The Impact

PURPOSE: To evaluate the impact of subsequent pregnancy on the prognosis of patients with early breast cancer. PATIENTS AND METHODS: One hundred eight patients who became pregnant after diagnosis of early-stage breast cancer were identified in institutions participating in International Breast Cancer Study Group (IBCSG) studies. Fourteen had relapse of breast cancer before their first subsequent pregnancy. The remaining 94 patients (including eight who relapsed during pregnancy) formed the study group reported here. A comparison group of 188 was obtained by randomly selecting two patients, matched for nodal status, tumor size, age, and year of diagnosis from the IBCSG database, who were free of relapse for at least as long as the time between breast cancer diagnosis and completion of pregnancy for each pregnant patient. Survival comparison used Cox proportional hazards regression models. RESULTS: Overall 5- and 10-year survival percentages (± SE) measured from the diagnosis of early-stage breast cancer among the 94 study group patients were 92% ± 3% and 86% ± 4%, respectively. For the matched comparison group survival was 85% ± 3% at 5 years and 74% ± 4% at 10 years (risk ratio, 0.44; 95% confidence interval, 0.21 to 0.96; P = .04). CONCLUSION: Subsequent pregnancy does not adversely affect the prognosis of early-stage breast cancer. The superior survival seen in this and other controlled series may merely reflect a healthy patient selection bias, but is also consistent with an antitumor effect of the pregnancy.

Purpose This study was performed to characterize the impact of obesity on the risk of breast cancer recurrence and death as a result of breast cancer or other causes in relation to adjuvant treatment. Patients and Methods Information on body mass index (BMI) at diagnosis was available for 18,967 (35%) of 53,816 women treated for early-stage breast cancer in Denmark between 1977 and 2006 with complete follow-up for first events (locoregional recurrences and distant metastases) up to 10 years and for death up to 30 years. Information was available on prognostic factors and adjuvant treatment for all patients. Univariate analyses were used to compare the associations of known prognostic factors and risks of recurrence or death according to BMI categories. Cox proportional hazards regression models were used to assess the influence of BMI after adjusting for other factors. Results Patients with a BMI of 30 kg/m2 or more were older and had more advanced disease at diagnosis compared with patients with a BMI below 25 kg/m2 (P < .001). When data were adjusted for disease characteristics, the risk of developing distant metastases after 10 years was significantly increased by 46%, and the risk of dying as a result of breast cancer after 30 years was significantly increased by 38% for patients with a BMI of 30 kg/m2 or more. BMI had no influence on the risk of locoregional recurrences. Both chemotherapy and endocrine therapy seemed to be less effective after 10 or more years for patients with BMIs greater than 30 kg/m2. Conclusion Obesity is an independent prognostic factor for developing distant metastases and for death as a result of breast cancer; the effects of adjuvant therapy seem to be lost more rapidly in patients with breast cancer and obesity.

e12127 Background: We prospectively investigated the incidence of neutropenic complications (NC) with neo/adjuvant AC (doxorubicin and cyclophosphamide) chemotherapy (CTX) among early-stage breast cancer (ESBC) patients. NC was defined as febrile neutropenia (FN), dose delay/reduction or need of granulocyte colony-stimulating factors (G-CSF) to proceed with CTX. Methods: This was a single-center, observational, prospective cohort study conducted at the McGill University Health Center. All ESBC patients who received AC regimen as neo/adjuvant CTX between February 2016 and February 2017 were included. Hazard ratios (HRs) with 95% confidence intervals (CIs) of predictors of NC were estimated using Cox-proportional hazards models. Results: A total of 118 patients, corresponding to 409 cycles of AC were analyzed. Most patients underwent Q3week cycles (83.1%). Median age was 52 years old (IQR 43-61). Prophylactic G-CSF was given to 20 dose-dense patients and 10 Q3weeks patients. In patients not receiving prophylactic G-CSF, 57 (65.5%) manifested at least one episode of NC (corresponding to an incidence rate of 26.4%/cycle of CTX [95% CI: 20.0%-34.2%]), of which 9 developed FN requiring hospital admission. In the final prediction model, body mass index < 25 kg/m2(HR: 2.36, 95% CI: 1.16-4.78) and increasing glucose levels (HR: 1.56, 95% CI: 1.14-2.14) were significantly associated with NC. Baseline absolute neutrophil count (ANC) was protective. Conclusions: The incidence of NC in our prospective study is significantly higher than previously reported in retrospective studies (26.4% vs. 12%). Normal BMI and high glucose were associated with the highest risk of NC. More importantly, 65% of ESBC on AC will require G-CSF during their treatment due to a NC episode. [Table: see text]

533 Background: Current guidelines define TNBC as complete absence of estrogen (ER) and progesterone receptor (PR), without HER2 amplification. However, the prognostic impact of clinical and histopathological factors, sTILs, and AdjCT in TNBC meeting these strict criteria is unknown. Methods: From a cohort of 9985 women who underwent upfront surgery for M0 breast cancer (BC) at Mayo Clinic Rochester from 1985-2012, 1159 pts with ER negative or low (≤10%) BC were identified for central ER/PR/HER2 staining and HER2 FISH (IHC2+ only) to select those with TNBC by modern definitions. Cox proportional hazards models were used to assess the impact of clinicopathological variables on invasive disease-free (IDFS) and overall survival (OS). Results: Tumors from 605 pts (median age 56.3 yrs) met criteria for TNBC (ER < 1%, PR < 1% and HER2 0, 1 or 2+ and FISH negative). 51% were T1, 65% N0, 88% grade 3, and 75% had Ki67 > 15%. Histologically, 39% were anaplastic, 26% invasive ductal, 16% medullary, 8% metaplastic, 6% apocrine and 5% others. Median sTILs was 20% (0-90%). 55% pts received AdjCT [21% anthracycline (A), 19% A + taxane, and 15% other]. Median follow-up for IDFS and OS were 7.4 and 10.6 yrs, respectively. Multivariate analyses demonstrated that higher N stage (p < 0.01), lower sTILs (p = 0.01) and no AdjCT (p < 0.01) were independently associated with worse IDFS and OS. Histology (medullary subtype) was associated with better IDFS in univariate (HR 0.56, 95% CI, 0.35-0.89) but not in multivariate analyses, once sTILs were accounted for. Among systemically untreated pts (n = 182), higher N (p < 0.01) and lower sTILs (p = 0.04) were associated with worse IDFS. For systemically untreated T1N0 pts (n = 111), the 5-yr IDFS was 70% (95% CI, 61-81) [T1a: 83% (95% CI, 63-100), T1b: 68% (95% CI, 52-88) and T1c: 67% (95% CI, 55-83)], compared to 78% (95% CI, 68-84) for T1N0 pts treated with AdjCT. Conclusions: In TNBC pts, N stage, sTILs and receipt of AdjCT were independently prognostic for IDFS and OS. sTILs remained prognostic for IDFS in systemically untreated TNBC. In N0 TNBC, the risk of recurrence or death was substantial in the absence of chemotherapy, even for those with T1 tumors.

Purpose To determine the association of dietary patterns with cancer recurrence and mortality of early-stage breast cancer survivors. Patients and Methods Patients included 1,901 Life After Cancer Epidemiology Study participants diagnosed with early-stage breast cancer between 1997 and 2000 and recruited primarily from the Kaiser Permanente Northern California Cancer Registry. Diet was assessed at cohort entry using a food frequency questionnaire. Two dietary patterns were identified: prudent (high intakes of fruits, vegetables, whole grains, and poultry) and Western (high intakes of red and processed meats and refined grains). Two hundred sixty-eight breast cancer recurrences and 226 all-cause deaths (128 attributable to breast cancer) were ascertained. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% CIs. Results Increasing adherence to a prudent dietary pattern was associated with a statistically significant decreasing risk of overall death (P trend = .02; HR for highest quartile = 0.57; 95% CI, 0.36 to 0.90) and death from non–breast cancer causes (P trend = .003; HR for highest quartile = 0.35; 95% CI, 0.17 to 0.73). In contrast, increasing consumption of a Western dietary pattern was related to an increasing risk of overall death (P trend = .05) and death from non–breast cancer causes (P = .02). Neither dietary pattern was associated with risk of breast cancer recurrence or death from breast cancer. These observations were generally not modified by physical activity, being overweight, or smoking. Conclusion Women diagnosed with early-stage breast cancer might improve overall prognosis and survival by adopting more healthful dietary patterns.

Objective: To analyze the impact of adjuvant radiotherapy (RT) on ipsilateral breast recurrence (IBR) and overall survival (OS) in patients older than 69 years with early-stage breast cancer. Methods: From January 2007 to June 2015, we analyzed retrospectively 137 women with estrogen receptor–positive T1–2 invasive breast cancer, with negative axillary lymph nodes, dividing them into 2 subgroups: 70 to 79 years and older than 79 years. Results: After a median follow-up of 43.2 months, the 3-year IBR-free survival in patients treated with surgery plus RT was 98.8% and 92.1% in patients treated with surgery alone, with a significant difference ( p = .01). Radiotherapy did not impact overall survival ( p = .10). A higher percentage of patients aged between 70 and 79 years received RT after conservative surgery if compared with the older subgroup ( p < .01). Conclusions: In elderly women, adjuvant RT reduced the IBR, but did not improve OS.

AbstractPurposeTo evaluate the use of exercise in managing fatigue in breast cancer patients undergoing adjuvant radiotherapy. To explore the effectiveness of different exercise practices and explore how optimum management of fatigue might be achieved.MethodA CINAHL (Cumulative Index to Nursing and Allied Health Literature) database search of literature was undertaken and publications screened for retrieval with 24 qualifying for inclusion in the review.ResultsThere is evidence to support various forms of exercise including aerobic, resistance, alternative and combination exercise in the management of fatigue in early stage breast cancer patients undergoing adjuvant radiotherapy. The benefits of exercise for patients with later stage and metastatic disease is less clear and there is a lack of published research related to this category of patient.ConclusionExercise is considered a safe, non-pharmacological intervention for early stage breast cancer patients receiving adjuvant radiotherapy. Further investigation is required into optimum exercise interventions and the effectiveness and viability of supervised and unsupervised models. Patient centred tailored advice and guidance needs to be developed and effectively promoted by therapeutic radiographers in order for patients to fully realise the benefit.
