2019 MAY 13 (NewsRx) -- By a News Reporter-Staff News Editor at NewsRx Drug Daily -- Data detailed on Oncology - Prostate Cancer have been presented. According to news originating from Columbia, Missouri, by NewsRx correspondents, research stated, “The objective of this research was to estimate the dose distribution delivered by radioactive gold nanoparticles (AuNPs or AuNPs) to the tumor inside the human prostate as well as to normal tissues surrounding the tumor using the Monte-Carlo N-Particle code (MCNP-6.1.1 code). Radioactive gold nanoparticles are emerging as promising agents for cancer therapy and are being investigated to treat prostate cancer in animals.”

Our news journalists obtained a quote from the research from the University of Missouri, “In order to use them as a new therapeutic modality to treat human prostate cancer, accurate radiation dosimetry simulations are required to estimate the energy deposition in the tumor and surrounding tissue and to establish the course of therapy for the patient. A simple geometrical model of a human prostate was used, and the dose deposited by AuNPs or AuNPs to the tumor within the prostate as well as to the healthy tissue surrounding the prostate was calculated using the MCNP code. Water and A-150 TEP phantoms were used to simulate the soft and tumor tissues. The results showed that the dose due to AuNPs or AuNPs, which are distributed homogenously in the tumor, had a maximal value in the tumor region and then rapidly decreased toward the prostate-tumor interface and surrounding organs. However, the dose deposited by Au is significantly higher than the dose deposited by Au in the tumor region as well as normal tissues.”

According to the news editors, the research concluded: “According to the MCNP results, AuNPs are a promising modality to treat prostate cancer and other cancers and AuNPs could be used for imaging purposes.”
