Purpose Luminal breast cancer has a long natural history, with recurrences continuing beyond 10 years after diagnosis. We analyzed long-term follow-up (LTFU) of efficacy outcomes and adverse events in the Breast International Group (BIG) 1-98 study reported after a median follow-up of 12.6 years. Patients and Methods BIG 1-98 is a four-arm, phase III, double-blind, randomized trial comparing adjuvant letrozole versus tamoxifen (either treatment received for 5 years) and their sequences (2 years of one treatment plus 3 years of the other) for postmenopausal women with endocrine-responsive early breast cancer. When pharmaceutical company sponsorship ended at 8.4 years of median follow-up, academic partners initiated an observational, LTFU extension collecting annual data on survival, disease status, and adverse events. Information from Denmark was from the Danish Breast Cancer Cooperative Group Registry. Intention-to-treat analyses are reported. Results Of 8,010 enrolled patients, 4,433 were alive and not withdrawn at an LTFU participating center, and 3,833 (86%) had at least one LTFU report. For the monotherapy comparison of letrozole versus tamoxifen, we found a 9% relative reduction in the hazard of a disease-free survival event with letrozole (hazard ratio [HR], 0.91; 95% CI, 0.81 to 1.01). HRs for other efficacy end points were similar to those for disease-free survival. Efficacy of letrozole versus tamoxifen for contralateral breast cancer varied significantly over time (0- to 5-, 5- to 10-, and > 10-year HRs, 0.62, 0.47, and 1.35, respectively; treatment-by-time interaction P = .005), perhaps reflecting a longer carryover effect of tamoxifen. Reporting of specific long-term adverse events seemed more effective with national registry than with case-record reporting of clinical follow-up. Conclusion Efficacy end points continued to show trends favoring letrozole. Letrozole reduced contralateral breast cancer frequency in the first 10 years, but this reversed beyond 10 years. This study illustrates the value of extended follow-up in trials of luminal breast cancer.

PURPOSE: We conducted a phase II pilot study of dose-intensive adjuvant chemotherapy with doxorubicin followed sequentially by high-dose cyclophosphamide to determine the safety and feasibility of this dose-dense treatment and to estimate the disease-free and overall survival in breast cancer patients with four or more involved axillary lymph nodes. PATIENTS AND METHODS: Seventy-three patients received adjuvant treatment with four cycles of doxorubicin 75 mg/m2 as an intravenous bolus every 21 days, followed by three cycles of cyclophosphamide 3,000 mg/m2 every 14 days with granulocyte colony-stimulating factor support. RESULTS: Seventy-one patients were assessable, and all but two completed all planned chemotherapy. There was no treatment-related mortality. The most common toxicity was neutropenic fever, which occurred in 39% of patients. Median disease-free survival is 66 months (95% confidence interval, 34 to 98 months), and median overall survival has not yet been reached. At 5 years of follow-up, the disease-free survival is 51.7%, and overall survival is 60.0%. There is no long-term treatment-related toxicity, and no cases of acute myelogenous leukemia or myelodysplastic syndrome have been observed. CONCLUSION: Our pilot study of doxorubicin followed by cyclophosphamide demonstrates the safety and feasibility of the sequential dose-dense plan. Long-term follow-up, although noncomparative, is promising. However, this regimen is associated with a higher incidence of toxicity (and also higher costs) than the standard dose and schedule of doxorubicin and cyclophosphamide, and therefore it should not be used as conventional therapy in the absence of demonstrated improvement of outcome. Randomized trials testing the dose-dense approach have been completed but not yet reported. Because the sequential plan can decrease overlapping toxicities, it is an appropriate platform for the addition of newer active agents, such as taxanes or monoclonal antibodies.

e13575 Background: Long-term safety of pregnancy after breast cancer still remained controversial, especially according to tumor subtypes. Prior results of other studies have limitations of short follow-up periods or small groups. Methods: We analyzed a population-based retrospective cohort data extracted from a random sample of 50% of women aged between 20 and 60 years who were diagnosed with breast cancer from 2002 to 2017 in the Korean National Health Insurance Service database. Propensity score matching analysis for age and Charlson Comorbidity Index (CCI) variables was performed for pregnant groups and non-pregnant groups with the same type of hormone therapy, chemotherapy and surgery. Study population was categorized to 4 biologic subgroups by the combination of hormone therapy, chemotherapy and target therapy. In this observational study, 1,566 patients with pregnancy after breast cancer were matched (1:2) to 2,462 non-pregnant patients of similar characteristics, adjusting for guaranteed bias. The matched patients were followed up to 7 years, or disease and mortality occurrence after the diagnosis of breast cancer. Survival estimates were calculated using the Kaplan-Meier analysis, groups were compared with the log-rank test. Results: Mean time from diagnosis to pregnancy was 3.4 years in study population. At a follow-up of 7 years after pregnancy, no inferiority in disease-free survival and overall survival was observed in pregnant patients factoring in treatment bias. In sub-analysis according to tumor subtypes, no difference in disease-free survival was observed between pregnant and non-pregnant patients in HR-positive and triple negative subgroup ( p= 0.088, p= 0.048, respectively). Likewise, no overall survival difference was observed in ER-positive patients and triple negative patients ( p= 0.05∼0.73, p= 0.03∼0.09, respectively). Conclusions: Our observational data provides reassuring evidence on long-term safety of pregnancy in young breast cancer patients, regardless of tumor subtypes.

PURPOSE The GeparSepto trial demonstrated that weekly nanoparticle albumin-bound (NAB)–paclitaxel significantly improves the pathologic complete remission rate compared with weekly solvent-based (sb) paclitaxel followed by epirubicin plus cyclophosphamide as neoadjuvant treatment in patients with primary breast cancer (BC). Here, we report data on long-term outcomes. METHODS Patients with histologically confirmed primary BC were randomly assigned in a 1:1 ratio to 12 times weekly NAB-paclitaxel 150 mg/m2 (after study amendment, 125 mg/m2) or weekly sb-paclitaxel 80 mg/m2 followed in both arms by four times epirubicin 90 mg/m2 plus cyclophosphamide 600 mg/m2 every 3 weeks. Patients with human epidermal growth factor receptor 2 (HER2)-positive BC received dual antibody treatment with trastuzumab (8 mg/kg loading dose followed by 6 mg/kg every 3 weeks) and pertuzumab (840 mg loading dose followed by 420 mg every 3 weeks) concurrently to chemotherapy and continued for 1 year. RESULTS A total of 1,206 patients started treatment, 606 with NAB-paclitaxel and 600 with sb-paclitaxel. After a median follow-up of 49.6 months (range, 0.5 to 64.0 months), 243 invasive disease–free survival (iDFS) events were reported (143 in the sb-paclitaxel and 100 in the NAB-paclitaxel arm). At 4 years, overall patients treated with NAB-paclitaxel had a significantly better iDFS compared with sb-paclitaxel (84.0% v 76.3%; hazard ratio, 0.66; 95% CI, 0.51 to 0.86; P = .002), whereas overall survival did not significantly differ between the two treatment arms (89.7% v 87.2%, respectively; hazard ratio, 0.82; 95% CI, 0.59 to 1.16; P = .260). Long-term follow-up of the treatment-related peripheral sensory neuropathy (PSN) showed a significant decrease of the median time to resolve PSN after NAB-paclitaxel 125 mg/m2 compared with NAB-paclitaxel 150 mg/m2. CONCLUSION The significantly higher pathologic complete response rate with NAB-paclitaxel translated into a significantly improved iDFS in patients with early BC as compared with sb-paclitaxel. PSN improved much faster under NAB-paclitaxel 125 mg/m2 compared with NAB-paclitaxel 150 mg/m2.

Purpose: Improved survival after liver resection for breast cancer liver metastases (BCLM) has been proven; however, there is still controversy on predictive factors influencing outcomes. The analysis of factors related to primary and metastatic cancer eventually influencing long-term outcomes and a review of the literature are presented in this report. Methods: Twenty-seven patients diagnosed with metachronous BCLM between 1996 and 2013 were retrospectively reviewed. Patients who had a minimum disease-free interval between primary tumor and liver metastasis of 12 months, no more than 3 liver lesions, no macroscopic extra-hepatic disease and in which systemic therapy showed a good response were included. Results: Twenty-two patients (82%) were initially diagnosed with a stage I-II disease. Twelve patients presented with multiple liver metastases. The 5 years overall survival (OS) rate was 78%, while the 5 years disease-free survival (DFS) rate was 36%. Initial tumor stage III-IV at first diagnosis and number of metastases >1 was significantly associated with a shorter DFS at multivariate analysis (p = 0.03 and p = 0.04 respectively). Patients with multiple lesions had a median DFS of 15 months compared to 47 months in patients with a single lesion (p = 0.03). Conclusions: Resection of single BCLM from primary stage I-II cancer offers very good long-term survival rates and a low morbidity.
