Real-world effect of bevacizumab and eribulin on metastatic breast cancer using a propensity score matching analysis. Mol Clin Oncol 2023; 18:12. [PMID: 36761387 PMCID: PMC9892966 DOI: 10.3892/mco.2023.2608] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2022] [Accepted: 10/27/2022] [Indexed: 01/15/2023] Open
Abstract
Bevacizumab and eribulin are novel agents for the treatment of HER2-negative metastatic breast cancer (MBC); however, the choice between bevacizumab and eribulin for MBC can be difficult. The present study aimed to compare two treatment strategies, eribulin followed by bevacizumab and paclitaxel (BEV + PTX) versus BEV + PTX followed by eribulin, to determine whether the order of administration affects the outcome of MBC in the real world. A total of 180 patients who started BEV + PTX and eribulin treatment for HER2-negative MBC from August 2011 to June 2018 were selected. Of these, 84 patients were treated with both BEV + PTX and eribulin sequentially. To evaluate the influence of the sequential order, the efficacy of BEV + PTX followed by eribulin (B-E arm) was compared to treatment with the reverse sequence (E-B arm). The propensity score matching method (PSMA) was used to improve the robustness of the findings from the present study. A total of 60 cases analyzed received BEV + PTX or eribulin as either first- or second-line treatment. In the entire cohort, the median time to failure of strategy (TFS) was 16.8 and 9.9 months in the B-E and E-B arms, respectively [hazard ratio (HR)=0.515, 95% CI 0.298-0.889, P=0.017). A similar HR was derived from PSMA for TFS. Using PSMA, TFS was 16.9 and 9.9 months in the B-E and E-B arms, respectively (HR=0.491, 95% CI 0.253-0.952, P=0.031). These results suggested that when both bevacizumab and eribulin are administered, bevacizumab should be administered first and eribulin should be administered later to ensure the most effective use of each drug.

Abstract
BACKGROUND Outcomes with and without bevacizumab as first-line chemotherapy in Japanese-only ovarian cancer patients have not been reported. In this study, we report a retrospective study conducted at the Tohoku Gynecologic Cancer Unit. PATIENTS AND METHODS The study included 453 patients with stage III/IV ovarian, fallopian tube, and primary peritoneal cancer who received first-line platinum-based chemotherapy. The patients were divided into two groups: bevacizumab (168 patients) and without bevacizumab (285 patients). The primary endpoint was the rate of platinum-resistant recurrence and the secondary endpoints were the antitumor response, progression-free survival, overall survival, and adverse events. RESULTS The objective response rates for patients with measurable diseases treated with and without bevacizumab were 84.5% and 73.0%, respectively (P = 0.0066). Platinum-resistant recurrence in the groups treated with and without bevacizumab was noted in 31 (18.4%) and 111 (38.6%) patients, respectively (P < 0.0001). The median progression-free survival for the bevacizumab and without bevacizumab groups was 23 and 15 months, respectively (P = 0.0002), and the median overall survival was not reached and 49 months, respectively (P = 0.0005). Hypertension of grade 3 or higher was observed in 21 patients (12.5%) in the bevacizumab group (P < 0.001), and proteinuria was observed in 18 patients (10.7%) and 1 patient (0.3%) in the bevacizumab and without bevacizumab groups, respectively (P < 0.001). Intestinal perforation was observed in only one patient (0.6%) in the bevacizumab group. CONCLUSION Combination and maintenance with bevacizumab in primary chemotherapy for advanced ovarian, fallopian tube, and primary peritoneal cancer was effective in reducing platinum-resistant recurrence rates and prolonging progression-free and overall survival.

Abstract
Background Visceral crisis in metastatic breast cancer (MBC) is defined as severe organ dysfunction requiring rapidly efficacious therapy. Although weekly paclitaxel plus bevacizumab (wPTX + BV) achieves a high response rate in human epidermal growth factor receptor 2 (HER2)-negative MBC, the efficacy and safety of wPTX + BV for visceral crisis is unclear. Methods We retrospectively investigated patients with MBC with visceral crisis who received wPTX + BV. Visceral crisis was defined as follows: liver dysfunction (aspartate or alanine aminotransferase >200 U/L or total bilirubin >1.5 mg/dl), respiratory dysfunction (carcinomatous lymphangiomatosis, SpO2 <93% in ambient air or required thoracentesis), superior vena cava (SVC) syndrome, or bone marrow carcinomatosis. The primary outcome was the proportion of patients on-treatment with wPTX + BV after 12 weeks. We also investigated time to treatment failure (TTF), overall survival (OS), objective response rate (ORR), and adverse events. Results A total of 44 patients with respiratory dysfunction (n = 29), liver dysfunction (n = 10), bone marrow carcinomatosis (n = 7), and SVC syndrome (n = 2) were eligible for this investigation. The proportion of patients on-treatment with wPTX + BV after 12 weeks was 63% (30/44), and the other patients discontinued wPTX + BV because of adverse events (n = 5) and disease progression (n = 9). Median TTF and OS, and the ORR were 131 days and 323 days, and 41%, respectively. No treatment-related death occurred. Conclusion: wPTX + BV achieved favorable efficacy and safety for treating patients with visceral crisis and may therefore be considered an option for the treatment of this acutely severe clinical condition. Visceral crisis is a severe organ dysfunction requiring rapidly efficacious therapy. The efficacy of chemotherapy in visceral crisis is unclear. Weekly paclitaxel plus bevacizumab (wPTX + BV) achieved favorable efficacy and safety. wPTX + BV may be considered an option for breast cancer patients with visceral crisis.

Abstract
BACKGROUND The efficacy of paclitaxel and bevacizumab (PB) compared with other chemotherapies in patients with human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer is unclear. PATIENTS AND METHODS We retrospectively investigated 301 patients with HER2- ABC who received first-line chemotherapy from January 2011 to December 2016. RESULTS We included 114 patients who received PB and 187 patients who received other chemotherapies. After propensity score matching, the PB group showed a significantly superior overall response rate (77.8% vs. 38.9%, p<0.0001) and median time to treatment failure (7.3 vs. 5.9 months, p=0.035). In subgroup analyses, PB improved the median overall survival of patients with pleural lesions or pulmonary lymphangiopathy (not reached vs. 18.9 months, p=0.037), and of patients with three or more metastatic sites without liver metastases, (48.0 vs. 27.3 months, p=0.015). CONCLUSION Compared with conventional chemotherapy, PB improved the overall response rate and time to treatment failure in patients with HER2- advanced breast cancer and improved overall survival in some patient subgroups.

Abstract
BACKGROUND AND PURPOSE Although taxanes are a frequently used group of chemotherapy agents, they can, rarely, lead to macular oedema. The purpose of this article is to review and communicate, in an integrated way, the data of the cases previously reported in the literature, as well as to present a new case. MATERIAL AND METHODS Narrative review of reports of cases of macular oedema associated with taxanes, and communication of the clinical case of a 73-year-old woman who, after treatment with paclitaxel for metastatic breast cancer, developed macular oedema that disappeared after discontinuing the drug. RESULTS The review included 57 cases with data from 109 eyes collected in 52 articles. The large majority (76.79%) of the cases were women, and the mean age was 58.75 years. The cancer that most frequently motivated the treatment was breast cancer (60.72%), and 92.5% of cases had metastases. The most frequently associated drug was paclitaxel (52.63%). The median time to symptom development was 4.25 months. At the initial examination, 92.86% of the cases had bilateral oedema and the mean visual acuity was 0.4 (decimal scale). The mean macular thickness was 509.63 microns, and 97.83% of the eyes had no or minimal angiographic findings. In 90.57% of the cases, the treatment with taxanes was interrupted, and some other treatment was used in 43.86% of the cases, with the most widely used being acetazolamide. The outcome was favourable, to a greater or lesser extent, in 96.23% of cases. CONCLUSIONS Despite being a rare entity, macular oedema associated with the use of taxanes is a disorder that every oncologist and ophthalmologist should be aware of, taking into account the good outcome of the condition that usually occurs when treatment is suspended.

Abstract
Purpose To investigate the effectiveness and safety of bevacizumab–paclitaxel combination therapy as first- or second-line chemotherapy for HER2-negative locally advanced or metastatic breast cancer in daily clinical practice. Methods In this prospective multicenter observational study, bevacizumab–paclitaxel was administered at the discretion of attending physicians. Cohorts A and B had hormone receptor-positive and triple-negative breast cancer (TNBC), respectively. Primary endpoint was overall survival (OS). Multivariate analyses were conducted to identify prognostic factors. Results Between November 2012 and October 2014, 767 patients were enrolled from 155 institutions across Japan. Effectiveness was analyzed in 754 eligible patients (cohort A, 539; cohort B, 215) and safety in 750 treated patients (median observation period, 19.7 months). Median OS (95% CI) was 21.7 (19.8–23.6) months in eligible patients; 25.2 (22.4–27.4) months and 13.2 (11.3–16.6) months in cohorts A and B, respectively; and 24.4 (21.9–27.2) months and 17.6 (15.2–20.0) months in patients receiving first- and second-line therapy, respectively. Factors affecting OS (hazard ratio 95% CI) were TNBC (1.75, 1.44–2.14), second-line therapy (1.35, 1.13–1.63), ECOG performance status ≥ 1 (1.28, 1.04–1.57), taxane-based chemotherapy (0.65, 0.49–0.86), cancer-related symptoms (0.56, 0.46–0.68), and visceral metastasis (0.52, 0.40–0.66). Incidences of grade ≥ 3 AEs hypertension, neutropenia, peripheral neuropathy, proteinuria, and bleeding were 35.7%, 27.2%, 7.2%, 3.7%, and 0.3%, respectively. Conclusions In Japanese clinical practice, combined bevacizumab–paclitaxel was as effective as in previous studies. Factors that independently predicted poor prognosis in the present study are consistent with those identified previously. Trial registration Trial no. UMIN000009086.

Abstract
BACKGROUND To examine the efficacy and safety of induction therapy with paclitaxel and bevacizumab followed by switch maintenance therapy with eribulin (ISMT) in Japanese patients with HER2-negative metastatic breast cancer (MBC). METHODS Patients, who had previously undergone a maximum of 2 regimens of chemotherapy, received 3 cycles of induction therapy with paclitaxel (90 mg/m2 intravenously on days 1, 8, and 15 followed by 1-week drug holiday) and bevacizumab (10 mg/kg intravenously after the completion of paclitaxel administration on days 1 and 15). Patients who had complete response, partial response, or stable disease underwent switch maintenance therapy with eribulin (1.4 mg/m2 intravenously on days 1 and 8 followed by 1-week drug holiday). The primary endpoint was time to treatment failure (TTF) for ISMT. RESULTS Fifty-one eligible patients (median age: 66 years; range: 35-74) were enrolled: 19 (37.3%) and 32 (62.7%) had stage IV and recurrence, respectively, 42 (82.4%) had visceral metastases, and 45 (88.2%) received eribulin-38 of whom showed disease progression, and 40 (78.4%) underwent post therapy. Median TTF was 9.2 months (95% confidence interval [CI]: 7.3-11.1), median progression-free survival was 10.7 months (95% CI: 9.6-11.8), and median overall survival was 20.0 months (95% CI: 16.0-24.0). Relative dose intensity was 97.7% (range: 33.3-100.0) for induction therapy and was 83.3% (range: 49.3-100.6%) for eribulin maintenance therapy. The most common adverse event was alopecia (51 [100%]) in induction therapy and was peripheral sensory neuropathy (37 [82.2%]) in eribulin maintenance therapy. Eribulin was effective with manageable tolerability. CONCLUSIONS ISMT may be a promising therapeutic option for patients with MBC. TRIAL REGISTRATION UMIN000015971 .

Abstract
OBJECTIVE Combined therapy with bevacizumab and paclitaxel (BP regimen) as a first-line treatment has proven highly effective with good tolerance for patients with metastatic breast cancer (MBC). The objective of this study was to examine the efficacy and safety of the BP regimen for Japanese patients with MBC in real-world clinical settings. METHODS From June 2012 through May 2014, we recruited 94 patients at 10 medical institutions. The primary endpoint was time to treatment failure (TTF), and the secondary endpoints were overall survival (OS) and safety. Objective response was assessed according to the Response Evaluation Criteria in Solid Tumors. Adverse events (AEs) were graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0-Japan Clinical Oncology Group. RESULTS Nighty patients with MBC (mean 58 years, range: 34-80 years) were enrolled, and 60 (66.6%) and 52 (57.7%) had undergone prior chemotherapy as adjuvant treatment and treatment for MBC, respectively. Median TTF was 6.2 months (95% confidence interval [CI], 4.2-8.3 months), and median OS was 15.4 months (95% CI, 12.0-18.9 months). The overall response rate was 67.8% (95% CI: 57.1-77.2%). A total of 28 patients (31.1%) required a dose reduction of paclitaxel. Forty-five, 42, and 3 patients received the initial doses of 90, 80, and 60 mg/m2, respectively. Among patients who received the initial doses of 90 mg/m2, 13 patients (28.9%) unexpectedly required a dose reduction of ≥20 mg/m2. The BP regimen was discontinued for 66 (73.3%) of the 90 patients, 52 (57.7%) of whom experienced "disease progression." Grade 3/4 hematologic AEs developed in 51 patients (56.6%), with leukopenia and neutropenia in 16 patients (17.8%) and 21 patients (23.3%), respectively. Grade 3 nonhematologic AEs developed in 8 patients (8.9%), with the most common nonhematologic AE of peripheral neuropathy in 4 patients (4.4%). No Grade 4 nonhematologic AEs developed. Peripheral neuropathy [56 patients (62.2%) ], nail discoloration [53 patients (58.9%) ], and fatigue [51 patients (56.7%) ] were the most predominant AEs-the known AEs of paclitaxel. CONCLUSIONS The BP regimen was active and well tolerated in the real-world clinical settings. As many as 28.9% of patients who received the initial dose of 90 mg/m2 required a dose reduction of paclitaxel by 20 mg/m2. Therefore, there is a need to find a therapeutic regimen that is less likely to result in dose reductions for patients with MBC who undergo a BP regimen using the initial paclitaxel dose of 90 mg/m2.

Abstract
Background Bevacizumab (BEV), a humanized anti-vascular endothelial growth factor (VEGF) monoclonal antibody, enhances the antitumor effectiveness of paclitaxel (PTX)-based chemotherapy in many metastatic cancers. A recent study in mice showed that VEGF receptor inhibitors can interfere with the neuroprotective effects of endogenous VEGF, potentially triggering the exacerbation of PTX-induced neuropathy. In clinical trials, exacerbation of neuropathy in patients who received PTX combined with BEV (PTX+BEV) has generally been explained by increased exposure to PTX owing to the extended duration of chemotherapy. We investigated whether the concurrent use of BEV is associated with the exacerbation of PTX-induced neuropathy. Methods Female patients with breast cancer who had received weekly PTX or PTX+BEV from September 2011 through May 2016 were studied retrospectively. PTX-induced neuropathy was evaluated at the same time points (at the 6th and 12th courses of chemotherapy) in both cohorts. A multivariate Cox proportional-hazards model was used to assess the independent effect of BEV on the time to the onset of neuropathy. Results A total of 107 patients (median age, 55 years; range, 32–83) were studied. Sixty-one patients received PTX as adjuvant chemotherapy, 23 received PTX for metastatic disease, and 23 received PTX+BEV for metastatic disease. Peripheral sensory neuropathy was worse in patients who received PTX+BEV than in those who received PTX alone: at the 6th course, Grade 0/1/2/3 = 4/13/4/0 vs. 25/42/6/0 (P = 0.095); at the 12th course, 2/3/11/3 vs. 7/30/23/2 (P = 0.016). At the 12th course, the incidence of Grade 2 or higher neuropathy was significantly higher in patients treated with PTX+BEV than in those treated with PTX alone (74% vs. 40%; P = 0.017). In multivariate analysis, BEV was significantly associated with an increased risk of neuropathy (HR 2.32, 95% CI 1.21–4.44, P = 0.012). Conclusions The concurrent use of BEV could worsen PTX-induced neuropathy in patients with breast cancer.

A single-arm study evaluating bevacizumab, cisplatin, and paclitaxel followed by single-agent bevacizumab in Japanese patients with advanced cervical cancer. Jpn J Clin Oncol 2016; 47:39-46. [PMID: 27803033 PMCID: PMC5421579 DOI: 10.1093/jjco/hyw143] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2016] [Revised: 09/01/2016] [Accepted: 09/05/2016] [Indexed: 11/14/2022] Open
Abstract
BACKGROUND Adding bevacizumab to chemotherapy for recurrent, persistent or metastatic cervical cancer significantly improved overall survival (primary endpoint), progression-free survival and overall response rate in the randomized Phase III GOG-0240 trial. However, data for bevacizumab-containing therapy are scarce in Japanese patients with advanced cervical cancer. METHODS The primary objective of the single-arm multicenter Phase II JO29569 study was to evaluate the tolerability of paclitaxel (135 mg/m2 over 24 h or 175 mg/m2 over 3 h), cisplatin (50 mg/m2) and bevacizumab (15 mg/kg), administered every 3 weeks until disease progression or unacceptable toxicity in Japanese patients with stage IVB, persistent or recurrent cervical cancer. RESULTS The seven treated patients received a median of nine (range 7-12) bevacizumab cycles and six (range 4-12) chemotherapy cycles. None of the predefined adverse events occurred during the tolerability evaluation period. The most common all-grade adverse events were alopecia, hypertension, decreased appetite, nausea and peripheral sensory neuropathy. There were no cases of fistula. The most common grade ≥3 adverse events were hypertension, neutrophil count decreased and neutropenia. Only one patient experienced febrile neutropenia. The overall response rate was 86% (95% confidence interval, 42-100%), including a complete response in one patient. At data cutoff, disease had progressed in one patient; bevacizumab therapy was ongoing in the remaining six. CONCLUSIONS According to the specified primary objective, a regimen of cisplatin, paclitaxel and bevacizumab was tolerable in Japanese patients and demonstrated encouraging activity in this small single-arm study. Further study is warranted to confirm the safety and effectiveness of bevacizumab in Japanese patients with cervical cancer.

Abstract
To gain consensus on the role of bevacizumab plus paclitaxel as first-line treatment for HER2-negative metastatic breast cancer, a panel of expert oncologists experienced in treating patients with metastatic breast cancer in Italy participated in a Delphi consensus study. The panel reached a full consensus on the efficacy of bevacizumab plus paclitaxel and the clinical meaningfulness of the progression-free survival benefit compared with paclitaxel alone, despite the lack of an overall survival effect in clinical trials. The participants agreed that real-world data support the effectiveness and well-defined safety profile of the regimen. Views on the use of bevacizumab plus paclitaxel in specific patient populations were not unanimous and clinical judgment remains important. Nevertheless, a high level of agreement was reached.

Abstract
We describe a 39-year-old woman with metastatic breast cancer who had grade 4 epistaxis induced by bevacizumab. The patient visited our outpatient clinic with complaints of a lump in her right breast, fatigue, dyspnea, abdominal distention, appetite loss, and weight loss of 10 kg over 1 year. Liver dysfunction was detected, with elevated levels of aspartate aminotransferase (271 IU/L), alanine aminotransferase (100 IU/L), alkaline phosphatase (4,205 IU/L), total bilirubin (2.7 mg/dL), and direct bilirubin (2.1 mg/dL). A secondary liver tumor that occupied most of the liver volume was found, and bone metastasis, ascites, and pleural effusion were also discovered. The Eastern Cooperative Oncology Group performance status was 2. A core needle biopsy of the right breast tumor revealed invasive ductal carcinoma of the breast (nuclear grade 1) that was positive for estrogen receptor and progesterone receptor and negative for human epidermal growth factor receptor 2 overexpression and had a high Ki-67 score. We chose combination chemotherapy with paclitaxel (80 mg/m(2) on days 1, 8, and 15) and bevacizumab (10 mg/kg on days 1 and 15) for 28 days (1 cycle). After completion of the first cycle of chemotherapy, the ascites and pleural effusion decreased, and the metastatic liver tumor shrank. The performance status improved from 2 to 1. On day 3 of the third cycle of chemotherapy, however, she began having persistent epistaxis. On day 6, she lost consciousness and was transported to the emergency room of our hospital. The hemoglobin level was 5.6 g/dL. Blood transfusion and endoscopic hemostasis were immediately started. Bevacizumab was discontinued, and paclitaxel alone was continued; after this change, epistaxis did not recur.

Abstract
BACKGROUND The addition of bevacizumab to paclitaxel or capecitabine has demonstrated improved progression-free survival (PFS) and objective response rate (ORR) as compared with chemotherapy alone in patients with HER2-negative locally recurrent or metastatic breast cancer (LR/MBC). We evaluated the efficacy and safety of first-line therapy of paclitaxel and bevacizumab with or without capecitabine in patients with HER2-negative LR/MBC. METHODS In this multicentre, open-label, randomised phase II trial, women with HER2-negative LR/MBC were randomly assigned in a 1:1 ratio to paclitaxel (90 mg/m2 intravenously [IV] on days 1, 8, and 15) and bevacizumab (10 mg/kg IV on days 1 and 15) every 4 weeks for six cycles, followed by bevacizumab (15 mg/kg IV on day 1) every 3 weeks (AT) or to paclitaxel (90 mg/m2 IV on days 1 and 8), bevacizumab (15 mg/kg IV on day 1) and capecitabine (825 mg/m2 orally twice daily on days 1–14) every 3 weeks for eight cycles, followed by bevacizumab and capecitabine at the same doses every 3 weeks (ATX). The primary end-point was investigator-assessed PFS. Secondary end-points included ORR, duration of response, overall survival (OS) and safety. Exploratory analyses were conducted to evaluate the impact of capecitabine on OS and to validate a novel prognostic model. This trial is registered with EudraCT, number 2006-006058-83. FINDINGS Median PFS was significantly longer in ATX as compared with AT (11.2 months versus 8.4 months; stratified hazard ratio (HR), 0.52; 95% confidence interval (CI), 0.41–0.67; p < 0.0001). The ORR in ATX patients with measurable disease (n = 268) was higher than that in AT (69% versus 51%; p = 0.01). The median duration of response was 6.8 versus 5.4 months for, respectively, ATX and AT (p < 0.0001). Median OS was 24.2 months for ATX and 23.1 months for AT (p = 0.53). The increased rate of grade 3–4 adverse events related to the addition of capecitabine, being hand-foot syndrome (34% versus 0% for AT) and neutropenia (20% versus 12% for AT), generally did not preclude continuation of treatment. Exploratory analyses indicated that (1) patients receiving capecitabine at some line for treatment have significantly improved OS and (2) a prognostic model can classify patients into three risk groups associated with OS. INTERPRETATION In patients with HER2-negative LR/MBC, addition of capecitabine to paclitaxel and bevacizumab significantly improved PFS, ORR and response duration. This combination was reasonably well tolerated and may be considered of use as first-line treatment in rapidly progressive disease. FUNDING F. Hoffmann-La Roche Ltd, the Netherlands.

Abstract
Since angiogenesis plays an important role in cancer growth, infiltration and metastasis, many agents targeting this pathway have been developed over the last decade. Antiangiogenic drugs interfere with this process and may inhibit neoplastic growth or induce tumor dormancy by blocking the expanding network of newly formed capillaries. Despite the initial promise, targeting angiogenesis in breast cancer has not reached major breakthroughs. Nevertheless, the immunologic role of VEGF deserves to be further explored. We aim to describe the biological mechanisms which underlie the role of angiogenesis in breast cancer carcinogenesis, to depict its contribution to the metastatic process and to review the most important clinical trials testing angiogenic inhibitors in breast cancer, including monoclonal antibodies and novel small molecules.

Abstract
BACKGROUND Combining bevacizumab with first-line or second-line chemotherapy improves progression-free survival in HER2-negative locally recurrent or metastatic breast cancer. We assessed the efficacy and safety of further bevacizumab therapy in patients with locally recurrent or metastatic breast cancer whose disease had progressed after treatment with bevacizumab plus chemotherapy. METHODS In this open-label, randomised, phase 3 trial, we recruited patients who had HER2-negative locally recurrent or metastatic breast cancer that had progressed after receiving 12 weeks or more of first-line bevacizumab plus chemotherapy from 118 centres in 12 countries. Patients were randomly assigned (1:1) by use of a central interactive voice response system using a block randomisation schedule (block size four) stratified by hormone receptor status, first-line progression-free survival, selected chemotherapy, and lactate dehydrogenase concentration, to receive second-line single-agent chemotherapy either alone or with bevacizumab (15 mg/kg every 3 weeks or 10 mg/kg every 2 weeks). Second-line therapy was continued until disease progression, unacceptable toxicity, or consent withdrawal. At progression, patients randomly assigned to chemotherapy alone received third-line chemotherapy without bevacizumab; those randomly assigned to bevacizumab continued bevacizumab with third-line chemotherapy. The primary endpoint was progression-free survival from randomisation to second-line progression or death in the intention-to-treat population. This trial is ongoing, and registered with ClinicalTrials.gov, number NCT01250379. FINDINGS Between Feb 17, 2011, and April 3, 2013, 494 patients were randomly assigned to treatment (247 in each group). The median duration of follow-up at the time of this prespecified primary progression-free survival analysis was 15·9 months (IQR 9·1-21·7) in the chemotherapy-alone group and 16·1 months (10·6-22·7) in the combination group. Progression-free survival was significantly longer for those patients treated with bevacizumab plus chemotherapy than for those with chemotherapy alone (median: 6·3 months [95% CI 5·4-7·2] vs 4·2 months [3·9-4·7], respectively, stratified hazard ratio [HR] 0·75 [95% CI 0·61-0·93], two-sided stratified log-rank p=0·0068). The most common grade 3 or more adverse events were hypertension (33 [13%] of 245 patients receiving bevacizumab plus chemotherapy vs 17 [7%] of 238 patients receiving chemotherapy alone), neutropenia (29 [12%] vs 20 [8%]), and hand-foot syndrome (27 [11%] vs 25 [11%]). Grade 3 proteinuria occurred in 17 (7%) of 245 patients receiving combination therapy and one (<1%) of 238 patients receiving chemotherapy alone. Serious adverse events were reported in 61 (25%) of 245 patients receiving bevacizumab plus chemotherapy versus 44 (18%) of 238 patients receiving chemotherapy alone. INTERPRETATION These results suggest that continued VEGF inhibition with further bevacizumab is a valid treatment option for patients with locally recurrent or metastatic HER2-negative breast cancer whose disease was stabilised or responded to first-line bevacizumab with chemotherapy.

BACKGROUND Longer duration of first-line chemotherapy for patients with metastatic breast cancer is associated with prolonged overall survival and improved progression-free survival. We investigated capecitabine added to maintenance bevacizumab after initial treatment with bevacizumab and docetaxel in this setting. METHODS We did this open-label randomised phase 3 trial at 54 hospitals in Brazil, China, Egypt, France, Hong Kong, India, Italy, Poland, Spain, and Turkey. We enrolled patients with HER2-negative measurable metastatic breast cancer; each received three to six cycles of first-line bevacizumab (15 mg/kg) and docetaxel (75-100 mg/m(2)) every 3 weeks. Progression-free patients were randomly assigned with an interactive voice-response system by block (size four) randomisation (1:1) to receive either bevacizumab and capecitabine or bevacizumab only (bevacizumab 15 mg/kg on day 1; capecitabine 1000 mg/m(2) twice per day on days 1-14, every 3 weeks) until progression, stratified by oestrogen receptor status (positive vs negative), visceral metastases (present vs absent), response status (stable disease vs response vs non-measurable), and lactate dehydrogenase concentration (≤1·5 vs >1·5 × upper limit of normal). Neither patients nor investigators were masked to allocation. The primary endpoint was progression-free survival (from randomisation) in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, NCT00929240. FINDINGS Between July 16, 2009, and March 7, 2011 (when enrolment was prematurely terminated), 284 patients received initial bevacizumab and docetaxel; 185 (65%) were randomly assigned (91 to bevacizumab and capecitabine versus 94 to bevacizumab only). Progression-free survival was significantly longer in the bevacizumab and capecitabine group than in the bevacizumab only group (median 11·9 months [95% CI 9·8-15·4] vs 4·3 months [3·9-6·8]; stratified hazard ratio 0·38 [95% CI 0·27-0·55]; two-sided log-rank p<0·0001), as was overall survival (median 39·0 months [95% CI 32·3-not reached] vs 23·7 months [18·5-31·7]; stratified HR 0·43 [95% CI 0·26-0·69]; two-sided log-rank p=0·0003). Results for time to progression were consistent with those for progression-free survival. 78 (86%) patients in the bevacizumab and capecitabine group and 72 (77%) in the bevacizumab only group had an objective response. Clinical benefit was recorded in 92 (98%) patients in the bevacizumab alone group and 90 (99%) in the bevacizumab and capecitabine group. Mean change from baseline in global health score did not differ significantly between groups. Grade 3 or worse adverse events during the maintenance phase were more common with bevacizumab and capecitabine than with bevacizumab only (45 [49%] of 91 patients vs 25 [27%] of 92 patients). The most common grade 3 or worse events were hand-foot syndrome (28 [31%] in the bevacizumab and capecitabine group vs none in the bevacizumab alone group), hypertension (eight [9%] vs three [3%]), and proteinuria (three [3%] vs four [4%]). Serious adverse events were reported by ten (11%) patients in the bevacizumab and capecitabine group and seven (8%) patients in the bevacizumab only group. INTERPRETATION Despite prematurely terminated accrual and the lack of information about post-progression treatment, both progression-free survival and overall survival were significantly improved with bevacizumab and capecitabine compared with bevacizumab alone as maintenance treatment. These results might inform future maintenance trials and current first-line treatment strategies for HER2-negative metastatic breast cancer. FUNDING F Hoffmann-La Roche.

Abstract
Purpose Optical imaging techniques for measuring tissue hemoglobin concentration have been recently accepted as a way to assess tumor vascularity and oxygenation. We investigated the correlation between early optical response to single-agent bevacizumab and treatment outcome. Methods Seven patients with advanced or metastatic breast cancer were treated with single-agent bevacizumab followed by addition of weekly paclitaxel. Optical imaging of patient's breasts was performed to measure tumor total hemoglobin concentration (tHb) and oxygen saturation (stO2) at baseline and on days 1, 3, 6, 8, and 13 after the first infusion of bevacizumab. To assess early metabolic response, 2-deoxy-2-(18F)-fluoro-D-glucose (FDG) positron emission tomography/computed tomography (PET/CT), 18F-fluoromisonidazole (FMISO)-PET/CT, and magnetic resonance imaging were performed at baseline and after two cycles of the regimen. Results Seven patients were grouped as responders (n = 4) and nonresponders (n = 3) on the basis of metabolic response measured by FDG-PET/CT. The responders showed remarkable tumor shrinkage and low accumulations of FMISO tracer relative to those of the nonresponders at the completion of two cycles of chemotherapy. Tumors of both groups showed remarkable attenuation of mean tHb as early as day 1 after therapy initiation. The nonresponders had lower baseline stO2 levels compared with adjacent breast tissue stO2 levels along with a pattern of steadily low stO2 levels during the observation window. On the other hand, the responders appeared to sustain high stO2 levels with temporal fluctuation. Conclusions Low tumor stO2 level after single-agent bevacizumab treatment was characteristic of the nonresponders. Tumor stO2 level could be a predictor of an additional benefit of bevacizumab over that provided by paclitaxel.

Abstract
UNLABELLED Angiogenesis is a key component of cancer growth, invasion and metastasis. Therefore, inhibition of angiogenesis is an attractive strategy for the treatment of cancer. We systematically describe phase II and III clinical trials of bevacizumab for the treatment of breast cancer. METHODS A computer-based literature search was carried out using PUBMED and conference databases. Original phase II and III studies reporting ≥15 patients who received bevacizumab were included. RESULTS 41 phase II trials were identified in the metastatic setting. Most trials found bevacizumab treatment feasible. Response rates (RR) varied from 0% to 76.5%, time to progression (TTP)/progression free survival (PFS) from 2.4 to 25.3 months and overall survival from 11.5 to more than 38 months. 14 phase III trials including more than 4400 patients with MBC unanimously showed increased RR and PFS, however, no trials demonstrated an OS benefit. In the neoadjuvant setting 23 phase II and III trials were identified. All studies found increased pCR/tpCR but no benefit in terms of OS could be demonstrated. The only study conducted in the adjuvant setting failed to show any survival benefit of bevacizumab. CONCLUSION Despite increased response rates in both the metastatic and neoadjuvant setting, bevacizumab has failed to show any OS benefit. Future trials should include identification of robust predictive biomarkers in order to improve our understanding of molecular biomarkers and mechanisms.

Abstract
An alternative or follow-up adjunct to conventional maximum tolerated dose (MTD) chemotherapy now in advanced phase III clinical trial assessment is metronomic chemotherapy--the close regular administration of low doses of drug with no prolonged breaks. A number of preclinical studies have shown metronomic chemotherapy can cause long term survival of mice with advanced cancer, including metastatic disease, in the absence of overt toxicity, especially when combined with targeted antiangiogenic drugs. However, similar to MTD chemotherapy acquired resistance eventually develops, the basis of which is unknown. Using a preclinical model of advanced human ovarian (SKOV-3-13) cancer in SCID mice, we show that acquired resistance can develop after terminating prolonged (over 3 months) successful therapy utilizing daily oral metronomic topotecan plus pazopanib, an oral antiangiogenic tyrosine kinase inhibitor (TKI). Two resistant sublines were isolated from a single mouse, one from a solid tumor (called KH092-7SD, referred to as 7SD) and another from ascites tumor cells (called KH092-7AS, referred to as 7AS). Using these sublines we show acquired resistance to the combination treatment is due to tumor cell alterations that confer relative refractoriness to topotecan. The resistant phenotype is heritable, associated with reduced cellular uptake of topotecan and could not be reversed by switching to MTD topotecan or to another topoisomerase-1 inhibitor, CPT-11, given either in a metronomic or MTD manner nor switching to another antiangiogenic drug, e.g. the anti-VEGFR-2 antibody, DC101, or another TKI, sunitinib. Thus, in this case cross resistance seems to exist between MTD and metronomic topotecan, the basis of which is unknown. However, gene expression profiling revealed several potential genes that are stably upregulated in the resistant lines, that previously have been implicated in resistance to various chemotherapy drugs, and which, therefore, may contribute to the drug resistant phenotype.

Abstract
The development of new blood vessels is a crucial step in breast cancer growth, progression and dissemination, making it a promising therapeutic target. Breast cancer has a heterogeneous nature and the diversity of responsible angiogenic pathways between different tumors has been studied for many years. Inhibiting different targets in these pathways has been under investigation in preclinical and clinical studies for more than decades, among which antibody against vascular endothelial growth factor is the most studied. However, the clinical impact from antiangiogenic treatment alone or in combination with standard chemotherapeutic regimens has been relatively small till today. In this review, we summarize the most clinically relevant data from breast cancer treatment clinical trials and discuss safety and efficacy of common antiangiogenic therapies as well as biological predictive markers.

Abstract
Viewed as a whole, the aggregate outcomes of a number of positive randomized phase III clinical trial results evaluating the VEGF-pathway targeting antiangiogenic drug bevacizumab, with or without concurrent chemotherapy, in metastatic breast cancer patients have been disappointingly modest. In the case of antiangiogenic tyrosine kinase inhibitors (TKIs) the results have been negative. Nevertheless, several findings indicate antiangiogenic drugs, especially bevacizumab, are active and can lead to demonstrable clinical benefit in some patients, thus stimulating research into developing strategies to significantly improve their efficacy and reduce toxicity. Some of these initiatives include: 1) discovery and validation of predictive markers that can prospectively identify patients more likely to benefit from antiangiogenic therapy; 2) recognition that the nature of the chemotherapy partner or backbone can strongly impact outcomes when combined with antiangiogenic drugs such as bevacizumab, and thus developing what may be improved combination chemotherapy partner regimens, e.g. metronomic chemotherapy; 3) evaluating prospectively in more depth whether subtypes of the disease-especially triple negative or inflammatory breast cancer-are more responsive to antiangiogenic therapy than other subtypes; 4) evaluating new agents that inhibit angiogenesis in a VEGF-independent manner and other types of drug that can be effectively combined with antiangiogenics, e.g. c-met inhibitors; 5) uncovering the basis of resistance or relapse/progression on the therapy with antiangiogenic drugs; 6) development of improved predictive preclinical breast cancer models for therapy testing, e.g. treatment of mice with established multi-organ breast cancer metastatic disease or genetically engineered mouse models of breast cancer, or mice bearing patient derived breast cancer tissue xenografts.

Abstract
Bevacizumab (Avastin™) is a humanized monoclonal antibody directed against vascular endothelial growth factor. In patients with human epidermal growth factor receptor type 2 (HER2)-negative metastatic breast cancer, bevacizumab is indicated as first-line therapy in combination with paclitaxel, or in combination with capecitabine when treatment with other chemotherapy options, including taxanes or anthracyclines, is not considered appropriate. This article reviews the efficacy and tolerability of these combination therapies in the first-line treatment of patients with metastatic breast cancer, and summarizes the pharmacological properties of bevacizumab. In randomized, controlled, phase III trials in patients with predominantly HER2-negative metastatic or locally recurrent breast cancer, the addition of bevacizumab to paclitaxel or capecitabine significantly prolonged progression-free survival (PFS; investigator assessment) by a median of 5.9 and 2.9 months, respectively, relative to paclitaxel or capecitabine alone. It also significantly increased the objective response rate, but not overall survival. Independent reviews of data supported the results of the primary analyses of investigator-assessed PFS. However, as the efficacy of bevacizumab in combination with capecitabine appears to be less than that of other available options, it should be used only if treatment with other chemotherapy options are not considered appropriate. The addition of bevacizumab to paclitaxel had no significant adverse effects on health-related quality of life. Efficacy data from two routine clinical practice studies were generally consistent with those from the phase III trials. Bevacizumab had generally acceptable tolerability when administered in combination with paclitaxel or capecitabine as first-line therapy in these studies, and adverse events were consistent with the known tolerability profiles of the individual agents. The most common adverse events associated with bevacizumab combination therapy in phase III trials were sensory neuropathy and grade ≥3 hypertension, occurring more frequently with combination therapy than with chemotherapy alone. Potentially life-threatening events, such as venous thromboembolism, gastrointestinal perforation, arterial thromboembolism, haemorrhage and left ventricular dysfunction, occurred in ≤5% of patients receiving combination therapy in these trials. In conclusion, bevacizumab administered in combination with paclitaxel, or in combination with capecitabine if other chemotherapy regimens are not appropriate, may be considered as an option for the first-line treatment of patients with HER2-negative metastatic breast cancer.
