Summary: Based on the assessment of CTCs, this study found that CEP8 and CK-positive CTCs have the potential to improve the risk stratification of stage II CRC patients. In the subgroup with clinical high risk, the number of preoperative CTCs is associated with treatment outcome. Moreover, if postoperative CTC levels remain above 4 for more than three consecutive time points, the recurrence rate is 100%.

Summary: This study analyzed the distribution of immune cell subpopulations in peripheral blood samples from pancreatic cancer patients and investigated their correlation with clinical parameters and prognosis. The study found that pancreatic cancer patients had a decreased proportion of lymphocytes and an increased CD4/CD8 ratio. Increased proportions of lymphocytes and NKT cells were observed more frequently in patients over 60 years and in patients with metastasis. Furthermore, post-operative pancreatic cancer patients had significantly reduced proportions of CD4(+)T cells, B cells, and CD4/CD8 ratio, while the frequency of CD8(+)T cells and NKT cells was significantly elevated. Kaplan-Meier analysis indicated that patients with high lymphocyte proportion had prolonged overall survival.

Summary: In the past few decades, there have been developments in tumor diagnosis and treatment theory. However, pancreatic cancer mortality is increasing while the mortality rate of other common tumors is decreasing. Traditional imaging methods and biomarkers lack sensitivity and specificity for early micrometastasis detection. Circulating tumor cells (CTCs) have emerged as a non-invasive and real-time liquid biopsy technique with potential for analyzing tumor characteristics and serving as an independent prognostic factor.

Summary: Portal venous circulating tumor cells (CTCs) can serve as a biomarker for early recurrence and poor prognosis in patients with resectable pancreatic cancer. The number of CTCs is associated with stage and regional lymph node metastasis, and low portal venous CTCs are associated with better overall and recurrence-free survival.

Summary: This study found that circulating tumor cells (CTCs) could be used for the diagnosis of pancreatic ductal adenocarcinoma (PDAC) and had comparable sensitivity and specificity to CA199. Combining CA199 and CTC number could significantly improve the diagnostic performance of PDAC. CTC subtype was inferior to CTC number as a diagnostic marker.

Summary: Despite advancements in PC diagnosis and treatment, clinical outcomes remain poor and there is a lack of effective prognostic biomarkers. CTCs, a promising biomarker, are rare in peripheral blood, but portal blood may offer better detection rates. Portal CTC counts are associated with hepatic metastasis, recurrence, and survival, providing information on tumor heterogeneity and prognosis. However, more prospective studies are needed to validate portal CTCs as a biomarker in PC.

Summary: Pancreatic cancer is a highly dangerous disease, and understanding its progress and regression is crucial. Exosomes derived from various cells, including tumor cells, can impact the tumor microenvironment and play a role in cancer development. Detecting specific molecules carried by exosomes in blood and body fluids can aid in early diagnosis and monitoring of pancreatic cancer. Additionally, immune cell-derived exosomes and mesenchymal stem cell-derived exosomes have the potential for pancreatic cancer treatment through enhancing anti-tumor properties or drug loading. Overall, exosomes form a complex communication network that is involved in pancreatic cancer progression, diagnosis, monitoring, and treatment.

Summary: This study aimed to detect and describe the distribution characteristics of circulating tumor cells (CTCs) and circulating tumor-derived endothelial cells (CTECs) in patients with advanced lung cancer, and explore the correlation between CTC/CTEC subtypes and novel prognostic biomarkers. CTCs and CTECs derived from 52 patients with advanced lung cancer were identified using the subtraction enrichment-immunofluorescence in situ hybridization (SE-iFISH) system.

Summary: This study aimed to investigate the effect of preoperative CTCs on postoperative recurrence and overall survival prognosis of pancreatic head cancer. The results showed that preoperative CTCs were significantly correlated with tumor invasion and postoperative metastasis, and were independent risk factors for DFS and OS.
