The prognostic significance of leukocytosis in cervical cancer.
Cervical cancer is a frequent tumor with established prognostic factors such as FIGO stage and hemoglobin levels among others. Despite the fact that paraneoplastic leukocytosis is relatively common in many solid tumors, only isolated cases of cervical cancer patients presenting this abnormality have been published; hence, the clinical significance of leukocytosis is unknown in this tumor type. Retrospective review on the medical records of 294 consecutive newly diagnosed and untreated locally advanced cervical cancer patients who received radiotherapy and concurrent cisplatin was conducted. Leukocytosis was defined as a persistent white blood cell count exceeding 10,800/microL, determined at least twice before commencing chemoradiation providing that patients were free of any active acute or chronic infection or any other condition known to elevate the leukocyte count. The frequency of leukocytosis and their correlation with clinicopathologic features were investigated, as well as their impact on tumor response and survival. Leukocytosis with a median value of 13,300/microL (11,100-28,800) was observed in 35 (11.9%) patients at diagnosis. Leukocytosis was statistically associated only with advanced stages. Clinical complete response was observed in 57% versus 86% of the patients with and without leukocytosis, respectively. In the univariate analysis, leukocytosis, stage, and hemoglobin levels were significant predictors of survival; however, only leukocytosis and the hemoglobin level remained significant predictors of survival in the multivariate analysis. Leukocytosis is common in cervical cancer patients and has a negative prognostic significance.
