Figure 3From: Trastuzumab anti-tumor efficacy in patient-derived esophageal squamous cell carcinoma xenograft (PDECX) mouse modelsAnti-tumor efficacy of Trastuzumab in the 5 PDECX mouse models. Tumor-bearing mice were treated starting from tumor volume 100 ~ 200 mm3. The subcutaneous tumor volume was measured by caliper and calculated as mean ± SEM. Y-axis represented the volume of the tumor (mean ± SEM), and X-axis represents the number of days following treatment start day.Back to article page
