Hematological toxicity of adjuvant portal liver infusion with fluorouracil, mitomycin and heparin.

: Adjuvant perioperative liver infusion chemotherapy with fluorouracil, mitomycin and heparin caused mild but significant myelosuppression in the first two postoperative weeks. This was associated with a slightly increased bleeding tendency. Mortality was not increased. Future trials might combine chemotherapy with hematopoietic growth factors in order to minimize myelosuppression.
