When you hear "radiation therapy," your mind probably jumps straight to cancer treatment. And you're not wrong – for nearly a century, radiation has been a vital weapon in the fight against various malignancies. But what if we told you this powerful tool has another, lesser-known talent?
It turns out, radiation's ability to precisely target and affect rapidly dividing cells isn't just useful for cancer. It can also be a game-changer for certain non-cancerous conditions!
Low-dose radiation therapy (LDRT) shows great promise for a surprising range of benign conditions. These often fall into a few categories:
Historically, LDRT was used for these benign conditions. However, over the past few decades, other treatments like steroid injections gained popularity. But now, LDRT is experiencing an exciting resurgence, especially for musculoskeletal issues. Why the renewed interest? Because it's effective and has a remarkably minimal side effect profile!
It’s crucial to understand that the radiation doses used in LDRT are significantly lower than those used for cancer treatment. This means the side effects are generally mild and temporary, such as:
Let's dive into some specific conditions where LDRT is showing incredible potential:
Tens of millions of Americans grapple with osteoarthritis, the most common form of arthritis. It's often the result of lifelong "wear and tear" on our large joints, leading to the breakdown of bone and cartilage. This breakdown is driven by various inflammatory processes.
LDRT steps in by modulating these immune-mediated pathways, essentially creating an anti-inflammatory environment. Studies have shown LDRT can be effective for osteoarthritis in various joints (knees, hips, hands, feet/ankles), with reported success rates of 60%-80%.
LDRT is typically recommended for patients in the medium to late stages of the disease. Early cases often respond well to conservative care, while end-stage osteoarthritis usually benefits most from surgery. A standard LDRT course for osteoarthritis typically involves 6 brief radiation sessions over 2-3 weeks.
If you've ever dealt with plantar fasciitis (PF), you know that debilitating heel pain. It's caused by inflammation and degeneration of the thick band of tissue connecting your heel to your toes. Chronic damage from activities, exacerbated by factors like obesity, running, prolonged standing, and improper footwear, all contribute to this frustrating condition.
While many cases improve with conservative treatments, persistent PF can be a real challenge. This is where LDRT holds great promise! Its ability to decrease tissue inflammation and promote healing offers a new avenue for relief. Multiple studies have demonstrated the efficacy of LDRT for plantar fasciitis with minimal side effects.
Dupuytren’s Disease (DD) is a common, often unpredictable condition where the fascia (a layer of tissue) in the palms of the hands thickens. In its early stages, nodules and cords form, which can progress to fixed contractures in the later stages, making it difficult to fully straighten your fingers.
Historically, surgery (fasciectomy) and other invasive procedures (like enzyme injections) were the primary options, but only for advanced stages. LDRT has emerged as an exciting early intervention to potentially halt the progression of DD, potentially reducing the risk of needing surgery.
A standard LDRT course for Dupuytren’s Disease involves five treatment sessions over one week, followed by a booster course after a 10-12 week gap. Again, side effects are mild, typically just temporary redness and soreness, with a very small (0.1%) risk of skin cancer.
If you're dealing with one of these benign conditions and other treatments haven't provided the relief you need, LDRT could be an option worth exploring. Talk to your doctor or a radiation oncologist to discuss if this innovative and effective treatment could be the answer to your pain and limitations.
CHI Health currently offers LDRT at CHI Health St. Elizabeth in Lincoln, NE and at CHI Health St. Francis in Grand Island, NE.
