Prostate cancer is suffered by 60% of men

The prostate cancer It is the second most common cause of death in men of all ages. Your treatment depends on the stage you are in. The speed of growth of the disease and its differentiation from the surrounding tissue helps determine this stage. Among the treatments are: surgery, radiotherapy, chemotherapy or control of hormones that fight cancer.

According to information published on, a team of researchers from Duke University Medical Center wants to automate and optimize treatment intensity modulated radiotherapy (IMRT) , with previous clinically approved treatment to create new plans and improve the tool.

According to the journal Seminars of Radiation Oncology, the prostate cancer It is also one of the easiest to treat, since 90% of patients who undergo IMRT in the early stages are free of the disease after five years.

Vorakarn Chanyavanich , one of the researchers at Duke University Medical Center, states that each patient arrives with their own geometry and must have their plan personalized treatment . The process is done manually and takes about four to six hours per patient. "What we would like to do is to discharge the dose for the tumor, preserve the critical organs and also reduce the time of treatment planning," he said.

IMRT uses three-dimensional images of tumor cancerous and the surrounding tissues to determine the radiation according to the size and shape of the tumor . The radiation doses are personalized for each patient, with the aim of maximizing the dose to the tumor and minimizing the radiation received by the surrounding healthy tissues, mainly the bladder, the rectum and the femoral.

In this way, in less than a decade, IMRT has become the treatment of prostate cancer Most common and successful, but the development of individual plans is still a process that consumes time obtained through trial and error.


Risk factor's

  1. Starting at age 50 in men with no family history, and at 40, in men with a family history
  2. A man has a 30% chance of having prostate cancer at age 50, progressively increasing the risk up to 80% at 80 years
  3. At 65, the risk ranges between 30 and 40% of men
  4. Overall, 60% of men develop prostate cancer during their lifetime
  5. Diets excessively rich in fats, especially of animal origin, milk and its derivatives, could favor its development
  6. Other detrimental factors can be the lack of exposure to the sun, the deficit in vitamin D and the consumption of alcohol
