Spots Global Cancer Trial Database for The Composite Steep-pulse Treatment Apparatus Used in Prostate Cancer Ablation Therapy

Study Description

Brief Summary: This trial is studying the effects and safety in treating patients from five different centers with local prostate cancer, employing Composite Steep-pulse(High-frequency irreversible electroporation) Treatment Apparatus. This device could cause cell irreversible electroporation, which leading necrosis of tumor cells. It also has the ability to prevent nerve,vessel, urethral and capsule unnecessary injury beside the ablation area. Composite Steep-pulse Treatment Apparatus will be used in patients who pass inclusion/exclusion criteria. Safety, quality of life, and histopathological analysis of prostate speciem will be evaluated in each study patients.

Detailed Description: Background: Prostate cancer is the most common cancer in elderly males in western country. It is also a major health concern, especially in China with its greater proportion of elderly men in the general population. Currently, radical prostatectomy(RP) is the mainstream treatment for localized PCa to show a benefit for cancer-specific survival (CSS). However, the patient who underwent RP might suffer from the complication of erectile dysfunction or urinary incontinence. In 2004, a new method using steep pulses to treat tumor was appeared. It showed that steep pulses could bring about Irreversible Electroporation (IRE) of cell, leading tonecrosis of tumor cells. And it seemed to do no harms to the nerve and Vascular epithelial cell. The device of steep pulse had already been approved by FDA in 2011.However, this device of steep pulse has disadvantages like: (1)sever muscle contraction;(2)Urethral injury; (3)Capsule injury;(4)Nerve degeneration. This new device which is called Composite Steep-pulse(High-frequency irreversible electroporation) Treatment Apparatus, may have the potential to conquer these disadvantages. Purpose: 1. This study will assess the efficacy of Composite Steep-pulse(High-frequency irreversible electroporation) Treatment Apparatus in the treatment of PCa. 2. This study will assess the safety of Composite Steep-pulse(High-frequency irreversible electroporation) Treatment Apparatus in the treatment of PCa. Methods: 1. patients recruitment 2. transperineal maping prostate biopsy(\>20 needle) guided by transrectal ultrasound(TRUS). 3. Irreversible Electroporation of malignant Tumor Cell under Composite Steep-pulse Treatment for the patients with positive biopsy; 4. Some factors such as prostate MRI,the maping prostate biopsy(\>20 needle),the histopathological outcomes analysis ect. will be performed to evaluate the efficacy of the treatment. 5. Other factors such as the routine blood test, the routine urine test, the urinary continence ect. will be performed to evaluate the safety of the treatment.
