Topotecan (T) ± sorafenib (S) in platinum-resistant ovarian cancer (PROC): A double-blind placebo-controlled randomized NOGGO–AGO intergroup Trial—TRIAS.

5522Background: Sorafenib (S), a multi TK-inhibitor in combination with topotecan (T), a topoisomerase inhibitor showed preclinical synergistic effects in ovarian cancer but critical toxicity. To a...

Neo-/adjuvant phase III trial to compare intense dose-dense (idd) treatment with EnPC to tailored dose-dense (dt) therapy with dtEC-dtD for patients with high-risk early breast cancer: Results on pathological complete response (pCR) for patients treated within the neoadjuvant setting.

568Background: GAIN-2 compares the effectiveness and safety of a predefined idd regimen (EnPC) vs. a dd regimen with modification of single doses depending on individual hematological and non-hemat...

Tumor-Infiltrating Lymphocytes and Response to Neoadjuvant Chemotherapy With or Without Carboplatin in Human Epidermal Growth Factor Receptor 2–Positive and Triple-Negative Primary Breast Cancers

Purpose Modulation of immunologic interactions in cancer tissue is a promising therapeutic strategy. To investigate the immunogenicity of human epidermal growth factor receptor 2 (HER2) –positive and triple-negative (TN) breast cancers (BCs), we evaluated tumor-infiltrating lymphocytes (TILs) and immunologically relevant genes in the neoadjuvant GeparSixto trial. Patients and Methods GeparSixto investigated the effect of adding carboplatin (Cb) to an anthracycline-plus-taxane combination (PM) on pathologic complete response (pCR). A total of 580 tumors were evaluated before random assignment for stromal TILs and lymphocyte-predominant BC (LPBC). mRNA expression of immune-activating (CXCL9, …

Phase III randomised trial comparing intense dose-dense chemotherapy to tailored dose-dense chemotherapy in high-risk early breast cancer (GAIN-2)

Abstract Background The GAIN-2 trial was designed to identify a superior intense dose-dense (idd) strategy for high-risk patients with early breast cancer. Here, we report an interim analysis, at which the predefined futility boundary was crossed. Patients and methods GAIN-2 was an open-label, randomised, multicentre phase III trial. Two thousand eight hundred and eighty seven patients were randomised 1:1 between three courses each of idd epirubicin (E) 150 mg/m2, nab-paclitaxel (nP) 330 mg/m2 and cyclophosphamide (C) 2000 mg/m2 (iddEnPC) versus four cycles of leucocyte nadir-based tailored and dose-dense EC (dtEC) followed by four cycles of tailored and dose-dense docetaxel (dtD) (dtEC-dtD…

Impact of prognostic factors on long-term outcomes in metastatic breast cancer (MBC) patients (pts) receiving bevacizumab (B) plus paclitaxel as first-line cytotoxic treatment.

e12007 Background: B combined with chemotherapy (CT) significantly improves progression-free survival (PFS) and response rate (RR) vs CT alone in the first-line treatment of HER2-negative MBC. In a...

Sorafenib (SOR) plus docetaxel (DOC) as first-line therapy in patients with HER2-negative metastatic breast cancer (MBC): A randomized, placebo-controlled phase II trial.

1072 Background: Anti-angiogenic therapy with the monoclonal anti-VEGF antibody Bevacizumab (Bev) in combination with chemotherapy increases overall response rates (ORR) and progression free surviv...

Efficacy and Safety of First-Line Bevacizumab (BEV) Combined with Paclitaxel (PAC) According to Age: Subpopulation Analysis of a Large, Multicenter, Non-Interventional Study in Patients (Pts) with HER2-Negative Metastatic Breast Cancer (MBC).

Abstract Background: In three randomized phase III trials (E2100, AVADO, RIBBON-1), the combination of Bev with taxane-based therapy significantly improved PFS and response rate versus taxane alone in HER2-negative MBC. Subpopulation analysis of AVADO suggested that the magnitude of the benefit derived from Bev was similar in older and younger pts (≥65 vs <65 years). To gain further information on the safety and efficacy of first-line Bev–pac in older pts treated in the real-life setting, we conducted a subpopulation analysis of data from an ongoing multicenter non-interventional study initiated after the approval of Bev in Germany. Materials and methods: Pts who had received no prio…
