A combination of vaccine and chemotherapy sessions were given to patients with glioblastoma boosts survival.

‘A vaccine targeting cytomegalovirus (CMV) antigen pp65, combined with high-dose chemotherapy given to glioblastoma patients boosts survival.’

The results, published in the Journal Clinical Cancer Research, demonstrated a median progression-free survival of 25.3 months and a median overall survival of 41.1 months in eight patients. 




In the remaining three patients, the disease was progression-free for more than seven years after diagnosis, the researchers said.
"The clinical outcomes in glioblastoma patients who received this combination were very striking," said lead author Kristen Batich from the Duke University in North Carolina, US.
The typical median survival for glioblastoma patients is less than 15 months.
To overcome these poor numbers, the researchers took advantage of CMV's affinity for glioblastoma, with the viral proteins being expressed in roughly 90 per cent of these tumors.

Previous work had shown that TMZ generates profound lymphopenia or the loss of immune cells, which offers a unique opportunity to retrain the immune system, explained Batich .

"The dose-intensified temozolomide induces a strong state of lymphopenia. With that comes an opportune moment to introduce an antigen-specific vaccine, which redirects the immune system to put all hands on deck and fight that target," said Batich.
