^aThe primary carcinoma of these two patients was previously resected, thus detailed information was not available.

^bThe RNA quality of the primary carcinoma in these two patients was suboptimal for microarray evaluation.

^cPR, primary carcinoma; LV, liver metastasis; LU, lung metastasis; LN, lymph node metastasis; PE, peritoneal metastasis.
