Review
• To review the published data on predisposing risk factors for cancer treatment-induced haemorrhagic cystitis (HC) and the evidence for the different preventive and therapeutic measures that have been used in order to help clinicians optimally define and manage this potentially serious condition. • Despite recognition that HC can be a significant complication of cancer treatment, there is currently a lack of UK-led guidelines available on how it should optimally be defined and managed. • A systematic literature review was undertaken to evaluate the evidence for preventative measures and treatment options in the management of cancer treatment-induced HC. • There is a wide range of reported incidence due to several factors including variability in study design and quality, the type of causal agent, the grading of bleeding, and discrepancies in definition criteria. • The most frequently reported causal factors are radiotherapy to the pelvic area, where HC has been reported in up to 20% of patients, and treatment with cyclophosphamide and bacillus Calmette-Guérin, where the incidence has been reported as up to 30%. • Mesna (2-mercaptoethane sodium sulphonate), hyperhydration and bladder irrigation have been the most frequently used prophylactic measures to prevent treatment-related cystitis, but are not always effective. • Cranberry juice is widely cited as a preventative measure and sodium pentosanpolysulphate as a treatment, although the evidence for both is very limited. • The best evidence exists for intravesical hyaluronic acid as an effective preventative and active treatment, and for hyperbaric oxygen as an equally effective treatment option. • The lack of robust data and variability in treatment strategies used highlights the need for further research, as well as best practice guidance and consensus on the management of HC.

Review
Prevention and management of BK-virus associated haemorrhagic cystitis in children following haematopoietic stem cell transplantation--a systematic review and evidence-based guidance for clinical management.
Haemorrhagic cystitis (HC) is a common and, in its severe form, potentially life-threatening complication of Haematopoietic stem cell transplantation (HSCT) in children. Recent data indicate an important role of BK virus reactivation during the time of maximal post-transplant immune suppression in the pathogenesis of late-onset HC. Treatment of HC is mainly symptomatic and often frustrating. To give clinicians guidance on prevention and treatment options and their backing by scientific evidence, we have systematically assessed the available literature and devised evidence-based guidelines. Our comprehensive review demonstrates that evidence for the most commonly used interventions (such as cidofovir, oestrogen, hyperbaric oxygen, bladder instillation with formalin, alum salts or prostaglandin) is very limited. Some of these interventions also carry significant risks. Higher level evidence exists only for 2-mercaptoethane sodium (MESNA) and hyperhydration as a preventative intervention, and for systemic recombinant Factor VII as a treatment to stop acute haemorrhage. Further high-quality studies are required to establish effective and safe prevention and treatment options for HC.

Meta-Analysis Review
Inhaled mucoactive agents are used in respiratory disease to improve mucus properties and enhance secretion clearance. The effect of mannitol, recombinant human deoxyribonuclease/dornase alfa (rhDNase) and hypertonic saline (HS) or normal saline (NS) are not well described in chronic lung conditions other than cystic fibrosis (CF). The aim of this review was to determine the benefit and safety of inhaled mucoactive agents outside of CF. We searched Medline, Embase, CINAHL and CENTRAL for randomized controlled trials investigating the effects of mucoactive agents on lung function, adverse events (AEs), health-related quality of life (HRQOL), hospitalization, length of stay, exacerbations, sputum clearance and inflammation. There were detrimental effects of rhDNase in bronchiectasis, with average declines of 1.9-4.3% in forced expiratory volume in 1 s (FEV ) and 3.7-5.4% in forced vital capacity (FVC) (n = 410, two studies), and increased exacerbation risk (relative risk = 1.35, 95% CI = 1.01-1.79 n = 349, one study). Some participants exhibited a reduction in FEV (≥10-15%) with mucoactive agents on screening (mannitol = 158 of 1051 participants, rhDNase = 2 of 30, HS = 3 of 80). Most AEs were mild and transient, including bronchospasm, cough and breathlessness. NS eased symptomatic burden in COPD, while NS and HS improved spirometry, HRQOL and sputum burden in non-CF bronchiectasis. Mannitol improved mucociliary clearance in asthma and bronchiectasis, while the effects of N-acetylcysteine were unclear. In chronic lung diseases outside CF, there are small benefits of mannitol, NS and HS. Adverse effects of rhDNase suggest this should not be administered in non-CF bronchiectasis.

Review
Dose-intensive chemotherapy with growth factor or autologous bone marrow/stem cell transplant support in first-line treatment of advanced or metastatic adult soft tissue sarcoma: a systematic review.
A systematic review was performed to determine whether first-line dose-intensive chemotherapy supported by growth factor or autologous bone marrow/stem cell transplantation improves response rate, time-to-disease progression, or survival compared with standard-dose chemotherapy in patients with inoperable, locally advanced, or metastatic soft tissue sarcoma. The MEDLINE, EMBASE, and Cochrane Library databases were searched. Three randomized trials (2 phase 3, 1 phase 2), 12 phase 2, and 5 phase 1 dose-escalation trials were located. One randomized trial (N=314) did not detect significant differences in response rate (P=.65) or survival (log-rank P=.98) between high-dose doxorubicin plus ifosfamide with granulocyte macrophage colony-stimulating factor and doxorubicin plus ifosfamide at standard doses. Progression-free survival, however, was significantly longer in the high-dose arm (log-rank P=.03). Higher rates of thrombocytopenia, infection, grade 3 of 4 asthenia, and stomatitis were observed with high-dose compared with standard-dose chemotherapy. Preliminary results from a second randomized trial (N=162) indicated no benefit with respect to tumor response for an intensified mesna, doxorubicin (Adriamycin), ifosfamide, and dacarbazine regimen with granulocyte colony-stimulating factor support compared with standard doxorubicin, ifosfamide, and dacarbazine. Grade 4 thrombocytopenia was significantly higher with the high-dose regimen. Four phase 2 trials of high-dose regimens observed tumor response rates greater than 50%. Phase 1 trials reported dose-limiting toxicity for dose-intensive chemotherapy regimens. On the basis of the available evidence, high-dose chemotherapy with growth factor or autologous bone marrow/stem cell transplantation should not be used in the routine treatment of patients with inoperable, locally advanced, or metastatic soft tissue sarcoma.
