Design outcomes

Primary

MeasureTime frame
The accuracy of positive rate of the lymph node metastasis using the spectroscopy.

Secondary

MeasureTime frame
We evaluate the lymph nodes, the main tumor and the other lesions suspected metastasis to the following items. *The diagnosability by spectroscopy, fluorescent observation and white light observation. *The relationship between histological type and spectrum. *The relationship between tumor volume and spectrum. *The appropriate cut off value of fluorescent intensity. *The effectiveness of the spectroscope compared with VLD-EX(SBI Pharma).
