Risk Stratification

Plan

Recommended Workup

(Do not repeat reliable recent studies; reference date reviewed.)

Imaging Recommendation

[low-dose whole-body CT / whole-body MRI / spine/pelvis MRI / FDG PET/CT / no additional imaging indicated]: [Rationale for modality choice or deferral]

Bone Marrow Evaluation

  • Disposition: [indicated now / deferred / already performed]
  • Rationale: [drivers for proceeding or deferring]
  • If proceeding: Request plasma cell clonality, flow cytometry, cytogenetics/FISH, Congo red [if indicated]
  • If already performed: [summary and whether repeat needed]

Surveillance Plan

  • First reassessment: [timeframe]
  • Ongoing interval: [frequency based on risk category]
  • Tests each interval: [CBC, calcium, creatinine, SPEP, serum IFE, FLC; urine studies if indicated]
  • Imaging reassessment: [timeframe and modality if applicable]

Escalation Triggers

  • New or worsening focal bone pain or fracture
  • Rising M-protein or rapidly changing FLC ratio
  • New anemia, creatinine rise, or hypercalcemia
  • Progressive proteinuria, edema, or cardiac symptoms suggesting amyloidosis
  • Constitutional symptoms, lymphadenopathy, or hyperviscosity symptoms

Counseling

[Patient education provided]: (Document explanation of monoclonal protein significance, that precursor conditions are monitored rather than treated, surveillance rationale and limitations. If marrow or imaging recommended, document consent discussion. If not completed, note plan to address at next visit.)

Coordination

  • Communication with referring clinician: [summary and method]
  • Referrals: [nephrology / cardiology / neurology / none] — Indication: [reason]
  • Outside records: [requested / received / pending] — [source and status]
