NPJ Breast Cancer 2023; 9:28. [PMID: 37072437 PMCID: PMC10113253 DOI: 10.1038/s41523-023-00522-5] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2022] [Accepted: 03/10/2023] [Indexed: 04/20/2023] Open
Abstract
In this phase I study, the safety, pharmacokinetics, and antitumour activity of the HER2-targeted antibody-drug conjugate A166 were evaluated in patients with HER2-expressing advanced solid tumours. Patients with advanced solid tumours refractory to standard therapies received A166 at doses of 0.1, 0.3, 0.6, 1.2, 2.4, 3.6, 4.8 or 6.0 mg/kg Q3W in a standard "3 + 3" design. Dose cohorts were expanded at 4.8 and 6.0 mg/kg Q3W. Primary endpoints were assessment of the safety and tolerability of A166 and identification of the maximum tolerated dose or recommended phase II dose. In total, 81 patients were enroled and received A166 (n = 1 for 0.1 mg/kg; n = 3 for each of 0.3, 0.6, 1.2, 2.4 and 3.6 mg/kg doses; n = 27 for 4.8 mg/kg; n = 38 for 6.0 mg/kg). No dose-limiting toxicity or drug-related deaths occurred. The most common treatment-related adverse events at grade 3 or higher were corneal epitheliopathy (30.9%), blurred vision (18.5%), dry eyes (7.4%), and peripheral sensory neuropathy (6.2%). The Cmax and area under the curve of Duo-5, its free payload, were approximately 0.1% and 0.2% of those of the ADC, respectively. For all assessable HER2-positive breast cancer patients enroled in the 4.8 mg/kg and 6.0 mg/kg cohorts, the corresponding ORRs were 73.9% (17/23) and 68.6% (24/35), respectively, and the median PFS was 12.3 and 9.4 months, respectively. A166 has a recommended phase II dose of 4.8 mg/kg Q3W, manageable toxicity, good stability in the circulation and promising antitumour activities in HER2-positive breast cancer patients.

Docetaxel for Breast Cancer Treatment-Side Effects on Ocular Surface, a Systematic Review. Processes (Basel) 2021.

Abstract
Docetaxel is a very effective chemotherapeutic agent for the treatment of metastatic or locally advanced breast cancer. Epiphora (hyperlacrimation) has been shown to be the most common eye condition in patients receiving docetaxel-based chemotherapy. This symptom does not decrease visual acuity, but decreases the quality of life. Daily activities (reading, working on the computer, watching TV, and so on) are affected, with patients complaining about an alteration of daily life with the appearance of this symptom. The mechanism by which epiphora occurs is considered to be the canalicular stenosis, but the trials on the subject failed to reach statistical significance. The objective of this scoping review is to determine whether there is a treatment regimen-dependent relationship between docetaxel administration and the presence of epiphora in women with breast cancer. The inclusion criteria were met by 10 trials, from which one was excluded owing to data selection biases. Accordingly, nine studies were evaluated quantitatively and qualitatively in the present review. We included subjects with docetaxel as single treatment or docetaxel in combination with other chemotherapy compounds. The occurrence of epiphora among subjects treated with docetaxel, regardless of the therapeutic regimen used, was statistically significant (p = 0.005). The proportion of patients with epiphora after weekly administration of docetaxel (54 out of 131 subjects, 41.22%) was different compared with that of those who received docetaxel at three week intervals (112 out of 325 subjects, 34.15%), but the difference between the two was not statistically significant (p = 0.732). The present study demonstrates that epiphora occurs more frequently in patients receiving weekly docetaxel-based chemotherapy than those taking the three-weekly regimen, but the difference is not statistically significant. Ophthalmologic assessment of all patients starting this treatment is recommended. The causal relationship between canalicular stenosis and epiphora is not fully elucidated as long as this ocular symptom occurs in women who do not have stenosis of the lacrimal system. Further well-designed trials are required to bring new insights into the mechanisms of epiphora pathogenesis in subjects treated with docetaxel.

Abstract
Background: Cancer is the second leading cause of death globally. Up to 86% of advanced cancer patients experience significant pain, while 10-20% live in chronic pain. Besides, increasing prescription of opioids resulted in 33,000 deaths in the US in 2015. Both reduce patients’ functional status and quality of life. While cancer survival rates are increasing, therapeutic options for chronic opioid refractory pain are still limited. Esketamine is the s-enantiomer of ketamine, with superior analgesic effect and less psychotomimetic side effects. Intranasal esketamine was approved by the FDA for treatment-resistant depression. However, its use in chronic cancer pain has never been tested. Therefore, we propose a phase II, randomized, placebo-controlled trial to evaluate the efficacy and safety of intranasal esketamine in chronic opioid refractory cancer pain. Methods and analysis: We will recruit 120 subjects with chronic opioid refractory pain, defined as pain lasting more than 3 months despite optimal therapy with high dose opioids (>60 mg morphine equivalent dose/day) and optimal adjuvant therapy. Subjects will be randomized into two groups: intranasal esketamine (56mg) and placebo. Treatment will be administered twice a week for four consecutive weeks. The primary outcome is defined as reduction in the Numeric Pain Rating Scale (NPRS) after first application. Secondary outcomes include NPRS reduction after four weeks, the number of daily morphine rescue doses, functional status and satisfaction, and depression. Conclusion: This study may extend therapeutic options in patients with chronic pain, thus improving their quality of life and reducing opioid use. Trial registration: Clinical Trials.gov,

Abstract
Antibody-drug conjugates (ADCs) are complex engineered therapeutics consisting of monoclonal antibodies, directed toward tumor-associated antigens, to which highly potent cytotoxic agents are attached using chemical linkers. This targeted drug delivery strategy couples the precision of the antibody targeting moiety with the cytocidal activity of the payload, which is generally too toxic on its own to be systemically administered. In this manner, ADCs confer a means to reduce off-target toxicities in patients by limiting the exposure of normal tissues to the payload, thus broadening the potential therapeutic window compared with traditional chemotherapy. The pace of ADC development is accelerating, with the number of investigational agents in human trials having more than tripled over the past 5 years, underscoring the enthusiasm for this transformative approach to cancer treatment. Here, we review the key structural elements of ADC design (antibody, linker, and payload), highlighting critical aspects and technological advances that have affected the clinical effectiveness of this class of biopharmaceuticals. The ADC field continues to evolve, including ongoing efforts aimed at improving target selection, developing payloads with varied mechanisms of action and increased potency, designing innovative bioconjugation strategies, as well as maximizing efficacy and tolerability in patients. An overview of the current clinical trial landscape is provided, with emphasis on the clinical experience of the four ADCs to have received regulatory approval to date, as well as additional promising candidates currently in late-stage clinical development in both solid tumor and hematological malignancies.

Abstract
Background Plocabulin (PM060184) is a novel marine-derived microtubule inhibitor that acts as an antitumor agent. This first-in-human study evaluated dose-limiting toxicities (DLT) to define the maximum tolerated dose (MTD) and phase II recommended dose (RD) of plocabulin given as a 10-min infusion on Day (D) 1, D8 and D15 every four weeks. Patients and methods Forty-four patients with advanced solid tumors received plocabulin following an accelerated titration design. Results Plocabulin was escalated from 1.3 mg/m2 to 14.5 mg/m2, which was defined as the MTD. No RD was confirmed, because frequent dose delays and omissions resulted in low relative dose intensity (66%) at the 12.0 mg/m2 expansion cohort. The main DLT was grade 3 peripheral sensory neuropathy (PSN); other DLTs were grade 4 tumor lysis syndrome, grade 4 cardiac failure and grade 3 myalgia. Toxicities were mainly mild to moderate, and included abdominal pain, myalgia, fatigue, nausea, and vomiting. Myelosuppression was transient and manageable. Plocabulin had a half-life of ~4 h and a wide diffusion to peripheral tissues. Antitumor response was observed in cervix carcinoma and heavily pretreated metastatic non-small cell lung cancer patients, and disease stabilization (≥3 months) in patients with colorectal, thymic, gastrointestinal stromal and breast tumors, among others. The clinical benefit rate was 33%. Conclusion The main DLT of plocabulin was PSN, as anticipated for a tubulin-binding agent. Since encouraging antitumor activity was observed, efforts to improve toxicity and to find the RD were planned in other trials evaluating D1&D8 and D1-D3 plus D15-D17 schedules.

Abstract
Taxanes are a group of cytotoxic anti-cancer agents used in the treatment of solid tumours. The neurotoxic adverse effects of docetaxel and paclitaxel, including optic neuropathy, are well known. Cabazitaxel is a new generation taxane showing lesser drug resistance when compared with previous ones. Optic atrophy due to the use of cabazitaxel has not been previously reported. Herein, we report a patient with prostate cancer who developed optic atrophy after cabazitaxel treatment.

Abstract
Aims and background We previously designed and tested combinations made up of the CMF agents, two at a time by rotation, and of doxorubicin or epirubicin. The present study was aimed to similarly test new combinations made up of the CMF agents, two at a time by rotation, and paclitaxel or docetaxel. Methods The doses of each taxane were escalated with the objective of reaching at least a single dose level of 90 mg/m2 of paclitaxel and 45 mg/m2 of docetaxel on days 1 and 8 of each four-week cycle. Thirty-two patients with advanced breast carcinoma were randomized to receive increasing doses of paclitaxel (45, 65, 80, 90 and 100 mg/m2) or docetaxel (30, 35, 40, 45 and 50 mg/m2) together with the CMF agents at the same dose as that used in the conventional regimen. Each dose level was administered to a triplet of patients. No direct comparison of the two taxanes was made. Results The fourth dose level was reached for paclitaxel and docetaxel. The most important toxicities were grade 4 neutropenia and grade 1-2 nausea/vomiting and stomatitis. The objective response rate, assessed only after the third cycle at any dose level, was 31% (95% CI, 15-47%). Conclusions The combinations of the CMF agents (two at a time in rotation) with paclitaxel (90 mg/m2) or docetaxel (45 mg/m2) on days 1 and 8 of each four-week cycle are feasible and lead to definite signs of therapeutic activity, and the side effects are generally mild. Further studies are therefore warranted.

Abstract
AIMS AND BACKGROUND Sequential docetaxel and gemcitabine following initial docetaxel plus epirubicin or vinorelbine association could be worthwhile as first-line treatment of metastatic breast cancer. METHODS Fifty-eight patients entered a phase II study that included two sequential phases. In the first phase, 36 and 22 patients previously unexposed or exposed to adjuvant anthracyclines received the association of docetaxel (75 mg/m2, day 1) with epirubicin (75 mg/m2, day 1) or vinorelbine (20 mg/m2, days 1 and 5), respectively, every 21 days for 4 courses. In the second phase, patients who had a response (R) or stable disease (SD) received docetaxel (35 mg/m2) and gemcitabine (800 mg/m2) on days 1, 8 and 15 every 28 days for 4 courses. RESULTS In the first phase, grade > or = III neutropenia occurred in 51% and 37% of patients during docetaxel-epirubicin and docetaxel-vinorelbine, respectively. In the second phase, it occurred in the 27% and 15% of patients initially treated with docetaxel-epirubicin and docetaxel-vinorelbine, respectively. On an intention to treat basis, the complete (CR) + partial response (PR) rate to the first phase was 71%, and 22% of patients had SD, without a significant difference between the docetaxel-epirubicin and docetaxel-vinorelbine arms. After the second phase, the CR + PR rate was 65%, and 14% of patients had SD. Median time to progression and survival were 12.1 and 22.0 months, respectively, without a significant difference between patients initially treated with docetaxel-epirubicin and docetaxel-vinorelbine. CONCLUSIONS Following an initial docetaxel-based treatment, weekly docetaxel and gemcitabine maintains high percentages of R and SD, with improved toxicity. Survival was similar in patients previously untreated and treated with adjuvant anthracyclines.

Abstract
Controlling effects of drugs administered in combination is particularly challenging with a densified regimen because of life-threatening hematological toxicities. We have developed a mathematical model to optimize drug dosing regimens and to redesign the dose intensification-dose escalation process, using densified cycles of combined anticancer drugs. A generic mathematical model was developed to describe the main components of the real process, including pharmacokinetics, safety and efficacy pharmacodynamics, and non-hematological toxicity risk. This model allowed for computing the distribution of the total drug amount of each drug in combination, for each escalation dose level, in order to minimize the average tumor mass for each cycle. This was achieved while complying with absolute neutrophil count clinical constraints and without exceeding a fixed risk of non-hematological dose-limiting toxicity. The innovative part of this work was the development of densifying and intensifying designs in a unified procedure. This model enabled us to determine the appropriate regimen in a pilot phase I/II study in metastatic breast patients for a 2-week-cycle treatment of docetaxel plus epirubicin doublet, and to propose a new dose-ranging process. In addition to the present application, this method can be further used to achieve optimization of any combination therapy, thus improving the efficacy versus toxicity balance of such a regimen.

Abstract
BACKGROUND Taxanes are drugs used in various chemotherapeutical protocols to treat solid tumors. They have multiple systemic adverse effects, such as bone marrow suppression, alopecia, nausea, and vomiting, and may rarely cause ocular symptoms. In the past decade, a few reported cases have shown the occurrence of a cystoid macular edema with significant visual loss after the use of a taxane-based chemotherapy. The aim of this study was to compare the central macular thickness (CMT) before and after the initiation of a taxane-based therapy in visually asymptomatic patients and to elucidate the possible impact of these drugs on the vision of cancer patients. METHODS Patients with a confirmed diagnosis of a solid tumor were screened for any ophthalmic disease before inclusion and had a baseline macular spectral domain optical coherence tomography (OCT; RTVue-100; Optovue Inc., Fremont, CA, USA) before the initiation of a taxane-based chemotherapy according to different protocols, such as 4EC-4T, 3FEC/3T, or 4TC. OCT was repeated after 4 cycles (or 3 months) of treatment, and CMT was compared to baseline. Patients presenting diabetic retinopathy, age-related macular degeneration or any condition that causes macular edema confirmed by ophthalmic examination were excluded. RESULTS Fifty eyes of 25 patients were included; 92% of the subjects were female with a mean age of 48.52 years, 88% were diagnosed with breast cancer, 8% with esophageal cancer, and 4% with ovarian cancer. Docetaxel was the taxane administered to 92% of the patients. The received dose of docetaxel ranged between 110 and 160 mg. The other patients had paclitaxel in their protocols. No significant macular edema or drop in visual acuity were noted in any patient. Nevertheless, the mean CMT was found to be increased, particularly in the parafoveal and perifoveal areas (mean difference of +2.22 μm; p = 0.001). CONCLUSION Taxane-based chemotherapy regimens seem to increase macular thickness, with a relative sparing of the fovea, in patients without significant macular edema. Further research is required to better explain the pathophysiology and possible impact of this phenomenon.

Abstract
Docetaxel is a second-generation taxane and is used clinically as an anti-neoplastic agent in cancer chemotherapy via an anti-mitotic mechanism. Its efficacy is limited to a narrow therapeutic window. Inappropriately high concentrations may cause erythema, fluid retention, nausea, diarrhea, and neutropenia. As a result, dosing recommendations have changed from high dosage loading every 3 weeks to lower dosage loading weekly. We describe a method that can be used for therapeutic drug monitoring of docetaxel levels using turbulent flow liquid chromatography electrospray tandem mass spectrometry (TFC-HPLC-ESI-MS/MS). The method is rapid, requiring only 6.3 min per analytical run following a simple protein crash. The method requires only 100 μL of serum. Concentrations of docetaxel were quantified by a calibration curve relating the peak-area ratio of docetaxel to a deuterated internal standard (docetaxel-D9). The method was linear from 7.8 to 1000 ng/mL, with imprecision ≤6.2 %.

Abstract
OBJECTIVES To date, no second-line chemotherapy regimen for esophageal squamous cell carcinoma (SCC) has been established. This clinical trial aimed to assess the optimum dose of docetaxel plus nedaplatin (cis-diammine-glycolate platinum) as second-line chemotherapy. METHODS Patients with metastatic or recurrent esophageal SCC after treatment with cisplatin plus 5-fluorouracil received docetaxel (50 or 60 mg/m) plus nedaplatin (70 mg/m²) on day 1 every 4 weeks. The recommended dose was based on dose-limiting toxicities defined during the first cycle. RESULTS From February 2009 to November 2011, 9 patients were enrolled in the study. Their median age was 62 years (range, 58 to 72 y). Six patients had undergone radiotherapy and 4 had undergone surgical resection of primary lesions. Dose-limiting toxicities were observed in 2 patients at dose level 1 (60 mg/m² docetaxel, 70 mg/m² nedaplatin) but not at dose level 0 (50 mg/m² docetaxel, 70 mg/m nedaplatin). Thus, the maximum tolerated dose was established at dose level 1. No severe nonhematological toxicity was observed. No patient achieved complete response, but 2 (22%; 95% confidence interval, 0%-49%) achieved partial response and 3 had stable disease. Median progression-free and overall survival times were 2.1 and 9.5 months, respectively. CONCLUSIONS Docetaxel plus nedaplatin chemotherapy seems to be a safe and feasible second-line regimen for the treatment of esophageal SCC. We recommend the administration of 50 mg/m² docetaxel (day 1) plus 70 mg/m² nedaplatin (day 1) every 4 weeks in a phase II study.

Abstract
This article reviews ocular adverse events (AEs) reported in association with administration of antibody-drug conjugates (ADCs) in human clinical trials. References reporting ocular toxicity or AEs associated with ADCs were collected using online publication searches. Articles, abstracts, or citations were included if they cited ocular toxicities or vision-impairing AEs with a confirmed or suspected association with ADC administration. Twenty-two references were found citing ocular or vision-impairing AEs in association with ADC administration. All references reported use of ADCs in human clinical trials for treatment of various malignancies. The molecular target and cytotoxic agent varied depending on the ADC used. Ocular AEs affected a diversity of ocular tissues. The most commonly reported AEs involved the ocular surface and included blurred vision, dry eye, and corneal abnormalities (including microcystic corneal disease). Most ocular AEs were not severe (≤ grade 2) or dose limiting. Clinical outcomes were not consistently reported, but when specified, most AEs improved or resolved with cessation of treatment or with ameliorative therapy. A diverse range of ocular AEs are reported in association with administration of ADCs for the treatment of cancer. The toxicologic mechanism(s) and pathogenesis of such events are not well understood, but most are mild in severity and reversible. Drug development and medical professionals should be aware of the clinical features of these events to facilitate early recognition and intervention in the assessment of preclinical development programs and in human clinical trials.

Abstract
There is growing recognition of the important role of metronomic chemotherapy in cancer treatment. On the basis of their unique antiangiogenic effects, we tested the efficacy of nab-paclitaxel, which stimulates thrombospondin-1, and topotecan, which inhibits hypoxia-inducible factor 1-α, at metronomic dosing for the treatment of ovarian carcinoma. In vitro and in vivo SKOV3ip1, HeyA8, and HeyA8-MDR (taxane-resistant) orthotopic models were used to examine the effects of metronomic nab-paclitaxel and metronomic topotecan. We examined cell proliferation (Ki-67), apoptosis (cleaved caspase-3), and angiogenesis (microvessel density, MVD) in tumors obtained at necropsy. In vivo therapy experiments demonstrated treatment with metronomic nab-paclitaxel alone and in combination with metronomic topotecan resulted in significant reductions in tumor weight (62% in the SKOV3ip1 model, P < 0.01 and 96% in the HeyA8 model, P < 0.03) compared with vehicle (P < 0.01). In the HeyA8-MDR model, metronomic monotherapy with either cytotoxic agent had modest effects on tumor growth, but combination therapy decreased tumor burden by 61% compared with vehicle (P < 0.03). The greatest reduction in MVD (P < 0.05) and proliferation was seen in combination metronomic therapy groups. Combination metronomic therapy resulted in prolonged overall survival in vivo compared with other groups (P < 0.001). Tube formation was significantly inhibited in RF-24 endothelial cells exposed to media conditioned with metronomic nab-paclitaxel alone and media conditioned with combination metronomic nab-paclitaxel and metronomic topotecan. The combination of metronomic nab-paclitaxel and metronomic topotecan offers a novel, highly effective therapeutic approach for ovarian carcinoma that merits further clinical development.

Abstract
PURPOSE To report outer retinal disruption and uveal effusion after gemcitabine and docetaxel combination therapy. CASE REPORT A 78-year-old woman presented with blurry vision after two cycles of gemcitabine and docetaxel combination chemotherapy for stage IV sarcoma. At presentation, visual acuity was finger counting and 20/25 in the right and left eyes, respectively. Slit-lamp examination and B-scan ultrasonography revealed severe uveal effusion in the right eye and choroidal folds in the left eye. Spectral domain optical coherence tomography showed disruption of photoreceptor inner segment ellipsoid band in the right eye. The patient was monitored weekly with ophthalmic examination and B-scan ultrasonography, while continuing with gemcitabine monotherapy. At 8 weeks follow-up, uveal effusion improved considerably and visual acuity was 20/40 and 20/20 in the right and left eyes, respectively. CONCLUSIONS Uveal effusion and outer retinal disruption were reported after gemcitabine and docetaxel chemotherapy. Early detection and close ophthalmic monitoring may allow concurrent cancer treatment and prevention of possible chemotherapy-induced ocular side effects.

Abstract
PURPOSE Despite the widespread use of steroid prophylaxis schedules for breast cancer patients receiving docetaxel chemotherapy, questions still exist regarding their optimal use. We surveyed health care providers and patients about their experiences with steroid prophylaxis. METHODS Two questionnaires were developed and circulated. One was presented to health care providers (chemotherapy nurses, pharmacists and medical oncologists) involved in the treatment of breast cancer and the second to patients who had received docetaxel chemotherapy for early stage breast cancer. RESULTS The health care providers' questionnaire was completed by 184 of 698 invitees: 92/171 (53.8 %) chemotherapy nurses, 56/284 (19.7 %) pharmacists and 36/243 (14.8 %) medical oncologists (overall response rate 26.4 %). Two steroid schedules were found to be the most commonly used: dexamethasone 8 mg BID for 6 doses, with either 3 (79 %) or 2 (11 %) doses taken before docetaxel administration. Suboptimal adherence to steroid premedication had been experienced by 98 % (177/181) of practitioners. Despite the presence of local treatment protocols in 65 % (119/183) of practitioners' institutions, 10 different strategies were commonly used when steroid premedication was taken incorrectly. The patients' questionnaire was completed by 72/87 (82.3 %) invitees. Respondents reported correctly taking their premedication 99 % (70/71) of the time. Patients felt steroids frequently caused side effects, the most common being sleep disturbance (35/72 = 49 %) and skin toxicity (16/72 = 22 %). CONCLUSION Suboptimal adherence to steroid premedication prior to docetaxel administration is a common clinical challenge. There appears to be discordance between the practitioner and the patient experience. A single, universally accepted and used protocol for both pre- and post-medication and management when premedication is not taken as prescribed could improve adherence.

Abstract
BACKGROUND A prospective, multicenter trial was undertaken to assess the activity, safety, and quality of life of nanoparticle albumin-bound paclitaxel (nab-paclitaxel) as second-line chemotherapy in HER2-negative, taxane-pretreated metastatic breast cancer (MBC). PATIENTS AND METHODS Fifty-two women with HER2-negative MBC who were candidates for second-line chemotherapy for the metastatic disease were enrolled and treated at three centers in Northern Italy. All patients had previously received taxane-based chemotherapy in the adjuvant or first-line metastatic setting. Single-agent nab-paclitaxel was given at the dose of 260 mg/m(2) as a 30-minute intravenous infusion on day 1 each treatment cycle, which lasted 3 weeks, in the outpatient setting. No steroid or antihistamine premedication was provided. Treatment was stopped for documented disease progression, unacceptable toxicity, or patient refusal. RESULTS All of the enrolled patients were evaluable for the study endpoints. The objective response rate was 48% (95% CI, 31.5%-61.3%) and included complete responses from 13.5%. Disease stabilization was obtained in 19 patients and lasted >6 months in 15 of them; the overall clinical benefit rate was 77%. The median time to response was 70 days (range 52-86 days). The median progression-free survival time was 8.9 months (95% CI, 8.0-11.6 months, range 5-21+ months). The median overall survival point has not yet been reached. Toxicities were expected and manageable with good patient compliance and preserved quality of life in patients given long-term treatment. CONCLUSION Our results showed that single-agent nab-paclitaxel 260 mg/m(2) every 3 weeks is an effective and well tolerated regimen as second-line chemotherapy in HER2-negative, taxane-pretreated MBC patients, and that it produced interesting values of objective response rate and progression-free survival without the concern of significant toxicity. Specifically, the present study shows that such a regimen is a valid therapeutic option for that 'difficult to treat' patient population represented by women who at the time of disease relapse have already received the most active agents in the adjuvant and/or metastatic setting (ie, conventional taxanes).

Abstract
Cytochrome 450 (CYP450) designates a group of enzymes abundant in smooth endoplasmic reticulum of hepatocytes and epithelial cells of small intestines. The main function of CYP450 is oxidative catalysis of various endogenous and exogenous substances. CYP450 are implicated in phase I metabolism of 80% of drugs currently in use, including anticancer drugs. They are also involved in synthesis of various hormones and influence hormone-related cancers. CYP450 genes are highly polymorphic and their variants play an important role in cancer risk and treatment. Association studies and meta-analyses have been performed to decipher the role of CYP450 polymorphisms in cancer susceptibility. Cancer treatment involves multimodal therapies and evaluation of CYP450 polymorphisms is necessary for pharmacogenetic assessment of anticancer therapy outcomes. In addition, CYP450 inhibitors are being evaluated for improved pharmacokinetics and oral formulation of several anticancer drugs.

Abstract
BACKGROUND Although antineoplastic agents are critical in the treatment of cancer, they can potentially cause hypersensitivity reactions that can have serious consequences. When such a reaction occurs, clinicians can either continue the treatment, at the risk of causing a severe or a potentially fatal anaphylactic reaction, or stop the treatment, although it might be the only one available. The objective of the present work was to evaluate the effectiveness of methods used to prevent and treat hypersensitivity reactions to platinum- or taxane-based chemotherapy and to develop evidence-based recommendations. METHODS The scientific literature published to December 2013, inclusive, was reviewed. RESULTS Premedication with antihistamines, H2 blockers, and corticosteroids is not effective in preventing hypersensitivity reactions to platinum salts. However, premedication significantly reduces the incidence of hypersensitivity to taxanes. A skin test can generally be performed to screen for patients at risk of developing a severe reaction to platinum salts in the presence of grade 1 or 2 reactions, but skin testing does not appear to be useful for taxanes. A desensitization protocol allows for re-administration of either platinum- or taxane-based chemotherapy to some patients without causing severe hypersensitivity reactions. CONCLUSIONS Several strategies such as premedication, skin testing, and desensitization protocols are available to potentially allow for administration of platinum- or taxane-based chemotherapy to patients who have had a hypersensitivity reaction and for whom no other treatment options are available. Considering the available evidence, the Comité de l'évolution des pratiques en oncologie made recommendations for clinical practice in Quebec.

Abstract
Angiosarcoma of the face and scalp of the elderly frequently recurs locally, metastasizes early despite various treatments, and has a poor prognosis. We describe a patient who had angiosarcoma of the scalp with pulmonary metastasis. Local recurrence occurred after excision and local and arterial administration of IL-2. A weekly administration method of docetaxel was therefore selected, resulting in complete remission of the pulmonary metastasis and a partial response of the local recurrence. This favorable clinical outcome in our case suggests that docetaxel therapy may be an option for the treatment of angiosarcoma of the scalp with pulmonary metastasis.

Abstract
Model-based meta-analysis of dose response is a sophisticated method to guide dose and regimen selection. In this report, the effects of paclitaxel dose and regimen (weekly or every 3 weeks) on the efficacy and safety in cancer patients were quantified by model-based meta-analysis of 29 monotherapy trials. Logistic regression models were developed to assess the relationship between dose and objective response rate or neutropenia rate. Survival models were developed to assess the relationship between dose and overall survival or progression-free survival. Paclitaxel efficacy (e.g., objective response rate, median overall survival, and progression-free survival) is correlated with average dose per week (mg/m2/week), whereas safety (e.g., neutropenia rate) is correlated with dose per administration (mg/m2). Weekly paclitaxel regimen at 65–80 mg/m2 is supported to have comparable to better efficacy and lower neutropenia incidence than an every-3-week regimen at 175 mg/m2.

Abstract
As our understanding of cancer pathophysiology has increased, so have the number of targeted therapeutic agents available. By targeting specific molecules involved in tumorigenesis, targeted therapeutic agents offer the potential for significant efficacy against tumor cells while minimizing the adverse effects. We highlight the recently recognized ophthalmic complications of targeted cancer therapy, as well as recently recognized complications of traditional chemotherapeutic agents.

Docetaxel-induced skin toxicities in breast cancer patients subsequent to paclitaxel shortage: a case series and literature review. Support Care Cancer 2013; 21:2679-86. [PMID: 23686402 DOI: 10.1007/s00520-013-1842-3] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/25/2012] [Accepted: 05/07/2013] [Indexed: 10/26/2022]
Abstract
PURPOSE As the result of a recent national shortage in paclitaxel, some patients who were receiving or scheduled to receive weekly paclitaxel were converted to every 3-week (q3w) docetaxel with granulocyte colony-stimulating factor support. Our institution noted higher than expected incidence of severe skin toxicity events attributable to docetaxel during the shortage period among our breast cancer patients. In this report, we summarize the clinical course of the first five cases, review the literature surrounding docetaxel-induced skin toxicity, and offer possible prevention and treatment strategies to improve docetaxel tolerability. METHODS The observation period for this case series was August 1 through October 21, 2011. All patients treated with docetaxel were identified from our electronic medical record. Operable stage I-III breast cancer patients who received ≥ 1 dose of docetaxel monotherapy at 75-100 mg/m(2) q3w were included in this study. The cases of grade 3-4 docetaxel-induced skin toxicities identified by the treating oncologists were then contacted and signed an informed consent through an Institutional Review Board-approved protocol. RESULTS Thirty-four patients met the inclusion criteria. Five patients (14.7 %) experienced grade 3 skin toxicity events attributable to docetaxel, a significantly higher rate than previously reported for docetaxel dosed at 75-100 mg/m(2). CONCLUSIONS Docetaxel-induced dermatologic toxicity is well characterized; nonetheless, its etiology is largely unknown and evidence-based prevention and management strategies are lacking. This report shows that the use of docetaxel 75-100 mg/m(2) q3w subsequent to dose-dense doxorubicin and cyclophosphamide regimen can lead to unacceptable rate of severe skin toxicity.

Abstract
PURPOSE Over the past few years, more and more new selective molecules directed against specific cellular targets have become available for cancer therapy, leading to impressive improvements. In this evolving scenario, a new way of delivering older cytotoxic drugs has also been developing. Many studies demonstrated that several cytotoxic drugs have antiangiogenic properties if administered frequently and at lower doses compared with standard schedules containing maximal tolerated doses (MTD). Such a new strategy, named metronomic chemotherapy, focuses on a different target: the slowly proliferating tumour endothelial cells. About 10 years ago, metronomic chemotherapy was firstly enunciated and hereafter many clinical experiences were published related to almost any cancer disease. This review analyses available studies dealing with metronomic chemotherapy and its combination with several targeted agents in solid tumours. METHODS A computerized literature search of MEDLINE was performed using the following search terms: metronomic OR "continuous low dose" AND chemotherapy AND cancer OR solid tumours. RESULTS Satisfactory results have been achieved in diverse tumour types, such as breast and prostate cancer or paediatric sarcomas. Moreover, many studies have reported that metronomic chemotherapy determined minimal toxicity compared to MTD chemotherapy. Overall, published series on metronomic schedules are very heterogeneous often reporting on retrospective data, while only very few studies were randomized trials. These limitations still prevent to draw definitive conclusions in diverse tumour types. CONCLUSIONS Large well-designed studies are eagerly awaited for confirming the promises of metronomic schedules and their combinations with targeted molecules.

Abstract
OBJECTIVE To evaluate the effectiveness and safety of the mobilization of peripheral blood hematopoietic stem cells by combining docetaxel with granulocyte colony-stimulating factor (G-CSF) in breast cancer patients. METHODS A total of 57 breast cancer patients were treated with docetaxel 120 mg/m(2). When the white blood cell (WBC) count decreased to 1.0×10(9)/L, patients were given G-CSF 5 μg/kg daily by subcutaneous injection until the end of apheresis. Peripheral blood mononuclear cells (MNC) were isolated by Cobe Spectra Apheresis System. The percentage of CD34(+) cell was assayed by flow cytometry. RESULTS At a median 6 of days (range 3-8) after the administration of docetaxel, the median WBC count decreased to 1.08×10(9)/L (range 0.20-2.31). The median duration of G-CSF mobilization was 3 days (range 2-7). The MNC collection was conducted 8-12 days (median 10 days) after docetaxel treatment. The median MNC was 5.35×10(8)/kg (range 0.59-14.07), the median CD34(+) cell count was 2.43×10(6)/kg (range 0.16-16.69). The CD34(+) cell count was higher than 1.00×10(6)/kg in 47 of 57 cases (82.46%) and higher than 2.00×10(6)/kg in 36 cases (63.16%). The CD34(+) cell count was higher than 2.00×10(6)/kg in 27 collections (23.68%). The MNC count and the CD34(+) cell count were correlated with the bottom of WBC after docetaxel chemotherapy (r=0.364, 0.502, P=0.005, 0.000). The CD34(+) cell count was correlated with the MNC count (r=0.597, P=0.000). The mobilization and apheresis were well tolerated in all patients. Mild perioral numbness and numbness of hand or feet were observed in 3 cases. No serious adverse events were reported. CONCLUSION Mobilization of peripheral blood hematopoietic stem cell by combining docetaxel with G-CSF was effective and safety in breast cancer patients.

Abstract
Background The purpose of this study was to evaluate the efficacy and tolerability of weekly docetaxel, cisplatin, and S-1 (weekly TPS) as induction chemotherapy for patients with locally advanced head and neck squamous cell carcinoma (HNSCC). Methods A total of 35 patients with previously untreated, locally advanced HNSCC were enrolled. Seven patients (20%) were diagnosed with stage III HNSCC and 28 patients (80%) were diagnosed with stage IV. Induction treatment included 30 mg/m2 docetaxel on day 1 and 8, 60 mg/m2 cisplatin on day 1, and 70 mg/m2 S-1 on days 1 to 14. The regimen was repeated every 21 days. After three courses of induction chemotherapy, patients received concurrent chemoradiotherapy. Results Among the 35 patients, 30 (85.7%) completed induction chemotherapy. The response to induction chemotherapy was as follows: nine patients (25.7%) achieved a complete response (CR) and the overall response rate (ORR) was 85.7%. Grades 3–4 toxicity during induction therapy included neutropenia (28.5%), neutropenic fever (8.5%), and diarrhea (17.1%). After completion of concurrent chemoradiotherapy, the CR rate was 62.8% and the partial response (PR) was 22.8%. Estimates of progression-free and overall survival at 2 years were 73.2% and 79.3%, respectively. Conclusions Weekly TPS is a promising regimen that is well-tolerated, causes minimal myelosuppression and is effective as an outpatient regimen for locally advanced HNSCC.

Abstract
Taxanes have remained a cornerstone of breast cancer treatment over the past three decades, improving the lives of patients with both early- and late-stage disease. The purpose of this review is to summarize the current role of taxanes, including an albumin-bound formulation that enhances delivery of paclitaxel to tumors, in the management of metastatic breast cancer (MBC). Since the introduction of Cremophor EL-paclitaxel to the clinic in the mid-1990s, a substantial amount of investigation has gone into subjects such as formulation, dose, schedule, and taxane resistance, allowing physicians greater flexibility in treating patients with MBC. This review will also examine how the shrinking pool of taxane-naive patients, a result of the expansion of taxanes into the neoadjuvant and adjuvant settings, will respond to taxane retreatment for metastatic disease. Taxane treatment seems likely to continue to play an important role in the treatment of MBC.

Abstract
PURPOSE Most primary human ovarian tumors and peritoneal implants, as well as tumor vascular endothelial cells, express the CD44 family of cell surface proteoglycans, the natural ligand for which is hyaluronic acid. Metronomic dosing, the frequent administration of chemotherapeutics at substantially lower than maximum tolerated doses (MTD), has been shown to result in reduced normal tissue toxicity and to minimize "off-treatment" exposure resulting in an improved therapeutic ratio. EXPERIMENTAL DESIGN We tested the hypothesis that hyaluronic acid (HA) conjugates of paclitaxel (TXL; HA-TXL) would exert strong antitumor effects with metronomic (MET) dosing and induce antiangiogenic effects superior to those achieved with MTD administration or with free TXL. Female nude mice bearing SKOV3ip1 or HeyA8 ovarian cancer cells were treated intraperitoneally (i.p.) with MET HA-TXL regimens (or MTD administration) to determine therapeutic and biologic effects. RESULTS All MET HA-TXL-treated mice and the MTD group revealed significantly reduced tumor weights and nodules compared with controls (all P values < 0.05) in the chemotherapy-sensitive models. However, the MTD HA-TXL-treated mice showed significant weight loss compared with control mice, whereas body weights were not affected in the metronomic groups in HeyA8-MDR model, reflecting reduced toxicity. In the taxane-resistant HeyA8-MDR model, significant reduction in tumor weight and nodule counts was noted in the metronomic groups whereas the response of the MTD group did not achieve significance. While both MTD and metronomic regimens reduced proliferation (Ki-67) and increased apoptosis (TUNEL, terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling), only metronomic treatment resulted in significant reductions in angiogenesis (CD31, microvessel density). Moreover, metronomic treatment resulted in substantial increases in thrombospondin-1 (Tsp-1), an inhibitor of angiogenesis. CONCLUSIONS This study showed that MET HA-TXL regimens have substantial antitumor activity in ovarian carcinoma, likely via a predominant antiangiogenic mechanism.

Abstract
In patients with metastatic breast cancer, taxane treatment demonstrates activity but is not curative. Targeted treatment modalities are therefore necessary in order to improve outcomes in this group. A randomized placebo-controlled phase II trial was initiated to evaluate effect and toxicity of gefitinib (250 mg QD) and docetaxel 35 mg/m2 (six of seven weeks) (NCT 00319618). The inclusion of 66 patients was planned. The study was closed due to treatment-related toxicity. Of the 18 included patients, seven (of which three received gefitinib) were withdrawn from the study due to toxicity. Of the nine patients receiving gefitinib and chemotherapy, one achieved a partial response and four stable disease. In the chemotherapy of nine patients, four had a partial response and four stable disease. The breast cancer patients in this study were genotyped using a panel of 14 single-nucleotide polymorphisms (SNPs), previously found associated with docetaxel clearance in a cohort of lung cancer patients. We were unable to identify genes related to toxicity in this study. Nevertheless, toxicity was aggravated by the addition of the tyrosine kinase inhibitor. In conclusion, despite adequately tolerated as monotherapy, combination regimens should be carefully considered for overlapping adverse events in order to avoid increased treatment-related toxicity.

Abstract
While metastatic breast cancer (MBC) remains incurable, a vast array of active therapeutic agents has provided the opportunity for long-term disease control while maintaining quality of life and physical function. Optimal management of MBC balances a multitude of factors, including a woman's performance status, social support, symptoms, disease burden, prior therapies, and surrogates for tumor biology. Choosing the most appropriate initial therapy and subsequent sequence of treatments demands flexibility as goals and patient preferences may change. Knowledge of the estrogen receptor (ER), progesterone receptor (PR), and Her2 receptor status of the metastatic tumor has become critical to determining the optimal treatment strategy in the metastatic setting as targeted therapeutic approaches are developed. Patients with ER+ or PR+ breast cancer or both have a wide array of hormonal therapy options that can forestall the use of cytotoxic therapies, although rapidly progressive phenotypes and the emergence of resistance may ultimately lead to the need for chemotherapy in this setting. So-called 'triple-negative' breast cancer - lacking ER, PR, and Her2 overexpression - remains a major challenge. These tumors have an aggressive phenotype, and clear targets for therapy have not yet been established. Chemotherapy remains the mainstay of treatment in this group, but biologically based clinical trials of new agents are critical to developing a more effective set of therapies for this patient population.

Abstract
BACKGROUND The aim of this randomized clinical trial was to evaluate the efficacy and safety of combination (cDC) and sequential (sDC) weekly docetaxel and carboplatin in women with recurrent platinum-sensitive epithelial ovarian cancer (EOC). METHODS Participants were randomized to either weekly docetaxel 30 mg/m(2) on days 1 and 8 and carboplatin area under the curve (AUC) = 6 on day 1, every 3 weeks or docetaxel 30 mg/m(2) on days 1 and 8, every 3 weeks for 6 cycles followed by carboplatin AUC = 6 on day 1, every 3 weeks for 6 cycles or until disease progression. The primary endpoint was measurable progression-free survival (PFS). RESULTS Between January 2004 and March 2007, 150 participants were enrolled. The response rate was 55.4% and 43.2% for those treated with cDC and sDC, respectively. The median PFS was 13.7 months (95% confidence interval [CI], 9.9-16.8) for cDC and 8.4 months (95% CI, 7.1-11.0) for sDC. On the basis of an exploratory analysis, patients treated with sDC were at a 62% increased risk of disease progression compared to those treated with cDC (hazard ratio = 1.62; 95% CI, 1.08-2.45; P = .02). The median overall survival time was similar in both groups (33.2 and 30.1 months, P = .2). The incidence of grade 2 or 3 neurotoxicity and grade 3 or 4 neutropenia was higher with cDC than with sDC (11.7% vs 8.5%; 36.8% vs 11.3%). The sDC group demonstrated significant improvements in the Functional Assessment for Cancer Therapy-Ovarian, Quality of Life Trial Outcome Index scores compared with the combination cohort (P = .013). CONCLUSIONS Both cDC and sDC regimens have activity in recurrent platinum-sensitive EOC with acceptable toxicity profiles. The cDC regimen may provide a PFS advantage over sDC.

Abstract
PURPOSE The purpose of this prospective multicenter phase II study was to evaluate the efficacy and toxicity of weekly docetaxel and fixed dose rate gemcitabine in patients with previously treated advanced soft tissue and bone sarcoma. METHODS Patients with advanced soft tissue or bone sarcoma, previously treated with ifosfamide and anthracycline-based chemotherapies, were treated with docetaxel (35 mg/m(2) over 60 min) and gemcitabine (1,000 mg/m(2) over 100 min) on days 1 and 8 of every 3-week cycle. RESULTS From September 2008 to August 2010, 30 patients were enrolled; 24 (80.0%) were men and median patient age was 45 years (range 17-70 years). The patients received a total of 136 cycles of therapy (median 4 cycles per patient; range 1-15 cycles). Of these 30 patients, none achieved complete response (CR) and 5 achieved a partial response (PR), making the overall response rate 16.7% (95% CI, 2.5-30.8%). Twelve patients had stable disease (SD), resulting in tumor control (CR or PR or SD) in 17 of 30 patients (56.7%). Median progression-free survival was 2.5 months (range 0.8-15.3 months), and median overall survival was 8.4 months (range 1.4-22.3 months). Grade 3 or 4 neutropenia, thrombocytopenia, and anemia were observed in 17 (56.7%), 13 (43.4%), and 4 (13.3%) patients, respectively. None of these patients, however, had febrile neutropenia or bleeding events, and all non-hematologic toxicities were manageable. CONCLUSIONS The combination of weekly docetaxel and fixed dose rate gemcitabine was tolerable and may be an active regimen in patients with previously treated advanced sarcoma.

Abstract
This review concerns the effects on vision and the eye of medications prescribed at three phases of treatment for women with early-stage breast cancer (BC): (1) adjuvant cytotoxic chemotherapy, (2) adjuvant endocrine therapy, and (3) symptomatic relief. The most common side effects of cytotoxic chemotherapy are epiphora and ocular surface irritation, which can be caused by any of several different regimens. Most notably, the taxane docetaxel can lead to epiphora by inducing canalicular stenosis. The selective-estrogen-receptor-modulator (SERM) tamoxifen, long the gold-standard adjuvant-endocrine-therapy for women with hormone-receptor-positive BC, increases the risk of posterior subcapsular cataract. Tamoxifen also affects the optic nerve head more often than previously thought, apparently by causing subclinical swelling within the first 2 years of use for women older than ∼50 years. Tamoxifen retinopathy is rare, but it can cause foveal cystoid spaces that are revealed with spectral-domain optical coherence tomography (OCT) and that may increase the risk for macular holes. Tamoxifen often alters the perceived color of flashed lights detected via short-wavelength-sensitive (SWS) cone response isolated psychophysically; these altered perceptions may reflect a neural-response sluggishness that becomes evident at ∼2 years of use. The aromatase inhibitor (AI) anastrozole affects perception similarly, but in an age-dependent manner suggesting that the change of estrogen activity towards lower levels is more important than the low estrogen activity itself. Based on analysis of OCT retinal thickness data, it is likely that anastrozole increases the tractional force between the vitreous and retina. Consequently, AI users, myopic AI users particularly, might be at increased risk for traction-related vision loss. Because bisphosphonates are sometimes prescribed to redress AI-induced bone loss, clinicians should be aware of their potential to cause scleritis and uveitis occasionally. We conclude by suggesting some avenues for future research into the visual and ocular effects of AIs, particularly as relates to assessment of cognitive function.

Abstract
Breast cancer is the most frequent tumor among women worldwide and is the second cause of cancer-related mortality in the US. Metastatic breast cancer (MBC) accounts for less than 10% of newly diagnosed breast cancer patients and about 30% of early breast cancer patients will develop recurrent, advanced, or metastatic disease. It remains an incurable illness and the primary goal of its management is palliative. Several agents are active for the first-line treatment of MBC. The taxanes, paclitaxel and docetaxel, represent the standard of care for the treatment of these patients. Among the various schedules, docetaxel can be administered weekly, achieving similar efficacy results with lower toxicity compared with conventional schedules. Weekly docetaxel (25–40 mg/m2) has been widely tested in several phase I and II studies both as a single agent and in multichemotherapy regimens, reaching overall response rates ranging from 26% and 86% or 20% and 73% with docetaxel alone or in combination, respectively, depending on doses, associations, and line of treatment. Overall, published data support the administration of weekly docetaxel for the treatment of MBC patients even if data from phase III randomized trials are still lacking.

Abstract
Background Weekly docetaxel has occasionally been used in the neoadjuvant to downstage breast cancer to reduce toxicity and possibly enhance quality of life. However, no studies have compared the standard three weekly regimen to the weekly regimen in terms of quality of life. The primary aim of our study was to compare the effects on QoL of weekly versus 3-weekly sequential neoadjuvant docetaxel. Secondary aims were to determine the clinical and pathological responses, incidence of Breast Conserving Surgery (BCS), Disease Free Survival (DFS) and Overall Survival (OS). Methods Eighty-nine patients receiving four cycles of doxorubicin and cyclophosphamide were randomised to receive twelve cycles of weekly docetaxel (33 mg/m2) or four cycles of 3-weekly docetaxel (100 mg/m2). The Functional Assessment of Cancer Therapy-Breast and psychosocial questionnaires were completed. Results At a median follow-up of 71.5 months, there was no difference in the Trial Outcome Index scores between treatment groups. During weekly docetaxel, patients experienced less constipation, nail problems, neuropathy, tiredness, distress, depressed mood, and unhappiness. There were no differences in overall clinical response (93% vs. 90%), pathological complete response (20% vs. 27%), and breast-conserving surgery (BCS) rates (49% vs. 42%). Disease-free survival and overall survival were similar between treatment groups. Conclusions Weekly docetaxel is well-tolerated and has less distressing side-effects, without compromising therapeutic responses, Breast Conserving Surgery (BCS) or survival outcomes in the neoadjuvant setting.

Bi-weekly docetaxel and gemcitabine regimen in her-2-negative and anthracycline-pretreated metastatic breast cancer patients: a multicenter phase II trial. Cancer Chemother Pharmacol 2011; 68:1009-16. [PMID: 21327683 DOI: 10.1007/s00280-011-1570-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2010] [Accepted: 01/21/2011] [Indexed: 11/28/2022]
Abstract
PURPOSE Bi-weekly gemcitabine (G) in combination with docetaxel (D) is an effective treatment for metastatic breast cancer (MBC) previously treated with adjuvant/neoadjuvant anthracyclines containing regimens with a good toxicity profile. In the present phase II study, we investigated the activity of the same regimen as first-line treatment. METHODS Women with breast cancer pretreated in adjuvant/neoadjuvant setting with anthracyclines received bi-weekly G (1,250 mg/m² days 1, 15) and D (50 mg/m² days 1, 15) every 28 days with restaging after 3 and 6 cycles. RESULTS Overall 42 patients were enrolled. Median age is 48 years (range, 31-71 years). Eight patients (19%) achieved complete responses, 18 (43%) partial responses for an overall response rate (ORR) of 62%; five patients (12%) obtained stable disease (SD), and 8 (19%) patients had progressive disease (PD). After a median 17-month follow-up, the median time to disease progression was 12 months (95% CI, 3-26 months) and the median survival time was 27 months (95% CI, 4-57 months). No grade 4 toxicity was seen except in one patient who developed a grade 4 neutropenia. Grade 3 toxicities were leukopenia (2%), neutropenia (14%), anemia (2%), nausea and vomiting (2%), diarrhea (2%), asthenia (2%), and skin toxicity (12%). CONCLUSION The GD bi-weekly regimen is well tolerated and active as first line in anthracyclines-pretreated women with MBC. It appears as an interesting alternative compared to a 3-week schedule whenever hematological toxicity is the main clinical concern.

Abstract
Background To evaluate whether weekly schedules of docetaxel-based chemotherapy were superior to 3-weekly ones in terms of quality of life in locally advanced or metastatic breast cancer. Methods Patients with locally advanced or metastatic breast cancer, aged ≤ 70 years, performance status 0-2, chemotherapy-naive for metastatic disease, were eligible. They were randomized to weekly or 3-weekly combination of docetaxel and epirubicin, if they were not treated with adjuvant anthracyclines, or docetaxel and capecitabine, if treated with adjuvant anthracyclines. Primary end-point was global quality of life change at 6-weeks, measured by EORTC QLQ-C30. With two-sided alpha 0.05 and 80% power for 35% effect size, 130 patients per arm were needed. Results From February 2004 to March 2008, 139 patients were randomized, 70 to weekly and 69 to 3-weekly arm; 129 and 89 patients filled baseline and 6-week questionnaires, respectively. Global quality of life was better in the 3-weekly arm (p = 0.03); patients treated with weekly schedules presented a significantly worsening in role functioning and financial scores (p = 0.02 and p < 0.001). Neutropenia and stomatitis were worse in the 3-weekly arm, where two toxic deaths were observed. Overall response rate was 39.1% and 33.3% in 3-weekly and weekly arms; hazard ratio of progression was 1.29 (95% CI: 0.84-1.97) and hazard ratio of death was 1.38 (95% CI: 0.82-2.30) in the weekly arm. Conclusions In this trial, the weekly schedules of docetaxel-based chemotherapy appear to be inferior to the 3-weekly one in terms of quality of life in patients with locally advanced or metastatic breast cancer. Trial registration ClinicalTrials.gov NCT00540800.

Abstract
We report eyelid margin changes in 3 patients after docetaxel treatment for breast cancer. These patients were referred to Cincinnati Eye Institute for eyelash abnormalities and/or epiphora and all had been treated with docetaxel in the near past. The ophthalmic complaints started soon after chemotherapy. All 3 cases showed varying degrees of palpebral mucosal inflammation and cicatricial changes leading to marginal entropion. The first patient exhibited very prominent eyelid margin inflammation and diffuse trichiasis without madarosis. The second patient had extensive madarosis and abnormally curved, thin eyelashes with punctal and canalicular obstruction. Her marginal entropion was most prominent at the medial lower eyelids. The last patient showed significant lash misdirection in a scattered distribution and patchy madarosis along with pseudomembranes blocking the puncta. All of these eyelid abnormalities occurred soon after docetaxel treatment for advanced breast cancer. Such changes in the absence of questioning for previous docetaxel use in history taking.

Abstract
PURPOSE P-glycoprotein (Pgp) antagonists have been difficult to develop because of complex pharmacokinetic interactions and a failure to show meaningful results. Here we report the results of a pharmacokinetic and pharmacodynamic trial using a third-generation, potent, noncompetitive inhibitor of Pgp, tariquidar (XR9576), in combination with docetaxel. EXPERIMENTAL DESIGN In the first treatment cycle, the pharmacokinetics of docetaxel (40 mg/m(2)) were evaluated after day 1 and day 8 doses, which were administered with or without tariquidar (150 mg). (99m)Tc-sestamibi scanning and CD56(+) mononuclear cell rhodamine efflux assays were conducted to assess Pgp inhibition. In subsequent cycles, 75 mg/m(2) docetaxel was administered with 150 mg tariquidar every 3 weeks. RESULTS Forty-eight patients were enrolled onto the trial. Nonhematologic grade 3/4 toxicities in 235 cycles were minimal. Tariquidar inhibited Pgp-mediated rhodamine efflux from CD56(+) cells and reduced (99m)Tc-sestamibi clearance from the liver. There was striking variability in basal sestamibi uptake; a 12% to 24% increase in visible lesions was noted in 8 of 10 patients with lung cancer. No significant difference in docetaxel disposition was observed in pairwise comparison with and without tariquidar. Four partial responses (PR) were seen (4/48); 3 in the non-small cell lung cancer (NSCLC) cohort, measuring 40%, 57%, and 67% by RECIST, and 1 PR in a patient with ovarian cancer. CONCLUSIONS Tariquidar is well tolerated, with less observed systemic pharmacokinetic interaction than previous Pgp antagonists. Variable effects of tariquidar on retention of sestamibi in imageable lung cancers suggest that follow-up studies assessing tumor drug uptake in this patient population would be worthwhile.

A literature-based meta-analysis taxane-based doublet versus single-agent taxane chemotherapy in patients with advanced breast cancer. J Cancer Res Clin Oncol 2010; 137:1005-13.

Abstract
PURPOSE Clinical trials have reported conflicting results as to whether taxane-based doublet improves outcome over single-agent taxane in patients with advanced breast cancer. METHODS We performed a meta-analysis comparing primary and secondary end points of taxane-based doublet with single-agent taxane chemotherapy in patients with advanced breast cancer and prior anthracycline treatment. The event-based relative risk ratio (RR) with 95% confidence intervals (95% CI) was derived, and a test of heterogeneity was applied. RESULTS Four eligible trials (2,343 patients) were selected from 488 studies that initially were identified. A significant difference in favoring taxane-based doublet over single-agent taxane was observed in progression-free survival (PFS) (RR, 1.33; 95% CI, 1.02-1.75; P = 0.039) and partial response (PR) (RR, 1.43; 95% CI, 1.10-1.86; P = 0.008). The ORR was higher for patients receiving taxane-based doublet, although not statistically significant (RR, 1.17; 95% CI, 0.91-1.50; P = 0.220). Whereas there was no difference in 1-year survival rate (1-year SR) (RR, 1.05; 95% CI, 0.94-1.17; P = 0.422), clinical benefit (CB) (RR, 1.02; 95% CI, 0.95-1.09; P = 0.642), and complete response (CR) (RR, 0.75; 95% CI, 0.31-1.79; P = 0.512). Toxicities did not differ significantly except stomatitis and diarrhea. CONCLUSION Taxane-based doublet appeared to improve PFS and PR compared with single-agent taxane in the treatment of patients with advanced breast cancer. Further prospective, randomized, controlled trials will be necessary.
