Background. We report our experience with vinorelbine, a widely used chemotherapeutic, in unselected metastatic breast cancer patients treated in clinical routine. Patients and Methods. The data of all patients with metastatic breast cancer receiving vinorelbine with or without trastuzumab during a six year period were reviewed. Patients received vinorelbine intravenous 25–30 mg/m2 or 60–80 mg/m2 orally in days 1 and 8 of a 21 day cycle. Results. Eighty-seven women were included. Sixty-two patients received vinorelbine alone and 25 patients received vinorelbine in combination with trastuzumab. In 67 patients this was the first line treatment for metastatic disease and in 20 patients it was 2nd or later line of treatment. The median TTP was six months (range: 1–45). The median overall survival was 11.5 months (range: 1–83). Seventy patients were evaluable for response. In patients receiving first line treatment 44.4% had a response while in the second and subsequent lines setting 12.5% of patients responded (P=0.001). Objective response was obtained in 63.6% of patients receiving concomitant trastuzumab and in 25% of patients receiving vinorelbine alone (P=0.0002). Conclusion. This study confirms a high disease control rate. Response rate and TTP were superior in first line treatment compared to subsequent lines.

10735 Background: Gemcitabine (GEM) has shown efficacy in metastatic breast cancer (MBC). We conducted studies with GEM-based regimens to assess the efficacy and toxicity of GEM combined with other drugs in MBC. GEM was combined with docetaxel (DXL) in pre-treated MBC with an anthracycline-based regimen and GEM was combined with doxorubicin (DXR) in chemonaive patients (pts) with MBC. The studies’ objectives were to show clinically relevant hematologic toxicity and response rates among pts treated with GEM-DXL either in combination in pre-treated pts with anthracycline regimen or GEM-DXR in chemonaive pts with MBC to assess the efficacy of GEM in MBC either in neoadjuvant or first-line treatment. Methods: For GEM-DXL: 42 pts were enrolled; GEM: 1250 mg /m2 D1 & D8, DXL: 75 mg /m2 D1, every 21 days with classical premedication for DXL. For GEM-DXR: 51 pts were enrolled; GEM: 1250 mg /m2 D1 & D 8, DXR: 25 mg/m2 D1 & D8, every 21 days. Results: See table below. In the GEM-DXR group, surgery was performed in 30 pts, and 13 (43.2%) had histologically complete response. The median TTP in this group was 13.3 months (range, 2–53). Conclusions: GEM in MBC is very efficient and produced an interesting objective response and clinical benefit. This activity is consistent in either chemonaive pts or in pts with relapsing breast cancer. [Table: see text] No significant financial relationships to disclose.

Purpose This phase III study compared the efficacy and safety of bevacizumab (BV) when combined with several standard chemotherapy regimens versus those regimens alone for first-line treatment of patients with human epidermal growth factor receptor 2–negative metastatic breast cancer. Patients and Methods Patients were randomly assigned in 2:1 ratio to chemotherapy plus BV or chemotherapy plus placebo. Before random assignment, investigators chose capecitabine (Cape; 2,000 mg/m2 for 14 days), taxane (Tax) -based (nab-paclitaxel 260 mg/m2, docetaxel 75 or 100 mg/m2), or anthracycline (Anthra) -based (doxorubicin or epirubicin combinations [doxorubicin/cyclophosphamide, epirubicin/cyclophosphamide, fluorouracil/epirubicin/cyclophosphamide, or fluorouracil/doxorubicin/cyclophosphamide]) chemotherapy administered every 3 weeks. BV or placebo was administered at 15 mg/kg every 3 weeks. The primary end point was progression-free survival (PFS). Secondary end points included overall survival (OS), 1-year survival rate, objective response rate, duration of objective response, and safety. Two independently powered cohorts defined by the choice of chemotherapy (Cape patients or pooled Tax/Anthra patients) were analyzed in parallel. Results RIBBON-1 (Regimens in Bevacizumab for Breast Oncology) enrolled 1,237 patients (Cape cohort, n = 615; Tax/Anthra cohort, n = 622). Median PFS was longer for each BV combination (Cape cohort: increased from 5.7 months to 8.6 months; hazard ratio [HR], 0.69; 95% CI, 0.56 to 0.84; log-rank P < .001; and Tax/Anthra cohort: increased from 8.0 months to 9.2 months; HR, 0.64; 95% CI, 0.52 to 0.80; log-rank P < .001). No statistically significant differences in OS between the placebo- and BV-containing arms were observed. Safety was consistent with results of prior BV trials. Conclusion The combination of BV with Cape, Tax, or Anthra improves clinical benefit in terms of increased PFS in first-line treatment of metastatic breast cancer, with a safety profile comparable to prior phase III studies.

<b><i>Background:</i></b> Most patients with HER2-positive metastatic breast cancer (MBC) receive first-line treatment with anti-HER2 agents and have already received anti-HER2 therapy as adjuvant or neoadjuvant therapy in the local setting of their disease presentation. Despite that, they constitute only a minority among clinical trials, and their response to reintroduction to anti-HER2 treatments is inconclusive based upon conflicting studies. We aimed to examine if previous exposure influences the clinical outcome of patients treated with anti-HER2 treatments compared to patients who were naïve to anti-HER2 agents. <b><i>Methods:</i></b> We conducted a retrospective observational study of HER2-positive MBC patients who were treated with trastuzumab and pertuzumab from 2014 to 2018. We collected and analyzed data including patients’ demographic characteristic as well as extracted data of previous treatment regimens and the efficiency of the anti-HER2 therapy measured by response rate (RR), time to tumor progression (TTP), and overall survival (OS). <b><i>Results:</i></b> Eighty patients met the inclusion criteria, 26 (32.5%) of them were previously exposed to anti-HER2 treatments and 54 (67.5%) were not previously exposed to anti-HER2 therapy. No significant differences were detected in RR after 3 months of treatment (<i>p</i> = 0.684). TTP was significantly better among patients with no previous exposure in comparison with patients with previous exposure to anti-HER2 therapy (21 vs. 14 months, <i>p</i> = 0.044) and we noted a trend in better OS (<i>p</i> = 0.056). <b><i>Conclusion:</i></b> Our analysis suggests that previous exposure to anti-HER2 agents might influence the clinical outcome of first-line treatment in metastatic HER2 patients. These findings justify further exploration of the benefit of reintroduction of anti-HER2 treatment enabling the optimal treatment for patients with previous anti-HER2 therapy exposure.

Thirteen patients with untreated metastatic breast cancer received epirubicin 60 mg/m2, paclitaxel 155 mg/m2 (both day 1) and capecitabine 665 mg/m2 twice daily (days 1-14) every 21 days, with intra-patient dose escalation/reduction. Grade 3/4 events were infrequent. Nine patients (69%) achieved an objective response. Median time to progression and overall survival were 6.6 and 23.5 months, respectively.
