[Safety and tolerance of docetaxel (especially 75 mg/m2) with cyclophosphamide (TC therapy) as adjuvant chemotherapy for Japanese patients with operable breast cancer].

The safety and tolerance of docetaxel (especially 75 mg/m/2) plus cyclophosphamide (600 mg/m2) (TC therapy) as adjuvant chemotherapy for Japanese patients (n=47) with operable breast cancer was evaluated. Among 47 patients who received TC therapy, 38 patients (80.8%) were treated as scheduled for 4 courses every three weeks, and 6 patients (12.8%) were dose-reduced or the interval between courses was extended due to neutropenia or wound infection. Three patients (6.4%) quit TC therapy due to stomatitis or skin toxicities of grade 3. Although febrile neutropenia of grade 3 or 4 was observed in 2 patients (4.3%), TC therapy could be prescribed for these patients. Non-hematological side effects(such as edema, myalgia and arthralgia), occurred in relatively many cases, but were not remarkable. From these results, TC therapy (75/600 mg/m2) is considered to be a safe and tolerable regimen in Japanese patients operated for breast cancer.
