Screening for early familial ovarian cancer with transvaginal ultrasonography and colour blood flow imaging.

OBJECTIVE--To assess the value of transvaginal ultrasonography with colour blood flow imaging in detecting early ovarian cancer in women with a family history of the disease. DESIGN--Study of self referred symptomless women with a close relative who had developed the disease. Each woman was screened to detect persistent lesions and defined changes in ovarian volume. Morphological score and pulsatility index were recorded. SETTING--Ovarian screening clinic. SUBJECTS--1601 self referred women. INTERVENTIONS--Women with a positive screening result were recommended to have further investigations. MAIN OUTCOME MEASURES--Findings at surgery and histology of abnormal ovaries. Morphological score > or = 5 and pulsatility index < 1.0 at last scan. RESULTS--Women were aged 17 to 79 (mean 47) years; 959 (60%) were premenopausal, 469 (29%) were naturally postmenopausal, and 173 (11%) had had a hysterectomy. 157 women had a pedigree suggestive of the site specific ovarian cancer syndrome and 288 of multiple site cancers. 61 women had a positive screening result (3.8%, 95% confidence interval 2.9 to 4.9%), six of whom had primary ovarian cancer detected at surgery (five stage Ia, one stage III). Use of a high morphological score or a low pulsatility index increased the odds of finding ovarian cancer from 1:9 to about 2:5 (1:1 in the highest risk groups). Five interval cancers were reported (three ovarian and two peritoneal). Eight of the 11 cancers developed in women with pedigrees suggestive of inherited cancer. CONCLUSIONS--Transvaginal ultrasonography with colour flow imaging can effectively detect early ovarian cancer in women with a family history of the disease. The screening interval should be less than two years.     

Transvaginal colour flow imaging: a possible new screening technique for ovarian cancer.

OBJECTIVE--To assess whether changes in the intraovarian vasculature or blood flow impedance can be used to identify potentially malignant masses. DESIGN--Open, non-comparative prospective study. SETTING--Ovarian screening clinics at King''s College Hospital and the Hallam Medical Centre. SUBJECTS--50 Women selected on the basis of their medical history and the result of a previous transvaginal ultrasound scan. Thirty women (10 premenopausal (scan taken on days 1 to 8 of the menstrual cycle) and 20 postmenopausal) had normal ovaries, and 20 had at least one ovary with an abnormal morphology or volume, or both. INTERVENTIONS--Women with a positive result on screening were referred for laparotomy. MAIN OUTCOME MEASURES--Presence or absence of coloured areas (neovascularisation) and the pulsatility index within each ovary. The pulsatility index is a measure of the impedance to blood flow, a low value indicating decreased impedance and a high value increased impedance to blood flow. RESULTS--Two women with a positive result on screening had hydrosalpinges, 10 a benign tumour or a tumour-like condition, and eight primary ovarian cancers. No areas of neovascularisation were seen in the 30 women with morphologically normal ovaries and the two patients with hydrosalpinges; the pulsatility index ranged from 3.1 to 9.4. Similarly, nine patients (10 affected ovaries) with a non-malignant mass had no signs of neovascularisation and the pulsatility index varied from 3.2 to 7.0. One patient with bilateral dermoid cysts containing nests of thyroid-like cells had vascular changes and pulsatility index values of 0.4 and 0.8. Seven patients (eight ovaries) with primary ovarian cancer (one stage IV, four stage II, and two stage Ia) showed clear evidence of neovascularisation and pulsatility index values were from 0.3 to 1.0. One patient with an intraepithelial serous cystadenocarcinoma in a small ovary (less than 5 ml volume) had no signs of any vascular change and the pulsatility index was 5.5. CONCLUSION--Transvaginal colour flow imaging may be used to identify potentially malignant ovarian masses and help elucidate the early stages of tumorigenesis. The routine application of this technique may reduce the rate of false positive results of an ultrasonography based screening procedure.     

Prevalence screening for ovarian cancer in postmenopausal women by CA 125 measurement and ultrasonography.

OBJECTIVE--To assess the performance of the sequential combination of serum CA 125 measurement and ultrasonography in screening for ovarian cancer. DESIGN--The serum CA 125 concentration of each subject was determined and those with a concentration > or = 30 U/ml were recalled for abdominal ultrasonography. If ultrasonography gave abnormal results surgical investigation was arranged. Volunteers were followed up by annual postal questionnaire. SETTING--General practice, occupational health departments, ovarian cancer screening clinic. SUBJECTS--22,000 women volunteers who were postmenopausal and aged over 45 years. MAIN OUTCOME MEASURES--Apparent sensitivity, specificity, positive predictive value, years of cancer detected. RESULTS--41 women had a positive screening result and were investigated surgically. 11 had ovarian cancer (true positive result) and 30 had other disorders or no abnormality (false positive result). Of the 21,959 volunteers with a negative screening result, eight subsequently presented clinically with ovarian cancer (false negative result) and 21,951 had not developed ovarian cancer during follow up (apparent true negative result). The screening protocol achieved a specificity of 99.9%, a positive predictive value of 26.8%, and an apparent sensitivity of 78.6% and 57.9% at one year and two year follow up respectively. The estimated number of years of cancer detected by the prevalence screen was 1.4 years. CONCLUSIONS--This screening protocol is highly specific for ovarian cancer and can detect a substantial proportion of cases at a preclinical stage. Further investigation is required to determine the effect of the screening protocol on the ratio of early to late stage disease detected and on mortality from ovarian cancer.     

Knowledge about Cervical Cancer and Barriers of Screening Program among Women in Wufeng County,a High-Incidence Region of Cervical Cancer in China

Purpose

Cervical cancer screening is an effective method for reducing the incidence and mortality of cervical cancer, but the screening attendance rate in developing countries is far from satisfactory, especially in rural areas. Wufeng is a region of high cervical cancer incidence in China. This study aimed to investigate the issues that concern cervical cancer and screening and the factors that affect women’s willingness to undergo cervical cancer screening in the Wufeng area.

Participants and Methods

A cross-sectional survey of women was conducted to determine their knowledge about cervical cancer and screening, demographic characteristics and the barriers to screening.

Results

Women who were willing to undergo screenings had higher knowledge levels. “Anxious feeling once the disease was diagnosed” (47.6%), “No symptoms/discomfort” (34.1%) and “Do not know the benefits of cervical cancer screening” (13.4%) were the top three reasons for refusing cervical cancer screening. Women who were younger than 45 years old or who had lower incomes, positive family histories of cancer, secondary or higher levels of education, higher levels of knowledge and fewer barriers to screening were more willing to participate in cervical cancer screenings than women without these characteristics.

Conclusion

Efforts are needed to increase women’s knowledge about cervical cancer, especially the screening methods, and to improve their perceptions of the screening process for early detection to reduce cervical cancer incidence and mortality rates.     

Preneoplastic changes in ovarian tissues

OBJECTIVE: To test whether histologically normal epithelium within ovarian inclusion cysts and stroma exhibit changes in nuclear chromatin pattern that indicate the presence of occult ovarian lesions. STUDY DESIGN: Ovaries were collected from 10 low-risk women,from 7 high-risk women and from 3 women with ovarian cancer. Histologic sections were cut at 5 microm and hematoxylin and eosin stained. High-resolution images were recorded from the epithelium lining inclusion cysts and from the underlying stroma of ovaries from these 20 subjects. A total of 2860 epithelial nuclei and 3610 stromal nuclei were recorded. Karyometric features and nuclear abnormality were computed. Discriminant analyses and unsupervised learning algorithms defined deviations from normal that were designated "above threshold" and used to compute average nuclear abnormality of a second nuclear phenotype. RESULTS: Histologically normal epithelium from inclusion cysts of ovaries harboring a malignant lesion was shown to exhibit changes in the nuclear chromatin pattern that were statistically significant using quantitative image analysis procedures. Similar changes were seen in the inclusion cyst epithelia of high-risk ovaries. A subpopulation of cells representing a new phenotype was detected in the underlying stroma of women harboring a malignant ovarian lesion and in women at high risk of ovarian cancer. CONCLUSION: The karyometric changes observed in the epithelia lining inclusion cysts and in the underlying stroma of ovaries either with ovarian cancer or at high risk of ovarian cancer suggest the presence of preneoplastic changes in histologically normal tissue.     

Early detection of ovarian cancer: preliminary results of the Yale Early Detection Program.

Eighty-four women at high risk for ovarian cancer by having first-degree relatives with epithelial ovarian cancer participated in a newly established, early ovarian cancer detection program at Yale University. Participants were to be evaluated with physical examinations and circulating tumor markers at entry and every six months thereafter. Endovaginal ultrasound and color Doppler flow studies were to be performed at three and nine months following entry into the program. In addition, women were encouraged to follow American Cancer Society guidelines for mammography. Stool was checked for occult blood. Endometrial sampling was offered to post-menopausal women. No participant has developed an ovarian cancer since entering the program. One woman has been diagnosed to have breast cancer. False-positive levels of circulating tumor markers (CA 125, 4/84 [4.8 percent]; lipid-associated sialic acid in plasma, 13/84 [15.5 percent]; NB/70K, 4/84 [4.8 percent]; and urinary gonadotropin fragment, 1/65 [1.5 percent]) were observed on entry into the program. Low resistive indices (less than 0.5) were documented in 8/91 (8.8 percent) ovaries studied by the color Doppler flow technique. One participant underwent a laparotomy based on a false-positive endovaginal ultrasound examination. Tests now being employed in community practice have a high likelihood of being associated with false-positive results. Therapeutic interventions based on isolated abnormal tumor markers or ultrasound studies obtained from women with family histories of ovarian cancer may lead to inappropriate surgery. It is necessary for cancer centers to develop expertise in ovarian cancer detection techniques to advise physicians in their geographic areas appropriately about the significance of the abnormal screening test.     

Performance of Different Gastric Cancer Screening Methods in Korea: A Population-Based Study

Background

There is a lack of agreement on which gastric cancer screening method is the most effective in the general population. The present study compared the relative performance of upper-gastrointestinal series (UGIS) and endoscopy screening for gastric cancer.

Methods

A population-based study was conducted using the National Cancer Screening Program (NCSP) database. We analyzed data on 2,690,731 men and women in Korea who underwent either UGIS or endoscopy screening for gastric cancer between January 1, 2002 and December 31, 2005. Final gastric cancer diagnosis was ascertained through linkage with the Korean Central Cancer Registry. We calculated positivity rate, gastric cancer detection rate, interval cancer rate, sensitivity, specificity, and positive predictive value of UGIS and endoscopy screening.

Results

The positivity rates for UGIS and endoscopy screening were 39.7 and 42.1 per 1,000 screenings, respectively. Gastric cancer detection rates were 0.68 and 2.61 per 1,000 screenings, respectively. In total, 2,067 interval cancers occurred within 1 year of a negative UGIS screening result (rate, 1.17/1,000) and 1,083 after a negative endoscopy screening result (rate, 1.17/1,000). The sensitivity of UGIS and endoscopy screening to detect gastric cancer was 36.7 and 69.0%, respectively, and specificity was 96.1 and 96.0%. The sensitivity of endoscopy screening to detect localized gastric cancer was 65.7%, which was statistically significantly higher than that of UGIS screening.

Conclusion

Overall, endoscopy performed better than UGIS in the NCSP for gastric cancer. Further evaluation of the impact of these screening methods should take into account the corresponding costs and reduction in mortality.     

Early detection of ovarian cancer: background, rationale, and structure of the Yale Early Detection Program.

Ovarian cancer has received national attention as a highly virulent disease. Its lack of early warning symptoms and the failure to develop highly sensitive screening tests have led some physicians to recommend prophylactic oophorectomies to women with relatives who have had ovarian cancer. Others have recommended routine screening of otherwise normal women for CA 125, a circulating tumor marker, and ultrasound examinations. Each of these techniques is associated with substantial false-positive rates that could lead to unnecessary surgery. A review of epidemiologic data suggests that familial ovarian cancer kindreds are rare, but women with first-degree relatives who have had ovarian cancer have a significant risk themselves for developing ovarian cancer. In addition, women with a great number of ovulatory cycles are at an increased risk for the disease. Circulating tumor markers are frequently elevated in women with advanced ovarian cancer, but their value in early detection of ovarian cancer has yet to be established. Advances in endovaginal ultrasound and color Doppler flow technology have significantly improved our ability to assess pelvic organs. This article presents the background, rationale, and structure of the Yale Early Detection Program for ovarian cancer, whose goals are to identify the best techniques for diagnosing ovarian cancer in an early stage, to determine the frequency with which such tests should be employed, to assess false-positive results, and to identify women who might benefit from prophylactic oophorectomies.     

Effect of delays in primary care referral on survival of women with epithelial ovarian cancer: retrospective audit

ObjectiveTo examine referral pathways from primary care for patients with epithelial ovarian cancer and to identify factors related to survival at 18 months.DesignRetrospective review of patient notes.SettingGeneral practices and receiving hospitals within Mersey region.Subjects135 patients with epithelial ovarian cancer identified from an audit in the Mersey area between 1992 and 1994.Results105 (78%) women first presented to their general practitioner within four weeks of the onset of symptoms. 99 (73%) women were referred to hospital by their general practitioners within four weeks of presentation, and 95 (70%) were seen in hospital within two weeks of referral. Multivariate analysis with survival as the dependent variable identified age (odds ratio 0.96, 95% confidence interval 0.93 to 0.99) cancer stage III or more (0.15, 0.05 to 0.43), and non-specific symptoms (0.36, 0.14 to 0.89) as significant variables.ConclusionMost patients attended their general practitioner within four weeks and were referred within two weeks. No evidence was found that delays in referral or diagnosis adversely affected survival at 18 months. Stage of disease at surgery was the most important adverse factor. An effective screening programme is the most likely method to improve survival.

What is already known on this topic

Epithelial ovarian cancer is the most common gynaecological cancer in the United Kingdom75% of patients present with advanced incurable disease, and five year survival is 30%The Department of Health recommends that everyone suspected of having ovarian cancer should be seen within two weeks of referral by their general practitioner

What this study adds

78% of patients have had symptoms for less than 4 weeks when they present to general practice and are referred to hospital within four weeks of presentation70% of patients are seen in hospital within two weeks of the referralDelay by patients and general practitioners does not affect survival beyond 18 months     

Evaluation of proteomics-identified CCL18 and CXCL1 as circulating tumor markers for differential diagnosis between ovarian carcinomas and benign pelvic masses

A lack of sensitive and specific tumor markers for early diagnosis and treatment is a major cause for the high mortality rate of ovarian cancer. The purpose of this study was to identify potential proteomics-based biomarkers useful for the differential diagnosis between ovarian cancer and benign pelvic masses. Serum samples from 41 patients with ovarian cancer, 32 patients with benign pelvic masses, and 41 healthy female blood donors were examined, and proteomic profiling of the samples was assessed by surface-enhanced laser desorption/ionization time-of-flight (SELDI-TOF) mass spectroscopy (MS). A confirmatory study was also conducted with serum specimens from 58 patients with ovarian carcinoma, 37 patients with benign pelvic masses, and 48 healthy women. A classification tree was established using Biomarker Pattern Software. Six differentially expressed proteins (APP, CA 125, CCL18, CXCL1, IL-8, and ITIH4) were separated by high-performance liquid chromatography and identified by matrix-assisted laser desorption/ionization (MALDI)-MS/MS and database searches. Two of the proteins overexpressed in ovarian cancer patients, chemokine CC2 motif ligand 18 (CCL18) and chemokine CXC motif ligand 1 (CXCL1), were automatically selected in a multivariate predictive model. These two protein biomarkers were then validated and evaluated by enzyme-linked immunosorbent assay (ELISA) in 535 serum specimens (130 ovarian cancer, 64 benign ovarian masses, 36 lung cancer, 60 gastric cancer, 55 nasopharyngeal carcinoma, 48 hepatocellular carcinoma, and 142 healthy women). The combined use of CCL18 and CXCL1 as biomarkers for ovarian cancer had a sensitivity of 92% and a specificity of 97%. The multivariate ELISA analysis of the two putative markers in combination with CA 125 resulted in a sensitivity of 99% for healthy women and 94% for benign pelvic masses, and a specificity of 92% for both groups; these values were significantly higher than those obtained with CA 125 alone (p and lt;0.05). We conclude that serum CCL18 and CXCL1 are potentially useful as novel circulating tumor markers for the differential diagnosis between ovarian cancer and benign ovarian masses.     

Progress and challenges in screening for early detection of ovarian cancer

Ovarian cancer is characterize by few early symptoms, presentation at an advanced stage, and poor survival. As a result, it is the most frequent cause of death from gynecological cancer. During the last decade, a research effort has been directed toward improving outcomes for ovarian cancer by screening for preclinical, early stage disease using both imaging techniques and serum markers. Numerous biomarkers have shown potential in samples from clinically diagnosed ovarian cancer patients, but few have been thoroughly assessed in preclinical disease and screening. The most thoroughly investigated biomarker in ovarian cancer screening is CA125. Prospective studies have demonstrated that both CA125 and transvaginal ultrasound can detect a significant proportion of preclinical ovarian cancers, and refinements in interpretation of results have improved sensitivity and reduced the false-positive rate of screening. There is preliminary evidence that screening can improve survival, but the impact of screening on mortality from ovarian cancer is still unclear. Prospective studies of screening are in progress in both the general population and high-risk population, including the United Kingdom Collaborative Trial of Ovarian Cancer Screening (UKCTOCS), a randomized trial involving 200,000 postmenopausal women designed to document the impact of screening on mortality. Recent advances in technology for the study of the serum proteome offer exciting opportunities for the identification of novel biomarkers or patterns of markers that will have greater sensitivity and lead time for preclinical disease than CA125. Considerable interest and controversy has been generated by initial results utilizing surface-enhanced laser desorption/ionization (SELDI) in ovarian cancer. There are challenging issues related to the design of studies to evaluate SELDI and other proteomic technology, as well as the reproducibility, sensitivity, and specificity of this new technology. Large serum banks such as that assembled in UKCTOCS, which contain preclinical samples from patients who later developed ovarian cancer and other disorders, provide a unique resource for carefully designed studies of proteomic technology. There is a sound basis for optimism that further developments in serum proteomic analysis will provide powerful methods for screening in ovarian cancer and many other diseases.     

High-risk premenopausal women's experiences of undergoing prophylactic oophorectomy: a descriptive study

Women who are at increased risk of developing ovarian cancer because of their family history may need to make decisions about the medical management of their cancer risk--whether to have ovarian screening or undergo prophylactic surgery. This qualitative study explores the perceived physical and emotional implications of undergoing preventative surgery using data collected during interviews with 23 high-risk premenopausal women who had undergone prophylactic oophorectomy because of their family history of cancer. Despite the fact that all of these women regarded their decision to undergo surgery extremely positively, 20 women also described what they regarded as the costs of undergoing surgery. These included post-operative complications, the onset of menopausal symptoms, side effects of hormone replacement therapy, and negative effects on body image and gender identity. The perceived benefits of surgery were described as risk reduction, enabling one to fulfil family obligations, removing the need for gynecological screening, cessation of menstruation, and positive side effects of hormone replacement therapy. This study suggests there is a need to inform women about potential physical and emotional sequelae of oophorectomy prior to undergoing this procedure.     

Disagreement between Human Papillomavirus Assays: An Unexpected Challenge for the Choice of an Assay in Primary Cervical Screening

We aimed to determine the disagreement in primary cervical screening between four human papillomavirus assays: Hybrid Capture 2, cobas, CLART, and APTIMA. Material from 5,064 SurePath samples of women participating in routine cervical screening in Copenhagen, Denmark, was tested with the four assays. Positive agreement between the assays was measured as the conditional probability that the results of all compared assays were positive given that at least one assay returned a positive result. Of all 5,064 samples, 1,679 (33.2%) tested positive on at least one of the assays. Among these, 41% tested positive on all four. Agreement was lower in women aged ≥30 years (30%, vs. 49% at <30 years), in primary screening samples (29%, vs. 38% in follow-up samples), and in women with concurrent normal cytology (22%, vs. 68% with abnormal cytology). Among primary screening samples from women aged 30–65 years (n = 2,881), 23% tested positive on at least one assay, and 42 to 58% of these showed positive agreement on any compared pair of the assays. While 4% of primary screening samples showed abnormal cytology, 6 to 10% were discordant on any pair of assays. A literature review corroborated our findings of considerable disagreement between human papillomavirus assays. This suggested that the extent of disagreement in primary screening is neither population- nor storage media-specific, leaving assay design differences as the most probable cause. The substantially different selection of women testing positive on the various human papillomavirus assays represents an unexpected challenge for the choice of an assay in primary cervical screening, and for follow up of in particular HPV positive/cytology normal women.     

The validation of cervical cytology. Sensitivity, specificity and predictive values

Statistics and methods for the validation of the results of cytologic screening for cervical cancer and its precursors were examined. Many of the methods commonly used, including the calculation of sensitivity and specificity on raw data, contain flaws that undermine their conclusions. Using a large computerized database of 748,871 cytologic screenings of 277,842 women over a ten-year period, the value of screening was examined. Only subsequent histologic examinations within one year were accepted to validate positive initial cytologic diagnoses; only two subsequent cytologic screenings within the next three years were accepted to validate negative initial cytologic diagnoses that had not been followed by a histologic examination. Cases not meeting these criteria were excluded from the initial analysis. From these data, the predictive value of a negative cytologic examination was determined to be 99.8%; the predictive value of a positive cytologic examination was 73.4% for an initial diagnosis of mild-to-moderate dysplasia, 90.6% for a diagnosis of severe dysplasia/carcinoma in situ, 94.5% for a diagnosis of carcinoma in situ or microinvasive carcinoma and 95.5% for an initial diagnosis of invasive carcinoma. Cases with an initial "questionable" cytologic diagnosis had a positive predictive value of only 64.0%. Extrapolation from the validated cases to the entire screened population showed an overall sensitivity of 80% and a specificity of 99.4% for cytologic screening for cervical cancer. The sensitivity was slightly lower for mild and moderate dysplasia (78.1%) and slightly higher for carcinoma in situ and severe dysplasia (81.4%) and invasive carcinoma (82.3%).     

Mammographic screening and mortality from breast cancer: the Malm? mammographic screening trial.

STUDY OBJECTIVE--To determine whether mortality from breast cancer could be reduced by repeated mammographic screening. DESIGN--Birth year cohorts of city population separately randomised into study and control groups. SETTING--Screening clinic outside main hospital. PATIENTS--Women aged over 45; 21,088 invited for screening and 21,195 in control group. INTERVENTIONS--Women in the study group were invited to attend for mammographic screening at intervals of 18-24 months. Five rounds of screening were completed. Breast cancer was treated according to stage at diagnosis. END POINT--Mortality from breast cancer. MEASUREMENTS AND MAIN RESULTS--All women were followed up and classed at end point as alive without breast cancer, alive with breast cancer, dead from breast cancer, or dead from other causes. Cause of death was taken from national mortality registry and for patients with breast cancer was validated independently. Mean follow up was 8.8 years. Altogether 588 cases of breast cancer were diagnosed in the study group and 447 in the control group; 99 v 94 women died of all causes and 63 v 66 women died of breast cancer (no significant difference; relative risk 0.96 (95% confidence interval 0.68 to 1.35)). In the study group 29% more women aged less than 55 died of breast cancer (28 v 22; relative risk 1.29 (0.74 to 2.25)). More women in the study group died from breast cancer in the first seven years; after that the trend reversed, especially in women aged greater than or equal to 55 at entry. Overall, women in the study group aged greater than or equal to 55 had a 20% reduction in mortality from breast cancer (35 v 44; relative risk 0.79 (0.51 to 1.24)). OTHER FINDINGS--In the study group 100 (17%) cancers appeared in intervals between screenings and 107 (18%) in non-attenders; 51 of these women died from breast cancer. Cancers classed as stages II-IV comprised 33% (190/579) of cancers in the study group and 52% (231/443) in the control group. CONCLUSIONS--Invitation to mammographic screening may lead to reduced mortality from breast cancer, at least in women aged 55 or over.     

Risk of significant gynaecological pathology in women with ?glandular neoplasia on cervical cytology

A. Talaat, D. Brinkmann, J. Dhundee, Y. Hana, J. Bevan, R. Irvine, S. Bailey and R. Woolas
Risk of significant gynaecological pathology in women with ?glandular neoplasia on cervical cytology Objective: To review the risk of pre‐invasive and invasive gynaecological pathology in women referred with cervical cytology reporting ?glandular neoplasia. Methods: Review of the case notes of all women referred with cervical cytology reported as ?glandular neoplasia between January 1999 and December 2008 at two UK hospitals: Portsmouth Hospitals NHS Trust and Queen Mary’s Hospital Sidcup. The category of ‘borderline nuclear change in endocervical cells’, result code 8 according to the national health service cancer screening programme (NHSCSP), was excluded from the study. Results: A total of 200 women were identified using the hospitals’ pathology computer systems. Invasive carcinoma was found in 48 women (24%): 28 endocervical adenocarcinomas, eight squamous cell carcinomas (SCC), ten endometrial and two ovarian adenocarcinomas. Pre‐invasive neoplasia was found in 115 (57.5%), including 14 cervical glandular intraepithelial neoplasia (CGIN), 31 cervical intraepithelial neoplasia (CIN) grade 2/3 and 70 concomitant CGIN and CIN2/3. CIN1/HPV was found in 25, simple endometrial hyperplasia in three and no histological abnormality in three. Thirty‐four (70.8%) of 48 invasive carcinomas (of which 23 were endocervical adenocarcinomas) were in asymptomatic women investigated for abnormal cytology. Fourteen of 34 (41.4%) of those with ?glandular neoplasia thought to be endometrial were CGIN or CIN2/3. Colposcopic appearances were normal in 47.6% of women with pure cervical glandular neoplasia (adenocarcinoma or CGIN) compared with 12.8% with squamous cell lesions (CIN2/3 or SCC): P = 0.0001. Thus, colposcopy was more sensitive for detecting squamous cell abnormalities than their glandular counterparts. Although cervical adenocarcinomas are less amenable to prevention by screening than cervical SCC, in our study cervical cytology predominantly detected these abnormalities at their early asymptomatic stages. Conclusion: At least CIN2 was found in 81.5% in women referred with cervical cytology reporting ?glandular neoplasia. A thorough evaluation of the whole genital tract is needed if colposcopy is negative.     

Ovarian cancer and ovulation induction drugs--is there a link?

Screening for ovarian cancer in a group of women with induced ovulations was encouraged by recently reported controversies about a possible association between the use of ovulation induction drugs and the increased risk of ovarian carcinoma. Transvaginal color Doppler ultrasonography was applied in screening for early stage ovarian malignoma in 110 asymptomatic women who received an ovulation induction therapy for infertility. Already reported standard parameters for discriminating malignant from benign flows, such as resistance index RI < 0.40, pulsatility index PI < 1 and morphological score (borders, cyst quality, septate areas, papilla and ovarian tissue echogenicity) were used. Screening included 110 women and was carried out from April 1, 1198 to March 31, 1999. Seven examinees had abnormal ovarian findings. The finding spontaneously regressed in five of them, one underwent surgery for a persistent cyst with a benign pathohistologic diagnosis, and one was diagnosed with early stage ovarian malignoma. RI < 0.40 was reported in one patient (0.9%) with a morphologically suspect finding and a pathohistologically confirmed malignoma, PI < 1 was found in 40 subjects or 36.4%, while malignoma was demonstrated in one case alone. The results showed the advantage of RI over PI in discriminating malignant from benign structures. The association between the use of ovulation stimulation drugs and the increased risk of ovarian carcinoma remains unproved and also challenges new dilemmas. The paper cautions against undesirable, potentially serious long-term effects of the use of ovulation induction agents. Additional trials should therefore be performed including a long-term prospective follow-up of women with induced ovulations.     

Referral and experience with genetic testing among women with early onset breast cancer

The purpose of this study was to determine whether physicians refer women with early onset breast cancer for genetic testing for BRCA1 and BRCA2, and how women respond to being offered testing and use the results. A web-based survey was distributed to 1221 women with early onset breast cancer. The survey included 158 questions divided into the following sections: demographics, family history of cancer, medical history, treatment history, and experience with genetic testing. Of 551 women diagnosed since 1993 who responded to the survey (45.1%), less than half (45%, n = 246) had ever discussed genetic testing with their physician and/or been referred to see a genetic counselor. Women with a family history of cancer (53%) and Ashkenazi Jewish women (81%) were more likely to have been referred. Of those who had discussed testing, 60% had undergone or were interested in testing. Overall 92 women were tested and 19 (20.6%) of these tested positive for a deleterious BRCA1 or BRCA2 mutation. Fourteen (74%) who tested positive subsequently underwent prophylactic surgery. Satisfaction with counseling and the decision to be tested was high. Among women who were not offered testing, the fact that the test had not been offered by their physician (89%), and fear of discrimination (83%) were the two most frequently cited factors for lack of interest in testing. A substantial number of women are not being referred to genetic counseling and/or testing after a diagnosis of early onset breast cancer. Among those who were tested, there was high interest in prophylactic surgery after confirmation of a BRCA1/2 mutation.
