Fig. 2From: High infiltration of mast cells positive to tryptase predicts worse outcome following resection of colorectal liver metastasesTissue samples from resected primary lesions were stained with monoclonal antibodies to tryptase. The log-rank test was used to compare the number of mast cells (MCs) in primary lesions and metastatic lesions. There was no correlation between these parameters (r = 0.04, p = 0.73)Back to article page
