New technology to treat cancer
The future, the tumor, “directed blast”?
Although cancer mortality remains high, but cancer treatment is still in progress, so a lot of people see hope. For example, radiation therapy after several years of development have made great progress, the first is the X-ray, then the r-ray, and in the future, proton beam radiation therapy is a treatment which is best. Proton therapy can be precisely “targeted fixed-point burst” technology, the vital organs and tissues from damage, so as to solve children’s problems in radiation therapy patients, it was predicted that proton radiation therapy in the next 20-30 years will be a cancer radiation therapy mainstream means. Also suggested that perhaps the future, can people get rid of the tumor cells to treat problems, tumors, is a multi-factor, multiple genes involved in the complex process, but in the end, and human immune cells, immune recognition and clearance, “incompetent” relevant. In this sense, need to be immune to any cancer treatment. Currently, the dendritic cells in the body’s immune system is equivalent to the “radar”, can provide information about the tumor gives the existence of normal body cells with anti-tumor activity. In short, cell therapy is man-made “education” cancer patient’s own dendritic cells, so that they identify themselves with information about the tumor, thereby breaking immune tolerance, specifically kill the tumor.
According to Dr. Du Minghua, director of University Hospital Department of Nuclear Medicine Introduction, we all know B-, is the use of ultrasound to work, if the frequency is lower that some tumors on his special “allergy.” ”We have a total of 18 cases of cancer patients has been tested and found 17 cases, tumors or reduced or stable, very significant effect.” Expert told reporters, treatment of carbon dioxide microbubble agent intravenously to cancer patients the blood vessels, the use of ultrasound to target tumor angiogenesis through the site of treatment required to pass low-power ultrasound, the role of thermal effects in the body, blocking the tumor’s nutrient channel, to “starve the tumor,” the purpose, resulting in local tumor necrosis, thus to tumor size, control of tumor progression. The treatment for each treatment time is generally 20 to 30 minutes, without surgery, is home and abroad.
Ultrasound so powerful, will also “starve” normal organizations? Experts explained that the tumor tissue and normal tissue blood vessels are not the same vessel wall much thinner than normal tissue, and more easily “broken”, the design frequency ultrasound just to starve the tumor, normal tissue hungry. However, this method is not suitable for all cancer patients must be able to reach the ultrasonic range, such as liver cancer, breast cancer, thyroid cancer, and brain tumors and other tumors are helpless.
Recently, Nanjing Drum Tower Hospital also conducted a special operation, such as “microwave” as burn the tumor. Drum Tower Hospital, Urology Gan Weidong, deputy director, said, this 74-year-old woman was right renal cell carcinoma patients, as well as hypertension, diabetes and other chronic systemic disease, poor heart function, and body fat, comprehensive variety of factors, She chose the RF treatment. The traditional surgical approach is open surgery, in patients with lower back or abdomen left more than 20 cm of wound, trauma significantly, recovery time is longer. The non-invasive radio frequency technique used was “Fire Attack” house of microwave theory and similar to that in the CT or B-accurate positioning, can transmit energy to a direct percutaneous needle, piercing the tumor center, through the release of the RF wave of the tumor, “heating” to 100 degrees Celsius, “burning” dead tumor cells. Small tumors generally “heat” 12 minutes, can be repeated if the tumor is large, “burning” 2-4 times, and in patients with body surface leaving only a needle.
