title: Adjuvant chemotherapy and immunotherapy for colorectal cancer: preliminary communication.
abstract: Following surgical resection of Dukes' B or C colorectal cancers 72 patients have been randomly allocated to receive: 5-fluorouracil; or 5-fluorouracil and levamisole; or no treatment. Adjuvant treatment was continued for one year. 66 patients remain evaluable for up to 24 months. Preliminary results show no significant differences in survival or recurrence rates. Two patients receiving 5-fluorouracil and levamisole developed severe, but reversible, neutropenia. Other side effects were uncommon.
