The shortage of pathologists in the United States has been a topic of discussion for the past 2 decades. At the 2014 Association of Pathology Chairs (APC)/Program Directors Section (PRODS) meeting, a Pipeline Subcommittee (PSC) of the APC Advocacy Committee was formed with the charge of investigating ways to increase the number of highly qualified United States Medical Graduates entering into pathology. Several online surveys were developed to identify the strengths, weaknesses, opportunities, and threats to recruitment into pathology.

The pathologist workforce in the United States is a topic of interest to the health-care community as a whole and to institutions responsible for the training of new pathologists in particular. Although a pathologist shortage has been projected, there has been a pervasive belief by medical students and their advisors that there are "no jobs in pathology." In 2013 and again in 2017, the Program Directors Section of the Association of Pathology Chairs conducted surveys asking pathology residency directors to report the employment status of each of their residents graduating in the previous 5 years.

Autopsy has been a foundation of pathology training for many years, but hospital autopsy rates are notoriously low. At the 2014 meeting of the Association of Pathology Chairs, some pathologists suggested removing autopsy from the training curriculum of pathology residents to provide additional months for training in newer disciplines, such as molecular genetics and informatics. At the same time, the American Board of Pathology received complaints that newly hired pathologists recently certified in anatomic pathology are unable to perform an autopsy when called upon to do so.

The required medical knowledge and skill set for the pathologist of 2020 are different than in 2005. Pathology residency training curriculum must accordingly change to fulfill the needs of these ever-changing requirements. In order to make rational curricular adjustments, it is important for us to know the current trajectory of resident training in pathology-where we have been, what our actual current training curriculum is now-to understand how that might change in anticipation of meeting the needs of a changing patient and provider population and to fit within the evolving future biomedical and socioeconomic health-care setting.

Patients with succinate dehydrogenase (SDH)-deficient gastrointestinal stromal tumor (GIST) have few therapeutic options. Despite lack of KIT or platelet-derived growth factor receptor A (PDGFRA) driver mutations, SDH-deficient GISTs display strong expression of KIT by immunohistochemistry and these patients are often treated with tyrosine kinase inhibitors, including imatinib as a first-line therapy. Using a targeted next-generation sequencing panel of mutation hotspots of 50-clinically relevant genes, we investigated (1) concurrence of somatic/actionable mutations and (2) tumor molecular evolution by comparing 2 resection specimens 1.

A shortage of physicians in the United States has been long projected. Because of predictions of retirement among the aging pathology workforce, there is an anticipated shortage of pathologist as well. To address the pathology workforce shortage among pathologists, the Association of Pathology Chairs assembled a subcommittee of the Association of Pathology Chairs Advocacy Committee to explore ways to identify the strengths, weaknesses, opportunities, and threats to the pathology workforce.

The majority of pathology residency training programs in the United States are considered to be small training programs. Small training programs, regardless of specialty, encounter unique challenges that have been documented in the literature. With the implementation of the Next Accreditation System (NAS), and other Accreditation Council for Graduate Medical Education (ACGME) Common Program Requirements, adequate personnel and other resources are necessary.

Background: Diagnosis of basal-like breast cancer (BLBC) remains a bottleneck to conducting effective clinical trials for this aggressive subtype. We postulated that elevated expression of Forkhead Box transcription factor C1 (FOXC1) is a simple and accurate diagnostic biomarker for BLBC.

Methods: Accuracy of FOXC1 expression in identifying BLBC was compared with the PAM50 gene expression panel in gene expression microarray (GEM) (n = 1992) and quantitative real-time polymerase chain reaction (qRT-PCR) (n = 349) datasets.

Context: The Liaison Committee on Medical Education began an initiative to change medical education across the United States in the early 2000s. With the explosion in medical science knowledge, the need arose to teach selected fundamental information both in a contextual and in an active learning manner.

Objective: To identify ways to address gaps in training and knowledge that became apparent following implementation of learner-centered teaching methods, with devotion of more time to Internet-based learning and less emphasis on face-to-face lecture time.

Context: In the late 1990s, the Accreditation Council for Graduate Medical Education developed the Outcomes Project and the 6 general competencies with the intent to improve the outcome of graduate medical education in the United States. The competencies were used as the basis for developing learning goals and objectives and tools to evaluate residents' performance. By the mid-2000s the stakeholders in resident education and the general public felt that the Outcomes Project had fallen short of expectations.

Background: Glutathione S-transferase Pi (GSTPi) expression is one of the factors, which is known to be associated with development of resistance to chemotherapeutics in cancer patients, including those with breast cancer. Yet, its expression has been reported to be undetectable in cancer cells in high percent of patients with primary breast cancer. However, GSTPi expression in stromal cells in breast tumour microenvironment, namely cancer-associated fibroblast (CAF), which is recognised to have major roles in cancer progression, remains poorly reported.

Background: The concurrent determination of methylation status of E-cadherin gene and E-cadherin protein expression remains scant in metastatic prostate cancer cells in bone, the most prevalent site for metastatic growth. Therefore, the study was undertaken to ascertain the methylation status of E-cadherin gene, a most frequent and known epigenetic mechanism of its regulation, and the protein expression in prostate tissue biopsy specimen.

Methods: The methylation of E-cadherin gene was determined by methylation specific-PCR and the protein expression by immunohistochemical method in the consecutive sections of each prostate tissue biopsy specimen.

The expression of the catalytic subunit of telomerase protein (human telomerase reverse transcriptase [hTERT]), which is associated with telomerase activity, was evaluated as a potential marker of the high-grade premalignant cervical intraepithelial neoplasia (CIN 2/3) lesions. For comparison, cases of normal cervical squamous mucosa, low-grade CIN1 lesion, and cervical squamous cell carcinoma were included. The hTERT expression was also compared with Ki-67 and topoisomerase II-alpha (TPII-alpha) to determine the proliferative activity of the hTERT-positive dysplastic cells by a quantitative immunohistochemical staining method and was classified as follows: negative, 5% or less; moderate, 6% to 50%; or high, greater than 50% of the positive cells.

A survey of pathology training programs about current operations and attitudes revealed that the autopsy is underused in medical student and pathology resident teaching, is inadequately reported, often does not have a dedicated faculty, is not championed by pathologists or clinicians, is not valued as a performance measure, and is barely used as a resource for medical research. The autopsy can be reestablished as a teaching tool and performance measure, but this will require that the autopsy be recognized as a credible and valuable medical procedure. The autopsy must then be funded; and new sources of both volume and funding, such as incorporating autopsies into payment schedules, into clinical trials, and in pay-for-performance initiatives, must be solicited.

Context: Success in the practice of pathology demands proficiency in management, but management training for pathology residents is generally inadequate, with little agreement on an appropriate curriculum or competency assessment. Most residency training programs do not have faculty members who are interested and have expertise in management and who are dedicated to and have time available for teaching.

Objective: To develop a didactic management training program for the residents from 6 separate pathology residency programs in Southern California, with a comprehensive curriculum taught by experts in each area without undue burden on any single training program.
