Compositions and methods for isolation and use of cfRNA are disclosed. Most preferably the cfRNA includes a patient-and tumor-specific mutation, and/or encodes a gene that is relevant in immune response or immune suppression. The identity and/or quantity of cfRNA can be further used for diagnosis of tumor, monitoring of prognosis of the tumor, monitoring the effectiveness of treatment provided to the patients, evaluating a treatment regime based on a likelihood of success of the treatment regime, and even as discovery tool that allows repeated and non-invasive sampling of a patient. |
