Kaohsiung Branch-Yung-Ching Proton Center

Proton Therapy is currently the most cutting-edge tumor radiation therapy in the world. Proton Therapy brings a lot less damage to the normal tissues around the focus and thus produces relatively less side effects. Yung-Ching Proton Center of Kaohsiung Chang Gung Memorial Hospital has introduced the newest proton therapy instrument to offer the best therapeutic approach for treating tumor. Compared with the traditional radiation therapy, proton therapy differs from the former in that the character of its proton beam releases only a small amount of energy when the proton passes through the tissues and releases a quantity of energy (which is called the Bragg peak) when reaching the depth of the tumor. As for the normal tissues behind the tumor, none radiation dose will be discharged. Yung-Ching proton and cancer center of Kaohsiung Chang Gung Memorial Hospital has introduced the equipment of proton therapy of the latest generation, adopting a proton beam as thin as brush stroke (pencil beam scanning) to scan the irradiated target. The approach allows the physician to irradiate the focus and evade the normal tissues by following exactly the shape of the tumor, so as to increase therapeutic effect and reduce side effect at the same time. This type of proton therapy is called “pencil beam scanning intensity-modulated proton radiotherapy”. So far, Taiwan Kaohsiung Chang Gung Memorial Hospital has established three proton treatment rooms and introduced comprehensively the state-of -the-art pencil beam scanning intensity-modulated proton radiotherapy.

Yung-Ching Proton Center offers the most advanced customized radiotherapeutic technologies such as pencil beam scanning intensity-modulated proton radiotherapy, respiratory gating radiotherapy, intensity-modulated radiation therapy, and stereotactic radiosurgery.

Yung-Ching Proton Center has introduced the world’s cutting-edge medical cyclotron to give the patients the most accurate treatment with fewer side effects. And the radiation beam focused on the target not only enables shorter treatment period and better therapeutic effect but also causes less harm to the tissues, allowing the patients to go shopping, to go to work, to attend school, and to maintain the quality of everyday life after the treatment.

Successful Cases / Success Rates

Kaohsiung Chang Gung Hospital Radiation Oncology is the predecessor of Yung-Ching Proton Center, and the unit has treated more than 60 thousand patients ever since the opening. The treatment success rate varies in accordance with the diversity of diseases the patients have caught in. The best one is the control rate of brain tumor control, which has reached up to 95%.

The image on the left shows the traditional intensity-modulated radiation therapy as the beam of radiation pierces through and brings much dosage into the brain and brainstem.

The image on the right indicates the one of proton therapy. Since the Bragg peak of proton beam and pencil scanning enable the dosage to focus on the tumor and carry out the irradiation by following the shape of the tumor, the volume of irradiated normal brain and brainstem becomes extremely small, raising control rate while reducing the side effects.

Q: What are the advantages of proton therapy?

Proton therapy differs from the conventional radiation therapy in that the character of its proton beam releases only a small amount of energy when the proton passes through the tissues and releases a quantity of energy (which is called the Bragg peak) when reaching the depth of the tumor. As for the normal tissues behind the tumor, none radiation dose will be discharged. Due to the insufficient width of a single Bragg peak, several should be combined together in order that the size of the tumor can be coated with the extension of Bragg peak (Spread-out of Bragg peak, SOBP). Since the adoption of proton radiation therapy can reduce the amount of radiation dose received by the normal tissues, it can be applied to the tumors grown close to vital organs or on patients who need to receive another radiation therapy after having already undertaken a radiation therapy.

 

Q: What is the difference between pencil beam scanning intensity-modulated proton radiotherapy and conventional proton therapy?

In the beginning when people try to develop proton therapy, they adopt scatter incorporated with compensator to design the depth of Bragg peak extension and use brass baffle block to cover the unwanted irradiated area. Since this kind of approach cannot be applied to treat complex-shaped tumors for that it is impossible to practice the treatment by following exactly the shape of the tumor, the dosage of radiation received by the normal tissues is relatively higher. In addition, the patients are required to pay a huge price for the design and making of compensator and brass baffle block. The new generation of proton therapy instrument has developed a novel proton irradiative approach. Instead of adopting scatter, it exploits a proton beam as thin as a pencil sketch to scan the desired irradiated  target. The approach allows the surgeon to irradiate the focus and evade the normal tissues by following exactly the shape of the tumor, so as to increase therapeutic effect and reduce side effect at the same time. This type of proton therapy is called “pencil beam scanning intensity-modulated proton radiotherapy”. Up to present, Taiwan Kaohsiung Chang Gung Memorial Hospital has established three proton treatment rooms and introduced comprehensively the state-of -the-art pencil beam scanning intensity-modulated proton radiotherapy in the hope of contributing the best therapeutic services.
