title: The use of lithium carbonate to correct leukopenia during cancer treatment.
abstract: Leukopenia is a common complication noted in patients receiving radiotherapy and/or chemotherapy but no effective method has been reported so far to correct this complication. In the field of psychiatry, lithium carbonate used in treating depression has been noted to have induced leukocytosis as a side effect. From July 1985 to December 1987, a total of 111 patients receiving radiotherapy and/or chemotherapy with leukopenia were included in this study. There were sixty nine patients who received lithium carbonate and the remaining forty two patients served as control group were allowed to stop their primary treatment temporarily without medication during their period of leukopenia. For the group given lithium carbonate, 79% of the patients were able to recover their white blood count (WBC) above 3,000/cu.mm. within 5 days and finished their primary treatment smoothly. For the control group, it took them on the average about 11.8 days of rest in order to recover their WBC level to 3,000/cu.mm. and above. Reports in the recent literature indicates that the average toxic level is around 1.5 mEq/l to 2.0 mEq/l. In our study, the average serum lithium level before administration is 0.44 mEq/l, it reached 0.59 mEq/l and 1.08 mEq/l after the fifth and the 10th day of intake respectively. From this laboratory data, obviously no patient reached the toxic level and no side effects were noted clinically. Based on these figures, we can see clearly that lithium carbonate can shorten the period of leukopenia in comparison to the control group which was not given any medication.
