CEA response merits further investigation as a surrogate endpoint of clinical trials of first-line medical therapy of patients with mCRC, and should be studied as a prognostic factor for those patients who are candidates for multimodal treatment strategies.
Measurements of tumor markers, CEA and CA 19-9, in patients with metastatic colorectal cancer (<i>n</i> = 73) who received cetuximab plus folinic acid, fluorouracil, and oxaliplatin or irinotecan (FOLFOX4/FOLFIRI) as a first-line treatment at our center were retrospectively analyzed.
Progression-free and overall survival of 41 mCRC patients enrolled in the study correlated with baseline levels of CEA, immune-inflammatory markers (neutrophil/lymphocyte ratio, CRP, ESR, LDH, ENA), IL-4 and with post-treatment change in p-ANCA and CD56<sup>dim</sup>CD16<sup>bright</sup>NKs (<i>p</i> < 0.04).
CEA response is associated with tumor response and survival in patients with KRAS exon 2 wild-type and extended RAS wild-type metastatic colorectal cancer receiving first-line FOLFIRI plus cetuximab or bevacizumab (FIRE-3 trial).
A phase 1/2 clinical trial evaluating dosing, safety, immunogenicity, and overall survival on metastatic colorectal cancer (mCRC) patients after immunotherapy with an advanced-generation Ad5 [E1-, E2b-]-CEA(6D) vaccine was performed.
Carcinoembryonic antigen (CEA, CEACAM5) and epithelial cadherin (E-cadherin) are considered as independent tumor markers in monitoring metastatic colorectal cancer.
In the present study, we aimed to determine the prognostic role of initial CEA and CA 19-9 values in metastatic colorectal cancer patients according to the status of K-ras.
A randomized phase II study of immunization with dendritic cells modified with poxvectors encoding CEA and MUC1 compared with the same poxvectors plus GM-CSF for resected metastatic colorectal cancer.
