TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['The immunohistochemical detection of Enhancer of zeste homologue 2 (EZH2) proved to be a useful tool to recognize the malignant nature of tumors in a wide variety of neoplasms. The histological diagnostics of salivary gland tumors is a challenging task, and a reliable marker of malignancy would be extremely helpful.', 'EZH2 expression was investigated in 54 malignant and 40 benign salivary gland tumors of various histological types by standard immunohistochemistry.', 'The majority (n\u2009=\u200952) of the malignant tumors stained positively, while all the investigated benign tumors were negative for EZH2.'] Is eZH2 a sensitive marker of malignancy in salivary gland tumors?
OUTPUT:

agent
