Cannabinoid receptor type 1 immunoreactivity and disease severity in human epithelial ovarian tumors

The recorded data show that the expression of CB1R increased from benign and borderline to malignant tumors. In the near future, endocannabinoid receptors might be used in clinical practice, alone or in combination with other markers, to identify or better characterize ovarian tumors, without considering the great opportunity that they might represent as therapeutic targets.
