Is this trial a fit for you?
✓Likely a good fit
Adults over 18 with a confirmed solid malignancy who are about to start chemotherapy or radiation and have not received prior cytotoxic therapy for their current cancer.
✕Probably not a fit
Patients who do not carry clonal hematopoiesis or who do not develop therapy-related risks may have no direct benefit.

What this trial studies
The CH CARE study collects biospecimens and clinical data from adults with solid tumors who plan to receive cytotoxic therapy. Researchers will analyze molecular features to identify high-risk clonal hematopoiesis and its association with therapy-related myeloid neoplasms. The goal is to develop a risk prediction algorithm to identify patients at highest risk and to explore ways to intercept progression from CH to t-MNs. About 5,000 participants are expected to contribute samples such as blood or buccal swabs. This observational study will use collected data to better understand how CH may influence treatment outcomes and long-term risks.
Why it matters
Potential benefit: If successful, the study could lead to a risk prediction tool to guide monitoring and intervention for therapy-related risks.
How similar studies have gone: Prior research has linked clonal hematopoiesis to treatment-related risks, but this study aims to develop a predictive tool specifically for solid-cancer patients undergoing cytotoxic therapy.

Inclusion Criteria: * Participants to be included in this study include the following: * Adults age \>18 years * Diagnosed with solid malignancy (breast, ovarian, lung, gastric, colorectal, esophageal, uterine, head and neck, or sarcoma cancers) * Have a pending plan to receive chemotherapy or radiation for their solid malignancy (cancer). * Has not received cytotoxic chemotherapy or radiation for their solid cancer diagnosis in the past. Exclusion Criteria: * Individuals without plans for cytotoxic chemotherapy, radiation or PARP inhibitor exposure * Individuals who have received prior chemotherapy and or radiation for their current solid malignancy (cancer) * Individuals with any prior history of blood cancer (leukemia, myelodysplastic syndrome, lymphoma, multiple myeloma, including smoldering multiple myeloma). Persons with blood cancer precursors including clonal hematopoiesis of indeterminate potential (CHIP), clonal cytopenia of uncertain significance (CCUS), monoclonal B lymphocytosis (MBL), monoclonal gammopathy of uncertain significance (MGUS) are eligible for study participation.
