The present application relates to the field of cancer, particular to hypoxic tumors. It was found that hypoxia is an important driver for hypermethylation of (promoters of) tumor suppressor genes. As this hypermethylation is a stable signature that is also present in circulating tumor DNA in peripheral blood, detecting this methylation pattern is a surrogate marker for tumor hypoxia. This can be used to adapt therapy as well.

Markers for determining tumor hypoxia

Described are mismatch repair (MMR-)deficient tumors. Markers are presented herein having a high sensitivity to detect whether a tumor is mismatch repair deficient or not. The markers are particularly mutations in microsatellite regions. Accordingly, methods and materials are provided for diagnosing microsatellite instability of a tumor. Such a method comprises determining the presence of these markers. Further, kits are provided to detect the presence of these markers (or subsets thereof) in a sample.

Markers for detecting microsatellite instability in cancer and determining synthetic lethality with inhibition of the DNA base excision repair pathway

The present application relates to the field of cancer, particularly to mismatch repair (MMR&#x2212;) deficient tumors. New markers are presented herein that have a high sensitivity to detect whether a tumor is mismatch repair deficient or not. The markers are particularly mutations in microsatellite regions. Accordingly, methods are provided for diagnosing microsatellite instability of a tumor, comprising determining the presence of these markers. Further, kits are provided to detect the presence of these markers (or subsets thereof) in a sample.
