浆细胞白血病 中国就医指南

Plasma Cell Leukemia (PCL) is a rare and aggressive hematologic malignancy characterized by the clonal proliferation of malignant plasma cells in the peripheral blood, with ≥20% plasma cells or an absolute plasma cell count ≥2 × 10⁹/L. It exists in two forms: primary PCL (de novo, accounting for ~60% of cases) and secondary PCL (evolving from pre-existing multiple myeloma, typically indicating end-stage disease and poorer prognosis). Pathogenetically, PCL arises from genetic instability in terminally differentiated B-lymphocytes, with frequent high-risk cytogenetic abnormalities including del(17p), t(11;14), t(14;16), gain(1q), and hyperdiploidy. Dysregulation of key pathways—such as NF-κB, MAPK, and PI3K/AKT—drives uncontrolled survival, proliferation, and evasion of apoptosis. Bone marrow microenvironment interactions, particularly via CXCR4/CXCL12 and VLA-4/VCAM-1 axes, further promote tumor cell homing, adhesion-mediated drug resistance, and extramedullary dissemination. Epidemiologically, PCL represents <1% of all plasma cell disorders and ~2–4% of all leukemias; incidence is approximately 0.04–0.12 per 100,000 persons annually. Median age at diagnosis is 60–65 years, with a slight male predominance (M:F ≈ 1.3:1). Risk factors include advanced age, prior monoclonal gammopathy of undetermined significance (MGUS) or smoldering multiple myeloma (SMM), exposure to ionizing radiation or certain industrial chemicals (e.g., benzene), and immunosuppression (e.g., post-transplant). Unlike typical multiple myeloma, PCL often presents with rapid-onset systemic symptoms: profound fatigue, recurrent infections (due to hypogammaglobulinemia), bleeding diathesis (thrombocytopenia), renal insufficiency (light-chain cast nephropathy), bone pain (less prominent than in myeloma), and hepatosplenomegaly or lymphadenopathy reflecting extramedullary involvement. Quality of life is severely compromised—patients experience debilitating anemia-related dyspnea and cognitive fog, neuropathic pain from amyloidosis or treatment toxicity, emotional distress linked to poor prognostication (median overall survival: 11–18 months in primary PCL; <6 months in secondary PCL), and significant functional decline requiring caregiver support. Treatment-related toxicities—including cytopenias, neurotoxicity from proteasome inhibitors, and infection risk from immunomodulatory agents—further erode daily functioning, social engagement, and occupational capacity. Early palliative integration, psychosocial support, and symptom-directed care are essential components of comprehensive management.
