Tumor recurrence remains a challenge after complete resection of malignant pleural mesothelioma (MPM). Stem cell activation by the hedgehog pathway was detected in MPM, thus we hypothesized that the local application of a hedgehog antagonist could suppress the growth of MPM after resection. Here, we aim to use an immuno-competent rat bioluminescent MPM model to test the efficacy of local intracavitary treatment with the FDA approved hedgehog antagonist in the prevention of MPM recurrence.
