Stage I, II, IIIA, and Operable IIIC Breast Cancer

    Also, a systematic review of nine randomized, controlled trials comparing the effectiveness of high-dose chemotherapy and autograft with conventional chemotherapy for women with early poor prognosis breast cancer was performed.[193] In total 1,758 women were randomly assigned to receive high-dose chemotherapy with autograft, and 1,767 women were randomly assigned to receive conventional chemotherapy. There were 48 noncancer-related deaths on the high dose arm and four on the conventional dose arm (RR, 7.74; 95% CI, 3.43–17.50). There was no statistically significant difference in OS between women who received high-dose chemotherapy with autograft and women who received conventional chemotherapy, either at 3 years (RR = 1.02; 95% CI, 0.98–1.06), or at 5 years (RR, 0.98; 95% CI, 0.93–1.05). There was a statistically significant benefit in EFS at 3 years for the group who received high-dose chemotherapy (RR, 1.11; 95% CI, 1.05–1.18). However, this significance was lost at 5 years (RR, 1.00; 95% CI, 0.92–1.08).[193]

    Docetaxel and cyclophosphamide

    The regimen of docetaxel and cyclophosphamide (TC) compared with doxorubicin plus cyclophosphamide (AC) was studied in 1,016 women with stage I or stage II invasive breast cancer. Patients were randomly assigned to receive four cycles of either TC or AC as adjuvant postoperative therapy. At 5 years, DFS was statistically significantly superior for TC compared with AC (86% vs. 80%, HR, 0.67; 95% CI, 0.50–0.94; P = .015).[196][Level of evidence: 1iiA] At the time of the original report, OS was not statistically significantly improved. However, a 7-year update of results for DFS and OS demonstrated that four cycles of TC was superior to standard AC for both DFS and OS.[197][Level of evidence: 1iiA]. At 7 years, DFS was significantly superior for TC compared with AC (81% vs. 75%, HR, 0.74; 95% CI, 0.56–0.98; P = .033). At 7 years, OS was significantly superior for TC compared with AC (87% vs. 82%, HR, 0.69; 95% CI, 0.50–0.97; P = .032). With TC, patients had fewer cardiotoxic effects but other side effects included more myalgia, arthralgia, edema, and febrile neutropenia compared with AC.
