Dissecting the journey to breast cancer diagnosis in sub-Saharan Africa: Findings from the multicountry ABC-DO cohort study. Int J Cancer 2021; 148:340-351. [PMID: 32663320 PMCID: PMC7754476 DOI: 10.1002/ijc.33209] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2020] [Revised: 05/29/2020] [Accepted: 06/23/2020] [Indexed: 12/11/2022]
Abstract
Most breast cancer patients in sub-Saharan Africa are diagnosed at advanced stages after prolonged symptomatic periods. In the multicountry African Breast Cancer-Disparities in Outcomes cohort, we dissected the diagnostic journey to inform downstaging interventions. At hospital presentation for breast cancer, women recalled their diagnostic journey, including dates of first noticing symptoms and health-care provider (HCP) visits. Negative binomial regression models were used to identify correlates of the length of the diagnostic journey. Among 1429 women, the median (inter-quartile range) length (months) of the diagnostic journey ranged from 11.3 (5.7-21.2) in Ugandan, 8.2 (3.4-16.4) in Zambian, 6.5 (2.4-15.7) in Namibian-black to 5.6 (2.3-13.1) in Nigerian and 2.4 (0.6-5.5) in Namibian-non-black women. Time from first HCP contact to diagnosis represented, on average, 58% to 79% of the diagnostic journey in each setting except Nigeria where most women presented directly to the diagnostic hospital with advanced disease. The median number of HCPs visited was 1 to 4 per woman, but time intervals between visits were long. Women who attributed their initial symptoms to cancer had a 4.1 months (absolute) reduced diagnostic journey than those who did not, while less-educated (none/primary) women had a 3.6 months longer journey than more educated women. In most settings the long journey to breast cancer diagnosis was not primarily due to late first presentation but to prolonged delays after first presentation to diagnosis. Promotion of breast cancer awareness and implementation of accelerated referral pathways for women with suspicious symptoms are vital to downstaging the disease in the region.

Abstract
Multiple social and financial barriers exist to breast cancer detection in Pakistan, which may cause a delay in seeking care and the final diagnosis. This analytical study documents the pathways and time courses associated with referral to diagnostic centres to evaluate the clinical signs and symptoms of breast cancer. This report also verifies the association between socio-demographic and clinical indicators concerning the length of time spent before reaching diagnostic facilities. A purposive sample of 200 patients was selected from two tertiary care hospitals in Lahore, Pakistan, for the interviews. Descriptive statistics (that is, percentages, frequencies, and measures of central tendencies) and a multiple linear regression model were used to achieve the study objectives. The descriptive model showed 31-128 days interval between a patient's awareness of a clinical sign or symptom and receiving care. The healthcare system, including traditional healers, took from 7 to 194 days, and the time to diagnosis ranged from 15 to 30 days. Pain severity, larger tumour size, lack of clinical improvement, and the desire to obtain better treatment were reasons given for seeking care, but lack of awareness and fear of financial burden related to accessing healthcare facilities were identified as barriers. Moreover, socio-demographic and other predictive clinical factors were potentially associated with and substantially influenced the likelihood of the increased length of breast cancer patients' time to reach diagnostic centres. In conclusion, referrals by multiple healthcare providers, especially traditional healers and general practitioners, was a significant predictor for delay in diagnosis. Therefore, increased awareness and a responsive healthcare system may reduce the time from the recognition of symptoms to the early detection of breast cancer among women, thus improving outcomes in a developing country.

Abstract
BACKGROUND Insurance may lengthen or inhibit time to follow-up after positive screening mammography. We assessed the association between insurance status and time to initial diagnostic follow-up after a positive screening mammogram. METHODS Using 1995-2010 data from a North Carolina population-based registry of breast imaging and cancer outcomes, we identified women with a positive screening mammogram. We compared receipt of follow-up within 60 days of screening using logistic regression and evaluated time to follow-up initiation using Cox proportional hazards regression. RESULTS Among 43,026 women included in the study, 73% were <65 years and 27% were 65+ years. Median time until initial diagnostic follow-up was similar by age group and insurance status. In the adjusted model for women <65, uninsured women experienced a longer time to initiation of diagnostic follow-up [HR, 0.47; 95% confidence interval (CI), 0.25-0.89] versus women with private insurance. There were increased odds of these uninsured women not meeting the Centers for Disease Control and Prevention guideline for follow-up within 60 days (OR, 1.59; 95% CI, 1.31-1.94). Among women ages 65+, women with private insurance experienced a faster time to follow-up (adjusted HR, 2.09; 95% CI, 1.27-3.44) than women with Medicare and private insurance. Approximately 10% of women had no follow-up by 365 days. CONCLUSIONS We found differences in time to initial diagnostic follow-up after a positive screening mammogram by insurance status and age group. Uninsured women younger than 65 years at a positive screening event had delayed follow-up.

J Rural Health 2017; 34 Suppl 1:s91-s103. [PMID: 28102909 DOI: 10.1111/jrh.12226] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2016] [Revised: 08/26/2016] [Accepted: 10/27/2016] [Indexed: 12/17/2022]
Abstract
PURPOSE Despite being generally accepted that delays in diagnosing breast cancer are of prognostic and psychological concern, the influence of hospital characteristics on such delays remains poorly understood, especially in rural and underserved areas. However, hospital characteristics have been tied to greater efficiency and warrant further investigation as they may have implications for breast cancer care in these areas. METHODS Study data were derived from the Kentucky, North Carolina, Ohio, and Pennsylvania state central cancer registries (2006-2008). We then linked Medicare enrollment files and claims data (2005-2009), the Area Resource File (2006-2008), and the American Hospital Association Annual Survey of Hospitals (2007) to create an integrated data set. Hierarchical linear modeling was used to regress the natural log of breast cancer diagnosis delay on a number of hospital-level, demographic, and clinical characteristics. FINDINGS The baseline study sample consisted of 4,547 breast cancer patients enrolled in Medicare that lived in Appalachian counties at the time of diagnosis. We found that hospitals with for-profit ownership (P < .01) had shorter diagnosis delays than their counterparts. Estimates for comprehensive oncology services, system membership and size were not statistically significant at conventional levels. CONCLUSIONS Some structural characteristics of hospitals (eg, for-profit ownership) in the Appalachian region are associated with having shorter delays in diagnosing breast cancer. Researchers and practitioners must go beyond examining patient-level demographic and tumor characteristics to better understand the drivers of timely cancer diagnosis, especially in rural and underserved areas.

Abstract
BACKGROUND Women with breast or cervical cancer abnormalities can experience barriers to timely follow-up care, resulting in delays in cancer diagnosis. Patient navigation programs that identify and remove barriers to ensure timely receipt of care are proliferating nationally. The study used a systematic framework to describe barriers, including differences between African American and Latina women; to determine recurrence of barriers; and to examine factors associated with barriers to follow-up care. METHODS Data originated from 250 women in the intervention arm of the Chicago Patient Navigation Research Program (PNRP). The women had abnormal cancer screening findings and navigator encounters. Women were recruited from a community health center and a publicly owned medical center. After describing proportions of African American and Latina women experiencing particular barriers, logistic regression was used to explore associations between patient characteristics, such as race/ethnicity, and type of barriers. RESULTS The most frequent barriers occurred at the intrapersonal level (e.g., insurance issues and fear), while institutional-level barriers such as system problems with scheduling care were the most commonly recurring over time (29%). The majority of barriers (58%) were reported in the first navigator encounter. Latinas (81%) reported barriers more often than African American women (19%). Differences in race/ethnicity and employment status were associated with types of barriers. Compared to African American women, Latinas were more likely to report an intrapersonal level barrier. Unemployed women were more likely to report an institutional level barrier. CONCLUSION In a sample of highly vulnerable women, there is no single characteristic (e.g., uninsured) that predicts what kinds of barriers a woman is likely to have. Nevertheless, navigators appear able to easily resolve intrapersonal-level barriers, but ongoing navigation is needed to address system-level barriers. Patient navigation programs can adopt the PNRP barriers framework to assist their efforts in assuring timely follow-up care.

Abstract
We examined differences in time to diagnosis by race/ethnicity, the relationship between time to diagnosis and stage, and the extent to which it explains differences in stage at diagnosis across racial/ethnic groups. Our analytic sample includes 21,427 non-Hispanic White (White), Hispanic, non-Hispanic Black (Black) and non-Hispanic Asian/Pacific Islander (Asian) women diagnosed with stage I to IV breast cancer between January 1, 2000 and December 31, 2007 at one of eight National Comprehensive Cancer Network centers. We measured time from initial abnormal mammogram or symptom to breast cancer diagnosis. Stage was classified using AJCC criteria. Initial sign of breast cancer modified the association between race/ethnicity and time to diagnosis. Among symptomatic women, median time to diagnosis ranged from 36 days among Whites to 53.6 for Blacks. Among women with abnormal mammograms, median time to diagnosis ranged from 21 days among Whites to 29 for Blacks. Blacks had the highest proportion (26 %) of Stage III or IV tumors. After accounting for time to diagnosis, the observed increased risk of stage III/IV breast cancer was reduced from 40 to 28 % among Hispanics and from 113 to 100 % among Blacks, but estimates remained statistically significant. We were unable to fully account for the higher proportion of late-stage tumors among Blacks. Blacks and Hispanics experienced longer time to diagnosis than Whites, and Blacks were more likely to be diagnosed with late-stage tumors. Longer time to diagnosis did not fully explain differences in stage between racial/ethnicity groups.

Abstract
BACKGROUND Comorbid conditions influence the survival of cancer patients. This study evaluated the influence of comorbidity on survival among lung cancer patients. METHODS The authors evaluated the medical records of 1111 lung cancer patients of a medical center in Taiwan. Days of survival were calculated for each patient and mortality hazard ratios were estimated for associations with demographic status, comorbidity and cancer stage at diagnosis. RESULTS On average, the survival time was slightly longer among women than among men (838±689 vs. 749±654 days, p = 0.050). Survival days increased with age (from 580±526 [≤ 50 years] to 803±693 [≥ 71 years] days, p = 0.020) and decreased with stage (from 1224±656 [stage I] to 489±536 [stage IV] days, p < 0.001). Younger patients were more likely to be diagnosed with lung cancer at a late stage. Compared with lung cancer patients without tuberculosis, those with tuberculosis had a significantly shorter average survival duration (584 vs. 791 days, p = 0.002) and a higher mortality hazard ratio (1.30, 95% CI: 1.03 - 1.65). A similar trend was observed in lung cancer patients with diabetes. CONCLUSIONS Lung cancer patients with comorbid tuberculosis or diabetes are at an elevated risk of mortality. These patients deserve greater attention while undergoing cancer treatment.

Abstract
BACKGROUND Health systems in Sub-Saharan Africa are not prepared for the rapid rise in cancer rates projected in the region over the next decades. More must be understood about the current state of cancer care in this region to target improvement efforts. Yaounde General Hospital (YGH) currently is the only site in Cameroon (population: 18.8 million) where adults can receive chemotherapy from trained medical oncologists. The experiences of patients at this facility represent a useful paradigm for describing cancer care in this region. METHODS In July and August 2010, our multidisciplinary team conducted closed-end interviews with 79 consecutive patients who had confirmed breast cancer, Kaposi sarcoma, or lymphoma. RESULTS Thirty-five percent of patients waited >6 months to speak to a health care provider after the first sign of their cancer. The delay between first consultation with a health care provider and receipt of a cancer diagnosis was >3 months for 47% of patients. The total delay from the first sign of cancer to receipt of the correct diagnosis was >6 months for 63% of patients. Twenty-three percent of patients traveled for >7 hours to reach YGH, and 40% of patients interviewed spent >$200 on a single round of chemotherapy. CONCLUSIONS Cancer patients experienced numerous geographic and health care system challenges, resulting in significant delays in receiving diagnosis and treatment, even for cancers highly amenable to early intervention. This unacceptable and unethical situation is likely explained by limited knowledge about cancer among patients and health care professionals, government neglect, poverty, and reliance on traditional healers.

Abstract
Breast cancer is the most common cancer among Egyptian women, accounting for 37.6% of female tumors, and is often diagnosed at later stages. The objective of this study was to investigate breast cancer patient navigation through the health care system in the Nile Delta. Interviews were conducted with 163 newly diagnosed breast cancer patients at the Tanta Cancer Center (TCC), the major cancer center of the region. Patients described their medical care pathway from the initial symptom experienced until their arrival at TCC. Patients whose initial contact was with a general surgeon (OR: 7.6, 95% CI: 2.1, 27.6), primary care provider (OR: 12.2, 95% CI: 2.9, 51.0), or gynecologist (OR: 8.6, 95% CI: 1.4, 53.4) were significantly more likely to experience a delay in reaching the TCC as compared to those visiting a surgical oncologist. Overcoming health care system and patient navigation barriers in developing countries may reduce the time for breast cancer patients to reach a cancer center for early management.

Abstract
BACKGROUND Since 1990, the National Breast and Cervical Cancer Early Detection Program (BCCEDP) has funded breast cancer screening and diagnostic services for low-income, underinsured women. Case management was implemented in 2001 to address barriers to follow-up after an abnormal mammogram, and free treatment was introduced in 2004. However, the effect of these policies on timeliness of care has not been empirically evaluated. METHODS Among 2252 BCCEDP participants in Massachusetts during 1998 through 2007, we conducted a time-to-event analysis with prepolicy-postpolicy comparisons to examine associations of case management and free treatment with diagnostic and treatment delays (>60 days and >90 days, respectively) after an abnormal mammogram. RESULTS The proportion of women experiencing a diagnostic delay decreased from 33% to 23% after the introduction of case management (P < .001), with a significant reduction in the adjusted risk of diagnostic delay (relative risk [RR], 0.65; 95% confidence interval [CI], 0.53-0.79) that did not differ by race and ethnicity. However, case management was not associated with changes in treatment delay (RR, 0.93; 95% CI, 0.80-1.10). Free treatment was not associated with changes in the adjusted risk of diagnostic delay (RR, 0.61; 95% CI, 0.33-1.14) or treatment delay (RR, 0.77; 95% CI, 0.43-1.38) beyond improvements associated with case management. CONCLUSIONS Case management to assist women in overcoming logistic and psychosocial barriers to care may improve time to diagnosis among low-income women who receive free breast cancer screening and diagnostic services. Programs that provide services to coordinate care, in addition to free screening and diagnostic tests, may improve population health.

Abstract
BACKGROUND In the United States, and particularly in South Carolina, African-American women suffer disproportionately higher mortality rates from breast cancer than European-American women. The timeliness of patient adherence to the follow-up of mammographic abnormalities may influence prognosis and survival. The objective of the current investigation was to examine racial differences in the completion and completion time of a diagnostic workup after the finding of a suspicious breast abnormality. METHODS Study participants of the Best Chance Network, a statewide service program that provides free mammography screening to economically disadvantaged and medically underserved women, were included in the study. Racial differences in tumor characteristics and adherence to recommended workup were tested using chi-square tests and t tests. Logistic and Cox regression modeling was used to assess the relation between workup completion and other factors among African-American women and European-American women. RESULTS Completion of the workup was associated with the number of previous procedures and income, and no significant differences were noted by race. The amount of time to completion of the workup was influenced by previous procedures, income, and race. After accounting for completion time, African-American women were 12% less likely than European-American women to complete the recommended workup (hazard ratio, 0.88; P=.01). CONCLUSIONS The results from this study established a racial disparity in the time to completion of a diagnostic workup among Best Chance Network participants. These findings highlight the importance of understanding the factors associated with delays in and adherence to completing the recommended workup when breast abnormalities are detected in mammograms.

Abstract
PURPOSE/OBJECTIVES To identify factors associated with diagnostic delay after an incomplete or abnormal mammogram among women participating in a state mammography screening program. RESEARCH APPROACH Retrospective case-control design using bivariate and multivariate logistic regression analyses to explore the associations between age, race, ethnicity, marital status, breast cancer history, and self-reported breast symptoms and delay. SETTING A statewide program of free screening mammography for women who are under- or uninsured. PARTICIPANTS 11,460 women enrolled in a free, statewide screening program from 2002-2006. METHODOLOGIC APPROACH Using the Tennessee Breast and Cervical Cancer Screening Program database, further analyses were conducted. MAIN RESEARCH VARIABLES The outcome measure was delay in completion of all diagnostic tests and was defined as women who did not complete testing within 60 days. FINDINGS Thirty-seven percent of women required follow-up, and of a subset used in the analysis, 30% experienced delay of more than 60 days. Controlling for marital status, age, and breast cancer history, women who experienced delay were more likely to be African American versus Caucasian (odds ratio [OR] = 1.45, 95% confidence interval [CI] = 1.13, 1.85) or Hispanic (OR = 0.72, 95% CI = 0.55, 0.93) and to have self-reported breast symptoms (OR = 1.50, 95% CI = 1.27, 1.77). CONCLUSIONS In a sample of women with low income needing mammography follow-up, delay was associated with three intrapersonal variables, potentially reducing the effectiveness of mammography screening for women who were African American, or Hispanic, or had self-reported breast symptoms. INTERPRETATION Nurses providing cancer screening examinations are uniquely positioned to assess the knowledge, beliefs, and resources of women using the program and to navigate women through barriers to completion. Knowledge of factors associated with delay is valuable for planning interventions and allocating program resources.

Abstract
BACKGROUND Compared with white women, African-American (AA) women who are diagnosed with breast cancer experience an excess in mortality. To improve outcomes, the authors implemented community education and outreach initiatives in their cancer center, at affiliated primary care sites, and in the surrounding communities. They then assessed the effectiveness of these outreach initiatives and internal patient navigation on stage of diagnosis. METHODS This cross-sectional study was an analysis of all women with breast cancer who were diagnosed and/or treated in the years from 2001 through 2004. The outreach initiatives were implemented in 2001; 125 trained Community Health Advocates (CHAs) provided educational programs to the community, and Patient Navigators communicated directly with patients to encourage screening, diagnostic procedures, and treatment. RESULTS In total, 487 patients were diagnosed/treated from 2001 through 2004. Since 2001, there were 1148 community interventions by CHAs with an estimated program attendance of >10,000 participants. In the interval from 2001 through 2004, the proportion of stage 0 (in situ) breast cancers increased from 12.4% (n = 14) to 25.8% (n = 33; P < .005), and there was a decline in stage IV invasive breast cancers from 16.8% (n = 19) to 9.4% (n = 12; P < .05). CONCLUSIONS The outreach initiatives and internal patient navigation appear to have improved stage at diagnosis. To determine whether specific patients presented earlier as a result of specific community outreach initiatives, prospective work is underway to measure the effects of these interventions on potential stage migration. Similarly, prospective data are being collected to determine whether Patient Navigators influence treatment and appointment adherence as well as the underlying reasons for barriers to specific interventions in this underserved minority population.

Abstract
PURPOSE/OBJECTIVES To examine the delay in seeking treatment and worry experiences of African American women with breast cancer. DESIGN Descriptive, correlational. SETTING Urban northeastern United States. SAMPLE 60 African American women diagnosed with breast cancer. METHODS Consenting participants completed the worry subscale of the Ware Health Perception questionnaire and a Demographic and Illness-Related Information Sheet during a one-hour personal interview. Data analysis consisted of descriptive statistics and Pearson correlations. MAIN RESEARCH VARIABLES Delay in seeking treatment, worry about breast cancer and symptoms, and sociodemographic characteristics. FINDINGS Contrary to the literature, participants reported short patient and provider delay. As a result of little variability in delay, predicting those for whom worry was a deterrent or a motivator to seek prompt treatment was not possible. CONCLUSIONS Although delay does exist, African American women with sociodemographic characteristics similar to white women who do not delay are likely to have similarly short symptom durations. Further study to determine who is helped and who is hurt by worry and other possible intervening factors would be useful. Including biologic characteristics such as tumor staging and hormone receptor information in future studies would allow for a closer examination of stage at diagnosis and biologic influence. IMPLICATIONS FOR NURSING Interventions with African American women cannot assume that delay exists. Strategies that consider both individual and cultural group differences are essential to the early seeking of a diagnosis and treatment for breast cancer symptoms among African American women.

Abstract
PURPOSE Delays in the diagnosis of breast cancer are associated with advanced stage and poor survival, but the importance of the time interval between lumpectomy and initiation of radiation therapy (RT) has not been well studied. We investigated factors that influence the time interval between lumpectomy and RT, and the association between that interval and survival. PATIENTS AND METHODS We used data from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database on women aged 65 years and older, diagnosed with Stages I-II breast cancer, between 1991 and 1999. Among patients who did not receive chemotherapy, we studied factors associated with the time interval between lumpectomy and the initiation of RT, and the association of delay with survival, using linear regression and Cox proportional hazards modeling. RESULTS Among 24,833 women with who underwent lumpectomy, 13,907 (56%) underwent RT. Among those receiving RT, 97% started treatment within 3 months; older age, black race, advanced stage, more comorbidities, and being unmarried were associated with longer time intervals between surgery and RT. There was no benefit to earlier initiation of RT; however, delays >3 months were associated with higher overall mortality (hazard ratio, 1.92; 95% confidence interval, 1.64-2.24) and cancer-specific mortality (hazard ratio, 3.84; 95% confidence interval 3.01-4.91). CONCLUSIONS Reassuringly, early initiation of RT was not associated with survival. Although delays of >3 months are uncommon, they are associated with poor survival. Whether this association is causal or due to confounding factors, such as poor health behaviors, is unknown; until it is better understood, efforts should be made to initiate RT in a timely fashion.

Abstract
BACKGROUND Delay in the diagnosis of breast cancer is associated with worse stage distribution at diagnosis and decreased survival. However, the occurrence of delay in the delivery of adjuvant therapy and its impact on prognosis is not well understood. METHODS To investigate the timeliness of initiation of adjuvant chemotherapy following surgery for breast cancer, we used data from the Surveillance, Epidemiology, and End-Results (SEER)-Medicare database. Among women > or = 65 years diagnosed between 1992 and 1999 with stages I-II breast cancer, we used linear regression and Cox proportional hazards models to investigate the time intervals between surgery and initiation of adjuvant chemotherapy, factors associated with delay, and the effect of delay on survival. RESULTS Our sample consisted of 5003 women who received adjuvant chemotherapy. Of these, 47% initiated chemotherapy within 1 month, 37% between 1 and 2 months, 6% between 2 and 3 months and 10% >3 months (delay) following surgery. Delay was associated with increasing age, residing in a rural location, being unmarried, earlier tumor stage, hormone receptor positivity, mastectomy, and non-receipt of radiation therapy. Survival did not differ among patients who initiated chemotherapy within 1, 2, or 3 months after surgery. Delay beyond 3 months was, however, associated with increased disease-specific mortality (HR 1.69; 95% CI 1.31-2.19) and overall mortality (HR 1.46; 95% CI 1.21-1.75). CONCLUSIONS Among older patients, moderate delays in the receipt of adjuvant chemotherapy occur frequently, but long delays (>3 months) are uncommon. While early initiation of therapy is no benefit, significant delays are associated with increased mortality. Whether this reflects the medical impact of the delay of chemotherapy or factors associated with delay is unclear, but until this is clarified, patients should be encouraged to initiate treatment without significant delay.

Abstract
BACKGROUND The present study had two research questions. First, what is the average waiting time between diagnosis and treatment for Alberta women with breast cancer relative to Canadian Society for Surgical Oncology (CSSO) recommendations? Second, does patient age, cancer stage, patient community size, and year of diagnosis have a significant relationship to waiting time? METHODS The sample consisted of all Alberta women diagnosed with breast cancer between 1997 and 2000. Waiting time was defined as number of days between definitive diagnosis and treatment initiation. Multiple regression examined the relative influence of the predictor variables on waiting time. RESULTS There were 6,418 cases of breast cancer between 1997 and 2000. Mean waiting time was 20.2 days (SD 21.6) and median waiting time was 17 days. Longer waiting time was significantly associated with year of diagnosis (progressively longer from 1997 to 2000), patients younger than 70, and Stage 1 cancer. Waiting time increase from 1997 to 2000 appears to be due to increased demand for services without corresponding increases in resources. Less treatment delay for women older than 70 is due to more of these women being treated the same day they received their diagnosis. CONCLUSION Only 44% of women had a waiting time of 14 days or less as recommended by the CSSO. The number of women who will have to wait longer than recommended for treatment will likely increase without a significant increase in oncological resources. The basis for differences in waiting times as a function of age needs to be further investigated to ensure equitable access to care.

Abstract
This work combines and extends previous work on breast cancer screening models by explicitly incorporating, for the first time, aspects of the dynamics of health care states, program outreach, and the screening volume-quality relationship in a service system model to examine the effect of public health policy and service capacity decisions on public health outcomes. We consider the impact of increasing standards for minimum reading volume to improve quality, expanding outreach with or without decentralization of service facilities, and the potential of queueing due to stochastic effects and limited capacity. The results indicate a strong relation between screening quality and the cost of screening and treatment, and emphasize the importance of accounting for service dynamics when assessing the performance of health care interventions. For breast cancer screening, increasing outreach without improving quality and maintaining capacity results in less benefit than predicted by standard models.

Abstract
BACKGROUND Few studies have addressed the issue of whether delays in the interval between medical consultation and the diagnosis and treatment of breast carcinoma are greater for African American women than for white women. The authors examined differences with respect to these delays and analyzed the factors that may have contributed to such differences among women ages 20-54 years who had invasive breast carcinoma diagnosed between 1990 and 1992 and who lived in Atlanta, Georgia. METHODS A total of 251 African American women and 580 white women were interviewed and had their medical records reviewed. The authors estimated racial differences in delay times and used polytomous logistic regression to determine the contributions of various factors (socioeconomic and other) to these differences. RESULTS Although most women in both groups were treated within 3 months of initial consultation, 22.4% of African American women and 14.3% of white women had clinical delays of > 3 months. Compared with white women, African American women were more likely to experience delays in diagnosis and treatment. Access to care (as represented by method of detection and insurance status) and poverty index partially accounted for these differences in delay time; however, racial differences in terms of delayed treatment and diagnosis remained even after adjustment for contributing factors. CONCLUSIONS The findings of the current study suggest that among women ages 20-54 years who have breast carcinoma, potentially clinically significant differences in terms of delayed diagnosis and treatment exist between African American women and white women. Improvements in access to care and in socioeconomic circumstances may address these differences to some degree, but additional research is needed to identify other contributing factors.

Abstract
BACKGROUND Practice guidelines for breast cancer emphasize the importance of establishing an accurate diagnosis using a minimum number of procedures and selecting optimal treatment regimens. Understanding the determinants of waiting time is essential to develop optimum interventions to reduce delay. OBJECTIVES The purpose of this study is to estimate the extent to which variability in 1) the number of procedures before surgery and 2) waiting time from initial procedure to surgery are explainable by factors related to the woman, to the provider, and to the care setting. RESEARCH DESIGN Records of physicians' fee-for-service claims were obtained for 23,370 women undergoing breast cancer surgery in Quebec between 1992 and 1997. Multilevel logistic regression was used to determine predictors of having multiple procedures before surgery. Hierarchical linear regression models were used to identify predictors of waiting time, separately for women with lymph node involvement and without this involvement. RESULTS Overall, 23% of the women had 3 or more procedures before surgery with significant variation found across hospitals and surgeons. Number of procedures was a strong predictor of waiting time. Waiting time also varied by stage, age, comorbidity, a history of benign disease, surgical setting, calendar time, month of initial procedure, and hospital teaching status. CONCLUSION Although variability in waiting time was more strongly influenced by the characteristics of the women rather than by physician- or hospital-related factors, most variation remained unexplained by the factors included in this study. To reduce overall waiting time, strategies would need to be systemically applied.

Abstract
The earlier breast cancer can be diagnosed and treated, the better the odds for survival. The literature has shown many of the barriers to timely diagnosis are not individual behaviors but problems in delivery of health care. Case management has been suggested to facilitate diagnostic testing and treatment. Models of case management exist in other practice settings but have not always been rigorously described or evaluated. Determining optimal models for case management has been established federally as a research priority to ensure medically underserved women are promptly diagnosed and treated. One model has been developed and pilot-tested in this setting. This article will describe elements of case management and the characteristics of a publicly funded screening program that make use of case management to facilitate timeliness of diagnostic testing different from case management in other settings. These differences have implications for successfully implementing case management in public programs.

Abstract
PURPOSE Delaying the diagnosis and initiation of treatment of cancer is likely to result in tumor progression and a worse prognosis. We examined sources and consequences of provider delay among female breast cancer patients in a population-based study in Germany. PATIENTS AND METHODS Three hundred eighty women, who were ages 18 to 80 years and who had invasive breast cancer, were interviewed with respect to the diagnostic process. Provider delay was defined as time from first presentation to a health care provider until initiation of cancer treatment. RESULTS Median provider delay was 15 days and did not substantially differ by the specialty of first consulted physician. Delays in the diagnostic work-up were mainly because of erroneous initial suspicion of a benign breast disease or because of time constraints by patients or physicians. Provider delay over 3 months was found in 11% of all breast cancer cases and was associated with patient characteristics such as higher education (odds ratio [OR] = 2.6; 95% confidence interval [CI], 1.3 to 5.4), full-time employment (OR = 2.5; 95% CI, 1.1 to 5.5), family history of breast cancer (OR = 2.8; 95% CI, 1.2 to 6.2), and presenting with a non-breast symptom (OR = 4.3; 95% CI, 1.7 to 10.9). The association between duration of diagnostic work-up and stage at diagnosis was U shaped, with the highest proportions of metastasized breast cancer tumors among women with very short (< 7 days) or very long (> 3 months) duration. CONCLUSION Diagnostic work-up is within reasonably short time limits among most patients with breast cancer in Germany. Although the association between delay and tumor stage seems to be complex, any delay in diagnostic work-up should be kept to a minimum.

Abstract
OBJECTIVES This study examined the association between a residential area' socioeconomic status (SES), race, and advanced-stage breast cancer in New York City. METHODS The cross-sectional study design used breast cancer information for 37 921 cases diagnosed in New York City from 1986 to 1995. Residential education and income levels were based on the 1990 census and ascribed to each case by zip code. Associations between race, area SES, and advanced-stage breast cancer stage, and the interaction between race and SES, were evaluated in bivariate and multivariate analyses. RESULTS After adjusting for age and year at diagnosis, living in areas with lower levels of education and income increased the odds of presenting with advanced-stage breast cancer by 50% for Black women and by 75% for White women. No significant qualitative interaction was present between area SES and race. CONCLUSIONS This study confirmed independent racial and socioeconomic differences in the risk of advanced-stage breast cancer in a large and diverse population. The results emphasize the need to improve screening practices and clinical treatment in both high-risk populations and high-risk geographic areas.

Abstract
Delay in the diagnosis of breast cancer is an important cause of medical malpractice claims which if trends continue, will threaten healthcare budgets. Most malpractice claims are made by younger women. Delay is most frequently due to the physician failing to be impressed with the clinical findings, or to a false negative mammogram report. Diagnosis of breast cancer is more difficult in younger women, because of the poor sensitivity of diagnostic tests and the high prevalence of benign disease in this age group. Models of tumour growth suggest that the potential to metastasize may be present before the tumour is clinically detectable and that if the growth rate of a given tumour is constant, any clinical delay is a small proportion of the lifespan of the tumour. Patient delay is generally associated with more advanced lesions at presentation, but the effect of delay on survival or what period of delay is significant remains uncertain. Delay in the diagnosis of breast cancer is likely to cause the patient considerable anxiety, especially when the public understands that the aim of mammographic screening is to diagnose breast cancer at an early stage in order to effect a cure. For a plaintiff to successfully claim in court she must prove that she has suffered an injury, and that the injury was the result of negligent medical practice. It is easier to defend a case of delay in diagnosis if the documentation is in order and all the appropriate tests have been performed.

Abstract
Delay in the diagnosis and treatment of breast cancer diminishes a woman's chance of survival. How do women decide whether and when to seek an evaluation of breast symptoms that may signal breast cancer? Prior studies of African-American, white, and Latino women have described a number of critical factors associated with making the judgment to delay, but at this writing, there have been no studies factors influencing Chinese-American women. By means of focus group methods in English, Mandarin, and Cantonese, a sample of 45, predominantly first-generation Chinese-American women explained their understanding of breast cancer risk and their likelihood of delaying versus seeking evaluation of self-discovered breast symptoms. There was much congruence with the ideas of other American women despite the differing cultural heritage. Unique to these Chinese Americans was a sense of invulnerability to breast cancer, a linking of cancer to tragic luck, and the predominant likelihood of delay. To preserve modesty and to conserve wealth and time, many study participants favored using Chinese medicine and delaying Western therapies. This study suggests ways by which health care providers must approach guidelines for breast cancer early detection in this population.

Abstract
BACKGROUND Breast cancer is the second most common cause of cancer death in Thai women. Cancer registry data reveal a high prevalence of late-stage disease at diagnosis. The factors resulting in delay in Thailand have not yet been investigated. OBJECTIVES To determine the extent of, and the factors contributing to, delay in breast cancer care. DESIGN Women with breast cancer who were first treated at Songklanagarind Hospital between June 1994 and June 1996 were interviewed with retrospective chart audits of care. MEASURES Dependent variables included patient delay (symptom recognition to first care) and system delay (first care to treatment). Independent variables tested included demographic factors, help-seeking behavior, and cancer knowledge. Nonparametric rank sum tests were used for univariate analysis, and Cox regression was used for multivariate analysis. RESULTS Ninety-four cases were included in the study. The median patient and system delays were 4 weeks; 26.6% and 24.4% of patients, respectively, experienced patient and system delay >12 weeks. Only marital status (unmarried compared with married women) was significantly associated with patient delay (hazard ratio [HR] 2.78, 95% CI 1.23-6.25). Contacting a provincial hospital instead of a university hospital as first medical care (hazard ratio 2.50, 1.23-5.26), being given a diagnosis rather than being told nothing (HR 2.04, 1.14-3.57) and being given treatment rather than being immediately referred (HR 4.55, 2.22-9.09) were associated with system delay. CONCLUSIONS Patient delay and system delay in breast cancer care are important weaknesses of disease control in Thailand. Educational programs should target unmarried women, who are at higher risk of delay. System delay in hospitals outside the university needs to be improved by a good referral system.

Abstract
OBJECTIVES This study determined whether the incidence of diabetes is reduced among physically active older women. METHODS We assessed physical activity by mailed questionnaire and 12-year incidence of diabetes (ostensibly type 2 diabetes) in a cohort of 34257 women aged 55 to 69 years. RESULTS After adjustment for age, education, smoking, alcohol intake, estrogen use, dietary variables, and family history of diabetes, women who reported any physical activity had a relative risk of diabetes of 0.69 (95% confidence interval = 0.63, 0.77) compared with sedentary women. CONCLUSIONS These findings suggest that physical activity is important for type 2 diabetes prevention among older women.

Abstract
OBJECTIVES This study examined times to diagnosis and treatment for medically underserved women screened for breast cancer. METHODS Intervals from first positive screening test to diagnosis to initiation of treatment were determined for 1659 women 40 years and older diagnosed with breast cancer. RESULTS Women with abnormal mammograms had shorter diagnostic intervals than women with abnormal clinical breast examinations and normal mammograms. Women with self-reported breast symptoms had shorter diagnostic intervals than asymptomatic women. Diagnostic intervals were less than 60 days in 78% of cases. Treatment intervals were generally 2 weeks or less. CONCLUSIONS Most women diagnosed with breast cancer were followed up in a timely manner after screening. Further investigation is needed to identify and then address factors associated with longer diagnostic and treatment intervals to maximize the benefits of early detection.

Abstract
In women, breast cancer is the most frequent solid tumor and the second leading cause of cancer death. Differences in survival of breast cancer have been noted among racial/ethnic groups, but the reasons are unclear. This report presents the characteristics and the survival experience of four racial/ethnic groups and evaluates the effects of stage, age, histology, and treatment on survival time. The distributions of prognostic factors and treatment among racial/ethnic groups are compared using female breast cancer patients from two population-based registries in Southern California. The main end points are observed survival time and survival by cause of death. The Cox model is used to estimate the relative risk of death in three minority groups compared with non-Hispanic whites, while controlling for several covariates. Breast cancer cases included in this study were 10,937 non-Hispanic whites, 185 blacks, 875 Hispanics, and 412 Asians. The median follow-up period was 76 months (range: 48-132). The median age at diagnosis was 64 years among non-Hispanic whites, 55 years among Hispanics (p = 0.001), 52 years among blacks (p = 0.001), and 50 years among Asians (p = 0. 001). There was more localized disease among non-Hispanic whites (61. 4%) than among blacks (50.8%) and Hispanics (52.2%), but not compared to Asians (59.7%). After controlling for stage, age, histology, treatment, and registry, overall survival significantly differed between non-Hispanic whites and blacks [relative risk (RR) = 2.27, 95% confidence interval (95% CI) 1.82-2.84) and between non-Hispanic whites and Hispanics (RR = 1.18, 95% CI 1.04-1.34). The same results were found for breast cancer death in blacks (RR = 2.32, 95% CI 1.76-3.07) and Hispanics (RR = 1.28, 95% CI 1.10-1.50). We found no difference between Asians and non-Hispanic whites in overall and cancer-related survival. These results show that stage of disease, age at diagnosis, histologic features and treatment for breast cancer differed among racial/ethnic groups. Moreover, black women, in particular, and Hispanic women with breast cancer had a higher risk of death compared to non-Hispanic white women, even after controlling for prognostic factors. These findings underline the necessity of improved screening and access to appropriate treatment among minority women for breast cancer.

Abstract
BACKGROUND Delayed presentation of symptomatic breast cancer is associated with lower survival. Understanding of the factors that influence delay is important for the development of strategies to shorten delays. We did a systematic review to assess the quality and strength of evidence on risk factors for delays by patients and providers. METHODS We generated hypotheses about the relation between each putative risk factor and delay, against which we tested studies. We did searches to identify papers containing original data related to risk factors for delays by patients (n=86) and providers (n=28). We critically appraised the papers for inclusion in the review according to predefined criteria. The small number of studies of adequate quality did not allow formal meta-analysis. We therefore assigned strength of evidence according to a combination of the number and size of studies supporting, not supporting, or refuting the hypotheses. FINDINGS Most studies were deemed to be of poor quality and were excluded. Among 23 studies of adequate quality, however, there was strong evidence for an association between older age and delay by patients, and strong evidence that marital status was unrelated to delays by patients. Younger age and presentation with a breast symptom other than a lump were strong risk factors for delays by providers. Moderate evidence was shown for several other factors. INTERPRETATION The strength of the current evidence is inadequate to inform the development of specific strategies to shorten delays by patients or providers. Clarification of the findings of this review through a major programme of primary research is urgently required.

Abstract
In spite of cancer screening programs, women continue to present with advanced breast cancer. How do women decide whether and when to seek an evaluation for self-discovered symptoms? This study examined 104 narratives told by 80 Anglo-, Latina-, and African-American women who participated in 1 of 16 community-based focus groups. The women's narratives contained powerful thematic messages about breast cancer and their expected behavior in the event of a self-discovered breast symptom. Narrative explanations that predicted an increased likelihood of advanced disease at diagnosis included these factors: incorrect symptom attributions and risk estimations; reluctance to consider the threat posed by the symptom; failure to tell another person about the symptom; and expectations of abandonment by male partners, deportation, prejudice, and refusal of treatment due to poverty. Stories of advanced breast cancer also told of reliance on alternative healing, concerns about overwhelming family resources, and extreme modesty that inhibited obtaining a physical examination. Interventions aimed at earlier detection of breast cancer must connect with the beliefs and assumptions embedded in these narratives, provide pragmatic solutions for perceived constraints on seeking evaluations of self-discovered symptoms, and explore the use of community narratives to confirm the value of early detection of breast cancer.

Abstract
A case-control study was conducted to ascertain occurrence of advanced- and early-stage breast cancer, use of mammography, and the relationship between the two. All women with stage III/IV breast cancer (N = 46) were matched to two controls (stage 0/I and stage II) by year of diagnosis and age. Matched-pair analyses assessed antecedent use of screening mammography. Results indicated that advanced-stage patients were significantly less likely than their stage 0/I counterparts to have had antecedent screening within 13 months of diagnosis [chi2: 5.78; OR: 6.0; p < 0.05]. Cases compared with stage II controls did not differ statistically. Efforts should focus on increasing mammography in currently targeted age groups. Considerations might be toward extending regular screening for women 40 to 49 and over 75.

Abstract
BACKGROUND Breast cancer survival has been shown to be significantly less among black women than white women. The reason for this difference in survival is unclear. METHODS Data were obtained retrospectively on 439 women seen between 1985 and 1993 based on a detailed chart audit. The impact of race and several known prognostic factors on overall survival, time to relapse, and survival after relapse were studied. RESULTS Black women with breast cancer were found to have a greater risk of recurrence, shorter overall survival, and shorter survival after relapse than did white women. Black patients were found to be younger and have higher stage of disease and lower hormone receptor levels than were white patients. After adjustment for menopausal status and disease stage, a significant independent effect of race was observed on overall survival but not risk of recurrence. In multivariate analysis, a significant interaction was observed between race and age in some models. Survival after recurrence of disease was lower among black than white women after adjustment for menopausal status and estrogen receptor level. CONCLUSION Black women experience shorter survival times than do white women, including a shorter survival time after disease recurrence. Breast cancer in black women is associated with younger age, higher stage at presentation, and low hormone receptor levels. After adjustment for known prognostic factors, race remains a significant independent predictor of breast cancer survival.
