Implications of clinical risk score to predict outcomes of liver-confined metastasis of colorectal cancer

Abstract

We investigated the usefulness of a clinical risk scoring system (CRS) for guiding management and defining prognosis for patients with colorectal liver met"astases (CLM). We retrospectively analyzed data about the correlation between outcomes and Fong's CRS from 1989 to 2010 for patients treated for CLM at the Severance Hospital. Of 566 patients, 232 received adjuvant treatment after liver resection. Of these patients, 185 (81%) had a low CRS (0-2) and 47 (19%) had a high CRS (3-5). Stratification into high and low CRS allowed significant distinction between Kaplan-Meier curves for outcome. The 5-year survival rate was 88.5% and 11.5% among patients with a low and high CRS, respectively (P < 0.001). Seventy patients with initially unresectable CLM underwent liver resection after tumor downsizing by induction chemotherapy. Shifting of the CRS from high to low (8 patients; 11.4%) improved disease-free survival and overall survival. High CRS is associated with worse survival after resection in resectable and unresectable disease. The CRS may be used for risk assessment when recommending oncological surgical timing in initially unresectable disease and treatment options for perioperative or adjuvant treatment in resectable disease.

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.
