Evidence suggests that compared to younger women, older women are less likely to receive standard management for breast cancer. Whether this disparity persists once differences in tumour characteristics have been adjusted for has not been investigated in the UK. A retrospective cohort study involving case note review was undertaken, based on the North Western Cancer Registry database of women aged > or =65 years, resident in Greater Manchester with invasive breast cancer registered over a 1-year period (n=480). Adjusting for tumour characteristics associated with age by logistic regression analyses, older women were less likely to receive standard management than younger women for all indicators investigated. Compared to women aged 65-69 years, women aged > or =80 years with operable (stage 1-3a) breast cancer have increased odds of not receiving triple assessment (OR=5.5, 95% confidence interval (CI): 2.1-14.5), not receiving primary surgery (OR=43.0, 95% CI: 9.7-191.3), not undergoing axillary node surgery (OR=27.6, 95% CI: 5.6-135.9) and not undergoing tests for steroid receptors (OR=3.0, 95% CI: 1.7-5.5). Women aged 75-79 years have increased odds of not receiving radiotherapy following breast-conserving surgery compared to women aged 65-69 years (OR=11.0, 95% CI: 2.0-61.6). These results demonstrate that older women in the UK are less likely to receive standard management for breast cancer, compared to younger women and this disparity cannot be explained by differences in tumour characteristics. 相似文献

BACKGROUND: It is unknown whether differences in the quality of breast cancer care among women from racial and ethnic minority groups, the elderly, and rural areas have changed over time across the continuum of care. METHODS: The linked Surveillance, Epidemiology, and End Results-Medicare database identified 22,701 women ages 66-79 years diagnosed with early stage breast cancer from 1992-1999. Multiple breast cancer processes of care were measured, including breast-conserving surgery, radiation therapy, documentation of estrogen receptor status, surveillance mammography, and a combined measure of "adequate care". RESULTS: African-American and Hispanic women were significantly less likely to receive adequate care than White women in unadjusted comparisons (54.7% and 58.0% vs. 68.4% for African-American and Hispanic vs. White women) and adjusted comparisons (adjusted odds ratio [AOR] 0.67; 95% confidence interval [95% CI] 0.59-0.76, and AOR 0.77; 95% CI 0.66-0.90 for African-American and Hispanic women, respectively). The proportion of Asian/Pacific Islander women receiving adequate care was similar to White women. When considering only women diagnosed with breast cancer from 1997-1999, African-American women remained less likely than White women to receive adequate care (AOR 0.63; 95% CI 0.50-0.79). Women ages 75-79 years were less likely to receive adequate care compared with women ages 66-69 years (AOR 0.74; 95% CI 0.69-0.80), and women from rural (vs. metropolitan) areas were less likely to receive adequate care (AOR 0.81; 95% CI 0.73-0.89). CONCLUSIONS: The quality of breast cancer care is lower among vulnerable populations across the continuum of care, and many of these differences have not improved in more recent years. 相似文献

BACKGROUND: The authors hypothesized that insurance payer and race would influence the care and outcomes for patients with breast carcinoma. METHODS: The authors examined treatments and adjusted risk of death (through 1997) for all incident cases of breast carcinoma occurring in Florida in 1994 (n = 11,113) by using state tumor registry data. RESULTS: Patients lacking health insurance were less likely to receive breast-conserving surgery (BCS) compared with patients who had private health insurance. Among patients insured by Medicare, those belonging to a health maintenance organization (HMO) were more likely to receive BCS but less likely to receive radiation therapy after BCS. Non-Hispanic African Americans had higher mortality rates even when stage at diagnosis, insurance payer, and treatment modalities used were adjusted in multivariate models (adjusted risk ratio [RR], 1.35; 95% confidence interval [CI], 1.12-1.61; P = 0.001). Patients who had HMO insurance had similar survival rates compared with those with fee-for-service (FFS) insurance. Among non-Medicare patients, mortality rates were higher for patients who had Medicaid insurance (RR, 1.58, 95% CI, 1.18-2.11; P = 0.002) and those who lacked health insurance (RR, 1.31; 95% CI, 1.03-1.68; P = 0.03) compared with patients who had commercial FFS insurance. There were no insurance-related differences in survival rates, however, once stage at diagnosis was controlled. CONCLUSIONS: As a result of later stage at diagnosis, patients with breast carcinoma who were uninsured, or insured by Medicaid, had higher mortality rates. Mortality rates were also higher among non-Hispanic African Americans, a finding that was not fully explained by differences in stage at diagnosis, treatment modalities used, or insurance payer. 相似文献

BackgroundBreast reconstruction is an option for women undergoing mastectomy for breast cancer. Previous studies have reported underutilization of reconstructive surgery. This study aims to examine the role demographic, clinical and socio-economic factors may have on patients’ decisions to undergo breast reconstruction.MethodsWe analyzed data from our institutional database. Using multivariable and multinomial logistic regression, we compared breast cancer patients who had undergone mastectomy-only to those who had immediate breast reconstruction (overall and by type of reconstruction).ResultsWe analyzed data on 1459 women who underwent mastectomy during the period 2003–2015. Of these, 475 (32.6%) underwent mastectomy-only and 984 (67.4%) also underwent immediate breast reconstruction. After adjusting for potential confounders, older age (OR = 0.18, 95%CI:0.08–0.40), Asian race (OR = 0.29, 95%CI:0.19–0.45), bilateral mastectomy (OR = 0.71, 95%CI:0.56–0.90), and higher stage of disease (OR = 0.44, 95%CI:0.26–0.74) were independent risk factors for not receiving immediate breast reconstruction. Furthermore, patients with Medicare or Medicaid insurance were less likely than patients with private insurance to receive an autologous reconstruction. There was no evidence for changes over time in the way socio-demographic and clinical factors were related to receiving immediate breast reconstruction after mastectomy.ConclusionsClinical characteristics, sociodemographic factors like age, race and insurance coverage affect the decision for reconstructive surgery following mastectomy. 相似文献

Cancer occurrence after cosmetic breast implantation in Denmark 总被引:2,自引:0,他引:2
Mellemkjaer L Kjøller K Friis S McLaughlin JK Høgsted C Winther JF Breiting V Krag C Krüger Kjaer S Blot WJ Olsen JH 《International journal of cancer. Journal international du cancer》2000,88(2):301-306
Most studies on cancer incidence after breast implantation have focused on breast cancer, while the risk of cancers at other sites has been less well investigated. We examined cancer incidence among 1,653 women who underwent cosmetic breast implant surgery at private clinics of plastic surgery in Denmark and 1,736 women attending the same clinics for other reasons during the period 1973-1995. Furthermore, we updated previously reported results among 1,114 women who received implants for cosmetic indications at public hospitals. All women were followed for cancer through the Danish Cancer Registry. In comparison with the general female population, the overall standardized incidence ratio (SIR) for cancer among women who received implants in private clinics was 1.65 [95% confidence interval (CI) = 1.17-2.27]. This elevated SIR reflected increased incidence ratios for almost all major cancer sites; however, only for non-melanoma skin cancer was there an excess of more than 2 cases. No significant excess of cancer was observed among women who received implants in public hospitals (SIR = 1.10, 95% CI = 0.76-1.52) or among women attending the private clinics for other problems (SIR = 1.10, 95% CI = 0.78-1.52). The SIRs for breast cancer after breast implantation were 1.1 (95% CI = 0.5-2.2) among private clinic patients and 0.9 (95% CI = 0.4-1.7) among public hospital patients. The overall findings of these 2 implant cohorts and results from other investigations suggest that cancer risk is probably not increased among women receiving cosmetic breast implants. The inconsistent results for private clinics and public hospitals are likely related to selection bias and confounding among the private clinic patients, but our data did not permit exploration of these possibilities. Further research into the determinants of these inconsistencies is warranted. 相似文献

BACKGROUND: Older women have high rates of breast carcinoma, and there are substantial variations in the patterns of care for this population group. METHODS: The authors studied 718 breast carcinoma patients age 67 years and older who were diagnosed with localized disease between 1995 and 1997 from 29 hospitals in 5 regions. Data were collected from patients, charts, and surgeons. Logistic regression analysis was used to evaluate determinants of treatment. RESULTS: Women who were concerned about body image were 1.8 times more likely (95% confidence interval [95% CI], 1.1-2.8) to receive breast conservation surgery and radiotherapy than women without this preference, controlling for other factors. In contrast, women who preferred receiving no therapy beyond surgery were 3.9 times more likely (95% CI, 2.9-6.1) to undergo mastectomy than other women, after considering other factors. Radiotherapy was omitted after breast conservation 3.4 times more often (95% CI, 2.0-5.6) among women age 80 years and older than among women ages 67-79 years, controlling for covariates. Black women tended to have radiotherapy omitted after breast conservation surgery 2.0 times more often (95% CI, 0.9-4.4) than white women (P = 0.09). Women age 80 years and older also were 70% less likely (odds ratio = 0.3; 95% CI, 0.1-0.8) to receive chemotherapy than women ages 67-79 years, controlling for health, functional status, and other covariates. CONCLUSIONS: After considering other factors, patient preferences and age were found to be associated with breast carcinoma treatment patterns in older women. Further research and training are needed to provide care for the growing population of older women that is both clinically appropriate and consonant with a woman's preferences. 相似文献

Women with a BRCA1 or BRCA2 mutation have an elevated risk of breast cancer and of contralateral breast cancer. In this study, we estimate the risk of non-synchronous ipsilateral breast cancer after a diagnosis of breast cancer in BRCA carriers and evaluate the effects of various treatments on this risk. Patients were 396 women with stage I or stage II breast cancer with an intact ipsilateral breast and for whom a BRCA1 or BRCA2 mutation had been identified in the family. Patients were followed from the initial diagnosis of cancer until the first of ipsilateral mastectomy, ipsilateral breast cancer, death or last follow-up. The 5-year actuarial risk of ipsilateral breast cancer was 5.8% (95% CI 3.2-8.4%) and the 10-year risk was 12.9% (95% CI 8.7-17.1%). Subjects who received chemotherapy had a significantly lower risk of ipsilateral breast cancer compared to those who did not receive chemotherapy (RR 0.45; 95% CI 0.24-0.84; P = 0.01). Radiotherapy was associated with a reduced risk of ipsilateral breast cancer (RR 0.28; 95% CI 0.12-0.63; P = 0.002). Oophorectomy was associated with a significant reduction in the risk of ipsilateral breast cancer (RR 0.33; 95% CI; 0.13-0.81; P = 0.02). On average, following a diagnosis of breast cancer, the annual risk of ipsilateral breast cancer risk in BRCA mutation carriers is 1.2% per year. For women treated with chemotherapy, radiation therapy or oophorectomy the risk is low, compared to women who did not receive any of these treatments. 相似文献

Although younger women with breast cancer have the most to gain from receipt of optimal care, few data are available regarding their receipt of locoregional breast cancer treatments. We identified 317,596 women aged 18-64 who were diagnosed with invasive breast cancer at hospitals reporting to the National Cancer Database, a large national cancer registry, during 2004-2008. We used multivariable logistic regression to assess the association of patient age with mastectomy versus breast-conserving surgery (BCS), radiation with BCS, and postmastectomy radiation therapy (PMRT) with varying indications, adjusting for patient, clinical, and facility characteristics. Overall, 4?% of women were 35?years old or younger and 7?% were 36-40?years old. Women ≤age 40 were significantly more likely to have mastectomy than BCS compared with older women (57?% for age ≤35 and 52?% for ages 36-40 vs. 35?% for ages 61-64, adjusted odds ratio [OR] for age ≤35?=?2.03; 95?% confidence interval (CI) 1.93-2.14 and OR for ages 36-40?=?1.76; 95?% CI 1.69-1.84). Younger women were less likely to receive radiation if BCS was performed (69 and 73 vs. 80?%, OR for age ≤35?=?0.69; 95?% CI 0.65-0.74 and OR for ages 36-40?=?0.74; 95?% CI 0.70-0.78). For those who underwent mastectomy, overall rates of PMRT were low, although women ≤age 35 and ages 36-40 (vs. ages 61-64) were more likely to receive PMRT regardless of clinical indications. Our study suggests that young women with breast cancer may not be receiving optimal locoregional therapy. Efforts are needed to confirm these findings, further understand barriers to care, and increase the receipt of appropriate adjuvant radiation therapy among young women to improve their disease-free and overall survival. 相似文献

Results from recent studies indicate that many women in the US undergo routine screening for breast cancer, but some groups of women are under-screened. In this study, we examined the breast cancer screening practices of white and black women in the United States, according to Hispanic ethnicity and other factors, using data from the 2000 National Health Interview Survey. Among women aged > or =40 years, 71.2% (95% confidence interval, CI: 70.0-72.4%) of the 8201 white women and 67.6% (95% CI: 64.5-70.6%) of the 1474 black women in this sample reported having a mammogram in the past two years. About 60.3% (95% CI: 56.7-70.3%) of 970 Hispanic women (including those who reported they were white or black) and 71.5% (95% CI: 70.3-72.7%) of 8705 non-Hispanic women reported having a mammogram in the past two years. About 74.8% (95% CI: 73.8-76.8%) of 8176 white women and 73.8% (95% CI: 71.1-76.6%) of 1471 black women aged > or =40 years had received a clinical breast examination in the past two years. About 60.1% (95% CI: 56.1-64.0%) of 969 Hispanic women (including those who reported they were white or black) and 75.6% (95% CI: 74.6-76.6%) of 8678 non-Hispanic women had received a clinical breast examination in the past two years. Women with lower incomes, those with less education, and recent immigrants were less likely to be screened. Women who had a usual source of health care and those with health insurance coverage were more likely to have been screened. These results underscore the need for continued efforts to ensure that uninsured women and those who are medically underserved have access to cancer screening services. 相似文献

Active smoking has little or no effect on breast cancer risk but some investigators have suggested that passive smoking and its interaction with active smoking may be associated with an increased risk. In a population based case-control study of breast cancer in women aged 36-45 years at diagnosis, information on active smoking, passive smoking in the home, and other factors, was collected at interview from 639 cases and 640 controls. Women were categorised jointly by their active and passive smoking exposure. Among never smoking controls, women who also reported no passive smoking exposure were significantly more likely to be nulliparous and to be recent users of oral contraceptives. Among those never exposed to passive smoking, there was no significant association between active smoking and breast cancer, relative risk (RR) of 1.12 (95% confidence interval (CI) 0.72-1.73) for past smokers and RR of 1.19 (95% CI 0.72-1.95) for current smokers, nor was there an association with age started, duration or intensity of active smoking. Compared with women who were never active nor passive smokers, there was no significant association between passive smoking in the home and breast cancer risk in never smokers, RR of 0.89 (95% CI 0.64-1.25), in past smokers, RR of 1.09 (95% CI 0.75-1.56), or in current smokers, RR of 0.93 (95% CI 0.67-1.30). There was no trend with increasing duration of passive smoking and there was no heterogeneity among any of the subgroups examined. In this study, there was no evidence of an association between either active smoking or passive smoking in the home and risk of breast cancer. 相似文献

Summary Guidelines for the optimal treatment of breast cancer have been publicized over the past 15 years, yet clinical practices continue to vary substantially in the United States. This article reviews the literature on variations in local and systemic treatment of breast cancer by patient and provider characteristics.Studies of local therapy have consistently demonstrated that older women are less likely than younger women to receive radiation therapy after breast-conserving surgery. Some studies have noted that black women are less likely than white women to receive breast-conserving surgery and less likely to receive radiation therapy after breast-conserving surgery. Rates of breast-conserving surgery vary three-fold among geographic regions and between teaching and non-teaching hospitals. Patients at smaller hospitals appear less likely to receive indicated radiation therapy.Patterns of systemic therapy have not been well described. Women over age 75 may not be receiving adequate hormonal therapy, but recent data are not available. Limited data suggest that rates of systemic therapy do not vary substantially by race or Hispanic ethnicity, but women without health insurance may not be receiving appropriate chemotherapy. Studies relating hospital and physician characteristics to the use of systemic therapy are sparse and inconclusive.In order to increase the proportion of women who receive optimal treatment for breast cancer and ensure greater equity, a more sophisticated understanding of variations in clinical practice will be required. These variations may arise from insufficient knowledge of or disagreement with guidelines among physicians, inadequate communication between physicians and patients, and individual preferences or clinical attributes of patients. Future studies will need to explore the dialogue between women and their physicians that leads to decisions about treatment of breast cancer. 相似文献

BACKGROUND: Breast-conserving surgery combined with radiation (BCSR) is the recommended alternative treatment to mastectomy for local breast carcinoma. However, limited access to healthcare may result in more extensive surgical treatment. The effect of distance to radiation therapy facilities on the likelihood of receiving BCSR was examined in Florida. METHODS: Local breast carcinomas reported to Florida's statewide registry between July, 1997, and December, 2000 were linked to the Agency of Healthcare Administration inpatient and outpatient databases to supplement the registry's treatment data, resulting in 18,903 local breast carcinoma cases treated with BCSR or mastectomy. The odds of receiving BCSR were modeled as a function of distance to the closest radiation therapy facility, adjusting for health insurance, age, race/ethnicity, and marital status. RESULTS: Distance to the closest radiation therapy facility was negatively associated with BCSR, with the odds ratio (OR) decreasing by 3% per 5-mile increase in distance. Compared with the uninsured, privately insured women were 49% more likely to receive BCSR (OR of 1.49; 95% confidence interval [95% CI], 1.20-1.86) and Medicare patients were 37% more likely (OR of 1.37; 95% CI, 1.09-1.72). Age at diagnosis was negatively associated, reducing the odds of BCSR by 1% per year increase in age. Compared with white non-Hispanic, Hispanic women were 38% less likely to receive BCSR (OR of 0.62; 95% CI, 0.55-0.71). Married women were 23% more likely to receive BCSR compared with singles (OR of 1.23; 95% CI, 1.09-1.40); women who were separated, divorced, or widowed did not differ significantly from single women. CONCLUSIONS: Distance to radiation therapy facilities may negatively impact the likelihood of BCSR in Florida. Age at diagnosis, insurance type, race/ethnicity, and marital status were associated with BCSR. Future efforts should target the uninsured, Hispanics, the elderly, and the unmarried women to reduce disparities in the administration of BCSR for local breast carcinoma. 相似文献

A major risk factor for breast cancer is having a first-degree family history of the disease. Benign breast disease (BBD), particularly atypical hyperplasia, is also associated with an increased risk of breast cancer. However, the relationship between family history of breast cancer and BBD is unclear. From 1989 through 1997, 80,995 participants in the Nurses' Health Study II were followed; 16,849 reported a first diagnosis of BBD. Pathology slides were reviewed for 1,465 women who reported having a tissue biopsy, and these were classified as nonproliferative BBD, proliferative BBD without atypia or atypical hyperplasia. Women with a family history of breast cancer were more likely to report a physician diagnosis of BBD [rate ratio (RR) = 1.38, 95% confidence interval (CI) 1.29-1.46]. The magnitude of this association declined with age from RR = 1.96 (95% CI 1.55-2.47) at 25-29 years to RR = 1.20 (95% CI 0.95-1.52) at age 45-50 years. Among women with proliferative disease, those with a family history of breast cancer were almost 3 times as likely to have atypia (prevalence odds ratio = 2.72, 95% CI 1.23-5.89) than those with no family history. In conclusion, women with a family history of breast cancer appear to be at increased risk of being diagnosed with BBD, in particular the high-risk types of BBD associated with a greatly increased risk of breast cancer. This link adds weight to the belief that BBD with atypia is a precursor or marker lesion for breast cancer. 相似文献

Recent studies suggest that Asian and Pacific Islander women in the United States may underuse cancer screening tests. We examined the breast and cervical cancer screening practices of 6048 Asian and Pacific Islander women in 49 states from 1994 through 1997 using data from the Behavioral Risk Factor Surveillance System. About 71.7% [95% confidence interval (CI), 66.3-77.0%] of women in this sample aged > or =50 years had a mammogram in the past 2 years, and 69.5% (95% CI, 63.9-75.1%) had a clinical breast exam in the past 2 years. About 73.7% (95% CI, 71.3-76.0%) of women aged > or =18 years who had not undergone a hysterectomy had a Papanicolaou test in the past 3 years. Women with health insurance and those who had seen a physician in the past year were more likely to have been screened. These results underscore the need for continued efforts to ensure that Asian and Pacific Islander women who are medically underserved, including those without health insurance, have access to cancer screening services. 相似文献

BACKGROUND:
Lack of health insurance is a key barrier to accessing care for chronic conditions and cancer screening. The influence of insurance type (private, public, none) on survivor‐focused and general preventive health care in adult survivors of childhood cancer was examined.METHODS:
The Childhood Cancer Survivor Study is a retrospective cohort study of childhood cancer survivors diagnosed between 1970 and 1986. Among 8425 adult survivors, the relative risk (RR) and 95% confidence interval (CI) of receiving survivor‐focused and general preventive health care were estimated for uninsured (n = 1390) and publicly insured (n = 640), compared with for the privately insured (n = 6395)RESULTS:
Uninsured survivors were less likely than those privately insured to report a cancer‐related visit (adjusted RR, 0.83; 95% CI, 0.75‐0.91) or a cancer center visit (adjusted RR, 0.83; 95% CI, 0.71‐0.98). Uninsured survivors had lower levels of utilization in all measures of care in comparison with privately insured. In contrast, publicly insured survivors were more likely to report a cancer‐related visit (adjusted RR, 1.22; 95% CI, 1.11‐1.35) or a cancer center visit (adjusted RR, 1.41; 95% CI, 1.18‐1.70) than were privately insured survivors. Although publicly insured survivors had similar utilization of general health examinations, they were less likely to report a Papanicolaou test or a dental examinationsCONCLUSIONS:
Among this large, socioeconomically diverse cohort, publicly insured survivors utilize survivor‐focused health care at rates at least as high as survivors with private insurance. Uninsured survivors have lower utilization of both survivor‐focused and general preventive health care. Cancer 2011. © 2010 American Cancer Society. 相似文献17.
Perceived medical discrimination and cancer screening behaviors of racial and ethnic minority adults
LaVera M Crawley David K Ahn Marilyn A Winkleby 《Cancer epidemiology, biomarkers & prevention》2008,17(8):1937-1944
BACKGROUND: Discrimination has been shown as a major causal factor in health disparities, yet little is known about the relationship between perceived medical discrimination (versus general discrimination outside of medical settings) and cancer screening behaviors. We examined whether perceived medical discrimination is associated with lower screening rates for colorectal and breast cancers among racial and ethnic minority adult Californians. METHODS: Pooled cross-sectional data from 2003 and 2005 California Health Interview Survey were examined for cancer screening trends among African American, American Indian/Alaskan Native, Asian, and Latino adult respondents reporting perceived medical discrimination compared with those not reporting discrimination (n = 11,245). Outcome measures were dichotomous screening variables for colorectal cancer among respondents ages 50 to 75 years and breast cancer among women ages 40 to 75 years. RESULTS: Women perceiving medical discrimination were less likely to be screened for colorectal [odds ratio (OR), 0.66; 95% confidence interval (95% CI), 0.64-0.69] or breast cancer (OR, 0.52; 95% CI, 0.51-0.54) compared with women not perceiving discrimination. Although men who perceived medical discrimination were no less likely to be screened for colorectal cancer than those who did not (OR, 1.02; 95% CI, 0.97-1.07), significantly lower screening rates were found among men who perceived discrimination and reported having a usual source of health care (OR, 0.30; 95% CI, 0.28-0.32). CONCLUSIONS: These findings of a significant association between perceived racial or ethnic-based medical discrimination and cancer screening behaviors have serious implications for cancer health disparities. Gender differences in patterns for screening and perceived medical discrimination warrant further investigation. 相似文献

To describe which providers provide breast cancer survivorship care, we conducted a longitudinal survey of nonmetastatic breast cancer patients identified by the SEER registries of Los Angeles and Detroit. Multinomial logistic regression examined the adjusted odds of surgeon compared with a medical oncologist follow-up or primary care provider compared with medical oncologist follow-up, adjusting for age, race/ethnicity, insurance, tumor stage, receipt of chemotherapy, endocrine therapy use, and visit to a medical oncologist at the time of diagnosis. Results were weighted to account for sample selection and nonresponse. 844 women had invasive disease and received chemotherapy or endocrine therapy. 65.2 % reported medical oncologists as their main care provider at 4 years, followed by PCP/other physicians (24.3 %) and surgeons (10.5 %). Black women were more likely to receive their follow-up care from surgeons (OR 2.47, 95 % CI 1.16–5.27) or PCP/other physicians (OR 2.62, 95 % CI 1.47–4.65) than medical oncologists. Latinas were more likely to report PCP/other physician follow-up than medical oncologists (OR 2.33, 95 % CI 1.15–4.73). Compared with privately insured women, Medicaid recipients were more likely to report PCP/other physician follow-up (OR 2.52, 95 % CI 1.24–5.15). Women taking endocrine therapy 4 years after diagnosis were less likely to report surgeons or PCP/other physicians as their primary provider of breast cancer follow-up care. Different survivorship care patterns emerge on race/ethnicity and insurance status. Interventions are needed to inform patients and providers on the recommended sources of breast cancer follow-up. 相似文献

To investigate the risk of breast cancer development in women with benign breast disease (BBD), 387 screen-detected BBD women and 1,489 normal women, taken from participants in the breast cancer screening program during 1978-1986, were followed through 1991. While 2,811 person-years in the BBD group and 11,018 person-years in the normal group were accumulated, 5 women in the BBD group and 6 women in the normal group developed breast cancer. Using the Mantel-Haenszel method, relative risks (RR) were estimated for all women with BBD and women in some BBD types. Significantly elevated risk of breast cancer was observed in all women with BBD (RR = 3.26, 95% confidence interval (CI) 1.08-9.83). Women with proliferative BBD were at high risk of breast cancer (RR = 8.48, 95% CI 2.99-24.10), but no increased risk was observed for women with non-proliferative BBD (RR = 0.93, 95% CI 0.11-7.66). These results are consistent with those in high-risk countries for breast cancer. In the management of women with BBD, histopathological diagnosis of the breast lesion is essential and women with proliferative BBD should be followed up carefully. 相似文献

Testing for mutations in BRCA1 and BRCA2 can provide important information about breast and ovarian cancer risk to a small but identifiable subgroup of women. Women who test positive for a BRCA1/2 mutation can pursue more aggressive cancer surveillance and prevention regimens. Among families with known mutations, women who test negative may avoid unnecessary interventions. Currently, little is known about the factors associated with the use of clinical BRCA1/2 testing. The objective of this study was to determine the factors associated with decisions about clinical BRCA1/2 testing among women undergoing clinical BRCA1/2 counseling through a retrospective cohort study of women who participated in a university-based clinic offering breast cancer risk assessment, genetic counseling, and BRCA1/2 testing between January 1996 and April 1998. From the 251 eligible women who responded to a follow-up survey, 125 (50%) had undergone or were undergoing BRCA1/2 testing, 86 (34%) had decided not to undergo testing, and 40 (16%) were undecided about testing. After multivariate adjustment, we found that women who chose to undergo BRCA1/2 testing were more likely to have a known familial mutation [odds ratio (OR), 7.46; 95% confidence interval (CI), 0.97-62.16], more likely to be Ashkenazi Jewish (OR, 6.37; 95% CI, 2.68-15.12), more likely to want cancer risk information for family members (OR, 1.93; 95% CI, 0.99-4.14), more likely to want information about ovarian cancer risk (OR, 1.69; 95% CI, 1.18-3.69), and less likely to be concerned about insurance or job discrimination (OR, 0.45; 95% CI, 0.21-0.94). These associations were also found in the subgroup of women with a predicted probability of a BRCA1 mutation of 25%. Our study suggests that approximately half of eligible women choose to undergo clinical BRCA1/2 testing after participating in counseling. Women who have the highest risk of carrying a mutation, and thus the greatest probability of gaining some useful information from the test results, are most likely to undergo testing. Women who undergo testing are also more interested in ovarian cancer risk information and less concerned about job and insurance discrimination. 相似文献
