The prognostic value of the myeloma-like metastatic pattern was compared with the following markers previously reported to be of prognostic relevance in this patient cohort: the molecular metastasis subtypes MetA, MetB, and MetC; tumour cell proliferation index; PSA and AR IR scores; and KPS [10], [14], [16]. The gene discussed is KLK3; the disease is plasma cell myeloma.
