Cancer Cure: Inching Towards the ‘Holy Grail’?

Cancer Cure: Inching Towards the ‘Holy Grail’?

In a Press Conference on August 20, 2015, the 39th President of the United States, now 90-year-old  Jimmy Carter, revealed (video) that during a liver surgery earlier this month the doctors diagnosed that he has cancer. The type of cancer that he is suffering from is called melanoma, which has already spread to his liver and brain. Medical jargon would term it as deadly metastatic cancer.
Though the surgeons have removed the liver tumor, and well-targeted radiation treatment for four other small tumors in his brain has already been initiated, the original site of the melanoma, the lethal skin cancer, has reportedly not been found, as yet.
Mr. Carter’s medical treatment has started with an infusion of a new class of drug that uses the human immune system to fight cancer cells. The drug has been reported to work not only in advanced metastatic cancer, but also in the old age of patients. The former American President appears optimistic about the treatment outcomes with this new therapy, ‘placing his fate in the hands of God’, though initially he thought that he had just weeks to live.
I shall deliberate in this article, in an easy to understand language, though briefly, the promises offered by two latest options for cancer cure. One of these two, has just become available to patients and the other one, after an initial jaw-dropping success, is undergoing further tests in a renowned research laboratory of the United States.
Two novel pathways for cancer treatment:
Until recently, surgery, radiation and chemotherapy used to be the three common options for cancer treatment. One breakthrough option has just been launched and more in the offing.
In search of a cure for cancer, pathbreaking outcomes of medical research, especially in the following two areas, are significant:
A. Immunotherapy: It is a revolutionary approach to cancer treatment. The first of this novel class of drugs has just come to the market, with which Mr.Jimmy Carter is now reportedly being treated.
B. Re-programming cancer cells back to normal: Success has just been achieved in laboratory studies with this technique. It holds a strong promise to cure cancer, universally.
A. Immunotherapy:
On June 1, 2015, in an article titled, ‘Cure for terminal cancer’ found in game-changing drugs, “The Telegraph” – well-regarded international news daily, reported on anti-cancer immunotherapy drugs, as follows:
“Terminally ill cancer patients have been ‘effectively cured’ by a game-changing new class of drugs. In one trial, more than half of patients who had just months to live saw deadly tumors shrink or completely disappear.”
“In recent days, the results of trials of a number of treatments which harness the body’s immune system have been announced at the American Society of Clinical Oncology’s annual conference in Chicago. They show promise in the fight against skin cancer and lung disease.”
As we know, most of the cancers are deadly. All these grow and spread, as they manage to hide from the immune system, disguising the life-threatening danger. Thus, medical research scientists pondered that the human immune system could play a critical role in the fight against cancer and even cure, by harnessing its ability to fight the deadly disease, effectively and decisively.
To achieve this goal, this class of new cancer drugs work by allowing the body to recognize and attack cancer as any other harmful invader to the body. It effectively blocks a cellular pathway that hinders the ability of the human immune system to attack cancer cells.
At present, to treat different types of cancer, more number of immunotherapy drugs are undergoing clinical investigations.
Brilliant treatment outcomes, but not universal:
It has been reported, about one third of patients taking immunotherapy for the treatment of cancer experienced positive results. Those who responded to this therapy, showed immediate effect with their tumors shrinking or vanishing in a matter of weeks. As a result, the patients who had no more than weeks or months to live, just as former US President Jimmy Carter, have gone into remission for years and continuing with their normal lives.
It has also been reported, otherwise such patients could expect to live just nine months, if given standard treatment of cancer. Researchers said, they were hopeful that half of the patients responded to immunotherapy would end up “living disease-free”.
These drugs are expensive, costing roughly US$150,000 per year, which is a part of a different debate altogether.
Not a ‘magic bullet’:
Besides its high cost and outstanding quality of results, it is worth noting that immunotherapy is not a ‘magic bullet’ for all types of patients and in all cancer. It, therefore, throws a challenge for the oncologists to understand, why immunotherapy benefits only to some cancer patients, and who are those patients?
Moreover, there is a possibility of immunotherapy sending immune system of some patients to overdrive, precipitating auto-immune disorder that may attack also the healthy cells.
Thus, immunotherapy is not the ‘Holy Grail’ for the treatment of cancer, neither it is nowhere near a perfect drug for the treatment of all types of cancers in all patients.
Two key findings:
In this regard, two key findings of the researchers on immunotherapy are as follows:
  • Roughly around 15 to 20 percent of patients could experience shrinkage or remission of cancer
  • Half of the patients who responded found it lasting for at least six months
Thus, immunotherapy can at best be a cure for only some terminally ill cancer patients, mostly for some time, but not for all.
“In the hands of God”:
All these factors on immunotherapy probably would help us to understand, why an erudite person like Mr. Jimmy Carter said, though optimistic about the new treatment, he is placing his fate ‘in the hands of God’.
B. Re-programming cancer cells back to normal
The question, therefore, comes up now, if immunotherapy is not the ‘Holy Grail’ for cancer treatment that the research scientists have been intensively searching for, is there anything else coming up for cancer cure?
It appears so. A totally different approach to re-program the cancer cells back to normal has very recently been reported by Mayo Clinic’s Florida Campus in the United States. With this, cancer researchers’ dream of making the tumor cells morphing back to normal cells, they once were, would probably come true.
The research findings, published in Nature Cell Biology on August 24, 2015, represents ‘an unexpected new biology that provides the code, the software for turning off cancer,’ said the senior investigator of this study.
In the normal process, cells in the human body divide constantly to replace themselves and stop dividing when they have replicated sufficiently. However, unlike the normal cells, cancer cells do not stop dividing, they go out of control, leading to huge cell reproduction and tumor growth.
For the ultimate cure of cancer, scientists at Mayo Clinic have now reportedly succeeded in reversing the process responsible for the normal cells from replicating too quickly.
Possible cure now within sight?
This could ultimately lead to a newer class of breakthrough treatment that would be able to reverse cancerous growth in the human body, possibly curing cancer, without the need of surgery, chemotherapy, radiation or even immunotherapy.
Scientists at the Mayo Clinic have said that their initial experiments in some aggressive types of cancer are quite encouraging. They have successfully done this in very aggressive human cell lines from breast and bladder cancer.
Towards the ‘Holy Grail’:
In pursuit of finding a cancer cure, research scientists have been making commendable progress, over a period of time.
In the last few years, spectacular breakthroughs in treatment of cancer have been possible from the increasing genetic and biological understanding of the researchers, especially in ascertaining exact defects in the DNA code of human genes that cause cancer.
Ability to sequencing human genome has offered a key tool to the researchers to compare the DNA codes of cancerous and normal cells and identify the differences.
From within the 20,000 human genes, around 500 cancer genes have been reportedly discovered and are being catalogued. Clear understanding of what happens precisely when the cells divide uncontrollably and cancer spreads in different parts of the patients’ body, is taking place with commendable progress of various research initiatives in this area.
Based on the current knowledge on human genome, a number of new drugs have been and are being developed to target the cancer-causing genes with great accuracy. Such types of drugs are called ‘personalized medicines’, as these act on specific gene abnormality of patients related to certain types of cancer. Sophisticated laboratory tests facilitate treatment with ‘personalized medicines’. These are more effective with lesser side-effects, as compared to generally used anti-cancer drugs, prescribed to all cancer patients.........

Health Care In India: Disrupt The Status Quo

Health Care In India: Disrupt The Status Quo

Over decades, we have been trying to ferret out the unfeigned reasons of failure for India to provide access to reasonably affordable, quality health care to all its citizens, but in vain. The quest to know its rationale becomes more intense, as we get to know, even some developing countries in Asia, Africa and Middle East are taking rapid strides to catch up with the health care standards of the developed countries of the world.
In the last few years many such countries, such as, Thailand, Turkey, Rwanda and Ghana, besides China, have successfully ensured access to quality and affordable healthcare to their citizens through well-structured national initiatives. Governments of economically poorer countries, such as, Sri Lanka and Bangladesh too are making rapid progress in this direction. All these commendable health care initiatives are protecting the most vulnerable populations in their respective countries from getting swept away by extreme poverty.
No more than just assurances:
In India, economic and social costs of public health care infrastructural inadequacy, consequent low access and inefficient delivery mechanism keep going north, unabated, barring a small number of States. Over decades, Union Governments of all political dispensations have been making no more than incoherent promises and that too in bits and pieces on reform in public health care services. As on date, no Union Government has articulated a comprehensive pathway to achieve this goal, in tandem with the States, specifying required time-frames and making commensurate budgetary allocations.
Despite the legacy factor, the incumbent Government as well, has not taken any tangible measure in this direction, just yet, besides giving similar in-coherent assurances. Nor has it clearly articulated that providing access to quality health care for all, at a reasonable cost, is one of its top areas of priority in the widely publicized ‘National Development Agenda’.
Agonizing wait continues:
That the Government is now in the process of drafting a National Health Policy to meet the rising demand for sustainable healthcare across the country, was announced by the Secretary – Health & Family Welfare on September 1, 2014. The first draft of The National Health Policy 2015 was placed in the public domain seeking inputs from the stakeholders in January 2015.
That said, agonizing wait of the patients with unfathomable patience still continues for better days of high quality and affordable health care services in India. Palpable feeling of long standing apathy of the decision makers in this area keep lingering simultaneously.
Two critical admissions:
Besides others, following are the two critical and unambiguous admissions in the draft National Health Policy 2015:
  • “The failure to attain minimum levels of public health expenditure remains the single most important constraint.”
  • “Over 63 million persons are faced with poverty every year due to health care costs alone, it is because there is no financial protection for the vast majority of health care needs.”
In my article of January 12, 2015 published in this Blog, titled “National Health Policy 2015 Needs Wings To Fly ”, I deliberated on the draft National Health Policy 2015.
No commensurate budgetary provisions:
Despite being aware of the above facts, the Union Budget for 2015-16 allocated just below Rs. 30,000 Crore for health care in India, without unveiling any longer term picture in this regard, not even a ‘broad brush’ one.
To give a perspective regarding how meagre is this budgetary allocation on so critical an area, I quickly add that on August 19, 2015, Prime Minister Modi announced an allocation of Rs.1.25 lakh crore for the development of only Bihar, just prior to the state going for the assembly election.
Untenable reason:
The Finance Ministers reasoned in his budget speech that post devolution of resources to the states following the recommendations of the 14th Finance Commission, the states will address the issue of healthcare in their respective geographical jurisditions.
However, it does not make much sense to me, if at all. This is mainly because, though health is a state subject, it is still a very critical national issue with an overall dismal performance of the country against most of the ‘Millennium Development Goals’.
Only a ‘National Health Plan’ funded jointly and adequately by both the center and the States with clear budgetary provisions and executed immaculately against clearly measurable performance parameters with specifically assigned accountabilities, could salvage the disastrous consequences of further neglect in the health care space of the country.
Not just deployment of financial resources:
The core issue, I reckon, is not just inadequate deployment of financial resources, but continuation of lack of effective governance in the Union Ministry of Health, as well. And, this is indeed a deadly combination. It has been pushing a large number of patients in India embracing abject poverty every year, as admitted in the draft National Health Policy 2015 of the incumbent Government, but with no visible rectifying measures, as on date.
Dangling carrots, as it were, to the patients by different Union Governments in shedloads, such as, ‘free medicines for all’, ‘free health insurance for all’, ‘free diagnostics for all” and what not ‘for all’, has been continuing forever, with patients having no other choices but to have patience in plenty and probably in perpetuity.
When Primary Health Care itself is a critical issue… :
In such deteriorating heath care environment, when primary health care still remains a key issue mostly in rural India, yet another interesting and tentative assurancereportedly comes from no less than the Union Minister of Health himself on August 18, 2015, when he said:
“The government is working both in secondary and tertiary medical sector and I believe that we need to work out a module in PPP mode to lessen the healthcare burden of common man.”
Having said that, when it comes to providing healthcare services to the poor and the needy, the Honorable Minister, expressed his vision in a notably interesting way, which is reportedly as follows:
How will we be able to give the healthcare facility to helpless is one question that is unanswered…. All stakeholders should answer this question. Enhance the teaching, the training should be at much higher, speed, scale and skill and above all there should be better communication.”
Going beyond just allopathic treatment:
To answer the Health Minister’s above question – “How will we be able to give the healthcare facility to helpless”, one of the many important ways for the Government, I reckon, is to make a decisive and robust move much beyond Allopathic treatment, just as what China has done with its ‘traditional medicines’.
The strengths of traditional Indian medicines need to be properly leveraged with requisite intervention of science and technology and supported by effective awareness building campaigns.
Expand the role of ‘Traditional Medicines’:
Treatment with traditional medicines in India for many well-tried common diseases, has the potential to play an important role in providing access to health care for all, at least in the public health care space of the country, where AYUSH (Ayurveda, Yoga, Unani, Siddha and Homoeopathy) needs to be promoted and encouraged, actively.
It is expected that the new National Health Policy 2015 would have a much greater focus on the traditional systems of medicine – AYUSH, for the treatment of many common diseases.
It appears from various reports, AYUSH system that calls for not very sophisticated technological inputs for diagnosis of common diseases and preparation of medicinal substances, could be made an integral part of the entire healthcare spectrum, starting from the primary health centers.
As a basic preparatory measure to achieve this goal, the rejuvenated ‘Department of AYUSH’ should work, in consultation with the respective domain experts, to chart out an effective and implementable pathway for the development of education and research in Ayurveda, Yoga, Naturopathy, Unani, Siddha, and Homeopathy systems.
Need to increase focus on AYUSH:
It has been widely reported that the use of herbs to treat various common ailments is almost universal among many societies, as these are quite often more affordable than buying expensive modern allopathic medicines.
According to the World Health Organization, around 80 per cent of the population of some Asian and African countries currently use traditional medicines to address their health care needs.
I thought the same holds good for India, as well.
However, from a very recent and credible survey report, I find that the above impression is not quite true for India. Penetration of traditional AYUSH systems of treatment, even within the rural population of India, is currently abysmally low.
According to NSSO’s (National Sample Survey Office) Household Expenditures on Health Survey, conducted between January and June 2014, usage of Allopathy for “spells of ailment” is unusually high both in urban and rural India, as follows:
CategoryAllopathy Treatment %
Rural Males90.6
Rural Females88.7
Urban Males90.4
Urban Female91.0
(Source: NSSO 2014-15)
In the absence of adequate access to safe and cost-effective treatments through public health care infrastructure and delivery systems, be it Allopathic or AYUSH, more number of patients are compelled to seek expensive private healthcare services for their “spells of ailment”, as follows:
CategoryPrivate DoctorsPrivate Hospitals
Male51.324.3
Female49.723.9
(Source: NSSO 2014-15)
AYUSH could play an important role to address such issues, appreciably.
An intriguing recent media report:


    On August 19, 2015, I read an intriguing media report that highlights the following two points on apparently a ‘recently overhauled draft’ of the National Health Policy 2015, as follows:..............
