Particle Implantation
What is Particle Implantation?

Particle Implantation, also called Particle knife, is a brand-new minimally invasive treatment against deficiencies of the international medical surgery and radiotherapy nowadays. Energy of the rays and amount of the particles are determined by the character, size and location of the tumor. Under the guidance of imaging equipment, I125 seeds will be directly placed into the tumor or possible paths of metastatic tissues. These implanted particles will keep emitting γ-ray within the tumor, targeting to the cancer cells accurately, just as surgical excision do.

Particle Implantation VS Traditional Radiotherapy
Items of Comparison Particle Implantation Traditional Radiotherapy
Safety High safety High risk
Damage Degree Millimeter minimally invasive; only takes effect in the tumor and do less harm to normal issues; few toxic side effects and complications. Radioactive rays will do harm to surrounding normal issues when irradiating at the tumors, which will result in decrease of human immunologic function and causing some severe toxic side effects like nausea, vomiting, diarrhea and loss of appetite, etc.
Drug Concentration Small irradiation area, continuously aim to the tumor only, target oriented, high radiation dose (2-3 times higher than external radiotherapy); Large irradiation range, high energy rays go through the skin and tissues first, then reach to the tumor with small dose left;
Treatment Duration The duration of which lasts for 6 months, effectively reduces patient’s frequency to visit hospital for radiotherapy; External radiotherapy is generally carried on 5 times a week, so a course of treatment last generally 1-2 months;
Curative Effect The radiation of seeds to tumor last for 6 months, which ensures the cancer cells exposure to the rays evenly, effective to cancer in different stages, External radiotherapy is fractionated irradiation, only works to part of cancer cells;
Procedure of Particle Implantation
1. Make sure the amount of the particles and seeds implanting position
2. Localized the tumor by the guidance of imaging equipment after local anaesthesia
3. Placing implanted needle into the tumors accurately and inserting particles
4. Those particles will keep emitting γ-ray within the tumor to break up the DNA chain, resulting in the death of the tumor due to losing reproductive capacity.

Particle Implantation is being performed.

Targeted Users:
1. Untreated patients with primary tumor
2. Patients who do not want or are not suitable to take operation.
3. Patients who got poor efficacy or failed after taking traditional radiotherapy.
4. Patients need local dosage supplement due to inadequate dosage of radiotherapy.
5. Patients who suffer from residual tumors during the operation or resection margin with tumor nearby. (<0.5cm)
6. Patients cannot undergo operation again due to the recurrence of tumor
7. Inoperable patients with metastatic tumor lesions or postoperative solitary metastatic tumor
Applicable illnesses:

Lung cancer, prostate cancer, breast cancer, liver cancer, nasopharyngeal cancer, tongue cancer, parotid gland carcinoma, tonsil cancer and endometrial cancer, etc.
