Engineered bispecific antibodies targeting the interleukin-6 and -8 receptors potently inhibit cancer cell migration and tumor metastasis. Mol Ther 2022; 30:3430-3449. [PMID: 35841152 PMCID: PMC9637575 DOI: 10.1016/j.ymthe.2022.07.008] [Citation(s) in RCA: 15] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2022] [Revised: 06/12/2022] [Accepted: 07/09/2022] [Indexed: 12/15/2022] Open
Abstract
Simultaneous inhibition of interleukin-6 (IL-6) and interleukin-8 (IL-8) signaling diminishes cancer cell migration, and combination therapy has recently been shown to synergistically reduce metastatic burden in a preclinical model of triple-negative breast cancer. Here, we have engineered two novel bispecific antibodies that target the IL-6 and IL-8 receptors to concurrently block the signaling activity of both ligands. We demonstrate that a first-in-class bispecific antibody design has promising therapeutic potential, with enhanced selectivity and potency compared with monoclonal antibody and small-molecule drug combinations in both cellular and animal models of metastatic triple-negative breast cancer. Mechanistic characterization revealed that our engineered bispecific antibodies have no impact on cell viability, but profoundly reduce the migratory potential of cancer cells; hence they constitute a true anti-metastatic treatment. Moreover, we demonstrate that our antibodies can be readily combined with standard-of-care anti-proliferative drugs to develop effective anti-cancer regimens. Collectively, our work establishes an innovative metastasis-focused direction for cancer drug development.

Shared decision making for patients with breast and gynecologic malignancies undergoing chemotherapy associated with persistent alopecia. Gynecol Oncol Rep 2022; 44:101095. [PMID: 36388759 PMCID: PMC9640350 DOI: 10.1016/j.gore.2022.101095] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2022] [Revised: 10/26/2022] [Accepted: 10/28/2022] [Indexed: 11/06/2022] Open
Abstract
Objective To assess patient-perceived involvement in shared decision making among those diagnosed with breast or gynecologic malignancies undergoing chemotherapy associated with persistent chemotherapy-induced alopecia (pCIA). We also sought to identify factors that influence shared decision making. Methods We recruited patients from the Gynecologic Medical Oncology and Breast Medicine Services at a large academic center for this prospective cohort study. All patients were scheduled to start chemotherapy between June 1, 2017 and December 31, 2017. Following medical consultation, including discussion of the risk of pCIA, patients completed the 9-item Shared Decision Making Questionnaire (SDM-Q-9). Clinical and sociodemographic information was also collected. Univariate analysis was used to evaluate SDM-Q-9 total scores and their constituents for all variables. Results Sixty-one patients completed the survey. The median total SDM-Q-9 score was 95.6 (95% CI: 90-100). Most patients (n = 57, 93%) reported a high level of involvement (SDM-Q-9 total score > 66). There was no difference in total scores between patients with breast compared with gynecologic cancer (P > .05). By individual item, the scores for item Q1 ("My doctor made clear that a decision needs to be made") were significantly lower for Black patients and those with advanced disease (P < .05). Conclusions Most patients indicated they were adequately involved in shared decision making regarding chemotherapy treatment options and their risk for pCIA. Patients from underrepresented populations and those with advanced disease may benefit from additional support from their clinicians to better address the anticipated psychosocial impacts of pCIA and facilitate the provision of optimal and equitable care.

Abstract
In breast cancer therapy, Gemcitabine (Gem) is an antineoplastic antimetabolite with greater anticancer efficacy and tolerability. However, effectiveness of Gem is limited by its off-target effects. The synergistic potential of MUC1 (mucin 1) inhibitors and Gem-loaded polymeric nanoparticles (NPs) was discussed in this work in order to reduce dose-related toxicities and enhance the therapeutic efficacy. The double emulsion solvent evaporation method was used to prepare poly(ethylene glycol) methyl ether-block-poly-caprolactone (PEG-PCL)-loaded Gem and MUC 1 inhibitor NPs. The average size of Gem and MUC 1 inhibitor-loaded NPs was 128 nm, with a spherical shape. Twin-loaded NPs containing Gem and the MUC1 inhibitor decreased IC50 and behaved synergistically. Furthermore, in vitro mechanistic studies, that is, loss of MMP, clonogenic assay, Annexin V FITC assay, and Western blotting to confirm apoptosis with simultaneous induction of autophagy using acridine orange (AO) staining were performed in this study. Furthermore, the investigated NPs upon combination exhibited greater loss of MMP and decreased clonogenic potential with simultaneous induction of autophagy in MCF-7 cells. Annexin V FITC clearly showed the percentage of apoptosis while Western blotting protein expression analysis revealed an increase in caspase-3 activity with simultaneous decrease in Bcl-2 protein expression, a hallmark of apoptosis. The effectiveness of the Ehrlich ascites solid (EAT) mice treated with Gem-MUC1 inhibitor NPs was higher than that of the animals treated alone. Overall, the combined administration of Gem and MUC1 inhibitor-loaded NPs was found to be more efficacious than Gem and MUC1 inhibitor delivered separately.

Abstract
Fatigue is a highly prevalent symptom in both cancer patients and the older population, and it contributes to quality-of-life impairment. Cancer treatment-related fatigue should thus be included in the risk/benefit assessment when introducing any treatment, but tools are lacking to a priori estimate such risk. This scoping review was designed to report the current evidence regarding the frequency of fatigue for the different treatment regimens proposed for the main cancer indications, with a specific focus on age-specific data, for the following tumors: breast, ovary, prostate, urothelium, colon, lung and lymphoma. Fatigue was most frequently reported using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) versions 3 to 5. A total of 324 regimens were analyzed; data on fatigue were available for 217 (67%) of them, and data specific to older patients were available for 35 (11%) of them; recent pivotal trials have generally reported more fatigue grades than older studies, illustrating increasing concern over time. This scoping review presents an easy-to-understand summary that is expected to provide helpful information for shared decisions with patients regarding the anticipation and prevention of fatigue during each cancer treatment.

Abstract
Background Although several novel resistant breast cancer cell lines have been established, only a few resistant breast cancer cell lines overexpress breast cancer resistance proteins (BCRP). The aim of this study was to establish new resistant breast cancer cell lines overexpressing BCRP using SN38 (7-ethyl-10-hydroxycamptothecin), an active metabolite of irinotecan and was to discover genes and mechanisms associated with multidrug resistance. Methods SN38-resistant T47D breast cancer cell sublines were selected from the wild-type T47D cells by gradually increasing SN38 concentration. The sensitivity of the cells to anti-cancer drugs was assessed by 3-(4,5-methylthiazol-2-yl)-2,5-diphenyl-tetrazolium bromide (MTT) assay. Expression profiles of the resistance-related transporters were examined using RT-qPCR, and western blot analysis. Intracellular fluorescent dye accumulation in the resistant cells was determined using flow cytometry. Results The SN38-resistant T47D breast cancer cell sublines T47D/SN120 and T47D/SN150 were established after long-term exposure (more than 16 months) of wild-type T47D cells to 120 nM and 150 nM SN38, respectively. T47D/SN120 and T47D/SN150 cells were more resistant to SN38 (14.5 and 59.1 times, respectively), irinotecan (1.5 and 3.7 times, respectively), and topotecan (4.9 and 12 times, respectively), than the wild-type parental cells. Both T47D/SN120 and T47D/SN150 sublines were cross-resistant to various anti-cancer drugs. These resistant sublines overexpressed mRNAs of MRP1, MRP2, MRP3, MRP4, and BCRP. The DNA methylase inhibitor 5-aza-2′-deoxycytidine and the histone deacetylase inhibitor trichostatin A increased the expression levels of BCRP, MRP1, MRP2, MRP3, and MRP4 transcripts in T47D/WT cells. Fluorescent dye accumulation was found to be lower in T47D/SN120 and T47D/SN150 cells, compared to that in T47D/WT cells. However, treatment with known chemosensitizers increased the intracellular fluorescent dye accumulation and sensitivity of anti-tumor agents. Conclusion T47D/SN120 and T47D/SN150 cells overexpressed MRP1, MRP2, MRP3, MRP4, and BCRP, which might be due to the suppression of epigenetic gene silencing via DNA hypermethylation and histone deacetylation. Although these resistant cells present a higher resistance to various anti-cancer drugs than their parental wild-type cells, multidrug resistance was overcome by treatment with chemosensitizers. These SN38 resistant T47D breast cancer cell sublines expressing resistance proteins can be useful for the development of new chemosensitizers.

Abstract
Background When chemotherapy is indicated in patients with early breast cancer, regimens that contain anthracyclines and taxanes are established standard treatments. Gemcitabine has shown promising effects on the response and prognosis in patients with metastatic breast cancer. The SUCCESS-A trial (NCT02181101) examined the addition of gemcitabine to a standard chemotherapy regimen in high-risk early breast cancer patients. Methods A total of 3754 patients with at least one of the following characteristics were randomly assigned to one of the two treatment arms: nodal positivity, tumor grade 3, age ≤ 35 years, tumor larger than 2 cm, or negative hormone receptor status. The treatment arms received either three cycles of 5-fluorouracil, epirubicin, and cyclophosphamide, followed by three cycles of docetaxel (FEC → Doc); or three cycles of FEC followed by three cycles of docetaxel and gemcitabine (FEC → Doc/Gem). The primary study aim was disease-free survival (DFS), and the main secondary objectives were overall survival (OS) and safety. Results No differences were observed in the 5-year DFS or OS between FEC → Doc and FEC → Doc/Gem. The hazard ratio was 0.93 (95% CI, 0.78 to 1.12; P = 0.47) for DFS and 0.94 (95% CI, 0.74 to 1.19; P = 0.60) for OS. For patients treated with FEC → Doc and FEC → Doc/Gem, the 5-year probabilities of DFS were 86.6% and 87.2%, and the 5-year probabilities of OS were 92.8% and 92.5%, respectively. Conclusion Adding gemcitabine to a standard chemotherapy does not improve the outcomes in patients with high-risk early breast cancer and should therefore not be included in the adjuvant treatment setting.

Permanent Chemotherapy-Induced Alopecia in Patients with Breast Cancer: A 3-Year Prospective Cohort Study. Oncologist 2018; 24:414-420. [PMID: 30120165 PMCID: PMC6519756 DOI: 10.1634/theoncologist.2018-0184] [Citation(s) in RCA: 51] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2018] [Accepted: 06/14/2018] [Indexed: 01/28/2023] Open
Abstract
Chemotherapy‐induced alopecia is (CIA) considered temporary; however, some patients report persistent alopecia several years after chemotherapy. Long‐term prospective data on the incidence and impact of permanent CIA is scarce. This article reports the results of a study conducted to estimate the long‐term incidence of persistent CIA in a cohort of breast cancer patients with measurements of hair volume and density before and after chemotherapy. Background. Although chemotherapy‐induced alopecia (CIA) is considered temporary, some patients report persistent alopecia several years after chemotherapy. There is, however, a paucity of long‐term prospective data on the incidence and impact of permanent CIA (PCIA). The objective of our study was to estimate the long‐term incidence of PCIA in a cohort of patients with breast cancer whose hair volume and density were measured prior to chemotherapy and who were followed for 3 years after chemotherapy. Materials and Methods. Prospective cohort study of consecutive patients ≥18 years of age with postoperative diagnosis of stage I–III breast cancer expected to receive adjuvant chemotherapy at the outpatient breast cancer clinic at the Samsung Medical Center in Seoul, Korea, from February 2012 to July 2013 (n = 61). Objective hair density and thickness were measured using a noninvasive bioengineering device. Results. The proportion of participants who had PCIA at 6 months and 3 years was 39.5% and 42.3%, respectively. PCIA was characterized in most patients by incomplete hair regrowth. Patients who received a taxane‐based regimen were more likely to experience PCIA compared with patients with other types of chemotherapy. At a 3‐year follow‐up, hair thinning was the most common problem reported by study participants (75.0%), followed by reduced hair volume (53.9%), hair loss (34.6%), and gray hair (34.6%). Conclusion. PCIA is a common adverse event of breast cancer adjuvant cytotoxic chemotherapy. Clinicians should be aware of this distressing adverse event and develop supportive care strategies to counsel patients and minimize its impact on quality of life. Implications for Practice. Knowledge of permanent chemotherapy‐induced alopecia, an under‐reported adverse event, should lead to optimized pretherapy counseling, anticipatory coping techniques, and potential therapeutic strategies for this sequela of treatment.

Abstract
This meta-analysis was designed to compare the efficacy and safety of gemcitabine-based regimens for the treatment advanced breast cancer (ABC). Altogether 15 studies involving 8195 ABC patients were retrieved for analysis. Compared with non-gemcitabine-based chemotherapies, patients receiving gemcitabine-based therapy exhibited better overall survival (OS), progression free survival (PFS), and objective response rate (ORR) (HR = 1.12, 95% CI 1.05 to 1.19; HR = 1.16, 95% CI 1.03 to 1.30; HR = 1.14, 95% CI 1.04 to 1.24). Grade 3/4 hematologic toxicity was significantly high but manageable in gemcitabine-based groups. Subgroup analysis revealed that patients with first-line gemcitabine-based chemotherapy had better OS (HR = 1.19, 95% CI 1.07 to 1.32), PFS (HR = 1.17, 95% CI 1.08 to 1.27), and ORR (RR = 1.16, 95% CI 1.02 to 1.32). In addition, additional gemcitabine chemotherapy also showed better OS (HR = 1.17, 95% CI 1.06 to 1.30), PFS (HR = 1.20, 95% CI 1.11 to 1.30) and ORR (RR = 1.23, 95% CI 1.06 to 1.42) than gemcitabine replacement therapy. Furthermore, patients receiving gemcitabine-taxanes-based regimens had better OS (HR = 1.17, 95% CI 1.06 to 1.28), PFS (HR = 1.12, 95% CI 1.04 to 1.20) and ORR (RR = 1.17, 95% CI 1.01 to 1.35) than patients with non-gemcitabine-taxanes-based chemotherapy. These findings indicate that gemcitabine combination regimens could serve as a promising regimen for ABC patients, though increased hematologic toxicity should be considered with caution.

Abstract
Agents that target microtubule (MT) dynamics have been used extensively for the treatment of metastatic breast cancer (MBC). Among these agents are taxanes (solvent-based paclitaxel [sb-paclitaxel], docetaxel, and nab-paclitaxel) and non-taxanes, such as eribulin and ixabepilone. Although these agents have been approved for the treatment of MBC, questions regarding the ideal agent, regimen (single agent vs. combination vs. sequential), and schedule still remain. This systematic review examined pivotal trials for taxanes, eribulin, and ixabepilone as well as first-line taxane trials in MBC. Only randomized trials that enrolled ≥ 100 patients were included. Publications on combination regimens with targeted agents were excluded unless they also included a comparison between nontargeted regimens. The studies were grouped into taxane versus taxane, sb-paclitaxel versus non-taxane, and docetaxel versus non-taxane regimens. In taxane versus taxane comparisons, the efficacy of sb-paclitaxel and docetaxel appeared similar, nab-paclitaxel every 3 weeks (q3w) appeared superior to sb-paclitaxel q3w, and weekly nab-paclitaxel appeared superior to docetaxel. In general, taxane regimens demonstrated higher overall response rates (ORRs) versus non-taxane regimens; however, only 2 trials demonstrated longer overall survival (OS) for taxane regimens. Taxanes will likely continue to be used in earlier lines of therapy, whereas eribulin and ixabepilone may be more appropriate for later lines of treatment. Ongoing research may identify biomarkers that could help in selecting the appropriate MT-targeted agent for a given patient.

Abstract
BACKGROUND It is generally accepted that taxanes are among the most active chemotherapy agents in the management of metastatic breast cancer. This is an update of a Cochrane review first published in 2003. OBJECTIVES The objective of this review was to compare taxane-containing chemotherapy regimens with regimens not containing a taxane in the management of women with metastatic breast cancer. SEARCH METHODS In this review update, we searched the Cochrane Breast Cancer Group Specialised Register, MEDLINE, EMBASE, the World Health Organization's International Clinical Trials Registry Platform (WHO ICTRP), and ClinicalTrials.gov on 14 February 2013 using keywords such as 'advanced breast cancer' and 'chemotherapy'. We searched reference lists of articles, contacted study authors, and did not apply any language restrictions. SELECTION CRITERIA Randomised controlled trials comparing taxane-containing chemotherapy regimens to regimens without taxanes in women with metastatic breast cancer. We included published and unpublished studies. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and extracted data. We derived hazard ratios (HRs) for overall survival, time to progression, and time to treatment failure where possible, and used a fixed-effect model for meta-analysis. We represented objective tumour response rates and toxicity as risk ratios (RRs). We extracted quality of life data where present. MAIN RESULTS This review included 28 studies. The updated analysis included 6871 randomised women, while the original review had 3643 women. Of the 28 included studies, we considered 19 studies to be at low risk of bias overall; however, some studies failed to report details on allocation concealment and methods of outcome assessment for those outcomes that are more likely to be influenced by a lack of blinding (for example tumour response rate). Studies varied in the taxane-containing chemotherapy backbone, and the comparator arms and were categorised into three groups: Regimen A plus taxane versus Regimen A (2 studies); Regimen A plus taxane versus Regimen B (14 studies); and single-agent taxane versus Regimen C (13 studies). Thirteen studies used paclitaxel, 14 studies used docetaxel, and 1 study allowed the investigator to decide on the type of taxane; the majority of studies delivered a taxane every 3 weeks. Twenty studies administered taxanes as first-line treatment, and 21 studies involved anthracycline naïve women in the metastatic setting. The combined HR for overall survival and time to progression favoured the taxane-containing regimens (HR 0.93, 95% confidence interval (CI) 0.88 to 0.99, P = 0.002, deaths = 4477; and HR 0.92, 95% CI 0.87 to 0.97, P = 0.002, estimated 5122 events, respectively) with moderate to substantial heterogeneity across trials. If the analyses were restricted to studies of first-line chemotherapy, this effect persisted for overall survival (HR 0.93, 95% CI 0.87 to 0.99, P = 0.03) but not for time to progression (HR 0.96, 95% CI 0.90 to 1.02, P = 0.22). Tumour response rates appeared to be better with taxane-containing chemotherapy in assessable women (RR 1.20, 95% CI 1.14 to 1.27, P < 0.00001) with substantial heterogeneity across studies. Taxanes were associated with an increased risk of neurotoxicity (RR 4.84, 95% CI 3.18 to 7.35, P < 0.00001, 24 studies) and hair loss (RR 2.37, 95% CI 1.45 to 3.87, P = 0.0006, 11 studies) but less nausea/vomiting compared to non-taxane-containing regimens (RR 0.62, 95% CI 0.46 to 0.83, P = 0.001, 26 studies). Leukopaenia and treatment-related death did not differ between the two groups (RR 1.07, 95% CI 0.97 to 1.17, P = 0.16, 28 studies; and RR 1.00, 95% CI 0.63 to 1.57, P = 0.99, 23 studies, respectively). For quality of life measures, none of the individual studies reported a difference in overall or any of quality of life subscales between taxane-containing and non-taxane chemotherapy regimens. AUTHORS' CONCLUSIONS Taxane-containing regimens appear to improve overall survival, time to progression, and tumour response rate in women with metastatic breast cancer. Taxanes are also associated with an increased risk of neurotoxicity but less nausea and vomiting compared to non-taxane-containing regimens. The considerable heterogeneity encountered across studies probably reflects the varying efficacy of the comparator regimens used in these studies and indicates that taxane-containing regimens are more effective than some, but not all, non-taxane-containing regimens.

A network meta-analysis of everolimus plus exemestane versus chemotherapy in the first- and second-line treatment of estrogen receptor-positive metastatic breast cancer. Breast Cancer Res Treat 2015; 152:95-117.

Abstract
The goal of this study was to compare the efficacy and toxicity of chemotherapy to exemestane plus everolimus (EXE/EVE) through a network meta-analysis (NMA) of randomized controlled trials. NMA methods extend standard pairwise meta-analysis to allow simultaneous comparison of multiple treatments while maintaining randomization of individual studies. The method enables "direct" evidence (i.e., evidence from studies directly comparing two interventions) and "indirect" evidence (i.e., evidence from studies that do not compare the two interventions directly) to be pooled under the assumption of evidence consistency. We used NMA to evaluate progression-free survival (PFS) and time to progression (TTP) curves in 34 studies, and response rate (RR) and the hazard ratios (HRs) of the PFS/TTP in 36 studies. A number needed to treat (NNT) analysis was also performed as well as descriptive comparison of reported toxicities. The NMA for PFS/TTP curves and for HR shows EXE/EVE is more efficacious than capecitabine plus sunitinib, CMF, megestrol acetate and tamoxifen, with an average of related-PFS/TTP difference ranging from about 10 months for capecitabine plus sunitinib to more than 6 months for tamoxifen. The NMA for overall RR shows that EXE/EVE provides a better RR than bevacizumab plus capecitabine, capecitabine, capecitabine plus sorafenib, capecitabine plus sunitinib, CMF, gemcitabine plus epirubicin plus paclitaxel, EVE plus tamoxifen, EXE, FEC, megestrol acetate, mitoxantrone, and tamoxifen. Finally, the NMA for NNT shows that EXE/EVE is more beneficial as compared to BMF, capecitabine, capecitabine plus sunitinib, CMF, FEC, megestrol acetate, mitoxantrone, and tamoxifen. The combination of EXE/EVE as first- or second-line therapy for ER+ve/HER2-ve metastatic breast cancer is more efficacious than several chemotherapy regimens that were reported in the literature. Toxicities also favored EXE/EVE in most instances.

Abstract
Data on chemotherapy-induced alopecia (CIA) as a side effect of cancer treatment are scarce. CIA is given minimal attention in clinical trials and in the literature. However, when asking the patients with cancer for their opinion, CIA appears to have a major impact, particularly on body image and quality of life. Currently, there is no commonly used measure to evaluate CIA; It is time to improve the management and measurement of CIA.

Abstract
Purpose Gemcitabine/taxanes-based combination shows anti-tumor activity for the treatment of metastatic breast cancer, but there is a debate regarding the advantages of gemcitabine and taxanes regimens as a first-line or second-line treatment for metastatic breast cancer. Here we conducted a systematic review and meta-analysis to compare the efficacy and toxicity for patients receiving chemotherapy with or without GT-based regimens. Methods The randomized controlled trials were performed by searching Pubmed, MEDLINE, EMBASE, and conference proceedings. We identified eight randomized controlled trials and then extracted and combined the data using to calculate hazard ratios (HR). The primary outcomes were progression-free survival (PFS) and time to progression (TTP). The secondary outcomes were overall survival (OS) and acute toxicity. A meta-analysis was performed using Review Manager Version 4.2. Results Eight eligible trails were identified. These studies involved 2234 patients with metastatic breast cancer, (1122 patients received GT-based combination regimen and 1112 patients received a regimen without the combination). A fixed-effects model meta-analysis showed that ORR and TTP are superior for GT-treated patients ORR (OR = 1.28, 95% CI 1.07-1.53), TTP (HR = 0.80; 95% CI 0.71-0.89). And GT-based combination significantly improved OS in the first-line subgroup (HR = 0.84; 95% CI 0.71-0.99). However, there were significant differences regarding acute hematological toxicity, particularly thrombocytopenia. Conclusion Gemcitabine/taxanes-treated patients with metastatic breast cancer showed a significant improvement in the ORR, TTP and OS (first-line background) compared to patients not treated with the combination regimen.

Abstract
Background: Many phase II trials investigated the combination of Gemcitabine (G) and Vinorelbine (V) in the treatment of metastatic breast cancer (MBC) with variable outcomes. This study was conducted to explore whether this combination was effective and tolerable in MBC patients who were heavily pretreated with anthracyclines and taxanes. Methods: A phase I study was conducted first to establish the maximum tolerated dose (MTD) of the G and V combination in MBC patients. Then, a phase II study evaluated the response rates, the median time to progression (TTP), the overall survival (OS) as well as the toxicities resulting from this combination at the MTD. Results: Nine patients were enrolled in the phase I study. The MTD was identified as 700mg/m2 of G on days 1 and 8 in combination with 15 mg/m2 of V on days 2 and 9, every 21 days. Twenty-one of 25 patients involved in the phase II study were evaluable for response. No complete or partial responses were achieved; 6 patients (24.0%) had stable disease and 15 (60.0%) progressed. The median TTP was 2 months and the median OS 10 months. Grade 3/4 Neutropenia was the major hematologic toxicity, occurring in 52% of the cycles. The most common non-hematologic grade 3/4 toxicities were fatigue (18%), myalgias (17%) and arthralgias (13%). Conclusion: In heavily pretreated patients with MBC, the combination of G and V at the doses stated above was ineffective as it did not induce partial or complete responses. Other chemotherapy agents or combinations should be evaluated in future studies.

Abstract
BACKGROUND Anthracyclines and taxanes have been the standard neoadjuvant chemotherapies for breast cancer in the past decade. We aimed to assess safety and efficacy of the addition of gemcitabine to accelerated paclitaxel with epirubicin and cyclophosphamide, and also the effect of sequencing the blocks of epirubicin and cyclophosphamide and paclitaxel (with or without gemcitabine). METHODS In our randomised, open-label, 2×2 factorial phase 3 trial (Neo-tAnGo), we enrolled women (aged >18 years) with newly diagnosed breast cancer (tumour size >20 mm) at 57 centres in the UK. Patients were randomly assigned via a central randomisation procedure to epirubicin and cyclophosphamide then paclitaxel (with or without gemcitabine) or paclitaxel (with or without gemcitabine) then epirubicin and cyclophosphamide. Four cycles of each component were given. The primary endpoint was pathological complete response (pCR), defined as absence of invasive cancer in the breast and axillary lymph nodes. This study is registered with EudraCT (2004-002356-34), ISRCTN (78234870), and ClinicalTrials.gov (NCT00070278). FINDINGS Between Jan 18, 2005, and Sept 28, 2007, we randomly allocated 831 participants; 207 received epirubicin and cyclophosphamide then paclitaxel; 208 were given paclitaxel then epirubicin and cyclophosphamide; 208 had epirubicin and cyclophosphamide followed by paclitaxel and gemcitabine; and 208 received paclitaxel and gemcitabine then epirubicin and cyclophosphamide. 828 patients were eligible for analysis. Median follow-up was 47 months (IQR 37-51). 207 (25%) patients had inflammatory or locally advanced disease, 169 (20%) patients had tumours larger than 50 mm, 413 (50%) patients had clinical involvement of axillary nodes, 276 (33%) patients had oestrogen receptor (ER)-negative disease, and 191 (27%) patients had HER2-positive disease. Addition of gemcitabine did not increase pCR: 70 (17%, 95% CI 14-21) of 404 patients in the epirubicin and cyclophosphamide then paclitaxel group achieved pCR compared with 71 (17%, 14-21) of 408 patients who received additional gemcitabine (p=0·98). Receipt of a taxane before anthracycline was associated with improved pCR: 82 (20%, 95% CI 16-24) of 406 patients who received paclitaxel with or without gemcitabine followed by epirubicin and cyclophosphamide achieved pCR compared with 59 (15%, 11-18) of 406 patients who received epirubicin and cyclophosphamide first (p=0·03). Grade 3 toxicities were reported at expected levels: 173 (21%) of 812 patients who received treatment and had full treatment details had grade 3 neutropenia, 66 (8%) had infection, 41 (5%) had fatigue, 41 (5%) had muscle and joint pains, 37 (5%) had nausea, 36 (4%) had vomiting, 34 (4%) had neuropathy, 23 (3%) had transaminitis, 16 (2%) had acute hypersensitivity, and 20 (2%) had a rash. 86 (11%) patients had grade 4 neutropenia and 3 (<1%) had grade 4 infection. INTERPRETATION Although addition of gemcitabine to paclitaxel and epirubicin and cyclophosphamide chemotherapy does not improve pCR, sequencing chemotherapy so that taxanes are received before anthracyclines could improve pCR in standard neoadjuvant chemotherapy for breast cancer.

Abstract
OBJECTIVES To compare the effects of gemcitabine-based chemotherapy and gemcitabine-free regimens, a meta-analysis of all relevant randomized controlled trials was performed to investigate the improvement in overall response rate (ORR), time to progression (TTP), and overall survival (OS). A subgroup of gemcitabine-based doublet compared with single agent was also analyzed. METHODS The PubMed and Embase databases were searched for relevant publications reporting randomized controlled trials comparing gemcitabine-based chemotherapy and gemcitabine-free regimens between January 1990 and December 2012. Hazard ratios (HRs) with their 95% confidence intervals (CIs), or data for calculating HRs with 95% CI were derived. RESULTS Nine trials with a total of 2651 patients were included in this meta-analysis. Compared with gemcitabine-free chemotherapy, gemcitabine-based therapy demonstrated no improvement in terms of ORR (HR 1.09, 95% CI 0.73-1.62; P = 0.67), TTP (HR 0.91, 95% CI 0.72-1.15; P = 0.44) and OS (HR 1.05, 95% CI 0.88-1.25; P = 0.60). In a subgroup including patients who received adjuvant chemotherapy containing anthracyclines or taxanes, sub-analysis assessment revealed that gemcitabine-based doublets were superior to monotherapy in ORR (HR 1.64, 95% CI 1.26-2.12; P = 0.0002) and TTP (HR 0.71, 95% CI 0.62-0.81; P < 0.00001), but no benefit was observed for OS (HR 0.90, 95% CI 0.79-1.03; P = 0.14). The rates of grade 3 and 4 anemia (HR 2.02, 95% CI 1.35-3.02; P = 0.006), neutropenia (HR 2.33, 95% CI 1.37-3.63; P = 0.01), and thrombocytopenia (HR 8.31, 95% CI 5.00-13.82; P < 0.0001) were significantly higher in the gemcitabine-based arm. CONCLUSIONS The present study suggests that gemcitabine-based chemotherapy was as effective as gemcitabine-free chemotherapy in patients with metastatic breast cancer with increased hematological toxicity. Subgroup analysis indicated that adding gemcitabine to monotherapy might be more effective.

Abstract
Purpose Gemcitabine, a third-generation anticancer agent, has been shown to be active in several solid tumors. High-grade hemorrhage (grade≥3) has been reported with this drug, although the overall risk remains unclear. We conducted a meta-analysis of randomized controlled trials evaluating the incidence and risk of high-grade hemorrhage associated with gemcitabine. Methods Pubmed was searched for articles published from January 1, 1990 to December 31, 2012. Eligible studies included prospective randomized controlled phase II and III trials evaluating gemcitabine-based vs non-gemcitabine-based therapy in patients with solid tumors. Data on high-grade hemorrhage were extracted. Overall incidence rates, relative risk (RR), and 95% confidence intervals (CI) were calculated employing fixed- or random-effects models depending on the heterogeneity of included trials. Results A total of 6433 patients from 20 trials were included. Among patients treated with gemcitabine-based chemotherapy, the overall incidence of high-grade hemorrhage was 1.7% (95%CI: 0.9–3.1%), and the RR of high-grade hemorrhage was 2.727 (95%CI: 1.581–4.702, p<0.001). Exploratory subgroup analysis revealed the highest RR of hemorrhage in non-small-cell lung cancer (NSCLC) patients (RR: 3.234; 95%CI, 1.678–6.233; p<0.001), phase II trials (RR 7.053, 95%CI: 1.591–31.27; p = 0.01), trials reported during 2006–2012 (RR: 3.750; 95%CI: 1.735–8.108, p<0.001) and gemcitabine used as single agent (RR 7.48; 95%CI: 0.78–71.92, p = 0.081). Conclusion Gemcitabine is associated with a significant increase risk of high-grade hemorrhage in patients with solid tumors when compared with non-gemcitabine-based therapy.

Abstract
Background Chemotherapy dose delay and/or reduction lower relative total dose intensity (RTDI) and may affect short- and long-term outcome of metastatic breast cancer (MBC) patients. Methods Based on 933 individual patients' data of from 3 randomized MBC trials using an anthracycline and taxane we examined the impact of RTDI on efficacy and determined the lowest optimal RTDI for MBC patients. Results Median time to disease progression (TTDP) and overall survival (OS) of all patients were 39 and 98 weeks. Overall higher RTDI was correlated with a shorter TTDP (log-rank p = 0.0525 for 85% RTDI cut-off). Proportional hazards assumption was violated, there was an early drop in the TTDP-curve for the high RTDI group. It was explained by the fact that patients with primary disease progression (PDP) do have a high RTDI per definition. Excluding those 114 patients with PDP the negative correlation between RTDI and TTDP vanished. However, non-PDP patients with RTDI-cut-off levels <85% showed a shorter OS than patients with higher RTDI levels (p = 0.0086). Conclusions Optimizing RTDI above 85% appears to improve long-term outcome of MBC patients receiving first-line chemotherapy. Lowering RTDI had no negative influence on short term outcome like OR and TTDP.

Abstract
BACKGROUND Neoadjuvant anthracycline/taxane combinations, with or without gemcitabine, produce pathologic complete responses (pCRs) in 15%-25% of patients. In this multicenter phase II study, we attempted to increase efficacy and decrease toxicity of a 3-drug gemcitabine-containing neoadjuvant regimen by administering dose-dense therapy with pegfilgrastim, and including albumin-bound paclitaxel as the taxane. PATIENTS AND METHODS A total of 123 patients with locally advanced breast cancer were enrolled. Patients were treated with 6 doses of neoadjuvant gemcitabine 2000 mg/m2, epirubicin 50 mg/m2, and albumin-bound paclitaxel 175 mg/m2 intravenously administered at 14-day intervals. Following neoadjuvant chemotherapy, patients underwent either mastectomy or breast conservation surgery; pathologic response to treatment was assessed. Postoperatively, patients received 4 doses of gemcitabine 2000 mg/m2 with albumin-bound paclitaxel 220 mg/m2 at 14-day intervals. Pegfilgrastim 6 mg was administered subcutaneously on day 2 following each dose of chemotherapy. RESULTS A total of 116 patients (95%) completed neoadjuvant chemotherapy and had subsequent surgical resection. Twenty-three patients (20%) had a pCR. The estimated 3-year progression-free survival (PFS) and overall survival rates were 48% and 86%, respectively. Neoadjuvant treatment was well tolerated; only 11% of the patients had grade 3/4 neutropenia, with 1 episode of neutropenic fever. Other grade 3/4 toxicities occurred in < 10% of the patients. CONCLUSION Neoadjuvant biweekly chemotherapy with gemcitabine/epirubicin/albumin-bound paclitaxel with pegfilgrastim is feasible and well tolerated. The pCR rate of 20% and the 3-year PFS rate of 48% are similar to results achieved with other commonly used neoadjuvant regimens.

Abstract
BACKGROUND Supportive care interventions can have a substantial impact on side effects of chemotherapy. Consequently, accurate reporting of such interventions is essential when interpreting clinical trial results. This study determined the prevalence and quality of reporting of supportive care treatment for common chemotherapy-induced toxicities in phase III, breast cancer chemotherapy trials. METHODS A systematic review of phase III trials of breast cancer trials incorporating chemotherapy published in the last 5 years was undertaken. Trials were identified through MEDLINE, EMBASE, BIOSIS, and the Cochrane Library. Supportive treatments evaluated were use of antiemetics, colony-stimulating growth factors, and antibiotics. Reporting quality was rated as "good", "fair", "poor", or "absent" using predetermined criteria. RESULTS Sixty-two trials met inclusion criteria. In 41 studies (66%), details regarding prophylactic antiemetic treatment were not provided. Growth factor use was not reported in 20 trials (32%). Instructions for the use of prophylactic antibiotics were absent in 45 trials (72%). CONCLUSION There are significant deficiencies in reporting of use of prophylactic supportive care agents in breast cancer trials. Omission of supportive care instructions may impact substantially on patient management and health care system expenditure. Recommendations for the type, dose, and frequency of supportive care drugs should be provided and reported on in trials.

Abstract
BACKGROUND Breast cancer becomes lethal when visceral metastases develop. At this stage, anti-cancer treatments aim at relieving symptoms and delaying death without resulting in additional toxicity. On the basis of their differential anti-oxidant defence level, tumour cells can be made more sensitive to chemotherapy than non-tumour cells when membrane lipids are enriched with docosahexaenoic acid (DHA), a peroxidisable and oxidative-stress-inducing lipid of marine origin. METHODS This open-label single-arm phase II study evaluated the safety and efficacy (response rate), as primary end points, of the addition of 1.8 g DHA daily to an anthracycline-based chemotherapy (FEC) regimen in breast cancer patients (n = 25) with rapidly progressing visceral metastases. The secondary end points were time to progression (TTP) and overall survival (OS). RESULTS The objective response rate was 44%. With a mean follow-up time of 31 months (range 2-96 months), the median TTP was 6 months. Median OS was 22 months and reached 34 months in the sub-population of patients (n = 12) with the highest plasma DHA incorporation. The most common grade 3 or 4 toxicity was neutropaenia (80%). CONCLUSION DHA during chemotherapy was devoid of adverse side effects and can improve the outcome of chemotherapy when highly incorporated. DHA has a potential to specifically chemosensitise tumours.

Abstract
BACKGROUND Many systemic nonhormonal regimens have been evaluated across several hundreds of randomized trials in advanced breast cancer. We aimed to quantify the relative merits of these regimens in prolonging survival. METHODS We performed a systematic review of all trials that compared different regimens involving chemotherapy and/or targeted therapy in advanced breast cancer (1973-2007). Regimens were categorized a priori into different treatment types. We performed multiple-treatments meta-analysis and calculated hazard ratios for each treatment category relative to monotherapy with old agents (ie, regimens not including anthracyclines, anthracenediones, vinorelbine, gemcitabine, capecitabine, taxanes, marimastat, thalidomide, trastuzumab, lapatinib, or bevacizumab). RESULTS We identified 370 eligible randomized trials (54,189 patients), of which 172 (31,552 patients) compared different types of treatment. Survival data from 148 comparisons pertaining to 128 of the 172 trials (26,031 patients, 22 different types of treatment) were available for inclusion in the multiple-treatments meta-analysis. Compared with single-agent chemotherapy with old nonanthracycline drugs, anthracycline regimens achieved 22%-33% relative risk reductions in mortality (ie, hazard ratio [HR] for standard-dose anthracycline-based combination: 0.67, 95% credibility interval [CrI] 0.57-0.78). Several newer regimens achieved further benefits (eg, HR [95% CrI] 0.67 [0.55-0.81] for single-drug taxane, 0.64 [0.53-0.78] for combination of anthracyclines with taxane, 0.49 [0.37-0.67] for taxane-based combination with capecitabine or gemcitabine), and similar benefits were seen with several regimens including molecular targeted treatments. Most regimens had very similar efficacy profiles (<5% difference in HR) as first- and subsequent-line therapies. CONCLUSIONS Stepwise improvements in efficacy of chemotherapy and targeted treatments cumulatively have achieved major improvements in the survival of patients with advanced breast cancer. Many options that can be used in first and subsequent lines of therapy have comparable efficacy profiles.

Abstract
OBJECTIVES Progression-free survival (PFS) has not been validated as a surrogate endpoint for overall survival (OS) for anthracycline (A) and taxane-based (T) chemotherapy in advanced breast cancer (ABC). Using trial-level, meta-analytic approaches, we evaluated PFS as a surrogate endpoint. METHODS A literature review identified randomized, controlled A and T trials for ABC. Progression-based endpoints were classified by prospective definitions. Treatment effects were derived as hazard ratios for PFS (HRPFS) and OS (HROS). Kappa statistic assessed overall agreement. A fixed-effects regression model was used to predict HROS from observed HRPFS. Cross-validation was performed. Sensitivity and subgroup analyses were performed for PFS definition, year of last patient recruitment, line of treatment, and constant rate assumption. RESULTS Sixteen A and fifteen T trials met inclusion criteria, producing seventeen A (n = 4,323) and seventeen T (n = 5,893) trial-arm pairs. Agreement (kappa statistic) between the direction of HROS and HRPFS was 0.71 for A (p = .0029) and 0.75 for T (p = .0028). While HRPFS was a statistically significant predictor of HROS for both A (p = .0019) and T (p = .012), the explained variances were 0.49 (A) and 0.35 (T). In cross-validation, 97 percent of the 95 percent prediction intervals crossed the equivalence line, and the direction of predicted HROS agreed with observed HROS in 82 percent (A) and 76 percent (T). Results were robust in sensitivity and subgroup analyses. CONCLUSIONS This meta-analysis suggests that the trial-level treatment effect on PFS is significantly associated with the trial-level treatment effect on OS. However, prediction of OS based on PFS is surrounded with uncertainty.

Abstract
PURPOSE In Her2-postive metastatic breast carcinoma, first-line trastuzumab-based therapy is well established; many centres continue antibody treatment beyond disease progression. In this trial, we evaluated the efficacy and safety of gemcitabine and trastuzumab after earlier exposure to anthracyclines, docetaxel and/or vinorelbine, and trastuzumab. METHODS Twenty-nine consecutive patients were included as eligible. Patients received gemcitabine at a dose of 1,250 mg/m2 on day one and eight, every 21 days. Trastuzumab was administered in three-week cycles. Clinical benefit rate (CBR; CR + PR + SD > or = 6 months) was defined as primary endpoint. RESULTS As of July 2007, all patients are evaluable for toxicity, and 26 for response. Earlier therapies consisted of trastuzumab (100%), anthracyclines (100%), vinorelbine (96.6%), docetaxel (72.4%), and capecitabine (72.4%). 19.2% of patients experienced PR, and SD > or = 6 months was observed in a further 26.9%, resulting in a CBR of 46.2%. Time to progression was median 3 months, and overall survival 17 months. Neutropenia (20.7%), thrombocytopenia (13.8%), and nausea (3.4%) were the only treatment-related adverse events that occurred with grade 3 or 4 intensity. Four patients (13.8%) developed brain metastases while on therapy. CONCLUSIONS While CBR was low when compared to trastuzumab-based first-line therapy, it is higher than what would be expected from gemcitabine monotherapy in a similar setting. Together with the favourable toxicity profile, this regimen appears to be a safe and potentially effective salvage therapy option in a heavily pre-treated population.

Abstract
Many active cytotoxic drugs, given according to a number of different regimens are approved for the treatment of metastatic breast cancer patients. However, these therapies have not changed the outcome of patients affected by this malignancy. As a consequence, the balance between chemotherapy-induced side effects and relief of cancer-related symptoms must be carefully considered in this setting. Gemcitabine is an antimetabolite that is incorporated as a triphosphate into DNA. As a single agent, it yields responses rates ranging from 14% to 37% in chemotherapy-naïve patients and from 12% to 30% in patients previously treated with anthracyclines and/or taxanes. In combination with paclitaxel, it produces a significantly higher response rate (41.4% vs. 26.2%), longer time to progression (6.1 vs. 4 months) and significantly higher overall survival (18.6 vs. 15.8 months) than paclitaxel alone. In addition, a phase III study revealed that gemcitabine plus docetaxel is as effective as capecitabine plus docetaxel, but causes significantly less non-haematologic toxicity. Lastly, in another phase III trial, progression free survival was significantly longer with the combination of gemcitabine plus vinorelbine than with vinorelbine alone (6 vs. 4 months), but without a significant difference in overall survival; the incidence of haematologic toxicity was higher in the group treated with combined therapy. Novel gemcitabine combinations are being investigated in phase II studies.

Abstract
To determine the maximum tolerated doses (MTDs) and dose-limiting toxicities (DLTs) of pegylated liposomal doxorubicin (PLD), paclitaxel (PCX) and gemcitabine (GEM) combination administered biweekly in patients with advanced solid tumours. Twenty-two patients with advanced-stage solid tumours were treated with escalated doses of PLD on day 1 and PCX plus GEM on day 2 (starting doses: 10, 100 and 800 mg m−2, respectively) every 2 weeks. DLTs and pharmacokinetic (PK) parameters of all drugs were determined during the first cycle of treatment. All but six (73%) patients had previously received at least one chemotherapy regimen. The DLT dose level was reached at PLD 12 mg m−2, PCX 110 mg m−2 and GEM 1000 mg m−2 with neutropaenia being the dose-limiting event. Of the 86 chemotherapy cycles delivered, grade 3 and 4 neutropaenia occurred in 20% with no cases of febrile neutropaenia. Non-haematological toxicities were mild. The recommended MTDs are PLD 12 mg m−2, PCX 100 mg m−2 and GEM 1000 mg m−2 administered every 2 weeks. The PK data revealed no obvious drug interactions. Biweekly administration of PLD, PCX and GEM is a well-tolerated chemotherapy regimen, which merits further evaluation in various types of solid tumours.

Abstract
BACKGROUND A systematic review of the evidence for gemcitabine chemotherapy, alone or in combination, in women with metastatic/advanced breast cancer was undertaken in order to determine gemcitabine's role in the first-line and/or second-line or greater setting. METHODS MEDLINE, EMBASE, the American Society of Clinical Oncologists, San Antonio Breast Cancer Symposium proceedings, and the Cochrane Library were searched through September 2006 for randomized controlled trials and non-randomized phase two trials. RESULTS Eighty-three trials were identified, including four randomized phase III trials. All of the phase III trials included first-line patients. Two of the phase III trails demonstrated clinical benefit with gemcitabine-based chemotherapy in terms of superior efficacy or less toxicity while two phase III trials found no clinical benefit based on less efficacy or increased toxicity. Although 78 phase II trials of gemcitabine alone or in combination with other chemotherapy agents were identified, few combinations showed results compelling enough to warrant randomized trials. CONCLUSION Available data do not support the acceptance of gemcitabine as a standard therapeutic option in women with metastatic breast cancer in the third-line or greater setting, nor should it be considered as first-line therapy in anthracycline naïve women. Gemcitabine appears to be most effective when administered with a taxane (docetaxel/paclitaxel) in the first- or second-line setting, with gemcitabine/taxane combinations representing a viable alternative to currently accepted taxane combinations such as capecitabine/docetaxel. There is no evidence at this time to support the use of gemcitabine triplets, given the equal efficacy to anthracycline triplets and the added toxicity.

Abstract
This randomized phase 2 study explored the feasibility of delivering four to six cycles of the dose-intensified regimen FEC-100 (5-fluorouracil, epirubicin, and cyclophosphamide) to elderly patients with stage II-III breast cancer, using pegfilgrastim for neutrophil support. Sixty patients aged 65-77 years received single 6mg doses of pegfilgrastim on day 2 of FEC-100, either as primary prophylaxis (all cycles: PP), or as secondary prophylaxis (all cycles following a neutropenic event: SP). Neutropenic events (a composite endpoint that included grade 3 neutropenia+fever, grade 4 neutropenia, infectious complication requiring systemic anti-infectives and chemotherapy dose delay/reduction) occurred in 24/30 (80%) of the PP and 21/29 (72%) of the SP group in the first cycle. Most patients received all chemotherapy cycles at full dose on schedule (26/30 [87%] PP; 20/29 [69%] SP). These data indicate that delivery of FEC-100 is feasible with pegfilgrastim support in elderly breast cancer patients.

Abstract
PURPOSE To evaluate the efficacy of gemcitabine-based chemotherapy, particularly in patients with anthracycline- and taxane-pretreated 2(nd)-line or greater metastatic breast cancer, and to compare gemcitabine monotherapy (G) with two gemcitabine-based doublets, gemcitabine/vinorelbine (GV) and gemcitabine/capecitabine (GX). MATERIALS AND METHODS Of 124 consecutive patients who progressed after anthracycline- and taxane-containing chemotherapy, 58 received G alone, 38 received GV, and 28 received GX; their outcomes were analyzed retrospectively. RESULTS The median number of prior metastatic chemotherapy regimens was 2 (range 0 approximately 4). Visceral metastases were observed in 65 patients (51.4%). The overall response rate was 19.3% (21 partial responses). After a median follow-up period of 21.4 months, the overall survival was 7.6 months (95% CI: 5.5 approximately 9.6 months) and the median time to progression was 3.1 months (95% CI: 2.0 approximately 4.2 months). Compared with monotherapy (G), combination therapy with vinorelbine or capecitabine (GV/GX) was associated with a significantly higher response rate (8.2% vs. 28.3%, p=0.008) and a significantly longer median time to progression (2.8 vs. 3.5 months; p=0.028), but overall survival did not differ between the groups (7.4 vs. 8.2 months, respectively; p=0.54). Most of the adverse treatment-related events were mild to moderate in intensity. The most common adverse event was hematologic toxicity. Multivariate analysis showed that poor performance status and a short disease-free interval were independent prognostic factors for impaired overall survival. CONCLUSIONS The combination of gemcitabine with vinorelbine or capecitabine was an active and well-tolerated treatment option for taxane- and anthracycline-pretreated 2(nd)-line or greater metastatic breast cancer patients, and gemcitabine-based doublets were more beneficial than gemcitabine monotherapy in alleviating symptoms for these patients.

Abstract
Chemotherapy-induced neutropenia is not only a major risk factor for infection-related morbidity and mortality, but is also a significant dose-limiting toxicity in cancer treatment. Patients developing severe (grade 3/4) or febrile neutropenia (FN) during chemotherapy frequently receive dose reductions and/or delays to their chemotherapy. This may impact on the success of treatment, particularly when treatment intent is either curative or to prolong survival. The incidence of severe or FN can be reduced by prophylactic treatment with granulocyte-colony stimulating factors (G-CSFs), such as filgrastim, lenograstim or pegfilgrastim. However, the use of G-CSF prophylactic treatment varies widely in clinical practice, both in the timing of therapy and in the patients to whom it is offered. While several academic groups have produced evidence-based clinical practice guidelines in an effort to standardise and optimise the management of FN, there remains a need for generally applicable, European-focused guidelines. To this end, we undertook a systematic literature review and formulated recommendations for the use of G-CSF in adult cancer patients at risk of chemotherapy-induced FN. We recommend that patient-related adverse risk factors such as elderly age (>or=65 years), be evaluated in the overall assessment of FN risk prior to administering each cycle of chemotherapy. In addition, when using a chemotherapy regimen associated with FN in >20% patients, prophylactic G-CSF is recommended. When using a chemotherapy regimen associated with FN in 10-20% patients, particular attention should be given to patient-related risk factors that may increase the overall risk of FN. In situations where dose-dense or dose-intense chemotherapy strategies have survival benefits, prophylactic G-CSF support is recommended. Similarly, if reductions in chemotherapy dose intensity or density are known to be associated with a poor prognosis, primary G-CSF prophylaxis may be used to maintain chemotherapy. Finally, studies have shown that filgrastim, lenograstim and pegfilgrastim have clinical efficacy and we recommend the use of any of these agents to prevent FN and FN-related complications, where indicated.

Abstract
BACKGROUND Patients with metastatic breast cancer are frequently treated with anthracyclines and taxanes, which are among the most active agents in this disease. Gemcitabine is an interesting candidate for a three-drug combination because of its different mechanism of action and non-overlapping toxicity with respect to the other two drugs. We aimed to evaluate the activity and toxicity of the GAT (gemcitabine, doxorubicin and paclitaxel) regimen, derived from experimental preclinical studies, as first-line chemotherapy in patients with stage IIIB-IV breast cancer. METHODS Patients with locally advanced or metastatic breast cancer and at least one bidimensionally measurable lesion were included in the present study. Adequate bone marrow reserve, normal cardiac, hepatic and renal function, and an ECOG performance status of 0 to 2 were required. Only prior adjuvant non anthracycline-based chemotherapy was permitted. Treatment consisted of doxorubicin 50 mg/m2 on day 1, paclitaxel 160 mg/m2 on day 2 and gemcitabine 800 mg/m2 on day 6, repeated every 21-28 days. RESULTS Thirty-three consecutive breast cancer patients were enrolled onto the trial (7 stage IIIB and 26 stage IV). All patients were evaluable for toxicity and 29 were assessable for response. A total of 169 cycles were administered, with a median of 6 cycles per patient (range 1-8 cycles). Complete and partial responses were observed in 6.9% and 48.3% of patients, respectively, for an overall response rate of 55.2%. A response was reported in all metastatic sites, with a median duration of 16.4 months. Median time to progression and overall survival were 10.2 and 36.4 months, respectively. The most important toxicity was hematological, with grade III-IV neutropenia observed in 69% of patients, sometimes requiring the use of granulocyte colony-stimulating factor (27%). Non hematological toxicity was rare and mild. One patient died from sepsis during the first treatment cycle before the administration of gemcitabine. CONCLUSION The strong synergism among the three drugs found in the preclinical setting was confirmed in terms of both clinical activity and hematological toxicity. Our results seem to indicate that the GAT regimen is effective in anthracycline-naïve metastatic breast cancer and provides a feasible chemotherapeutic option in this clinical setting.

Abstract
Surgical resection remains the foundation of curative therapy in early stage non-small cell lung cancer (NSCLC). Recent evidence from several randomized trials has shown that adjuvant chemotherapy regimens of platinum-based agents plus third-generation cytotoxic agents improve survival rates in this population of patients. Despite the use of adjuvant chemotherapy, many patients will suffer a relapse, typically systemic, and be candidates for subsequent therapies. This represents a new population of patients with NSCLC. To date, there are no published trials that evaluate prognostic factors or therapeutic outcomes in these patients. Although therapeutic paradigms have been established in patients who present with de novo metastatic NSCLC, it is not clear whether these paradigms are successful for patients who relapse following platinum-based adjuvant chemotherapy. The influence of time from the previous adjuvant exposure is likely to be as important as it seems to be in other solid tumors. However, dedicated clinical research has not yet established this paradigm in NSCLC and the influence this should have on the choice of subsequent therapy is unknown. The nature of the prior adjuvant exposure may also play a role in the choice of subsequent therapy. This has implications for the design of future trials in advanced NSCLC as these patients may or may not have the same natural history as the de novo metastatic NSCLC patient. Future clinical trials are required to address these issues as well as the biologic heterogeneity that likely exists between patients who are seemingly cured by surgery, relapse early (<1 year), or at later times following adjuvant therapy.

Abstract
Anthracyclines and the taxanes are now used earlier in the course of therapy for metastatic breast cancer, and increasingly as part of adjuvant treatment. Accordingly, novel therapies are warranted, including alternatives to anthracyclines and combination strategies in the setting of disease resistance to or disease progression after anthracycline and taxane therapy. Gemcitabine is part of this strategy. The gemcitabine/paclitaxel combination has emerged as part of a new standard of combination therapy for advanced breast cancer, based on phase III data showing superiority of this combination over paclitaxel alone in the first-line therapy setting. Gemcitabine alone, or in combination with paclitaxel and other agents, is also undergoing evaluation in other settings including the refractory metastatic setting, as part of management of patients with HER2-positive disease, and also as part of adjuvant therapy for breast cancer.

Abstract
Surrogate markers may help predict the effects of first-line treatment on survival. This metaregression analysis examines the relationship between several surrogate markers and survival in women with advanced breast cancer after receiving first-line combination anthracycline chemotherapy 5-fluorouracil, adriamycin and cyclophosphamide (FAC) or 5-fluorouracil, epirubicin and cyclophosphamide (FEC) . From a systematic literature review, we identified 42 randomised trials. The surrogate markers were complete or partial tumour response, progressive disease and time to progression. The treatment effect on survival was quantified by the hazard ratio. The treatment effect on each surrogate marker was quantified by the odds ratio (or ratio of median time to progression). The relationship between survival and each surrogate marker was assessed by a weighted linear regression of the hazard ratio against the odds ratio. There was a significant linear association between survival and complete or partial tumour response (P<0.001, R2=34%), complete tumour response (P=0.02, R2=12%), progressive disease (P<0.001, R2=38%) and time to progression (P<0.0001, R2=56%); R2 is the proportion of the variability in the treatment effect on survival that is explained by the treatment effect on the surrogate marker. Time to progression may be a useful surrogate marker for predicting survival in women receiving first-line anthracycline chemotherapy and could be used to estimate the survival benefit in future trials of first-line chemotherapy compared to FAC or FEC. The other markers, tumour response and progressive disease, were less good.
