Fisher's exact test confirmed that the metastasis sites were similar in terms of bcl-2 protein expression, survival, and presence of unresected metastatic disease by the end of the study (Fisher's P = 1.0, P = 0.333, and P = 0.429 for lymph node, subcutaneous, and visceral metastases, respectively). This evidence concerns the gene BCL2 and metastatic neoplasm.
