The Added Value of Tissue or Liquid Biopsy NGS Profiling in Advanced Solid Tumor Treatment Decisions.

Inclusion Criteria: 1. Adult patient (minimum 18 years) able to provide written informed consent for GeNeo 2.0. 2. ECOG Performance status ≤2 3. Patients with advanced solid tumors or primary CNS tumors that are candidates for systemic anticancer therapy and open for enrollment in a potential downstream therapeutic trial. Enrollment in early treatment lines is strongly encouraged Tumor cohorts of breast cancer and lung cancer will be prioritized, with a minimum cap of 100 for each tumor type. Recruitment for all other tumor type cohorts will be capped at a maximum of 40 patients per tumor type. The MTB can decide on prematurely closing or extending tumor type cohorts based on treatment recommendations, clinical trial landscape or downstream treatment options. Enrollment of patients early in the advanced treatment setting will be strongly encouraged. 4. Patients should have archived tissue available from a metastatic (preferred) or primary lesion biopsy for comprehensive profiling. The tissue should not be more than 2 years-old and fixed in 10% neutral buffered formalin. Tumor cell content should be \>20% Exclusion Criteria: 1. Life expectancy of ≤12 weeks according to the local investigator 2. Clinically significant hematopoietic, renal and/or hepatic dysfunction, according to the local investigator, which would make them ineligible for MGTO therapy 3. Patients unwilling to comply with GeNeo 2.0 protocol data collection, data sharing and other study procedures 4. Patients unwilling to provide informed consent and comply with study procedures.
