Three-dimensional conformal radiation therapy is the use of modern imaging technology, computer three-dimensional image reconstruction technique, three-dimensional stereotactic radiosurgery physical means to treat cancer. This method has the target area of high-dose gradient dose outside the target area and a large dose distribution advantages to positioning accuracy, concentrated doses can well protect the surrounding normal tissue, has been widely used in clinical. Brain metastases have a clear border, mostly round, early reaction, and other characteristics of the organization to become three-dimensional conformal radiotherapy is more desirable target. But simply to accept the three-dimensional conformal radiotherapy in patients with intracranial relapse could be higher than the whole brain irradiation of patients. This is the result of three-dimensional conformal radiation therapy only for a clearFocus on the potential brain metastases is no treatment. Whole-brain radiation dose limit by raising them in tumor control rate, to extend the period of survival of smaller role, but the new focus on reducing the incidence of intracranial meaningful [7]. Clinical studies have shown that [8-10], the whole brain irradiation using local radiotherapy boost in improving the rate of tumor control and reduce local recurrence and new intracranial tumors occur to improve the patient's symptoms and signs, and KPS score to enhance and prolong the survival period of excellent In whole-brain radiation alone. The results of this study show that local control rate of 97%, neurological symptoms improved 40.6%, KPS to improve the score was 100%.

Three-dimensional conformal radiotherapy is using modern imaging technology, and computer image reconstruction technique, a three-dimensional orientation means of treating cancer radiotherapy physics. This method has high dose and target area target area dose of the dose distribution gradient, its advantages, precise positioning, dose could well surrounding normal tissues, has been widely applied in practice. Brain tumor metastasis has borders and a round, characteristics and early reaction organization as three-dimensional conformal radiotherapy ideal target. But simply accept three-dimensional conformal radiotherapy patients relapse than all the opportunity in the brain. This is because only with three-dimensional conformal radiotherapy of tumor clear, intracranial potential metastases and without treatment. The whole brain radiation dose limit by the tumor control bureau in improving and lengthened surial in small, but the effect of reducing the lesion occurred in new [7] meaningful. Clinical studies show that [8-10], the brain by local radiotherapy irradiation after tumor in pushing drugs, reduce to improve local recurrence and intracranial newborn tumors, improve the patient's symptoms and signs, improve KPS rating, lengthened surial in whole brain better exposure. The results showed that inning to 97%, control and neurological symptoms improved obviously 40.6% KPS rating increase of 100%.这样最好！
