Cuba – Battling cancer with biotechnology
Cancer is the second leading cause of death in Cuba, after cardiovascular diseases. It is estimated that every year about 21 000 people die of cancer on the island and more than 31 000 cancer cases are newly diagnosed.
“Cancer is one of the major killers in Cuba. This is partly because people live longer but also because many have adopted unhealthy lifestyles. Too many people use alcohol harmfully, eat unhealthily and use tobacco,” says Dr José Luis Di Fabio, the head of the WHO Country Office in Cuba. “Among men, prostate and lung cancers are the most common types of cancer, and among women breast and cervical cancer are at the top of the list.”
Comprehensive national cancer plan
In response, Cuba has followed WHO recommendations, putting in place a comprehensive national cancer plan that ensures universal access to all levels of health service - from cancer prevention, through diagnosis and treatment to palliative care. The plan is underpinned by a strong primary health care system that enables doctors to see their patients regularly and catch health problems at an early stage. Suspected cancer patients are referred to specialized centres for diagnosis and appropriate treatment.
Major investment in biotechnology
To back this up, the Government has made a major investment in biotechnology. Cuban researchers and scientists have recently made significant progress in their search for new cancer treatments and tools to improve diagnosis and prevention. In 2008, for example, the Ministry of Health registered a first vaccine for therapeutic treatment of advanced lung cancer developed by the Havana-based Centre of Molecular Immunology (CIM). It is one of the biotechnology spearheads in Cuba that is focusing on cancer treatments and vaccines. A second vaccine against the same type of cancer was patented in the beginning of 2013.
“Biotechnology is key to transforming cancer from a deadly disease into a chronic one,” says Dr Agustin Lage Davila, the General Director of CIM. “Our drugs make chemo and radiation therapies more effective and less toxic. This helps us to achieve our ultimate goal: a longer life and a better quality life for our patients.”
Anti-cancer drug nimotuzumab
The Centre has also developed the anti-cancer drug nimotuzumab, to treat advanced tumours, for example in the head, neck and brain. Nimotuzumab is a “monoclonal antibody” that mimics human immune cells and binds to specific target molecules of cancer cells. It targets a protein that can cause uncontrolled cell division and growth. The drug is currently going through clinical trials in Japan and Europe.
Continuing political and financial support for biotechnology
Even in times of economic hardship, the Cuban Government has remained constant in its political and financial support for biotechnology. In the last 20 years it invested around one billion US dollars in research and development. Today, the Cuban biotech industry holds around 1200 international patents and markets pharmaceutical products and vaccines in more than 50 countries. Exports are soaring and generate yearly revenues of several hundred million dollars.
“More than 90 new products are currently being investigated in more than 60 clinical trials. These numbers are expected to grow,” says Di Fabio. “The tremendous benefit from this focus on health biotechnology is that it is producing more affordable drugs to tackle diseases that run rampant in low- and middle-income countries.”
