For the first time ever in the Southern hemisphere, two New Zealand patients have received a modified and new form of brachytherapy, a treatment for prostate cancer.

The traditional treatment method involves the permanent implanting of small radioactive "seeds" directly into the prostate gland. The measure has been practiced for about 20 years.

The "ThinStrand" technology, which is the new form of the general treatment for prostate cancer, works by utilizing smaller needles in order to implant smaller seeds. Initial studies and researches carried out across the US have revealed that the new procedure results is lesser bruising at the area of implantation, and additionally, there is less pain involved.

Also, the studies revealed that there was an improved higher radiation dose in the prostate, which adds to the benefits.

"The thinner needles make the procedure even less invasive and this is a significant advantage for patients. It is possible that the thinner needles will cause less swelling in the prostate and there is a study in Seattle looking at whether the thinner needles will reduce the chance of urinary symptoms and impotence", shared Dr. John Matthews.

The new treatment method was successfully administered last week in Auckland, on patients housed at the Southern Cross Brightside Hospital by oncologist, Dr John Matthews, and urologist Derek Rothwell.
