This is a master observational trial (MOT). Anyone who has been diagnosed with advanced cancer is eligible as long as they are a candidate for treatment. Each patient will receive testing and treatment as determined by patient in consultation with physician. ROOT will proceed in two directions: (1) Validation Cohorts. These patients will demonstrate the ability of the MOT to prospectively collect data using the same protocol and related documents, standardized data elements and processes, and accepted scientific endpoints; and (2) Analysis Cohorts. The modular nature of the study allows collection of RWD ranging from diagnosis only to the full treatment course of the of the patient. Patients are grouped to allow focused data collection or a specific analysis. Analysis cohorts can be created from patients already enrolled in ROOT or be defined prospectively. Because of the ongoing advancements of molecular based oncology, this trial allows a detailed focus on molecular testing as part of any cohort.
Data is reported by the group that is most qualified to provide this information and is proved, at point of care, using standardized data elements and processes. Physicians will report diagnosis, molecular characteristics, staging, disease burden, significant comorbidities, treatment response, and medical decision making. Molecular testing (reports and details) will be requested from testing laboratories. Any diagnostic films will be received digitally from the location the study was performed. Research staff assist in data entry and providing physicians needed data as part of the regular workflow to allow point-of-care reporting.
The Validation Cohorts and Analysis Cohorts may run sequentially or in parallel with each other.

Group/Cohort | Intervention/treatment |
---|---|
Validation Cohort
Patients enrolled into the study to allow validation of a specific element, process, or endpoint. Validation will be done showing concordance with traditional interventional trial standards.
|
Diagnostic Test: Biomarker Testing (L)
Patients who have received biomarker testing that could affect prognosis or treatment decisions. This generally excludes testing done to assist in the diagnosis of disease or histology where there is no treatment implication from this testing.
Other Names:
Drug: Systemic Treatment (T) Patients who have received any treatment as part of their care. This refers to systemic treatment, but also allows other non-drug related interventions such as surgery or radiotherapy as part of the longitudinal care of the patient.
Other Names:
|
Analysis Cohorts
Patient who are enrolled into the study to allow analysis to determine any association, effect, or benefit. Cohorts can be determined prospectively and/or retrospectively for data already collected, Cohorts are identified to highlight collection of information on patients who are already receiving any treatment or testing as determined by the physician and patient independent of this study. Because many analysis cohorts will be determined in patients already enrolled in the study, this group is inclusive of many different sub-groupings or specific analysis cohorts of patients.

Retrospective Chart Review Cohorts
This arm will use retrospective data obtained through systematic chart review on previously seen patients to compare, contrast, or enhance the efforts of the prospective arms. Because most RWD has been traditionally obtained through retrospective methods, this is also considered the "control arm." Data in this arm will be collected without any patient identifiers. This arm is optional.
