Another Country Heard From


From Dec. 15, 2003 PubMed: Institute of Ultrasonic Engineering in Medicine, and Clinical Center for Tumor Therapy of 2nd Hospital, Chongqing University of Medical Sciences, Box 153, 1 Medical College Road, Chongqing 400016, China. mfengwu@yahoo.com

High-intensity focused ultrasound (HIFU) is a noninvasive treatment that induces complete coagulative necrosis of a tumour at depth through the intact skin. This study was to explore the possibility of using HIFU for the treatment of patients with localised breast cancer in a controlled clinical trial. A total of 48 women with biopsy-proven breast cancer (T(1-2), N(0-2), M0) were randomised to the control group in which modified radical mastectomy was performed, and the HIFU group in which an extracorporeal HIFU ablation of breast cancer was followed by modified radical mastectomy. Short-term follow-up, pathologic and immunohistochemical stains were performed to assess the therapeutic effects on tumour and complications of HIFU. The results showed that no severe side effect was observed in the HIFU-treated patients. Pathologic findings revealed that HIFU-treated tumour cells underwent complete coagulative necrosis, and tumour vascular vessels were severely damaged. Immunohistochemical staining showed that no expression of PCNA, MMP-9, and CD44v6 was detected within the treated tumour cells in the HIFU group, indicating that the treated tumour cells lost the abilities of proliferation, invasion, and metastasis. It is concluded that, as a noninvasive therapy, HIFU could be effective, safe, and feasible in the extracorporeal treatment of localised breast cancer.

Sounds promising...

I'm hoping you can take advantage of the findings. What are the chances?

I don't know how it is in the conventional cancer camp, but drs in the "conventional" infectious diseases camp do not consider research from other countries, especially China. There is another set of drs & researchers who treat infectious diseases (and who are willing to step outside the CDC/NIH boundaries) who do read and consider non-USA research, and often come up with innovative and effective treatments-- but often at the cost of damage to their careers. Hope cancer researchers aren't as resistant to extra-USA information. Some excellent work being done outside our borders.
