Power and Promise of Next-Generation Sequencing in Liquid Biopsies and Cancer Control.

Traditional methods of cancer treatment are usually based on the morphological and histological diagnosis of tumors, and they are not optimized according to the specific situation. Precision medicine adjusts the existing treatment regimen based on the patient's genomic information to make it most suitable for patients. Detection of genetic mutations in tumors is the basis of precise cancer medicine.

New Therapeutic Options for Advanced Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC), one of the most common lethal diseases in the world, has a 5-year survival rate of only 7%. Hepatocellular carcinoma has no symptoms in the early stage but obvious symptoms in the late stage, leading to delayed diagnosis and reduced treatment efficacy. In recent years, as the scope of HCC research has increased in depth, the clinical development and application of molecular targeted drugs and immunotherapy drugs have brought new breakthroughs in HCC treatment.
