Oh, the Wonders of Zapping Prostates with Radiation!
Once upon a time, in the magical land of medical research, some very busy bees decided to figure out if blasting prostate cancer with a double whammy of external beam radiotherapy (EBRT) and brachytherapy (BT) was the bee’s knees. So, they dove into the depths of Ovid MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials, because who doesn’t love a good library dive from January 1, 2000, to June 7, 2022?
They were on the hunt for the holy grail of “benefits and harms” of EBRT-BT versus the solo act of EBRT or the classic cut-it-out approach (radical prostatectomy) with or without a post-op radiation encore. They wanted to know if this dynamic duo could keep the biochemical boogeyman at bay, avoid making new cancer friends (metastasis), and, you know, keep people alive and kicking.
After assessing the risk of bias (because who would ever be biased in research?) and performing some confounding acrobatics, they managed to include 73 studies in their systematic review. Most of these studies were like, “Let’s look back in time,” because they were retrospective, and only two were randomized controlled trials (RCTs), which are the gold standard, but who’s counting?
Turns out, EBRT-BT is like a biochemical bouncer, keeping progression-free survival in check better than EBRT alone. But when it comes to metastasis-free survival, cancer-specific survival, and overall survival, it’s a bit of a shrug—similar outcomes, folks. The meta-analysis of the two RCTs was like, “Here, have some numbers,” showing a hazard ratio that made EBRT-BT look pretty good for keeping biochemical progression at bay.
But wait, there’s a catch! If you like your urinary functions the way they are, brace yourself. EBRT-BT might just throw a wrench in the works, especially if you’re into the low-dose-rate flavor, with a 6.4-7% chance of severe late genitourinary toxicity. Yikes!
So, what’s the verdict? If you’ve got a prostate that’s playing host to some unfriendly cells and you’re cool with potentially trading in your smooth urinary experiences for a bit of extra biochemical control, EBRT-BT might just be your jam. But let’s not get too excited—the European Association of Urology is giving this recommendation with a wink and a nudge, because the evidence is as strong as a wet noodle.
In summary, more radiation seems to keep the cancer quiet for longer, but it’s a bit of a gamble with your pee-pee peace. And as for the big questions of life and death? The jury’s still out, folks.
