Background: Circulating tumor cells (CTCs) have been investigated as a potential biomarker for predicting prognosis and monitoring therapeutic responses in colorectal cancer (CRC). However, the sensitivity of CTCs detection is low, thus limiting the clinical utility of CTCs. We aim to examine the clinicopathological parameters that improve prognosis prediction for CRC using CTCs as a biomarker.

Methods: We enumerated CTCs in 186 CRC patients and associated the number of CTCs with the clinicopathological features and overall survival (OS) using a univariate and multivariate Cox regression model and Kaplan-Meier survival analysis.

Results: The presence of CTCs from 186 CRC patients was significantly associated with stage, preoperational carcinoembryonic antigen (CEA), and CA19-9 levels. Using Kaplan-Meier survival and Cox regression analysis, patients with five or more CTCs exhibited significantly worse OS compared to patients with fewer than five CTCs. The combination of CTCs with tumor marker CEA has a better OS prediction than individual CTCs or CEA and serves as a more effective prediction model in patients with CRC.

Conclusion: We identified that patients with more than five CTCs exhibited significantly worse OS. Additionally, patients with the normal level of CEA, but who also had more than five CTCs trended towards a worse OS.

Circulating tumor cells (CTCs) drive metastasis, the leading cause of death in individuals with breast cancer. Due to their low abundance in the circulation, robust CTC expansion protocols are urgently needed to effectively study disease progression and therapy responses. Here we present the establishment of long-term CTC-derived organoids from female individuals with metastatic breast cancer.

Circulating Tumor Cells (CTCs) in blood encompass DNA, RNA, and protein biomarkers, but clinical utility is limited by their rarity. To enable tumor epitope-agnostic interrogation of large blood volumes, we developed a high-throughput microfluidic device, depleting hematopoietic cells through high-flow channels and force-amplifying magnetic lenses. Here, we apply this technology to analyze patient-derived leukapheresis products, interrogating a mean blood volume of 5.

Introduction: The clinical benefits of combining immunotherapy with chemotherapy and surgical resection in pancreatic adenocarcinoma remain unclear. The expression and clinical significance of HIF1A in circulating tumor cells (CTCs) in pancreatic adenocarcinoma remains limited.

Methods: This retrospective cohort study compared survival outcomes in pancreatic adenocarcinoma patients treated with two regimens: surgery+chemotherapy (nab-paclitaxel plus gemcitabine)+anti-PD1 (Tislelizumab) (S+AG+anti-PD1), and surgery+chemotherapy (S+AG).

Parathyroid carcinoma (PC) is a rare malignancy, comprising 1 % of all cases of primary hyperparathyroidism (PHPT). This narrative review explores recent advances in PC management, with a focus on molecular insights, diagnostic advancements, surgical innovations, and emerging targeted therapies. Manuscripts published between 2023 and 2024 were obtained from PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL).

Article Synopsis
  • Detecting circulating tumor cells (CTCs) is tough because they are present in low numbers and vary in characteristics, with traditional methods struggling for those with low EpCAM expression.
  • This study introduces a new approach using silica-coated magnetic nanobeads with streptavidin for better CTC capture.
  • The new method showed higher capture rates for specific cancer cell lines, especially those with low EpCAM expression, indicating its potential for improving CTC detection compared to existing commercial options.
