✦ Synopsis

Eighteen surgical patients were studied to determine the effect of anesthesia (general or spinal) and surgery on serum and urinary colony-stimulating factor(s) (CSF). CSF is a leukopoietin that stimulates proliferation of macrophages and granulocytes from bone marrow precursor cells. CSF was assayed by adding aliquots of serum or urine to semisolid agar cultures of bone marrow cells and scoring the number of colonies developing after 7 days of incubation. In all but 1 case, a 3- to 30-fold increase in the 24 hour excretion of urinary CSF was seen on the day of surgery and the first postoperative day. CSF urinary excretion began declining toward normal by the second postoperative day. A parallel increase in granulocyte count, a delayed rise in monocytes, and a decline in absolute lymphocyte counts were also observed. The data suggest that immediately postoperatively there may be a strong stimulus to granulocyte/macrophage proliferation. More rapidly proliferating cells would be anticipated to have increased vulnerability to toxicity from cell cycle-active chemotherapeutic agents.

## Abstract We previously established 2 lung cancer cell lines, OKa‐C‐1 and MI‐4, which constitutively produce an abundant dose of granulocyte‐colony stimulating factor (G‐CSF) and granulocyte macrophage‐colony stimulating factor (GM‐CSF).

GM-CSF is a major regulator of myelopoiesis. Recombinant human GM-CSF (250 micrograms/m2 per day i.v.) was used prior to chemotherapy ("3 + 7" scheme) to recruit leukemic blasts in vivo (de novo AML patients, n = 20) into the chemotherapy sensitive phases of the cell cycle. The stimulatory effect of
