Do radio- and chemotherapy variably affect the general immunocompetence of lung cancer patients?
Two cancer treatment modalities--radio- and chemotherapy--variably affect the immune status of lung cancer patients. The initial great disturbances of general immunity parameters are further aggravated by radiotherapy. Unlike RT, chemotherapy exerts no suppression at all; on the contrary, it tends to normalize some of the parameters of cellular immunity of lung cancer patients.
Our data suggest that a high maintenance dosage of clopidogrel (150 mg/day) is associated with a reduced risk of definite stent thrombosis and MACE compared with a maintenance dosage of 75 mg/day. The frequency of hemorrhagic accidents was similar between the two groups, underlining a positive benefit-risk ratio of this strategy in clopidogrel-resistant patients. These findings deserve confirmation in a prospective, well conducted study.
