Limited but definite efficacy of prophylactic hepatic arterial infusion chemotherapy after curative resection of colorectal liver metastases: A randomized study

T TonoN Kikkawa


Greater than 50% of patients who undergo curative resection of liver metastases from colorectal carcinoma develop recurrent disease in the residual liver. Although several studies have attempted to use hepatic arterial infusion (HAI) chemotherapy to prevent recurrence, to the authors' knowledge the efficacy of the treatment has not yet been determined. Nineteen patients who underwent curative hepatectomy for metastatic colorectal carcinoma randomly were assigned into the HAI group (nine patients) or the control group (ten patients). Patients in the HAI group received continuous intraarterial infusion of 5-fluorouracil (5-FU) (500 mg/day) for 4 days followed by a 3-day rest. The treatment was continued for 6 weeks. The median follow-up period was 62.2 months. The recurrence was confirmed in three patients in the HAI group and in eight patients in the control group. Of these, recurrence in the remnant liver was observed in one patient and in six patients, respectively. The median disease free interval after hepatectomy was 62.6 months in the HAI group and 13.8 months in the control group. The 1-year, 2-year, and 3-year disease free survival rates were 77.8%, 77.8%, and 66.7%, respectively, in the HAI group and 50.0%, 30.0%, and 2...Continue Reading

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.

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.

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.
