Judy S Crabtree

Front Oncol 2022 7;12:901435. Epub 2022 Jun 7.

Department of Genetics, Louisiana State University Health Sciences Center, New Orleans, LA, United States.

Gastroenteropancreatic neuroendocrine neoplasms are a rare, diverse group of neuroendocrine tumors that form in the pancreatic and gastrointestinal tract, and often present with side effects due to hormone hypersecretion. The pathogenesis of these tumors is known to be linked to several genetic disorders, but sporadic tumors occur due to dysregulation of additional genes that regulate proliferation and metastasis, but also the epigenome. Epigenetic regulation in these tumors includes DNA methylation, chromatin remodeling and regulation by noncoding RNAs. Read More

Enhancer of Zeste Homolog 2 (EZH2) Is a Marker of High-Grade Neuroendocrine Neoplasia in Gastroenteropancreatic and Pulmonary Tract and Predicts Poor Prognosis.

Cancers (Basel) 2022 Jun 8;14(12). Epub 2022 Jun 8.

Institute of Pathology, University Medical Center Goettingen, Georg-August-University, 37075 Goettingen, Germany.

Tumor grading is a robust prognostic predictor in patients with neuroendocrine neoplasms (NEN) and guides therapy, especially in tumors with high proliferation. NEN can be separated into well-differentiated and poorly differentiated types. The more aggressive NEN have been further separated into neuroendocrine tumors (NET G3) with a better prognosis and neuroendocrine carcinomas (NEC) with a worse prognosis. Read More

Dipartimento di Scienze Veterinarie, Università di Pisa, Viale delle Piagge, 2, 56124, Pisa, Italy.

The mouse mammary tumour virus (MMTV) is implicated in the aetiology of murine mammary carcinomas and a variant of it, the type B leukemogenic virus, can cause murine thymic lymphomas. Interestingly, a MMTV-like virus is suspected to be involved in human breast cancer and feline mammary carcinomas.

Department of Neurology, Jeonbuk National University Medical School and Hospital, 20 Geonji-ro, Deokjin-gu, Jeonju 54907, Korea.

Cognitive impairment in cancer patients can be caused by various factors; in approximately 30% of cancer patients, the symptoms appear before starting treatment. Paraneoplastic limbic encephalitis (PLE) is a rare disease associated with an autoimmune response, and is characterized by memory loss, depression, and personality changes; it is one of the potential causes of cognitive dysfunction in cancer patients. Two patients were previously diagnosed with mild cognitive impairment and maintained clinical stability; after suffering a rapid change in personality and sudden cognitive decline, colorectal cancer was diagnosed within a few months.

Antiangiogenic Drug-Induced Proteinuria as a Prognostic Factor in Metastatic Colorectal Cancer.

Curr Oncol 2022 May 31;29(6):3996-4011. Epub 2022 May 31.

Immunology Department, "Grigore T. Popa" University of Medicine and Pharmacy, 700115 Iasi, Romania.

Treatment with bevacizumab is known to cause adverse events such as proteinuria and hypertension, amongst others. However, while bevacizumab-induced hypertension has been linked to increased overall survival (OS), data on proteinuria are controversial. We performed a retrospective analysis to observe the influence of adverse events developed during treatment with bevacizumab and chemotherapy on the OS in patients with metastatic colorectal cancer (mCRC).

[Neutropenic enterocolitis in the pediatric cancer patient].

Rev Chilena Infectol 2022 02;39(1):59-69

Hospital Clínico San Borja Arriarán, Chile.

Neutropenic enterocolitis (NEC) is a heterogeneous disease of the gastrointestinal tract with systemic response, that corresponds to a severe and life-threatening clinical condition in immunocompromised patients, especially in childhood cancer. The pathologic features are poorly understood, although its multifactorial cause of NEC is well established and it is associated with the cytotoxic effects of the chemotherapy agents used and recognized by the classic triad of fever, neutropenia, and abdominal pain, secondary to gastrointestinal injuries that alters mucosal permeability and helps intramural bacterial invasion. NEC is truly a clinical challenge that requires an early diagnosis and a multidisciplinary approach including basic laboratory and imagological tests in high complexity centers. Read More

ARIH2 regulates the proliferation, DNA damage and chemosensitivity of gastric cancer cells by reducing the stability of p21 via ubiquitination.

Cell Death Dis 2022 Jun 22;13(6):564. Epub 2022 Jun 22.

State Key Laboratory of Silkworm Genome Biology, Southwest University, 400716, Chongqing, China.

Ariadne homolog 2 (ARIH2) is a key member of the RING-between-RING (RBR) E3 ligase family, which is characterized by an RBR domain involved in the polyubiquitination process. However, the molecular mechanism and biological function of ARIH2 in the pathogenesis of gastric cancer remain unclear. In this paper, we found that high ARIH2 expression is correlated with poor prognosis in gastric cancer patients and that ARIH2 can significantly promote the proliferation of gastric cancer cells.

Vaccines for immunoprevention of DNA mismatch repair deficient cancers.

J Immunother Cancer 2022 Jun;10(6)

University Hospital Heidelberg, Institute of Pathology, Department of Applied Tumor Biology, Heidelberg, Germany.

The development of cancer vaccines to induce tumor-antigen specific immune responses was sparked by the identification of antigens specific to or overexpressed in cancer cells. However, weak immunogenicity and the mutational heterogeneity in many cancers have dampened cancer vaccine successes. With increasing information about mutational landscapes of cancers, mutational neoantigens can be predicted computationally to elicit strong immune responses by CD8 +cytotoxic T cells as major mediators of anticancer immune response.
