A Decade of Change: An Institutional Experience with Breast Surgery in 1995 and 2005

Introduction: With the adoption of routine screening mammography, breast cancers are being diagnosed at earlier stages, with DCIS now accouting for 22.5% of all newly diagnosed breast cancers. This has been attributed to both increased breast cancer awareness and improvements in breast imaging techniques. How have these changes, including the increased use of image-guided sampling techniques, influenced the clinical practice of breast surgery?Methods: The institutional pathology database was queried for all breast surgeries, including breast reconstruction, performed in 1995 and 2005. Cosmetic procedures were excluded. The results were analysed utilizing the Chi-square test.Results: Surgical indications changed during 10-year study period, with an increase in preoperatively diagnosed cancers undergoing definitive surgical management. ADH, and to a lesser extent, ALH, became indications for surgical excision. Fewer surgical biopsies were performed for indeterminate abnormalities on breast imaging, due to the introduction of stereotactic large core biopsy. While the rate of benign breast biopsies remained constant, there was a higher percentage of precancerous and DCIS cases in 2005. The overall rate of mastectomy decreased from 36.8% in 1995 to 14.5% in 2005. With the increase in sentinel node procedures, the rate of ALND dropped from 18.3% to 13.7%. Accompanying the increased recognition of early-stage cancers, the rate of positive ALND also decreased, from 43.3% to 25.0%.Conclusions: While the rate of benign breast biopsies has remained constant over a recent 10-year period, fewer diagnostic surgical image-guided biopsies were performed in 2005. A greater percentage of patients with breast cancer or preinvasive disease have these diagnoses determined before surgery. More preinvasive and Stage 0 cancers are undergoing surgical management. Earlier stage invasive cancers are being detected, reflected by the lower incidence of axillary nodal metastases

Roadmap for Creating an Accelerated Three-Year Medical Education Program

Medical education is undergoing significant transformation. Many medical schools are moving away from the concept of seat time to competency-based education and introducing flexibility in the curriculum that allows individualization. In response to rising student debt and the anticipated physician shortage, 35% of US medical schools are considering the development of accelerated pathways. The roadmap described in this paper is grounded in the experiences of the Consortium of Accelerated Medical Pathway Programs (CAMPP) members in the development, implementation, and evaluation of one type of accelerated pathway: the three-year MD program. Strategies include developing a mission that guides curricular development – meeting regulatory requirements, attaining institutional buy-in and resources necessary to support the programs, including student assessment and mentoring – and program evaluation. Accelerated programs offer opportunities to innovate and integrate a mission benefitting students and the public

Atypia on Breast Core Needle Biopsies: Reproducibility and Significance

Abstract. This study analyzes the interobserver variability in interpreting atypia on breast core needle biopsies and in each category of atypia calculates the upgrade risk of carcinoma in the subsequent surgical excision. We identified 51 cases of atypia on breast core needle biopsies performed at our institution from January 2003 to August 2006. The atypia was classified into 4 categories: atypical ductal hyperplasia (ADH), atypical lobular hyperplasia (ALH), flat epithelial atypia (FEA), and atypia of undetermined significance (AUS). After a tutorial session, these cases were independently reviewed by four pathologists, whose overall multi-rater kappa value for agreement on different categories of atypia was 0.79 (95% CI, 0.69-0.89), which is within the substantial agreement range. The upgrade risk in each category of atypia was as follows: ADH 20% (p = 0.04); ALH 10% (p = 0.6); FEA 16.6% (p = 0.23), and AUS 100% (p = 0.96). Based on our findings, we conclude that follow-up excision should be performed after a diagnosis of ADH. The upgrade risk did not reach statistical significance in ALH or FEA. Although follow-up excision cannot be strongly recommended in ALH and FEA, it should be considered since the upgrade risk is not negligible. Strict adherence to the diagnostic criteria and tutorial sessions can help pathologists to achieve substantial agreement in interpreting atypia on breast core needle biopsies

Can p40 (Polyclonal) Replace p63 (Clone 4A4) in the Cytologic Diagnosis of Pulmonary Non-Small Cell Carcinoma?

OBJECTIVES: Differentiating squamous cell carcinoma from adenocarcinoma (ACA) in cytology specimens can be challenging. Recent literature showed p40 had higher specificity than p63 for this purpose. METHODS: We identified 190 cytology cases with p40 (polyclonal) and p63 (monoclonal clone 4A4) immunohistochemistry, including specimens from fine-needle aspirations (FNAs) and effusions. RESULTS: ACAs of lung origin stained for p40 and p63 in 21% and 20% of cases, respectively, regardless of specimen site. Among lung FNAs of primary pulmonary ACAs (n = 42), 14% were positive for p40 and 24% were positive for p63. Of the 20 pulmonary ACAs in effusions, more cases showed p40 positivity (40%) compared with FNAs, whereas p63 were positive in 15%. Among metastatic ACAs from other sites (n = 14), more cases were positive for p40 than p63. CONCLUSIONS: Polyclonal p40 yields a level of false positivity in ACAs similar to p63, which is highest in effusions and is not limited to lung origin

Low-grade squamous intraepithelial lesion, cannot exclude high-grade: TBS says Don\u27t Use It! should I really stop it?

BACKGROUND: The Bethesda System uses a two-tiered approach in the diagnosis of cervical squamous intraepithelial lesions (SILs). Occasionally, Papanicolaou (Pap) tests with evident low-grade SIL (LSIL) also have some features suggestive but not diagnostic of high-grade SIL (HSIL). This study reviews our experience with Low-grade Squamous Intraepithelial Lesion, Cannot Exclude High-grade (LSIL-H) and discusses the best approach to report such Paps if the LSIL-H interpretation is abandoned. METHODS: Abnormal Paps were identified between January and December 2014 that had surgical follow-up within 6 months. Their biopsy outcomes were compared. Statistical analysis was performed using Pearson\u27s Chi-square and McNemar tests in SPSS software version 23. Statistical significance was defined as RESULTS: There were a total of 1049 abnormal Paps with follow-up. High-grade dysplasia/carcinoma (HGD+) was found in 8% of LSIL, 30% of LSIL-H, 52% of atypical squamous cells (ASCs), cannot rule out HSIL (ASC-H), and 77% of HSIL Paps. The detection rate of HGD+ for LSIL-H was between that of LSIL (Pearson\u27s Chi-square test, CONCLUSIONS: LSIL-H category detects more HGD+ than LSIL, and fewer than ASC-H and HSIL. If LSIL-H is eliminated, Paps with this finding are best reported as ASC-H to ensure that women with potential HGD+ undergo colposcopy in a timely manner. Reporting LSIL-H as LSIL may delay colposcopy since management of LSIL Paps depends on multiple factors (age, HPV status, etc.)

Accelerated 3-Year MD Pathway Programs: Graduates Perspectives on Education Quality, the Learning Environment, Residency Readiness, Debt, Burnout, and Career Plans.

PURPOSE: To compare perception of accelerated and traditional medical students, with respect to satisfaction with education quality, and the learning environment, residency readiness, burnout, debt, and career plans. METHOD: Customized 2017 and 2018 Medical School Graduation Questionnaires (GQs) were analyzed using independent samples t tests for means and chi-square tests for percentages, comparing responses of accelerated MD program graduates (accelerated pathway [AP] students) from 9 schools with those of non-AP graduates from the same 9 schools and non-AP graduates from all surveyed schools. RESULTS: GQ completion rates for the 90 AP students, 2,573 non-AP students from AP schools, and 38,116 non-AP students from all schools in 2017 and 2018 were 74.4%, 82.3%, and 83.3%, respectively. AP students were as satisfied with the quality of their education and felt as prepared for residency as non-AP students. AP students reported a more positive learning climate than non-AP students from AP schools and from all schools as measured by the student-faculty interaction (15.9 vs 14.4 and 14.3, respectively; P < .001 for both pairwise comparisons) and emotional climate (10.7 vs 9.6 and 9.6, respectively; P = .004 and .003, respectively) scales. AP students had less debt than non-AP students (P < .001), and more planned to care for underserved populations and practice family medicine than non-AP students from AP schools (55.7% vs 33.9% and 37.7% vs 9.4%; P = .002 and < .001, respectively). Family expectations were a more common influence on career plans for AP students than for non-AP students from AP schools and from all schools (26.2% vs 11.3% and 11.7%, respectively; P < .001 for both pairwise comparisons). CONCLUSIONS: These findings support accelerated programs as a potentially important intervention to address workforce shortages and rising student debt without negative impacts on student perception of burnout, education quality, or residency preparedness
