ABSTRACT

BACKGROUND: Clinical trials in metastatic colorectal cancer (mCRC) are usually conducted irrespective of sex. Sex-associated differences relating to safety and efficacy in the treatment of mCRC, however, are gaining interest. METHODS: PanaMa investigated the efficacy of panitumumab (Pmab) plus fluorouracil and folinic acid (FU/FA) versus FU/FA alone after induction therapy with six cycles of FU/FA and oxaliplatin plus Pmab in patients with RAS wild-type mCRC. In this post hoc analysis, the study population was stratified for sex. Evaluated efficacy endpoints during maintenance treatment were progression-free survival (PFS, primary endpoint of the trial), overall survival (OS) and objective response rate during maintenance therapy. Safety endpoints were rates of any grade and grade 3/4 adverse events during maintenance therapy. RESULTS: In total, 165 male and 83 female patients were randomized and treated. Male and female patients showed numerically better objective response rates with Pmab, without reaching statistical significance. Male patients derived a significant benefit from the addition of Pmab to maintenance treatment with regard to PFS [hazard ratio (HR) 0.63; 95% confidence interval (CI) 0.45-0.88; P = 0.006] that was not observed in female patients (HR 0.85; 95% CI 0.53-1.35; P = 0.491). The better PFS for male patients treated with Pmab did not translate into improved OS (HR 0.85; 95% CI 0.55-1.30; P = 0.452). Female patients showed numerically improved OS when treated with Pmab. There was no difference in the total of grade ≥3 adverse events during maintenance regarding sex (P = 0.791). Female patients, however, had a higher rate of any grade nausea, diarrhea and stomatitis. CONCLUSIONS: In the PanaMa trial, the addition of Pmab to maintenance treatment of RAS wild-type mCRC with FU/FA improved the outcome in terms of the primary endpoint (PFS) particularly in male patients. Female patients did not show the same benefit while experiencing higher rates of adverse events. Our results support the development of sex-specific protocols.

ABSTRACT

BACKGROUND: Initial systemic therapy for patients with metastatic colorectal cancer (mCRC) is usually based on two- or three-drug chemotherapy regimens with fluoropyrimidine (5-fluorouracil (5-FU) or capecitabine), oxaliplatin and/or irinotecan, combined with either anti-VEGF (bevacizumab) or, for RAS wild-type (WT) tumors, anti-EGFR antibodies (panitumumab or cetuximab). Recommendations for patients who are not eligible for intensive combination therapies are limited and include fluoropyrimidine plus bevacizumab or single agent anti-EGFR antibody treatment. The use of a monochemotherapy concept of trifluridine/ tipiracil in combination with monoclonal antibodies is not approved for first-line therapy, yet. Results from the phase II TASCO trial evaluating trifluridine/ tipiracil plus bevacicumab in first-line treatment of mCRC patients and from the phase I/II APOLLON trial investigating trifluridine/ tipiracil plus panitumumab in pre-treated mCRC patients suggest favourable activity and tolerability of these new therapeutic approaches. METHODS: FIRE-8 ( NCT05007132 ) is a prospective, randomized, open-label, multicenter phase II study which aims to evaluate the efficacy of first-line treatment with trifluridine/tipiracil (35 mg/m2 body surface area (BSA), orally twice daily on days 1-5 and 8-12, q28 days) plus either the anti-EGFR antibody panitumumab (6 mg/kg body weight, intravenously on day 1 and 15, q28 days) [arm A] or (as control arm) the anti-VEGF antibody bevacizumab (5 mg/kg body weight, intravenously on day 1 and 15, q28 days) [arm B] in RAS WT mCRC patients. The primary objective is to demonstrate an improved objective response rate (ORR) according to RECIST 1.1 from 30% (control arm) to 55% with panitumumab. With a power of 80% and a two-sided significance level of 0.05, 138 evaluable patients are needed. Given an estimated drop-out rate of 10%, 153 patients will be enrolled. DISCUSSION: To the best of our knowledge, this is the first phase II trial to evaluate the efficacy of trifluridine/tipiracil plus panitumumab in first-line treatment of RAS WT mCRC patients. The administration of anti-EGFR antibodies rather than anti-VEGF antibodies in combination with trifluridine/tipiracil may result in an increased initial efficacy.

ABSTRACT

INTRODUCTION: Trifluridine/tipiracil (FTD/TPI) improved both overall and progression-free survival (OS, PFS) of patients with pre-treated metastatic colorectal cancer (mCRC) in the pivotal phase III RECOURSE trial. However, health-related quality of life (HRQoL) was not assessed directly. To this end and to generate post-authorisation data, the TALLISUR trial was conducted. METHODS: In this prospective, multi-centre, Germany-wide, phase IV study, patients with pre-treated mCRC were given the choice to receive either FTD/TPI or best supportive care (BSC). A validated questionnaire, EORTC QLQ-C30, was employed to assess HRQoL. Secondary endpoints included OS, PFS and safety. RESULTS: Of 194 eligible patients, 185 decided to receive FTD/TPI and 9 to receive BSC. The low number of patients in the BSC-arm did not allow statistically meaningful analyses. On the other hand, treatment with FTD/TPI was associated with maintained HRQoL. Median OS was 6.9 months [95% confidence interval (CI) 6.1-8.2 months] and median PFS was 2.5 months (95% CI 2.1-2.9 months). The most frequent treatment-emergent adverse events were neutropenia (27.6%) and anaemia (22.7%). Febrile neutropenia occurred in 1.1%. CONCLUSIONS: Treatment of patients suffering from pre-treated mCRC with FTD/TPI was associated not only with prolonged survival and delayed progression but also with maintained HRQoL.

ABSTRACT

PURPOSE: Chemotherapy-induced nausea and vomiting (CINV) remain significant clinical problems, especially in the delayed phase (24-120 h after chemotherapy). Amisulpride is a dopamine D2/D3-receptor antagonist previously shown to be an effective intravenous antiemetic. We conducted a randomised, double-blind study to characterise the dose response of oral amisulpride in delayed phase CINV. METHODS: Chemotherapy-naïve patients receiving cisplatin ≥ 70 mg/m2 or an anthracycline-cyclophosphamide regimen for breast cancer received, on day 1, 20 mg amisulpride and 8-16 mg ondansetron intravenously followed, once daily on days 2-4, by 10, 20 or 40 mg oral amisulpride or placebo. A control group receiving standard three-drug prophylaxis was enrolled for assay sensitivity purposes. The primary endpoint was complete response (CR), defined as no emesis or rescue medication use, in the delayed phase. RESULTS: Three hundred eighteen subjects were evaluable per protocol. CR rate (24-120 h) was 20% with placebo and 46% with 10 mg amisulpride (p = 0.006 after multiplicity adjustment); in the three-drug control group, it was 59%. Emesis, nausea and 0-120-h CR rate were significantly improved with 10 mg amisulpride compared to placebo. Higher doses of amisulpride were not more effective than 10 mg. In patients with acute phase CR, delayed phase CR rate was 44% for placebo, 75% for 10 mg amisulpride (p = 0.022) and 70% for the 3-drug control. No significant differences were seen between groups in safety parameters. CONCLUSIONS: Amisulpride 10 mg orally is safe and superior to placebo at preventing delayed CINV caused by highly emetogenic chemotherapy. TRIAL REGISTRATION: NCT01857232.

ABSTRACT

Background: NEPA, an oral fixed combination of the NK1RA netupitant (300 mg) and clinically/pharmacologically distinct 5-HT3RA palonosetron (PALO, 0.50 mg), is the first fixed antiemetic combination to have been approved. A single oral NEPA capsule plus dexamethasone (DEX) given before anthracycline-cyclophosphamide (AC) and non-AC highly emetogenic chemotherapy (HEC) showed superior prevention of chemotherapy-induced nausea and vomiting (CINV) over PALO plus DEX for 5 days postchemotherapy. The safety of NEPA was well-established in the phase II/III clinical program in 1169 NEPA-treated patients. An intravenous (i.v.) formulation of the NEPA combination (fosnetupitant 235 mg plus PALO 0.25 mg) has been developed. Patients and methods: This randomized, multinational, double-blind, stratified (by sex and country) phase III study (NCT02517021) in chemotherapy-naïve patients with solid tumors assessed the safety of a single dose of i.v. NEPA infused over 30 min before initial and repeated cycles of HEC. Patients received either i.v. NEPA or oral NEPA, both with oral DEX on days 1-4. Safety was assessed primarily by treatment-emergent adverse events (AEs) and electrocardiograms. Results: A total of 404 patients completed 1312 cycles. The incidence and type of treatment-emergent AEs were similar for both treatment groups with the majority of AEs as mild/moderate in intensity. There was no increased incidence of AEs in subsequent cycles in either group. The incidence of treatment-related AEs was similar and relatively low in both groups (12.8% i.v. NEPA and 11.4% oral NEPA during the entire study), with constipation being the most common (6.4% i.v. NEPA, 6.0% oral NEPA). No serious treatment-related AEs occurred in either group. No infusion site or anaphylactic reactions related to i.v. NEPA occurred. No clinically relevant changes in QTc and no cardiac safety concerns were observed. Conclusions: Intravenous NEPA was well-tolerated with a similar safety profile to oral NEPA in patients with various solid tumors receiving HEC.

ABSTRACT

Background: Mutations in rat sarcoma (RAS) genes may be a mechanism of secondary resistance in epidermal growth factor receptor inhibitor-treated patients. Tumor-tissue biopsy testing has been the standard for evaluating mutational status; however, plasma testing of cell-free DNA has been shown to be a more sensitive method for detecting clonal evolution. Materials and methods: Archival pre- and post-treatment tumor biopsy samples from a phase II study of panitumumab in combination with irinotecan in patients with metastatic colorectal cancer (mCRC) that also collected plasma samples before, during, and after treatment were analyzed for emergence of mutations during/post-treatment by next-generation sequencing and BEAMing. Results: The rate of emergence of tumor tissue RAS mutations was 9.5% by next-generation sequencing (n = 21) and 6.3% by BEAMing (n = 16). Plasma testing of cell-free DNA by BEAMing revealed a mutant RAS emergence rate of 36.7% (n = 39). Exploratory outcomes analysis of plasma samples indicated that patients who had emergent RAS mutations at progression had similar median progression-free survival to those patients who remained wild-type at progression. Serial analysis of plasma samples showed that the first detected emergence of RAS mutations preceded progression by a median of 3.6 months (range, -0.3 to 7.5 months) and that there did not appear to be a mutant RAS allele frequency threshold that could predict near-term outcomes. Conclusions: This first prospective analysis in mCRC showed that serial plasma biopsies are more inclusive than tissue biopsies for evaluating global tumor heterogeneity; however, the clinical utility of plasma testing in mCRC remains to be further explored.

ABSTRACT

Fever may be the only clinical symptom at the onset of infection in neutropenic cancer patients undergoing myelosuppressive chemotherapy. A prompt and evidence-based diagnostic and therapeutic approach is mandatory. A systematic search of current literature was conducted, including only full papers and excluding allogeneic hematopoietic stem cell transplant recipients. Recommendations for diagnosis and therapy were developed by an expert panel and approved after plenary discussion by the AGIHO. Randomized clinical trials were mainly available for therapeutic decisions, and new diagnostic procedures have been introduced into clinical practice in the past decade. Stratification into a high-risk versus low-risk patient population is recommended. In high-risk patients, initial empirical antimicrobial therapy should be active against pathogens most commonly involved in microbiologically documented and most threatening infections, including Pseudomonas aeruginosa, but excluding coagulase-negative staphylococci. In patients whose expected duration of neutropenia is more than 7 days and who do not respond to first-line antibacterial treatment, specifically in the absence of mold-active antifungal prophylaxis, further therapy should be directed also against fungi, in particular Aspergillus species. With regard to antimicrobial stewardship, treatment duration after defervescence in persistently neutropenic patients must be critically reconsidered and the choice of anti-infective agents adjusted to local epidemiology. This guideline updates recommendations for diagnosis and empirical therapy of fever of unknown origin in adult neutropenic cancer patients in light of the challenges of antimicrobial stewardship.

ABSTRACT

BACKGROUND: Central venous catheter (CVC)-related bloodstream infections (CRBSI) are a frequent cause of morbidity and mortality in patients with chemotherapy-induced neutropenia. Chlorhexidine containing catheter securement dressings may prevent CRBSI. PATIENTS AND METHODS: A multicenter randomized, controlled trial was conducted at 10 German hematology departments. We compared chlorhexidine-containing dressings with non-chlorhexidine control dressings in neutropenic patients. The primary end point was the incidence of definite CRBSI within the first 14 days (dCRBSI14) of CVC placement. Secondary end points included combined incidence of definite or probable CRBSI within 14 days (dpCRBSI14), overall (dpCRBSI), incidence of unscheduled dressing changes and adverse events. RESULTS: From February 2012 to September 2014, 613 assessable patients were included in the study. The incidence of dCRBSI14 was 2.6% (8/307) in the chlorhexidine and 3.9% (12/306) in the control group (P = 0.375). Both dpCRBSI14 and dpCRBSI were significantly less frequent in the study group with dpCRBSI14 in 6.5% (20/307) of the chlorhexidine group when compared with 11% (34/306) in the control group (P = 0.047), and dpCRBSI in 10.4% (32/307) versus 17% (52/306), respectively (P = 0.019). The frequency of dressing intolerance with cutaneous and soft tissue abnormalities at the contact area was similar in both groups (12.4% and 11.8%; P = 0.901). CONCLUSIONS: Although the trial failed its primary end point, the application of chlorhexidine containing catheter securement dressings reduces the incidence of definite or probable CRBSI in neutropenic patients. CLINICAL TRIALS NUMBER: NCT01544686 (Clinicaltrials.gov).

ABSTRACT

BACKGROUND: Antiemetic guidelines recommend co-administration of agents that target multiple molecular pathways involved in emesis to maximize prevention and control of chemotherapy-induced nausea and vomiting (CINV). NEPA is a new oral fixed-dose combination of 300 mg netupitant, a highly selective NK1 receptor antagonist (RA) and 0.50 mg palonosetron (PALO), a pharmacologically and clinically distinct 5-HT3 RA, which targets dual antiemetic pathways. PATIENTS AND METHODS: This multinational, randomized, double-blind, parallel group phase III study (NCT01339260) in 1455 chemotherapy-naïve patients receiving moderately emetogenic (anthracycline-cyclophosphamide) chemotherapy evaluated the efficacy and safety of a single oral dose of NEPA versus a single oral dose (0.50 mg) of PALO. All patients also received oral dexamethasone (DEX) on day 1 only (12 mg in the NEPA arm and 20 mg in the PALO arm). The primary efficacy end point was complete response (CR: no emesis, no rescue medication) during the delayed (25-120 h) phase in cycle 1. RESULTS: The percentage of patients with CR during the delayed phase was significantly higher in the NEPA group compared with the PALO group (76.9% versus 69.5%; P = 0.001), as were the percentages in the overall (0-120 h) (74.3% versus 66.6%; P = 0.001) and acute (0-24 h) (88.4% versus 85.0%; P = 0.047) phases. NEPA was also superior to PALO during the delayed and overall phases for all secondary efficacy end points of no emesis, no significant nausea and complete protection (CR plus no significant nausea). NEPA was well tolerated with a similar safety profile as PALO. CONCLUSIONS: NEPA plus a single dose of DEX was superior to PALO plus DEX in preventing CINV following moderately emetogenic chemotherapy in acute, delayed and overall phases of observation. As a fixed-dose antiemetic drug combination, NEPA along with a single dose of DEX on day 1 offers guideline-based prophylaxis with a convenient, single-day treatment.

ABSTRACT

BACKGROUND: Current evidence on myelopoietic growth factors is difficult to overview for the practicing haematologist/oncologist. International guidelines are sometimes conflicting, exclude certain patient groups, or cannot directly be applied to the German health system. This guideline by the Infectious Diseases Working Party (AGIHO) of the German Society of Haematology and Medical Oncology (DGHO) gives evidence-based recommendations for the use of G-CSF, pegylated G-CSF, and biosimilars to prevent infectious complications in cancer patients undergoing chemotherapy, including those with haematological malignancies. METHODS: We systematically searched and evaluated current evidence. An expert panel discussed the results and recommendations. We then compared our recommendations to current international guidelines. RESULTS: We summarised the data from eligible studies in evidence tables, developed recommendations for different entities and risk groups. CONCLUSION: Comprehensive literature search and expert panel consensus confirmed many key recommendations given by international guidelines. Evidence for growth factors during acute myeloid leukaemia induction chemotherapy and pegfilgrastim use in haematological malignancies was rated lower compared with other guidelines.

ABSTRACT

BACKGROUND: Cancer patients are at increased risk for central venous catheter-related infections (CRIs). Thus, a comprehensive, practical and evidence-based guideline on CRI in patients with malignancies is warranted. PATIENTS AND METHODS: A panel of experts by the Infectious Diseases Working Party (AGIHO) of the German Society of Hematology and Medical Oncology (DGHO) has developed a guideline on CRI in cancer patients. Literature searches of the PubMed, Medline and Cochrane databases were carried out and consensus discussions were held. RESULTS: Recommendations on diagnosis, management and prevention of CRI in cancer patients are made, and the strength of the recommendation and the level of evidence are presented. CONCLUSION: This guideline is an evidence-based approach to the diagnosis, management and prevention of CRI in cancer patients.

ABSTRACT

Invasive fungal infections (IFIs) are a primary cause of morbidity and mortality in patients with hematological malignancies. Establishing a definite diagnosis of IFI in immunocompromised patients is particularly challenging and time consuming, but delayed initiation of antifungal treatment increases mortality. The limited overall outcome has led to the strategy of initiating either 'empirical' or 'preemptive' antifungal therapy before the final diagnosis. However, diagnostic procedures have been vastly improved in recent years. Particularly noteworthy is the introduction of newer imaging techniques and non-culture methods, including antigen-based assays, metabolite detection and molecular detection of fungal DNA from body fluid samples. Though varying widely in cancer patients, the risk of IFI is highest in those with allogeneic stem cell transplantation and those with acute leukemia. The AGIHO presents recommendations for the diagnosis of IFIs with risk-adapted screening concepts for febrile episodes in patients with haemato-oncological disorders.

ABSTRACT

Our objective was to evaluate the maximum tolerated dose of caspofungin for invasive aspergillosis (IA). The safety and pharmacokinetics of escalating dosages of caspofungin were investigated in IA. Eight patients each received caspofungin 70, 100, 150, or 200 mg once a day (QD). Dose-limiting toxicity (DLT) was defined as the same non-hematological treatment-related adverse event of grade ≥ 4 in 2 of 8 patients or ≥ 3 in 4 of 8 patients in a cohort. A total of 46 patients (median age, 61 years; 21 female; 89% with hematological malignancies) received caspofungin (9, 8, 9, and 20 patients in the 70-, 100-, 150-, and 200-mg cohorts) for a median of 24.5 days. Plasma pharmacokinetics were linear across the investigated dosages and followed a two-compartment model, with weight as the covariate on clearance and sex as the covariate on central volume of distribution. Simulated peak plasma concentrations at steady state ranged from 14.2 to 40.6 mg/liter (28%), trough concentrations from 4.1 to 11.8 mg/liter (58%), and area under the concentration-time curve from 175 to 500 mg/liter/h (32%) (geometric mean, geometric coefficient of variation). Treatment was well tolerated without dose-limiting toxicity. The rate of complete or partial responses was 54.3%, and the overall mortality at 12-week follow-up was 28.3%. In first-line treatment of invasive aspergillosis, daily doses of up to 200 mg caspofungin were well tolerated and the maximum tolerated dose was not reached. Pharmacokinetics was linear. Response rates were similar to those previously reported for voriconazole and liposomal amphotericin.

ABSTRACT

The objectives of this study were to identify unsolved issues in the management of invasive candidiasis, identify controversies and achieve consensus. The German Speaking Mycological Society (Deutschsprachige Mykologische Gesellschaft, DMykG e.V.) asked other German infectious diseases (ID) and mycological societies to submit unsolved issues concerning the diagnosis and treatment of fungal infections. Based on these contributions, a digital web-based questionnaire of 12 questions on Candida infections was designed to be completed by experts of the participating societies. Controversial results were identified by a mathematical model and were discussed at a consensus conference during the 43rd Annual Meeting of the DMykG e.V. in Cologne, Germany. Forty-two individuals completed the questionnaire. Analysis showed a strong consensus on treatment indications, choice of antifungals for clinical situations, handling of central venous catheters, duration of treatment and role of susceptibility testing. Opinions diverged on: initial treatment of haemodynamically stable neutropenic and haemodynamically unstable non-neutropenic patients, step down to oral treatment and the differential role of the echinocandins. These questions were presented for discussion at the expert consensus conference. In three of four questions, consensus was achieved. A two-step approach - web-based survey plus classical panel discussion - allows to capture expeditiously the opinions of a large and diverse group of individuals, to identify controversial issues and to resolve them in a personal, interactive setting. Thus, expert consensus was achieved on nine of 12 important questions on how to treat invasive candidiasis.

ABSTRACT

Major progress for the management of invasive aspergillosis has come from the introduction of new antifungals since the late 1990s. Although mortality of invasive aspergillosis remains as high as 30-50%. Backbone of management are prophylaxis, early diagnosis and early initiation of antifungals for reduction of invasive aspergillosis related mortality. Randomized trials have been undertaken for the prophylaxis as well as treatment of invasive aspergillosis in the last two decades. Posaconazole is recommended for prophylaxis against aspergillosis in patients treated for acute myelogenous leukemia, myelodysplastic syndrome or patients with graft versus host disease after allogeneic transplantation. Efficacy has been shown for first-line therapy of invasive aspergillosis with voriconazole and liposomal amphotericin B. Gastrointestinal resorption for the azoles posaconazole, voriconazole and itraconazole differ considerably. While oral voriconazole resportion is reduced when taken with food, posaconazole has to be taken with fatty food for optimal intestinal resorption. Beside all advances in the management of invasive aspergillosis important questions remain unresolved. This article reviews the current state of prophylaxis and treatment of invasive aspergillosis and points out clinicians unmet needs.

ABSTRACT

BACKGROUND: Anti-epidermal growth factor receptor treatment strategies, i.e. monoclonal antibodies such as cetuximab and panitumumab, or epidermal growth factor receptor (EGFR) small molecule tyrosine kinase inhibitors, such as erlotinib and gefitinib, have expanded the treatment options for different tumor types. Dermatologic toxic effects are the most common side-effects of EGFR inhibitor therapy. They can profoundly affect the patient's quality of life. PURPOSE: The aim of this study was to provide interdisciplinary expert recommendations on how to treat patients with skin reactions undergoing anti-EGFR treatment. MATERIAL AND METHODS: An expert panel from Germany with expertise in medical oncology, dermatology or clinical pharmacology was convened to develop expert recommendations based on published peer-reviewed literature. RESULTS: The expert recommendations for the state-of-the-art treatment of skin reactions induced by EGFR inhibitor therapy include recommendations for diagnostics and grading as well as grade-specific and stage-adapted treatment approaches and preventive measures. It was concluded that EGFR-inhibitor-related dermatologic reactions should always be treated combining basic care of the skin and a specific therapy adapted to stage and grade of skin reaction. For grade 2 and above, specific treatment recommendations for early- and later-stage skin reactions induced by EGFR-inhibitor therapy were proposed. CONCLUSION: This paper presents a German national expert opinion for the treatment of skin reactions in patients receiving EGFR inhibitor therapy.

ABSTRACT

Sepsis is a leading cause of death in the intensive care unit (ICU), with Candida spp. in the forefront among the important pathogens. As recent studies have shown, survival outcome is strongly influenced by adequate antifungal therapy at an early stage that is often delayed by the time lag associated with microbiological diagnosis. Risk factor-based prediction models have a high negative predictive value, but positive prediction of candidaemia in the individual patient remains elusive. New antigen- or DNA-based methods for early diagnosis still await clinical validation. Their routine use is hampered by methodological issues. Species distribution of invasive Candida isolates in the ICU appears to be influenced primarily by age, previous hospitalisation and colonising species. In the context of the importance of adequate first-line treatment, recent guidelines favour the use of echinocandins in critically ill patients with symptoms evoking high suspicion of invasive candidiasis. This is supported by robust clinical trial data, a few interactions and low toxicity. Fluconazole is characterised by reduced activity against some important Candida species, elevated rates of persistent infection seen in comparative trials. Amphotericin B deoxycholate should be considered obsolete in ICU patients because of its high toxicity. Invasive aspergillosis (IA) is a rare devastating infection in the general ICU population, but some centres have reported elevated incidences and underdiagnosis as determined in autopsy-controlled studies. Treatment with mould-active agents such as voriconazole must be initiated early in patients with suspected IA.

ABSTRACT

Invasive fungus infections caused by aspergillus spp. occur most frequently in immunocompromised patients. A high infection-associated death rate of up to and over 50% is attributed even today to these fungi. The disease in humans is caused mainly by Aspergillus fumigatus, Aspergillus flavus and Aspergillus niger. Other species, for example, Aspergillus terreus or Aspergillus nidulans are quantitatively less prevalent. Evidence based treatment of invasive aspergillosis has become safer and more effective within the last ten years through the introduction of the new azoles and the echinocandines. Voriconazole has become the medication of choice for initial therapy. The efficacy of voriconazole is well documented, to include the treatment of disseminated infections of the central nervous system. Amphotericin B-desoxycholate is associated with definite side-effects in intravenous therapy. On the grounds of its substantial toxicity, the North American Infectious Disease Society's (IDSA) Guidelines of 2008 recommend amphotericin B-desoxycholate for regions with restricted resources only, which could be the case in underdeveloped countries. Liposomal amphotericin B in the daily standard dose of 3 mg/kg offers a rate of response similar to the one with voriconazole in the first-line treatment of invasive aspergillosis. However, a direct comparison with voriconazole on the basis of randomized studies is not available. As a secondary therapeutic treatment, in case of failure or intolerance of the primary treatment, caspofungin, micafungin and posaconazole have recently been under study. Both the echinocandines and posaconazole have proven effective in daily clinical practise. In refractory cases of invasive aspergillosis a combination therapy has been employed clinically. The results of prospective comparative controlled studies on combination therapy versus monotherapy will not be available until after 2010.

ABSTRACT

BACKGROUND: Cancer patients receiving chemotherapy experience thromboembolic complications associated with the use of long-term indwelling central venous catheters (CVCs). This prospective, double-blind, placebo-controlled, multicenter study evaluated whether prophylactic treatment with a low molecular weight heparin could prevent clinically relevant catheter-related thrombosis. PATIENTS AND METHODS: Patients with cancer undergoing chemotherapy for at least 12 weeks (n=439) were randomly assigned, in a 2:1 ratio, to receive either dalteparin (5000 IU) or placebo, by subcutaneous injection, once daily for 16 weeks. Patients underwent upper extremity evaluation with either venography or ultrasound at the time of a suspected catheter-related complication (CRC) or upon completion of study medication. The primary end point, as determined by a blinded adjudication committee, was the occurrence of a CRC, defined as the first occurrence of any one of the following: clinically relevant catheter-related thrombosis that was symptomatic or that required anticoagulant or fibrinolytic therapy; catheter-related clinically relevant pulmonary embolism; or catheter obstruction requiring catheter removal. RESULTS: There was no significant difference in the frequency of CRCs between the dalteparin arm (3.7%) and the placebo arm (3.4%; P=0.88), corresponding to a relative risk of 1.0883 (95% confidence interval 0.37-3.19). No difference in the time to CRC was observed between the two arms (P=0.83). There was no significant difference between the dalteparin and placebo groups in terms of major bleeding (1 versus 0) or overall safety. CONCLUSIONS: Dalteparin prophylaxis did not reduce the frequency of thromboembolic complications after CVC implantation in cancer patients. Dalteparin was demonstrated to be safe over 16 weeks of treatment in these patients.
