Hypothesis
The study investigates the impact of multifocal high energy shock waves (HESW) on tumor blood flow and ATP concentration.
Conclusion
Multifocal HESW significantly reduces blood flow and ATP levels in tumors and adjacent tissues.
Supporting Evidence
- Blood flow and ATP concentration were significantly reduced in treated tumors compared to controls.
- Three hours after treatment, blood flow and ATP levels returned to background levels.
- HESW treatment resulted in a significant decrease in tumor growth for four days.
Takeaway
This study shows that using special shock waves can hurt tumors by cutting off their blood supply and energy.
Methodology
The study used autoradiography and bioluminescence to measure blood flow and ATP levels in treated and untreated tumors in hamsters.
Limitations
The study was limited to a small sample size and only one type of tumor.
Participant Demographics
Male Syrian Golden Hamsters, 9-11 weeks old, weighing 80-100 g.
