Abstract

Survival outcomes for patients with glioblastoma (GBM)are universally poor with only a small percentage of patients surviving five years beyond initial diagnosis. Activation of the immune system against tumor cells is the basis of immunotherapy and aims to facilitate long-term immune surveillance and tumor suppression. Cytomegalovirus (CMV)has emerged as an immunologic target in GBM given that tumor cells have been shown to express the CMV-associated proteins IE1 and pp65. Moreover, vaccine therapy targeting CMV antigens has promoted improved survival outcomes with long-term survivors. In this report, we present the case of a 69 year-old woman with GBM who survived seven years post-diagnosis. Following tumor resection, the patient underwent concomitant radiation and temozolomide therapy that was complicated by CMV colitis and abdominal abscesses. Despite not receiving adjuvant temozolomide, the patient demonstrated a five year progression-free survival before requiring re-resection for radiation necrosis. Following re-resection, the patient survived for two additional years. As the patient's tumor stained positive for CMV antigens IE1 and pp65, it is hypothesized that she developed an immune response against CMV during recovery that contributed to anti-tumor surveillance and prolonged survival. Overall, this case supports further investigation into the role of CMV and immunotherapy in GBM.
