Early detection and consistent monitoring are key to improving outcomes for throat cancer patients. Advances in liquid biopsy technology now make it possible to detect recurrence through a simple blood test. At AQ Surgery, led by Dr. Anastasiya Quimby, MD, DDS, throat cancer patients in West Palm Beach benefit from Signatera, an innovative test that identifies cancer recurrence earlier than traditional imaging. Here’s how this next-generation test is transforming throat cancer monitoring and enhancing patient care.
Understanding Signatera: A Personalized Blood Test
Signatera is an advanced liquid biopsy test that detects circulating tumor DNA (ctDNA) in a patient’s blood. Unlike standard tests that look for general cancer markers, Signatera creates a personalized DNA profile based on the exact genetic mutations found in an individual’s tumor. This allows for precise, patient-specific monitoring that can identify even the smallest traces of cancer activity.
After surgery or biopsy, a sample of the patient’s tumor is sequenced to pinpoint its unique DNA mutations. That information is used to design a custom Signatera test capable of detecting whether any tumor-specific DNA remains in the bloodstream. By performing regular blood tests, Dr. Quimby can monitor ctDNA levels over time, gaining timely insight into treatment effectiveness and potential recurrence.
The Process: What Patients Can Expect
Once the tumor DNA is sequenced following throat cancer surgery or biopsy, blood samples are collected on a routine schedule, typically every few months or as recommended based on treatment progress. Each test measures the presence or absence of ctDNA:
- If ctDNA is detected: This may indicate that cancer cells are still present or that recurrence is beginning.
- If ctDNA is not detected: It suggests there is no detectable cancer activity at that time.
By comparing results across multiple tests, Dr. Quimby can quickly identify trends and make informed adjustments to treatment, ensuring that every patient receives timely, targeted care.
Benefits of Throat Cancer Monitoring With Signatera
These advantages make Signatera a valuable part of ongoing throat cancer management:
- Early detection of recurrence: Detects microscopic cancer traces months before imaging scans reveal visible changes, enabling early, proactive intervention.
- Personalized precision: Tailored to each patient’s tumor DNA, Signatera offers unmatched accuracy in identifying residual disease or recurrence.
- Non-invasive and convenient: Requires only a blood draw, making it a comfortable, repeatable alternative to traditional biopsies or radiation-based monitoring.
- Real-time treatment adjustments: Continuous ctDNA tracking helps Dr. Quimby adapt therapies promptly based on biological response rather than waiting for imaging changes.
- Peace of mind and quality of life: Because Signatera delivers clear, personalized results quickly, patients gain reassurance and confidence throughout their recovery.
Who Should Consider Signatera Testing
Signatera is clinically validated for head and neck cancers, including throat cancer. It benefits patients who are undergoing active treatment, have completed therapy, or are in remission. It is especially valuable for:
- Patients who have completed surgery, chemotherapy, or radiation therapy
- Individuals at high risk of recurrence based on cancer stage or medical history
- Patients seeking long-term, personalized follow-up without invasive procedures
These benefits make Signatera particularly effective for those requiring ongoing, precise cancer surveillance.
