Box plot of serum MCP-1 and IL-8 levels in lung cancer patients and healthy donors. Serum levels of MCP-1 and IL-8 in lung cancer patients with localized cancer (n = 18) and bone metastases (n = 7) and in healthy donors (n = 20) were measured by ELISA. The minimum detectable level of MCP-1 is typically less than 5.0 pg/ml. Statistical significance was determined using Student's t test. *P < .001 compared with healthy donors. †P < .001 compared with the patients with localized cancer. ‡P < .01 compared with the patients with localized cancer. Horizontal lines in the box represent the first, second (the median), and third quartiles; whiskers (vertical lines) represent extension of data up and down.
