PPARG and neoplasm: The PPARγ protein expression in tumor tissue was dependent to the receiving of chemotherapy treatment (OR = 1.27, CI = 1.13–1.43, P-value < 0.0001), however to describe the exact impact of chemotherapy on the PPARγ expression pattern and also the possible effect of PPARγ over expression in the patient’s level of response to the chemotherapy, further mechanistic study is required and it cannot conclude from the present study.
