Why rare cancers have a lower frequency and worse prognosis



Visit to the country, David Humphreys, Director of the Health Police at the Intelligence Unit of The Economist, presented a report on the state of the approach to rare cancer in Latin America, including the situation in Argentina.

The investigation, called Types of Cancer, Uncommon in Latin America: Challenges and Current Opportunities for Progressto generate more understanding of that challenges for improving health care and the prognosis of patients with some rare cancers, which are less than six cases per 100,000 inhabitants per year, are concentrated on Argentina, Brazil, Colombia and Mexico.

Among the collected data are the main obstacles to treatment and the possibilities for improvement of the obtained results in order to attract the attention of the participants in this problem.

"Epidemiological data suggest that the incidence of these cancers in Latin America is generally lower than in those with higher incomes. When analyzing the incidence and mortality rates, rare cancer has a worse prognosis in the Latin American countries than in the richer countries"Local survival rates are comparable to those in India, China and South Africa," Humphreys said.

On the basis of the studies carried out by The Economist In response to a request from Merck, the Intelligence Unit, they have developed a number of recommendations to optimize the approach to these conditions:

Developing and implementing plans or strategies at national level: Like Latin European countries, Latin America can create a regional project to ensure consistency in dealing with rare cancers. This would help stimulate the development and implementation of strategic plans.

Create detailed records at national and regional level: Placing records that link cancer population data is essential for obtaining epidemiological data, a plan to prevent rare cancers and carry out control activities. Developing a regional registry is the natural step towards standardizing data collection on rare cancers in Latin America.

Generating co-operation in the field of research at national, regional and international level: Oncology research is essential to increase understanding of rare cancers and improve the treatment of the disease. It is recommended that Latin American countries participate in national, regional and international research initiatives on rare cancers and thus contribute to global knowledge by taking advantage of the exchange of ideas.

Improving treatment through centers of excellence: It is essential to develop centers of excellence and networks of experts or working groups. Expert networks have the potential to improve outcomes and reduce inequality as they promote better knowledge of rare cancers by providing support to treatment centers. European and North American models can be adapted to be applied in Latin America.

David Humphrey stressed that "in Latin America, autoimmune diseases and access to healthcare were historically very important issues for legislators and participants in the problemHowever, given that life expectancy and overall health have improved in the region, with a longer population duration there is an increase in the incidence of chronic diseases. "Cancer is a particularly important factor, with more than one million new cases per year in Latin America and the Caribbean.

Although much progress has been made in early diagnosis and national prevention plans, there is still a lot to do, such as developing a patient register and fighting disparities in access to treatment. In the case of rare cancers, the challenge is even greater.
