This study is a joint study of the German Breast Group (GBG) and the Arbeitsgemeinschaft Gynäkologische Onkologie Breast (AGO-B). Background: Combining immune-checkpoint inhibitors with chemotherapy yielded an increased response rates in patients with metastatic triple-negative breast cancer (TNBC). Therefore, we evaluated the addition of durvalumab to standard neoadjuvant chemotherapy (NACT) in primary TNBC. Patients and methods: GeparNuevo is a randomised phase II double-blind placebo-controlled study randomising patients with TNBC to durvalumab or placebo given every 4 weeks in addition to nab-paclitaxel followed by standard EC. In the windowphase durvalumab/placebo alone was given 2 weeks before start of nab-paclitaxel. Randomisation was stratified by stromal tumour-infiltrating lymphocyte (sTILs). Patients with primary cT1b-cT4a-d disease, centrally confirmed TNBC and sTILs were included. Primary objective was pathological complete response (pCR) (ypT0 ypN0). Results: A total of 174 patients were randomised, 117 participated in the window-phase. Median age was 49.5 years (range 23-76); 47 patients (27%) were younger than 40 years; 113 (65%) had stage !IIA disease, 25 (14%) high sTILs, 138 of 158 (87%) were PD-L1-positive. pCR rate with durvalumab was 53.4% (95% CI 42.5% to 61.4%) versus placebo 44.2% (95% CI 33.5% to 55.3%; unadjusted continuity corrected v 2 P ¼ 0.287), corresponding to OR ¼ 1.45 (95% CI 0.80-2.63, unadjusted Wald P ¼ 0.224). Durvalumab effect was seen only in the window cohort (pCR 61.0% versus 41.4%, OR ¼ 2.22, 95% CI 1.06-4.64, P ¼ 0.035; interaction P ¼ 0.048). In both arms, significantly increased pCR (P < 0.01) were observed with higher sTILs. There was a trend for increased pCR rates in PD-L1-positive tumours, which was significant for PD-L1-tumour cell in durvalumab (P ¼ 0.045) and for PD-L1-immune cell in placebo arm (P ¼ 0.040). The most common immune-related adverse events were thyroid dysfunction any grade in 47%.

Overview Venous thromboembolism (VTE) is a common and life-threatening condition in patients with cancer. 1,2 Results from a retrospective study of hospitalized adult patients with cancer with neutropenia (N=66,106) showed that approximately 3% to 12% of these patients, depending on the type of malig-nancy, experienced VTE during their first hospitalization. 1 In a recent health claims database analysis of patients undergoing chemotherapy for solid tumors in the ambulatory setting (N=17,284), VTE Abstract Venous thromboembolism (VTE) remains a common and life-threatening complication among patients with cancer. Thromboprophylaxis can be used to prevent the occurrence of VTE in patients with cancer who are considered at high risk for developing this complication. Therefore, it is critical to recognize the various risk factors for VTE in patients with cancer. Risk assessment tools are available to help identify patients for whom discussions regarding the potential benefits and risks of thromboprophylaxis would be appropriate. The NCCN Clinical Practice Guidelines in Oncology for VTE provide recommendations on risk evaluation, diagnosis, prevention , and treatment of VTE in patients with cancer. (JNCCN

PURPOSE The GeparSepto trial demonstrated that weekly nanoparticle albumin-bound (NAB)–paclitaxel significantly improves the pathologic complete remission rate compared with weekly solvent-based (sb) paclitaxel followed by epirubicin plus cyclophosphamide as neoadjuvant treatment in patients with primary breast cancer (BC). Here, we report data on long-term outcomes. METHODS Patients with histologically confirmed primary BC were randomly assigned in a 1:1 ratio to 12 times weekly NAB-paclitaxel 150 mg/m2 (after study amendment, 125 mg/m2) or weekly sb-paclitaxel 80 mg/m2 followed in both arms by four times epirubicin 90 mg/m2 plus cyclophosphamide 600 mg/m2 every 3 weeks. Patients with human epidermal growth factor receptor 2 (HER2)-positive BC received dual antibody treatment with trastuzumab (8 mg/kg loading dose followed by 6 mg/kg every 3 weeks) and pertuzumab (840 mg loading dose followed by 420 mg every 3 weeks) concurrently to chemotherapy and continued for 1 year. RESULTS A total of 1,206 patients started treatment, 606 with NAB-paclitaxel and 600 with sb-paclitaxel. After a median follow-up of 49.6 months (range, 0.5 to 64.0 months), 243 invasive disease–free survival (iDFS) events were reported (143 in the sb-paclitaxel and 100 in the NAB-paclitaxel arm). At 4 years, overall patients treated with NAB-paclitaxel had a significantly better iDFS compared with sb-paclitaxel (84.0% v 76.3%; hazard ratio, 0.66; 95% CI, 0.51 to 0.86; P = .002), whereas overall survival did not significantly differ between the two treatment arms (89.7% v 87.2%, respectively; hazard ratio, 0.82; 95% CI, 0.59 to 1.16; P = .260). Long-term follow-up of the treatment-related peripheral sensory neuropathy (PSN) showed a significant decrease of the median time to resolve PSN after NAB-paclitaxel 125 mg/m2 compared with NAB-paclitaxel 150 mg/m2. CONCLUSION The significantly higher pathologic complete response rate with NAB-paclitaxel translated into a significantly improved iDFS in patients with early BC as compared with sb-paclitaxel. PSN improved much faster under NAB-paclitaxel 125 mg/m2 compared with NAB-paclitaxel 150 mg/m2.
