RESUMO

BACKGROUND: Although the incidence of breast cancer is highest in White women, Black women die at a higher rate. Our aim was to compare the relative association between race/ethnicity and socioeconomic status on breast cancer mortality. METHODS: We identified female breast cancer patients diagnosed between 2007 - 2011 and followed through 2016 in the SEER database. Patients were grouped into socioeconomic quartiles by a prosperity index. The primary outcome of interest was 5-year cancer-specific survival. RESULTS: A total of 286,520 patients were included. Five-year survival was worst for Black women compared to other races/ethnicities in each socioeconomic quartile. When compared to White women in the lowest quartile, Black women in the lowest quartile, 2nd quartile, and 3rd quartile experienced the lowest 5-year survival rates (Hazard ratio 1.33, 1.23, 1.20; P < 0.01). CONCLUSION: Regarding cancer mortality, only in the most prosperous quartile do Black women achieve a similar outcome to the poorest quartile White women.

RESUMO

INTRODUCTION: Thyroid cancer incidence has increased substantially in the past 4 decades, estimated at 3.5% annually. Incidence is highest in white patients, yet black patients have the worst survival. Racial/ethnic differences in presentation and outcomes are hypothesized to be a result of differences in access to care. Analyses delineating the relative contribution of access to racial/ethnic survival disparities are scarce. We aimed to explore the association of delay in access to care and early/increased detection with racial/ethnic disparities in thyroid cancer survival. METHODS: The Surveillance, Epidemiology, and End Results (SEER) database was queried from 2007 to 2011 for patients with a first primary thyroid cancer diagnosis and up to 5 years of follow-up. Composite scores were generated from county-level variables to capture socioeconomic status and screening habits. Kaplan-Meier analysis and Cox proportional hazards models were utilized for survival analysis. RESULTS: We identified 46,970 patients (67% white, 7% black, 15% Hispanic, 10% Asian or Pacific Islander, and 1% unknown/other). Compared to white patients, black, Hispanic, and Asian or Pacific Islander patients were more likely to present with distant disease (3% vs 5%, 5%, and 6%, respectively; P < .001). After adjusting for sex, age, stage, subtype, tumor size, surgery, radiation, socioeconomics, and screening habits, black patients were the only race/ethnicity found to have increased odds of 5-year mortality compared to white patients (24%, P < .001). CONCLUSION: Thyroid cancer survival is worst for black patients regardless of socioeconomic status or screening habits. Racial/ethnic disparities in survival are not attributable to early detection alone.

RESUMO

Of the four subtypes of cutaneous melanoma, acral lentiginous melanoma (ALM) is atypical in its presentation. ALM is a rare melanoma subtype that presents on the volar surfaces of the hand and foot. The difficulty of making an early diagnosis of ALM is highlighted by the case seen in our institution. The dire prognosis associated with ALM is postulated to be not only related to its destructive nature, but also due to a lack of patient awareness and vigilance, inadequate physician awareness, and disparity in healthcare access. We present this as a unique account of an ALM lesion in a 76 year old African-American male presenting originally in the left foot that went misdiagnosed for several years. The original lesion was considered to be an ulcerating left great toe lesion with signs typical of osteomyelitis. These clinical findings were corroborated by radiological x-ray evidence. Upon amputation and biopsy for suspected worsening osteomyelitis five years later, the pathological diagnosis of melanoma was finally made.

RESUMO

The objective of this study was to identify predictors of self-reported family health history of breast cancer in an ethnically diverse population of women participating in a breast cancer screening program. Participants completed a self-administered questionnaire about their demography, health, breast health and family health history of breast cancer. The association between family health history of breast cancer and categorical variables were analyzed using the T test, chi square, and multi-nominal logistic regression. Those who were least likely to report a family history of cancer were African Americans (p = 0.02), and immigrant women from South America (p < 0.001) and Africa (p = 0.04). However, 34.4 % reported having a second-degree maternal relative with breast cancer compared to 6.9 % who reported having a second degree paternal relative with breast cancer. Therefore, there is a need to increase efforts to educate families about the importance of collecting and sharing one's family health history.

RESUMO

Expression of estrogen receptor (ER), progesterone receptor (PR), and the human epidermal growth factor receptor 2 (HER2) can subdivide breast carcinomas into clinically meaningful classes. Cancers lacking expression of all three of these receptors (triple-negative breast cancer; TNBC) is of particular interest for molecular research because these tumors currently have no effective targets for therapy. Furthermore, TNBCs are relatively more prevalent among African-American women and can account for some of the health disparities associated with breast cancer. We approached a molecular understanding of how TNBC differs from ER(+) breast cancer through a comprehensive gas chromatography (GC)-mass spectrometry (MS) and liquid chromatography (LC)/MS/MS-based and unbiased metabolomic analysis of a series of breast carcinomas from African-American patients. Remarkably, global metabolomic profiling of tumor tissues identified a total of 418 distinct metabolites, out of which 133 (31.8%) were shown to differ between the ER(+) and TNBC tumors with statistical probability of p<0.05. Specific biochemical pathways affected included those reflecting general increases in energy metabolism and transmethylation in the TNBC tumors when compared to ER(+) tumors. Additionally, biochemicals associated with increased proliferation, redox balance and the recently proposed oncometabolites, sarcosine and 2-hydroxyglutarate, were also detected at higher levels in the TNBC versus ER(+) tumors. These studies demonstrate that TNBC tumors have metabolic signatures that distinguish them from ER(+) tumors and suggest that distinctive metabolic characteristics of these tumors might offer new targets for treatment.

RESUMO

OBJECTIVES: Obesity is a risk factor for many cancers and obese cancer patients have a poorer prognosis. This study aimed to evaluate the prevalence of obesity and attempts to lose weight among cancer survivors. The effects of cancer treatment and time since cancer treatment were also evaluated. METHODS: The 2007 Health Information National Trends Survey data were analysed between 2011 and 2013; respondents with (n = 966) and without (n = 6,093) a personal history of cancer were identified. Each respondent's body mass index (BMI) was calculated using self-reported height and weight measurements and categorised as normal (<25 kg/m(2)), overweight (25-29.9 kg/m(2)) or obese (≥30 kg/m(2)). RESULTS: Cancer survivors were older (mean age = 63.4 versus 44.7 years for those with no history of cancer). Overall, there were similar percentages of overweight (37.6% versus 34.1%; relative risk ratio [RRR] = 0.99; 95% confidence interval [CI]: 0.75-1.31) and obese (31.4% versus 27.5%; RRR = 1.04; 95% CI: 0.79 1.39) respondents among both cancer survivors and those without a history of cancer. Among overweight and obese participants, cancer survivors did not demonstrate increased weight loss attempts compared to those without a history of cancer (61.6% versus 66.3%; odds ratio = 0.94; 95% CI: 0.73 1.20). CONCLUSION: A high prevalence of overweight and obese cancer survivors were identified without any association with cancer treatment. However, cancer survivors did not demonstrate increased attempts to lose weight in comparison to those without a history of cancer despite awareness of their degree of body fatness. Increased efforts to promote the maintenance of a healthy weight among cancer survivors are needed.

RESUMO

BACKGROUND: Fascin, an actin bundling protein, plays a critical role in cell motility due to formation of actin rich protrusions called filopodia, important in cell migration, invasion and metastatic spread. Fascin overexpression has been associated with epithelial to mesenchymal transition and correlates with progression and unfavourable prognosis in breast carcinoma. OBJECTIVE: To evaluate fascin expression by immunohistochemistry and correlate the expression pattern with clinicopathological parameters in breast cancer in African-American (AA) women, in whom triple negative breast cancer (TNBC), an aggressive subtype, is more prevalent. METHODS: Tissue microarrays were constructed from formalin-fixed, paraffin-embedded blocks of tumour tissue from primary breast carcinomas in 202 AA women. Immunohistochemical detection of fascin was correlated with four major subtypes of breast carcinoma (luminal A, luminal B, human epidermal growth factor receptor 2 and triple negative (TN)) and other clinicopathological factors, including age, grade, tumour size, stage, regional lymph node status and survival. RESULTS: We observed a significant association between fascin expression and TN subtype, oestrogen receptor (ER) negativity, progesterone receptor (PR) negativity, Elston-Nottingham (EN) grade 3 and decreased overall survival. There was also a significant association between expression of CK 5/6, a marker of basal-like phenotype, and fascin expression. CONCLUSION: These results suggest that fascin is a marker for TN subtype having a basal-like phenotype and decreased overall survival. Fascin may represent a target for therapy in TNBC in AA women.

RESUMO

BACKGROUND: Patient Navigation (PN) originated in Harlem as an intervention to help poor women overcome access barriers to timely breast cancer treatment. Despite rapid, nationally widespread adoption of PN, empirical evidence on its effectiveness is lacking. In 2005, National Cancer Institute initiated a multicenter PN Research Program (PNRP) to measure PN effectiveness for several cancers. The George Washington Cancer Institute, a project participant, established District of Columbia (DC)-PNRP to determine PN's ability to reduce breast cancer diagnostic time (number of days from abnormal screening to definitive diagnosis). METHODS: A total of 2,601 women (1,047 navigated; 1,554 concurrent records-based nonnavigated) were examined for breast cancer from 2006 to 2010 at 9 hospitals/clinics in DC. Analyses included only women who reached complete diagnostic resolution. Differences in diagnostic time between navigation groups were tested with ANOVA models including categorical demographic and treatment variables. Log transformations normalized diagnostic time. Geometric means were estimated and compared using Tukey-Kramer P value adjustments. RESULTS: Average-geometric mean [95% confidence interval (CI)]-diagnostic time (days) was significantly shorter for navigated, 25.1 (21.7, 29.0), than nonnavigated women, 42.1 (35.8, 49.6). Subanalyses revealed significantly shorter average diagnostic time for biopsied navigated women, 26.6 (21.8, 32.5) than biopsied nonnavigated women, 57.5 (46.3, 71.5). Among nonbiopsied women, diagnostic time was shorter for navigated, 27.2 (22.8, 32.4), than nonnavigated women, 34.9 (29.2, 41.7), but not statistically significant. CONCLUSIONS: Navigated women, especially those requiring biopsy, reached their diagnostic resolution significantly faster than nonnavigated women. IMPACT: Results support previous findings of PN's positive influence on health care. PN should be a reimbursable expense to assure continuation of PN programs.

RESUMO

BACKGROUND AND AIM: Negative association has been reported between presence of Helicobacter pylori and developing gastroesophageal reflux disease (GERD) and its complications. The aim of this study was to determine whether H. pylori (HP) can be protective against GERD in an African American (AA) population. METHODS: From 2004 to 2007, we studied 2,020 cases; esophagitis (58), gastritis (1,558), both esophagitis and gastritis (363) and a normal control group (41). We collected their pathology and endoscopy unit reports. HP status was determined based on staining of gastric biopsy. RESULTS: HP data was available for 79 % (1,611) of the cases. The frequency of HP positivity in gastritis patients was 40 % (506), in esophagitis patients 4 % and in normal controls 34 % (11), while HP was positive in 34 % of the patients with both esophagitis and gastritis. After adjusting for effects of age and sex, odds ratio of HP was 0.06 (95 % CI 0.01-0.59; P value = 0.01) for the esophagitis group versus the normal group. CONCLUSIONS: Our results show H. pylori has a significant negative association with esophagitis in AAs which may point to a protective role of H. pylori in the pathogenesis of esophagitis. In addition, H. pylori may be the reason for the low GERD complications in AAs.

RESUMO

BACKGROUND: The problem of obesity has risen to epidemic levels in the United States. A subset of patients with obesity will have metabolic syndrome. We sought to examine the impact of metabolic syndrome on the risk of morbidity and mortality among a large cohort of patients who underwent hepatic resection. METHODS: Patients included in the National Surgical Quality Improvement Program (NSQIP) dataset who underwent hepatic resection between January 2005 and December 2008 were identified. Data on clinical characteristics, comorbidities, operative details, as well as postoperative complications and mortality were collected and analyzed. Patients with BMI >30 kg/m(2) who also had hypertension and diabetes were defined as having metabolic syndrome. RESULTS: A total of 3,973 patients who underwent a liver resection were identified. Overall mean body mass index was 28 kg/m(2); 31.7% patients were obese (>30 kg/m(2)). Of the patients who were obese, 256 (20%) had metabolic syndrome. Patients with metabolic syndrome were less likely to have had a major hepatectomy (≥hemi-hepatectomy, 36% vs 43%; P = .01) but had a greater mean number of red blood cell transfusions (1.6 vs 1; P = .02). The incidence of postoperative complications after hepatectomy was 23%. Patients with metabolic syndrome had a greater risk for reintubation (odds ratio [OR] 1.9; P = .02), >48 hours ventilator dependence (OR 2.0; P = .003), myocardial infarction (OR 5.5; P = .01) and superficial surgical-site infections (OR 1.7; P = .02) compared with nonmetabolic patients. Overall postoperative mortality was 3%. Metabolic syndrome was associated with an increased risk of postoperative death (OR 2.7; P = .001). CONCLUSION: The presence of metabolic syndrome was associated with a greater risk of perioperative complications. In addition, patients with metabolic syndrome had greater than a 2-fold increased risk of death after hepatic resection.

RESUMO

BACKGROUND: Fear of recurrence (FOR) is a psychological concern that has been studied extensively in cancer survivors but has not been adequately examined in African-American breast cancer survivors. PURPOSE: This exploratory study describes the extent and nature of FOR in African-American breast cancer survivors. FOR is examined in relation to socio-demographic characteristics, treatment-related characteristics, psychological distress, and quality of life (QOL). METHODS: Participants completed questionnaires assessing FOR, psychological distress, QOL, and demographic and treatment characteristics. Pearson r correlations, t tests, and ANOVAs were used to determine the association between FOR and demographic and treatment-related characteristics. Hierarchical multiple regression models were performed to investigate the degree to which FOR dimensions account for the variance in QOL and psychological distress. RESULTS: Fifty-one African-American breast cancer survivors participated in this study. The mean age of participants was 64.24 (SD = 12.3). Overall fears as well as concerns about death and health were rated as low to moderate. Role worries and womanhood worries were very low. Inverse relationships were observed between age and FOR dimensions. FOR was positively correlated with measures of psychological distress and negatively correlated with QOL. FOR significantly accounted for a portion of the variance in QOL and distress after controlling for other variables. CONCLUSIONS: This study suggests that African-American women in this sample demonstrated some degree of FOR. Results indicate that FOR among African-American breast cancer survivors decreases with age and time since diagnosis and co-occurs with psychological distress as well as diminished quality of life.

RESUMO

OBJECTIVES: The goals of this study were (i) to report the prevalence and nature of sleep disturbances, as determined by clinically significant insomnia symptoms, in a sample of African-American breast cancer survivors; (ii) to assess the extent to which intrusive thoughts about breast cancer and fear of recurrence contributes to insomnia symptoms; and (iii) to assess the extent to which insomnia symptoms contribute to fatigue. METHODS: African-American breast cancer survivors completed surveys pertaining to demographics, medical history, insomnia symptoms, and intrusive thoughts about breast cancer, fear of cancer recurrence, and fatigue. Hierarchical regression models were performed to investigate the degree to which intrusive thoughts and concerns of cancer recurrence accounted for the severity of insomnia symptoms and insomnia symptom severity's association with fatigue. RESULTS: Forty-three percent of the sample was classified as having clinically significant sleep disturbances. The most commonly identified sleep complaints among participants were sleep maintenance, dissatisfaction with sleep, difficulty falling asleep, and early morning awakenings. Intrusive thoughts about breast cancer were a significant predictor of insomnia symptoms accounting for 12% of the variance in insomnia symptom severity. After adjusting for covariates, it was found that insomnia symptom severity was independently associated with fatigue accounting for 8% of variance. CONCLUSIONS: A moderate proportion of African-American breast cancer survivors reported significant problems with sleep. Sleep disturbance was influenced by intrusive thoughts about breast cancer, and fatigue was associated with the severity of participants' insomnia symptoms. This study provides new information about sleep-related issues in African-American breast cancer survivors.

RESUMO

INTRODUCTION: Due to increased awareness of breast cancer resulting in early detection, there is a decreased incidence nationwide of late-stage breast cancer, including that which presents with skin involvement (T4b). METHODS: A retrospective analysis of a 10-month period from August 2007 to May 2008 at Howard University Hospital (HUH), Washington, DC, revealed 12 patients diagnosed with T4b breast cancer and compared to similarly staged patients in the Surveillance, Epidemiology, and End Results (SEER) database. Finally, a logistic regression for the likelihood of T4b diagnosis was performed patients in the SEER database. RESULTS: HUH patients with T4b tumors were more likely than SEER patients to present with predictors of poor clinical outcome, including high-grade histology (100% vs 59.4%, p = .04) and estrogen receptor- (75% vs 30.3%, p = .001) and progesterone receptor- negative (91.7% vs 43.9%, p = .001) status. Conversely, HUH patients were younger (57.8 y vs 66.3 y, p = .03) and had smaller tumors (11.1 cm vs 28.2 cm, p = .02) than SEER patients with similarly staged tumors. Older patients (OR, 2.36; 95% CI, 1.50-2.00; p < .001; 60-80 y), African American patients (OR, 1.63; 95% CI, 1.26-2.11; p < .001), and patients with high-grade (OR, 5.51; 95% CI, 3.88-6.52; p < .001) tumors were more likely to be diagnosed with T4b tumors, whereas patients who lived in an area with increased median household income (OR, 0.99; 95% CI, 0.99-0.99; p = .001) were less likely to be diagnosed with a T4b lesion. CONCLUSION: While much research has focused on the socioeconomic causes for the development of T4b tumors, both patient and tumor biologic conditions cannot be eliminated as causative agents.

RESUMO

HYPOTHESIS: Extended surgical resection (ESR) may improve survival in patients with early-stage primary gallbladder cancer. DESIGN: Retrospective analysis of findings in the Surveillance, Epidemiology, and End Results (SEER) database. SETTING: Academic research. PATIENTS: Individuals with potentially surgically curable gallbladder cancer (Tis, T1, or T2) who underwent a surgical procedure. MAIN OUTCOME MEASURES: Overall survival, number of lymph nodes (LNs) excised, and results of simple cholecystectomy vs ESR. RESULTS: We identified 3209 patients with early-stage gallbladder cancer (11.7% Tis, 30.1% T1, and 58.2% T2). On multivariate analysis, decreased survival was noted among patients older than 60 years (hazard ratio, 1.57; 95% confidence interval, 1.30-1.90), among patients with more advanced cancer (1.99; 1.46-2.70 for T1; 3.29; 2.45-4.43 for T2), and among patients with disease-positive LNs (1.65; 1.39-1.95 for regional; 2.58; 1.54-4.34 for distant) (P < .001 for all), while increased survival was observed among female patients (0.82; 0.70-0.96; P = .02) and among patients undergoing ESR (0.59; 0.45-0.78; P < .001). The survival advantage of ESR was seen only in patients with T2 lesions (0.49; 0.35-0.68; P < .001). Lymph node excision data were available for a subset of 2507 patients, of whom 68.2% had no LN excised, 28.2% had 1 to 4 LNs excised, and 3.6% had 5 or more LNs excised. On multivariate analysis, patients with 1 to 4 LNs excised had a survival benefit over those with no LN excised (HR, 0.55; 95% CI, 0.46-0.66; P < .001), and patients with 5 or more LNs excised had a survival benefit over patients with 1 to 4 LNs removed (0.63; 0.40-0.96; P = .03). Lymph node excision improved survival in patients with T2 lesions (0.42; 0.33-0.53; P < .001 for patients with 1-4 LNs excised). CONCLUSION: Extended surgical resection, LN excision, or both may improve survival in certain patients with incidentally discovered gallbladder cancer.

RESUMO

BACKGROUND: The clinical trials mechanism of standardized treatment and follow-up for cancer patients with similar stages and patterns of disease is the most powerful approach available for evaluating the efficacy of novel therapies, and clinical trial participation should protect against delivery of care variations associated with racial/ethnic identity and/or socioeconomic status. Unfortunately, disparities in clinical trial accrual persist, with African Americans (AA) and Hispanic/Latino Americans (HA) underrepresented in most studies. STUDY DESIGN: We evaluated the accrual patterns for 10 clinical trials conducted by the American College of Surgeons Oncology Group (ACOSOG) 1999-2009, and analyzed results by race/ethnicity as well as by study design. RESULTS: Eight of 10 protocols were successful in recruiting AA and/or HA participants; three of four randomized trials were successful. Features that were present among all of the successfully recruiting protocols were: (1) studies designed to recruit patients with regional or advanced-stage disease (2 of 2 protocols); and (2) studies that involved some investigational systemic therapy (3 of 3 protocols). DISCUSSION: AA and HA cancer patients can be successfully accrued onto randomized clinical trials, but study design affects recruitment patterns. Increased socioeconomic disadvantages observed within minority-ethnicity communities results in barriers to screening and more advanced cancer stage distribution. Improving cancer early detection is critical in the effort to eliminate outcome disparities but existing differences in disease burden results in diminished eligibility for early-stage cancer clinical trials among minority-ethnicity patients.

RESUMO

BACKGROUND: Appendectomy remains one of the most common emergency surgical procedures encountered throughout the United States. With improvements in diagnostic techniques, the efficiency of diagnosis has increased over the years. However, the entity of negative appendectomies still poses a dilemma because these are associated with unnecessary risks and costs to both patients and institutions. This study was conducted to show current statistics and trends in negative appendectomy rates in the United States. METHODS: A retrospective analysis was conducted using data from the National Inpatient Sample from 1998 to 2007. Adult patients (>18 y) having undergone appendectomies were identified by the appropriate International Classification of Diseases 9th revision codes. Patients with incidental appendectomy and those with appendiceal pathologies, also identified by relevant International Classification of Diseases 9th revision codes, were excluded. The remaining patients represent those who underwent an appendectomy without appendiceal disease. The patients then were stratified according to sex, women were classified further into younger (18-45 y) and older (>45 y) based on child-bearing age. The primary diagnoses subsequently were categorized by sex to identify the most common conditions mistaken for appendiceal disease in the 2 groups. RESULTS: Between 1998 and 2007, there were 475,651 cases of appendectomy that were isolated. Of these, 56,252 were negative appendectomies (11.83%). There was a consistent decrease in the negative appendectomy rates from 14.7% in 1998 to 8.47% in 2007. Women accounted for 71.6% of cases of negative appendectomy, and men accounted for 28.4%. The mortality rate was 1.07%, men were associated with a higher rate of mortality (1.93% vs .74%; P < .001). Ovarian cyst was the most common diagnosis mistaken for appendicitis in younger women, whereas malignant disease of the ovary was the most common condition mistaken for appendiceal disease in women ages 45 and older. The most common misdiagnosis in men was diverticulitis of the colon. CONCLUSIONS: There has been a consistent decline in the rates of negative appendectomy. This trend may be attributed to better diagnostics. Gynecologic conditions involving the ovary are the most common to be misdiagnosed as appendiceal disease in women.

RESUMO

When initiated by the devastating diagnosis of cancer, post ablative breast restoration has at its core the goal of restoring anatomic normalcy. The concepts of body image, wholeness, and overall well-being have been introduced to explain the paramount psychological influence the breast has on both individuals and society as a whole. Hence, a growing subspecialty has been established to recreate or simulate the lost breast. At least one third of breast cancer victims consider breast reconstruction. Breast reconstruction post mastectomy may be offered at the time of mastectomy or delayed post mastectomy after adjuvant therapy. This may be utilizing autologous tissues or implants and each has risks and benefits, especially when considering adjuvant therapy. In addition, there has been a move away from a traditional mastectomy to less invasive, but still curative procedures, such as skin-sparing and nipple-sparing mastectomy. These procedures provide the breast envelope to facilitate reconstruction. This paper reviews the primary issues in breast reconstruction, as well as their psychologic, oncologic, and social impact.

RESUMO

BACKGROUND: Accidental traumatic injury is the number 1 cause of morbidity and mortality in the pediatric population. In this study, we aim to prove that certain pediatric patients can be treated with good outcomes at an adult level 1 trauma center. METHODS: Retrospective analysis using the Howard University Hospital trauma registry identified 71 patients treated at Howard University Hospital between the ages of 1 and 17 years old. Specific variables were identified and collected for each patient. RESULTS: The majority of pediatric traumas treated at Howard University Hospital between June 2004 and May 2005 had high survival rates (93%). The patients who did not survive (7%) included 3 patients who were dead on arrival and 2 who died shortly after arrival to the hospital. CONCLUSIONS: Certain pediatric populations who present with minor and/or isolated injuries can be treated in an adult level 1 trauma center with similar outcomes to treatment in a pediatric level 1 trauma center.
