Glucose enters the CSF from the plasma by 2 mechanisms, diffusion and active transport. The level of CSF glucose is influenced by the concentration and duration of the plasma glucose level. CSF glucose levels are 60-70% of plasma glucose levels. The normal fasting CSF glucose is 40-70 mg/dl. In children the nonfasting reference range is 45-100 mg/dl. The CSF glucose level lags behind the plasma level by 30-90 minutes. An increase in CSF glucose means the patient was hyperglycemic 30 to 90 minutes before and has no special clinical significance. A decreased CSF glucose is seen in:

Study design: Phase 2, open-label, randomized trial of patients (N = 60) with breast cancer (aged ≥ 65 years), who received up to 6 cycles of adjuvant fluorouracil, epirubicin, and cyclophosphamide (FEC). Patients were prospectively randomized to receive primary prophylaxis with Neulasta ® on day 2 of all cycles (n = 31, of which 30 received Neulasta ® in cycle 1) or secondary prophylaxis on day 2 of all cycles after a neutropenic event (n = 29), with no reactive G-CSF support being given in cycle 1. Primary endpoint was the proportion of patients with at least 1 neutropenic event (defined as grade 3* or 4 † neutropenia and fever, an infectious complication requiring the use of systemic anti-infectives, or a dose reduction or delay resulting from hematological toxicity) in cycle 1. Secondary endpoint was the ANC profile during cycle 1. 5

A WBC count can indicate that there is a disease or condition affecting white blood cells, but it cannot determine the underlying cause. Several other tests may be performed at the same time or in follow up to an abnormal result to help make a diagnosis. Some of these additional tests may include a WBC differential , a blood smear review , or in severe conditions, a bone marrow examination . A differential may indicate which type of WBC is low or high while a blood smear and/or bone marrow biopsy can reveal the presence of abnormal and/or immature WBCs.

In a retrospective study of 105 patients with non-small cell lung cancer during a 5-year period, 43 had leukocytosis. In 19 of the 43 patients, no clear cut etiology for the leukocytosis was apparent and it was attributed to the tumor itself. In these 19 patients, absolute neutrophilia was detected in 13, eosinophilia was present in three, and eleven exhibited concomitant thrombocytosis. Tumor-associated leukocytosis occurred predominantly, and eosinophilia exclusively, in patients with large cell pulmonary neoplasms. These results suggest an unusual myeloproliferative stimulus in this type of cancer. It may result from tumor cell production of hemopoietic growth factors such as granulocyte-macrophage colony-stimulating activity; however, additional studies are needed to elucidate the underlying mechanism(s), and to determine whether this is a peculiar characteristic of the cells that comprise large cell undifferentiated carcinoma of the lung.
