Abstract
BACKGROUND Postmastectomy breast reconstruction (BR) has been shown to provide long-term quality of life and psychosocial benefits. Despite the policies initiated to improve access to BR, its delivery continues to be inequitable, suggesting that barriers to access have not been fully identified and/or addressed. The purpose of this study was to assess the influence of geographic location, socioeconomic status, and race in access to immediate BR (IBR). METHODS An institutional review board-approved observational study was conducted. All patients who underwent breast cancer surgery from 2014 to 2019 were queried from our institutional Breast Cancer Registry. A geographical analysis was conducted using demographic characteristics and patient's ZIP codes. Euclidean distance from patient home ZIP code to UPMC Magee Women's Hospital was calculated, and χ2, Student t test, Mann-Whitney, and Kruskal-Wallis tests was used to evaluate differences between groups, as appropriate. Statistical significance was set at P < 0.05. RESULTS Overall, 5835 patients underwent breast cancer surgery. A total of 56.7% underwent lumpectomy or segmental mastectomy, and 43.3% underwent modified, total, or radical mastectomy. From the latter group, 33.5% patients pursued BR at the time of mastectomy: 28.6% autologous, 48.1% implant-based, 19.4% a combination of autologous and implant-based, and 3.9% unspecified reconstruction. Rates of IBR varied among races: White or European (34.1%), Black or African American (27.7%), and other races (17.8%), P = 0.022. However, no difference was found between type of BR among races (P = 0.38). Moreover, patients who underwent IBR were significantly younger than those who did not pursue reconstruction (P < 0.0001). Patients who underwent reconstruction resided in ZIP codes that had approximately US $2000 more annual income, a higher percentage of White population (8% vs 11% non-White) and lower percentage of Black or African American population (1.8% vs 2.9%) than the patients who did not undergo reconstruction. CONCLUSIONS While the use of postmastectomy BR has been steadily rising in the United States, racial and socioeconomic status disparities persist. Further efforts are needed to reduce this gap and expand the benefits of IBR to the entire population without distinction.

Abstract
BACKGROUND This study seeks to understand the breast cancer treatment patterns and experiences of women enrolled in Georgia's Breast and Cervical Cancer Prevention and Treatment Act program, the Women's Health Medicaid Program (WHMP), and whether these experiences vary by race or location. METHODS We conducted a mixed-methods analysis of WHMP breast cancer enrollees by race and urban/rural location. Quantitative analysis used a hazard rate model approach to identify differences in the timing of diagnosis, enrollment into Medicaid, and various modalities of treatment for 810 enrollees. Qualitative analysis used a systematic retrieval and review of coded data from 34 in-depth disease life history interview transcripts to a complete, focused analysis of enrollees' cancer treatment experiences. FINDINGS African-American women began treatment, on average, 6 days later after diagnosis than White women, driven by delays of one month among African-American women with late-stage cancers. This time delay for African-American women was not significant on multivariate analysis of time from enrollment to treatment. Once enrolled in WHMP, women reported gaining access to equitable breast cancer treatment regardless of race or location, with the exception of breast reconstruction, for which some women in our sample reported barriers to care. CONCLUSIONS The equitable access to cancer treatment and other health services provided by WHMP to low-income, uninsured women in Georgia with breast cancer makes it a critical health care safety net program in Georgia, the need for which will continue through the implementation of the Affordable Care Act.

Abstract
BACKGROUND The disparity in breast cancer mortality rates among white and black US women is widening, with higher mortality rates among black women. We apply functional time series models on age-specific breast cancer mortality rates for each group of women, and forecast their mortality curves using exponential smoothing state-space models with damping. MATERIALS AND METHODS The data were obtained from the Surveillance, Epidemiology and End Results (SEER) program of the US [1]. Mortality data were obtained from the National Centre for Health Statistics (NCHS) available on the SEER*Stat database. We use annual unadjusted breast cancer mortality rates from 1969 to 2004 in 5-year age groups (45-49, 50-54, 55-59, 60-64, 65-69, 70-74, 75-79, 80-84). Age-specific mortality curves were obtained using nonparametric smoothing methods. The curves are then decomposed using functional principal components and we fit functional time series models with four basis functions for each population separately. The curves from each population are forecast and prediction intervals are calculated. RESULTS Twenty-year forecasts indicate an overall decline in future breast cancer mortality rates for both groups of women. This decline appears to be steeper among white women aged 55-73 and black women aged 60-84. For black women under 55 years of age, the forecast rates are relatively stable indicating there is no significant change in future breast cancer mortality rates among young black women in the next 20 years. CONCLUSION White women have smooth and consistent patterns in breast cancer mortality rates for all age-groups whereas the mortality rates for black women are much more variable. The projections suggest, for some age groups, black American women may not benefit equally from the overall decline in breast cancer mortality in the United States.

Abstract
Women of African descent have a lower incidence of breast cancer than their white counterparts; however, the overall age-adjusted breast cancer mortality rates are higher. They also present at a younger age, and have more advanced disease that exhibits poor prognostic features including significantly larger tumors of higher grade, higher rates of estrogen receptor and progesterone receptor negativity and a higher rate of p53 mutations and HRAS1 proto-oncogene expression, all of which confer a poor prognosis. While there are many possible contributory factors to the discrepancies in outcome in women of African descent, there is no satisfactory explanation as to why women of African origin tend to present at a younger age with hormone receptor-negative tumors and more adverse prognostic features.

Abstract
BACKGROUND Multiple factors may influence whether patients undergo immediate breast reconstruction along with mastectomy for breast cancer. The authors investigated whether ethnicity was an independent predictor of immediate breast reconstruction. METHODS The authors identified 1004 patients who underwent mastectomy for breast cancer during the period 2001-2002. The rates of immediate reconstruction among different ethnicities were evaluated using the chi-square test. Logistic regression was used to adjust for covariates, including age and disease stage. Medical records were analyzed to identify factors that influenced each patient's decision for or against immediate breast reconstruction. RESULTS Three hundred seventy-six women (37.5%) underwent immediate breast reconstruction: This included 20.2% of African-American women, compared with 40.0% of white women, 42.0% of Hispanic women, 42.2% of Asian women, and 10.0% of Middle Eastern women (P < 0.001). The unadjusted odds ratio (OR) for immediate reconstruction for African-Americans versus whites was 0.38 (95% confidence interval [95% CI], 0.23-0.63; P < 0.001). After multivariate analysis, this disparity persisted, with an adjusted OR of 0.34 (95% CI, 0.18-0.62; P = 0.001). Asian women had lower rates of immediate reconstruction compared with white women (adjusted OR, 0.50; 95% CI, 0.24-1.04; P = 0.06). Hispanic women did not have immediate reconstruction rates that differed significantly from white women. Middle Eastern women had lower rates of immediate reconstruction compared with white women (adjusted OR, 0.08; 95% CI, 0.02-0.38; P = 0.002), but they had a corresponding increase in the rate of delayed reconstruction. In a stepwise analysis of the decision pathway to immediate reconstruction, it was found that African-American women were less likely to be offered referrals for reconstruction, were less likely to accept offered referrals, were less likely to be offered reconstruction, and were less likely to elect reconstruction if it was offered. CONCLUSIONS African-American women underwent immediate breast reconstruction at significantly lower rates compared with white women, Hispanic women, and Asian women. After adjusting for covariates, including age and disease stage, African-American women and Asian women had lower rates of reconstruction compared with white women. The factors that contribute to these differences warrant further study.

Abstract
PURPOSE To evaluate the patterns of failure, relapse-free survival and overall survival among African American breast cancer patients younger than 40 years. PATIENTS AND METHODS We retrospectively reviewed the records of 124 African American breast cancer patients younger than 40 years who were registered with the Howard University Cancer Center Database between 1990 and 1999. One hundred and six patients were found eligible and subsequently included in this analysis. Ninety-eight percent of these patients were pre-menopausal and 30% had a documented family history of breast cancer. Patient distribution per stage is as follows: 19%, stage I; 61%, stage II; 16%, stage III and 4%, stage IV. Surgery was a component of treatment for 98% of the patients. Forty-six percent underwent mastectomy, 47% had breast-conserving surgery and 5% underwent biopsy only. Fifty-nine percent of the patients received adjuvant radiation and 56% were also treated with adjuvant chemotherapy. Median follow-up was 35 months (range of 4-126 months). RESULTS Locoregional only first failure rate was 6% while systemic failure occurred in 20% of these patients. Among 17 stage III patients, 50% developed distant metastasis. The 5-year overall survival for these patients was 73%, with relapse-free survival being numerically similar. Patients with early stage disease, stages I and II, were noted to have 5-year overall survival rates of 100 and 78-83%, respectively. Those who presented with stage III or stage IV disease had dismal 5-year overall survival rates of 25-29 and 0%, respectively. Multivariate analysis using the Cox proportional hazard model identified the presence of metastasis as a factor that significantly affects survival in these young African American females. CONCLUSION These results show that African American females younger than 40 years with early stage breast cancer have local control and survival rates comparable to that of the general population. In contrast, young African American females in this study, with stages III and IV disease, appear to suffer a worse prognosis despite standard therapy. A larger series of young African American females with breast cancer, followed for a longer period of time, will be required to confirm a negative trend in survival.

Abstract
BACKGROUND Breast cancer mortality rates are higher among African-American women compared with white American women, yet little is known regarding ethnicity-related variation in patterns of primary surgical treatment, locoregional recurrence rates, and response to induction chemotherapy. METHODS The available literature was reviewed to evaluate outcome from breast-conservation therapy in African-American women and response rates to systemic therapy. RESULTS Breast-conservation therapy appears to be underused among African-American women, a pattern that is noted also among white women with breast carcinoma. Higher rates of locoregional recurrence are seen among African-American women regardless of whether they receive breast-conserving treatment or undergo mastectomy, and this appears to be a function of primary tumor biology. Response rates to appropriately delivered systemic therapy are similar for African-American patients and white patients. CONCLUSIONS Despite the apparent increased aggressiveness of disease seen in African-American women with breast carcinoma, patterns of response to local and systemic therapy are similar to the patterns seen in white women with breast carcinoma.

Abstract
BACKGROUND Whether African-American women have biologically more aggressive breast carcinoma compared with white women and whether race acts as a significant independent prognostic factor for survival have not been determined. Alternatively, race merely may be a surrogate for socioeconomic status (SES). METHODS A literature review was performed of clinical trials and retrospective studies in the U.S. that compared survival between white women and black women with breast carcinoma after adjustment for known prognostic factors (patient age, disease stage, lymph node status, and estrogen receptor status) to assess the impact of race and SES. RESULTS Single institutional and clinical studies suggest that, when black patients are treated appropriately and other prognostic variables are controlled, their survival is similar to the survival of white patients. Twelve retrospective studies and 1 analysis of a clinical trial included SES and race as variables for survival. Only three of those studies revealed race as a significant prognostic factor for survival after adjusting for SES. CONCLUSIONS SES replaces race as a predictor of worse outcome after women are diagnosed with breast carcinoma in many studies. However, black women present with more advanced disease that appear more aggressive biologically, and they present at a younger age compared with white women. Further research should be conducted concerning the precise elements of SES that account for the incidence of breast carcinoma, age at diagnosis, hormone receptor status, and survival to devise better strategies to improve outcome.

Abstract
Observed variations in breast cancer survival by racial/ethnic background have been attributed to many factors, including differences in clinical and pathologic disease features at diagnosis and economic resource inequities that may affect treatment access and quality. In this report, we examine outcomes for African-American and Caucasian breast cancer patients participating in selected randomized clinical trials of the National Surgical Adjuvant Breast and Bowel Project (NSABP) to determine whether prognosis or efficacy of systemic adjuvant therapy differed between these groups. Randomized clinical trials offer the advantages of a similar disease stage and a uniform treatment plan for all participants. Patients from four NSABP trials enrolling patients from 1982 through 1994 with axillary lymph node-negative disease (543 African-American and 7582 Caucasian) and three trials enrolling patients from 1984 through 1991 with axillary lymph node-positive disease (548 African-American and 4986 Caucasian) were included. Disease-free survival (DFS), which was defined as time on study free of breast cancer recurrence, second primary cancer, or death preceding these events, and survival risk ratios (RRs) with two-sided 95% confidence intervals (CIs) for African-Americans versus Caucasians were computed from Cox proportional hazards models that included relevant prognostic covariates. Treatment benefits for the therapies evaluated in these trials were estimated separately for African-Americans and for Caucasians. Among patients with lymph node-negative disease, African-Americans had similar DFS rates to Caucasians (African-American/Caucasian RR = 1.06, 95% CI = 0.92 to 1.23) but had modestly greater mortality rates (RR = 1.21, 95% CI = 1.01 to 1.46). Among lymph node-positive patients, DFS was similar (RR = 1.04, 95% CI = 0.93 to 1.17) and survival was again less favorable for African-Americans (RR = 1.18 95% CI = 1.03 to 1.34). Survival excluding deaths most likely attributable to causes other than cancer was similar between African-Americans and Caucasians (RR = 1.08 [95% CI = 0.88 to 1.33] for lymph node-negative patients and RR = 1.09 [95% CI = 0.96 to 1.25] for lymph node-positive patients). Among lymph node-negative and lymph node-positive patients, African-Americans and Caucasians realized comparable benefit from either the addition of chemotherapy or tamoxifen to surgery alone or the addition of chemotherapy to tamoxifen. In summary, African-American women and Caucasian women who were diagnosed at a comparable disease stage and were similarly treated tended to experience similar breast cancer prognosis. However, a mortality deficit persisted for African-American women relative to Caucasian women, which may be in part due to greater mortality from noncancer causes among African-Americans. Benefit from systemic adjuvant therapy for recurrence and mortality reduction was comparable between African-Americans and Caucasians. This study and investigations in other health-care settings suggest that African-American women and Caucasian women with breast cancer derive a similar benefit from systemic adjuvant therapy when it is administered in accordance with their clinical and pathologic disease presentation.

Abstract
Studies indicate ethnic differences in incidence, mortality, and survival rate of breast cancer. Despite the low incidence rate of breast cancer among the Korean population, Koreans are reported to be less likely to survive breast cancer. In this article, using a feminist perspective, the reasons why Korean women have been reported to be less likely to survive breast cancer are analyzed through a critical review of research among Korean women. A total of 469 studies (145 unpublished master's theses and doctoral dissertations and 324 articles published in South Korea and in the United States) were reviewed, analyzed, and critiqued in terms of biases present in the research process. Through a feminist critique of the literature, four possible reasons are proposed: androcentric views and assumptions underlying the research, modesty issues imbedded in Korean culture, the victim-blaming tendency of Korean culture, and intense emotions without adequate support.

Abstract
BACKGROUND African-American women have a lower survival rate than white women following a diagnosis of invasive breast cancer. Limited information is available regarding the impact of race on results of breast conservation therapy (BCT). METHODS Local recurrence rates were compared in 71 African-American patients (73 breasts) and 204 white patients (208 breasts) with stage I and II breast cancer treated with BCT. RESULTS Overall 5-year actuarial recurrence rates were 13% in African-Americans and 4% in whites (P = 0.075). These rates were 9% and 4%, respectively, if patients with local skin/soft tissue recurrences were excluded (P = 0.587). Exclusion of these skin/soft tissue failures eliminated any significant difference seen in recurrence between stage II African-American and white patients (P = 0.163). African-American women had less favorable recurrences, including tumor in more than one quadrant or local skin/ soft tissue involvement (P = 0.001). CONCLUSIONS Overall actuarial recurrence rates were slightly higher, but not significantly different, in African-American and white women following BCT. A much less favorable pattern of local recurrence was seen in the African-American patients (P = 0.001), which may represent the presence of more biologically aggressive tumors in these women.

Abstract
RATIONALE AND OBJECTIVES The authors determined the mammographic appearance of breast carcinoma in African-American women and compared it with that in a white cohort. MATERIALS AND METHODS The authors reviewed the mammograms, clinical records, and pathology records of 97 consecutive African-American women with 100 confirmed breast cancers and 110 white women with 111 confirmed breast cancers. RESULTS The mammograms obtained in African-American women were positive in 94 cases (94%), and those obtained in white women were positive in 99 cases (89%). Forty-seven percent of malignancies in African-American women appeared as calcifications, alone or with a mass, and 41% appeared as a mass only. There was no statistically significant difference in the frequency of these two findings between the African-American and the white populations. There was no statistically significant difference in the breast parenchymal pattern between the two groups. The most common tumor location in both races was the upper outer quadrant. CONCLUSION Breast carcinoma in African-American women is similar to that in white women in terms of mammographic appearance, location, and breast density. The mammographic appearance should not be an impediment to the detection of breast cancer in African-American women.

Abstract
BACKGROUND Breast cancer mortality is significantly higher among black patients compared to white patients. Black women are reportedly at increased risk for early-onset breast cancer. Our goal was to evaluate stage distribution relative to age among black and white breast cancer patients in an institution with a relatively high minority patient population. METHODS We evaluated 425 patients diagnosed with breast cancer between 1990 and 1994: 56% white, 34% black, the remainder were other ethnicities. Patients were stratified by age: under 50 years versus 50 and older. Socioeconomic status was estimated by utilization of medical care in the private-practice setting versus the public clinic. RESULTS Significantly more black patients were younger at diagnosis compared to white patients (32% vs. 20%; p = 0.008). There was a significantly more advanced stage distribution among the younger black patients, but not among the older black patients. Most of the black and white patients received private-practice care. CONCLUSIONS These age-related differences in breast cancer stage distribution between black and white patients (which appeared independent of socioeconomic status) indicate that more aggressive screening and public education programs directed toward younger black women is warranted, and they lend support to the possibility of ethnicity-related variation in primary tumor biology.

Abstract
This study examined the effect of race, income, and education on perceived susceptibility to and control over breast cancer, perceived benefits of and barriers to mammography, and knowledge about breast cancer and mammography use, in addition to determining if predictors for mammography use differed between races. Self-reported mailed survey data were obtained from a convenience sample of 1083 church women (78% Caucasian, 22% African-American) > or = 50 years with no history of breast cancer. ANOVA identified higher susceptibility and lower knowledge scores for African-American women; higher knowledge scores for upper income women of both races; interactions between race and income for benefits and perceived control; and interactions between race and education for barriers. African-American women were more likely to regard fear of radiation as a barrier to mammography (OR = .34; CI = .20, .57) and were more likely to worry about getting breast cancer (OR = .50; CI = .30, .82). Caucasian women were more likely to regard cost as a barrier (OR = 2.36, CI = 1.27, 4.40). For both races, variables predictive of ever having a mammogram were perceived control (White: OR = .69, CI = .54, .88; Black: OR = .50, CI = .38, .92), perceived barriers (White: OR = .88, CI = .83, .95; Black: OR = .75, CI = .64, .88), and knowledge (White: OR = 1.18, CI = 1.04, 1.33; Black: OR = 1.28, CI = 1.02, 1.61). Perceived benefits was predictive only for Caucasians (OR = 1.71, CI = 1.42, 2.06). Racial differences in perceived barriers to mammography and findings about the knowledge differences related to race, income, and education provide direction for health education efforts. The significance of cost factors for Caucasian and low-income women suggest that access barriers remain despite increased use of mammography.

Abstract
BACKGROUND A disparity in breast carcinoma survival between African-American and white women has been noted over the past several decades. A major factor implicated in this disparity is stage of disease at diagnosis. In this study, survival and related endpoints were examined among African-American women and white women with lymph node negative breast carcinoma who participated in two randomized clinical trials of the National Surgical Adjuvant Breast and Bowel Project (NSABP). METHODS Patients from two studies, one conducted among patients with estrogen receptor (ER) negative tumors and the other among patients with ER positive tumors, were included. Study goals were to determine whether African-Americans and whites had comparable outcomes, accounting for ER status and differences in patient characteristics at diagnosis, and to determine whether treatment response was similar for African-Americans and whites. RESULTS Five-year survival rates were 83% for African-Americans and 85% for whites among ER negative patients, and 93% for African-Americans and 92% for whites among ER positive patients. Rates of disease free survival (DFS) (i.e., time to disease recurrence, second primary cancer, or death) were 71% for African-Americans and 74% for whites at 5 years among ER negative patients, and 81% for African-Americans and 80% for whites among ER positive patients. African-Americans tended to have less favorable baseline prognostic characteristics. Adjusted relative risk (RR) estimates indicated similar prognosis for African-Americans compared with whites for mortality (African-American/white RR = 1.02 with 95% confidence interval [CI], 0.66-1.56 among ER negative patients; RR = 1.14 with 95% CI, 0.84-1.54 among ER positive patients) and DFS (RR = 0.98 with 95% CI, 0.70-1.37 for ER negative patients; RR = 0.96 with 95% CI, 0.75-1.22 for ER positive patients). Estimated percent reductions in DFS events for patients receiving adjuvant therapy were 32% for ER negative African-Americans, 36% for ER negative whites, 20% for ER positive African-Americans, and 39% for ER positive whites. CONCLUSIONS African-American and white patients with localized breast carcinoma had similar outcomes and benefited equally from systemic therapy. These results suggest that early detection and appropriate therapy among African-American patients could result in a reduction in the current disparity in breast carcinoma mortality between African-Americans and whites.

Abstract
This paper analyzes in-depth interviews with 26 black women who entered the medical system in rural North Carolina with advanced breast disease. In these narratives, women draw on multiple sources of knowledge in order to come to terms with the diagnosis of breast cancer--a biomedically-defined disease that they often refuse to acknowledge or accept. The analysis demonstrates how women relate the meaning of their individual episodes of illness to one or more of the following sources of knowledge: an indigenous model of health emphasizing balance in the blood, popular American notions about cancer, and particular biomedical conceptions about breast disease and its treatment. These narratives provide an important window into the processes involved when individuals attempt to adapt personal experience to pre-existing cultural models, modify such models in the light of new information, and confront conflicts in their own interpretations of the meaning of a single episode of illness.

Abstract
BACKGROUND The National Cancer Institute Black/White Cancer Survival Study began patient accrual in 1985 and was designed to investigate factors that might contribute to the observed racial differences in survival for cancer of the breast, uterine corpus, colon, and bladder. METHODS To determine whether there were racial differences in treatment in a clinically homogeneous set of patients, 305 (25%) of the 1222 women in this study with Stage II node-positive (N+) breast cancer were evaluated. RESULTS Patient characteristics for blacks and whites were similar for age, metropolitan area of residence, tumor size, extent of nodal involvement, and steroid receptors. Differences in histologic findings, tumor grade, and nuclear atypia were observed. Blacks had a higher frequency of comorbid conditions, especially hypertension (P < 0.00001). Fewer blacks underwent breast-conserving surgery (P = 0.004). In a multivariate analysis, race was no longer a significant factor in the selection of primary treatment, but education and metropolitan area of residence remained significant. Blacks and whites received similar postoperative systemic therapy, with combination chemotherapy (cyclophosphamide, methotrexate, and 5-fluorouracil) and tamoxifen, the most common cytotoxic and endocrine therapies used. CONCLUSIONS The National Cancer Institute consensus statement concerning adjuvant therapy for breast cancer was published in the middle of the 2-year period that study cases were accrued, and treatment plans in this study generally agreed with consensus guidelines. Should survival differences in black and white patients with Stage II N+ disease in this study be found, they are unlikely to be attributable to differences in initial or postoperative treatment.

Abstract
Between 1977 and 1986, 75 black and 615 white women with American Joint Committee (AJC) Stages I and II breast cancer were treated with excisional biopsy, axillary dissection, and radiation therapy for breast conservation. Cyclophosphamide, methotrexate, and 5-fluorouracil, with and without prednisone and tamoxifen, was given to 92% of premenopausal, 83% of perimenopausal, and 63% of postmenopausal node-positive women; 20 of 106 (19%) postmenopausal node-positive women received tamoxifen only. The clinical characteristics of the similarly treated patients were compared. The 5-year actuarial local only first failure rate was 5% for black women and 6% for white women (P = 0.53). Regional only failure as the first site of failure was 9% for blacks versus 1% for whites (P = 0.002), with regional recurrence as any component of first failure being 16% for blacks and 4% for whites (P = 0.001). The supraclavicular fossa was identified as the primary site of regional recurrence in black patients with either pathologically positive or negative axillae. Distant metastases as the only site of first failure were significantly greater in the black population with a 20% 5-year actuarial failure rate versus 11% in white patients (P = 0.01). The 5-year actuarial overall survival for the black patients was 82% versus 91% for the white patients (P = 0.01), with no-evidence-of-disease (NED) survival being 64% and 83% (P = 0.0002) and relapse-free survival (RFS) being 61% and 77% (P = 0.01), respectively. Black patients younger than 40 years of age or with pathologically positive axillary nodes had significantly worse NED, RFS, and overall survival compared with similarly staged white patients. Cosmetic results were analyzed at 3 and 5 years after completion of therapy. Although significantly fewer black patients had an excellent-to-good cosmetic result at 3 years compared with white patients, the results were not significantly different at 5 years. These results show that appropriately selected black patients with early stage breast cancer have excellent local control after conservative surgery and radiation therapy and should continue to be offered breast preservation as an alternative to mastectomy. Patterns of failure, however, demonstrated higher regional and distant recurrence rates and lower NED, RFS, and overall survival rates in most subsets of black patients reviewed.

Abstract
Prior studies have shown that black patients with breast cancer have poorer survival times compared with white patients even when adjusted for stage. Seventy-four black patients treated on six Piedmont Oncology Association (POA) protocols were compared with 74 randomly selected white patients treated with the same protocols to determine if race had any independent effect on response, time to progression, or survival time. Patients were evenly matched for pretreatment characteristics with the exception that white patients had a significantly higher percentage of bone metastases and significantly less skin involvement. Response rates and median time to progression were similar for black patients and white patients at 31% and 25%, and 9.3 and 9.1 months, respectively. Black patients had poorer survival times even when adjusting for covariables; median survival time was 14.3 months for black patients and 20.3 months for white patients (P less than 0.05). The reason for this survival difference in Stage IV patients is unclear, but is unlikely to be related to treatment. Additional research in this area will be necessary to resolve this issue.
