Drs. Francis and Pagani, et al reported the updated results of IBCSG-led Suppression of Ovarian Function Trial (SOFT) and the Tamoxifen and Exemestane Trial (TEXT). Premenopausal women were randomly assigned to receive 5 years of adjuvant tamoxifen, tamoxifen plus ovarian suppression, or exemestane plus ovarian suppression in SOFT; or to receive 5 years of adjuvant tamoxifen plus ovarian suppression or exemestane plus ovarian suppression in TEXT. Among premenopausal women with early breast cancer, the addition of ovarian suppression to tamoxifen resulted in significantly improved disease-free and overall survival compared with tamoxifen alone. The use of exemestane plus ovarian suppression further reduced recurrence as compared with both tamoxifen alone and tamoxifen plus ovarian suppression.

Professor Dowsett et al developed and validated a simple clinicopathologic tool (Clinical Treatment Score post–5 years [CTS5]) to estimate residual risk of distant recurrence after 5 years of endocrine treatment. The ATAC data set (N = 4,735) was used to create a prognostic score for post–5-year risk of late distant recurrence, and validity of CTS5 (ATAC) was validated in the BIG 1-98 data set (N = 6,711). Results were published in the Journal of Clinical Oncology.

Epud 2018 March 27. [Epub ahead of print] (IBCSG 22-00).

Dr. Munzone et al investigated the occurrence and the prognostic and predictive relationship of a selected number of somatic mutations in triple-negative breast cancer (TNBC) patients having known clinical outcomes treated within the IBCSG Trial 22-00. Mutational analysis was performed with OncoCarta panel v1.0 using Mass Array System. The panel includes 19 genes belonging to different functional pathways as PI3K pathway, receptor tyrosine kinase and cell cycle-metabolic group.  Mutation assessment was successful for 135 patients (49 cases, 86 controls). A manuscript was published in Breast Cancer Research Treatment.

Efficacy of Chemotherapy for ER-Negative and ER-Positive Isolated Locoregional Recurrence of Breast Cancer: Final Analysis of the CALOR Trial. J Clin Oncol. doi: 10.1200/JCO.2017.76.5719. Epub 2018 February 14. [Epub ahead of print] (IBCSG 27-02).

The CALOR trial investigates the effectiveness of chemotherapy (CT) following local therapy for isolated locoregional recurrence (ILRR), which is associated with a high risk of developing breast cancer distant metastases and death. From August 2003 to January 2010, 162 patients were enrolled. Eligible patients were randomized to CT or No-CT, and stratified by prior CT, hormone-receptor (ER, PR) status, and location of ILRR. A report after 5 years median follow-up showed significant benefit of CT for ER-negative ILRR, but further follow-up was required in ER-positive ILRR.

The final analysis of CALOR after 9 years median follow-up confirms that CT benefits patients with resected ER-negative ILRR. Long-term CALOR trial results do not support the use of CT for ER+ ILRR. The final analysis of the trial was displayed during a poster session at ASCO 2017 and a manuscript has now been published in the Journal of Clinical Oncology.

2017

Dr. Lee’s manuscript investigates individual patient data meta-analysis of seven IBCSG Trials (VI–IX and 13–15) investigated the prognostic value of QL scores at several times before and after disease relapse on overall survival. Among 8024 patients enrolled in one of seven randomized controlled trials in early-stage breast cancer, 3247 had a breast cancer relapse after a median follow-up of 12.1 years. Of these, 677 had completed QL indicator assessments within defined windows 1, 2 or 3 months prior to relapse. Cox regression analyses were performed using these assessments and using identical instruments after relapse. Results have been published in Health and Quality of Life Outcomes.

The SOLE trial is a randomized phase III clinical trial that enrolled almost 4,900 postmenopausal women, in 22 countries, with hormone-sensitive, lymph node-positive breast cancer who were breast cancer-free following 4 to 6 years of prior adjuvant endocrine therapy. Patients were randomly assigned to extend endocrine therapy by either taking an additional 5 years of continuous letrozole  or 5 years of intermittent letrozole; taken for the first 9 months during years 1 to 4, and then continuously for 12 months in year 5).  This is the first trial that evaluates a de-escalation of extended adjuvant endocrine therapy. 5 years of intermittent letrozole did not reduce the risk of recurrence of breast cancer compared with taking the aromatase inhibitor treatment continuously for 5 years. The results were presented at the 2017 ASCO Annual Meeting and published online in The Lancet Oncology.

The APHINITY trial randomzed 4,805 patients, 278 from IBCSG, to chemotherapy plus one year of trastuzumab plus placebo or to chemotherapy plus one year of trastuzumab plus pertuzumab, aiming to determine whether the addition of pertuzumab improves invasive disease-free survival (IDFS) in patients with HER2-positive early breast cancer. The patients assigned pertuzumab had significantly improved rates of IDFS, when compared to the patients assigned placebo (3-year rates of iDFS were 94.1% in the pertuzumab group and 93.2% in the placebo group). The results were presented at the 2017 ASCO Annual Meeting and concurrently published in the New England Journal of Medicine.

J Clin Oncol Precis Oncol. doi: 10.1200/PO.17.00009. 2017 October 13. [Epub ahead of print] (BIG 1-98).

Exploratory analysis of 20,464 possible single-gene biomarkers in METABRIC discovery cohort and a confirmatory meta-analysis of ER-positive and ER-negative breast cancer cohorts confirmed better overall survival with high expression of FGD3 mRNA. In BIG 1-98, FGD3 mRNA was associated with freedom from recurrence. FGD3 was previously shown to inhibit cell migration and is regulated by ESR1. FGD3 may be an important clinical biomarker.

In this commentary, Dr. Prue Francis, SOFT Study Co-Chair, reviews trials and meta-analyses of treatments for hormone-responsive early breast cancer, with emphasis on postmenopausal subgroup. In particular, the paper recommends that very young women under age 35 with ER-positive breast cancer have higher risks of recurrence, and the use of ovarian suppression with oral endocrine therapy should be considered.

This investigation was based on archival tumor tissue from 1323 Danish breast cancer patients enrolled in BIG 1-98. The aim was to determine if patients with high levels of expression for the estrogen receptor (ER), progesterone receptor, BCL-2, and IGF-IR, had improved prognosis following adjuvant endocrine therapy. Patients were classified into ER activity groups based on the levels of these biomarkers. The investigation showed that patients with the highest ER activity profile had significantly longer DFS and OS. The authors recommend additional investigations to assess whether the ER activity profile can be used to identify ER-positive, high-risk breast cancer patients who can be spared adjuvant chemotherapy.

Long-term follow-up of the intergroup exemestane study. E-published J Clin Oncol 2017 May 3 (IBCSG 16-98).

This final report of the Intergroup Exemestane Study (IES) presents results after median follow-up of 10 years. Among patients with ER-positive or ER-unknown tumors, the authors reported a modest improvement in overall survival with switching to exemestane vs continuing tamoxifen, after 2-3 years of tamoxifen. The IES and other studies have established the value of a strategy of switching to an AI after 2 to 3 years of tamoxifen to reduce disease recurrence and breast cancer mortality.

Euro J Cancer 79:129-138, 2017 (BIG 1-98) (Journal impact factor 6.029).

This is the first investigation of the translational working group of the AI Overview Group (Trans-AIOG), combining individual patient data from 3 of the randomized trials of AI vs tamoxifen that had centrally-assessed HER2 status, to investigate the predictive value of HER2 status for selection of upfront AI vs. tamoxifen in the first 2-3 years of treatment. 6182 of 8010 BIG 1-98 patients contributed to the analysis. The investigation found a statistically significant HER2-by-treatment interaction, suggesting greater benefit of AI for HER2-negative tumors than for HER2-positive tumors. Yet there was heterogeneity of results between trials, in particular for the smaller group of HER2-positive tumors, and few of these patients received HER2-targeted therapy. Thus the results indicate further research is needed.

In this analysis of the BIG 1-98 trial, patients in the 4-arm cohort (N=6,182) were evaluated to determine the role of cholesterol lowering medications (CLM) in preventing breast cancer recurrences. The analysis relies on the systemic levels of total cholesterol and use of CLMs which were collected at baseline and every six months up to 5.5 years during trial treatment.

Poor prognosis after second locoregional recurrences in the CALOR trial. Ann Surg Oncol 24:398-406, 2017 (IBCSG 27-02) (Journal impact factor 3.151).

The first IBCSG paper of 2017, published in the Annals of Surgical Oncology, was based on the primary database from the CALOR trial. A total of 162 patients who had an isolated locoregional recurrence (ILRR) after primary therapy were randomly assigned to receive chemotherapy or no chemotherapy after resection of ILRR. This research project evaluated second ILRRs, management practices for dealing with ILRR, and hormone receptor status. Second ILRRs represented about one third of all recurrence events after the first ILRR, and all were PR-negative.
