Periostitis associated with myelofibrosis.

Two patients with myelofibrosis developed fever, leg pain and periostitis. The first patient had myelofibrosis with myeloid metaplasia and was symptomatic for months before x-rays showed periosteal new bone formation in the lower extremities. He subsequently developed periostitis of both upper extremities. Radiation of the lower extremities resulted in significant pain relief. The second patient had a past history of polycythemia vera and experienced painful periostitis of the tibiae and fibulae. 99mTechnetium pyrophosphate bone scans showed increased uptake in the involved bones in both patients. Asymptomatic or painful periostitis may be related to the increased bone blood flow associated with myelofibrosis. Radiation can afford successful palliation in the severely symptomatic patient.

Treatment of advanced colorectal cancer with methyl-CCNU plus 5-day 5-fluorouracil infusion.

Thirty-six patients with advanced colorectal carcinoma who had not received prior chemotherapy and had tumor sites measurable or evaluable for response received methyl-CCNU at a dose of 175 mg/m2 orally on Day 1 plus 5-fluorouracil at a dose of 30 mg/kg/24 hours by continuous iv infusion for 120 hours (Days 1-5). Doses were chosen to approach the maximum which could be administered in combination. The cycle was repeated 6 weeks later. Objective partial responses occurred in six patients (17%), with five responses apparent after the first cycle and one additional response after the second cycle. The response duration ranged from 1.5 to 18+ months (median, 5 months). Dose-limiting toxic effects included mucositis in 18 patients (50%) and dermatitis in nine patients (25%), while leukopenia (less than 4000 cells/mm3) and thrombocytopenia (less than 100,000 platelets/mm3) were observed on at least one occasion during therapy in 52% and 46% of patients, respectively. 5-Fluorouracil administration by infusion avoided overlapping myelosuppression and allowed a higher total dose to be given with methyl-CCNU. However, the response to the combination did not exceed the results anticipated for the use of either drug alone.
