    ABSTRACT: Daucus carota (DC) is a herb used in folklore medicine in Lebanon to treat numerous diseases including cancer. Recent studies in our laboratory on DC oil and its fractions revealed potent anticancer activities in vitro and in vivo. The present study aims to investigate the effect of the most potent DC fraction, pentane/diethyl ether (50:50), on lung, skin, breast and glioblastoma cancer cell motility and invasion. Upon treatment, a pronounced decrease in cancer cell motility was observed in the 4 cell lines. The treatment also led to a decrease in cancer cell invasion and an increased cell adhesion. Additionally, the DC fraction caused a decrease in the activation of the ρ-GTPases Rac and CDC42, a finding that may partially explain the treatment-induced decrease in cell motility. The current study demonstrates a crucial effect of the DC pentane/diethyl ether fraction on cancer cell motility and metastasis, making it a potential candidate for cancer therapy specifically targeting cancer motility and metastasis. © 2015 S.

    ABSTRACT: We report the case of an 80-year-old patient who presented with a progressive prostate metastatic cancer with poor performance status. The patient had already benefitted from docetaxel and abiraterone. A new line of chemotherapy by cabazitaxel was started with good response, and there was a dramatic improvement in general status and pain symptoms. Age and performance status alone should not be limiting decision factors for elderly cancer patients. © 2015 S. Karger AG, Basel.

    ABSTRACT: Bevacizumab is a recombinant humanized monoclonal antibody that obstructs the vascular endothelial growth factor (VEGF) pathway. Despite its extensive employment in the treatment of primary tumors of the brain, experience of brain metastatic disease, a frequent complication in patients with lung cancer, is very limited. On the basis of the strong antiedemigenous effect and no risk of intracranial bleeding, we administered a bevacizumab-based chemotherapy to patients with non-small-cell lung cancer (NSCLC) and symptomatic metastatic brain lesions who were not suitable candidates for a specific local therapy. The patients received bevacizumab 7.5 mg/kg and cisplatin 75 mg/m(2) on day 1, and gemcitabine 1,250 mg/m(2) on days 1 and 8, every 21 days. We studied 13 patients with clinical and radiological progressive brain metastases; the majority had a treatment-naïve disease. Bevacizumab-based chemotherapy was found to be well tolerated and effective: progression-free survival (PFS) was 9.1 months (range: 0.9-39.2+) and overall survival (OS) was 9.6 months (range 3-41.5+). Bevacizumab-based therapy proved to be feasible and safe. The PFS and the OS data are very encouraging as well as the symptomatic benefit due to bevacizumab's high capacity to provide a long-lasting decrease of perilesional edema. © 2015 S.

    ABSTRACT: We evaluated whether the concurrent β-blocker use in early breast cancer patients influenced the outcome in terms of preventing tumor recurrence after adjuvant chemotherapy. We retrospectively reviewed the medical records of 610 patients with breast cancer. Thereafter, we compared overall disease-free survival (DFS) between β-blocker users and nonusers. Those not receiving β-blockers had a relatively longer mean DFS (10.8 vs. 9.7 years), although the difference did not reach statistical significance (p = 0.651). When the survival analysis was adjusted for age, tumor stage, hormone receptor status and HER2 status, the results remained unaltered, suggesting that β-blocker use did not significantly improve overall DFS (HR, 0.849; 95% CI, 0.537-1.343; p = 0.485). Our findings failed to confirm previous results indicating a potential antitumor effect of β-blockers. © 2015 S. Karger AG, Basel.

    ABSTRACT: Pharmacogenetic studies on irinotecan treatment in patients with metastatic colorectal cancer have indicated that genetic polymorphisms in UGT1A1*6 can lead to decreased enzyme activity and accumulation of the toxic metabolite SN-38. Here, we compared the prevalence of UGT1A1*6 in an Iranian population of different ethnicities with those of other populations. A total of 300 healthy people of different ethnic groups including Persian, Azari, Lure, Kurdish, Arab, Baluch and Caspian in the Iranian population were enrolled. Genotyping of the UGT1A1*6 alleles (G/G, A/G, A/A) was performed by polymerase chain reaction-restriction fragment length polymorphism and direct genomic DNA sequencing. The most predictive genotype among the Iranian ethnic groups, especially Persian, was the G/G genotype (wild-type genotype). The frequency of the A/G genotype among the Persian, Azari, Lure, Kurdish, Arab, Baluch and Caspian ethnicities were 15.69% (n = 27), 11.11% (n = 8), 5.88% (n = 1), 9.09% (n = 1), 10% (n = 1), 20% (n = 1) and 0% (n = 0), respectively. Only one person with Persian ethnicity was homozygous for the mutation in UGT1A1*6 (0.58%). Additionally, the frequency of the A and G alleles in Iranians was 6.83 and 93.16%, respectively. The identification of the UGT1A1*6 alleles is necessary among the different Iranian ethnic groups before irinotecan therapy, suggesting that genotyping would be helpful for clinicians to optimize chemotherapy or identify individuals at risk of adverse drug reactions before clinical trials. © 2015 S.

    ABSTRACT: The efficacy and tolerance of a gemcitabine and vinorelbine (GV) combination as salvage therapy have not been reported in elderly patients with advanced non-small cell lung cancer (NSCLC). We reviewed elderly patients with advanced NSCLC who had disease progression after one or more chemotherapy regimens, at least one including platinum, and then who were treated with GV as the salvage therapy. In total 40 patients were analyzed. GV was at least the third-line chemotherapy in 24 patients (60.0%). Only 2 patients (5.0%) experienced grade 3 febrile neutropenia. Nonhematologic toxicities were generally mild and there was no treatment-related mortality. Among 29 patients evaluable for treatment response, 10 (34.5%) and 9 (31.0%) achieved a partial response and stable disease, respectively. The median overall survival was 10.3 months and the median progression-free survival was 3.1 months. GV in combination is an effective and tolerable salvage regimen in elderly and heavily pretreated patients with advanced NSCLC. © 2015 S. Karger AG, Basel.

    ABSTRACT: Multidrug resistance (MDR) is a major problem in cancer treatment. Cu complexes possess the ability to overcome MDR in cancer. Therefore, the search for new Cu complexes is of great clinical significance and we address the anticancer effects of a previously synthesized novel 9-phenyldibenzo[a,c]phenazin-9-ium cation [1(+)] as [1] [CuCl2] and as [1] [I]. The existence of the monovalent Cu(I) in [1] [CuCl2] was proven by electron paramagnetic resonance (EPR) studies and in vivo anticancer effects were studied in animals. The monovalent nature of the Cu ion in [1] [CuCl2] was determined through EPR. The mean survival time of mice bearing doxorubicin-resistant Ehrlich ascites carcinoma cells is longer when [1] [I] is injected intraperitoneally whereas [1] [CuCl2] does not significantly increase the median survival in tumor-bearing mice. Compounds do not follow the immunomodulatory route and only [1] [I] shows cytotoxic activity in both MDR and drug-sensitive leukemia cell lines. An organic iodide complex rather than a cupric complex possesses direct cytotoxic potential. © 2015 S. Karger AG, Basel.

    ABSTRACT: Teicoplanin (TEIC) is a glycopeptide currently used for the treatment of methicillin-resistant Staphylococcus aureus (MRSA). A plasma trough concentration (Cmin) of >20 mg/l should be used for severe infections. The aim of this study was to assess the efficacy, safety and use of Cmin >20 mg/l on day 4-6 in patients with complicated MRSA infections. Blood samples were drawn from the 41 included patients just before TEIC administration between day 4 and 6. The patients were divided into three groups (group A: >20 mg/l, group B: 10-20 mg/l and group C: <10 mg/l) based on their Cmin on day 4-6. Differences in efficacy between the groups were significant, but differences in safety were not. The patients in group A required lower cumulative doses than those in either groups B or C. The optimal clinical efficacy and safety might be associated with TEIC Cmin on the fourth to sixth day. © 2015 S. Karger AG, Basel.

    ABSTRACT: Acinetobacter spp. is an opportunistic pathogen that has demonstrated increasing relevance in nosocomial infections. Carbapenem-resistant strains have been reported worldwide. Since 2014, screening for metallo-β-lactamases (MBLs) in all Acinetobacter spp. isolates using phenotypic methods and PCR has been implemented at the University Hospital Center Zagreb. The bacterial strain was isolated from the drain of a child hospitalized in a paediatric intensive care unit and identified as Acinetobacter guillouiae using a MALDI TOF automated system. The strain was resistant to meropenem, ceftazidime, cefotaxime, ceftriaxone, cefepime, sulbactam/ampicillin, gentamicin and ciprofloxacin, intermediately susceptible to piperacillin/tazobactam and imipenem, and susceptible to amikacin and colistin. The Hodge test and combined disk test with EDTA were positive. The MICs of meropenem and imipenem were not reduced by cloxacillin, but a small reduction of two dilutions was observed following the addition of sodium chloride, which indicated that OXA-58 was produced. PCR and sequencing of chromosomal DNA from boiled colonies revealed blaOXA-58 and blaNDM-1 genes. This is the first report of NDM-1 in Acinetobacter spp. in Croatia. The early detection of these genes will aid in the prevention and in the achievement of adequate infection control by limiting the spread of these organisms. © 2015 S. Karger AG, Basel.

    ABSTRACT: We compared the prevalence of extended-spectrum beta-lactamase (ESBL) producers in the faecal samples of 1,109 healthy individuals screened for employment purposes and in 531 asymptomatic individuals applying for long-term care (LTC). Eosin-methylene blue agar plates supplemented with 2 mg/l cefotaxime were used to determine which individuals were ESBL producers. ESBL phenotype was confirmed by double-disk synergy test and ESBL genes were identified by sequencing. ESBL producers were characterized by co-resistance and integron carriage. ESBL producers were more frequent in the LTC applicants than in the employment screening individuals (7.2 vs. 2.0%; p < 0.0001), with 43 Escherichia coli, 18 Klebsiella pneumoniae, 1 Klebsiella oxytoca and 1 Proteus mirabilis being found. In the employment screening individuals, only E. coli was found. Most ESBL genes (79.4%, 50/63) were blaCTX-M type; blaCTX-M-15 was more frequent in the LTC applicants (p < 0.001). Regarding ESBL genes and integron diversity, E. coli isolates from the LTC applicants were more similar to K. pneumoniae than to E. coli from the employment screening individuals. These differences in the characteristics of ESBL producers may represent different sources of colonization. Most LTC applicants harboured K. pneumoniae or E. coli that were probably hospital-acquired whereas the E. coli isolates of many healthy individuals showed similarities to environmental E. coli. © 2015 S.

    ABSTRACT: Surgical excision constitutes an important part of the treatment of local advanced malignant melanoma. Due to the high recurrence risk, adjuvant high-dose interferon therapy is still the only therapy used in stage IIB and III high-risk melanoma patients. One hundred two high-risk malignant melanoma patients who received high-dose interferon-α-2b therapy were evaluated retrospectively. The clinicopathological features, survival times, and prognostic factors of the patients were determined. The median disease-free and overall survival times were 25.2 and 60.8 months, respectively. Our findings revealed that male gender, advanced disease stage, lymph node involvement, lymphatic invasion, the presence of ulceration, and a high Clark level were significant negative prognostic factors. In light of the favorable survival results obtained in this study, high-dose interferon treatment as adjuvant therapy for high-risk melanoma is still an efficient treatment and its possible side effects can be prevented by taking the necessary precautions. © 2015 S.

    ABSTRACT: At diagnosis, about 35% of patients with gastric cancer present with distant metastases, and most patients with gastric cancer and liver metastases are excluded from curative surgery. We report a case of human epidermal growth factor receptor-2 (HER2)-negative gastric cancer with metastases to the liver and perigastric lymph nodes. The patient (a 60-year-old man) was considered unresectable at diagnosis and was treated with palliative chemotherapy (docetaxel plus cisplatin and 5-fluorouracil by continuous intravenous infusion over 5 days every 3 weeks). However, after 6 courses of chemotherapy, a computed tomography scan showed a reduction of the liver metastasis and the disappearance of the enlarged perigastric lymph nodes. The patient then underwent a curative gastrectomy, lymphadenectomy and liver resection. After surgery, the patient was treated with 6 courses of FOLFOX-4 regimen as adjuvant chemotherapy. With a follow-up of 26 months after surgery, the patient is alive and disease free. In patients with metastatic gastric cancer, the prognosis is poor with a median overall survival of 11 months since curative treatments are excluded; however, this case illustrated that a personalized treatment with chemotherapy and surgery can allow a curative strategy in selected patients with HER2-negative advanced gastric cancer. © 2015 S.

    ABSTRACT: Multiple induction regimens have been developed for adult patients with acute lymphoblastic leukemia (ALL). However, there have been no prospective randomized trials that directly compare these regimens. In this study, we wanted to evaluate the outcome of 50 adult ALL patients treated with BFM (i.e. Berlin-Frankfurt-Munster, n = 20) and hyper-CVAD (n = 30) protocols between March 2006 and October 2012. The median age was 25 years in the BFM group and 30.5 years in the hyper-CVAD group with a male/female ratio of 15:5 and 17:13, respectively. Forty-five percent of the patients in the BFM group and 30.3% in the hyper-CVAD group were <25 years old. The majority of cases were B cell in origin (80% in the BFM group and 70% in the hyper-CVAD group). Complete remission after induction therapy was achieved in 95 and 96% of the patients, respectively. The median follow-up time was 37 months. The 5-year survival rate was higher in the BFM group than in the hyper-CVAD group (59 vs. 34%). There were also no complications which could cause a delay during the hyper-CVAD regimen. Both chemotherapies were well tolerated. None of the patients died from drug-related toxicity. Only mild liver enzyme elevations were seen as toxicity in the BFM group; these did not cause any delay in therapy. The BFM regimen seems to be feasible for adult patients with ALL in terms of tolerability and efficacy, especially in young adults. © 2015 S. Karger AG, Basel.

    ABSTRACT: Otitis media (OM) is one of the most common infections in children, Streptococcus pneumoniae and nontypable Haemophilus influenzae being the two most common pathogens isolated in the middle ear fluid (MEF) of children with OM. Cefditoren is a third-generation cephalosporin with broad-spectrum antibacterial activity, including activity against those pathogens commonly causing OM, with enhanced stability against common β-lactamases. The main objective of this study was to evaluate the in vitro activity of cefditoren against pathogens collected from the MEF of Costa Rican children with OM between 2006 and 2011. A total of 715 samples were analyzed. Among the 89 S. pneumoniae strains that were penicillin-nonsusceptible, only 7% were cefditoren-resistant according to Spanish Regulatory Agency criteria; among the H. influenza and M. catarrhalis isolates obtained, 100 and 90% of the isolates, respectively, were cefditoren-susceptible. MIC50/90 against the 207 PCV-13 S. pneumoniae serotyped strains and the 79 serotypes not covered by PCV-13 for cefditoren were 0.03/1 and 0.03/0.12 mg/l, respectively. For both amoxicillin-susceptible and resistant H. influenzae strains, the MIC range against cefditoren was from ≤0.015 to 0.06 mg/l as well. In conclusion, the confirmation of the wide spectrum of activity of cefditoren and its intrinsic strength against resistant strains allows us to suggest that cefditoren might be included as one of the best choices among antibiotics that are widely used in empiric therapy for OM in pediatric patients. © 2015 S.

    ABSTRACT: First-line epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) are effective for the treatment of lung adenocarcinoma with an EGFR-sensitizing mutation, but resistance is inevitable. Chemotherapy is widely used in the second-line setting. The outcome following this treatment scheme has not been thoroughly evaluated. From 2007 to 2011, consecutive patients with mutated EGFR receiving first-line TKI and second-line chemotherapy were retrospectively reviewed. The overall response was categorized into double responder, single responder and double nonresponder. Following this treatment scheme, baseline Eastern Cooperative Oncology Group (ECOG) performance status 0-1 (HR 0.60; 95% CI 0.37-0.98; p = 0.041) and double responder (HR 0.24; 95% CI 0.07-0.78; p = 0.018) were independent predictors of overall survival. Absence of pleural metastasis independently predicted the response to first-line TKI (OR 2.60; 95% CI 1.13-5.99; p = 0.025). In TKI responders, ECOG performance status 0-1 before chemotherapy (OR 4.95; 95% CI 1.15-21.28; p = 0.006), an exon 19 deletion (OR 4.74; 95% CI 1.30-17.21; p = 0.018) and progression-free survival (PFS) on first-line TKI (OR 1.02; 95% CI 1.01-1.09; p = 0.049) independently predicted the response to second-line chemotherapy. A moderate linear relationship (Pearson's r = 0.441; p = 0.001) existed between the PFS of this treatment scheme in TKI responders. The status of double responder to first-line TKI and second-line chemotherapy was predictive of improved survival in EGFR-mutated adenocarcinoma. © 2015 S. Karger AG, Basel.

    ABSTRACT: A phase I/II study of combination chemotherapy with amrubicin and nedaplatin for patients with untreated, advanced, non-small cell lung cancer (NSCLC) was conducted. Amrubicin was given on days 1-3, with nedaplatin given on day 1. The treatment was repeated every 3 weeks. In the phase I trial, the initial amrubicin dose of 25 mg/m(2) was escalated in 5-mg/m(2) increments until the maximum tolerated dose was reached, with the dose of nedaplatin fixed at 100 mg/m(2). In the phase II trial, the primary endpoint was the overall response rate (ORR), assuming 20% for a standard therapy and 40% for a target therapy (α = 0.05 and β = 0.20), and the estimated required total number of patients was 35. In the phase I study, nedaplatin 100 mg/m(2) and amrubicin 25 mg/m(2) was recommended. In the phase II study, 17 out of 35 patients achieved a partial response, and the ORR was 48.6%. Grade 3/4 neutropenia, grade 3 anemia and grade 3/4 thrombocytopenia occurred in 62.9, 11.4 and 11.4% of cycles, respectively. Febrile neutropenia occurred in 5 cycles (3.9%) and all cases were manageable. The recommended dose of this combination is well tolerated and effective in patients with advanced NSCLC. © 2015 S.

    ABSTRACT: To compare the efficacy of full-dose gemcitabine-based concurrent chemoradiotherapy (FG-CCRT) and conventional 5-fluorouracil CCRT (5FU-CCRT) for locally advanced pancreatic cancer (LAPC). 109 LAPC cases treated with FG-CCRT (n = 89) or 5FU-CCRT (n = 20) were reviewed retrospectively. The FG-CCRT group was composed of a full-dose gemcitabine monotherapy (1,000 mg/m(2)) arm and a combination therapy with cisplatin (70 mg/m(2)) arm. The 5FU-CCRT group used a radiosensitizing dose of 5-FU (500 mg/m(2)) plus leucovorin (20 mg/m(2)). Concurrent radiotherapy was targeted at the tumor with a 5-mm margin without lymph node irradiation. Objective response rate (ORR) and disease control rate (DCR) was significantly higher in the FG-CCRT group (ORR: 32.6 vs. 5%, p = 0.013; DCR: 79.8 vs. 50.0%, p = 0.006). FG-CCRT showed remarkable superiority to 5FU-CCRT for suppressing distant metastasis (18.0 vs. 45.0%, p = 0.017). Neutropenia (34.8 vs. 10%, p = 0.032) and thrombocytopenia (21.3 vs. 0.0%, p = 0.021) were more frequent in the FG-CCRT group as originally expected. When dividing the FG-CCRT group to gemcitabine monotherapy (GEM) and gemcitabine plus cisplatin, toxicities of the GEM subgroup were not different than those of the 5FU-CCRT group. FG-CCRT, especially full-dose gemcitabine monotherapy-based CCRT was more effective for the initial control of LAPC than 5FU-CCRT, and also relatively safe. © 2015 S. Karger AG, Basel.
