If biopsy/resection of a new lesion or primary tumor and slow freezing of fresh tissue for single cell RNAseq study (as specified in the CLM) is not feasible, the subject is not eligible for the study. All biopsies must be core needle or excisional. Fine needle aspirate is not acceptable. NOTE: The tissue collected from a surgical resection or multiple core biopsies of either a metastatic lesion or primary tumor for the slow freezing of fresh tissue after the patient has signed consent for the study could also be used for collecting the FFPE specimens.
