Marathon of Hope Cancer Centres Network Study for Ontario (MOHCCN-O)

Inclusion Criteria: 1. Patients with histological and/or cytological confirmation of blood or solid tumor malignancies. For tumour types where pre-surgical biopsy is not routinely performed to confirm a pathologic diagnosis of cancer, patients may consent to this protocol, but eligibility must be confirmed after pathology is finalized demonstrating presence of malignancy 2. All patients must be able to satisfy the required minimum data elements for the 15k gold standard cohort through: 1. Already existing data that satisfies the minimal requirements of a gold standard case (refer to Table 1) 2. Have sufficient biospecimens (tumor and/or blood samples) available for more comprehensive molecular and immunophenotypic characterization 3. Patients who do not satisfy the required minimum data elements but would like to participate, maybe requested to donate blood and undergo a fresh biopsy if the archived Formalin-fixed paraffin-embedded (FFPE) samples are not available, or in cases where a fresh tumor biopsy is deemed necessary for molecular profiling. 4. Participating patients must agree to share their anonymized clinical and genomic data Exclusion Criteria: None.
