Abstract
Abstract
Purpose: HER2 amplification, TOP2A aberrations and absence of TIMP-1 (Tissue Inhibitor of Metalloproteinase-1) expression in breast carcinomas have been associated with incremental benefit from anthracycline-containing adjuvant chemotherapy in several reports. In the DBCG 89D trial, we demonstrated that the predictive value of these markers improved when they were combined in a profile and the present study was undertaken to validate these findings in NCIC CTG MA.5, a similar but independent clinical trial.
Design: TIMP-1 was examined by immunohistochemistry in archival tumor tissue from 403 of 716 premenopausal high-risk patients with known HER2 and TOP2A status who were randomized to CEF or CMF in the MA.5 trial. Patients were classified according to 2 predefined marker profiles — the HT profile (HER2, TIMP-1) and the 2T profile (TOP2A, TIMP-1) and the statistical analyses were performed as closely as possible to the analytical approach used previously in the MA.5 trial and when analysing the biomarker profiles in the DBCG 89D trial.
Results: 98 (24%) patients had no TIMP-1 staining of tumor cells, 27% were HER2 amplified, and 18% were TOP2A aberrant. 44% of patients were classified as HT responsive (HER2-positive and/or TIMP-1 negative) and 37% as 2T responsive (TOP2A aberrant and/or TIMP-1 negative). There was no heterogeneity in treatment effect of CEF versus CMF according to TIMP-1. In HT responsive patients, CEF was superior to CMF with improved RFS (adjusted HR, 0.64; 95% CI, 0.42 to 0.98) and a borderline-significant improvement in OS (adjusted HR, 0.66; 95% CI, 0.42 to 1.04). A significant HT profile versus treatment interaction was detected for OS (P=0.03). In 2T responsive patients, CEF was superior to CMF with borderline significant improvement in RFS (adjusted HR, 0.67; 95% CI, 0.43 to 1.03), and with improvement in OS (adjusted HR, 0.58; 95% CI, 0.36 to 0.93). A significant 2T profile versus treatment interaction was detected for OS (P=0.01).
Conclusion: In the MA.5 trial, we have validated the HT and 2T profiles as predictors of incremental benefit from anthracycline-containing chemotherapy. The proportion of patients categorized as anthracycline responsive increases from 18–27% using individual markers to 37–44% when combining TIMP-1 with either HER2 or TOP2A. Patients with responsive profiles had a 34–42% relative reduction in mortality when treated with CEF. In contrast, patients with non-responsive profiles (56-63% of patients) had no incremental benefit from CEF compared with CMF. All 3 biomarkers are easily applied in the pathology lab and as such could be used in daily clinical practice to select patients for anthracycline or non-anthracycline containing adjuvant chemotherapy.

Abstract #6072
Background: Tissue Inhibitor of Metalloproteinases-1 (TIMP-1) is a naturally occuring proteinase inhibitor, which inhibits most matrix metalloproteinases. It has previously been reported that high levels of tumor TIMP-1 is associated with lack of clinical benefit from anthracycline based chemotherapy in metastatic breast cancer and preliminary data suggest that this is also true for adjuvant treatment. Plasma TIMP-1 has also been shown to predict response to endocrine therapy in patients with metastatic breast cancer. No data regarding TIMP-1 response to neo-adjuvant treatment exists.
 Material and Methods: NICE (1839IL/0712) is a randomized phase II trial, assigning 144 patients per protocol with primary operable estrogen receptor negative breast cancer and tumor ≥ 2 cm to either four cycles of EC (epirubicin 90 mg/m2 and cyclophosphamide 600 mg/m2) plus placebo or EC plus gefitinib 250 mg daily. The primary endpoint was pCR (no invasive residual) at surgery and secondary endpoints were complete (CR) and overall objective (OR) tumor response rates (CR+PR) assessed by palpation, mammography and ultrasonography (the last prevailed in case of disagreements). Plasma TIMP-1 levels were measured (blinded and in duplicates) before and after preoperative EC using a validated enzyme-linked immunosorbent assay.
 Results: 'pCR was attained by 8/71 patients in the EC + gefitinib group and 8/73 patients in the EC + placebo group, and OR by 50 patients in each treatment group. The addition of gefitinib to pre-operative EC was not associated with any significant benefit, thereby justifying pooling of the 2 groups of patients. TIMP-1 ranged from 55.1 to 519 ng/ml, median 126.8 ng/ml at baseline. Patients who obtained pCR had numeric higher plasma TIMP-1 values than non-responders (155.2ng/ml against 139.9 ng/ml, p=0.35). Dichotomizing patients by the plasma TIMP-1 median showed, that patients with elevated TIMP-1 had a numeric increased likelihood of obtaining pCR and OR: Patients with plasma TIMP-1 above the median had a numeric higher pCR rate (6.6% against 4.4%; odds ratio 1.60, p=0.39), and OR (51.0% against 49.0%; odds ratio 1.20, p=0.61). A small decline in TIMP-1 was observed after four cycles of EC (median difference 4.5, 25% and 75% quartile of -28.6 and 27.9, p=0.85) and the change was nearly the same in responders as in non-responders.
 Conclusion: This study could not demonstrate a predictive role of pre-treatment plasma TIMP-1 in neo-adjuvant chemotherapy for primary breast cancer. A change in plasma levels of TIMP-1 during 4 cycles of EC was not associated with response to the treatment.

Abstract #6042
Background: Randomized trials have in general demonstrated that anthracycline-based chemotherapy prolongs disease-free and overall survival as compared to CMF-based regimens. In the Danish Breast Cancer Cooperative Group (DBCG) 89D randomised trial a 21% improvement in overall survival was observed from substitution of methotrexate in the CMF combination with epirubicin. This suggests that the additional effect of anthracyclines is confined to a subset of the patients. We have previously shown that in vitro grown cancer cells devoid of Tissue Inhibitor of Metalloproteinases-1 (TIMP-1) are more sensitive towards chemotherapy than cells expressing TIMP-1 (Davidsen et al., Br J Cancer, 2005). In addition, we have recently published (Schrohl et al., Clin Cancer Res., 2006), that patients with metastatic breast cancer and high levels of TIMP-1 in their primary tumor tissues, have a significantly reduced likelihood of obtaining an objective response to chemotherapy.
 Purpose: The aim of the present study was to evaluate if Tissue Inhibitor of Metalloproteinses-1 (TIMP-1) tumor cell immunoreactivity could be used to identify a subset of patients who benefits from adjuvant chemotherapy.
 Patients and Methods: Formalin fixed paraffin embedded tissue micro arrays from 647 patients who were enrolled in the Danish Breast Cancer Cooperative Group randomized trial 89D comparing adjuvant CMF versus adjuvant CEF were analysed for tumor cell TIMP-1 immunoreactivity. The primary end-point was invasive disease free survival (IDFS). Immunohistochemistry was performed using the anti-TIMP-1 monoclonal antibody VT7 as described previously (Sørensen et al., J. Hist. Cytochem., 2006) and the slides were scored as + or – for positive immunoreactivity.
 Results: Tumor cell TIMP-1 immunoreactivity was found in 75% of the tumor samples. In the CEF treated patients, individuals with TIMP-1 negative tumors had a significant longer IDFS than patients with TIMP-1 positive tumors (p=0.047). The multivariate Cox regression analysis of IDFS showed that CEF was superior to CMF among patients with TIMP-1 negative tumors (HR: 0.51; 95%CI: 0.31 to 0.84, p=0.008), while no significant difference could be demonstrated among patients with TIMP-1 positive tumors (HR: 0.86; 95%CI: 0.66 to 1.11, p=0.24). However, only a non-significanct trend could be demonstrated between TIMP-1 status and CEF versus CMF (p=0.07 for interaction).
 Conclusion: Lack of TIMP-1 tumor cell immunoreactivity seems to predict a favourable effect of epirubicin containing adjuvant therapy in primary breast cancer. However, an independent study is awaited to validate the potential predictive value of TIMP-1 immunoreactivity.

*Würtz SØ and Klintman M contributed equally, Malström P and Brünner N shares the senior authorship.
 Background. Predictive markers are scarcely represented in breast cancer. TIMP-1 has in a previous study (n = 173) performed in our laboratory been shown to carry predictive information for the response to chemotherapy in metastatic breast cancer as high tumor tissue levels of TIMP-1 were significantly associated with a low objective response rate to treatment with the most frequently used chemotherapeutic drugs (CMF or anthracyclines). The purpose of the present study was to validate these previous results with a new independent patient population.
 Methods. The TIMP-1 level was measured using a validated ELISA in 168 primary tumor extracts from patients with metastatic breast cancer and levels were associated with the objective response to CMF and anthracyclines. Patients were included in the study provided that they had received chemotherapy for their metastatic disease and that frozen tumor tissue as well as data on their objective response to chemotherapy was available.
 Results. The median TIMP-1 level in responders was 17.3 (2.9 – 75.8) ng TIMP-1/mg protein and in non-responders it was 19.6 (0-190.3) ng TIMP-1/mg protein. When analysed as a continuous log-transformed variable, increasing tumor levels of TIMP-1 were associated with a decreasing probability of objective response to CMF or anthracyclines (OR = 1.59, 95% CI: 0.97 – 2.62, p = 0.07). This is very similar to the original study and thus supporting previous data. Next, we used a more clinically relevant approach for analysing the data from the validation study. For this analysis, objective response was scored as complete or partial response versus stable disease lasting at least six months (clinical benefit) versus progressive disease (non-response). This analysis showed that increasing levels of TIMP-1 were associated with a poor clinical benefit rate from chemotherapy (OR = 1.56, 95% CI: 0.98 - 2.51, p=0.06). The original study has not previously been analysed using this endpoint. When performing this analysis, similar results were found (OR = 1.62, 95% CI: 1.06 - 2.48, p = 0.02). Combining the new population and the original population in a pooled analysis (n = 341) using a random effects model showed that high levels of TIMP-1 were highly significantly associated with a poor clinical benefit rate from chemotherapy compared with patients with low levels (OR = 1.59, 95% CI: 1.16 - 2.18, p=0.003).
 Conclusion. The present validation study supports previous findings that primary tumor tissue levels of TIMP-1 carries predictive information in metastatic breast cancer treated with chemotherapy.
