69P - Impact of statin use on survival outcomes of patients with HER2-positive early breast cancer in the APHINITY trial (ID 84)

Abstract

Background

Preclinical data suggest a protective role of statins in patients (pts) with breast cancer. Clinical data are controversial with limited data on the benefit for pts with HER2-positive early breast cancer (HER2+ EBC). We investigated the association of statin use with survival outcomes in pts with HER2+ EBC enrolled in APHINITY (BIG 4-11/NCT01358877).

Methods

APHINITY is a prospective, randomized, double-blind, phase III trial testing the addition of pertuzumab to trastuzumab and chemotherapy in pts with HER2+ EBC. All pts evaluated in APHINITY were included in the present analysis (N=4804). Pts who received statins at baseline, or started statins within one year from randomization were considered as statin users. Pts’ characteristics were compared according to statin use by chi-square test. Survival analysis for invasive-disease-free survival (IDFS), distant relapse-free interval (DRFI), and overall survival (OS) were performed using the Kaplan Meier method and log-rank test. A multivariate analysis using a Cox proportional hazard model was used to generate hazard ratios (HR), adjusting for tumor size, nodal status, hormone receptor status, age, menopausal status, body mass index (BMI) ≥ 30 kg/m2, treatment arm and statin use.

Results

Median follow-up was 6 years. Statin users (N=423) were more frequently ≥65 years old, postmenopausal, obese (BMI ≥ 30 kg/m2) and were treated more often with breast conserving surgery compared to non-statin users (N=4381) (all p<.001). In multivariate analysis, no significant impact of statin use on any of the survival outcomes was observed (IDFS, HR 1.17, 95% confidence interval [CI] 0.86-1.59; DRFI, HR 1.22, 95% CI 0.83-1.79; OS, HR 1.18, 95% CI 0.80-1.72). No significant interaction between statin use, obesity, treatment arm, hormone receptor status and survival could be detected (p>.05).

Conclusions

In this analysis, statin use was not associated with improved survival outcomes in the relatively young EBC population enrolled in APHINITY. We acknowledge the retrospective and exploratory nature of the present analysis. Further research should explore the potential clinical benefit of statins in a higher risk (e.g. older age) EBC population.

113P - Axillary lymph node management in early breast cancer patients with positive sentinel lymph node: a systematic review and meta-analysis of randomized trials. (ID 126)

Abstract

Background

Omitting axillary lymph node dissection (ALND) in patients with early breast cancer and 1 or 2 positive sentinel lymph nodes (SLNs) is still debated especially in those undergoing mastectomy. We aim to provide updated evidence on this topic.

Methods

This is a systematic review and meta-analysis of randomized trials evaluating the omission of ALND in patients with positive SLN. Included studies compared ALND vs. no ALND in breast cancer patients with tumors ≤5 cm and up to 2 metastatic SLNs. In the no ALND group, patients could receive sentinel lymph node dissection (SLND) only or SLND and complementary axillary radiotherapy (SLND + AR). We assessed differences in overall survival (OS), disease free survival (DFS), axillary recurrence rate (ARR) and surgical outcomes (lymphoedema and neuropathy) in ALND vs. SLND alone group and ALND vs. SLND + AR group. Pooled hazard ratios (HRs) and odds ratios (ORs) with 95% confidence intervals (CIs) were calculated using random effects models.

Results

Of 3,638 identified records, 7 (6 studies) were included in our meta-analysis. All six studies were randomized non-inferiority trials with a total of 4789 included patients. Four trials evaluated ALND compared to SLND alone (N=2890). By hypothesizing a non-inferiority margin of 1.25 in survival endpoints, we found that SLND alone is non-inferior to ALND in both OS (HR 0.81, 95% CI 0.62-1.05) and DFS (HR 0.91, 95% CI 0.75-1.09). However, the non-inferiority could not be demonstrated for ARR (HR 1.18, 95% CI 0.64-2.15). Compared to ALND, SLND alone resulted in lower incidence of lymphoedema (OR 0.35, 95% CI 0.15-0.81) but no significant reduction in neuropathy (OR 0.31, 95 CI%, 0.08-1.22).Two trials compared ALND versus SLND + AR (N=1899). In this comparison, the non-inferiority of SLND + AR could not be demonstrated in OS (HR 0.90, 95% CI 0.52-1.58), DFS (HR 0.99, 95% CI 0.66-1.49) and ARR (HR 1.35, 95% CI 0.63-2.89).

Conclusions

SLND is non-inferior compared to ALND in terms of OS and DFS, with lower rates of post-surgical lymphoedema. SLND + AR could be inferior compared to ALND in the survival endpoints evaluated. We were not able to perform subgroup analysis on patients undergoing breast conserving surgery or mastectomy.

177P - Low HER2 expression does not influence prognosis in metastatic triple-negative breast cancer: results from an international, multicenter analysis coordinated by the Austrian Group Medical Tumor Therapy (AGMT) (ID 185)

Abstract

Background

Triple-negative breast cancer (TNBC) is associated with poor prognosis. Therefore, new treatment options are urgently needed. About 35% of triple-negative primary tumors show a low expression of HER2 (HER2-low), a potential target for anti-HER2-drugs currently under investigation. In contrast to early breast cancer, little is known about the frequency and the prognostic value of HER2-low in metastatic TNBC.

Methods

In this international, multicenter analysis, we retrospectively evaluated TNBC patients from five European countries (Austria, France, Italy, Portugal, and Spain). Triple-negativity had to be shown in a metastatic site or in the primary breast tumor diagnosed simultaneously or within 3 years prior to metastatic disease. HER2-low was defined as immunohistochemically (IHC) 1+ or 2+ and lack of HER2 gene amplification measured by in-situ hybridization. HER2-0 was defined as IHC 0+. Univariable survival probabilities were calculated by the Kaplan-Meier method and compared by the log-rank test. Multivariable hazard ratios were estimated by Cox regression models.

Results

In total, 691 patients, diagnosed between Jan/2006 and Feb/2021, were evaluable. The incidence of HER2-low was 32.0% (95%CI 28.5-35.5%), with similar proportions in samples from metastatic sites (n=265; 29.8%; 95%CI 24.3-35.3%) and primary tumors (n=425; 33.4%; 95%CI 28.9-37.9%; P=0.324). Median OS in HER2-low and HER2-0 TNBC was 18.6 months (95% CI 16.5-20.3) and 16.1 months (95% CI 14.5-18.6), respectively, which was not statistically significantly different (HR 1.00; 95%CI 0.83-1.19; P=0.969). Similarly, in multivariable analysis HER2-low had no significant impact on OS (HR 0.95; 95%CI 0.79-1.13; P=0.545). In addition, we did not identify a difference in prognosis between HER2 IHC 0/1+ and IHC 2+ tumors (median OS 16.8 vs. 18.2 months; HR 0.89; 95%CI 0.69-1.17; P=0.414).

Conclusions

In this dataset of metastatic TNBC, the largest published until now, the frequency of HER2-low was 32.0%, which is similar as reported in early TNBC populations. In contrast to the early stages, HER2-low did not influence OS in metastatic TNBC.
