New combination therapy for brain tumors: photon knife + targeted therapy

Brain tumors threaten life

A variety of intracranial tumors are called brain tumors collectively. In recent years, brain tumors’ incidence has showed a rising trend. Intracranial tumors account for about 5% of systemic tumors and 70% of childhood tumors, and the probability of brain metastasis from other malignancies is 20% -30%. During the formation of intracranial tumor in the brain, the tumor will continue to grow, resulting in invasive growth. Whether it is benign or malignant, brain tumor will cause increased intracranial pressure, oppress brain tissue and damage central nervous system, and thus threaten life.

Although the disease is serious, patients should not worry about it too much, as there are many useful methods to treat brain tumors, like surgery, chemotherapy, radiation therapy, gamma knife, photon knife, interventional therapy, etc. Most brain tumor patients may choose surgery, but surgery itself is a kind of trauma, as brain nerve tissue is so complex that surgery may meet great risk and cause side effects. Most of tumors cannot be clean-cut, if there is still residual tumor or tumor cells, postoperative tumor re-growth or recurrence will happen. The mean survival period for postoperative malignant brain tumor patients is less than a year. Most brain tumor cells are not sensitive to radiotherapy or chemotherapy, and a few of sensitive patients may also experience normal cell damage during treatment.

Original comprehensive therapy effectively treats brain tumors

Single use of any technique cannot achieve an ideal state for brain tumor patients. Treatment principle of Modern Cancer Hospital Guangzhou is to choose the best combination therapy based on patients’ condition, as there are so many technologies and medicines, how can we choose? After many years of clinical experience accumulation and research of therapeutic methods, Modern Cancer Hospital Guangzhou has finally found that if combined with targeted therapy and further with TCM immunotherapy, photon knife can play a good role in controlling the condition of brain tumor patients. This combination therapy has a good therapeutic effect to primary brain tumors and secondary brain tumors.

Photon knife combined with targeted drug therapy

The appearance of Gamma Knife and photo knife technology is a considerable progress in the development history of brain tumor treatment. Both technologies are angle positioning through computer to carry out irradiation and kill tumor. The difference is that the energy contained in gamma knife is larger, which is suitable for a one-time treatment and more suitable for patients with brain tumors less 3 cm. However the side effects caused by Gamma knife on the human body are also relatively stronger. Photon knife contains less energy and can be used repeatedly to gradually kill tumors. Because energy is less, side effects on the human body are relatively reduced, and thus patients can have a higher degree of tolerance.

Modern Cancer Hospital Guangzhou has introduced world-advanced conformal radiotherapy system combined with large medical equipment for cancer radiotherapy - linear accelerator, which makes photon knife more conformal and precise in the clinical radiotherapy treatment. Conformal technology is a kind of high precision conformal radiotherapy, as it applies computer calculations to adjust irradiation lines, so that the tumor can be completely consistent with radiation eye regardless of the shapes. Faced with the irregular shape of brain tumors, skillful and experienced doctors carry out precise positioning through the implementation of conformal radiotherapy techniques, and then kill brain cancer cells while fully maximize the protection of other brain normal tissues.

Although targeted therapy of Modern Cancer Hospital Guangzhou is a kind of chemotherapy, chemotherapy can cause 90% side effects while targeted therapy only 10%. Because targeted drugs only kill cancer cells, this therapy generates little damage to normal tissue, won’t cause sharp drop to white blood cells or further lower down patients’ immunity function, what’s more, the side effects like nausea, vomiting, hair loss, anorexia, etc. are small. After several studies and clinical experiences, the targeted drugs chosen by Modern Cancer Hospital Guangzhou can directly and accurately work on brain tumor cells, if combined with photo knife technology, the therapeutic effect can be better. Besides, if traditional Chinese medicines can be prescribed as per patients’ individual condition, immune ability can be better restored and the living environment for cancer cells can also be collapsed to prevent further deterioration or even make them normal.

Experts remind that the sizes, quantities and locations of brain tumors have a great impact on the treatment effect, if it is a single brain tumor less than 3 centimeters, it may get a good therapeutic effect. Meanwhile, doctors shall design individualized treatment program for different patients as per their specific condition, as not all types of brain tumors are suitable for one certain combination therapy.

Modern Cancer Hospital Guangzhou uses a variety of combination therapy methods for improving the health of patients. Indonesian patient Mr. Mo, 58 years old, unfortunately suffers from lung cancer with brain metastasis. He came to Modern Cancer Hospital Guangzhou in Nov. 2011, and after comprehensive tests, the expert team chose cryotherapy and interventional chemotherapy for lung cancer, and photon knife combined with targeted therapy for metastasized brain tumor. After several courses, Mr. Mo’s spiritual condition greatly improved, so were his diet, sleep quality, bowel movement, weight gain, in a word, his condition had got great improvement. Besides Mr. Mo, there were many other similar successful patient cases, like another Indonesian patient Ms. Chen with lung cancer with brain metastasis, Vietnamese patients Mr. Tao with glioma and Ms. Guo with poorly differentiated right lung adenocarcinoma with both lungs metastases, brain metastases, multiple bone metastases, etc. can prove that comprehensive treatment really had its unique characteristics.
