Association between medical home enrollment and health care utilization and costs among breast cancer patients in a state Medicaid program.
The objective of this study was to examine health care utilization and expenditures as a function of patient-centered medical home (PCMH) enrollment among breast cancer patients in North Carolina’s Medicaid program. It found that PCMH enrollment was significantly associated with greater outpatient service use, but there was no difference in the probability of inpatient hospitalizations or ED visits.

Population-based study of the effect of gene expression profiling on adjuvant chemotherapy use in breast cancer patients under the age of 65 years.
The authors evaluated the relation between gene expression profiling (GEP) testing and the use of adjuvant chemotherapy by women treated in a general oncology practice. They found that adjuvant chemotherapy use after GEP testing is generally consistent with the recommended test interpretation for women with a high or low predicted risk of recurrence. Chemotherapy use in the intermediate-risk group increased with Recurrence Score values, and evidence from ongoing randomized trials may help to clarify whether this finding reflects optimal interpretation of GEP test results.

Association between use of the 21-gene recurrence score assay and receipt of chemotherapy among Medicare beneficiaries with early-stage breast cancer, 2005-2009.
The researchers examined whether adoption of the 21-Gene Recurrence Score (RS) assay in a nationally representative sample of patients with early-stage breast cancer was associated with use of chemotherapy. They found that the impact of the adoption of the RS assay on receipt of chemotherapy was strongly population dependent and was associated with relatively lower chemotherapy use in groups with high-risk disease and relatively higher chemotherapy use in patients with low-risk disease.

A non-randomized controlled stepped wedge trial to evaluate the effectiveness of a multi-level mammography intervention in improving appointment adherence in underserved women.
This study evaluated a theoretically based, systematically designed implementation strategy to support adoption and implementation of a patient navigation-based intervention, called Peace of Mind Program (PMP), aimed at improving breast cancer screening among underserved women.. Any potential confounding or bias will be controlled in the analysis. Outcomes such as appointment adherence, patient referral to diagnostics, time to diagnostic referral, patient referral to treatment, time to treatment referral, and budget impact of the intervention will be assessed.

Has racial difference in cause-specific death improved in older patients with late-stage breast cancer?
The researchers evaluated factors associated with overall, breast cancer-specific and other-cause mortalities using contemporary population data. They concluded that breast cancer-specific mortality among older women modestly improved from 2002 to 2009 across all races, but not other-cause mortality. Racial disparity in mortality persisted, but did not widen in this period.

Racial and ethnic disparity in symptomatic breast cancer awareness despite a recent screen: the role of tumor biology and mammography facility characteristics.
In a racially and ethnically diverse sample of recently diagnosed urban patients with breast cancer, the researchers examined associations of patient, tumor biology, and mammography facility characteristics on the probability of symptomatic discovery of their breast cancer despite a recent prior screening mammogram. They concluded that facility resources and tumor aggressiveness explain much of the racial/ethnic disparity in symptomatic breast cancer among recently screened patients.

Comparative effectiveness of chemotherapy regimens in prolonging survival for two large population-based cohorts of elderly adults with breast and colon cancer in 1992-2009.
The purpose of this study was to compare the effectiveness of chemotherapy in prolonging survival according to age in breast and colon cancer. It found that the effectiveness of chemotherapy decreased with age in participants with breast cancer, in whom chemotherapy appears to be effective until age 79 except for the doxorubicin-cyclophosphamide combination, which was effective in participants aged 80 to 84.

Non-normal screening mammography results, lumpectomies, and breast cancer reported by California women, 2001-2009.
This study report trends in self-reported non-normal screening mammography results, lumpectomies, and breast cancer in California women. Between 2001 and 2009, the percent of California women who reported having been diagnosed with breast cancer was relatively stable. For each of the three age groups studied, the percentage of non-normal mammography results increased and the percentages of lumpectomies decreased.

Initial trends in the use of the 21-gene recurrence score assay for patients with breast cancer in the Medicare population, 2005-2009.
The researchers examined trends in the use of the 21-gene recurrence score (RS) assay in routine clinical practice in a nationally representative sample of women with breast cancer. They found that the RS assay was adopted quickly in clinical practice after the Medicare coverage decision in 2006, and use appears to be consistent with guidelines and equitable across geographic and racial groups.

Risk assessment, genetic counseling, and genetic testing for BRCA-related cancer in women.
L.M. is a 37-year-old nonsmoking woman who is not taking any medications and has no significant past medical problems. As breast cancer runs in her family, she is interested in genetic testing for breast cancer. This case study poses three multiple choice questions together with the U.S. Preventive Services Task Force recommendations and related background information.

Increased risk of surgical site infection among breast-conserving surgery re-excisions.
The aim of this study was to determine the risk of surgical site infection (SSI) after primary breast-conserving surgery (BCS) versus re-excision among women with carcinoma in situ or invasive breast cancer. It found that the risk of SSI after re-excision remained significantly higher after accounting for multiple procedures within a woman.

Association between persistence with mammography screening and stage at diagnosis among elderly women diagnosed with breast cancer.
The objective of this study is to determine the association between persistence with mammography screening and stage at breast cancer (BC) diagnosis among elderly women. It found that, as compared to women who were not persistent with mammography screening, women who were persistent with mammography screening were significantly more likely to be diagnosed at earlier stages of BC.

Validation of disability status, a claims-based measure of functional status for cancer treatment and outcomes studies.
The researchers implemented and validated a disability status (DS) measure in 4 cohorts of cancer patients. They found that the DS measure is a significant independent predictor of cancer-directed treatment, but unobserved factors continue to play a role in determining treatments.

Racial disparities in healthy behaviors and cancer screening among breast cancer survivors and women without cancer: National Health Interview Survey 2005.
This study aimed to compare healthy behaviors and cancer screening practices among breast cancer survivors and respondents without cancer separately in Caucasian, African American, and Hispanic women. It found that most differences were suggestive and do not differ by race.

Risk assessment, genetic counseling, and genetic testing for BRCA-related cancer in women: a systematic review to update the U.S. Preventive Services Task Force recommendation.
This systematic review was done in support of the U.S. Preventive Services Task Force (USPSTF) updated recommendation on the benefit and harms of risk assessment, genetic testing, and genetic counseling for BRCA-related cancer in women. A systematic review was done on literature from 2004 to July 30, 2013 from MEDLINE, PsycINFO, the Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Health Technology Assessment, Scopus, and reference lists. Data on the participants, study design, analysis, follow-up, and results was extracted and a second investigator confirmed key data. The studies were rated on study quality and applicability. The analysis found women with high-risk for breast cancer had decreased risk of breast cancer by 85% to 100% by having a mastectomy, and risk of mortality by 81% to 100% compared to women without surgery. There was also a lower risk of breast and ovarian cancer after having salpingo-oopherectomy surgery.
