High levels of granzyme B expression in invasive cervical carcinoma correlates to poor response to treatment

Cancer Invest. 2008 Jun;26(5):499-503. doi: 10.1080/07357900701805678.

Abstract

The present study assessed, in cervical carcinoma, expression levels of seven immune response genes and sought correlation to response to treatment. The expression levels of CD28, CTLA4, ICOS, ICOSL, CD80 and CD86 and granzyme B genes were assessed by real-time RT-PCR in pre-treatment tumor fragments. During the six-month follow-up after treatment, 8 patients presented tumor and 10 survived free of tumor. The only gene whose expression levels were higher in patients with poor outcome (p = 0.03) was granzyme B. Further evaluation, in adequately powered prospective studies is warranted to confirm the data and to translate this observation to the clinical setting.
