The antiEGFR monoclonal antibodies cetuximab and panitumumab have been proven to be efficient in MCRC. The degree of EGFR expression (as confirmed by immunohistochemical analysis) did not correhte with the clinical response. In this review, we describe the current status of markers that might identify patients who are likely to benefit from treatment with cetuximab or panitumumab. These molecular markers include KRAS mutations, EGFR copy number, EGFR ligands (EGF, epiregulin), cyclin DI, IgG FcγR (FCGR2A-HI31R and FCGR3A-V158F), and nuclear factor-κB, that are crucial to avoid anti-EGFR treatment toxicity and reduce treatment cost.

Objective To study the effects of perinatal and postnatal cytomegalovirus(CMV) infection on infantile physical development and nerves mental growth. Methods We observed forty-eight cases of perinatal and postnatal CMV infection infants and twenty-two cases of non-CMV infected infants. We compared the physical development between two groups at birth ,3 months and 1 year of age, and evaluated development quotient (DQ) at 1 year of age. Results There were no significant differences of baby length,weight, head circumference between two groups at birth and 3 months (P > 0.05). The averages of baby length,weight,and head circumference were all in the normal range,which showed no significant differences between two groups(P > 0. 05). There were no significant differences in DQ of rough movement,accurate movement, adaptability, language and sociality ability between two groups at 1 year of age (P > 0.05). The averages of total DQ were in the normal range, which showed no significant difference between two groups as well (P > 0. 05). According to the evaluation hierarchies, DQ values of two groups were mostly in normal level range, and there also was no significant difference(x2 = 1. 026, P > 0. 05). Conclusion The perinatal and postnatal cytomegalovirus(CMV) infection has no significant adverse effects on infantile physical development and neuro-psychological development.
