Swimming Upstream: My Struggle and Triumph Over Cancer and the Medical Establishment: New Hope in Cancer Treatment
In February 2014, two groups of scientists in New York City presented the early data of what can only be described as a phenomenal study with phenomenal results.
In a study using sixteen adult leukemia patients, scientists took samples of each patient’s T-cells and samples of his or her cancer cells. Under laboratory conditions, they trained those T-cells to recognize certain specific traits of that patient’s leukemia cell and then attack to kill it—it was like teaching a drug-sniffing dog to find the cache of heroin. These were called “smart T-cells.”
The next step was crucial, dangerous, and amazingly clever.
The researchers cloned millions of these specially trained T-cells and then went back to the patients and gave them very toxic chemicals that destroyed their “dumb” T-cells—those that were still fooled by the cancer’s camouflaging. They then replaced them with the trained smart T-cells.
Once infused, the trained T-cells set out like an elite commando force equipped with exact GPS coordinates and hunted down and killed the cancer cells.
The success rate of achieving a complete response was an astounding 88 percent!
The incredible success of that small study, and several others since, has sparked an explosion of interest and further studies by various medical centers and pharmaceutical companies worldwide, who are spending billions of dollars in similar research. These investments are sure to be returned many times over, of course. But it can only mean good things for cancer patients. Costs for adoptive T-cell transfer treatments now are prohibitive for individuals—upwards of $500,000 for one patient, which is totally unacceptable. But that will change in the near future.
And there were complications, of course, with ominous results for one patient.
In one unfortunate patient, a man from New York City with Her2-positive colorectal cancer, doctors infused T-cells trained to seek out and kill Her2-positive cancer cells. The man went into respiratory arrest within fifteen minutes. His health continued to deteriorate over the next few days despite the best efforts of the medical experts. He died after four days when his lungs shut down completely. There was nothing they could do to save the patient.
An autopsy showed that the patient’s normal lung cells had traces of Her2. The “smart” T-cells had been attacking and killing the healthy lung tissues as well as the cancer.
These trained T-cells are like heat-seeking missiles. They will attack and kill as they have been trained to do—and there was no reversing this once they were set loose.
You lose any control over the missile once it is fired.
This unfortunate incident led to a temporary halt of all further experimentation in this area. The focus was shifted to try to find a way to control these smart T-cells after they were infused into the patient’s bloodstream. How do you stop these commandos if they go rogue? How do you destroy a wayward missile?
A few different strategies have been developed to accomplish that. One of those is the development of what is called a “suicide gene”—and it is truly the stuff of science fiction. Now scientists can tag T-cells with this suicide gene. If they go haywire and start attacking normal cells, doctors can prompt them to destroy themselves, or commit suicide.
The first couple of the CAR-T Cell Therapies, as these are called, have already received an FDA approval and the newer & better ones are sure to follow.
It is nothing short of amazing. Today we are on the cusp of advances that were not even imagined just a few years ago. Now when someone disconsolately calls me for advice and tells me they have been given no more than two years to live, I tell them not to panic or lose hope. I emphasized that two years is an eternity when it comes to medical advances, the way science is exploding in its efforts to cure cancer.
“Take heart,” I tell them. “Every year, new drugs and modalities are being developed. In two or three years, you have no idea what new miracle drug may come out.” I suggest optimism and advise they focus on positive thoughts, avoid negativity and depression, refuse to panic, eat healthily, remain physically active, meditate, enjoy every little pleasure in life, and, as much as possible, avoid stress. Most of all, do not give up hope.
All that will boost your immune system and will go a long way toward beating this dangerous enemy.
Two years—or even a year—given the ways that science is moving ahead, is a terrific pronouncement. This, in no way, is meant to paint an unrealistically rosy picture. Cancer has been and continues to be an extremely deadly disease. Even though the death rate from cancer has gradually and steadily declined since 1990, there are still far too many patients dying from it. In the United States, cancer continues to be the second biggest cause of death, behind heart disease only. Over half a million patients die from cancer each year in the United States alone. More than eight million lives are lost worldwide.
I am fully aware of all that. Yet, there is no doubt that we are entering a much better and far more hopeful era. At no other time in the history of medicine have we been this tantalizingly close to achieving a major victory against cancer, a game-changing victory that could, possibly forever, change the cancer outlook.
I believe this with all my heart.
Sajjad Iqbal is a physician and cancer survivor. Almost 17 years ago, Sajjad learned that he had an extremely rare and most malignant type of parotid cancer called Salivary Duct Carcinoma. He was given a 30% chance of surviving for 2 years. Because of Sajjad’s medical training and his unwavering sense of hope & determination, he was no ordinary patient. Sajjad researched his condition and proposed a treatment method for himself that stopped the progression of cancer cells. Although Sajjad is still living with, and still fighting, the cancer, he continues to defy the odds with no end in sight. To inspire other cancer patients, Sajjad Iqbal has chronicled his amazing cancer journey in the form of a book titled, “Swimming Upstream, My Struggle and Triumph over Cancer and Medical Establishment.”
