About the trial

This is a prospective and observational study, aiming to determine the detection rate and change of CtDNA in blood samples of cancer patients before, during and after neoadjuvant treatment. * Determine the rate of ctDNA positivity at the time before treatment, * Determine the rate of ctDNA positivity at the time during treatment, * Determine the rate of ctDNA positivity at the time after neoadjuvant therapy, whether there is a change in ctDNA expression of the study population during treatment. And aiming to investigate the relationship between ctDNA expression and MRI imaging with pCR response in neo-adjuvant therapy: * Correlation between ctDNA detection and pCR response. Determine the percentage of Positive Prediction Value - PPV, Negative Prediction Value - NPV of ctDNA, * Correlation between MRI imaging and pCR response. Determination of PPV, NPV of MRI * Combination of ctDNA detection and MRI imaging in the prognosis of pCR. Determination of PPV, NPV ratio of ctDNA combined with MRI.
