Abstract: The present invention relates to the diagnosis of lung tumors. It provides methods suitable both for diagnosing lung tumors on the basis of surgical samples and lung biopsies (here, e.g., with the aid of DNA microarrays) and of liquid biopsies. In the case of liquid biopsies, cell-free DNA (cfDNA) is used. In this context, both particularly suitable analysis methods and particularly suitable sets of methylation markers are described. Means suitable for diagnosing lung cancer by examinining the methylation of a set of methylation markers, e.g., in cell-free DNA (cfDNA) from liquid biopsy samples of patients, wherein the means comprises oligonucleotides which can hybridize to DNA comprising the methylation markers, as well as the use of said methods and means for diagnosing, i.e., e.g., determinination, subtyping and prognostic characterization of lung tumors are also an object of the invention.

Abstract: The present invention relates in a first aspect to a method for diagnosing tuberculosis infection calculating a score based on the expression of a predetermined set of genes and as well as diagnosing or predicting the clinical outcome of the tuberculosis infection based on said score. In another aspect, a method for treatment monitoring and determining treatment duration in an individual with tuberculosis infection is provided. Said method includes the determination of the expression level of predetermined genes, calculating a value based thereon and the therapy monitoring or treatment monitoring and determining treatment duration in said individual accordingly. Moreover, a method for determining the therapy-end of a treatment of tuberculosis infection in an individual affected with tuberculosis infection is provided.
