主要结果指标

措施说明 |
大体时间 |
---|---|---|
Parameters derived from the optical images acquired with the DOT system
大体时间:These parameters will be obtained from patients during neoadjuvant chemotherapy process, which is up to an average of 6 months
|
The primary parameters derived from the optical images acquired with the DOT system include: The volume of tumor microvasculature V, the total haemoglobin concentration (THC), and the blood volume index BVI (=VC). Other available optical parameters are: blood oxygenation in the tumor microvasculature (SO2), its spatial distribution and dynamic fluctuation; dynamic blood perfusion. These parameters will be compared with histopathological response. |
These parameters will be obtained from patients during neoadjuvant chemotherapy process, which is up to an average of 6 months

Change in DOT parameters such as BVI, SO2, blood perfusion dynamic fluctuation
大体时间:These parameters will be obtained from patients during neoadjuvant chemotherapy process, which is up to an average of 6 months
|
The change in DOT parameters such as BVI, SO2, blood perfusion dynamic fluctuation will be correlated with response based on clinical examination, ultrasound, MMG and MRI. Standard definitions for clinical response will be used to classify patients into four categories: complete response (CR), partial response (PR), progressive disease (PD) and stable disease (SD). |
These parameters will be obtained from patients during neoadjuvant chemotherapy process, which is up to an average of 6 months
