About

To evaluate the change of blood perfusion before/after the use of Endostar, discuss the time sequence of Endostar TM in treating advanced lung adenocarcinoma in normalization window period.

Enrollment: 20 estimated patients

Sex: All

Ages: 18 to 70 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Histologically or cytologically newly diagnosed as unresectable and metastasis advanced lung adenocarcinoma(Stage IV, Seventh Edition of the UICC/AJCC Classification for Lung Cancer).
• At least one measurable objective tumor lesion, spiral CT or PET-CT examination: the shortest diameter ≥2cm，and no obvious necrosis
