    Summary
    This summary is machine-generated.

    Detecting cancer spread to bone marrow is crucial. Key indicators include specific blood patterns, elevated lactic dehydrogenase, low platelet counts, and bone pain, aiding early identification of metastatic disease.

    Area of Science:

    • Oncology
    • Hematology

    Background:

    • Metastasis to bone marrow is a significant clinical finding, often presenting asymptomatically.
    • Accurate identification of bone marrow involvement is vital for patient management.

    Purpose of the Study:

    • To identify clinical and laboratory variables that correlate with the presence of metastatic carcinoma in bone marrow.
    • To develop a predictive model for bone marrow involvement in cancer patients.

    Main Methods:

    • Retrospective analysis of 103 patients with confirmed bone marrow metastasis and 66 controls with negative biopsies.
    • Stepwise discriminant analysis was employed to evaluate multiple clinical and laboratory parameters.

    Main Results:

    • Strongly correlated parameters for marrow involvement: leukoerythroblastic blood pattern, serum lactic dehydrogenase > 500 IU/L, platelet count < 100,000/µL, and bone pain.

  • Moderately correlated parameters: positive bone scan, hematocrit < 30%, uric acid > 10 mg/dL, and blood urea nitrogen > 25 mg/dL.

    • Conclusions:

    • A combination of specific clinical and laboratory findings can significantly increase the probability of detecting bone marrow metastasis.
    • These data assist clinicians in identifying cancer patients at high risk for bone marrow involvement.
