Prof.Zhen Yanli is a distinguished expert of minimally invasive surgery in China and chief specialist of minimally invasive targeted therapy in St.Stamford Modern Cancer Hospital Guangzhou. He has been engaged in research and clinical interventional therapy for over 30 years. He’s expert in percutaneous selective arterial infusion chemotherapy for malignant tumor and percutaneous selective arterial embolization. He is also proficient in precise minimally invasive surgery, which is advocated in 21 century and requires patience, devotion and especially high expertise.

1. What is Microcatheter Superselection?

Microcatheter Superselection is a more precise and more advanced version of interventional therapy. During the treatment, Microcatheter is respectively placed in each supplying artery for tumors, through which anticancer drugs is accurately injected into the tumor. The procedure guarantees high concentration of drugs, ensures the entire tumor to be completely covered and precise embolization of supplying artery to be performed. Comparing to traditional interventional therapy, microcatheter superselection features advantages of killing tumor more accurately and completely. So it realizes better efficacy and radically poison and starve the tumor to necrosis.

2.Disadvantages of traditional interventional therapy

Due to the backward equipment or limited skills of physician, the catheter fails to reach tortuous and tiny blood vessels and injects or embolizes to upper branches of supplying artery for tumor, instead, to normal visceral organs. As a result, patient would suffer side effect and normal functions of visceral organs would be badly affected.

3. Advantages of Microcatheter Superselection

(1) High accuracy: anticancer drugs respectively cover each supplying artery of tumors;

(2) High efficacy: concentration of anticancer drugs is 16 times higher than that of intravenous chemotherapy;

(3) High safety: little damage to adjacent visceral organs and fewer complications;

(4) High security: low chance of recurrence and metastasis.

4. Application of Microcatheter Superselection

Microcatheter Superselection can be widely applied to solid tumors in organs such as liver, pancreas, lung, kidney, prostate, breast and other female organs.

5. Surgical Case

According to strict procedures and accurate operation, physician carefully performs injection and embolism in patient’s applying artery for liver, step by step, layer by layer. The angiography indicates that the tumor has been stained and has disappeared. That means the tumor has been completely covered by anticancer drugs. All left is just normal hepatic blood vessels.

How We Treat Cancer?

Interventional Therapy

Interventional Therapy is a new substitute of traditional chemotherapy, which means that a physician introduces instruments such as needles or catheters (long, thin tubes) into the body through tiny(1-2 mm) incisions in the skin. The instruments are then guided by an imaging technique called fluoroscopy to the cancer tumor. In this way, the physician can deliver cancer medicine directly to the tumor.more info

Cryotherapy Therapy

Cryotherapy Therapy, also known as “Argon-Helium Knife Cryotherapy”, is a new substitute of traditional physical therapy. Practically speaking it is “extreme cold + extreme heat” cancer treatment. Generally, a minimum of 10-15 minutes is required to achieve an extreme analgesic (pain relieving) effect while lowering the temperature to the injured area, thus reducing the metabolic rate and swelling associated with tissue injury.more info

Particle Knife

Particle Knife is a new substitute of traditional radiation therapy. With the help of computer Treatment Planning System (TPS), radioactive particles will be implanted into tumors. The particles which release γ-rays can continuously kill tumor and cause destruction targeting tumor cells. With time, the radiation amount would accumulate to be large enough to destroy the DNA double strands of tumor cells.more info
