Four patients were prescribed doses 100% above the licensed maximum, all of which involved amisulpride and high-dose quetiapine combinations. The use of high-dose quetiapine is not an isolated finding. Recently the suggestion that high doses of quetiapine is necessary for therapeutic effect has led to prescribers disregarding guidelines, despite the fact that Inhibitors,research,lifescience,medical the only available evidence to support this theory is from case reports [Sparshatt et al. 2008]. Adverse effects were common and occurred equally amongst patients prescribed medication within daily defined limits and those on high-dose combinations.

Both serious adverse events (QTc prolongation and arrhythmia) occurred in high-dose patients, which is not altogether unexpected considering risk of cardiac events is dose related [Taylor et al. 2009]. Extrapyramidal side effects (EPSEs) affected the greatest number of patients in this sample, all of whom were Inhibitors,research,lifescience,medical receiving two atypical antipsychotics or atypical–typical combinations. This finding supports the theory that combining atypical with typical antipsychotics results in loss of atypicality, probably due to additional inhibition of

striatal dopamine receptors [Kapur et al. 2001]. Clinical outcome was variable where documented, with Inhibitors,research,lifescience,medical the majority of benefit being observed for nonpsychotic symptoms. A reduction in psychotic symptoms was documented in a quarter of all patients. Inhibitors,research,lifescience,medical However, differentiating between whether the effect

observed is due to the combination of drugs or the addition of the second drug is a major problem inherent to polypharmacy studies. In this study, the original antipsychotic was gradually removed to observe the effects of the added antipsychotic in two patients only. In both cases, trial discontinuation did result in a significant increase in psychotic symptoms, Inhibitors,research,lifescience,medical suggesting the effectiveness of the polypharmacy regimen as opposed to the added drug only. However, these findings must clearly be interpreted with caution. Documented improvements in adverse effects were uncommon. In a patient with risperidone-induced hyperprolactinaemia and galactorrhoea, the addition of aripiprazole resulted in a reduction in prolactin levels (and associated symptoms) definitely without necessitating a reduction in risperidone dosage. This positive finding has also been reflected in a large RCT [Kane et al. 2009], indicating the potential value of aripiprazole in a subset Entinostat of patients suffering from antipsychotic- induced hyperprolactinaemia. A significant proportion of prescribers considered stopping polypharmacy, possibly reflecting lack of efficacy, tolerability or concerns over long-term safety implications of coprescription. However, the practice continued in the majority of cases, mainly because of patient refusal to medication changes. Some prescribers also expressed fears that reverting to monotherapy would result in relapse and the worsening of psychotic symptoms.

Discussion Overall, results indicate that, compared with noninfected and demographically similar HCV− controls, treatment naïve HCV+ adults present with increased neuropsychiatric symptoms including aspects of depression

(somatic symptoms), anxiety, fatigue, and pain (pain interference). Similar to previous studies, our data (Table 1) indicate that, compared to adults without HCV, adults with HCV have higher plasma www.selleckchem.com/products/Calcitriol-(Rocaltrol).html levels of α-2-macroglobulin (A2Macro; Ho et al. 2010), β-2-microglobulin (B2M; Malaguarnera et al. 2000; ŁApiński et al. 2002), ICAM-1 (El-Gohary et al. 2004; Helaly and Abou Shamaa 2006), IL-8 (Zimmermann et al. 2011; Sousa et al. 2012; Warshow Inhibitors,research,lifescience,medical et al. 2012), Inhibitors,research,lifescience,medical IL-18 (Sharma et al. 2009; Wilkinson et al. 2010; Akcam et al.

2012), MIP-1α (Larrubia et al. 2008; Florholmen et al. 2011), tissue inhibitor of metalloproteinases (TIMP)-1 (Leroy et al. 2004), TNFR2 (Pawlak et al. 2010), vascular cell adhesion molecule-1 (VCAM-1; Bruno et al. 2005; Pawlak et al. 2010), and vWF (Pawlak et al. 2010); these group differences remained significant following a Bonferroni correction for multiple comparisons across an array of 47 immune factors, highlighting the robustness of these findings. Moreover, HCV+ adults are more likely than controls to have an increased inflammatory profile. Within the HCV+ Inhibitors,research,lifescience,medical group, Inhibitors,research,lifescience,medical but not within the HCV− group,

number of inflammatory factors with levels ≥ the LDC significantly correlated with several neuropsychiatric symptoms, showing that an HCV-associated increased inflammatory profile is associated with increased neuropsychiatric symptom severity, specifically aspects of depression (somatic symptoms), anxiety, and pain (pain interference). Results additionally suggest that differences in expression of the network of peripheral immune proteins significantly impact neuropsychiatric function in adults, regardless of HCV status. Neuropsychiatric symptom severity was significantly predicted by specific protein signatures, Inhibitors,research,lifescience,medical consisting of 4–10 plasma immune factors depending on the neuropsychiatric variable, after controlling for HCV status. Each panel of significant immune factors accounted for 19–40% of the variance in depression, anxiety, fatigue, and pain. These analyses reveal potential disease Carfilzomib signatures and individually significant immune factors worthy of further investigation through confirmatory studies (e.g., as treatment targets). A major goal of this study was to identify novel biomarkers that might be relevant to the discovery and development of new treatments for neuropsychiatric symptoms. Five proteins were related to more than one neuropsychiatric variable and are of interest for future study—BDNF, IL-23, RANTES, TNF-α, and TNFR2 (Fig. 1).

Figure 12 Development of squamous cell carcinoma during treatment with vemurafenib (BRAF-inhibitor) These findings highlight how familiarity with the characteristic skin reactions observed in classes or families of targeted chemotherapeutics may help predict what reactions to expect from new agents. Knowledge of the presentation and treatment of the cutaneous toxicities caused by targeted

therapies approved for the treatment of colorectal cancers is extremely important for the practicing oncologist and dermatologist. Inhibitors,research,lifescience,medical Successful treatment improves patients’ quality of life while undergoing these therapies. It addition, by minimizing the cutaneous side effects patients experience these life-saving treatments can be continued at the proper doses and durations to allow for the most effective treatment of their cancers.

Before surgical advances allowed safe resection of colorectal liver metastases (CRLM), patients Inhibitors,research,lifescience,medical were treated primarily with systemic therapies. In fact, over two decades have passed since bolus 5-fluorouracil (5-FU) was the standard of care for patients with mCRC (8-10). Variations in the administration of 5-FU and combinations with agents to modulate its activity Inhibitors,research,lifescience,medical [levamisole and leucovorin (LV)] produced incremental improvements in patient outcomes; however, median overall survival (OS) largely remained near 12 months (11-14). A major

advance in systemic therapies for mCRC was reported in 2000 when two phase III trials showed that the addition of irinotecan (CPT-11), a DNA topoisomerase I inhibitor, to 5-FU/LV significantly increased overall response rates (ORR), progression-free survival (PFS), and OS (15-17). In the report by Saltz et al., weekly treatment consisted of irinotecan (125 mg/m2), bolus 5-FU (500 mg/m2), and LV (20 mg/m2) (IFL) (15). In the 2nd trial, Douillard et al., observed improved outcomes Inhibitors,research,lifescience,medical using GSK-3 bi-weekly FOLFIRI (irinotecan, 180 mg/m2; LV, 200 mg/m2; and bolus 5-FU, 400 mg/m2 followed by 22 h infusional 5-FU, 600 mg/m2) (16). These positive studies led to the acceptance of the combination of irinotecan with 5-FU/LV for first-line therapy of mCRC. During the same period of time that improvements with irinotecan were observed, oxaliplatin, a platinum-based agent that blocks DNA replication, was also tested in combination with 5-FU/LV (FOLFOX) for patients with mCRC (18). In a phase III study reported by de Gramont et al., patients who were administered FOLFOX4 (LV, 200 mg/m2; 5-FU, 400 mg/m2 bolus followed by 22 h infusion of 600 mg/m2; and oxaliplatin, 85 mg/m2) had improved ORR and prolonged PFS, although increases in OS did not reach statistical significance (19).

They are also a cause of patients

leaving the ED before being seen by a clinician [7-9], adverse events [10], restricted access to emergency care [11] and increased mortality rates [12]. To address these chronic problems in EDs, wait molecular weight calculator targets have been applied as a means to monitor, assess and, Inhibitors,research,lifescience,medical therefore, improve the overall experience and quality of care. The focus on targets has triggered controversy about their effectiveness [13-20]. Findings from a recent systematic review [21], suggest that the 4 hour ED wait target in the English NHS has failed to consistently improve clinical outcomes and cautions countries which have embarked upon similar schemes [22,23] to learn these Inhibitors,research,lifescience,medical lessons. Certainly, these targets can speed up the patients’ journey through the ED [24,25], selleck chem Ruxolitinib particularly as they concentrate organisational and clinical efforts in meeting them [26-30]. However, qualitative studies, focusing Inhibitors,research,lifescience,medical on clinicians’ understanding of the target’s impact suggest that although patient flow and ED experience for staff and patients may have been improved, this has happened at the expense of quality time for communication and treatment [31]. This paper aims to fulfil a gap in the literature

Inhibitors,research,lifescience,medical by examining changes in clinical and organisational processes that preceded or followed the introduction of an ED wait target. Its main

objective is to demonstrate the role of space, time and information technology in the optimisation of patient flows. It Inhibitors,research,lifescience,medical does this by examining how these social and technical elements were used to support the 4 hour wait time target in the English NHS and what it means for clinicians to practice emergency care in this environment. Study context The (arbitrary [31]) 4 hour wait target was announced by the English Department of Health in 2000 [32,33], and took effect in January 2005. Without any reference Carfilzomib to other equally important sources of ED overcrowding, such as resources, staffing and bed availability [34,35], the idea was that through this target, EDs would be forced to adopt private sector styles of management [36-38] so as to optimise their operations [39], particularly in an NHS of increasing number of ED attendees (from 13.9 m in 1988 to 21.3 m in 2011) and of fewer hospital EDs (from 310 in 1988 to 150 in 2009). Politically, the context for this policy direction was one of the perennial “crises” in the NHS, with extensive media coverage [40] of patients waiting for long periods of time on trolleys in EDs.

Here again, the quality of foreign subjects in Japan may be questioned, and several ways to assess ethnicity have been designed, to the satisfaction of Japan’s regulatory authority. The data generated this way have been judged acceptable by the MHLW. ICH E5 defines two types of ethnic factors that may have an influence on drug development, Intrinsic factors are genetic and Inhibitors,research,lifescience,medical related to the actual human population of the regulatory area. Extrinsic factors arc related to the culture of the area. Early after the publication

of the guideline in Japan, attention was focused on intrinsic ethnic factors, Verdinexor (KPT-335)? especially genetic differences in drug metabolism. It is true that the frequencies of various types of metabolizers for mephenytoin or cytochromes is notably different, according to the country considered. However, this Inhibitors,research,lifescience,medical is no longer considered a major

problem in bridging strategies. The future of drug development The regulatory authorities of Japan have consistently expressed the view that major bridging issues lie rather on the side of extrinsic factors, such as differences in disease definitions, modalities of treatment, application of GCP regulations, and the design of clinical trials, especially for the selection of end points. It Inhibitors,research,lifescience,medical has also been clear that the bridging process is a temporary one. It actually constituted a threat, to Japanese clinical and medical research, with fewer and fewer clinical trials being conducted in Japan. With the help of CROs and SMOs, this trend is already changing, and the numbers of consultations with the DO are rapidly increasing, for

bridging strategies as well as traditional and global drug development, For companies, it is easier to market, a new drug in a country where it has been Inhibitors,research,lifescience,medical tested and where opinion leaders are familiar with it. The incentives for physicians in clinical research are increased by the possibility of publishing interesting data. The future of drug development, lies therefore in its globalization. Large pharmaceutical corporations have started to Inhibitors,research,lifescience,medical conduct multinational phase 3 trials involving Western and Japanese sites, leading to global simultaneous submission to the main regulatory authorities of the World. This will be facilitated by the adoption of a common technical document (CTD) framework for electronic submissions. Global submission and approval will bring the products to the main pharmaceutical markets quicker, to the benefit, of the industry and patients. Anacetrapib These strategies must be taken into account as early as possible in the drug development process. The participation of except international CROs is needed to help pharmaceutical companies implement these strategics. In the particular case of Japan, knowledge of international and national regulations is not enough. Companies need to have a good understanding of cultural differences to negotiate their drug development programs with the authorities.

In addition to the full-factorial model, we conducted a conjunction analysis across both linguistic tasks to examine whether both tasks

recruit overlapping brain areas. For the analysis of fMRI data, the resulting statistical DAPT Inhibitor parameter maps were thresholded at P < 0.001 uncorrected. All brain areas surviving this threshold are reported in the results section. Inhibitors,research,lifescience,medical However, we restrict the discussion of data to effects found in a priori regions of interest (ROI) such as inferior and middle frontal regions, inferior parietal, middle, superior, and inferior temporal regions including the fusiform gyrus. We report the significance level at the peak level and at the cluster level corrected for multiple comparisons (family-wise error [FWE] corrected P-values). Only clusters of at least 25 connected

voxels (i.e., 675 mm3) Inhibitors,research,lifescience,medical are reported. Given the a priori hypothesis of linguistic task effects in the LIFG, we also ran ROI analyses using small but volume correction (SVC) implemented in SPM8. It is recommended to derive the location for the ROI from meta-analyses of functional imaging studies that explored the process of interest like “semantic processing” (Poldrack 2007; Poldrack et al. 2011). ROI analyses Inhibitors,research,lifescience,medical were performed with 15 mm spheres around the peak voxel (a) in the LIFG (MNI coordinates: x = −44, y = 24, z = 4, see Fig. S1 for location) showing activation for “semantic processing” in a meta-analysis provided by the Neurosynth database (source: http://neurosynth.org/terms/semantic-processing; number of implemented studies: 60), and (b) in the LIFG (MNI coordinates: x = −36, y = 33, z = −12) showing linguistic task effects in the Wright et

al. (2011) study. Although statistical effects drawn from ROI analyses Inhibitors,research,lifescience,medical should be corrected for multiple comparisons (cf., Poldrack 2007), we used liberal significance thresholds of P < 0.005 (uncorrected) with at least five connected voxels to avoid Type-II errors (cf., Lieberman and Cunningham Inhibitors,research,lifescience,medical 2009). For labeling of brain regions, we transformed MNI-coordinates to the Talairach space and used the “Talairach Daemon Client” (Lancaster et al. 1997, 2000). All coordinates were reported in MNI space in the results section. Results Experiment 1 Behavioral data obtained Anacetrapib in the MRI scanner Reaction times The mean RTs averaged across participants and items and the standard errors of the mean (SEM) are displayed in Table ​Table2.2. We subjected the correct RTs to an omnibus test consisting of a two-way analysis of variance (ANOVA) by participants (F1) and by items (F2) in which Relatedness (2 levels: related, unrelated) was considered as a within-subjects factor and in which List (4 levels: list 1, list 2, list 3, list 4) was considered as between-subject factor. The factor List was introduced merely to extract any variance due to the counterbalancing of critical items.

During this timeframe in Maryland, 4064 men underwent either RP or RALP. About 77% of the cases were handled by high-volume surgeons. When surgery was performed by a low-volume surgeon, the case was more likely to be robotic, and the patients were more likely to be of non-white ethnicity, have a longer LOS, and be

more likely to be readmitted and/or need an ICU stay. The analysis likewise showed that high-volume surgeons had patients with a lower LOS, readmissions, and need for ICU. Once again, surgical experience is demonstrated Inhibitors,research,lifescience,medical to markedly affect outcomes for prostate surgery. Wong and colleagues,5 from Melbourne, presented an excellent paper outlining an international multicenter study examining the various selleck chem criteria used to select Inhibitors,research,lifescience,medical men for AS among men who elected to undergo RP. This group compared the “Klotz criteria” and the “Van den Berg Prostate Cancer Research International Active Surveillance (PRIAS) criteria” among a group of

800 men treated with RP from three centers in the United Kingdom, Canada, and Australia. They were specifically looking for upstaging (≥ 7 Gleason score) and upstaging Inhibitors,research,lifescience,medical (≥ pT3 disease). All 800 met the Klotz criteria and 410 met the PRIAS criteria as well. Klotz and PRIAS upgrading and upstaging was 51%, 43%, and 18%, 12%, respectively. They also reported that the predictors within criteria boundaries of finding high-risk disease at surgery were age, palpable disease, and more positive cores. The most interesting finding of this paper was that more men from Australia were reclassified (upstage Inhibitors,research,lifescience,medical or upgrade), 43% to 51%, when compared with Europe and North American sites, 23% to 25%, owing to, per the authors, more stringent selection criteria, thus less reclassification. These and other data presented all point to the need for an internationally agreed-upon

set of selection criteria for AS. Kim and associates,6 from New York, Inhibitors,research,lifescience,medical presented a paper analyzing the trends in use of incontinence procedures after RP. Among the procedures studied were bulking agents, urethral slings, and artificial urinary sphincters (AUS). This group used the Surveillance Epidemiology and End Results cancer registry linked to Medicare claims data to identify men > age 65 years who underwent open or minimally invasive (MIS) prostatectomy between 2000 and 2007. Overall, data from 16,348 men were included (3523 were MIS). Approximately 6% of the men received a Dacomitinib procedure (no difference between open and MIS). Risk increased with age, location (South), race (white), and comorbid state. Risk was lower for non-metropolitan residence. Fifteen percent had more than one procedure; 39%, 13%, and 34% received bulking agents, slings, and AUS, respectively. The median time from prostatectomy varied with year of surgery, between 16 and 29 months. It is quite interesting that, in many studies, incontinence is reported at levels between 15% and 70%, yet only 6% of men seem to be receiving selleck catalog treatment for this.

Specifically, we examined whether higher fitness levels would be associated with greater concentrations of N-acetylaspartate (NAA). NAA is a nervous system specific metabolite (Nadler and Cooper 1972) found predominantly

in cell bodies of neurons (Moffett et al. 1991). We reasoned that if aerobic fitness was predominantly influencing cerebral vasculature, NAA levels should not vary as a function of aerobic fitness. However, if aerobic fitness influences the number or viability of neurons, in addition to possibly influencing vasculature, then higher aerobic fitness levels Inhibitors,research,lifescience,medical should be associated with greater concentrations of NAA or offset any age-related reduction in NAA. Such a finding would support the argument that aerobic fitness influences neuronal viability in aged humans and provides additional insight about the mechanisms by which fitness enhances cognition. Methods Participants

One hundred Inhibitors,research,lifescience,medical thirty-seven community-dwelling participants (90 females; 47 males) between the ages of 58 and 80 years (mean age = 66.08; SD = 5.50 see Table 1) were recruited from Champaign-Urbana and east-central Illinois to participate in a randomized exercise intervention trial spanning one year. The results described in this study are limited to the baseline assessment of cardiorespiratory fitness and NAA. All participants were screened for cognitive impairment Inhibitors,research,lifescience,medical using the modified Mini-Mental Status Examination (Stern et al. 1987) and were excluded if the minimum score of 51 was not obtained (maximum score of 57). Additional inclusion criteria consisted of having normal or corrected to

normal vision, absence of clinical depression as measured by the five-item Inhibitors,research,lifescience,medical Geriatric Depression Scale (>3; Sheikh and Yesavage 1986), and not very physically active as defined by sellectchem participation in physical activity on two or fewer days of the week in the Inhibitors,research,lifescience,medical past six months. All participants met or surpassed www.selleckchem.com/products/Bortezomib.html safety criteria for participating in an MR study, including no history of head trauma, head or neck surgery, diabetes, neuropsychiatric or neurological conditions including brain tumors, or having any ferrous metallic implants that could cause injury due to the magnetic field. Individuals reporting the use of psychiatric or neurological medications were excluded from participation in the study. Finally, all participants provided physician’s AV-951 consent to engage in fitness testing and signed an informed consent approved by the University of Illinois. Table 1 Participant characteristics. Aerobic fitness assessment Aerobic fitness (VO2 peak) was assessed by graded maximal exercise testing on a motor-driven treadmill. The participant walked at a speed slightly faster than their normal walking pace (1.5–4.3 miles per hour), with increasing grade increments of 2% every other minute.

Patients with Erlotinib discrete suspicious-appearing lesions were eligible for inclusion in this study. Suspicious lesionsincluded: leukoplakia, erythroplakia, ulceration, a cauliflower appearance, and a lesion on an immobile vocal cord, thus excluding patients with benign-appearing lesions, such as polyps, nodules, Reinke’s space edema, and findings compatible with chronic laryngitis due to reflux. Patients with suspicious lesions were referred Inhibitors,research,lifescience,medical for TFL biopsy in order to determine whether the lesion was malignant or benign. The pathologic diagnosis of invasive carcinoma from a TFL biopsy was considered equivalent to the pathology results from a direct laryngoscopy

biopsy. All patients with benign pathology Inhibitors,research,lifescience,medical or carcinoma in situ (CIS), however, were referred to subsequent direct laryngoscopy for definitive diagnosis. CIS results were added to invasive carcinoma results when sensitivity and specificity measurements were calculated. Pathological

results of the specimens from both procedures were compared. All relevant demographic and clinical data Inhibitors,research,lifescience,medical were retrieved for analysis. The study was approved by the institutional ethics committee, and all suitable patients signed an informed consent form prior to undergoing the procedure. Biopsy Technique We use a Pentax-FNL-10 RP3 (Montvale, NJ, USA) and ENT 2000-vision sciences (Orangeburg, NY, USA) for performing flexible TFL. The endoscope is connected proximally to a camera and Inhibitors,research,lifescience,medical monitor. The soft palate is locally anesthetized with 10% xylocaine spray, and the nasal cavity is anesthetized with 2% tetracaine mixed with 0.05% oxymetazoline HCl. The endoscope is covered with a disposable plastic sheath that has a working channel (ENT slide-on Endo-sheath system, Medtronic, Minneapolis, MN, USA). A 2-mm diameter biopsy forceps is inserted through the working channel (Laryngeal Biopsy Forceps, Medtronic, Minneapolis, MN, USA). After insertion of the endoscope, 2 mL of 2% lidocaine is injected through

the working channel. In some cases Inhibitors,research,lifescience,medical more than one biopsy specimen was collected in order to sample different parts of the lesion. The tissue was collected in a designated pathology plastic cup containing 0.9% NaCl solution. The patients remained for AV-951 observation in the clinic for 30 minutes after undergoing the procedure. RESULTS A total of 117 patients that underwent in-office biopsies for suspicious-appearing lesions in the larynx participated in the study. The group included 94 males and 23 females with a Sorafenib B-Raf median age of 66 years (range 30–89 years). The most common presenting symptom was dysphonia (66.6%, n= 78). Other symptoms included dysphagia, chronic cough, throat discomfort, and dyspnea. Sixty-six patients (56.4%) had additional co-morbidities, including ischemic heart disease, chronic renal failure, chronic lung disease, and a history of prior cerebrovascular accident; 71 patients (60.6%) were smokers.

Based on the previous evidences regarding the role of anthracyclines and the modified toxicity profile of PLD, this agent has been a rational choice for further evaluation as a single-agent and in CGP057148B combination with platinum agents in the treatment of ovarian cancer. 3. Pegylated Liposomal

Doxorubicin: Activity in Ovarian Cancer 3.1. Phase II Studies with PLD as a Single-Agent or in Combination The initial studies evaluating PLD have been conducted in recurrent ovarian cancer, as a single-agent monotherapy or in combination with platinum (carboplatin) and later on with trabectedin or other new drugs. A summary of phase II studies using Inhibitors,research,lifescience,medical PLD as a single agent or in combination regimens in ovarian cancer is presented in Table 1 [26–35]. Table 1 Phase-II studies with pegylated liposomal doxorubicin (PLD) as a single agent or in combination regimens. Nonrandomized Inhibitors,research,lifescience,medical phase II trials of PLD in platinum-resistant ovarian cancer patients documented the biological activity of this agent

in this clinical setting, with than objective response rates of approximately 10–20% being reported in several trials [18, 25, Inhibitors,research,lifescience,medical 31]. Data indicated that palmar-plantar erythrodysesthesia (PPE; hand-foot syndrome, toxic acral erythema) and mucositis were the most common toxicities of PLD, reported in up to 50% of treated patients. PPE usually occurs Inhibitors,research,lifescience,medical after two or more courses of treatment and the risk of incidence increases with multiple repeated treatments. PPE is related to dose intensity and dose interval rather than to peak dose level. Although not life threatening, PPE can negatively impact the quality of life, and it is a major cause of both dose reduction and treatment discontinuation [61, 62]. As regards

the cardiac toxicity, in several trials PLD formulation has been related to a better safety profile compared to conventional doxorubicin [63]. Compared to the 7.5% incidence of irreversible cardiotoxicity Inhibitors,research,lifescience,medical at cumulative doses of 400–550mg/m2 reported with doxorubicin [64], most of the studies of PLD showed a lower incidence AV-951 of cardiac failure even at doses higher than 500mg/m2 [65, 66]. In a prospective trial performed on patients with advanced gynecological malignancies treated with PLD, the cardiac safety was further assessed at histology (endomyocardial biopsies), showing no myocardial damage in patients treated with PLD (median PLD dose of 708mg/m2) [67]. Thus, the optimal cardiac safety profile of PLD may allow a prolonged treatment; encouraging results from a phase II trial in AIDS-related Kaposi’s sarcoma patients treated with PLD up to a 2360mg/m2 cumulative dose have been reported [68]. In metastatic breast cancer patients also doses greater than 450mg/m2 were not associated with a significant decrease in LVEF from baseline compared to conventional doxorubicin [69].
