Abstract

Lymph node metastasis has a significant contribution to the prognosis of epithelial ovarian cancer but the role of lymph node dissection in treatment is not clear. In this study, we aimed to retrospectively determine the effect of the number and localization of lymph nodes removed and the number of metastatic lymph nodes on survival. In this study, we retrospectively reviewed the data of 378 patients (210 patients with lymph node dissection and 168 patients with no dissection) who underwent primary surgery between 2004 and 2014 in various centers with epithelial ovarian cancer diagnosis and followed up in our medical oncology clinic. Demographic and histopathologic features, stage, Ca 125 levels, chemotherapy responses of these patients were examined and survival analyzes were performed. The median age of the patients was 52 years (range 16-89) and median follow-up duration was 39 months (range 1-146). During the analysis, 156 patients (41%) died and 222 patients (59%) were alive. Patients who underwent lymphadenectomy had significantly improved progression free survival (PFS) (18 vs 31 months, P < 0.05) and overall survival (OS) (57 vs 92 months, P < 0.05). OS was longer in patients with >10 lymph nodes removed compared to pat...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
