Local cancer patients receive access to world-class treatment for prostate cancer.

Prostate cancer is the most commonly diagnosed cancer (apart from skin cancers) in New Zealand men. Each year more than 4000 men are diagnosed with prostate cancer across New Zealand. Bowen Icon Cancer Centre now offers faster, more effective treatment for prostate cancer patients with the introduction of linear accelerator-based stereotactic ablative radiation therapy.

Stereotactic ablative radiation therapy reduces the overall treatment time, delivers high doses of radiation in less than 15 minutes, and monitors the patient’s prostate motion using small gold markers to ensure the radiation is delivered with absolute accuracy.

Invercargill local John Patrick is the first prostate cancer patient treated with stereotactic ablative radiation therapy at Bowen Icon Cancer Centre. The 62-year-old was diagnosed with prostate cancer in February this year.

“It started with a urinary retention problem in 2020. I was treated by a urologist who diagnosed a stretched bladder and slightly restricted flow through the prostate. Following a period of unsuccessful self-catheterisation, the urologist performed a TURPS procedure, and the urine retention problem was reduced. At the same time, a PSA (Prostate Specific Antigen) test was done, which showed my PSA was high. My GP started to monitor the PSA level, which started to climb higher and higher. The decision was made to do a biopsy, and cancer was confirmed. The Gleason score was relatively low at 3+3, and the decision was made to monitor the prostate with regular MRI scans. However, the first scan came back with a PI Rads level 5 score, which normally suggests quite an aggressive tumour. I was advised to undergo a radical prostatectomy, which I wasn’t entirely comfortable with. A family member suggested I speak to an oncologist, so I went back to see my GP, and he referred me to Dr David Anderson. Dr Anderson explained the radiation options available to me, and it gave me different avenues to try. Meeting Dr Anderson and the team at Icon was a godsend,” John said.

John was referred to Bowen Icon Cancer Centre and underwent five sessions of stereotactic ablative radiation therapy over ten days. John, who started a new job at the same time as his cancer diagnosis, said the reduced treatment time offered by the new treatment was a vital factor in his decision.

John is now encouraging his male friends, family members, and colleagues to get tested and, in the case of a prostate cancer diagnosis, to thoroughly research treatment options.

Bowen Icon Cancer Centre Radiation Oncologist Dr Han Kim said the new treatment is a big win for New Zealand prostate cancer patients.

“This technology allows a high dose of radiation to be delivered to the tumour very precisely, without compromising surrounding healthy organs due to the ability to treat with sub-millimetre accuracy. Through larger daily doses of radiation delivered to patients with SABR, treatments can be completed within five to seven treatments spanning over ten to fourteen days. A standard course of prostate cancer radiation therapy can involve four to eight weeks of daily visits. This makes stereotactic ablative radiation therapy considerably more convenient for patients, minimising the impact and burden of time and travel, particularly for those who live some distance from a radiation therapy centre,” Dr Kim said.
