Age related trends in the incidence of endometrial cancer in South East England 1962-1997.

Important population demographic changes have occurred over the last 50 years in the UK. Birth rates have fallen, obesity rates have increased and there has been an increase in the use of reproductive hormones, factors which may influence the epidemiology of endometrial cancer. We analysed the age-related trends in the incidence of endometrial cancer in South East England between 1962 and 1997 to determine if there was a correlation with the population demographic changes over this time period. We undertook a retrospective review of systematically collected data, looking specifically at the change in overall incidence of endometrial cancer and the age-related incidence for each five year group from 25 to 85 + years. The overall incidence of endometrial cancer remained unchanged over the 35-year study period. In women aged 35-54 years there was a decrease in incidence of endometrial cancer and this was significant in the 40-45 year age group. The study also revealed a statistically significant increase in incidence of endometrial cancer in women aged over 65 years with a greater rate of increase in older women, particularly those aged over 85. Thus, there is evidence from this study of significant changes in the age-related incidence of endometrial cancer in the 35-year study period that may be explained by alterations in life style and behaviour. The increased incidence in women aged 85 and over have potential implications for the planning and provision of cancer services in the future.

Delayed diagnosis of cervical cancer in young women.

This study aims to determine whether women under 35 years presenting with cervical cancer experience delays between presentation and diagnosis. All women referred with cervical cancer to the gynaecological cancer centre for the North London Cancer Network from January 2002 to December 2004 were identified retrospectively. Clinical presentation and time interval from symptoms to diagnosis were compared between women under and women over 35 years. A total of 105 women were included. Median age at diagnosis was 45 years (range 23--88). Twenty-two women (19%) were under 35 years at presentation and 17 had persistent symptoms prior to diagnosis. Median time from initial presentation to diagnosis in this group was 9 months (range 3--24 months); significantly longer than in the older group (9 vs 2 months; p=0.0009). Although cervical cancer is relatively rare in young women, diagnosis should be considered in symptomatic women as delay can limit treatment options.

Total laparoscopic hysterectomy as a primary surgical treatment for endometrial cancer in morbidly obese women.

To evaluate the feasibility of total laparoscopic hysterectomy as the primary treatment for endometrial cancer in morbidly obese women, an audit was carried out during an 18-month period in a tertiary referral centre for gynaecological oncology. Four women who had laparoscopic surgery were compared with a similar cohort who had open surgery. The mean operating time was equivalent, without evidence of excess morbidity with the laparoscopic approach. However, inpatient stay was longer with open versus laparoscopic surgery (11.5 vs 4 days). Laparoscopic surgery is safe to use in morbidly obese women with endometrial cancer.

The surgical management of women with ovarian cancer in the south west of England.

The surgical management of epithelial ovarian cancer in the South West of England was studied in the two years 1997-1998 in order to determine the factors that influence the outcome of surgery and to provide a baseline from which to assess the effect of centralisation of cancer services. All hospitals in the South West region of England participating in the Regional Cancer Organisation's longitudinal study of outcomes in gynaecological malignancies are included. Six hundred and eighty-two patients with epithelial ovarian cancer were registered with the RCO in the two-year study period. Five hundred and ninety-five women were offered primary cytoreductive surgery of which 438 were said to be optimally cytoreduced. Applying multivariate models to analyse the outcome of surgery, older patients (OR = 0.82 per 5-year increase in age, P = 0.0003), patients treated in hospitals managing fewer than ten cases of ovarian cancer per year (OR = 1.92, P = 0.02) and patients with FIGO stage 3 (OR = 0.02, P < 0.0001) or 4 (OR = 0.002, P < 0.0001) disease were less likely to be optimally cytoreduced. Gynaecological oncologists were 2.06 times more likely to attain optimal cytoreduction when compared to general gynaecologists and this was statistically significant (P = 0.01). The results from this study support the argument that limiting surgery for ovarian malignancy to specialised surgeons improves the extent of cytoreductive surgery.

Patterns in the incidence of age-related ovarian cancer in South East England 1967-1996.

OBJECTIVE: To study the age-related trends in the incidence rates of ovarian cancer in South East England between 1967 and 1996. DESIGN: A retrospective review of systematically collected data on ovarian cancer in South East England. METHODS: Data were obtained from the Thames Cancer Registry on the numbers and rates per 100,000 population of ovarian cancer per five-year age group (0-85+) in the 30-year period from 1967 to 1996 from the 26 health authorities in the Thames region. Linear regression was performed to determine the changes in incidence rates of ovarian cancer per age group over time. MAIN OUTCOME MEASURES: The change in overall incidence of ovarian cancer in South East England, as well as the change in incidence of ovarian cancer in each five-year age groups (20-85+) in the 30-year study period. RESULTS: There was a strong positive correlation between ovarian cancer rates and year of diagnosis in women aged > or = 70 years, and this was particularly marked in women > 85 years of age. There was a negative correlation between rates and year of diagnosis in women aged 45-59 years. The analysis did not demonstrate a significant correlation between ovarian cancer rates and year of diagnosis in women < 44 years of age or women aged 60-69 years. CONCLUSIONS: There have been significant changes in the pattern of ovarian cancer incidence in South East England during the 30-year period studied. The observed changes in ovarian cancer incidence in younger women may, in part, be explained by known reproductive factors. The rise in ovarian cancer rates among the older age group is difficult to explain, but has important implications for the future planning and provision of cancer services.

Changes to the cytokine microenvironment in the genital tract mucosa of HIV+ women.

As previous studies have indicated that genital tract mucosal T cell function may be impaired in HIV infection, we investigated the T cell cytokine mRNA in the genital tract mucosa of HIV-infected women to determine if there are alterations in the cytokine profile which may explain the T cell impairment. The in situ hybridization technique was used to investigate the T helper-1 (Th1: IL-2, interferon-gamma (IFN-gamma)) and Th2 cytokine (IL-4, IL-5, IL-10) mRNA profile in cervical biopsies from 10 HIV+ and 10 HIV- subjects. Cervical intraepithelial neoplasia (CIN) and genital infection had previously been excluded and the distribution of immunocompetent cells within the cervical mucosa was known for each subject. Non-parametric tests were used to compare the optical density (OD) of cytokine mRNA in the HIV+ and HIV- groups. Comparisons were also made between peripheral CD4 lymphocyte counts, cervical CD4/CD8 T lymphocyte ratios and cytokine mRNA OD in HIV+ subjects. The HIV+ women had significantly higher mRNA OD for the Th2 cytokines IL-4, IL-5 and IL-10 than HIV women. There was also significantly lower IL-2 mRNA OD in the former group. HIV+ women had lower IFN-gamma mRNA than HIV- women, but the difference was not statistically significant. There was no correlation between cytokine mRNA OD and peripheral CD4 count or cervical CD4/CD8 ratio. The predominance of Th2 cytokines, which are immuno-inhibitory, in the cervical mucosa of HIV+ women may underlie the impaired cytotoxic potential observed in the CD8+ T lymphocytes and may contribute to the susceptibility of HIV-infected women to recurrent genital tract infections and cervical neoplasia.

Demographic, clinical and social factors associated with human immunodeficiency virus infection and other sexually transmitted diseases in a cohort of women from the United Kingdom and Ireland. MRC Collaborative Study of women with HIV.

BACKGROUND: Clinical experience suggests many women with HIV infection have experienced no other sexually transmitted diseases (STD). Our objective was to test the hypothesis that a substantial proportion of women with HIV infection in the United Kingdom and Ireland have experienced no other diagnosed STD and to describe the demographic, clinical and social factors associated with the occurrence of other STD in a cohort of HIV infected women. METHOD: Analysis of cross-sectional baseline data from a prospective study of 505 women with diagnosed HIV infection. The setting was 15 HIV treatment centres in the United Kingdom and Ireland. The main outcome measures were occurrence of other STD diagnosed for the first time before and after HIV diagnosis. Data were obtained from interview with women and clinic notes. We particularly focused on occurrence of gonorrhoea, chlamydia and trichomoniasis after HIV diagnosis, as these are the STD most likely to reflect recent unprotected sexual intercourse. RESULTS: The women were mainly infected via heterosexual sex (n = 304), and injection drug use (n = 174). 151 were black Africans. A total of 250 (49.5%) women reported never having been diagnosed with an STD apart from HIV, 255 (50.5%) women had ever experienced an STD besides HIV, including 109 (21.6%) who had their first other STD diagnosed after HIV. Twenty-five (5%) women reported having had chlamydia, gonorrhoea or trichomoniasis diagnosed for the first time after HIV diagnosis, possibly reflecting unprotected sexual intercourse since HIV diagnosis. In all 301 (60%) women reported having had sex with a man in the 6 months prior to entry to the study. Of these, 168 (58%) reported using condoms 'always', 66(23%) 'sometimes' and 56 (19%) 'never'. CONCLUSIONS: Half the women in this study reported having never experienced any other diagnosed STD besides HIV. However, after HIV diagnosis most women remain sexually active and at least 5% had an STD diagnosed which reflect unprotected sexual intercourse.

Do women with HIV infection consult with their GPs?

In a cohort of 106 HIV-positive women, 86 (81%) were registered with a general practitioner (GP) and 71 (83%) had a GP who was aware of their HIV status. GPs were primarily consulted for perceived non-HIV-related problems and prescriptions. This is encouraging. However, primary and secondary care services should aim to increase the proportions of HIV-positive individuals with access to primary care.

Cervical abnormality and sexually transmitted disease screening in human immunodeficiency virus-positive women.

OBJECTIVE: To determine the incidence of genital tract infections and cervical abnormalities in 185 human immunodeficiency virus (HIV)-positive outpatients with a view toward establishing an effective policy for gynecology screening. METHODS: Gynecology results were reviewed for 185 HIV-positive women seen as outpatients at the Royal Free Hospital in London. All subjects underwent screening for cervical abnormalities (smear and colposcopy) and sexually transmitted disease (STD) at 6-month intervals for 6 years. The STD prevalence was calculated, and the relationship between the occurrence of STDs and the demography and sexual lifestyle of the women was examined to determine whether these factors were predictive for women at risk for STDs. The incidence of cervical intraepithelial neoplasia (CIN) was determined. We reviewed the use of colposcopy in addition to cytology as a primary screening test to see whether it improved the detection rate of CIN. RESULTS: Sixty-five (35.1%) women had a history of previous STDs, and new STDs were detected in 18 women at their first visits. None were detected at subsequent visits. Sexual lifestyle details did not predict women at risk for STDs. Ninety-eight (53%) cervical smears were reported as normal at the first visit, but there was a 3.1% (95% confidence interval 0, 6.6) false-negative rate when compared with colposcopy and directed biopsy. Five of fifty women (10%) with CIN I had progressed to higher-grade lesions by 6-month follow-up. CONCLUSIONS: Given the low prevalence of STDs detected, except for initial screening at presentation, regular, repeat STD screening of HIV-positive women appears to be unnecessary. Because of the high incidence of cervical abnormalities, screening for cervical biopsy improved the detection rate of cervical abnormalities.

Access to medical care one year prior to diagnosis in 100 HIV-positive women.

BACKGROUND: Anonymous antenatal testing for HIV antibodies suggests that the majority of HIV-positive women in the UK remain undiagnosed. Primary care reaches the majority of the population and women present more often than men. Sexual health matters are frequently raised, so there is an opportunity to discuss concerns with respect to HIV. Women often present with advanced HIV disease and with antiviral treatments proving to be more effective, there is now an even greater incentive to diagnose HIV early. OBJECTIVE: We aimed to look at access to medical care 1 year prior to HIV diagnosis in 100 HIV-positive women and to establish whether a discussion regarding HIV was recalled. METHOD: The setting was an established clinic for HIV-positive women in the Royal Free Hospital, London. In a 6-month period a questionnaire was completed by 100 women with their clinic doctor. RESULTS: Women were young (mean age 31). Most (84%) were infected by heterosexual sex. Forty-six per cent of the women presented with symptomatic HIV or AIDS and 50% were black Africans, hence there is a large ethnic bias in this sample. General practice was accessed by 65% of the women 1 year prior to HIV diagnosis. Few (14%) women recalled a discussion concerning HIV. Secondary care settings such as gynaecology and general outpatients were also frequently attended, but again HIV was apparently rarely discussed. There was no significant difference when variables such as time since diagnosis, health care setting, or ethnic group were concerned with respect to recall of a discussion concerning HIV. CONCLUSIONS: Despite coming from 'high risk' groups or presenting with symptomatic disease in the year prior to HIV diagnosis, few women recalled discussing HIV in either primary or secondary care settings. As these sites were commonly accessed, we feel that doctors and other health care workers should be encouraged and trained to raise HIV more routinely in their consultations.

Women with HIV disease attending a London clinic.

OBJECTIVE: To examine ethnic, relationship, health, and mental health factors for a cohort of women with HIV infection attending an inner London clinic. DESIGN AND METHODS: Structured schedules were utilised to analyse ethnic group, family, and reproduction issues, mental and physical health for 100 women drawn consecutively from attenders at an inner London HIV clinic RESULTS: 51% of the women were non-ethnic minority groups and 49% were from ethnic groups. HIV testing was often as a result of symptoms or partner illness. One in five had disclosed their status to one person only or no one. Ethnic minority women were more likely to restrict disclosure. Forty seven per cent of the women had 100 children with more children reported in ethnic minority families; 28% of the children had been tested for HIV and five were confirmed HIV positive; 9% of children were born after HIV diagnosis. Nineteen women reported one or more termination of pregnancy, the majority before HIV diagnosis. Three quarters had a partner of whom 56 knew the partner's status. Women with HIV positive partners were more likely to have children. Women kept in ignorance of partner status were more likely to be ethnic minority women. Thirty two per cent had an AIDS diagnosis, diagnosed mostly in the UK. Medical and counselling service uptake was high. Gynaecological problems were common (49% had one or more problem) and 34% had at least one hospital admission. A wide range of counselling issues were recorded, with variations over time. Suicidal issues were relevant for 13% of women (69% ideation, 31% attempts). Significant life events were noted for many women with allied coping demands. CONCLUSIONS: There are a wide range of issues for women with HIV and systematic differences between ethnic and non-ethnic women and those with or without children.

Infertility among human immunodeficiency virus-positive women: incidence and treatment dilemmas.

The increasing demand for fertility advice among human immunodeficiency virus (HIV)-positive women under our care led us to review the incidence of infertility and the ethical problems associated with its management. All HIV-positive women who attended the HIV outpatients clinic from October 1990 to the end of January 1996 were studied. The main outcome measures were: the number of women undergoing infertility investigations before and after HIV diagnosis, their demographic and social details, and the outcome of these investigations. Most of the 183 women studied were in their reproductive years (mean age 32.7 +/- 6.7 years). Nine women had undergone infertility investigations, and/or treatment before HIV diagnosis, three of whom were diagnosed with HIV during routine testing prior to IVF treatment. Six declined further infertility treatment after discovering their HIV status. Eight women have undergone infertility investigations after HIV diagnosis but none have achieved pregnancy to date. Management decisions may have been hampered by ethical uncertainties in several cases. In conclusion therefore, as requests for infertility treatment from HIV-infected women occur and may become more common as the prevalence of HIV infection in women continues to rise, the ethical issues associated with the management of this problem demand urgent attention so that clear guidelines are available to aid treatment decisions.

The distribution of immunocompetent cells in the genital tract of HIV-positive women.

OBJECTIVE: To study the distribution of immunocompetent cells in the female lower genital tract and to determine whether it is altered in HIV infection. METHODS: Colposcopically directed cervical biopsies were taken in the premenstrual phase of 10 HIV-positive women with sexually acquired infection, and matched HIV-negative controls. Peripheral blood was collected from the HIV-infected group for immune studies. Histological, immunohistochemical and double immunofluorescence techniques were applied to the biopsies to reveal immunocompetent cell distribution. Comparisons were made between the immune cell populations in the cervix in the HIV-positive and negative groups, and between the cervix and peripheral blood in the HIV-positive group. RESULTS: Cervical biopsies from HIV-positive women had significantly reduced Langerhans and plasma cell counts in the submucosa, but increased T lymphocyte counts compared with the HIV-negative group. There was an increase in CD8+ lymphocyte numbers in cervical biopsies of HIV-positive women, causing an inversion of the CD4/CD8 ratio. The majority of these CD8+ cells were 'memory' (CD45RO+) cells, with reduced proportions expressing perforin (cytoplasmic cytolytic granules) and TIA-1 (cytolytic granule-associated protein). Natural killer (CD57) cell markers were not detected. The levels of CD8+ cells expressing Bcl-2 (a gene product inhibiting cell apoptosis) in HIV-positive women with relatively high peripheral CD4 lymphocyte cell counts was higher than in HIV-negative women, but these levels fell with declining CD4 lymphocyte counts (< 300 x 10(6)/1). The reduction in CD4/CD8 ratio in the cervix occurred even with relatively high peripheral CD4 counts. CONCLUSIONS: HIV disease is associated with alterations in the proportions of immunocompetent cells in the cervix. There is an increase in CD8+ T-lymphocytes and evidence of reduced cytolytic capacity; thus, CD8+ cells may lack the ability to respond to viral infection. Reduction in Langerhans' and plasma cells may reflect loss of signals from CD4+ T cells. These findings may, in part, explain why HIV-infected women are susceptible to recurrent fungal and viral infections, even when peripheral immune function is intact. Further studies of immune cell function are urgently required to further elucidate these findings.
