Shorter OS was associated with peritoneal carcinomatosis (HR = 2.00; 95% CI = 1.25-3.21; P = 0.004), ascites (HR = 1.66; 95% CI = 1.19-2.31; P = 0.003) and positive CEA (HR = 1.41; 95% CI = 1.10-1.82; P = 0.007).
CEA to peritoneal carcinomatosis index (PCI) ratio is prognostic in patients with colorectal cancer peritoneal carcinomatosis undergoing cytoreduction surgery and intraperitoneal chemotherapy: A retrospective cohort study.
We used colorectal xenograft (HT29/Ts29.2) and peritoneal carcinomatosis (A431-CEA-Luc/35A7) as tumor cells/mAbs models and fluorescent tetrazines (TZ).
CEA RT-PCR is useful as a prognostic marker for increased risk of cancer death and peritoneal carcinomatosis, and might be useful in the clinical setting for selecting patients for various adjuvant treatments.
