e11505 Background: Our previous study showed the association of AQP5 expression with unfavorable prognosis in patients with early breast cancer (EBC). In addition, we analyzed the prognostic impact of polymorphisms of AQP5 gene in the chromosomal region 12q13 on breast cancer. Methods: The genomic DNA was extracted from paraffin-embedded tumor-free tissue from 609 early breast cancer (EBC) patients underwent curative surgery and then genotyped for 3 polymorphisms (rs3736309, rs1964676, and rs74091167) using the Sequenom Mass array system. Results: The median age of patients was 49 years (range 23-79). 106 (18.2%) patients underwent breast conserving surgery and adjuvant chemotherapy was given to 562 (92.3%) patients. Among enrolled subjects, 447 (73.3%) were hormone-responsive, 94 (15.3%) for HER2 overexpressed, and 98 (16.1%) for triple negative EBC. Among the 3 polymorphisms, AQP5 rs74091167 was significantly associated with disease-free survival (DFS) and distant disease-free survival (DDFS) in a dominant model (P < 0.001 and P = 0.021, respectively). Moreover, multivariate survival analysis revealed that the GG genotype of AQP5 rs74091167 was significantly associated with better DFS (HR = 0.377; 95% CI 0.179-0.793; P = 0.010) when compared with the combine GC/CC genotype adjusted to clinicopathological variables. However, no difference in AQP5 rs74091167 polymorphism was observed based on patient and tumor characteristics. Conclusions: AQP5 rs74091167 variant can be considered as a prognostic marker in patients with EBC after curative operation. In the future, functional relevance of this variant needs to be clarified.

Aim: Adding pertuzumab to standard trastuzumab-based adjuvant therapy significantly improved invasive disease-free survival (IDFS) in the APHINITY trial. However, the magnitude of benefit was marginal in the overall population. Methods: We used GRADE (Grading of Recommendations Assessment, Development and Evaluation) analysis on data from APHINITY to build summary-of-findings tables to evaluate the efficacy, safety and quality of evidence of predefined clinical outcomes for the addition of pertuzumab to trastuzumab-based adjuvant therapy in patients with high-risk HER2-positive early breast cancer. Results: Pertuzumab significantly improved 3-year, event-free, absolute benefit in disease-free survival, IDFS and distant relapse-free interval (DFRI) in patients with node-positive or hormone receptor-negative disease. The analysis provides strength of evidence supporting the addition of pertuzumab in this patient population.

553 Background: In the ZO-FAST trial, postmenopausal women with early breast cancer and a bone mineral density (BMD) T-score ≥ –2 and receiving adjuvant letrozole (2.5 mg/day) were randomized to either immediate ZOL (4 mg/6 months) treatment (upfront ZOL) or to the same therapy but only when BMD T-score decreased to < –2 or fracture occurrence (delayed ZOL). After 60 months, upfront ZOL increased both BMD and disease-free survival (P < .05) relative to delayed ZOL. The present analysis assessed, from a US payer perspective, the cost effectiveness of upfront ZOL vs delayed ZOL in this population. Methods: A Markov state-transition model was developed to estimate the lifetime costs and quality-adjusted life-years (QALYs) for a hypothetical cohort of postmenopausal women with early breast cancer receiving letrozole with upfront or delayed ZOL. Consistent with ZO-FAST, patients were 57 years of age and breast cancer recurrence-free at baseline. Patients could progress over time to Local Recurrence, Contra-lateral Tumor, Distant Recurrence, or Death. Transition probabilities were derived from ZO-FAST, supplemented with literature. Costs and utilities were literature based. All outcomes were discounted 3% per year. Results: Compared to delayed ZOL, upfront ZOL resulted in better overall survival, disease-free survival, and QALYs, but at a higher cost (Table). In the base case, the incremental cost/QALY gained with upfront vs delayed ZOL was $7,967. In > 95% of 1,000 probabilistic sensitivity analysis runs, upfront ZOL costs less than $38,376/QALY gained. Conclusions: Upfront ZOL may increase survival and QALY and, at a cost per QALY well under the $50,000/QALY threshold, is very cost-effective in this population. [Table: see text]

Background: The association between obesity and prognosis in HER2-positive early breast cancer remains unclear, with limited data available. This study aimed to determine the impact of body mass index (BMI) at baseline and weight change after 2 years on outcomes of patients with HER2-positive early breast cancer. Methods: ALTTO was a randomized phase III trial in patients with HER2-positive early breast cancer. BMI was collected at randomization and 2 years after. WHO BMI categories were used: underweight, <18.5 kg/m2; normal weight, 18.5 to <25 kg/m2; overweight, ≥25 to <30 kg/m2; and obese ≥30 kg/m2. A weight change from baseline of ≥5.0% and ≤5.0% was categorized as weight gain and weight loss. The impact of BMI at randomization and of weight change on disease-free survival (DFS), distant disease-free survival (DDFS), and overall survival (OS) were investigated with multivariate analyses, adjusting for baseline patients and tumor characteristics. Results: A total of 8,381 patients were included: 187 (2.2%), 3,797 (45.3%), 2,690 (32.1%), and 1,707 (20.4%) were underweight, normal weight, overweight, and obese at baseline, respectively. Compared with normal weight, being obese at randomization was associated with a significantly worse DDFS (adjusted hazard ratio [aHR], 1.25; 95% CI, 1.04–1.50) and OS (aHR, 1.27; 95% CI, 1.01–1.60), but no significant difference in DFS (aHR, 1.14; 95% CI, 0.97–1.32). Weight loss ≥5.0% at 2 years after randomization was associated with significantly poorer DFS (aHR, 1.34; 95% CI, 1.05–1.71), DDFS (aHR, 1.46; 95% CI, 1.07–1.98), and OS (aHR, 1.83; 95% CI, 1.18–2.84). Hormone receptor and menopausal status but not anti-HER2 treatment type influenced outcomes. Toxicities were more frequent in obese patients. Conclusions: In patients with HER2-positive early breast cancer, obesity at baseline is a poor prognostic factor. Weight loss during treatment and follow-up negatively impacts clinical outcomes. Dietary counseling should be part of survivorship care programs.
