Task: Answer Verification
Input (English): Question: Does blood presence of circulating oncofetal fibronectin mRNA , by RT-PCR , represent a useful specific marker for the management and follow-up of thyroid cancer patients?
Answer: We underline how the complexity of onfFN transcripts could affect the RT-PCR procedure. In addition, the presence of onfFN transcripts in several normal and cancer tissues, along with non-thyroid biological fluids or cells, does not allow the use of this marker for cancer monitoring.
Output (English): no
