American scientists have developed a drug that has shown positive results against an aggressive type of ovarian and intestinal cancers, reports ScinceDaily.

It is noted that in 6 of 11 patients who were undergoing treatment, positive clinical changes were recorded.. In one patient with ovarian cancer, tumor development stopped at 89 weeks, in another patient with intestinal cancer a partial response to therapy was observed, lasting for 16 weeks.

New vaccines are created on the basis of patients' leukocytes, which are converted into dendritic cells in laboratories..

The resulting vaccine is injected subcutaneously in patients and the newly formed dendritic cells "get acquainted" with the antigens of cancer cells, as a result of which the lymphocytes begin to attack the cancer..

Of the side effects, scientists note only skin irritation at the injection site..

However, vaccines act only on HER2 positive cancers.. In the future, it is planned to gradually increase the dose of the vaccine and its further testing..

Earlier it was reported that scientists have found a combination of drugs against melanoma.
