Summary: CTMs represent cancer cells detached from solid tumors and can provide insights into metastatic mechanisms. Analyzing CNAs in CTMs, which often contain unknown fractions of leukocytes, presents challenges. By titrating known numbers of leukocytes into cancer cells, we generated tumor fractions ranging from 0-100%. Through low-pass sequencing and the use of ichorCNA algorithm, we accurately predicted the tumor fraction of CTMs isolated from early-stage breast cancer patients. These CTMs were found to contain cancer cells with a range of 8-48%, with notable differences in CNAs compared to matched primary tumors, suggesting potential implications for metastasis-related genes that should be further explored.

Summary: Circulating tumor cells (CTCs) and/or circulating tumor microemboli (CTM) from non-small cell lung cancer (NSCLC) patients could serve as a non-invasive tool for prognosis, acting as liquid biopsy. This study found that CTCs/CTMs from NSCLC patients expressed immune evasion markers TGF beta RI/CD47, and the presence of CTMs CD47+ was associated with poor progression-free survival (PFS).

Summary: Gastric cancer is a highly malignant tumor with poor prognosis, and early diagnosis and effective monitoring are crucial for reducing disease burden and mortality. Blood-based biomarker assays have the potential for early-stage detection of gastric cancer. However, the currently used tumor marker assays have limitations in sensitivity and specificity. In recent years, multiple markers have been identified and tested for their clinical relevance in gastric cancer management. This review summarizes the available literature on various blood-based biomarkers and discusses their potential for early diagnosis and accurate prediction of therapeutic approaches.

Summary: Circulating tumor cells (CTCs) are shed from primary tumor or metastatic sites into the bloodstream and subsequently seed into distant tissues, serving as precursors of metastases. Gastric cancer (GC) is highly heterogeneous, making secondary pathological biopsy difficult and invasive examination harmful. In recent years, CTCs have shown great potential for tumor diagnosis, prognosis prediction, efficacy detection, and treatment guidance, although their role in GC remains limited. This review focuses on landmark studies demonstrating the technical approaches of CTCs monitoring in GC and highlights the clinical application of CTCs numbers and phenotypes in monitoring therapeutic efficacy and predicting patient prognosis through sequential blood analyses.

Summary: Circulating tumor cells (CTC) are associated with the prognosis of patients with gastric cancer. Gastric cancer patients with positive CTC may have a poorer prognosis compared to those with CTC-negative tumors. CTC-positive patients have more advanced TNM staging, poorer tumor differentiation, and earlier distant metastasis.

Summary: CTCs can be used for predicting recurrence in CRC patients. CTC clusters/microemboli have higher correlation with metastasis, and when both the number of CTCs and serum CEA levels are high, the prognosis in CRC patients may be worse.

Summary: A semiautomated method proposed in this study predicts CRC based on counting CTCs, using features identified by SVM. The wrapping degree of cytoplasm around the nucleus is introduced to improve results. Semiautomated identification was found to be nearly as accurate and much faster than manual identification for detecting CRC.

Summary: Circulating tumor cells (CTCs) are rare in blood, but play a crucial role in metastasis and have potential as a biomarker for cancer diagnosis, prognosis, and treatment monitoring. Advancements in CTC isolation techniques have improved detection sensitivity and accuracy, leading to increased focus on molecular characterization and understanding interactions between CTCs and associated cells for precision medicine. Challenges and opportunities in clinical utilization of CTCs are being addressed for future advancements in cancer research.

Summary: In this study, circulating tumor cells (CTCs) were detected in the peripheral blood of tumor patients, and their numbers and subtypes were found to be related to different tumor diseases and stages. CTCs with mesenchymal phenotypes were closely associated with lymph node or vascular metastasis. CTC detection can aid in early diagnosis of tumor diseases and monitoring of disease progression.

Summary: This study investigates the relationship between gene expression patterns and phenotypic plasticity and heterogeneity in colorectal cancer (CRC). The results demonstrate the interconnectedness between different Consensus Molecular Subtypes (CMS) of CRC and specific phenotypes such as epithelial and mesenchymal characteristics. Additionally, the study reveals correlations between metabolic pathways and phenotypic scores, as well as between PD-L1 activity and mesenchymal phenotype. Single-cell RNA sequencing analysis further confirms the heterogeneity of different CMS subtypes. These findings have important implications for understanding CRC heterogeneity and developing targeted therapies.

Summary: The study demonstrates that loss of FLASH in cancer cells leads to a hybrid E/M phenotype with high epithelial scores, suggesting FLASH acts as a repressor of the epithelial phenotype. Additionally, FLASH expression is inversely correlated with the epithelial score and subsets of mesenchymal markers are distinctly up-regulated in FLASH, NPAT, or SLBP-depleted cells.

Summary: Cancer heterogeneity and drug resistance are major obstacles to effective cancer treatment, and epigenetic modifications play a pivotal role in these processes. This review explores essential epigenetic modifications, including DNA methylation, histone modifications, and chromatin remodeling, and discusses their complex contributions to cancer biology. However, the interplay of epigenetic and genetic changes in cancer cells presents unique challenges that must be addressed to fully exploit the potential of epigenetic modifications.

Summary: The glycocalyx, a protective barrier surrounding cells, has been found to play a role in cancer cell proliferation, survival, and metastasis. However, its function in maintaining DNA/nuclear integrity during migration through dense matrices has not been explored. This study shows that the bulkiness of the glycocalyx is inversely associated with nuclear stresses, and highlights its mechanical role in shielding migration-associated stresses.
