Association of Polymorphisms in Regulatory Regions of Interleukin-12p40 Gene and Cytokine Serum Level with Colorectal Cancer

The aim of this study was to measure the serum level of the tumour markers CA 195 and CEA in patients with either colorectal or pancreatic cancer both before and at serial intervals after operation. CA 195 and CEA were measured in 199 patients with colorectal cancer and 52 patients with pancreatic cancer. The median concentrations of CA 195 were 3.0 u/ml (interquartile range 3.0-4.5 u/ml) in patients with a Dukes’ stage A lesion, 5.8 u/ml (3.0-18.2 u/ml) in patients with a Dukes’ stage B lesion, 6.1 u/ml (3.0-24.7 u/ml) in patients with a Dukes’ stage C and 23.8 u/ml (11.1-409.0 u/ml) in patients with metastatic disease (normal range 0-7 u/ml). The median levels of CEA were 2.6 ng/ml (1.7-3.3 ng/ml) for Dukes’ stage A, 3.3 ng/ml (1.7-7.2 ng/ml) for Dukes’ stage B, 3.7 ng/ml (2.2-7.9 ng/ml) for Dukes’ stage C and 34.5 ng/ml (13.3-289.4 ng/ml) for metastatic disease. A rising level of CA 195 or CEA after operation suggested recurrence of the tumour. In none of these patients was the recurrence operable. In patients with pancreatic adenocarcinoma, the level of CA 195 was significantly higher in patients with metastatic disease but it did not discriminate between resectable and unresectable disease. The duration of survival correlated with the initial level of CA 195 (Rs = –0.66, p < 0.001).

Early Predictor

593 Background: Inhibition of the EGFR pathway has become a key part in the treatment of colorectal cancer. There were few studies for clinical early predictive markers. To investigate the early magnesium (Mg2+), calcium (Ca2+), albumin (Alb), CEA and CA 19-9 plasma level reductions as a predictor for clinical outcome in terms of progression free survival (PFS) and overall survival (OS). Methods: 200 patients (pts) with mCRC treated by Pmab contained chemotherapy were retrospectively registered from 20 centers in Japan (HGCSG 1002 study). Of these, the pts that were refractory to or intolerant for 5-FU/ irinotecan/ oxaliplatin, and were never administered anti-EGFR-antibody, were included in this analysis. Mg2+, Ca2+, Alb, CEA and CA19-9 plasma levels were obtained from medical records. The differences in terms of PFS and OS according to the presence of Mg2+, Ca2+, Alb, CEA and CA19-9 reductions were evaluated by the log-rank test. Results: Of 67 pts were able to evaluate for this analysis. Pts’ characteristics were as follows: male/female 38/29, median age 64 (range 45-81), ECOG PS (0/1/2- ) 45/17/5. Response rate and disease control rate were 16.4% and 65.7%, PFS and OS were 4.3 m and 12.4 m, respectively. There were no correlations between Ca/Alb plasma level reductions and PFS/OS. Mg2+ reduction of at least 50% respect to the basal value during the course of treatment was significantly correlated with improved OS and PFS (OS, P=0.03; PFS, P=0.01), but the early reduction (until the 4th week or the 8th week after start of chemotherapy) was not correlated with OS and PFS. An early CEA serum level reduction of at least 40% until the 8th week was significantly correlated with improved OS and PFS (OS, P=0.04; PFS, P=0.07), moreover of at least 30% until the 4th week was correlated to longer PFS (P=0.053). Similar results were seen in CA19-9. Conclusions: An early CEA plasma level reduction of at least 30% or 40% was suggested to be a predictor for PFS in Pmab containing chemotherapy for mCRC pts. Although Mg2+ serum level reduction was correlated to clinical outcome, but could not show that is an early predictor for PFS and OS in our study.
