Cancer and particularly prostate cancer has been one of the biggest impediments to a healthy life for many men in the world today. In recent years, there has been renewed development in its treatment. One of such advancements is Radium 223, a radioactive compound created for the express purpose of treating cancer cells that have spread to the bones. It has been mainly applied in patients with hormone-refractory metastatic prostate cancer which spreads to the bones. But could Radium-223 also be used during the early stages of prostate cancer?
As being related to the COVID-19, one aspect that has emerged in focus over the recent past is on its impact on the immune system. In this blog, we consider what role could Radium223 might play in immune changes and how this might change treatment for early stage prostate cancer.
Radium 223: A Brief Overview
Radium 223 is a natural radioactive isotope that emits alpha particle. These particles have a short range, and therefore, cytotoxic in cancerous tissues but do not affect the normal tissues. In essence, it imitates calcium and becomes incorporated in areas of high bone turnover, areas that cancer is targeting in the bone. This localized radiation harms cancer cells by affecting their DNA to the extent that those cells die with very little harm done to the most of the healthy tissues in the region. Radium 223 has been received in the last few years as effective when used in treatment of small parts of bones affected by advanced prostate cancer. Notwithstanding, increasing evidence indicates that, as compared to patients with advanced disease, this isotope might have a similarly broad therapeutic application for individuals with earlier stages of the disease.
The advantage of radium 223 is Its selectivity on bone metastases gives Radium-223 an edge compared to other bone metastases treatments for patients with advanced prostate cancer.
The Study: Key Findings
A recent study that appeared in the Nature Communications journal focused on radium 223 and it role in prostate cancer that is at an early stage. Scientists used one dose of radium 223 to treating a group of patients with low-risk prostate cancer and then evaluate their outcomes at different later times. The researchers discovered that the treatment not only inhibited tumor growth but also had a stimulation of activities of the immune cells within the tumor microenvironment. Accordingly, a immune response was related to reduced rates of cancer reoccurrence.
How Radium 223 Works
Radium 223 is designed to reduce bone metastases by emitting high-energy alpha particles right at the site where cancerous cells form in the bones. The radiation being used is highly localized so it only goes a short distance into the body and thus has minimal effect to neighboring healthy tissues. This approach of targeting alleviates bone pain and delays the onset of bone problems which many patients PRCA experience.
Scientists understand it targeted in damaging cancer cells in bones, but they have recently shifted their attention to how it influences the immune system as well. This new approach provides potential to employing the therapy in initial stages of prostate cancer.
Radium 223 and Immune Changes: What We Know
Some studies that have been done recently indicated that Radium 223 might have immunological effects. This means that it could help the immune faster and more effectively identify cancer cell and destroy them. Immunotherapy, developed to help the body’s immune system fight cancer, has remained an area of interest in oncology. Could Radium-223 play a part in this already burgeoning area?
Some of evidence show that radiation can stimulate immune reactions in addition to killing cancer cells and of making cancer cells visible to immune system. Essentially, what is being seen is known as abscopal effect, where radiation to one place in the body can trigger immune response in the whole body. Though it’s rare, Radium223’s role in inducing such responses is still being studied.
Could Radium 223 Change Early Prostate Cancer Treatment?
So far, Radium 223 has primarily been employed for the treatment of castration-resistant prostate cancer that has resulted in metastases to the bones. While side effects from its use in the hormone-delaying role are still apparent, with early indications of its ability to modulate the immune system, researchers are investigating whether it could also be effective for early-stage prostate cancer.
If Radium 223 increases immunological reactions, it can be combined with immunotherapy at earlier stages of prostate cancer which may display better results in preventing the cancer from spreading to the bones. This would a significant advancement in the ways of combating prostate cancer.
The Benefits of Using Radium 223 in Early Prostate Cancer
The results of the evaluation indicate that radium 223 can be useful in several ways for patients with early-stage prostate cancer. First, it may help discourage cancer’s return even in patients whose initial cancer is deemed low-risk. Second, radium-223 may be preferable to surgery of the cancerous organ or radiation therapy that often has severe side effects. Last, but not the least, the ability of radium223 to stimulate immunity may help avoid metastatic disease.
- Targeted Radiation: Because Radium 223 produces alpha particles, the radiation is very limited within the cancerous tissues and minimal on normal tissues.
- Potential Immune Activation: The result showing Radium 223 has an affect on the immune system, further studies, if done, might show that Radium 223 can be combined with treatments of early-stage cancer.
- Fewer Side Effects: It is also essential to note that Radium-223 because it selectively targets bone metastases has relatively few systematic side effects as opposed to traditional radiation therapies.
Possible Drawbacks
- Limited Application in Non-Bone Metastatic Cases: At this time, Radium 223 works best only for prostate cancer that have already metastasized to the bones.
- High Costs: Radiopharmaceuticals such as Radium-223 can be costly, thus early stage treatments may not be cost effective unless used in combination with other treatment approaches.
- Further Research Needed: Radium223 still has not shown the full immune-modulating potential, and new clinical trials should be launched.
The Future of Radium 223 in Prostate Cancer Treatment
Radium 223 has already been approved as an effective option for management of metastatic castration-resistant prostate cancer (mCRPC) specifically, patients with metastases to the bone. Building on these immunomodulatory findings, researchers may soon introduce it at even higher stages of the disease. To date, directing Radium 223 together with immunotherapy can be characterized as a unique opportunity to additionally strengthen the protection of patients with prostate cancer, increase the rates of survival, and improve their quality of life.
Nevertheless, much more extensive studies are needed to fully launch Radium-223 into the position of the future of cancer therapy, including the stages of cancer in remission. It has high cost, narrow applicability to non-bone metastatic cases, and lack of additional clinical trials—problems that must be solved..
Conclusion
Radiium 223 and immune changes study in the early stage of prostate cancer explores a ray of hope for patients with this difficult disease. Further studies are called for to determine the overall advantages or drawbacks of this remedy, however, the results imply that radium223 can make a good prostate cancer therapy and decrease the risk of cancer progression in the early stages.
Frequently Asked Questions
