Getting a reliable diagnosis of melanoma can be a significant challenge for pathologists. The diagnosis relies on a pathologist ’s visual assessment of biopsy material on microscopic slides, which can often be subjective. Now, UCLA researchers have found that obtaining a second opinion from pathologists who are board certified or have fellowship training in dermatopathology can help improve the accuracy and reliability of diagnosing melanoma, one of the deadliest and most aggressive forms of skin cancer.“A diagnosis is the building block on which all other medical treatment is based,” said Dr. Joann ...

Pancreatic cancer is a rare cancer that carries a poor 5 year survival rate of approximately 5% [1]. Approximately 5% to 10% of individuals with pancreatic cancer report having a closely related family member also being diagnosed with pancreatic cancer [2]. Several known genetic syndromes, such as hereditary breast-ovarian cancer syndrome (HBOC) [3], Lynch syndrome [4], familial adenomatous polyposis [5], familial atypical multiple mole melanoma syndrome [6], hereditary pancreatitis [7], Peutz-Jeghers syndrome [8], and Li-Fraumeni syndrome [9] are associated with increased risk of pancreatic cancer.

FRIDAY, Oct. 11, 2019 -- Melanoma is the most lethal type of skin cancer, and a new study finds that the diagnosis of a suspect lesion gains accuracy when a specialist pathologist is brought on board. Many patients with melanoma are first diagnosed...

Tumor stroma resembles a fibrotic microenvironment, being characterized by the presence of myofibroblast-like cancer-associated fibroblasts (CAFs). In wild-type mice injected with melanoma cells, we show that the stem cell transcription factor Sox2 is expressed by tumor cells and induced in CAFs derived from synthetic fibroblasts. These fibroblasts were labeled postnatally with green fluorescent protein using mice expressing a tamoxifen-dependent Cre recombinase under the control of a fibroblast-specific promoter/enhancer.

Computational pathology-based cell classification algorithms are revolutionizing the study of the tumor microenvironment and can provide novel predictive/prognosis biomarkers crucial for the delivery of precision oncology. Current algorithms used on hematoxylin and eosin slides are based on individual cell nuclei morphology with limited local context features. Here, we propose a novel multi-resolution hierarchical framework (SuperCRF) inspired by the way pathologists perceive regional tissue architecture to improve cell classification and demonstrate its clinical applications. We develop SuperCRF by training a state-of-art...

Abstract BACKGROUND/OBJECTIVES: Melanoma may develop de novo or naevus associated (NAM). The exact prevalence and features of NAM are not fully elucidated. METHODS: A 15-year cross-sectional retrospective study was performed of all melanoma cases diagnosed and treated at the skin cancer centre of the University of Naples Federico II from September 2003 to August 2018. Data collected included patient's age, gender, melanoma anatomic site, Breslow thickness, and histolopathology including melanoma-associated lesion characteristics. RESULTS: A total of 1986 melanomas were included in the stud...

Abstract The culture supernatant from macrophages overexpressing TRIM59 has a cytotoxic effect on melanoma, but the mechanism remains unclear. To investigate whether deletion of TRIM59 in macrophages affects the metastatic potential of melanoma cells, we polarized control and TRIM59-deficient bone marrow-derived macrophages to the M2 phenotype and collected the respective conditioned media (CM). Exposure to CM from TRIM59-/--M2 cultures significantly promoted migration and invasion by B16-F0 and B16-F10 cells. Cytokine profiling indicated a ~15-fold increase in TNF-α production in CM from TRIM59-/--M2 cultur...

Abstract The deep and durable antitumor effects of antibody-based immunotherapies such as immune checkpoint inhibitors (ICIs) have revolutionized oncology and transformed the therapeutic landscape for many cancers. Several anti-programmed death receptor 1 and anti-programmed death receptor ligand 1 antibodies have been approved for use in advanced solid tumors, including melanoma, non-small cell lung cancer (NSCLC), bladder cancer, and other cancers. ICIs are under development across many tumor types and preliminary results are compelling. However, ICIs have been associated with severe immune-related adverse event...
