Circulating tumor cells (CTCs) are a population of tumor cells mediating metastasis, which results in most of the cancer related deaths. The number of CTCs in the peripheral blood of patients is rare, and many platforms have been launched for detection and enrichment of CTCs. Enumeration of CTCs has already been used as a prognosis marker predicting the survival rate of cancer patients. Yet CTCs should be more potential. Studies on CTCs at single cell level may help revealing the underlying mechanism of tumorigenesis and metastasis. Though far from developed, this area of study holds much promise in providing new clinical application and deep understanding towards metastasis and cancer development.

Colorectal cancer (CRC) is a common malignant tumor characterized by a high degree of invasiveness, and since zinc-α2 glycoprotein (ZAG) has been implicated in the progression of several malignancies, this study was designed to investigate the role of ZAG in CRC. Its expression was assessed using the GEPIA database, and short hairpin RNA (shRNA) interference was conducted to create ZAG knockdown in CRC cell lines. We also conducted lipid synthesis, cell proliferation, apoptosis, and epithelial-mesenchymal transition (EMT) experiments to elucidate the effects of ZAG expression on CRC, as well as explored the potential underlying mechanistic pathways.

Introduction: Detection of mutations in primary tumors and liquid biopsy samples is of increasing importance for treatment decisions and therapy resistance in many types of cancer. The aim of the present study was to directly compare the efficacy of a relatively inexpensive ultrasensitive real-time PCR with the well-established and highly sensitive technology of ddPCR for the detection of the three most common hotspot mutations of , in exons 9 and 20, that are all of clinical importance in various types of cancer.
Patients And Methods: We analyzed 42 gDNAs from primary tumors (FFPEs), 29 plasma-cfDNA samples, and 29 paired CTC-derived gDNAs, all from patients with ER+ metastatic breast cancer, and plasma from 10 healthy donors.

Background: For esophageal squamous cell carcinoma (ESCC), universally accepted pathological criteria for classification by differentiation degree are lacking. Tumor budding, single-cell invasion, and nuclear grade, recognized as prognostic factors in other carcinomas, have rarely been investigated for their correlation with differentiation and prognosis in ESCC. This study aims to determine if pathological findings can predict differentiation degree and prognosis in ESCC.
