Adjuvant sequential dose-dense doxorubicin, paclitaxel, and cyclophosphamide (ATC) for high-risk breast cancer is feasible in the community setting.

PURPOSE: This study evaluated the feasibility, when given in the community, of dose-dense, sequential ATC (doxorubicin, paclitaxel, cyclophosphamide) as adjuvant therapy for breast cancer with four or more metastatic axillary lymph nodes. PATIENTS AND METHODS: Patients were recruited after definitive breast cancer surgery if four or more axillary nodes were involved by metastatic cancer and if distant metastases were not present on computed tomographic scan or bone scan. Forty patients received doxorubicin, 90 mg/m2 every 14 days for three cycles; paclitaxel, 250 mg/m2 every 14 days for three cycles; and cyclophosphamide, 3 g/m2 every 14 days for three cycles with filgrastim support. Chemotherapy was administered by the referring physician. RESULTS: Mean dose intensity was 99% for doxorubicin, 96% for paclitaxel, and 99% for cyclophosphamide. Grade 3 toxicities included mucositis (13%), nausea/vomiting (10%), neuropathy (13%), and myalgia/arthralgia (10%). Thirteen patients had neutropenic fever. One patient developed acute leukemia. Three relapses have occurred. Ninety percent of patients are alive and disease-free at a median follow-up of 24 months. DISCUSSION: ATC can be administered in the community at full doses with acceptable toxicity. Preliminary efficacy data suggest that this high-dose, intensively scheduled regimen warrants comparison with standard therapy for high-risk patients.

Sclerosing cholangitis from intraarterial floxuridine.

The development of biliary strictures simulating sclerosing cholangitis is now well-known. We report a patient undergoing intraarterial chemotherapy for metastatic colon cancer of the liver in whom segmental intrahepatic biliary strictures occurred remote from known metastases. The patient remains alive 3-4 years after documented liver metastases with severe progressive portal hypertension, hypersplenism, and fat malabsorption. A table of cases so far reported is given.
