Abstract
Exploring whether the positive association between birth weight and breast cancer risk differs by other breast cancer risk factors may help inform speculation about biological mechanism. In these data, high birth weight was associated with breast cancer risk in younger and in more educated women, but was not associated overall.

Abstract
The microscopic phenotype of cervical intraepithelial neoplasia (CIN) reflects a fine balance between factors that promote or reduce CIN development. A shortcoming of the current grading system is its reliance on static morphology and microscopic haematoxylin-eosin features of the epithelium alone. In reality, CIN is a dynamic process, and the epithelium may exhibit differing results over time. Functional biomarkers p16, Ki-67, p53, retinoblastoma protein cytokeratin (CK)14 and CK13, help in the assessment of an individual CIN's lesion's potential for progression and regression. The aggregate information provided by these biomarkers exceeds the value of the classic grading system. Consequently, many more CINs that will either regress or progress can be accurately identified. These findings agree with known molecular interactions between HPV and the host. For accurate interpretation of a CIN, it is essential that these biomarkers be determined quantitatively and separately in the superficial, middle and deep layers of the epithelium. Such geography-specific epithelial evaluations of quantitative biomarkers emphasise the dynamic nature of a particular CIN lesion, thereby changing the art of static morphology grading into dynamic interpretation of the diseased tissue, with a strong prognostic effect.

Abstract
OBJECTIVES Women exposed prenatally to diethylstibestrol (DES) have an excess risk of clear-cell adenocarcinoma of the vagina and cervix, but the effect on the incidence of squamous neoplasia is uncertain. The purpose of the current study was to evaluate the long-term risk of developing high-grade squamous neoplasia of the genital tract among women exposed prenatally to DES. METHODS A cohort comprising 3,899 DES-exposed and 1,374 unexposed daughters was followed for 13 years (1982 1995) for pathology-confirmed diagnoses of high-grade squamous intraepithelial neoplasia (HSIL) of the genital tract. Poisson regression analysis was used to compute relative risks (RR) and 95% confidence intervals (95% CI), adjusting for age, calendar year, and other covariates. RESULTS The RR (95% CI) among DES-exposed versus unexposed, based on 111 cases of high-grade disease, was 2.1 (1.2-3.8). Adjustment for screening history estimated by the number of years since the last Pap smear had little effect. Risk estimates were higher with earlier intrauterine exposure; the RR (95% CI) for exposure within 7 weeks of the last menstrual period was 2.8 (1.4-5.5). Only two cases of invasive squamous cervical cancer occurred in total, precluding separate analysis. CONCLUSIONS The findings support an association between in-utero DES exposure and high-grade squamous neoplasia, although a role for more intensive screening among DES-exposed women in the production of this excess could not be completely ruled out.

Abstract
OBJECTIVE To assess the effects of a red clover-derived isoflavone extract on the Ki-67 proliferative marker of endometrial biopsies in 45-to 50-year-old perimenopausal women. We hypothesized that we would be able to detect a decrease in the Ki-67 proliferative index during the late follicular phase after a 3-month course of approximately 50 mg red clover isoflavones. Isoflavones have been found to have some antiestrogenic effects, and an antiproliferative effect during the perimenopausal period may be especially useful owing to the excessive endometrial proliferation often characteristic of this period. DESIGN In a double-blind, randomized, controlled study, 30 women between the ages of 45 and 50 years consented to an endometrial biopsy before and after a 3-month course of either placebo or active isoflavone extract. The biopsies were timed as close as possible to days 7-11 of the menstrual cycle, and simultaneous measurements of transvaginal endometrial thickness, uterine artery Doppler, hormone profiles, lipids, and bone markers were performed. RESULTS Of 30 women, 2 did not return for a second biopsy, and a third had an unsuccessful second biopsy. Four subjects were excluded from the Intention to Treat analysis because they did not have a menstrual bleed within the time frame of the study (3 subjects) or were tested on day 13 instead of between days 7 and 11 of the cycle (1 subject). There was no change in the Ki-67 proliferation index after treatment in either group. Eight subjects in the placebo group and eight in the P-07 group had proliferative endometrial biopsies that were synchronized with estradiol levels at baseline and post-treatment, and analysis of these subjects revealed no detectable change in the relationship between estradiol levels and Ki-67 with treatment in either group. There was no change in fasting lipids, bone markers, uterine Doppler resistance, or pulsatility index. CONCLUSION In this small pilot study, we did not find, using immunohistochemical quantification of the Ki-67 antigen, that red clover isoflavones had an antiproliferative effect in the endometrium. Small sample size, examination of a relatively short interval in the menstrual cycle, and isoflavone formulation may have contributed to our lack of findings; however, we believe that the issue of isoflavones and their possible antiproliferative effect is deserving of further study. A simpler physiological model with less hormonal variability, such as healthy, recently menopausal women on predetermined doses of estrogen, may prove to be more informative.

Abstract
BACKGROUND An association between prenatal diethylstilbestrol (DES) exposure and cancer in men, especially testicular cancer, has been suspected, but findings from case-control studies have been inconsistent. This study was conducted to investigate the association between prenatal DES exposure and cancer risk in men via prospective follow-up. METHODS A total of 3613 men whose prenatal DES exposure status was known were followed from 1978 through 1994. The overall and site-specific cancer incidence rates among the DES-exposed men were compared with those of the unexposed men in the study and with population-based rates. The relative rate (RR) was used to assess the strength of the association between prenatal DES exposure and cancer development. All statistical tests were two-sided. RESULTS Overall cancer rates among DES-exposed men were similar to those among unexposed men (RR = 1.07; 95% confidence interval [CI] = 0.58 to 1.96) and to national rates (RR = 0.99; 95% CI = 0.65 to 1.44). Testicular cancer may be elevated among DES-exposed men, since the RRs for testicular cancer were 3.05 (95% CI = 0.65 to 22.0) times those of unexposed men in the study and 2.04 (95% CI = 0.82 to 4.20) times those of males in the population-based rates. The higher rate of testicular cancer in the DES-exposed men is, however, also compatible with a chance observation. CONCLUSIONS To date, men exposed to DES in utero do not appear to have an increased risk of most cancers. It remains uncertain, however, whether prenatal DES exposure is associated with testicular cancer.

Abstract
One thousand consecutive cases of surgically proven endometriosis were reviewed to evaluate the frequency and types of pelvic cancers that were associated with ovarian and extraovarian endometriosis. The frequency and types of histologic abnormalities present in the eutopic endometrium when cancers were noted in endometriosis were also evaluated. In the large subset of cases for which the authors were the primary pathologists and all foci of endometriosis were recorded, the frequency of malignancy was 10.8%. In contrast, the frequency was only 3.2% in cases diagnosed by others previously in our institution. Cancers were more commonly found in ovaries when endometriosis was present in that ovary (5%) compared to when endometriosis was present at other sites (1%). Clear cell and endometrioid carcinomas were the malignancies most commonly seen in ovaries containing endometriosis, while clear cell adenocarcinoma and adenosarcoma were most commonly seen in conjunction with extraovarian endometriosis. The association of endometriosis with endometrioid and clear cell carcinoma was much stronger than that of serous and mucinous tumors (p < .01). Concurrent endometrial pathology was commonly seen in cases of malignant transformation of endometriosis (32% of cases).

Abstract
OBJECTIVE Müllerian inclusion cysts (MIC) are small benign appearing glands that are occasionally noted in lymph nodes and peritoneal biopsies. They occur most frequently in women with serous ovarian tumors, with borderline tumors (SBOT) having a higher incidence than invasive cancers. The aim of this study was to examine whether MIC and SBOT have identical K-ras mutations, which would suggest that they are related. Methods. Six patients in whom adequate tissue was available from SBOT, MIC, and normal tissue were identified from a consecutive series of patients with SBOT who underwent lymph node sampling from 1992 to 1997 at Duke University Medical Center. DNA extraction was performed using laser capture microdissection. Exon 1 of the K-ras gene was amplified using PCR and subjected to single-strand conformation analysis to screen for mutations. Shifted bands were sequenced to confirm the presence of mutations. RESULTS Mutations in codon 12 of K-ras were found in three of six (50%) SBOT. In two of these three cases, the identical mutation was found in the SBOT and the MIC (gly to val in both cases), but not in the corresponding normal DNA. In one case, a mutation was seen in the ovarian tumor (gly to asp), but not in the corresponding MIC. CONCLUSIONS Mutations in codon 12 of the K-ras gene are a hallmark of serous borderline tumors. The presence of identical K-ras mutations in some SBOT and their associated MIC suggests that they are related processes. Both may arise due to a field effect, or alternatively some MIC may represent metastases from the primary ovarian tumor.

Abstract
Smooth-muscle tumors of uterine origin encompass a broad family of neoplasms. The leiomyoma, by far the most common of all the neoplasms, generally is hormone sensitive, with rates of growth semiquantitatively related to estrogen and progesterone receptor levels. Several forms of degenerative change can occur in the leiomyoma. The most common is hyaline degeneration, which is important in that it should not be mistaken for the coagulative tumor cell necrosis seen in leiomyosarcoma. Red degeneration (necrobiosis) is a form of degeneration that occurs characteristically but not exclusively in pregnancy, and the process is often the cause of pain and fever. Several forms of treatment have been used medically in the treatment of leiomyoma. Gonadotropin-releasing hormone analogs or agonists or selective arterial embolization with polyvinylformaldehyde particles may lead to substantial degeneration or infarction of the leiomyoma, respectively. Several variants of leiomyoma, the cellular and symplastic leiomyomas, are important to recognize, as they can be misinterpreted as sarcoma. In addition, there are two unusual growth patterns of leiomyoma that are important to recognize. Both the benign metastasizing leiomyoma and disseminated peritoneal leiomyomatosis are found outside the uterus, and neither is malignant. Recent studies offer insights into their origin and hormonal influences. From a diagnostic and therapeutic point of view, the leiomyosarcoma, while rare, is clinically of great import. Coagulative necrosis, cytologic atypia, and mitotic counts are all important in diagnosing the condition.

Abstract
BACKGROUND Blacks are less likely than whites to develop bladder cancer; although once diagnosed, blacks experience poorer survival. This study sought to examine multiple biological and behavioral factors and their influence on extent of disease. METHODS A population-based cohort of black bladder cancer patients and a random sample of frequency-matched white bladder cancer patients, stratified by age, gender, and race were identified through cancer registry systems in metropolitan Atlanta, New Orleans, and the San Francisco/Oakland area. Patients were ages 20-79 years at bladder cancer diagnosis from 1985-1987, and had no previous cancer history. Medical records were reviewed at initial diagnosis. Of the patients selected for study, a total of 77% of patients was interviewed. Grade, stage, and other variables (including age, socioeconomic status, symptom duration, and smoking history) were recorded. Extent of disease was modeled in 497 patients with urothelial carcinoma using logistic regression. RESULTS Extent of disease at diagnosis was significantly greater in Blacks than in Whites. Older age group, higher tumor grade, larger tumors, and presence of carcinoma in situ were related to greater extent of disease in blacks and in whites. Large disparities between blacks and whites were found for socioeconomic status and source of care. Blacks had greater symptom duration and higher grade. Black women were more likely to have invasive disease than white women; this difference was not seen among men. Blacks in unskilled occupational categories, perhaps reflecting socioeconomic factors, were at much higher risk for muscle invasion than whites. CONCLUSIONS While specific relationships between variables were noted, an overall pattern defining black and white differences in stage did not emerge. Future studies should examine the basis upon which occupation and life style factors operate by using biochemical and molecular methods to study the genetic factors involved.

Abstract
Glandular inclusions that appear morphologically benign are occasionally found in lymph nodes as well as in peritoneal and omental biopsies. In patients with gynecologic malignancies, the nature and significance of these mullerian inclusion cysts (MIC) present a diagnostic challenge with regard to whether they are benign and incidental or are related to the coincident tumor for which surgery is being performed. Sixty-two cases of MIC were prospectively identified during a 6-year period. The frequencies were calculated and stratified by lymph node chain distribution, primary tumor site, and primary tumor type. MIC appeared as small cysts lined by a serous (mullerian)-type, cytologically bland, cuboidal to columnar epithelium with a simple architecture. Among 62 women, MIC was found in lymph nodes (27 cases), pelvic peritoneum (19 cases), omentum (16 cases), bowel serosa (9 cases), uterine serosa (8 cases), and parametrial connective tissues (4 cases). Among a set of 417 consecutive cases in which lymphadenectomy was performed, 46 (11%) women had MIC. The MIC involved multiple sites (26 cases in the peritoneum/omentum and 27 in lymph nodes). The primary tumor was in the ovary in 32 of the 46 women with MIC (70%) and of these, 17 were borderline serous (53%). Sixty-two of 6,154 lymph nodes examined contained MIC (1.0%). 3.2% of nodes contained MIC in which the primary tumor arose in the ovary, but only 0.1% with either endometrial or cervical tumors (chi2, p <0.00001). The lymph nodes most often involved by MIC were from para-aortic sites (40%), which reflect the primary drainage route from the ovary. Not uncommonly, neighboring areas in the same lymph node group with MIC disclosed separate foci of obvious metastatic borderline tumor (4 of 10; 40%). In summary, the increased frequency of MIC in lymph nodes sampled for primary ovarian malignancies suggests that MIC in some cases, rather than being benign, incidental inclusions, are more likely bland-appearing forms of metastatic tumor. The preponderance of inclusions occurs with serous ovarian tumors of borderline malignancy, and the inclusions are overrepresented in the lymph nodes that primarily receive drainage from the ovary.

Abstract
PURPOSE The aim of this study was to compare survival and recurrence in clinical and surgical stage I-II papillary serous (PS), clear cell (CC), and endometrioid (EM) cancers of the endometrium and examine the prognostic utility of myometrial invasion. METHODS Clinical, surgicopathologic, and survival data were retrospectively collected on 574 clinical stage I-II endometrial cancer patients, including 53 PS and 18 CC (based on postoperative histology), undergoing hysterectomy at Duke University Medical Center between 1967 and 1990. All staging material was available and reexamined prior to this analysis, and FIGO surgical staging was retrospectively assigned. Prognostic variables examined included age, stage, grade, myometrial invasion, lymph-vascular space invasion (LVSI), and histology. PS and CC histologic subtypes were compared as both common category and discrete categories versus EM, EM grade 1 (EM1), EM grade 2 (EM2), and EM grade 3 (EM3). Statistical analyses were performed using chi(2), Fisher's exact, and Wilcoxon rank sum tests, Cox regression analysis, and Kaplan-Meier survival analysis. RESULTS PS tumors accounted for 9%, CC for 3%, and EM for 88% of cases. Recurrences were more frequent among PS (38%) and CC (22%) compared with EM (9%) (P < 0.001 and 0.08, respectively), and PS recurred more frequently than EM3 alone (20%) (P = 0.06). Among PS, CC, and EM3 patients with recurrences there were no statistical differences in the proportion that received preoperative or postoperative radiotherapy or chemotherapy. Prognostic factors for shorter survival included age >=60, surgical stage III+IV, presence of LVSI, histology (PS, CC, or EM3), and >=50% myometrial invasion. The estimated 5-year survival of PS+CC patients with <2 mm myometrial invasion is 0.56 compared to 0.93 for EM patients (P < 0. 001). PS + CC tumors confined to the endometrium had a 5-year survival of 0.60 compared to 0.98 and 1.00 for EM and EM3, respectively. The 5-year survival for surgically staged IA patients (0.57) was not different from stages IB and IC combined (0.53) (P = 0.72). The 5-year survival for surgical stage I + II PS + CC patients (0.56) was comparable to that for clinical stage I + II PS + CC patients (0.46) and remained significantly smaller than that for EM patients (0.86) (P < 0.001). CONCLUSION Recurrences are more frequent among PS and CC tumors compared with EM and among PS compared with EM3. When controlled for surgical stage I-II tumors, 5-year survival for PS + CC patients remains comparable to that of clinical stage I-II patients and below that of EM. Prognostic factors for survival in PS and CC patients include age, stage, and LVSI. PS, CC, and EM3 subtypes together are predictors of poor survival. Thorough extended surgical staging is indicated in PS and CC tumors, and prospective trials of aggressive adjuvant therapies for surgical stage I-II tumors are needed to improve outcome in PS and CC patients.

Abstract
PURPOSE The aim of this study was to identify similarities and differences in epidemiologic and surgicopathologic staging results for papillary serous (PS) and clear cell (CC) endometrial cancers compared with endometrioid (EM) carcinoma of the endometrium. METHODS Clinical and surgicopathologic data were retrospectively collected on 574 clinical stage I-II endometrial cancer patients, including 53 PS and 18 CC (based on postoperative histology), undergoing hysterectomy at Duke University Medical Center between 1967 and 1990. All staging material was available and reexamined prior to this analysis, and FIGO surgical staging was retrospectively assigned. PS and CC histologic subtypes were compared both as a common category and as discrete categories versus EM, EM grade 1 (EM1), EM grade 2 (EM2), and EM grade 3 (EM3). Fisher's exact test was used to compare proportions with unordered categories (2x2 tables), while the chi(2) test for trend was used to compare proportions in 3x2 tables with ordered categories. Differences in medians were compared with the Wilcoxon rank-sum test. RESULTS PS tumors accounted for 8%, CC for 2%, and EM for 90% of cases. Overall, 14% of tumors were changed to a different postoperative histology including 64% of PS, 50% of CC, and 8% of EM. Postoperative histology changes were 4% for EM1 and 21% for EM3. PS, CC, and EM3 had more surgical sampling performed than for other EM. Rates for lymph node dissections were similar for EM3 (81%), PS (72%), and CC (67%) tumors, although metastases were more frequent for PS and CC compared with EM3. When PS tumors were confined to the endometrium, paraaortic metastases occurred in 13%. LVSI increased with EM grade and was highest for PS and CC. Upstaging to surgical stage III-IV occurred in 47% of PS, 39% of CC, and 12% of EM. The majority of PS and CC tumors were confined to the inner one-third of the myometrium, compared with EM tumors, where grade correlated with depth of myometrial invasion. Extrauterine metastases occurred in 55% of PS and 45% of CC tumors confined to the inner one-half, compared with 17% of EM3. CONCLUSION Frequent changes from preoperative to postoperative histology and grade may contribute to misassignment of preoperative and intraoperative risk as determined by depth of myometrial invasion for PS and CC patients. The higher frequency of extrauterine metastases in PS and CC tumors compared with EM3, despite similar surgical sampling rates, supports a more virulent behavior. The poor correlation between depth of myometrial invasion and risk for extrauterine metastases helps to explain poorer survival in PS and CC patients, in addition to more frequent upstaging. These results support routine extended surgical staging for women with preoperative or intraoperative diagnosis of PS and CC tumors. Intraoperative assessment of tumor grade and histology may be indicated and warrants further investigation.

Abstract
Leiomyomatosis peritonealis disseminata (LPD) is a rare condition that primarily affects women of reproductive age. Immunohistochemical studies were performed in four cases: LPD from a premenopausal woman on oral contraceptives (one case); LPD associated with postpartum massive ectopic decidual reaction (one case); and LPD from a perimenopausal and a postmenopausal woman. Progesterone receptor activity was present in nine of nine cases, and eight of eight cases were strongly positive for vimentin; reactivity for cytokeratin was uniformly negative. Most cases had a pattern of staining typical of smooth muscle tumors with expression of desmin, smooth muscle actin, and muscle-specific actin. Although estrogen receptor was detected in most cases, reactivity was notably absent (one case) or weak (one case) in nodules with a prominent decidual reaction. Expression of CD 34, a marker for which LPD staining characteristics have not been previously reported, varied from absent to weak. Peritoneal nodules from the postmenopausal woman lacked staining for both estrogen receptor and desmin, smooth muscle actin and muscle-specific actin were only focally expressed, whereas staining for CD 34 was focally intense. Uterine myometrium and leiomyomata were positive for progesterone and estrogen receptor, vimentin, desmin, smooth muscle actin, and muscle-specific actin. Cytokeratin expression was absent. CD 34 exhibited weak staining in leiomyomata, but was absent from myometrium. Progesterone receptor appears to be uniformly expressed in LPD nodules from premenopausal and postmenopausal women, a finding supporting the contention that hormones influence the development of LPD in all cases, regardless of menopausal status.

Abstract
Differential staining with cytokeratin (CK)-7 and CK-20, two members of a complex family of proteins in human epithelial cells, proved critical in showing that the extremely well-differentiated goblet-cell (intestinal) mucinous epithelium lining the surface of the endometrium and endocervix in two patients and the fallopian tube in one was identical to that of the coincident appendiceal neoplasms. One of these patients also had a large ovarian tumor that grossly and microscopically resembled a mucinous cystadenoma of borderline malignancy and would have been considered primary except for the CK stains (CK-20 positive and CK-7 negative), which suggested metastasis from the appendix, presumably by a transtubal route.

Abstract
CONTEXT The association between in utero exposure to diethylstilbestrol (DES) and clear cell adenocarcinoma (CCA) of the vagina and cervix is well known, yet there has been no systematic study of DES-exposed daughters to determine whether they have an increased risk of other cancers. As many as 3 million women in the United States may have been exposed to DES in utero. OBJECTIVE To determine whether women exposed to DES in utero have a higher risk of cancer after an average of 16 years of follow-up. DESIGN A cohort study with mailed questionnaires and medical record review of reported cancer outcomes. PARTICIPANTS A cohort of 4536 DES-exposed daughters (of whom 81% responded) and 1544 unexposed daughters (of whom 79% responded) who were first identified in the mid-1970s. MAIN OUTCOME MEASURES Cancer incidence in DES-exposed daughters compared with population-based rates and compared with cancer incidence in unexposed daughters. RESULTS To date, DES-exposed daughters have not experienced an increased risk for all cancers (rate ratio, 0.96; 95% confidence interval [CI], 0.58-1.56) or for individual cancer sites, except for CCA. Three cases of vaginal CCA occurred among the exposed daughters, resulting in a standardized incidence ratio of 40.7 (95% CI, 13.1-126.2) in comparison with population-based incidence rates. The rate ratio for breast cancer was 1.18 (95% CI, 0.56-2.49); adjustment for known risk factors did not alter this result. CONCLUSIONS Thus far, DES-exposed daughters show no increased cancer risk, except for CCA. Nevertheless, because exposed daughters included in our study were, on average, only 38 years old at last follow-up, continued surveillance is warranted to determine whether any increases in cancer risk occur during the menopausal years.

Abstract
Extragenital metastases to the endometrium are unusual, but several histologic features have been suggested as highly suggestive or even pathognomonic for this diagnosis. We report an endometrial carcinoma with a prominent signet-ring cell morphology and a diffusely permeative pattern of infiltration, features that have been reported as indicating an extragenital metastasis. To the best of our knowledge, this is the first reported case of a signet-ring cell carcinoma of the endometrium. Gynecological pathologists should be aware of this entity because of its potential primary of metastatic signet-ring carcinoma to be endometrium.

Abstract
This study evaluates the morphologic features of squamous epithelial repair of the uterine cervix, a condition describing a state of regeneration, and compares them with the features of its two histologic mimics, squamous metaplasia and mild dysplasia. The materials examined were from 20 patients with a histologic diagnosis of repair, 42 with cervical biopsy specimens of acceptable quality obtained within 3 weeks of a cervical smear showing repair, and 20 each with squamous metaplasia or mild dysplasia. Specimens with repair disclosed distinctive morphologic characteristics. On low-power magnification, the stroma was chronically inflamed (100%), often floridly (55%). The nuclei were uniform with absent or minimal pleomorphism (90%). The chromatin was bland and evenly distributed (70%). Nucleoli of a bull's eye or macronucleolar appearance (45%) were easily found. Mildly dysplastic epithelium, unlike reparative epithelium, was infrequently associated with an intensely inflamed stroma (20%); its nuclei were pleomorphic (100%) and commonly displayed coarse chromatin (75%) and mitoses (60%). Metaplastic epithelium ws also infrequently associated with an intensely inflamed stroma (10%). Nuclear pleomorphism (10%) and mitotic figures were infrequent (10%), never atypical (0%), and always basally located. Most nuclei had nucleoli, but the majority were small (80%). This study indicates that most cases of repair, mild dysplasia, and metaplasia can be readily distinguished, although due to overlapping features, some cases are difficult to classify as shown by interobserver variability.

Abstract
An effective, prospective, computer-guided method of correlation is reported. The mechanism for identification of cases, comparison of diagnoses, and reconciliation of discrepancies are explained. The results are similar to prior, retrospective, correlation studies. The benefits specific to this unique prospective approach include optimal capture of cases for correlation, minimization of errors before diagnoses are released to clinicians and patients, and internal standardization of diagnostic criteria. Three thousand four hundred and four consecutive paired cervicovaginal cytologies and biopsies were accessioned at the Pathology Department of Duke University Medical Center over a 43-month period. Of these, 481 paired cases (14%) had discordant diagnoses, defined as differing more than one degree of dysplasia or as dysplasia or carcinoma identified by only one modality. Additional evaluation reconciled the diagnostic differences in 35 cases. Eighteen initial diagnostic differences arose from cytologic screening errors, 16 from interpretive errors by staff pathologists, and one from superficial initial histologic sections. The remaining 446 discordances were attributed to sampling differences. The cytologic smear contained the diagnostic lesion in 40% of the cases and the biopsy the remainder, emphasizing the utility of pairing these sampling techniques in patients at risk for dysplasia.

Abstract
OBJECTIVE This study examined the relationship of clinicopathologic, health status, medical system, and socioeconomic factors to differences in stage at diagnosis of endometrial cancer in black and white patients. STUDY DESIGN A population-based study of 130 black and 329 white patients with invasive endometrial cancer was conducted as part of the National Cancer Institute's Black/White Cancer Survival Study. Logistic regression was used to determine the relative importance of factors thought to be related to stage at diagnosis after age and geographic location were adjusted for. RESULTS High-grade (poorly differentiated) lesions increased the risk for stage III or IV disease (odds ratio 8.3, 95% confidence interval 3.4 to 20.3), as did serous histologic subtype (odds ratio 3.5, 95% confidence interval 1.4 to 8.8) and no usual source of care (odds ratio 5.5, 95% confidence interval 1.4 to 20.9). In the final statistical model these three factors also accounted for the majority of the excess risk of advanced stage for blacks. CONCLUSIONS Black-white racial disparities in stage at diagnosis appear to be related to higher-grade lesions and more aggressive histologic subtypes occurring more frequently in black patients with endometrial cancer.

Abstract
Black women with endometrial cancer have more advanced disease and less favorable tumor grade than do white women. This study evaluated whether racial differences in tumor grade could be explained by hormone-related factors and other putative determinants of grade. Subjects included 207 white and 81 black postmenopausal women diagnosed with primary cancer of the uterine corpus between 1985 and 1987. Blacks had poorer tumor grade than whites (odds ratio for FIGO grade 2 versus grade 1 is 1.8; odds ratio for grade 3 versus grade 1 is 2.8). Over 75% of the excess of poorly differentiated tumors versus well-differentiated tumors among blacks could be explained by racial differences in use of replacement estrogens, age at first pregnancy, history of oophorectomy, poverty, stage of disease, use of screening, and access to health care. The most prominent factor was estrogen therapy, which was associated with favorable tumor grade and was used much less frequently by blacks. Although not statistically significant, a moderate racial difference in tumor grade remained after control of the potential explanatory explanatory variables. This may reflect true biologic variation between blacks and whites and may explain, in part, the observation that blacks with endometrial cancer have a worse prognosis.

Abstract
This report describes two cases of malignant serous cancers with areas of borderline malignancy, which appear to have arisen within benign glandular inclusions of coelomic origin in pelvic or para-aortic lymph nodes. The patients were 44 and 62 years of age. In both cases the nodes contained benign glandular inclusions lined by a single layer of epithelium which resembled that of tubal epithelium. The location of the glandular epithelium varied from within the fat near the node to intracapsular, subcapsular, or interfollicular positions. The number of glands ranged from few to extensive. In both cases the glandular inclusions disclosed epithelial proliferations, ranging from minor degrees of stratification with formation of small papillae of atypical cells (borderline serous tumor) to almost solid tumor typical of serous cancer. In both cases, the borderline and cancerous tumors exhibited areas of transition which appeared to arise from benign glands. Although benign glandular inclusions of coelomic origin are well documented to occur in pelvic or para-aortic lymph nodes of 5-20% of women and have been considered to be of significance only because of the possibility of the misdiagnosis of cancer, it should now be recognized that the glandular inclusion cysts themselves can become neoplastic.

Abstract
OBJECTIVE To test the hypothesis tha a very-low-dose regimen of vaginal estrogen would provide effective relief from atrophic vaginitis without endometrial proliferation. METHODS Twenty postmenopausal women with symptoms, signs, and cytologic evidence of atrophic vaginitis were enrolled. Each subject was treated with 0.3 mg of conjugated estrogens, administered vaginally 3 nights per week for 6 months. We examined the following outcomes: symptoms, vaginal cellular (cytologic) maturity, endometrial histology, sonographic evaluation of endometrial thickness, Doppler measures of uterine artery blood flow, and serum levels of estrone and estradiol. Pre- and post-treatment data were compared for each subject. RESULTS Satisfactory relief of symptoms occurred in 19 of 20 cases. Vaginal cellular maturation improved significantly with therapy (P < .01). There were no significant changes in endometrial thickness, uterine artery blood flow, or serum estrogen levels. Endometrial proliferation was observed in one case. CONCLUSIONS Relief from atrophic vaginitis can be achieved with 0.3 mg of conjugated estrogens administered vaginally three times per week. Endometrial proliferation may occur at this low dose, albeit rarely.

Abstract
Since overexpression of mutant p53 protein is a common feature of invasive epithelial ovarian cancers, we investigated whether overexpression of the p53 tumor suppressor gene product occurs in benign and borderline epithelial ovarian tumors. Immunohistochemical staining for p53 was performed in frozen samples of 17 benign tumors and in 49 borderline tumors (4 frozen, 45 paraffin embedded). Overexpression of p53 was observed in 0/17 (0%) benign ovarian tumors and 2/49 (4%) borderline tumors. Overexpression of p53 in borderline tumors was only seen in advanced stage cases; overexpression was seen in 2/8 (25%) stage III cases, but not in any of 41 stage I/II cases. In conclusion, overexpression of p53 is not a feature of benign epithelial ovarian tumors or early-stage borderline ovarian tumors. Similar to invasive epithelial ovarian cancers, however, a fraction of metastatic borderline tumors also overexpress p53.

Abstract
OBJECTIVES This study examines the gonoducts during the ambisexual stage of human fetal development to define their ultrastructural characteristics, including the origin and antomic relationship of the mesonephric and paramesonephric ducts during gonoductal development. STUDY DESIGN The reproductive tracts from five fetuses ranging in gestational age from 35 to 45 days were processed for ultrastructural examination. The developing mesonephric ducts, paramesonephric ducts, and their surrounding mesenchyme were studied with a Phillips 300 transmission electron microscope. RESULTS The mesonephric ducts and paramesonephric ducts have distinctive cytoplasmic and cell surface ultrastructural characteristics, as well as different morphologic patterns of epithelial-mesenchymal interaction. Cephalad portions of mesonephric ducts and paramesonephric ducts are separated by mesenchyme, but more caudal aspects move progressively closer until they are juxtaposed but separate. CONCLUSIONS Early mesonephric ducts and paramesonephric ducts may be distinguished because of their distinctive ultrastructural features; epithelial-mesenchymal interaction may be important in their differentiation and maintenance; both gonoducts retain their morphologic identity throughout, supporting their separate origins.

Abstract
The Cancer and Steroid Hormone Study, a multicenter, population-based, case-control study of ovarian, breast, and endometrial cancer in women 20 to 54 years of age, permitted the diagnoses of contributing pathologists to be compared with those of a panel of three gynecologic pathologists. A diagnosis of ovarian cancer was made by contributing pathologists on 477 subjects. Agreement between the two groups of pathologists was 97% for primary epithelial ovarian cancer and 89% for primary nonepithelial ovarian malignancies. Agreement on diagnosis of major cellular subtypes of ovarian malignancy ranged between 73% for endometrioid cancer and 100% for clear cell carcinomas. We conclude that the diagnosis of pathologic features of primary ovarian cancer is highly predictable. Nonetheless, diagnosis by histologic type varies sufficiently that a review process should be considered for clinical or investigative decisions involving specific histologic diagnoses of ovarian cancer.

Abstract
The present case of sarcoidosis of the uterus and the previously reported cases are reviewed. Uterine sarcoidosis is usually detected during the investigation of abnormal uterine bleeding in patients with prior evidence of sarcoidosis in another site. However, in several of the reviewed cases, either the uterus was the site of the initial diagnosis of sarcoidosis or its involvement was detected soon afterward. When hysterectomies were performed on patients with endometrial involvement, the myometrium was usually found to contain nonnecrotizing epithelioid granulomas. By contrast, uterine tuberculosis usually spares the myometrium. The differential diagnosis between uterine sarcoidosis and uterine tuberculosis is discussed.

Abstract
One million, six hundred thirty-two thousand, eight hundred forty-seven women from two independent populations in the United States received cytologic screening during a two-year period. Condylomatous lesions (human papillomavirus [HPV] infections) were the most frequent cytologic abnormality in women in both the Planned Parenthood and private sector groups (prevalence rates of 18.6 to 19.0 in women between ages 15 to 19). The prevalence rates of mild-to-moderate dysplasia were also similar in both populations, with the highest frequencies being between ages 25 to 29. Severe dysplasia and carcinoma in situ were most frequent between ages 35 to 39. In both populations, women with condylomatous changes coexisting with dysplastic changes were about ten years younger, grade-for-grade of severity of the lesion, than women without evidence of HPV infection. Since HPV infection is believed to represent the soil from which neoplasm develops, both the frequency of condyloma and the occurrence of dysplasia and cancer in young women suggest that women should begin regular screening programs while in their teens or after they become sexually active.

Abstract
The frequency of positive serological tests for Chlamydia trachomatis, the most common sexually transmitted pathogen in the United States, was assessed in 18,622 specimens derived from New Jersey clinics. From the results, 13 percent female patients and 17 percent male patients were reactive for chlamydial antigen.

Abstract
It has been questioned whether prenatal exposure to progesterone, like exposure to diethylstilbestrol (DES), results in teratogenic abnormalities of the upper and lower genital tract in human females. Through the use of a recently described model in which human fetal reproductive tracts can be transplanted and grown in vivo for extended periods in athymic nude mice, genital tracts from human female fetuses, ages 7 to 18 weeks postovulation, were grafted into castrated murine hosts and grown for 4 to 10 weeks in the presence or absence of continuous exposure to progesterone. Substantial growth was observed. For all specimens, the morphogenetic process proceeded normally, resulting in the harmonious organization of a complete, well differentiated genital tract composed of fallopian tubes, uterine corpus, and cervix and vagina. The fallopian tubes were highly convoluted and disclosed fimbria. The uterine corpus was lined by a simple columnar epithelium; two layers of stroma in the wall were distinctly separated from each other. In the older specimens, the outer layer of stroma had assumed microscopic properties diagnostic of smooth muscle (myometrium). In the majority of specimens the region of the cervix/vagina disclosed the development of a fornix-like evagination at which point or slightly cranially there was a gradual but defined transition from columnar epithelium to squamous epithelium. The inner layer of endometrial stroma tapered and disappeared at or close to the squamocolumnar junction. The vaginal stroma was a single homogeneous layer and was continuous with the myometrium of the uterine corpus. In the context of this model system, prenatal exposure of the developing human female genital tract of progesterone was not associated with any obvious teratogenic effects.

Abstract
Two and three-tenths percent of cervical smears disclosed abnormalities from among 1,045,059 submitted for processing and examination by the Cancer Screening Service. The smears came from 198 Planned Parenthood Family Planning Clinics in 23 States during a 3-year period. Mild to moderate dysplasia was most frequent in women 25 to 29 years of age (prevalence rate, 25.7/1000), severe dysplasia and carcinoma in situ in women 35 to 39 years of age (prevalence rate, 4.6/1000), and invasive carcinoma in women older than 50 years of age (prevalence rate, 0.47/1000). All lesions also were encountered in younger women. Mild dysplasia was found in girls as young as 10 years of age, severe dysplasia in girls as young as 15 years, and invasive carcinoma in women as young as 20 years. The large number of young women with abnormalities suggests that availability of screening programs for sexually active women is important.

Abstract
We conducted an incidence study to determine the occurrence rates of clear cell adenocarcinoma (CCAC) of the vagina and cervix in young women (born in 1940 and thereafter), and a case-series analysis, focusing on the maternal history of pregnancy and delivery and in-utero exposure to diethylstilbestrol (DES). Overall, 10 cases of CCAC had been listed in the files of the Connecticut State Tumor Registry prior to the study, and each of the 10 cases were confirmed as valid. In addition, another 10 cases, all previously undetected, were found after the tissue slides of young women listed as having other cancers of the vagina and cervix were reviewed by expert pathologists, suggesting that prior estimates of the incidence rate for CCAC must be misleading unless special efforts are taken to identify undetected cases. The incidence rates of vaginal CCAC (11 cases total) were highest in 1975-1979, and decreased slightly during 1980-1982. In the cervix (nine cases total), the rate increased consistently since 1970. History of in-utero exposure to diethylstilbestrol was obtained for five of eight vaginal cases and four of eight cervical cases of CCAC. In all nine cases, exposure to diethylstilbestrol was associated with a history of bleeding during the pregnancy or prior miscarriage. We conclude that the finding of stable (or rising) incidence rates for CCAC occurring nearly 30 years after the marked decrease in diethylstilbestrol sales emphasizes the need for continued clinical and epidemiologic studies of the etiology and clinical course of CCAC.

Abstract
The potential estrogenicity and teratogenicity of triphenylethylene antiestrogens were examined in 54 genital tracts isolated from 4- to 19-week-old human female fetuses and grown for 1 to 2 months in untreated athymic nude mice or host mice treated by subcutaneous pellet with the antiestrogens clomiphene and tamoxifen or the synthetic estrogen diethylstilbestrol (DES). In specimens grown to a gestational age equivalent of 15 weeks or less, the vagina and urogenital sinus were lined by an immature squamous epithelium, which were similar in both drug-treated and untreated specimens. Proliferation and maturation of the squamous vaginal epithelium were observed in specimens treated with clomiphene, tamoxifen, or DES only when grown to a gestational age equivalent of 16 weeks or more. Formation of endometrial and cervical glands proceeded in 87 per cent (13 of 15) of control specimens grown to a gestational age equivalent of 13 weeks or more in untreated hosts. By contrast, age-matched drug-treated specimens contained glands in only 44 per cent (12 of 27) of specimens. In the developing uterine corpus of untreated controls, the uterine mesenchyme segregated into inner (endometrial stroma) and outer (myometrial) layers; whereas in drug-treated specimens, condensation and segregation of the mesenchyme were greatly impaired. The fallopian tube was also affected by clomiphene and tamoxifen (and to a lesser extent by DES) in that its epithelium was hyperplastic and disorganized. The complex mucosal plications characteristic of the fallopian tube were also distorted in drug-treated specimens. These results emphasize the heretofore unrecognized estrogenicity and potential teratogenicity of triphenylethylene antiestrogens on the developing human genital tract and emphasize the need for caution to prevent inadvertent exposure of the developing fetus to these compounds.

Abstract
Clinical and necropsy findings in 13 intravenous drug abusers who died of the acquired immunodeficiency syndrome (AIDS) were reviewed and compared with findings in eight patients who acquired the infection through sexual exposure, the most common mode of transmission in AIDS. No differences were found in lymphocyte counts or duration of survival, despite reports that the degree of immunosuppression in intravenous drug abusers with AIDS differs from that in homosexuals. Neoplasms were found in 25 per cent of patients with sexual risks, but not in any drug abusers (0 per cent). Two opportunistic infections (toxoplasmosis and cytomegalovirus pneumonia and esophagitis) were more common in the intravenous drug abuser group. Although cytomegalovirus has been associated with Kaposi's sarcoma, this association was not found in this study. The postmortem findings in both groups were otherwise similar.

Abstract
This study reports the sexual history of a group of young women participating in an epidemiologic project. The methods used to recruit and interview the participants minimized self-selection bias. Results of over 11,000 interviews with 1,892 participants showed that 72.3% should be considered at high risk for developing cervical cancer and its precursors and should be screened regularly for this disease.

Abstract
An autoradiographic study of nuclear estrogen binding was performed in developing human urogenital sinuses and vaginas derived from first and second trimester specimens. Nuclear estrogen binding was detected in all specimens greater than or equal to 10 weeks of gestation within mesenchymal cells. Nuclear labelling within epithelium was observed only in those specimens whose development and differentiation was advanced. Thus, mesenchyme appears to be the initial estrogen target tissue within the developing human vagina and may play a fundamental role in estrogen-induced teratogenesis of the human genital tract.

Abstract
The infectious pathogens and associated cellular reactions in 75 pulmonary cytological specimens obtained largely by fiberoptic bronchoscopy from 36 patients with the acquired immune deficiency syndrome are described and correlated with the biopsy specimens. An opportunistic pathogen was diagnosed in 33% of cytological preparations. Pneumocystis carinii was encountered most frequently; Cryptococcus neoformans and cytomegalovirus were also seen. The polymorphonuclear neutrophil was the predominant inflammatory cell. Cells of secondary import were bronchial cells and type II pneumocytes with atypia and hyperplasia. Bronchoalveolar lavage had the highest yield, positive predictive value, and sensitivity for all pathogens and for P. carinii. An opportunistic pathogen was diagnosed in 69% of patients utilizing histological material and in 33% using cytological samples; the rate of diagnosis increased to 72% when the samples were combined.

Abstract
The use of conjunctival smears to diagnose infantile Chlamydia trachomatis infection increased sixteen-fold in our hospital between the years 1979 and 1984. The present study was conducted to compare Papanicolaou and Giemsa staining methods with the avidin-biotin technique of immunostaining utilizing a highly specific antichlamydial monoclonal antibody. On retrospective review of 33 patients, chlamydial infection was diagnosed in 61% of the Papanicolaou-stained and 64% of the Giemsa-stained slides. After the Papanicolaou-stained slides were destained and immunostained with the antichlamydial antibody, round particles corresponding in size to elementary and reticulate bodies were readily seen in 79% of the cases. In comparison with the immunoperoxidase method, the sensitivity and specificity of Papanicolaou staining were 73% and 86%, respectively, while the corresponding figures for Giemsa staining were 77% and 100%, respectively. The study established the applicability of the immunoperoxidase method to this clinical condition, confirmed the accuracy of diagnoses with routine stains and highlighted the increasing incidence of chlamydial conjunctivitis in our hospital population.

Abstract
Vaginal adenosis was evaluated in 41 women, all of whom had been born prior to the diethylstilbestrol (DES) era, and compared with the adenosis commonly encountered in DES-exposed progeny. The patients were 24 to 88 years of age (median, 44 years). Six of the women were symptomatic, and in four of these six the glands were enmeshed in a marked inflammatory infiltrate. In an additional 26 women the adenosis was discovered as incidental, nonsymptomatic macroscopic nodules or cysts. The remaining nine cases of adenosis were discovered by pathologists. Three types of epithelia characterized the glands: mucinous, tuboendometrial, and embryonic. Mucinous columnar cells resembling the lining of the normal endocervix and tuboendometrial cells resembling the lining of the normal fallopian tube or endometrium constituted the glands exclusively in 22 and eight specimens, respectively, and as a mixture in seven. The glands lined by mucinous cells most often presented clinically as cysts or nodules. The specimens composed of tuboendometrial cells were most often discovered on microscopic examination. The third type of epithelium, composed of embryonic columnar cells, was encountered in four specimens. These glands, less than 30 micron in greatest diameter, were located at the junction between the lamina propria and the squamous epithelium, and were incidental microscopic findings. It is concluded that the microscopic appearances of adenosis in women born prior to the DES era are identical to those encountered in young women exposed in utero to DES.

Abstract
The case history of a woman with a "female adnexal tumor of probable Wolffian origin" is described in which the neoplasm recurred three times during a 16-year interval and responded with prolonged remission after repeated surgical excision and radiotherapy. Ultrastructural data are given to support the Wolffian nature of the tumor. Although the tumor was considered in the past to be a benign neoplasm, the current report, as well as six others in which the tumor recurred or metastasized, indicates that the female adnexal tumor of probable Wolffian origin should be classified within the International Classification of Disease-Oncology and the Systematized Nomenclature of Medicine nomenclatures as "of low malignant potential."

Abstract
An analysis of 6055 colposcopically directed biopsy specimens from 2635 diethylstilbestrol (DES)-exposed women and 445 biopsy specimens from 277 nonexposed women was undertaken to correlate microscopic findings with colposcopic patterns. All examinations were performed using a standardized protocol which required that each participant have colposcopy, cytologic smears, and biopsy of abnormal colposcopic lesions. The findings of colposcopic "columnar epithelium, gland openings, and Nabothian cysts" correlated most often with glandular epithelium in the biopsy specimen. "White epithelium," which includes three related colposcopic patterns, mosaicism, punctation, and white epithelium, was associated most frequently (82-93% of cases) with squamous metaplasia, but occasionally with dysplasia and carcinoma in situ (CIS)(0-6%). The presence of dysplasia or CIS in any individual biopsy specimen occurred most frequently with the observation of higher graded lesions by colposcopy or a prior diagnosis of dysplasia.

Abstract
A study was undertaken to determine (1) the effects of endogenous Müllerian inhibiting substance (MIS) on the developing human fetal genital tract; (2) the time in fetal life when MIS is first capable of inhibiting the growth of the embryonic Müllerian ducts; and (3) the reversibility of the effects of MIS on the developing male Müllerian ducts. Human fetal reproductive tracts were transplanted and grown for sustained periods in vivo in athymic nude mice. The genital tracts from 12 male human fetuses, ages 51 to 68 days postovulation, were grafted without their associated gonads into castrated murine hosts and grown for 30 to 70 days. Controls consisted of genital tracts from 8 female human fetuses, ages day 53 to 70 that were grown under identical conditions. Male specimens grew to approximately one-half the size of female specimens and disclosed varying degrees of inhibition of the Müllerian duct system from absence of the Müllerian ducts in older specimens (after Day 63) to poorly segregated segments of stroma as the mildest defect (less than Day 61). It is concluded that (1) MIS secretion by the embryonic testes probably begins before Day 51 of gestation; (2) the effects of MIS are progressive during the so-called critical window; (3) the effects of MIS are permanent; and (4) the mesenchyme is an important target of MIS.

Abstract
The incidence rates of dysplasia and carcinoma in situ (CIS) of the cervix and vagina were determined in 3,980 young women exposed prenatally to diethylstilbestrol. Strict criteria were developed to minimize selection bias among the subset of 744 pairs of matched exposed and unexposed (control) cohort participants, all of whom were identified through review of prenatal obstetrical records. A high degree of compliance was achieved throughout the seven-year study period since in each group about 90% of the women remained as active participants, kept 77% of the annual anniversary examinations, and had separate Papanicolaou smears of the cervix and vagina performed in 99% of the anniversary examinations. The incidence rate for dysplasia and CIS was significantly higher in the women exposed to diethylstilbestrol than in those not exposed in the matched cohort (15.7 v 7.9 cases per 1,000 person-years of follow-up). The rates were higher in the exposed women if squamous metaplasia extended to the outer half of the cervix or onto the vagina. In other respects, the matched cohorts were strikingly similar.

Abstract
A pilot study using low-dose preoperative radiation therapy, i.e., 10 Gy in 3 to 4 days as an adjuvant preoperative procedure for grade 2 or 3 (FIGO classification) endometrial carcinoma, was done. The concept of low-dose preoperative radiation therapy is to administer treatment, either surgical or radiotherapeutic, postoperatively according to the surgical and pathologic findings, allowing identification of those patients with previously undiagnosed extensive metastatic disease outside the pelvis found at laparotomy in whom routine pelvic radiation therapy is futile, as well as those patients with relatively low risk of recurrence who may not require further radiotherapy. Forty-four patients with clinical Stage I, grade 2 or 3 with adenocarcinoma of the endometrium were entered into the pilot study. Following surgery, 68% remained Stage I by pathologic examination, and in the remaining patients the stages were changed to II in seven, III in three, and IV in four. Postoperative treatment was administered according to extent of the disease found at surgery. The 4-year actuarial probability of survival rate for the entire group of patients with clinical Stage I disease was 80%; corresponding disease-free rate was 77%. For the Stage I disease confirmed by pathologic examination, the corresponding rate was 96%. The rates for Stages II through IV, as shown by pathologic findings at laparotomy, were 53% and 42%, respectively. In this pilot stud, a treatment policy for clinical Stage I, grade 2 or 3 adenocarcinoma of the endometrium using low-dose preoperative radiation therapy is recommended.
