Endometrial endometrioid carcinoma, G1, is more aggressive in the elderly than in the young.

Histopathology 2021 May 13. Epub 2021 May 13.

Department of Anatomic Pathology, Graduate School of Medical Sciences, Kyushu University, Fukuoka, Japan.

Aims: The aim of this study was to characterize endometrioid carcinoma, G1, in the elderly, using clinicopathological features and immunohistochemical features of surrogate markers of molecular subtypes.

Methods And Results: We retrospectively analyzed tumour samples from 268 patients with endometrioid carcinoma, G1 (<40 years: n=24, 40-59 years: n=169, ≥60 years: n=75), for whom long-term clinical follow-up data were available.

Cancer Res 2021 May 11. Epub 2021 May 11.

Department of Pathology, University of Hong Kong

Lipid accumulation exacerbates tumor development, as it fuels the proliferative growth of cancer cells. The role of medium-chain acyl-CoA dehydrogenase (ACADM), an enzyme that catalyses the first step of mitochondrial fatty acid oxidation, in tumor biology remains elusive. Therefore, investigating its mode of dysregulation can shed light on metabolic dependencies in cancer development. Read More

PD1/PD-L1 Expressions in Plasmablastic Lymphoma with Clinicopathological Correlation.

Ann Clin Lab Sci 2021 Mar;51(2):174-181

Department of Pathology and Department of Internal Medicine, University of Texas Southwestern Medical Center, Dallas, TX, USA.

The activation of the programmed cell death one (PD1)/PD1 ligand (PD-L1) immune checkpoint pathway is a mechanism of immune evasion characterized by the upregulation of PD-L1 expression by tumor cells and by the tumor microenvironment. This activation leads to the inhibition of PD1-positive T cells and to a decrease in the anti-tumor immune response. Plasmablastic lymphoma (PBL) is an aggressive type of large B-cell lymphoma with limited studies on the frequency of PD1 and PD-L1 expressions and their clinical impact. Read More

HER2-Targeted Immunotherapy and Combined Protocols Showed Promising Antiproliferative Effects in Feline Mammary Carcinoma Cell-Based Models.

Cancers (Basel) 2021 Apr 21;13(9). Epub 2021 Apr 21.

CIISA-Centro de Investigação Interdisciplinar em Sanidade Animal, Faculdade de Medicina Veterinária, Universidade de Lisboa, Avenida da Universidade Técnica, 1300-477 Lisboa, Portugal.

Feline mammary carcinoma (FMC) is a highly prevalent tumor, showing aggressive clinicopathological features, with HER2-positive being the most frequent subtype. While, in human breast cancer, the use of anti-HER2 monoclonal antibodies (mAbs) is common, acting by blocking the extracellular domain (ECD) of the HER2 protein and by inducing cell apoptosis, scarce information is available on use these immunoagents in FMC. Thus, the antiproliferative effects of two mAbs (trastuzumab and pertuzumab), of an antibody-drug conjugate compound (T-DM1) and of combined treatments with a tyrosine kinase inhibitor (lapatinib) were evaluated on three FMC cell lines (CAT-MT, FMCm and FMCp).

Exploration of High-Grade Transformation and Postoperative Radiotherapy on Prognostic Analysis for Primary Adenoid Cystic Carcinoma of the Head and Neck.

Front Oncol 2021 9;11:647172. Epub 2021 Apr 9.

Department of Pathology, National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing, China.

Background: Despite Adenoid cystic carcinoma (ACC) with cribriform or tubular components being recognized as a potentially indolent malignancy, ACC displaying solid or, more rarely, high-grade transformation (HGT) components is considered a more aggressive variant of the disease. As it is difficult to measure the proportion of the solid component objectively, and the role of HGT in the current grading system remains unclear, the prognostic influence of tumor grading remains controversial. In addition, postoperative radiotherapy (PORT) has been proven to be effective in local control of ACC of the head and neck (ACCHN) with a high rate of nerve invasion and close surgical margin.
