With advancements in cancer care, patient survival rates have improved significantly. However, recurrence and metastasis remain major challenges in cancer management. In Hong Kong, the accuracy and timeliness of cancer reassessment are crucial in improving patient outcomes. Traditional imaging techniques and blood tumor markers provide valuable information but often fail to detect early signs of recurrence. The RGCC Oncotrace test, utilizing liquid biopsy technology, integrates circulating tumor cell (CTC) detection, gene expression analysis, and drug sensitivity testing. This breakthrough enables early recurrence detection and personalized reassessment strategies, marking a new era in cancer surveillance.

Overview of RGCC Oncotrace Technology

Oncotrace is a liquid biopsy platform that combines multi-dimensional detection methods to assess circulating tumor cells and cancer stem cells in peripheral blood. This technology not only quantifies tumor cells but also analyzes their genetic mutations, epigenetic characteristics, and drug sensitivity, providing clinical teams with precise data for reassessment and personalized care.

Advantages and Applications of Oncotrace Testing

1. Early Recurrence Detection
• Oncotrace can detect minimal residual disease (MRD) and circulating tumor cells before visible tumors appear in imaging scans, offering an early warning system for recurrence.
• By dynamically monitoring changes in CTC count and activity, healthcare providers can identify recurrence risks and adjust follow-up plans accordingly.
2. Personalized Reassessment Strategies
• By integrating gene expression profiling and drug sensitivity analysis, Oncotrace helps identify patient-specific responses to targeted therapies and chemotherapy, aiding in personalized reassessment.
• For patients who have undergone surgery, radiation, or chemotherapy, this test provides a comprehensive evaluation of residual disease, reducing the likelihood of recurrence.
3. Non-Invasive and Convenient Testing
• Oncotrace requires only a small peripheral blood sample, eliminating the need for invasive biopsy procedures, making long-term monitoring more feasible for patients.
• With high sensitivity and specificity, it complements traditional diagnostic methods and addresses gaps in early recurrence detection.

Clinical Significance

• Dynamic Monitoring and Precision Management
  Long-term monitoring with Oncotrace provides real-time insights into tumor cell changes, allowing healthcare providers to intervene promptly when subtle changes occur.
• Personalized Decision Support for Cancer Care
  Through genetic profiling and drug sensitivity assessments, Oncotrace enables the optimization of post-reassessment care plans, improving survival rates and quality of life for cancer patients.
• Enhanced Efficiency and Cost-Effectiveness
  Compared to high-cost, invasive traditional reassessment methods, Oncotrace offers a more accessible, cost-effective approach that enhances overall cancer management in Hong Kong.

Conclusion

In Hong Kong, where the need for cancer reassessment is growing, the RGCC Oncotrace test introduces a revolutionary approach with its multi-dimensional, precise, and non-invasive features. By enabling dynamic monitoring of circulating tumor cells and cancer stem cells, Oncotrace provides an early warning system for recurrence and supports the development of personalized reassessment strategies. As this technology continues to advance, it is poised to play a crucial role in the future of cancer surveillance, ushering in a new era of precision oncology.
