Therapeutic Drug Monitoring of Protein Kinase Inhibitors in the Treatment of Non-small Cell Lung Cancer.

Targeted therapy with protein kinase inhibitors (PKIs) represents one of the important treatment options for non-small cell lung cancer (NSCLC). It has contributed to improve patients' survival and quality of life significantly. These anticancer drugs are administrated orally in flat-fixed doses despite the well-known large interpatient pharmacokinetic variability and the possible need for dose individualization. To optimize and individualize dosing of PKIs, and thereby increasing the effectiveness and safety of the treatment, therapeutic drug monitoring (TDM) is the most frequently mentioned method. Unlike other areas of medicine, TDM has been rather exceptional in oncological practise since there is a little evidence or no data for concentration-effect relationships of PKIs. Therefore, the aim of this review is to summarize the pharmacokinetic characteristics of PKIs and provide the evidence supporting the use of TDM for personalised treatment of patients with NSCLC.

Intrapleural alteplase therapy: what are the knowns and unknowns?

In pneumology, enzymatic properties of plasmin are used to disrupt fibrin adhesions and septations formed during pathological conditions of the pleural cavity. In that case, fibrinolytics are administrated locally via a chest tube in the pleural cavity to evacuate pathological effusion. Although the first intrapleural administration of fibrinolytic occurred seventy years ago, there has been no consensus on dosing or a uniform procedure of their application. The aim of the article is to summarize current knowledge of alteplase usage in pneumology and discuss practical aspects of its intrapleural application regarding specific possibilities in the Czech Republic.
