A growing knowledge highlights the strong benefit of regular physical activity in the management of breast cancer patients, but few studies have considered biological parameters in their outcomes. In the prospective randomised trial after breast cancer treatment completion “PACThe,” we determined the effects of physical activity and nutritional intervention on the biological and anthropometric status of patients after one year of follow-up, and clarified the link between biomarkers at allocation and disease-free survival. 113 patients from the population of the “PACThe” study (n = 251) were analysed for biological parameters. Patients were randomized after chemotherapy in two arms: the intervention “SPA” receiving a 2-week session of physical training, dietary education, and physiotherapy (n = 57), and the control “CTR” (n = 56). Diet questionnaire, anthropometric measures, and blood parameters were determined at allocation and one year later. Survival and recurrence were checked over 7 years. Data were considered as a function of BMI, i.e., ≤25 for normal, 25–30 for overweight, and >30 for obese patients. At allocation, the large standard deviation for nutrient-intake values reflected an unbalanced diet for some patients in the three groups. At one-year follow-up, we noticed an increase in glucose (p<10−6), insulin (p<10−7), and adiponectin (p<0.022) plasma levels for both intervention arms, which were more accentuated for the >30 groups. Using the Cox model, we demonstrated that the highest testosterone plasma values were linked to an increase of the recurrence risk (HR [CI–95%] = 5.06 [1.66–15.41]; p=0.004). One-year after a global multidisciplinary supportive and educational intervention, we found few anthropometric and biological changes, mainly related to the patient’s initial BMI. We highlighted the importance of plasma testosterone in the evaluation of patient’s recurrence risk. Future studies would help better understand the mechanisms by which such multidisciplinary interventions could interact with breast cancer recurrence and define the most effective modalities.

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.

Purpose Phosphatidylinositol-4, 5-bisphosphate 3-kinase catalytic subunit alpha ( PIK3CA) mutations are frequently observed in primary breast cancer. We evaluated their prognostic relevance by performing a pooled analysis of individual patient data. Patients and Methods Associations between PIK3CA status and clinicopathologic characteristics were tested by applying Cox regression models adjusted for age, tumor size, nodes, grade, estrogen receptor (ER) status, human epidermal growth factor receptor 2 (HER2) status, treatment, and study. Invasive disease-free survival (IDFS) was the primary end point; distant disease-free survival (DDFS) and overall survival (OS) were also assessed, overall and by breast cancer subtypes. Results Data from 10,319 patients from 19 studies were included (median OS follow-up, 6.9 years); 1,787 patients (17%) received chemotherapy, 4,036 (39%) received endocrine monotherapy, 3,583 (35%) received both, and 913 (9%) received none or their treatment was unknown. PIK3CA mutations occurred in 32% of patients, with significant associations with ER positivity, increasing age, lower grade, and smaller size (all P < .001). Prevalence of PIK3CA mutations was 18%, 22%, and 37% in the ER-negative/HER2-negative, HER2-positive, and ER-positive/HER2-negative subtypes, respectively. In univariable analysis, PIK3CA mutations were associated with better IDFS (HR, 0.77; 95% CI, 0.71 to 0.84; P < .001), with evidence for a stronger effect in the first years of follow-up (0 to 5 years: HR, 0.73; 95% CI, 0.66 to 0.81; P < .001; 5 to 10 years: HR, 0.82; 95% CI, 0.68 to 0.99; P = .037); > 10 years: (HR, 1.15; 95% CI, 0.84 to 1.58; P = .38; P heterogeneity = .02). In multivariable analysis, PIK3CA genotype remained significant for improved IDFS ( P = .043), but not for the DDFS and OS end points. Conclusion In this large pooled analysis, PIK3CA mutations were significantly associated with a better IDFS, DDFS, and OS, but had a lesser prognostic effect after adjustment for other prognostic factors.

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.

Breast cancer is the most prevalent female malignancy. When diagnosed at young age (up to 40 years), negative clinical, morphological and prognostic features are noted. A non-randomized retrospective trial (n=500) was performed to evaluate different scenarios of breast cancer hormone therapy in young patients. Ovarian suppression in young patients is shown to statistically improve prognosis. Disease-free survival rate values are observed to decrease in patients without ovarian suppression in comparison with any type of ovarian suppression, especially at a remote follow-up (after 60 months). Menstrual function resumption and no amenorrhea after chemotherapy significantly decrease disease-free survival rate values in young patients.

Abstract Backgroud: Longer follow-up was necessary to testify the exact value of mastoscopic axillary lymph node dissection (MALND).Methods：From January 1, 2003 to December 31, 2005,1027 patients with operable breast cancer were randomly assigned to two groups: MALND and CALND. 996 eligible patients were enrolled. The end points are disease free survival and overall survival.Results：The final cohort of 996 patients was followed for an average of 184 months. The distribution of all events was fairly similar between two groups of patients. The incidence of local in-breast events did not differ in a significant manner between two cohorts. Similarly, the rate of distant metastases was not significantly different with 30.0% in MLND and 32.6% in CALND. And no significant difference was observed in other primary tumor between two groups (p=0.46). Patients who remain alive with no event comprise a total of 37.2% in MALND and 35.4% in CALND. Other primary cancers and deaths from other causes were distributed equally between two groups. The 15-year disease-free survival rates were41.1 percent for the MALND group and 39.6 percent for the CALND group (p=0.79). MALND was found to be not inferior for overall survival (P =0.54). The 15-year overall survival rates were 49.5 percentafter MALND and 51.2 percentafter CALND (p=0.86). Probability of overall survival was not significantly different between two groups.Conclusions：MALND does not increase unfavorable events, and also does not affect the long-term survival of patients. Therefore, MALND should be one of the preferred approaches for breast cancer surgery.

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.
