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.
Background Haemorrhagic cystitis (HC) is most commonly caused by intravenous chemotherapy drugs, notably cyclophosphamide, 1,2 administration of treatments directly into the bladder (e.g. bacillus Calmette-Guérin), 3,4 or radiation therapy to the pelvic area. 5 Cases of HC have also been reported with the use of other therapeutic agents, 2,6-9 recreational drugs 10 and environmental toxins. 11 HC has a spectrum of manifestations that range from non-visible (or microscopic) haematuria to gross (visible) haematuria with clots, 12 and has a reported incidence from less than 10% up to 35%. 4,5,13-15 Severe HC can be a challenging condition to treat and may give rise to serious complications, 16 leading to prolonged hospitalisation and occasional mortality. 12 Several reviews of the available preventive and therapeutic options for chemical-and radiation-induced cystitis
Recent investigations have suggested that levels of urinary tissue factor (UTF) may be elevated in some forms of cancer. We have determined UTF levels in healthy controls, patients presenting for surgery with benign prostatic hypertrophy (BPH) and untreated prostate cancer. Patients undergoing check cystoscopy, who were free of recurrent bladder cancer, and a cohort of men with bone scan positive prostate cancer recently treated by androgen ablation were also studied. UTF levels were higher in patients with prostate cancer when compared with controls, those undergoing check cystoscopy and patients with BPH. In patients with prostate cancer, bone scan positive patients had higher levels than bone scan negative subjects. The androgen ablated group had UTF levels similar to those of the control groups and significantly lower than the bone scan positive group. A weak correlation was found between UTF and serum prostate specific antigen (PSA) levels when patients with BPH and untreated cancer were analysed, but no correlation was demonstrable between PSA and UTF when cancer patients alone were evaluated. It was concluded that UTF levels are elevated in untreated prostate cancer and reflect bone scan status. In patients with bone scan positive disease UTF also reflects disease activity and may therefore be a useful disease marker in prostate cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
