late stages III and IV. No correlation between tumor bulk and the serum level of antigen was observed. The remaining 62 patients were being followed and in this group 50 were considered to be in remission. Six cases in the remission group had elevated CA 125 levels greater than 20 U/ml and 5 of these developed clinical recurrence. The correlation between the clinical status and concordant fluctuations in the serum levels of CA 125 in all histological types was 87.8 and 93.5% when 10 cases of mucinous tumors were excluded. The contingency coefficient was 0.746. Seven SLOs were performed. All had CA 125 levels less than 20 U/ml and the mean was 6.9 U/ml. Only 1 case was positive with microscopic disease. In our experience CA 125 was invaluable in the management and follow-up of patients with ovarian carcinoma especially for the early detection of recurrent disease and for the monitoring of patients on therapy.

- Abstract
Microhysteroscopy (MH) was used for the assessment of endocervical involvement in patients with endometrial carcinoma. Between 1 July 1984 and 28 February 1985, fifteen cases were seen. Of these, nine patients had had fractional curettage and all were deemed to have endocervical involvement. As a result of the use of MH, five of these stage II cases were down-staged. The remaining four cases had their staging confirmed by MH and directed endocervical curettage. The six patients who had no initial endocervical assessment were found to have Stage I disease, using the MH alone. The MH findings were corroborated and confirmed on histological examination of the surgical specimens. MH should be the initial investigation in patients with suspected endometrial carcinoma and all patients with postmenopausal bleeding.

- Abstract
The effect of medroxyprogesterone acetate (MPA: Depo-Provera, Upjohn) as a contraceptive agent was assessed in 45 patients with non-metastatic gestational trophoblastic disease and compared with 13 patients using hormonal and 26 patients using non-hormonal methods of contraception. In the whole group of 84 patients 18 (21.4%) required chemotherapy. There was no statistically significant difference in the incidence of persistent trophoblastic disease between MPA (9/45) and the oral contraceptive group (2/13) and MPA and the non-hormonal contraceptive groups (7/26).
