Oamenii de ştiinţă canadieni de la Universitatea din Otawa au modificat virusul folosit pentru producerea vaccinului împotriva variolei. Virusul astfel obţinut, numit JX-594, a fost testat pe 23 de persoane bolnave de cancer.
Opt dintre acestea au primit intravenos o doză maximă a noului tratament viral, iar la şapte dintre ele, virusul a atacat numai celulele maligne, nu şi pe cele sănătoase.
De asemenea, la şase bolnavi care au primit aceeaşi terapie, tumoarea nu s-a mai dezvoltat. Deşi nu tratează efectiv cancerul, noul tratament este promiţător, permiţând dezvoltarea unor terapii eficiente.
„Acest nou studiu este important pentru că arată că un virus folosit până acum pentru vaccinarea a milioane de persoane împotriva variolei poate fi modificat astfel încât să trateze intravenos cancerul, chiar dacă boala s-a răspândit în tot corpul”, a declarat profesorul Nick Lemoine, cercetător oncolog.
