AbstractHistologic grading has been a simple and inexpensive method to assess tumor behavior and prognosis of invasive breast cancer grading, thereby identifying patients at risk for adverse outcomes, who may be eligible for (neo)adjuvant therapies. Histologic grading needs to be performed accurately, on properly fixed specimens, and by adequately trained dedicated pathologists that take the time to diligently follow the protocol methodology. In this paper, we review the history of histologic grading, describe the basics of grading, review prognostic value and reproducibility issues, compare performance of grading to gene expression profiles, and discuss how to move forward to improve reproducibility of grading by training, feedback and artificial intelligence algorithms, and special stains to better recognize mitoses. We conclude that histologic grading, when adequately carried out, remains to be of important prognostic value in breast cancer patients.

One of the primary objectives of the Oncology Pathology Working Group (OPWG), a joint initiative of the Veterinary Cancer Society and the American College of Veterinary Pathologists, is for oncologists and pathologists to collaboratively generate consensus documents to standardize aspects and provide guidelines for oncologic pathology. Consensus is established through review of relevant peer-reviewed literature relative to a subgroup’s particular focus. In this article, the authors provide a critical review of the current literature for grading of canine cutaneous mast cell tumors, suggest guidelines for reporting, and provide recommendations for its clinical interpretation. The article mainly focuses on histologic grading, but relevant information on mitotic count and cytological grading are also discussed. This document represents the opinions of the working group and the authors but does not constitute a formal endorsement by the American College of Veterinary Pathologists or the Veterinary Cancer Society.

Aims: To investigate the efficacy and safety of minimally invasive bronchoscopic interventions for patients with tracheobronchial mucoepidermoid carcinoma (MEC). Methods: Patients with tracheobronchial MEC were included in this retrospective study, and the clinical features, histologic grading, treatments, and cumulative survival rates were calculated. Patients were categorized into child (n = 16) and adult (n = 19) group according to their ages. Histologic grading, treatments, and survival status were compared between the two groups. Results: In pathology, high-grade MEC counts for 6.77% and 42.10% in the child and adult group, respectively. As tumor growth pattern was concerned, 93.33% and 21.05% tumors in the child and adult group present intratracheal type. Multiple bronchoscopic interventions were conducted, including rigid bronchoscopy, argon plasma coagulation (APC), dioxide carbon cryotherapy, and electric loop. Tumors could be removed by multiple bronchoscopic interventions. Bronchoscopy-associated complications were rare, including an oral mucosa injury and a glottis edema. In the child group, one patient underwent left upper lung lobectomy. In the adult group, lobectomy and/or chemotherapy and/or radiotherapy were conducted in seven patients. The 5-year survival rate was 100% and 68.90% in the child and the adult group, respectively. Conclusions: Almost all children have low-grade and intratracheal MEC; 2/5 adults have invasive high-grade MEC. Multiple bronchoscopic interventions are effective in erasing low-grade intratracheal MEC without severe complications. For high-grade invasive MEC, aggressive and comprehensive therapy should be considered.
