Primary cystic neuroendocrine tumor of the liver: case report

Rev Med Inst Mex Seguro Soc 2019 Jan 28;56(5):505-509. Epub 2019 Jan 28.

Instituto Mexicano del Seguro Social, Hospital de Especialidades "Dr. Bernardo Sepúlveda Gutiérrez", Servicio de Anatomía Patológica. Ciudad de México, México

Background: 85% of neuroendocrine tumors (NET) originate in the gastrointestinal tract, which is why their primary hepatic location is very rare; NETs most frequently cause metastases to the liver; so when diagnosed, a hepatic NET is considered initially metastatic. Diagnosis of primary hepatic neuroendocrine tumors (PHNET) should be performed by excluding extrahepatic NETs and through histological confirmation. The objective of this article is to present a case of PHNET. Read More

Molecular characterisation and liquid biomarkers in Carcinoma of Unknown Primary (CUP): taking the 'U' out of 'CUP'.

Br J Cancer 2019 Jan 23;120(2):141-153. Epub 2018 Dec 23.

The Christie NHS Foundation Trust, Wilmslow Road, Manchester, M20 4BX, UK.

Cancers of Unknown Primary (CUP) comprise a heterogeneous clinical entity of confirmed metastatic cancer where the primary site of origin is undetectable. It has a poor prognosis with limited treatment options. CUP is historically under-researched; however, understanding its biology has the potential to not only improve treatment and survival by implementation of biomarkers for patient management, but also to greatly contribute to our understanding of carcinogenesis and metastasis across all cancer types.

Combination of panendoscopy and positron emission tomography/computed tomography increases detection of unknown primary head and neck carcinoma.

Laryngoscope 2018 11 8;128(11):2573-2575. Epub 2018 Sep 8.

Department of Facial Plastic and Reconstructive Surgery , Otolaryngology and Facial Plastic Surgery Associates, Fort Worth, Texas, U.S.A.

Objectives/hypothesis: With positron emission tomography/computed tomography (PET/CT) now commonplace as a diagnostic tool, new questions have arisen regarding the utility and cost-effectiveness of panendoscopy. In this retrospective review of a large cohort of head and neck squamous cell carcinoma of unknown primary (HNSCC-UP), we describe the enduring utility of panendoscopy in the detection of the primary site of mucosal disease even when PET/CT is negative.

Study Design: Retrospective cohort study. Read More

Diffuse Bone Marrow Metastasis as the Initial Presentation of an Occult Breast Cancer.

Case Rep Oncol Med 2018 22;2018:2946409. Epub 2018 Jul 22.

Department of Radiology, Changhua Hospital, Ministry of Health and Welfare, Chang-Hua County, Taiwan.

Introduction: Breast cancer is one of the malignancies which tend to involve the bone marrow, but initial presentation with diffuse bone marrow metastasis from an occult breast cancer is very rare. Prognosis is generally very poor for marrow metastasis from solid tumors except that breast cancer is a treatable disease even in such a dismal condition.

Case: A 64-year-old woman's headache was found to result from diffuse adenocarcinoma metastasis in the bone marrow from an unknown primary site. Read More

Front Immunol 2018 30;9:1767. Epub 2018 Jul 30.

Department of Oncology, Linköping University, Linköping, Sweden.

Fat is a major tissue component in human breast cancer (BC). Whether breast adipocytes (BAd) affect early stages of BC metastasis is yet unknown. BC progression is dependent on angiogenesis and inflammation, and interleukin-8 (IL-8) and vascular endothelial growth factor (VEGF) are key regulators of these events. Read More
