Oh, What a Surprise: Magnets Make Brain Surgery Better
Who would have thought that using intraoperative magnetic resonance imaging (iMRI) could actually help surgeons remove more of that pesky brain tumor and potentially keep patients kicking longer? It’s not like we’ve been using MRI for decades to peek inside the human body or anything. But, lo and behold, the wizards of science conducted a study (NCT01479686) to confirm this groundbreaking idea.
They split a bunch of patients into two groups: the high-tech iMRI squad (161 patients) and the old-school conventional neuronavigation crew (160 patients). The main event was to see who could achieve the elusive ‘gross total resection’ (GTR) – basically, the surgical equivalent of a home run.
And guess what? The iMRI group knocked it out of the park with an 83.85% GTR rate, while the control group lagged behind at a mere 50%. But wait, there’s more! The median progression-free survival (mPFS) was a whopping 65.12 months for the iMRI group, compared to a slightly less impressive 61.01 months for the others. High-grade glioma (HGG) patients in the iMRI group lived a bit longer without their tumors getting feisty again (19.32 vs. 13.34 months), and they even had a hint of better overall survival.
For those with HGGs in the ‘eloquent areas’ of the brain (you know, the parts that actually do important stuff), the iMRI group had a mPFS of 20.47 months and a median overall survival (mOS) of 33.58 months. The control group? Not so hot, with 12.21 months and 21.16 months, respectively.
And here’s a shocker: leaving less tumor behind (<1.0 cm3) seems to be a good thing. Who would’ve guessed? Those with tiny bits of residual tumor had better survival rates. As for the low-grade glioma (LGG) crowd, if you walked in with a tumor larger than 43.1 cm3 and left with more than 4.6 cm3, things weren’t looking too rosy.
CONCLUSIONS: In a twist that surprised absolutely no one, sticking an MRI machine in the operating room helps surgeons do a better job at tumor-ectomy. And, shockingly, the less tumor you leave behind, the better your chances of not dying. Science, folks. It’s wild.
