Summary
Malignancy is rare in low back pain patients. Key indicators for cancer include a prior cancer history, elevated ESR, low hematocrit, and clinician judgment.
Area of Science:
- Oncology
- Diagnostic Accuracy
- Primary Care
Background:
- Low back pain is a common condition with a broad differential diagnosis.
- Malignancy is a rare but serious cause of low back pain.
- Accurate screening tools are essential for early detection.
Purpose of the Study:
- To systematically review the diagnostic accuracy of clinical features and tests for screening malignancy in low back pain patients.
- To identify reliable indicators for malignancy in this population.
Main Methods:
- Systematic review of MEDLINE, EMBASE, and CINAHL databases.
- Inclusion of studies with low back pain cohorts, appropriate reference standards, and diagnostic accuracy data.
- Calculation of positive (LR+) and negative (LR-) likelihood ratios by two independent reviewers.
Main Results:
- Six studies evaluated 22 features/tests; malignancy prevalence ranged from 0.1% to 3.5%.
- Strong predictors of malignancy included prior cancer history (LR+=23.7), elevated ESR (LR+=18.0), reduced hematocrit (LR+=18.2), and clinician judgment (LR+=12.1).
- A combination of age ≥50, prior cancer, weight loss, and lack of improvement yielded 100% sensitivity.
Conclusions:
- Malignancy is an uncommon cause of low back pain.
- Prior cancer history, elevated ESR, reduced hematocrit, and clinician judgment are valuable screening indicators.
- Methodological quality reporting was poor, with limited primary care research.
