Purpose We compared the efficacy, toxicity, and use of granulocyte colony–stimulating factor (G-CSF) with TAC (docetaxel–doxorubicin–cyclophosphamide) and FEC-D (5-fluorouracil–epirubicin–cyclophosphamide followed by docetaxel) in women less than 50 years of age.Methods The study included all women more than 18 years but less than 50 years of age with her2-negative, node-positive, stage II or III breast cancer diagnosed in Alberta between 2008 and 2012 who received TAC (n = 198) or FEC-D (n = 274).Results The patient groups were well-balanced, except that radiotherapy use was higher in the TAC group (91.9% vs. 79.9%, p < 0.001). At a median follow-up of 49.6 months, disease-free survival was 91.4% for TAC and 92.0% for FEC-D (p = 0.76). Overall survival (OS) was 96% with TAC and 95.3% with FEC-D (p = 0.86).The incidences of grades 3 and 4 toxicities were similar in the two groups (all p > 0.05). Overall, febrile neutropenia (FN) was reported in 11.6% of TAC patients and 15.7% of FEC-D patients (p = 0.26). However, use of G-CSF was higher in the TAC group than in the FEC-D group (96.4% vs. 71.5%, p < 0.001). Hospitalization for FN was required in 10.5% of TAC patients and 13.0% of FEC-D patients (p = 0.41). In G-CSF–supported and –unsupported patients receiving tac, FN occurred at rates of 11.1% and 33.3% respectively (p = 0.08); in patients receiving the FEC portion of FEC-D, those proportions were 2.9% and 8.1% respectively (p = 0.24); and in patients receiving docetaxel after FEC, the proportions were 4.1% and 17.6% respectively (p < 0.001).Conclusions In women less than 50 years of age receiving adjuvant TAC or FEC-D, we observed no differences in efficacy or other nonhematologic toxicities. Based on the timing and rates of FN, use of prophylactic G-CSF should be routine for the docetaxel-containing portion of treatment; however, prophylactic G-CSF could potentially be avoided during the FEC portion of FEC-D treatment.

Abstract Purpose: It is important to continually reevaluate the risk/benefit calculus of internal mammary node irradiation (IMNI) in the era of modern systemic therapy. We aimed to investigate the effect of IMNI on survival in node-positive breast cancer treated with mastectomy and anthracycline plus taxane-based chemotherapy.Methods and Materials: We analyzed 348 patients who underwent mastectomy and anthracycline plus taxane-based chemotherapy for node-positive breast cancer between January 2006 and December 2011. All patients received adjuvant radiotherapy with IMNI (n = 105, 30.2%) or without IMNI (n = 243, 69.8%). The benefit of IMNI for disease-free survival (DFS) and overall survival (OS) was evaluated using multivariate analysis and inverse probability of treatment weighting (IPTW) to adjust for unbalanced covariates between the groups.Results: After a median follow-up of 95 months, the 10-year locoregional recurrence-free survival rate, DFS, and OS in all patients were 94.8%, 77.4%, and 86.2%, respectively. The IPTW-adjusted hazard ratio (HR) for the association of IMNI (vs. no IMNI) with DFS and OS was 0.208 (95% confidence intervals (CI) 0.045–0.966) and 0.460 (95% CI, 0.220-0.962). In multivariate analysis, IMNI was a favorable factor for DFS (HR, 0.458; p = 0.021) and OS (HR 0.233, p = 0.018).Conclusions: IMNI was associated with improved DFS and OS in node-positive patients treated with mastectomy, post-mastectomy radiation therapy, and taxane-based chemotherapy, although the rate of locoregional recurrence was low.

Introduction: Most patients with HER2-positive breast cancer receive chemotherapy and trastuzumab. Data from adjuvant trials have shown that the combination of docetaxel, carboplatin and weekly trastuzumab (TCH) is well tolerated and as effective as anthracycline-containing regimes. Previous investigations on neoadjuvant treatment with taxanes, platinum salts and trastuzumab showed pathological complete remission (pCR) rates between 43.3 and 76%. To date, the longest published follow-up in this indication is 3 years. Here we present 4-year follow-up data for a cohort of 78 patients treated with neoadjuvant TCH. Methods: Between 2009 and 2014 we treated 78 patients with operable HER2-positive breast cancer with a neoadjuvant schedule of docetaxel (75 mg/m2) and carboplatin (AUC 6) every 3 weeks (q3w) and trastuzumab (4 mg/kg loading dose then 2 mg/kg) q1w. Lymph node involvement was verified by sentinel lymph node or core-cut biopsy. Patients were diagnosed at a mean age of 55.5 years; 65.4% had hormone receptor-positive tumors, 34.6% presented with grade 3 disease and 51.3% of patients were node positive. Patients were monitored every 2 cycles by ultrasound. After 6 cycles of chemotherapy all patients had surgery. Axillary dissection was performed in case of positive lymph node status prior to TCH. After surgery, trastuzumab was continued q3w up to 1 year. Results: No grade III/IV toxicities occurred and no case of congestive heart failure was observed. Neither dose modifications nor dose delays were necessary. 34 of the 78 patients (43.6%) achieved a pCR, 27 of the 40 node-positive patients (67.5%) experienced nodal conversion. After a median follow up of 48.5 months the disease-free survival (DFS) was 84.6%, the distant disease-free survival (DDFS) was 87.2% and the overall survival (OS) was 91%. Only T stage and nodal status at baseline were found to be significantly associated with survival estimates. Conclusion: The anthracycline-free regimen TCH is effective and safe in the neoadjuvant therapy of HER2-positive breast cancer, yielding DFS, DDFS and OS probabilities comparable to the results of adjuvant trials. Our data support the use of TCH as a neoadjuvant therapy regimen for patients with HER2-positive breast cancer. They also strongly encourage the use of taxanes and platinum salts as the chemotherapy backbone in studies investigating dual blockade with trastuzumab and pertuzumab in the neoadjuvant setting.

Purpose The primary aim of National Surgical Adjuvant Breast and Bowel Project (NSABP) B-28 was to determine whether four cycles of adjuvant paclitaxel (PTX) after four cycles of adjuvant doxorubicin/cyclophosphamide (AC) will prolong disease-free survival (DFS) and overall survival (OS) compared with four cycles of AC alone in patients with resected operable breast cancer and histologically positive axillary nodes. Patients and Methods Between August 1995 and May 1998, 3,060 patients were randomly assigned (AC, 1,529; AC followed by PTX [AC → PTX], 1,531). Patients ≥ 50 years and those younger than 50 years with estrogen receptor (ER) or progesterone receptor (PR) -positive tumors also received tamoxifen for 5 years, starting with the first dose of AC. Postlumpectomy radiotherapy was mandated. Postmastectomy or regional radiotherapy was prohibited. Median follow-up is 64.6 months. Results The addition of PTX to AC significantly reduced the hazard for DFS event by 17% (relative risk [RR], 0.83; 95% CI, 0.72 to 0.95; P = .006). Five-year DFS was 76% ± 2% for patients randomly assigned to AC → PTX compared with 72% ± 2% for those randomly assigned to AC. Improvement in OS was small and not statistically significant (RR, 0.93; 95% CI, 0.78 to 1.12; P = .46). Five-year OS was 85% ± 2% for both groups. Subset analysis of the effect of paclitaxel according to hormone receptors or tamoxifen administration did not reveal statistically significant interaction (for DFS, P = .30 and P = .44, respectively). Toxicity with the AC → PTX regimen was acceptable for the adjuvant setting. Conclusion The addition of PTX to AC resulted in significant improvement in DFS but no significant improvement in OS with acceptable toxicity. No significant interaction between treatment effect and receptor status or tamoxifen administration was observed.

PURPOSE To compare 1 year of therapy with continuous cyclophosphamide, methotrexate, fluorouracil (5-FU), vincristine, and prednisone (CMFVP) with a short course of treatment with a doxorubicin-based regimen in the postsurgical adjuvant treatment of patients with hormone receptor-negative, node-positive breast cancer. PATIENTS AND METHODS Five-hundred thirty-one eligible women with hormone receptor-negative, node-positive breast cancer were randomized to receive either 1 year of therapy with CMFVP or 20 weeks of therapy with four 5-week courses of treatment with 5-FU, doxorubicin, cyclophosphamide, and methotrexate (FAC-M). RESULTS At a median follow-up time of 4.9 years, the two treatment arms cannot be demonstrated to be different with respect to overall survival (stratified log-rank, P = .27). The 5-year survival rate is 64% on the CMFVP arm and 61% on the FAC-M arm. CMFVP produces marginally superior disease-free survival (P = .06). The estimated 5-year disease-free survival rate is 55% for patients treated with CMFVP as opposed to 50% for patients treated with FAC-M. CONCLUSION Neither regimen was shown to be superior in terms of overall survival. Because the disease-free survival produced by CMFVP is marginally superior to that produced by FAC-M, we do not recommend FAC-M for further investigation or for routine use. Possible implications of this study are discussed in the context of other adjuvant chemotherapy trials.

Purpose Patients with inflammatory breast cancer (IBC) or locally advanced breast cancer (LABC) were randomly assigned to 21-day doxorubicin and cyclophosphamide administered for five cycles (standard arm) versus weekly doxorubicin and daily oral cyclophosphamide administered with granulocyte colony-stimulating factor support for 15 weeks (continuous arm). All patients had subsequent weekly paclitaxel for 12 weeks before surgery. Patients and Methods Patients (n = 372) were randomly assigned to the standard arm (n = 186) or the continuous arm (n = 186) stratified by disease type (LABC, n = 256; IBC, n = 116). The primary outcome was microscopic pathologic complete response (pCR) at surgery. Secondary outcomes included disease-free survival, overall survival, and toxicity. Results More patients in the standard arm had grade 3 to 4 leukopenia and neutropenia, but there were more instances of stomatitis/pharyngitis and hand-foot skin reaction in the continuous arm. Assessed among 356 eligible patients, pCR was not different between the treatment groups stratified by disease type (P = .42). In subset analysis, higher pCR rates were observed in the continuous arm versus the standard arm only for stage IIIB disease (P = .0057) and in IBC (P = .06). Comparison of overall survival and disease-free survival showed no difference between treatment groups (P = .37 and P = .87, respectively). Conclusion No significant clinical benefit was seen for the investigational arm in this trial overall.

512 Background: The joint efficacy analysis of NCCTG N9831 and NSABP B-31 demonstrated improved outcomes with the addition of trastuzumab (H) to doxorubicin and cyclophosphamide (AC) followed by paclitaxel (T) in women with surgically removed HER2- positive breast cancer (NEJM 2005). Following this report, patients randomized to AC→T and less than 6 months from completion of chemotherapy were eligible to receive H. We have updated the initial combined results of these two trials. Methods: Primary and secondary efficacy endpoint were disease free survival (DFS) and overall survival (OS). Cox modeling was performed. Hazard ratios are adjusted for nodal status, tumor size, T schedule, hormone receptor status, and trial (also age for OS). Results: Among the 3,969 women enrolled (ages: 22 to 80yrs), there have been 619 events (H group: 222, non-H: 397). First events were: recurrence (511), contralateral breast disease (18), other second primary cancers (48), and death without recurrence or second primary cancers (42). The median follow-up among the 3,711 women still alive is 2.9 years (range up to 6,4 years). The 4 yr DFS rate and 4 yr OS rate respectively were: 85.9% (95%CI: 84.0–87.8%) and 92.6% (95%CI: 91.2–94.2%) in H group and 73.1% (95%CI: 70.6–75.8%) and 89.4% (95%CI: 87.6–91.2%) in non- H group. Hazard ratio for adjuvant (H/non-H) was 0.49 (P<0.0001; 95%CI: 0.41–0.58) for DFS and 0.63 (P=0.0004; 95%CI: 0.49–0.81) for OS.The rates of a first event per 1,000 women/year during yrs 1–4 were: 26.7, 52.9, 49.6 and 23.2 for H and 42.3, 102.3, 107.6 and 61.5 for non-H. The impact of crossover on clinical outcome will be explored. Conclusions: With an increase in the median follow-up of 11 months and with 225 additional events, the demonstration of substantial improvement in outcomes with the addition of trastuzumab to chemotherapy persist. This improvement continues in spite of some degree of cross-over occurring after the initial results were reported.Updated data regarding crossover outcomes and H duration (as they relate to disease free survival) will be presented.
