Abstract
OBJECTIVE To estimate the risk of primary epithelial ovarian cancer (EOC) and slow growing borderline or Type I and aggressive Type II EOC in postmenopausal women with adnexal abnormalities on ultrasound. METHODS This was a prospective cohort study in the ultrasound group of the UK Collaborative Trial of Ovarian Cancer Screening of postmenopausal women with ultrasound-detected abnormal adnexal (unilocular, multilocular, unilocular solid and multilocular solid, solid) morphology on their first scan. Women were followed up through the national cancer registries and by postal questionnaires. Absolute risks of EOC and borderline, Type I and Type II EOC within 3 years of initial scan were calculated. RESULTS Of 48 053 women who underwent ultrasound examination and had complete scan data, 4367 (9.1% (95% CI, 8.8-9.3%)) had abnormal adnexal morphology. Median follow-up was 7.09 (25(th) -75(th) centiles, 6.03-7.92) years. Forty-seven (32 borderline or Type I, 15 Type II) were diagnosed with EOC. The overall absolute risk of EOC associated with abnormal adnexal morphology was 1.08% (95% CI, 0.79-1.43%); for borderline and Type I it was 0.73% (95% CI, 0.5-1.03%); and for Type II it was 0.34% (95% CI, 0.33-0.79%). In the subgroup (n = 741) with solid elements (unilocular solid, multilocular solid and solid) overall absolute risk was 4.45% (95% CI, 3.08-6.20%), for borderline and Type I it was 3.1% (95% CI, 1.9-4.6%) and for Type II it was 1.3% (95% CI, 0.6-2.4%). 11 982 women had both ovaries visualized and normal annual scans throughout the 3-year follow-up period. In this group, no borderline or Type I and eight Type II cancers were diagnosed. CONCLUSION Asymptomatic postmenopausal women with ultrasound-detected adnexal abnormalities with solid elements have a 1 in 22 risk for EOC. Despite the higher prevalence of Type II EOC, the risk of borderline or Type I cancer in women with ultrasound abnormalities seems to be higher than does the risk of Type II cancer. This has important immediate implications for patients with incidental adnexal findings as well as for any future ultrasound-based screening.

The impact of local surface changes in Borneo on atmospheric composition at wider spatial scales: coastal processes, land-use change and air quality. Philos Trans R Soc Lond B Biol Sci 2012; 366:3210-24.

Abstract
We present results from the OP3 campaign in Sabah during 2008 that allow us to study the impact of local emission changes over Borneo on atmospheric composition at the regional and wider scale. OP3 constituent data provide an important constraint on model performance. Treatment of boundary layer processes is highlighted as an important area of model uncertainty. Model studies of land-use change confirm earlier work, indicating that further changes to intensive oil palm agriculture in South East Asia, and the tropics in general, could have important impacts on air quality, with the biggest factor being the concomitant changes in NO(x) emissions. With the model scenarios used here, local increases in ozone of around 50 per cent could occur. We also report measurements of short-lived brominated compounds around Sabah suggesting that oceanic (and, especially, coastal) emission sources dominate locally. The concentration of bromine in short-lived halocarbons measured at the surface during OP3 amounted to about 7 ppt, setting an upper limit on the amount of these species that can reach the lower stratosphere.

Abstract
OBJECTIVE To evaluate factors affecting uptake of risk-reducing salpingo-oophorectomy (RRSO) over time in women at high-risk of familial ovarian cancer. DESIGN Prospective observational cohort. SETTING Tertiary high-risk familial gynaecological cancer clinic. POPULATION/SAMPLE New clinic attendees between March 2004 and November 2009, fulfilling the high-risk criteria for the UK Familial Ovarian Cancer Screening Study. METHODS Risk management options discussed included RRSO and ovarian surveillance. Outcome data were analysed from a bespoke database. The competing risk method was used to model the cumulative incidence function (CIF) of RRSO over time, and the sub-hazard ratio (SHR) was used to assess the strength of the association of variables of interest with RRSO. Gray's test was used to evaluate the difference in CIF between two groups and multivariable competing risk regression analysis was used to model the cumulative probabilities of covariates on the CIF. RESULTS Of 1133 eligible women, 265 (21.4%) opted for RRSO and 868 (69.9%) chose screening. Women undergoing RRSO were older (49 years, interquartile range 12.2 years) than those preferring screening (43.4 years, interquartile range 11.9 years) (P < 0.0005). The CIF for RRSO at 5 years was 0.55 (95% CI 0.45-0.64) for BRCA1/2 carriers and 0.22 (95% CI 0.19-0.26) for women of unknown mutation status (P < 0.0001); 0.42 (95% CI 0.36-0.47) for postmenopausal women (P < 0.0001); 0.29 (95% CI 0.25-0.33) for parity ≥1 (P = 0.009) and 0.47 (95% CI 0.39-0.55) for a personal history of breast cancer (P < 0.0001). Variables of significance from the regression analysis were: a BRCA1/2 mutation (SHR 2.31, 95% CI 1.7-3.14), postmenopausal status (SHR 2.16, 95% CI 1.62-2.87)) and a personal history of breast cancer (SHR 1.5, 95% CI 1.09-2.06). CONCLUSIONS Decision-making is a complex process and women opt for surgery many years after initial risk assessment. BRCA carriers, postmenopausal women and women who had breast cancer are significantly more likely to opt for preventative surgery.

Abstract
OBJECTIVE To determine the accuracy of naked eye assessment of surgical margins after formalin fixation in vulval cancer in comparison with microscopic assessment. DESIGN Retrospective review. SETTING The Gynaecological Cancer Centre, St Bartholomew's Hospital, London, U.K. POPULATION Patients with primary vulval cancer who underwent surgery from 1997 to 2006. METHODS Histopathology reports were reviewed and data on surgical margins were analysed. After formalin fixation, pathologists analysed surgical margins and measured them with a ruler. This measurement was compared with microscopic measurement. Other clinicopathologic variables were also recorded and compared. MAIN OUTCOME MEASURE Comparison between macroscopic and microscopic measurement, and the relation to clinicopathological variables. RESULTS Naked eye assessment of surgical margins was within 2 mm of correlated microscopic measurement in 29 patients (Group 1). In ten patients the macroscopic measurement of clear margins was less than the microscopic (Group 2). In the remaining 11 cases (22%) naked eye observation overestimated the normal skin margins (Group 3). Seven patients from this group eventually fell into the unfavourable prognostic category of surgical margins <8 mm. The presence of LVSI was significantly more frequent in Group 3 than in the other two groups (p = 0.01). The difference between other variables of the study groups was statistically non-significant. CONCLUSION Our study demonstrates that naked eye assessment of surgical margins after formalin fixation is inaccurate and that surgical margins are often inadequate. We conclude that tumours with LVSI should be considered for a wider surgical excision.

Abstract
It is argued that isotope analysis of atmospheric non-methane hydrocarbons (NMHCs) and, in particular, the analysis of the deuterium/hydrogen (D/H) ratio is valuable because the dominant self-cleansing property of the troposphere is based on the OH radical which removes, e.g., CH4 and other alkanes by H-atom abstraction, which induces large kinetic isotope effects. The major obstacle in applying D/H isotope analysis to atmospheric NMHCs is not only the low abundance of D itself but, in particular, the low concentrations of NMHCs in the parts per trillion range. We show how a selection of NMHCs can be quantitatively separated from 300 L air samples together with CO2 as carrier gas matrix, by using high efficiency cryogenic traps. After diluting the extracted NMHC mixtures with hydrocarbon free air, and determining the mixing ratios, good agreement with original whole air sample analysis exists for alkanes and several halocarbons. For unsaturated hydrocarbons and some other halocarbons the extraction and recovery yield under the given conditions fell considerably, as a function of boiling point. Furthermore, the mixture of NMHCs in the CO2 matrix is proven to remain unchanged over several years when conveniently stored in glass ampoules. The 'extracts' or 'concentrates' of condensables extracted from larger air samples will enable the D/H isotope analysis of ultra trace gases in the atmosphere.

Abstract
The purpose of this study was to provide both a population estimate and a socio-economic and health profile of gay and bisexual men living with HIV/AIDS in a large Canadian urban centre. A random telephone survey was used to determine the number of men in the study area over the age of 20 identifying as gay or bisexual and to characterize their health and socio-economic status. Out of a total of 1,176 completed interviews, 300 males described themselves as gay or bisexual. Projecting this figure on recent census data we estimated the number of men identifying as gay or bisexual in this region of downtown Vancouver, BC, at 5,100. Among these men we found an HIV prevalence rate of 16%, with those who reported a positive serostatus being less likely to be employed full time and more likely to earn less than $20,000 per year. In terms of clinical characteristics, HIV-positive men had a median CD4 cell count of 397 cells/mm(3) and a median viral load of less than 500 copies/ml. Eighty-three per cent of the HIV-positive respondents were on antiretroviral therapy and the median number of drugs taken by these men was three. In summary, random surveys of populations affected by this epidemic are important for policy makers, clinicians and persons caring for those with HIV/AIDS as they paint a clearer picture of who is being affected and help to identify areas where increased services are needed.

Abstract
This study was undertaken to evaluate the life expectancy of gay and bisexual men in the West End of Vancouver, British Columbia during two time periods. Mortality data for males were obtained for the periods 1990 to 1992 and 1995 to 1997 and population estimates were obtained from the 1991 and 1996 Census. The proportion of the male population over 20 years of age estimated to be gay and bisexual was derived from a random telephone survey. Mortality patterns were assessed by comparing changes in life expectancy at age 20 years between the periods, and by examining the life expectancy lost attributed to HIV/AIDS. Between the periods there was 3.8 +/- 3.4 years increase in life expectancy among gay and bisexual men. At exact age 20 years, life expectancy increased from 37.0 +/- 3.5 years during the period 1990 to 1992 to 40.8 +/- 2.4 years during the period 1995 to 1997. The loss of life expectancy attributed to HIV/AIDS at this age was 13.8 +/- 3.9 during the first period and 9.8 +/- 3.6 years during the second period. This gain is most likely the result of the improved efficacy of antiretroviral therapies.

Abstract
The National Health Service Central Register (NHSCR) and direct follow-up were used to document ovarian and fallopian tube cancers in 22000 women from 1986 to 1993. Direct follow-up identified 47/49 cases (96%) and the NHSCR 38/49 (78%). NHSCR ascertainment was incomplete and direct follow-up provided additional information. These findings have implications for interpretation of national cancer statistics and for use of the NHSCR in research trials.

Abstract
Fallopian tube carcinoma can be histologically indistinguishable from and has a similar clinical behavior to epithelial ovarian carcinoma. However, it is considerably less common; only approximately 1000 cases have been recorded in the literature. In the prevalence screen of 22000 women participating in The Royal London Hospital, London, UK, ovarian cancer screening project, three cases of early stage primary fallopian tube carcinoma were diagnosed following the finding of an elevated serum level of the CA 125 antigen. The ratio of epithelial ovarian : tubal cancer developing in these postmenopausal volunteers was 6:1. This is 25-fold greater than the expected ratio. It is difficult to attribute this finding to population selection bias. However, it is possible that the screening test was particularly effective in detecting tubal carcinoma or that, in clinical practice, the true primary site of origin of some tumors classified as widely disseminated ovarian cancer is in the fallopian tube.

Abstract
OBJECTIVE To validate a risk of malignancy index incorporating menopausal status, serum CA 125 level and pelvic ultrasound features in the pre-operative diagnosis of ovarian cancer. DESIGN A retrospective observational study. SETTING Department of Obstetrics and Gynaecology, The Royal London Hospital. SUBJECTS One hundred and twenty-four women admitted consecutively to the gynaecology department for surgical exploration of an adnexal mass. MAIN OUTCOME MEASURES The sensitivities and specificities of menopausal status, serum CA 125 level and ultrasound features, in isolation and combined (the risk of malignancy index (RMI)), for diagnosing ovarian cancer. RESULTS Tested on a new population of women, the RMI retained the high sensitivity for diagnosing ovarian cancer seen in the original report describing its derivation. The specificity, however, was lower. The study confirmed that the RMI is more accurate than the individual criteria in diagnosing ovarian cancer, and was comparable with other scoring systems. CONCLUSIONS The risk of malignancy index is a simple scoring system for ovarian cancer. Application of the risk of malignancy index in clinical practice may provide a rational basis for specialist referral of patients with ovarian cancer before diagnostic surgery.

Abstract
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.

Abstract
Age, ultrasound score, menopausal status, a clinical impression score and serum CA 125 level were assessed to see how they could best distinguish between patients with benign (n = 101) and malignant (n = 42) pelvic masses. Each criteria used alone provided statistically significant discrimination. The most useful individual criteria were a serum CA 125 level of 30 U/ml (sensitivity 81%, specificity 75%) and an ultrasound score of 2 (sensitivity 71%, specificity 83%). Three criteria could be combined in a risk of malignancy index (RMI) which is simply calculated using the product of the serum CA 125 level (U/ml), the ultrasound scan result (expressed as a score of 0, 1 or 3) and the menopausal status (1 if premenopausal and 3 if postmenopausal). This index was statistically virtually as effective a discriminant between cancer and benign lesions as more formal methods. Using an RMI cut-off level of 200, the sensitivity was 85% and the specificity was 97%. Patients with an RMI score of greater than 200 had, on average, 42 times the background risk of cancer and those with a lower value 0.15 times the background risk.

Three criteria could be combined in a risk of malignancy index (RMI) which is simply calculated using the product of the serum CA 125 level (U/ml), the ultrasound scan result (expressed as a score of 0, 1 or 3) and the menopausal status (1 if premenopausal and 3 if postmenopausal). This index was statistically virtually as effective a discriminant between cancer and benign lesions as more formal methods. Using an RMI cut-off level of 200, the sensitivity was 85% and the specificity was 97%. Patients with an RMI score of greater than 200 had, on average, 42 times the background risk of cancer and those with a lower value 0.15 times the background risk.

Abstract
A questionnaire designed to investigate attitudes to prophylactic oophorectomy was sent to 2817 fellows and members of the Royal college of Obstetricians and Gynaecologists. A total of 1142 replies was received from those who performed regular sessions of gynaecological surgery. The number of respondents who said they would usually remove apparently normal ovaries at the time of abdominal hysterectomy from premenopausal women in age groups 35-39, 40-44, 45-49 and over 49 years was 4 (0.4%), 27 (2%), 234 (20%) and 585 (51%) respectively, and from postmenopausal women 974 (85%). The majority of respondents said that (i) they would prescribe hormone replacement therapy in oophorectomized premenopausal women (82%); (ii) they did not consider unilateral oophorectomy to have a role in prevention of ovarian cancer (84%); and (iii) they routinely discussed the question of prophylactic oophorectomy with their patients before operation (65%). Only 128 (11%) of the respondents believed that greater than or equal to 10% of ovarian cancers in the UK could be prevented by prophylactic oophorectomy at the time of operation for benign disease, and 505 (44%) would perform prophylactic oophorectomy as a primary surgical procedure in women who had a strong family history of ovarian cancer.

Abstract
1010 postmenopausal women were recruited for an ovarian cancer screening programme incorporating serum CA-125 measurement and vaginal examination as initial tests and real-time ultrasonography as a secondary procedure in selected cases. The normal range for serum CA-125 in postmenopausal women was established. The specificity for ovarian cancer of serum CA-125 measurement and vaginal examination were 97.0% and 97.3%, respectively. The combinations of serum CA-125 measurement with ultrasound and vaginal examination with ultrasound achieved specificities of 99.8% and 99.0%, respectively. 100% specificity was achieved by serum CA-125 measurement with vaginal examination and by the combination of all three tests. The findings indicate that no individual screening test has acceptable specificity for ovarian cancer in postmenopausal women. However, the combination of CA-125 measurement with ultrasound did achieve acceptable specificity and offers the most hope of a specific and sensitive method for early detection.

Abstract
There are no generally accepted criteria for the removal or conservation of the apparently normal ovary during surgery for other conditions. In this article the benefits and disadvantages of prophylactic oophorectomy are reviewed and a schema for clinical practice is suggested.

Abstract
Para-aortic lymphadenectomy is a procedure that has an undoubted place within the management spectrum of gynaecological malignancies. It should be performed in selected cases by trained gynaecological oncologists who are versed in the technique and in the management of potential complications. The removal and histological examination of nodal tissue remains the most accurate method of assessing the precise extent of disease spread. Its main value, therefore, is as part of a surgical staging procedure, which provides reliable survival information. However, it is still questionable whether treatment planning based on this knowledge, including modification of adjuvant therapy, results in improved survival figures. Until more data are available to clarify the degree of patient benefit, para-aortic lymphadenectomy is a technique that is more suitably practised in investigative oncological centres rather than on a widespread clinical basis.
