Figure 6.
Anti-tumor effect of laser immunotherapy (LIT) in treating cutaneous squamous cell carcinoma (cSCC) in SKH-1 mice. (A) Temperature in tumor tissue during laser treatment. Left: Thermographic image showing the temperature of the tumor in one mouse with 808-nm laser illumination. Right: The temperature increase curve of the tumors with 808-nm laser illumination. (B) Tumor volume changes in different treatment groups. Statistical analysis for tumor volume changes was performed by t-test (day 27: Laser, or LIT group vs. Control group,*p < 0.05; Day 60: LIT group vs. Laser group, ##p < 0.01). (C) Representative photographs of mice at different times after treatments. (D) Survival rates of cSCC tumor bearing mice in different treatment groups.
