Mid‐trimester soft markers have been linked with Down syndrome and other aneuploidies. There are many other prenatal screening tests available with better detection rates for Down syndrome than the mid‐trimester ultrasound. Many patients confronted with the diagnosis of a soft marker become anxious and may request a diagnostic test (amniocentesis) despite the associated risk of miscarriage. This is also despite the fact that most fetuses with an isolated soft marker are chromosomally normal. The management of a pregnancy with a soft marker must therefore be planned in a manner designed to minimize patient anxiety. Likelihood ratios can be used to modify a patient’s ‘prior risk’ (based on age or prior screening tests) and create a new risk. This calculation may help identify a subset of patients suitable for further investigation. It has been proposed that ‘negative’ likelihood ratios can be used to reduce a patient’s risk if no soft marker is found at a mid‐trimester ultrasound. There remain concerns about this approach and further research is required before this approach enters common practice. The published work surrounding the management of thickened nuchal fold, echogenic bowel, shortened femur, shortened humerus, pyelectasis (renal pelvis dilatation) and hypoplastic nasal bone is reviewed. Each soft marker has different associations and individual management plans for each of these soft markers are presented. Although isolated single umbilical artery is not usually considered a soft marker of aneuploidy, a management plan for this common finding is also included.  相似文献

Echogenic intracardiac focus and choroid plexus cysts are common findings at the midtrimester ultrasound. These findings have been linked with an increased risk of Down syndrome and trisomy 18. Most fetuses with these findings will, however, not have chromosomal abnormalities, especially when these findings are isolated. Patients experience considerable anxiety when informed of these findings and require extensive counselling in order to minimize anxiety not only about aneuploidy but also about the structure and development of the heart and brain. Although early studies showed an association with aneuploidies, several recent studies have cast doubt on this association. Many of the early studies were carried out in high‐risk populations or in populations that had not had the benefit of other screening tests. Many Australian and New Zealand patients will access screening tests designed to detect these aneuploidies before presenting for a midtrimester ultrasound. Patients who have been screened by nuchal translucency, maternal serum screening or some combination of the two will already have had most cases of Down syndrome and trisomy 18 detected, and any soft marker found will almost certainly be a false positive. It is time to rethink the management of these markers. Recent evidence indicates that if these markers are found in isolation in an otherwise low‐risk pregnancy, then there is minimal or no increase in the risk of Down syndrome or trisomy 18: these markers should be considered normal variants.The Australian Association of Obstetrical and Gynaecological Ultrasonologists consensus statement on these markers is included.  相似文献

It is unclear whether a woman's age influences her risk of cervical intraepithelial neoplasia grade 3 or worse (CIN3+) upon detection of HPV. A large change in risk as women age would influence vaccination and screening policies. Among 972,029 women age 30–64 undergoing screening with Pap and HPV testing (Hybrid Capture 2, Qiagen, Germantown, MD) at Kaiser Permanente Northern California (KPNC), we calculated age‐specific 5‐year CIN3+ risks among women with HPV infections detected at enrollment, and among women with “newly detected” HPV infections at their second screening visit. Women (57,899, 6.0%) had an enrollment HPV infection. Among the women testing HPV negative at enrollment with a second screening visit, 16,724 (3.3%) had a newly detected HPV infection at their second visit. Both enrollment and newly detected HPV rates declined with age (p < 0.001). Women with enrollment versus newly detected HPV infection had higher 5‐year CIN3+ risks: 8.5% versus 3.9%, (p < 0.0001). Risks did not increase with age but declined slightly from 30–34 years to 60–64 years: 9.4% versus 7.4% (p = 0.017) for enrollment HPV and 5.1% versus 3.5% (p = 0.014) for newly detected HPV. Among women age 30–64 in an established screening program, women with newly detected HPV infections were at lower risk than women with enrollment infections, suggesting reduced benefit vaccinating women at older ages. Although the rates of HPV infection declined dramatically with age, the subsequent CIN3+ risks associated with HPV infection declined only slightly. The CIN3+ risks among older women are sufficiently elevated to warrant continued screening through age 65.  相似文献

In spite of the success of cervical cytology as a cancer-screening tool, it has important limitations, and human papillomavirus (HPV) testing may be valuable in future screening. The majority of women in screened populations, who test HPV positive, will have a concurrent normal smear, and we need more information about the risk for subsequent high-grade cervical lesions in these women. We examined 8,656 younger women (22-32 years old) and 1,578 older women (40-50 years old) who were followed for development of cervical neoplasia (cytology and/or histology) through the Danish Pathology Data Bank. We estimated the proportion of women developing cervical lesions of different types before a given time point as a function of time. Among women with normal cytology and positive high-risk Hybrid Capture 2 (HC2) test, 17.7% and 24.5% of younger and older women, respectively, had a subsequent abnormal Pap smear within 5 years. The risk of CIN3 or cancer within 10 years among younger women with positive HC2 test was 13.6% (10.9-16.2) and 21.2% (2.7-36.1) among older women. An analysis among younger women also being HC2-positive 2 years before baseline showed a subsequent 10-year risk of > or =CIN3 of 18% (14.6-21.5). Among older women where HPV may be added to general screening, the estimated absolute risk of > or =CIN3 in HC2-positive women was more than 20% within 10 years. These results indicate that even a single positive HPV test in cytologically negative women is substantially predictive of high-grade CIN and suggest that HC2 testing can help stratify women into different risk categories.  相似文献

BACKGROUND: Tamoxifen-treated breast carcinoma survivors are at elevated risk of endometrial carcinoma. Whether to recommend annual surveillance for uterine abnormalities in this population is currently under debate. METHODS: This study was a cross-sectional, community-based investigation of tamoxifen use and the frequency of surveillance for endometrial carcinomas in 541 women with breast carcinoma. Study participants whose breast carcinoma was diagnosed in 1994 were interviewed in 1998. Data were collected from a telephone interview and from a cancer registry record. Tests for uterine abnormalities, based on participant reports of endometrial biopsy and transvaginal ultrasound, were categorized according to frequency. Testing for uterine abnormalities was defined as irregular if women reported tests once every 3 years, on average, and as regular, if they reported annual tests. RESULTS: Forty-nine percent of respondents were current tamoxifen users, 12% were former tamoxifen users, and 39% reported never taking tamoxifen. Of respondents with a uterus (n = 385), 19% reported irregular and 30% regular testing for uterine abnormalities after their breast carcinoma diagnosis. Respondents more frequently reported transvaginal ultrasound (37%) than endometrial biopsy (29%). Women 65 years of age and older were significantly less likely to report regular surveillance for uterine abnormalities (16%) than those younger than 65 years (35%). Current tamoxifen users more frequently reported regular surveillance (43%) than either former (35%) or never tamoxifen users (15%). Multivariable analyses showed tamoxifen users were more likely to have regular (odds ratio [OR], 9.8; 95% confidence interval [CI], 4.4-21.8) or to have irregular testing for uterine abnormalities (OR, 3.9; 95% CI, 1.9-8.1) compared with women who never used tamoxifen, after adjustment for age, number of recent gynecologic visits, and gynecologic symptoms. CONCLUSIONS: The results of the current study indicate that half of the breast carcinoma survivors in this population were tested for uterine abnormalities. Although at increased risk, 38% of tamoxifen users never had a test. Clear guidelines need to be established for the type and frequency of testing for uterine abnormalities among tamoxifen-treated breast carcinoma patients.  相似文献

Accurate pregnancy dating is vital to obstetric management. However, first trimester fetal charts commonly used in Australia rely on data reported more than three decades ago. This study reports first trimester dating and growth charts for crown‐rump length between 5 and 14 weeks of gestation and biparietal diameter between 9 and 14 weeks of gestation on an Australia population using modern real‐time ultrasound equipment. All consenting eligible women attending a large Sydney clinic for first trimester ultrasound between March 2005 and December 2006 were recruited. Measurements were carried out to Australasian Society for Ultrasound in Medicine standard protocols. Statistical analyses were undertaken using polynomial regression models and thorough diagnostic checks made. Overall 396 eligible women consented to the study, with 268 between 9 and 14 weeks of gestation. The average participant age was 34 years (range 22–45 years), 371 and all yielded valid biometry measurements. Equations, means and 90% reference intervals for crown‐rump length measurements and biparietal diameter measurements were derived using polynomial regression models. Thorough residual and diagnostic checks were made. Once validated by others, we believe they will warrant consideration for use by Australasian Society for Ultrasound in Medicine.  相似文献

Lynch syndrome/hereditary nonpolyposis colorectal cancer (HNPCC) is an autosomal dominant inherited cancer susceptibility syndrome caused by a germline mutation in one of the deoxyribonucleic acid (DNA) mismatch repair genes. It is associated with early onset of cancer (age younger than 50 years) and the development of multiple cancer types, particularly colon and endometrial cancer. Women with Lynch syndrome have a 40-60% risk of endometrial cancer, which equals or exceeds their risk of colorectal cancer. In addition, they have a 12% risk of ovarian cancer. Despite limited information on the efficacy of surveillance in reducing endometrial and ovarian cancer risk in women with Lynch syndrome, the current gynecologic cancer screening guidelines include annual endometrial sampling and transvaginal ultrasonography beginning at age 30-35 years. In addition, risk-reducing surgery consisting of prophylactic hysterectomy and bilateral salpingooophorectomy should be offered to women aged 35 years or older who do not wish to preserve their fertility.  相似文献

Cervical cancer mortality in Chile is four times higher than in developed countries. We compared the accuracy of human papillomavirus (HPV) DNA testing and conventional Papanicolaou (Pap) testing to detect prevalent precancerous and cancerous lesions in the routine clinical practice of the public health system. Women aged 25 years and older residing in the area covered by three primary care centers of Santiago, Chile, were invited to participate. Eligible women received both HPV DNA (Hybrid Capture 2) and Pap testing. Women positive by either test (Pap: ASCUS+, HC2: RLU/CO ≥1.0) underwent colposcopy and biopsy, as did a sample of double‐negative women with an abnormal cervix at visual inspection or with risk factors for cervical lesions. Crude and verification bias‐corrected sensitivities and specificities were estimated. In total, 8,265 women (98.8% of eligible) had complete screening results. Of these, 10.7% were HPV positive, 1.7% were Pap positive and 1.1% were positive by both tests. In all, 931 (11.3%) women were screen‐positive, of whom 94.3% attended colposcopy. Additionally, 295 control women were invited for colposcopy, of whom 78% attended. In all, 42 CIN2, 45 CIN3 and 9 cancers were identified. Verification bias‐corrected sensitivity for CIN2+ (95% confidence interval) was 92.7% (84.4–96.8) for HPV and 22.1% (16.4–29.2) for Pap; corresponding specificities were 92.0% (91.4–92.6) and 98.9% (98.7–99.0). In conclusion, in routine clinical practice in a developing country, HPV testing was four times more sensitive for CIN2+ than Pap testing, identifying three times more CIN2+ lesions; HPV testing was easily implemented in our established cervical cancer prevention program.  相似文献

The possible association between prenatal factors and breast cancer has been discussed for more than a decade. Birth weight has been used commonly as a proxy measure for intrauterine growth. Whereas some previous studies have found support for an association between birth weight and breast cancer, others have been inconclusive or found no association. We investigated the relationship between birth weight and risk of female breast cancer in a cohort of 106,504 Danish women. Birth weights were obtained from school health records on girls born between 1930-1975. Information on breast cancer came from linking the cohort with the Danish Cancer Registry and the Danish Breast Cancer Cooperative Groups Registry. A total of 2,334 cases of primary breast cancer were diagnosed in the cohort during 3,255,549 person-years of follow-up among women with birth weight between 500-6,000 g. Of these, 922 (40%) were diagnosed with primary breast cancer at the age of 50 years or older. A significant association between birth weight and breast cancer was found equivalent to an increase in risk of 9% per 1,000 g increase in birth weight (95% CI 2-17). The increase was observed for all age groups, representing both pre- and post-menopausal women, and irrespective of tumor characteristics. Adjustment for age at first birth and parity did not influence the results. Birth weight is positively associated with risk of breast cancer, indicating that prenatal factors are important in the etiology of breast cancer.  相似文献

To examine attitudes toward childbearing and prenatal genetic testing among individuals at risk for Lynch Syndrome (LS), the most common type of hereditary colorectal cancer. Individuals undergoing clinical genetic testing for mismatch repair (MMR) gene mutations completed written questionnaires before and after testing. 161 of 192 (84%) eligible individuals participated in the study. Mean age was 46 years (range 20–75), 71% were female, 53% had a personal diagnosis of cancer, and 68% had children. Eighty percent worried about their children’s risk for developing cancer; however only 9% reported their decision to have children was affected by their family history of cancer. When asked whether providing prenatal testing to carriers of MMR gene mutations was ethical, 66% (86/130) of respondents agreed/strongly agreed, 25% (32) were neutral and 9% (12) disagreed/strongly disagreed. Of 48 individuals planning to have children in the future, 57% (27) intended to have children regardless of their genetic test result. If found to carry a MMR gene mutation that confirmed LS, 42% (20) would consider prenatal testing for a future pregnancy and 20% (7/35) of women would consider having children earlier in order to have prophylactic surgery to reduce their risk for gynecologic cancers. Individuals undergoing genetic testing for LS may utilize test results to make reproductive decisions. Clinicians should be prepared to discuss options of reproductive genetic technologies during counseling of LS patients of childbearing age.  相似文献

BACKGROUND: A synthetic estrogen, diethylstilbestrol (DES), was widely prescribed to pregnant women during the 1950s and 1960s but was later discovered to be associated with an increased risk of clear-cell carcinoma of the vagina and cervix in female offspring. DES has not been linked to other cancers in female offspring, but studies of other prenatal factors such as twin gestation and pre-eclampsia have indicated that in-utero estrogen levels may influence breast cancer risk. We evaluated the relation of in-utero DES exposure to the risk of adult breast cancer.METHODS: A cohort of 4821 exposed women and 2095 unexposed women, most of whom were first identified in the mid-1970s, were followed by mailed questionnaires for an average of 19 years. Reported cancer outcomes were validated by medical record review. Breast cancer incidence in DES-exposed daughters was compared with cancer incidence in unexposed daughters with use of Poisson regression analysis, adjusting for year of birth, age at menarche, age at first birth, and number of births.FINDINGS: The rate ratio for incidence of invasive breast cancer in exposed versus unexposed women was 1.4 (95% confidence interval (CI) = 0.7–2.6). DES exposure was not associated with an increased risk of breast cancer in women under 40 years, but among women aged 40 and older the rate ratio was 2.5 (95% CI = 1.0–6.3). The rate ratio for the association of DES exposure with estrogen receptor-positive tumors was 1.9 (95% CI = 0.8–4.5).INTERPRETATION: While not statistically significant, the overall 40% excess risk, arising exclusively from the subset of estrogen receptor-positive cases, raises a concern calling for continued investigation.  相似文献

Cervical cancer is caused by human papillomavirus (HPV) and is the most common cancer among Mexican women, but no population-based studies have reported the prevalence and determinants of HPV infection in Mexico. A population-based study was carried out between 1996 and 1999, based on an age-stratified random sample of 1,340 women with normal cytologic diagnoses from 33 municipalities of Morelos State, Mexico. The prevalence of cervical HPV DNA was determined by reverse line blot strip assay to detect 17 cancer-associated and 10 non-cancer-associated HPV types. Two peaks of HPV DNA prevalence were observed. A first peak of 16.7% was observed in the age group under 25 years. HPV DNA prevalence declined to 3.7% in the age group 35-44 years, then increased progressively to 23% among women 65 years and older. Cancer-associated HPV types were the most common in all age groups; non-cancer-associated HPV types were rare in the young and became more common linearly with age. Twenty-four types of HPV were detected; HPV 16, HPV 53, HPV 31 and HPV 18 were the most common, but none was present in more than 1.7% of subjects. The main determinant of infection with both cancer-associated and non-cancer-associated HPV types was the number of sexual partners in all age groups. Less-educated women were at an increased risk of infection with cancer-associated but not with non-cancer-associated HPV types; low socioeconomic status was associated with detection of non-cancer-associated HPV types. Among young women an increasing number of pregnancies was associated with lower HPV detection and among older women low socioeconomic status was related to increased HPV detection, particularly for the age group 35-54 years. Among women with cancer-associated HPV types, there was a higher intensity of polymerase chain reaction signal in younger than in older age groups (p < 0.001). We present additional evidence for the sexually transmitted nature of HPV infection, regardless of age group and HPV type. We confirm previous findings of a second peak of high-risk HPV infections in postmenopausal women, in this case with a clear predominance of cancer-associated HPV types. In populations with this pattern, which can be related to reactivation of latent HPV infections or high previous exposure in older women, screening with HPV testing can have a reduced specificity among older women if proper cut-off points for HPV positivity are not used. Longitudinal studies of immune responses to HPV infection in different age groups are warranted.  相似文献

From 2015, Norway has implemented high-risk human papilloma virus (hrHPV) testing in primary screening for cervical cancer. Women aged 34–69 years, living in four counties, have been pseudo-randomly assigned (1:1 randomization) to either hrHPV testing every 5 years (followed by cytology if hrHPV is positive), or cytology testing every 3 years (followed by hrHPV testing if low-grade cytology is detected). We compared anxiety and depression scores among participants by screening arm and results. In total, 1,008 women answered a structured questionnaire that included the validated Patient Health Questionnaire-4 (PHQ-4). The Relative Risk Ratio (RRR) of mild vs. normal anxiety and depression scores, and moderate/severe vs. normal anxiety and depression scores, were estimated by multinomial logistic regression with 95% confidence intervals (95% CIs). Compared to women who were screened with cytology, women randomized to hrHPV testing were not more likely to have mild anxiety and depression scores (RRR 0.96, CI 0.70–1.31) nor more likely to have moderate/severe anxiety and depression scores (RRR 1.14, CI 0.65–2.02). Women with five different combinations of abnormal screening test results were not more likely to have mild or moderate/severe vs. normal anxiety and depression scores than women with normal screening results. The likelihood of having abnormal long-term (4–24 months after the screening) anxiety or depression scores among women 34 years and older was not affected by screening method or screening results. The results of our study suggest that a change to hrHPV testing in primary screening would not increase psychological distress among participants.  相似文献

The relationship of gestational trophoblastic disease (GTD) to parental age was evaluated in a case-control study of 132 women with hydatidiform mole (108) or choriocarcinoma (24) and 304 control subjects hospitalized for normal deliveries. Cases and controls were recruited in Lombardy (Northern Italy), and all were white and Italian. Compared to the risk of developing trophoblastic tumors in women 21-35 years old, the risk of developing trophoblastic tumors was elevated both in younger [less than or equal to 20 yr old, relative risk (RR) = 1.4, with 95% confidence interval (Cl) of 0.7-2.8] and in older subjects, RR being 1.2 (95% Cl 0.7-2.8) and 5.2 (95% Cl 2.2-12.3) for women 36-40 years old and over 40, respectively. The risk estimates for the last two categories were reduced to 0.7 (with 95% Cl of 0.3-1.9) and 2.5 (with 95% Cl of 0.7-8.9) when adjustment was made for paternal age by means of the Mantel-Haenszel procedure. Higher paternal age also was associated with GTD: Women whose husbands were 41-45 years old and over 45 had RR of 1.6 (with 95% Cl = 0.7-3.7) and 4.9 (with 95% Cl = 2.2-11.1), respectively, compared to women married to men less than 40 years old. These risk estimates were practically unchanged when adjustment was made for the woman's age. Examination of the effects of parental and maternal ages suggests that the highest risk estimate was observed when both parents were older. The findings of the present study were consistent with increased risk in the youngest maternal age group and confirm that older maternal age is associated with increased risk of GTD. Furthermore, showing a strong, independent effect of paternal age, they give epidemiologic support to the cytogenetic evidence of an androgenetic role in the origin of GTD.  相似文献

BACKGROUND: Few studies have investigated the association between reproductive factors and the risk of breast carcinoma among African-American women. The authors assessed whether the number of full-term pregnancies, age at first full-term pregnancy, and total duration of breastfeeding were associated with similar relative risk estimates in white and African-American women in a large multicenter, population-based case-control study of breast carcinoma. METHODS: Case patients were 4567 women (2950 white women and 1617 African-American women) ages 35-64 years with newly diagnosed invasive breast carcinoma between 1994 and 1998. Control patients were 4668 women (3012 white women and 1656 African-American women) who were identified by random-digit dialing and were frequency matched to case patients according to study center, race, and age. Adjusted odds ratios and 95% confidence intervals were estimated using unconditional logistic regression. RESULTS: For white women, the reduction in risk of breast carcinoma per full-term pregnancy was 13% among younger women (ages 35-49 years) and 10% among older women (ages 50-64 years). The corresponding risk reductions for African-American women were 10% and 6%, respectively. Risk decreased significantly with increasing number of full-term pregnancies for both races and both age categories. Duration of lactation was inversely associated with breast carcinoma risk among younger parous white (trend P = 0.0001) and African-American (trend P = 0.01) women. African-American women tended to have more children compared with white women, but parity rates were lower in younger women than in older women in both racial groups. However, breastfeeding was substantially more common in young white women than in young African-American women. CONCLUSIONS: Overall, parity and lactation had similar effects on breast carcinoma risk in white and African-American women. If younger African-American women now are giving birth to fewer children than in the past, without a substantial increase in breastfeeding, breast carcinoma rates may continue to increase at a more rapid rate among these women compared with white women.  相似文献

BackgroundWe evaluated the contribution of ultrasound (US) in detecting breast cancer in women with dense breasts and negative mammograms.Methods9157 (35.8%) of 25,572 self-referring women during 2000–2007 had BI-RADS D3–4 negative mammograms – all were screened with bilateral US.ResultsUS detected 37 cancers – incremental cancer detection rate (ICDR) was 0.40% (95% CI: 0.39–0.41%); ICDR was 0.33% in women <50 and 0.51% in those 50 years and older. US detected a larger proportion of cancers below age 50 compared to older women. US-only detected cancers had a more favourable stage (pTis–pT1a–pT1b: 64.8% versus 35.5%, p = 0.001; pN1: 13.5% versus 31.3%, p = 0.047) than cancers detected on mammography. US caused additional investigations in 4.9% of women and benign surgical biopsies in 0.9%. Cost per US-screened woman, and per US-detected cancer ranged between €59–62 and €14,618–15,234, respectively.ConclusionUS detects early-stage cancers in women with mammography-negative dense breasts, with higher contribution in women younger than 50 years.  相似文献

PURPOSE: To evaluate prevalence screening in the first prospective trial of a new ovarian cancer screening (OCS) strategy (risk of ovarian cancer or ROC algorithm) on the basis of age and CA125 profile. PATIENTS AND METHODS: Postmenopausal women, > or = 50 years were randomly assigned to a control group or screen group. Screening involved serum CA125, interpreted using the ROC algorithm. Participants with normal results returned to annual screening; those with intermediate results had repeat CA125 testing; and those with elevated values underwent transvaginal ultrasound (TVS). Women with abnormal or persistently equivocal TVS were referred for a gynecologic opinion. RESULTS: Thirteen thousand five hundred eighty-two women were recruited. Of 6,682 women randomly assigned to screening, 6,532 women underwent the first screen. After the initial CA125, 5,213 women were classified as normal risk, 91 women elevated, and 1,228 women intermediate. On repeat CA125 testing of the latter, a further 53 women were classified as elevated risk. All 144 women with elevated risk had TVS. Sixteen women underwent surgery. Eleven women had benign pathology; one woman had ovarian recurrence of breast cancer; one woman had borderline; and three women had primary invasive epithelial ovarian cancer (EOC). The specificity and positive predictive value (PPV) for primary invasive EOC were 99.8% (95% CI, 99.7 to 99.9) and 19% (95% CI, 4.1 to 45.6), respectively. CONCLUSION: An OCS strategy using the ROC algorithm is feasible and can achieve high specificity and PPV in postmenopausal women. It is being used in the United Kingdom Collaborative Trial of Ovarian Cancer Screening and in the United States in both the Cancer Genetics Network and the Gynecology Oncology Group trials of high-risk women.  相似文献

Between 1956 and 1990, 775 women were treated for Hodgkin's disease at The University of Texas M.D. Anderson Cancer Center. Of these, 25 (3.2%) were pregnant at diagnosis. Seven of these women were in the first trimester, 10 in the second, and eight in the third. Prior to treatment, three women in the third trimester had normal deliveries, and six patients in the first trimester had abortions. Sixteen patients received radiotherapy for supradiaphragmatic presentations during their pregnancies. All these patients had nodular sclerosing Hodgkin's disease: Two had clinical stage IA presentations and 14 had clinical stage IIA. In two patients radiotherapy (35 Gy) was limited to the neck, three patients were treated definitively to the neck and mediastinum (40 Gy), and 11 patients received mantle irradiation (40 Gy). Four to five half-value layers of lead were used to shield the uterus during radiotherapy. The dose to the fetus was estimated individually in nine patients, using a combination of an Alderson-Rando and a water phantom. The estimated total dose to the mid-fetus ranged from 1.4 to 5.5 cGy for treatment with 6 MV photons, and from 10 to 13.6 cGy for Cobalt 60. All 16 patients subsequently delivered full-term, normal infants. Following delivery, all of the patients had further staging procedures; eight received additional treatment. Subsequently, the disease relapsed in four patients; two eventually died of Hodgkin's disease. The 10-year determinant and overall survival rates were 83% and 71%, respectively. Currently, all offspring are physically and mentally normal, and none has developed a malignancy. Radiotherapy is an appropriate initial treatment for supradiaphragmatic presentations of Hodgkin's disease during the second and third trimesters of pregnancy, provided special attention is paid to treatment and shielding techniques. The outcome for women treated with irradiation for clinical stage I and II Hodgkin's disease during pregnancy has not been shown to be adversely affected by pregnancy, and after the first 8 weeks of gestation, the risk to the fetus appears to be minimal.  相似文献

We have carried out an audit of breast screening by mammography under 50 years of age in a cohort of 192 women attending family cancer clinics run by the South Thames genetic services. Of these women, six came from families in which a BRCA mutation had been identified, 61 had > 50%, 35 a 20–50% and 90 had < 20% chance of carrying a high risk mutation. In the 192 women in the screened cohort, 9 breast cancers were diagnosed (4.7%), all in high-risk women. Three were diagnosed at the prevalence screen. Three were detected mammographically at subsequent screening rounds; three were detected by breast self-examination (BSE) between screening episodes. One interval cancer was visible on mammogram at presentation but not at screening five months previously. A second cancer was also visible on mammogram at presentation but the normal screening mammogram had been 17 months earlier, outside the recommended interval. The remaining interval cancer was not visible on the mammogram. A total of 363 two-view screening mammograms were performed in the 280 person-years of follow-up; 109 additional investigations were generated: 23 recall mammograms, 18 symptomatic mammograms, 45 ultrasounds, 12 aspiration cytologies and 11 biopsies. Cytology diagnosed malignancy in 1 of 12 cases; breast biopsy in 9 of 11 cases. Twenty-three additional women had ultrasound screening only. This audit suggests that screening below the age 50 years may be unnecessary in families with a low chance of having a BRCA1 or -2 mutation, but it is important to screen high-risk women at least annually and possibly under 35 years. This revised version was published online in July 2006 with corrections to the Cover Date.  相似文献

The prevalence of clinically relevant HPV types and their specific risk for progression and regression in women with atypical squamous cells of uncertain significance (ASCUS) and low‐grade squamous intraepithelial lesions (LSIL) were studied in a routine screening population. A 4‐year cohort of women (n = 820) with ASCUS/LSIL and a positive HPV test in triage were followed for 6–9 years. The progression risks for CIN2+/CIN3+ were determined for single (71.2%) and multiple HPV infections (28.8%). The CIN2+ progression risk for all HPV 16, all HPV 35, single HPV 16 and single HPV 35 infections were 65.3% (95% CI: 59.6–71.0), 64.4% (95% CI: 50.4–78.4), 63.8% (95% CI: 56.2–71.4) and 73.7% (95% CI: 53.9–93.5), respectively. Based on CIN2+ progression risks four main groups were defined; the HPV 16 group, the HPV 31/33/35 group, the HPV 18/45/51/52 group and the HPV 39/56/58/59/66/68 group with progression risks of 65.3% (95% CI: 59.6–71.0), 62.1% (95% CI: 54.8–69.4), 52.6 (95% CI: 45.9–59.3) and 39.5 (95% CI: 33.0–46.0), respectively. In multivariate analyses, women in the age group 40–49 years had an increased risk of CIN2+ progression. As for CIN3+, HPV 16 had a higher progression risk than other HPV risk groups (p < 0.05). In multiple infections only HPV 16 had a significant additive CIN3+ progression risk (p < 0.05) as compared to other HPV risk groups. In summary, HPV types 16 and 35, including the HPV risk group 31/33/35, had a similar CIN2+ progression risk, but only HPV 16 had a higher risk for CIN3+ progression.  相似文献
