While prognostic indicators have predominantly focused on tumor-intrinsic features, the BM tumor microenvironment (TME) plays a critical role in disease progression and therapeutic resistance. Here, we present a robust prognostic model derived from transcriptomic profiling of the CD138-negative BM fraction, enabling precise risk stratification of patients undergoing bortezomib-based induction therapy. Using bioinformatic deconvolution and a custom immune-stromal signature matrix, we identified gene expression patterns representative of the MMTME. Through rigorous feature selection and elasticnet penalized Cox regression, we developed the MM-5C model, consisting of five genes (SOX11, METTL11B, C3, RBM10, and HOMEZ), which stratifies patients into biologically distinct risk groups and demonstrates prognostic independence from established cytogenetic and clinical staging systems. This model underscores the pivotal role ofTME components in shaping therapeutic outcomes and offers a scalable, clinically translatable tool for personalized risk stratification. Our findings highlight the necessity of integrating microenvironmental insights into MM prognostication and pave the way for microenvironment-informed therapeutic decision-making.  \nKeywords Multiple myeloma, Tumor microenvironment, CD138-negative, Transcriptomic deconvolution, Prognostic model, Elastic-net Cox regression  \nAbbreviations  \nMM Multiple myeloma  \nBM Bone marrow  \nTME Tumor microenvironment ISS International Staging System  \nR-ISS Revised International Staging System MPSS Myeloma Prognostic Score System LDH Lactate dehydrogenase R Responders  \nNR Non-responders  \nFISH Fluorescence in situ hybridization PFS Progression-free survival  \nSCR Stringent complete response CR Complete response  \nSD Stable disease  \nPD Progressive disease NS Not specified  \n1Department of Mathematics, University of Bari Aldo Moro, Bari, Italy. 2Hematology and Cell Therapy Unit, IRCCSIstituto Tumori “Giovanni Paolo II”, Bari, Italy. 3Seràgnoli Institute of Hematology, IRCCS Azienda OspedalieroUniversitaria di Bologna, Bologna, Italy. 4UOC Genetica Medica, Fondazione IRCCS-Casa Sollievo della Sofferenza, San Giovanni Rotondo, Italy. 5Department of Electrical and Information Engineering (DEI), Polytechnic University of Bari, Bari, Italy. 6Clinical Pathology and Microbiology Unit, Bonomo Hospital, Andria, Italy. 􀀍 email: [grazia.gargano@uniba.it](grazia.gargano@uniba.it)  \n[www. nature.com/scientificreports/](www. nature.com/scientificreports/)  \nMultiple myeloma (MM) is a malignancy of plasma cells derived from terminally differentiated B cells. It is characterized by the clonal proliferation of abnormal plasma cells within the bone marrow (BM) . Over the last decades, the incidence of MM has been steadily increasing1,2, while therapeutic strategies evolved significantly, resulting in remarkable improvement of patient survival1,3. However, MM remains largely incurable, with considerable disease-related mortality4. Well-accepted prognostic factors predominantly rely on tumor-intrinsic features such as cytogenetic abnormalities, tumor burden, and clinical stage5–7, although significant efforts have been devoted to refining new prognostic models.
