Usefulness of Systemic Computed Tomography (CT) Scanning in the Detection of Malignant Lymphadenopathy [RETRACTED].

摘要

We developed a prediction model to distinguish betweenmalignant and nonmalignant lymphadenopathies. We first analyzedclinical features of 222 patients with lymphadenopathy (161 malignantand 61 nonmalignant) in the derivation group. Through logistic regressionanalysis we identified 6 covariates that independently predict malignancy:age (X1), abdominal lymphadenopathy (X2), lymphadenopathyof the other sites (X3), number of enlarged lymph node regions (X4),absence of fever (X5), and largest lymph node size (X6). We determinedthe formula as follows: predictive score = j2.3 + x1 + 2.8x2 + 1.3x3 +1.6x4 j 2.2x5 + 1.8x6.
