The Evolution of Immunotherapy: A Game-Changer in Cancer Treatment
Written on
Chapter 1: The Remarkable Journey of Immunotherapy
Immunotherapy has emerged as a significant treatment modality for various cancers, and it’s a path I have personally experienced with great success. Despite being relatively unknown to many, the roots of immunotherapy trace back to 1891, when William B. Coley first explored this innovative approach. My initial encounter with cancer occurred 18 years ago, and I stumbled upon Coley's pioneering work, which inspired me to seek out alternative therapies.
Coley's method involved injecting patients with bacteria to induce fever, a concept I adapted by opting for sauna therapy instead. Research from Scandinavia suggests that heat therapy may serve as a preventive measure against cancer, prompting firefighters in Madison to utilize sauna treatments for this purpose. Coley’s original approach did not include saunas; rather, he injected streptococcal bacteria to stimulate the immune response, leading to tumor reduction. This marked the initial instance of immunotherapy's application in oncology.
As the head of the Bone Tumor Service at Memorial Hospital in New York, Coley treated over 1,000 cancer patients with what became known as Coley’s Toxins. Despite achieving remarkable outcomes, he faced significant criticism from his peers, a familiar pattern where groundbreaking medical advances take years, if not decades, to gain acceptance. Historical examples, such as the reluctance to heed Dr. Semmelweis's findings on maternal deaths due to sepsis, illustrate this phenomenon.
Sadly, Coley's Toxins, which were less harmful than contemporary chemotherapy and radiation, fell out of favor. However, the core principles of his work have been revitalized in recent years, earning Coley the title of "Father of Immunotherapy."
Section 1.1: Understanding How Immunotherapy Works
Immunotherapy leverages the body’s immune system to combat cancer, much like Coley's original approach. Modern techniques stimulate natural defenses and utilize lab-produced substances to enhance or restore immune responses. However, it’s important to note that not all cancers or patients respond to this treatment.
In my case, the results have been nothing short of miraculous. Instead of facing a grim prognosis of just a few weeks or months, my oncologist recently informed me that my response to immunotherapy suggests I might have years ahead of me. While the cost of treatment remains high, it is hopeful that prices will decrease over time.
Subsection 1.1.1: The Immune System's Role in Cancer
From a faith-based perspective, we are “fearfully and wonderfully made” (Psalm 139:14), but from a scientific standpoint, our bodies are marvels of evolution. Our immune system is equipped with cells and substances designed to fend off infections and diseases, including cancer. Yet, cancer cells often evade detection because they originate from normal cells, making it challenging for the immune system to identify them as threats.
White blood cells typically target foreign invaders, but cancer cells can masquerade as normal tissue, complicating the immune response. Furthermore, some cancer cells develop mechanisms to resist immune attacks. Immunotherapy addresses these challenges by enhancing the immune system's ability to recognize and destroy malignant cells.
Section 1.2: Different Forms of Immunotherapy
While there are various types of immunotherapy, this article focuses on the specific treatment I am undergoing. My regimen involves monoclonal antibodies, synthetic versions of the proteins produced by the immune system. These targeted therapies are designed to attack specific components of cancer cells.
The first monoclonal antibody, Rituximab, was approved for non-Hodgkin lymphoma in 1997, followed by Alemtuzumab for chronic lymphocytic leukemia in 2001. When I was diagnosed with cancer in 2004, immunotherapy was not widely available. A friend had to travel to Houston for treatment options that included immunotherapy, which was not offered in Austin or Dallas at that time.
The drug I am currently taking, Pembrolizumab, became available in 2014 and has only recently been accessible in my area. I was proactive in suggesting immunotherapy to my oncologist, who initially planned to offer standard chemotherapy.
Chapter 2: Immunotherapy vs. Chemotherapy
In contrast to chemotherapy, which directly targets cancer cells, immunotherapy offers a more varied response among patients. While chemotherapy results in immediate tumor shrinkage, immunotherapy may not yield immediate results and could even lead to initial tumor growth. However, when effective, immunotherapy often comes with significantly fewer side effects.
Chemotherapy attacks all rapidly dividing cells, including those in hair follicles and the gastrointestinal lining, leading to common side effects like hair loss and nausea.
The monitoring process during immunotherapy is meticulous, as medical staff are prepared to halt treatment at the first indication of complications. One notable advantage of immunotherapy is its potential effectiveness against brain tumors, where traditional chemical treatments face significant challenges due to the blood-brain barrier.
Alternative treatments, such as maintaining a healthy lifestyle, have complemented my conventional therapies. I ensure regular sun exposure for vitamin D, supplement with fish oil, and have previously incorporated sauna sessions into my routine, which I believe significantly aided my health during my first cancer battle.
Faith and Positivity: Key Components of Healing
My Christian faith has been instrumental in fostering a positive outlook during my journey. Nevertheless, individuals from all backgrounds can find solace through various mindfulness practices and techniques. Laughter has also played a crucial role in my healing—rewatching classic shows like "I Love Lucy" and "Frasier" has provided much-needed joy and laughter throughout my treatment.
Writing a Book: A Future Endeavor?
A friend recently suggested that I document my cancer journey in a book. While I'm uncertain at this point, I may pursue it if my energy levels improve. As I continue to fight stage IV cancer, any assistance with medical expenses would be greatly appreciated, along with support for my writing endeavors.
