This article is a very brief overview of two new treatment options that are showing enhanced life-expectancy over that of standard treatment alone.
Malignant Pleural Mesothelioma (MPM) is the most common type of mesothelioma, with past asbestos exposure representing the major risk factor. While the search for new therapies that target the genes and processes driving MPM has been slow, two new approaches are showing significant improvements over standard treatment in clinical trials. Best of all, these treatments are immediately available to cancer patients.
Before we discuss these enhanced treatment options, we’ll first briefly explore two key aspects of MPM progression
You’ve likely heard of angiogenesis. It’s the physiological process that tumours use to recruit new blood vessels in order to sustain their continual growth. They do this by manipulating the over-expression of genes that initiate and direct the growth of new, leaky blood vessels from existing ones. This new supply of blood not only allows the tumour to grow, but also provides a mechanism for the tumour cells to metastasize (travel through the body).
The process of angiogenesis is governed by its own unique combination of genes, separate from those involved in the normal formation of new blood vessels (a process known as vasculogenesis). This, it turns out, provides us with an opportunity for successful treatment through the targeting of these unique gene combinations.
One of the most specific and critical regulators of angiogenesis is the family of vascular endothelial growth factors (VEGFs), which regulate endothelial proliferation (the formation of new blood vessels), blood vessel permeability, and survival. In MPM, over-expression of VEGF is common and correlates with lower remission rates and reduced overall patient survival.
Clearly, effectively targeting VEGFs would result in limiting the blood supply to tumours thus successfully prohibiting their growth. And that’s just what we are seeing in current clinical trials. (More on that in a bit.)
A significant development in MPM treatment involves studies that focus on manipulating the processes of gene regulation, commonly referred to as epigenetic regulation. In MPM, tumour suppressor genes (the genes that, when functioning properly, naturally prohibit the growth of tumour cells) are silenced due to three key forms of epigenetic regulation:
In MPM, the over-expression of HDACs coupled with the inhibition of HATs is considered a key process that leads to disease progression. The over-expression of DNMTs occurs in most cancers.
The benefit of targeting epigenetic processes is that they are reversible.
The continued development and incorporation of these new drugs as part of standard treatment will undoubtedly be realized over the next few years. In the meantime, there are some very simple and effective natural measures that you can take immediately that will directly and powerfully influence the growth of cancer.
While clinical trials provide the basis for current molecular-targeted therapies, plant phytochemicals (aka nutraceuticals) provide an exciting option as an additional means of gene regulation.
Science has identified the following nutraceuticals as having a significant effect in slowing the mechanisms involved in MPM progression. Thus it is imperative, as part of your treatment protocol, that you ensure these substances are a part of your daily diet in the appropriate combinations.
The following section is a list of nutraceuticals that have been shown to directly affect epigenetic regulation and angiogenesis in various cancers.
There are many molecular pathways and genes involved in MPM; we have explored just a few above. However, including a daily diet of the nutraceuticals listed above will go a long way to improve your statistical chances for remission and disease prevention, as these nutraceuticals are revealing themselves to be significant in the treatment and prevention of many forms of cancer.
Given the success of current clinical trials being conducted using molecular-targeted therapies, this is also an important avenue to consider as an adjunct to standard treatment. Many clinical trials can be accessed from your hometown through your current treatment specialist, after a brief registration and testing process.
Please remember that it’s essential to talk with your doctor before considering any changes to your diet. While these nutraceuticals typically enhance any standard therapy, they can interfere with prescription drugs.
