The shopping website is full of smart watches, sports bracelets and Bluetooth watches, and a variety of "wearable devices" are unfortunate. Some even have medical health functions, measure blood pressure, heart rate and blood sugar, monitor around the clock and warn when the value is abnormal! At present, more scientists have developed wearable devices (portable, but larger) to emit electromagnetic waves into the brain of brain cancer patients, hoping to inhibit the growth of brain tumor cells and help patients fight cancer cells.
Tumors continue to grow because of the unrestricted proliferation of cancer cells. When the cells undergo cell division, a filamentous protein structure (spindle) is produced in the cells, and the replicated chromosomes are pulled to the ends of the cells on average, so that the newly formed cells can obtain the intact DNA of the mother cells . The spindle has an electrode polarity, and one end is negatively charged and the other end is positively charged, so it is easily affected by the external electric field to change the axial direction. When the spindle is forced to change direction, the structure cannot maintain normal and collapse, and the chromosomes cannot be properly separated, causing new cells to die.
Based on the above principles, NovoCure Company of the United States has developed a portable brain cancer treatment wearable device Optune, which is worn on the head (the patient must shave the hair) to emit low intensity (1~2V/cm) and medium frequency (100~200 thousand). The alternating electric field of He) interferes with the cell division of cancer cells to treat brain cancer (Note 1).
Recently led by Professor Roger Stupp, a neuro-oncologist at the Northwestern University School of Medicine, the results of a clinical trial of Optune in the treatment of brain cancer patients. A total of 695 adult brain cancer patients were enrolled in the trial, and each subject was randomly assigned to the current chemotherapy group, or to chemotherapy plus the Optune adjuvant treatment group. The results showed that adjuvant treatment with Optune significantly increased patient survival (Note 2).
Dr. George Demetri, an oncologist at the Dana-Farber Cancer Institute (Note 3), said: "Although Optune's treatment is limited, some types of brain cancer patients often cannot survive after diagnosis. One year, so any treatment that will extend the life of the patient is worth supporting."
Water can also be used to carry a boat, and the electromagnetic waves that everyone can smell can be used to treat cancer. Scientists are testing the effect of attaching electrodes to the abdomen or chest of patients to treat pancreatic cancer, ovarian cancer, and lung cancer. I believe there will be more exciting conclusions in the follow-up.
The current cost of treating patients with Optune is still very expensive, costing about $20,000 per month. In addition, the Optune is not small, almost occupying a backpack space. However, with the rapid development of technology, just like the development of mobile phones, I believe that in the near future, operators will be able to introduce portable electromagnetic wave cancer treatment equipment that is cheaper and smaller.
Note 1: It takes more than 18 hours to wear in one day, but it can be used normally. When it emits electromagnetic waves, it only feels that the scalp is slightly hot, and there is no feeling of electricity.
Note 2: The 2-year survival rate of the chemotherapy-only group was 31%, and the 5-year survival rate was 5%. The chemotherapy-assisted patients treated with Optune had a 2-year survival rate of 43% and a 5-year survival rate of 13%.
Note 3: Dana Farber Cancer Institute was established in 1947. It is a cancer specialist affiliated hospital of Harvard University, and the US government has designated a cancer treatment center.
