The Novel Concept and Treatments for Cancer

"Seed Knife" Therapy

"Seed-knife" is a brachytherapy with implantation of radioactive seeds. The 125Iodine seed which is often used has a half -life of 59 days and releases short-course of gammaray. The seeds implanted into cancerous masses and nearby tissue radiate targeted cells and ultimately destroy cancer.
According to images offered by ultrasound, CT or MRI, using computational optimization techniques, a three-dimensional conformal treatment planning is made for making dose calculation. Then the number and location of seeds implanted is calculated.
Seed implantation is often performed percutaneously under guidance of ultrasound or CT, as well as by direct viewing during the operation.

Advantages

Seed therapy is a local radical ablation, hence it will not harm the whole body

The seed can neither be absorbed by body nor excreted to out of it. Therefore it is not harmful to surrounding people and environment
There are no major side effects which are developed in traditional chemo/radiotherapy
Seed implantation can be performed percutaneously and is a miniinvasive modality

Indication

As a primary or supplementary modality, seed implantation can be used for: prostate cancer, tumors of soft tissue (sarcoma), brain cancer (glioma), breast cancer,pancreatic cancer,liver cancer,tongue cancer,oral cancer, pharyngeal cancer, nasopharyngeal cancer, cervical cancer, ovary cancer, thyroid cancer, metastatic lymph nodes.
The technique is for eradication of unresectable or residue lesions during or after operation, as well as for prevention of cancer recurrence.
There is a synergistic effect of a combination of seed implantation with cryosurgery
