The Effect of the 2009 USPSTF breast cancer screening recommendations on breast cancer in Michigan: A longitudinal study

In 2009, the revised United States Preventive Services Task Force (USPSTF) guidelines recommended against routine screening mammography for women age 40â 49 years and against teaching selfâ breast examinations (SBE). The aim of this study was to analyze whether breast cancer method of presentation changed following the 2009 USPSTF screening recommendations in a large Michigan cohort. Data were collected on women with newly diagnosed stage 0â III breast cancer participating in the Michigan Breast Oncology Quality Initiative (MiBOQI) registry at 25 statewide institutions from 2006 to 2015. Data included method of detection, cancer stage, treatment type, and patient demographics. In all, 30 008 women with breast cancer detected via mammogram or palpation with an average age of 60.1 years were included. 38% of invasive cancers were identified by palpation. Presentation with palpable findings decreased slightly over time, from 34.6% in 2006 to 28.9% in 2015 (P < .001). Over the 9â year period, there was no statistically significant change in rate of palpationâ detected tumors for women age <50 years or â ¥50 years (P = .27, .30, respectively). Younger women were more likely to present with palpable tumors compared to older women in a statewide registry. This rate did not increase following publication of the 2009 USPSTF breast cancer screening recommendations.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/146414/1/tbj13034.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/146414/2/tbj13034_am.pd

Pseudoangiomatous Stromal Hyperplasia on Core Needle Biopsy Does Not Require Surgical Excision

Pseudoangiomatous stromal hyperplasia (PASH) is an uncommon, benign localized fibrotic lesion. Historically, PASH has been difficult to differentiate from angiosarcoma. This difficulty has led to recommendations of surgical excision. We sought to identify the incidence of upgraded pathology to atypia or malignancy on surgical excisional biopsy after identification of PASH on core needle biopsy (CNB). A 5-year retrospective review at a single institution was conducted including all cases of PASH confirmed on CNB. The data set was divided into patients who underwent excisional biopsy and those followed only by imaging. Primary end points included the incidence of subsequent malignancy or high-risk pathology on histologic analysis or the presentation of suspicious imaging. Thirty-seven patients were reviewed, 19 (51.4%) underwent surgical excision and 18 (48.6%) were followed with imaging alone. A palpable mass was noted in 36.8 per cent of patients in the excisional group versus 5.6 per cent in the imaging group ( P = 0.02). The median follow-up for the excisional and imaging groups were 43 and 35 months, respectively ( P = 0.85). The 95 per cent confidence interval for the presence of malignancy was 0 to 9.4 per cent. Although further characterization of PASH is needed, our data support using CNB with follow-up imaging as a safe alternative to excisional biopsy in the absence of symptoms or other clinical factors. However, further research in this area is needed. </jats:p
