HAVANA, 10 janeiro 2011 (AFP) - Cuba registrou a primeira vacina terapêutica contra o câncer de pulmão, após testar sua eficácia em mais de mil pacientes sem que tenham ocorrido efeitos colaterais, informou esta segunda-feira uma autoridade científica.
"Foram mais de 15 anos de pesquisas", disse ao semanário 'Trabajadores' Gisela González, chefe do projeto desta vacina - denominada CIMAVAX-EFG -, cujo objetivo é transformar o câncer de pulmão avançado em uma doença crônica controlável.
O registro permite usar a vacina maciçamente no país, bem como nos mil pacientes aos quais foi administrada durante os testes, e "atualmente seu registro avança em outras nações", disse a especialista.
"Uma vez que o paciente termina o tratamento com radioterapia ou quimioterapia e é considerado um paciente terminal sem alternativa terapêutica, neste momento é aplicada a vacina, que ajuda a controlar o crescimento do tumor sem toxicidade associada, e pode ser usada como um tratamento crônico que aumenta a expectativa e a qualidade de vida do paciente", ressaltou.
A vacina "está baseada em uma proteína que todos temos: o fator de crescimento epidérmico", acrescentou González.
"Igualmente se avalia a forma de empregar o princípio desta vacina em outros tumores sólidos (em próstata, útero e mama), que podem ser alvo deste tipo de terapia. Existem resultados importantes, mas é preciso esperar", concluiu.
Opinião dO Cachete:
Alguém sabe o nome do país com o maior índice de incidência de câncer do mundo???? Vai ser muito irônico exportar vacina anticâncer para lá, não vai? E isso com o embargo da ONU!!!!!

Lung cancer vaccine 'extends terminal patients lives'
LUNG CANCER
February 19, 2009
By Shasta Darlington CNN
Terminal lung cancer patients are LIVING LONGER thanks to the world's first registered lung cancer vaccine, a leading Cuban scientist says.
Dr. Gisela Gonzalez has spent years researching the vaccine which the Cuban government approved for the use of the general public last year.
Gonzalez and her team have worked on developing the CimaVax EGF vaccine at the Cuban Center of Molecular Immunology since the early 1990s.
She says all those years of hard work have finally paid off as trials show that Cubans with lung cancer are LIVING A LITTLE LONGER after having the vaccine.
"One of my early patients was a 32-year-old man when he started taking the vaccine. I had a son that age," the scientist told CNN.
"Now he's 35. He's living and working. He visited us the other day and said he's thinking about having kids."
Gonzalez says that more than 700 patients have received the vaccine over the years, many of them in seven clinical trials in Cuba, Canada and the UK.
More than 400 advanced lung cancer patients received the Vaccine CimaVax EGF in the trials, according to the Latin American News Agency.
The trials showed that the drug extended the life of terminal patients by an average OF FOUR MONTHS, and in some cases several years, compared with those patients who only received traditional therapies. Younger patients tended to fare better.
"It has the potential to be very important," according to Dr. Howard Burris, director of drug development at the Sarah Cannon Research Institute in Nashville, Tennessee.
He said the results were COMPARABLE to those being produced by TWO OTHER lung cancer vaccines, GVAX and BLP 25, being DEVELOPED IN THE UNITED STATES.
"Larger trials will show there are subsets that it's very good for and for others it's not relevant," he said.
CimaVax EGF does not prevent or cure lung cancer. It is a therapeutic vaccine which stimulates the patient's body to make an antibody against the epidermal growth factor (EGF), which is a key driver causing lung cancer cells to grow.
It is used in conjunction with chemotherapy and radiation therapy which reduce the size of the initial tumor.
"With this kind of product, maybe cancer, advanced cancer, can be treated like any other chronic disease like diabetes," Dr. Gonzalez said during a recent tour of her modern laboratory in Havana.
Medical services, even the most costly, are provided free of charge in communist Cuba. CimaVax EGF is now part of routine treatment for advanced lung cancer patients.
QUEM VAI EXPORTAR MESMO???
