From: Pancreatic cancer: Circulating Tumor Cells and Primary Tumors show Heterogeneous KRAS Mutations
Distribution of KRAS mutations in CTC and the primary tumor. (a) KRAS mutations in CTC and the primary tumor: Several patients (n = 13) had multiple mutations in the CTC or primary tumor, in 20 cases no tissue was available. (b) Substantial discordance of KRAS mutations in CTC and the primary tumor (n = 9): those with no available tissue samples were excluded (n = 20); 5 were CTC negative. Cyto pos = cytology positive; MS = median survival (in months).
