The Predictive Value of Neutrophil-to-Lymphocyte Ratio for Hodgkin's Lymphoma Diagnosis in Patients with Asymptomatic Cervical Lymphadenopathy.

In patients with asymptomatic cervical lymphadenopathy, the physician often has to choose between evaluation via follow-up or open biopsy. Follow-up evaluation may lead to a delayed diagnosis of lymphoma, while an open biopsy is associated with surgical risks and costs. This dilemma can be avoided using predictive parameters.
