PTPRC and melanoma: The number of primary tumors was too small to evaluate meaningfully, but among those 7 primary tumors, the r value for association of Immunotype Score with PTPRC did not reach statistical significance and did not change with different densities of immune cells in Immunotype A (n = 4) primary melanomas or in Immunotype B + C (n = 3) primary tumors (data not shown).
