PCDHGA12 and neoplasm: There may be n tumor lesions in one tumor-bearing host; the Fib values of these lesions can be denoted as Fib1, Fib2, Fib3... Fibn, respectively; the volumes of the lesions can be denoted as V1, V2, V3...Vn, respectively; and the total Mte (Mtet) value of these lesions is the sum of each Fib multiplying its related V, which can be expressed by the following Equation (4).
