RecruitingProcedureTumor Cell and DNA Detection in the Blood, Urine and Bone Marrow of Patients With Solid CancersPatients with resectable solid primary cancers and even limited number of metastases are potentially curable. However, most patients develop recurrences despite surgery. Circulating and disseminated tumor cell (CTC/DTC) and circulating cell-free (cf) DNA isolation from the blood, urine and bone marrow will increase understanding of cancer spread and advance knowledge to develop individualized therapies.
