Summary
Mean platelet volume (MPV) can help detect bone marrow metastasis in solid tumor patients. Lower MPV levels (<7.4 fl) strongly indicate metastasis, aiding clinical decisions.
Area of Science:
- Oncology
- Hematology
- Diagnostic Medicine
Background:
- Bone marrow (BM) metastasis from solid tumors can lead to severe complications.
- Mean platelet volume (MPV) has emerged as a potential biomarker for BM disease in thrombocytopenia diagnosis.
Purpose of the Study:
- To evaluate the diagnostic significance of MPV in identifying bone marrow metastasis in patients with solid tumors.
Main Methods:
- Retrospective analysis of 183 individuals, including 121 patients with solid tumors and 62 healthy controls.
- Comparison of MPV values between patients with confirmed BM metastasis (n=61) and those without (n=60), plus healthy controls (n=62).
Main Results:
- Patients with BM metastasis had a significantly lower mean MPV (7.0 ± 0.8 fl) compared to the control group (8.4 fl, P < 0.001).
- A cut-off MPV of <7.4 fl demonstrated high diagnostic accuracy (82.7% sensitivity, 89.6% specificity) with strong predictive values (85% PPV, 90% NPV).
Conclusions:
- Mean platelet volume is a reliable and accessible marker for assessing the likelihood of bone marrow metastasis in patients with solid tumors.
- MPV can assist clinicians in guiding further diagnostic workup for suspected bone marrow involvement.
