Summary
This summary is machine-generated.Platelet aggregation function, including max aggregation ratio, is linked to colorectal cancer progression. These platelet parameters show potential clinical value in predicting tumor advancement and recurrence.
Area Of Science
- Oncology
- Hematology
- Biomarkers
Background
- Colorectal cancer (CRC) is a significant global health concern.
- Understanding factors influencing CRC progression is crucial for early detection and treatment.
- Platelets play a role in cancer, but their specific association with CRC clinicopathological features requires further investigation.
Purpose Of The Study
- To investigate the relationship between platelet aggregation function, platelet count, mean platelet volume, and clinicopathological characteristics of colorectal cancer.
- To determine if these platelet parameters can serve as indicators for CRC malignancy, prognosis, recurrence, and metastasis.
Main Methods
- A cohort study involving 546 colorectal tumor patients and 118 healthy controls.
- Measurement of platelet aggregation parameters (max aggregation ratio, average aggregation ratio, max aggregation time) using arachidonic acid and adenosine diphosphate.
- Analysis of clinicopathological data including malignancy, prognosis, recurrence, and metastasis.
- Receiver operating characteristic (ROC) analysis to evaluate the predictive significance of platelet indexes.
Main Results
- Max aggregation ratio, average aggregation ratio, and platelet count were significantly associated with colorectal cancer progression (P < 0.05).
- Max aggregation ratio induced by arachidonic acid demonstrated the strongest predictive capability for cancerization, radical operation, and recurrence/metastasis, with AUC values ranging from 0.649 to 0.685.
- Platelet count also showed a correlation with tumor progression.
Conclusions
- Platelet aggregation function, specifically the max aggregation ratio, is correlated with colorectal tumor progression.
- These findings suggest a potential clinical utility for platelet aggregation parameters in assessing colorectal cancer advancement and outcomes.

The platelet phase, the second stage of hemostasis, commences around 15-20 seconds after an injury. It follows and overlaps with the vascular phase, during which blood vessels constrict to minimize blood loss.
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.
