Urological and Testicular Research
Chairman: Professor Alan Horwich
Head of Unit: Professor David P Dearnaley MA MD FRCP FRCR
This multidisciplinary Unit focuses on the management of, and research involving, patients with testicular, prostate, bladder and renal cancers. Urological surgery is based in Chelsea and the associated specialised ward also co-ordinates stoma care. The chemotherapy of testicular and bladder cancers is undertaken predominantly in Sutton with clinical research data co-ordinated by the Bob Champion Cancer Trust Research Unit. The problems of urological tumours are extremely diverse. For example, although uncommon, testicular cancers are the most frequent malignancy occurring in young adult males and are increasing in incidence.
However, they are a model for chemo-sensitive cancer and the majority of men are cured. Prostate cancer is now the most common cancer in more elderly men. Treatment of localised disease is highly controversial and progressive advanced disease is often associated with widespread incurable bone metastases.
Over the last decade The Institute and Royal Marsden teams have developed an extensive portfolio of clinical and laboratory research in urological cancers. The national importance (and previous neglect) of prostate cancer has been the development of the National Prostate Cancer Programme and establishment of two national 'Centres of Excellence' for prostate cancer research. As a result of our previous track record and current research proposals, The Institute and Royal Marsden teams were invited to form the core of one of these with colleagues from Brunel and Liverpool Universities. This Cancer Collaborative, led by Professor Colin Cooper has won major support from the Cancer Research Funders' Forum to develop a 5-year programme in translational research including:
- Molecular pathology of prostate cancer
- Novel therapies for prostate cancer
- Aetiology of prostate cancer
Relevance to the NHS Research and Development Programme
The Unit has large referral practices for prostate and testicular tumours as well as for bladder and renal cancer. The Unit is particularly fortunate to be able to take advantage of a broad range of clinical specialists excellently supported by specialised pathology and radiology services. Our research programme makes significant contributions to many areas of the NHS R&D priorities in cancer, including the study of the genetics of testicular and prostate cancer, conformal radiotherapy, high dose chemotherapy and peripheral blood stem cell support for testicular cancer. Also our studies on neoadjuvant treatments in prostate cancer, extending nursing roles, and psycho-social intervention in males with cancers are areas which qualify as of very high or high importance to the NHS.
Recent personal achievements include the conferment of title of Reader in Cancer Genetics to Dr Ros Eeles and of Professor of Uro-Oncology to David Dearnaley. Dr Johann de Bono has been appointed Senior Lecturer in the Department of Medicine and will work on Phase I and II clinical trials within the Urology Unit particularly developing new targets in prostate cancer. Dr Vincent Khoo has been appointed Consultant Clinical Oncologist and will lead the non-surgical oncology team in in Chelsea. Dr Chris Parker and Professor Colin Cooper have become members of the Prostate Cancer Advisory Group where Dr Parker chairs the Committee developing decision tools for the management of localised prostate cancer. The Unit's genetics (lead Dr Ros Eeles) and clinical studies in prostate cancer have made leading contributions to the recruitment of patients through the National Cancer Research Network portfolio of trials in urological cancer research both nationally and in the South West Thames Cancer Network. The Academic Unit Quinquennial CR-UK programme grant (lead Professor Alan Horwich) gained 'Forefront/Outstanding' ratings. Development of conformal and intensity modulated radiotherapy programmes have been supported by a Department of Health grant to support a Phase III trial of hypofractionated treatment (PI Professor David Dearnaley). Major laboratory research publications include the identification of a gene called E2F3 in the development of bladder cancer (Professor Colin Cooper), confirmation that BRCA2 is a susceptibility gene for prostate cancer (Dr Ros Eeles) and identification of over-expressed sequences in chromosome 12p in testicular cancer (Dr Janet Shipley). Major published clinical studies include the evaluation of intensive induction chemotherapy in testicular cancer and identification of cardiovascular disease as a long term treatment complication in germ cell tumours (Dr Robert Huddart and colleagues) and the first Phase III trial evaluating bisphosphonate drugs in prostate cancer (Professor Dearnaley).
Future Aims
The Male Cancer Research Centre, 'Centre of Excellence' Collaborative Grant and Everyman Campaign provide unique opportunities to develop public awareness of male cancers and to translate high quality laboratory research into clinical benefit for patients. In prostate cancer we aim to develop genetic markers to determine the natural history of disease on an individual basis, so as to select appropriate management policies. Genetic studies will continue in both testicular and prostate cancer with the aim of identifying the gene(s) responsible for familial cancers. The Unit is ideally placed, because of its strong links with the Joint Department of Physics and large prostate cancer referral practice, to continue its national role in developing and assessing the use of conformal and intensity modulated radiotherapy in localised prostate cancer. The new impetus for clinical trials given by the development of the National Cancer Research Institute's Study Groups (Prostate Cancer Chair: D Dearnaley, Renal Cancer Chair: M Gore, Testis Cancer Chair: R Huddart) and National Cancer Research Network brings the responsibility for developing a portfolio of national trials for these urological cancers. The Active Surveillance Programme led by Dr C Parker will give new insights into disease behaviour and correlating predictive factors including tissue hypoxia and proteomics with disease progression and lead to opportunities for novel interventions. New targets will be evaluated in Phase I and II studies in collaboration with Dr de Bono.
TESTICULAR TUMOURS
Many patients referred to the Unit take part in prospective randomised trials co-ordinated by the MRC/EORTC. Major studies completed in 2003 include an assessment of intensive induction chemotherapy schedule CBOP-BEP for men with poor prognosis metastatic germ cell tumours. 5-year survivorship of 88% has been seen which compares very favourably with standard chemotherapy schedules (Christian et al, J Clin Oncol 21.871.2003). Further analysis of patient cohorts who have undergone prolonged follow up has identified cardiovascular disease to be a long-term complication of testicular cancer treatment emphasising the need to minimise therapy in good risk patients (Huddart et al, J Clin Oncol. 21.1513.2003). In the laboratory Janet Shipley's team have identified the over-expressed sequences of genes from chromosome 12p which are candidate genes for the development of testicular cancer (Rodriquez et al, Oncogene 22. 1880. 2003).

PROSTATE CANCER
Localised Disease
A programme of active surveillance (lead Dr C Parker) has rapidly recruited patients and has generated considerable interest and support both from within our Cancer Network and nationally. Opportunities to develop 'tertiary' prevention strategies will be explored. Clinical studies of the use of MRI in the development of new radiotherapy strategies has been supported by a Department of Health New and Emerging Applications of Technology (NEAT) grant. Localisation studies using ultrasound and implantable gold grain seeds are underway to improve the accuracy of radiotherapy using conformal or intensity modulated radiotherapy techniques. The Phase III trial of high dose hypofractionated radiotherapy testing the hypothesis that prostate cancer may have a low alpha-beta ratio is underway and has been supported by a Department of Health grant to the Prostate Cancer Collaborate to develop into a multicentre trial.
Metastatic Disease
Studies continue into the use of second- and third-line treatment approaches using hormones, chemotherapy, bisphosphonate drugs, novel agents such as the endothelin antagonist Atrasentan and bispecific antibody omnitarg as well as high dose isotope therapy in a compendium of national, institutional and commercially supported studies. Publication of the MRC PR05 study has documented the potential role of using the biphosphonate Clodronate as an adjuvant in metastatic disease which may prolong both disease free and overall survival (Dearnaley et al, JNCI 17.1300.2003).
Cancer Genetics and Laboratory Programme
UK studies into the genetic predisposition of prostate cancer, undertaken in collaboration with Cancer Research UK and the British Prostate Group, involve over 200 collaborating centres nationwide. The studies have expanded internationally. We lead a consortium (ACTANE) involved in the analysis of DNA samples from prostate cancer families in the UK (Anglo), Canada, Texas, Australia, Norway and European Union to find high-risk genes. We have confirmed that 2% of men with early onset prostate cancer harbour germ line mutations in the BRCA2 gene (Edwards et al Am.J. Hum.Genet 72(1).1.2003) but failed to show any relationship between leptin receptor polymorphisms and risk of young onset prostate cancer (Kote Jarai et al, BJU Int 92.109.2003). Epidemiological studies have started to try to identify interactions of genetic make up and environment. New techniques processing prostatectomy and transrectal guided biopsies are being developed to construct tissue microarrays. These will be used to assess putative markers of prostate cancer behaviour.

CLINICAL RESEARCH PROJECTS
Most clinical radiotherapy research is described under the individual Clinical Units in the Radiotherapy, Therapeutics, Breast and Haemato-oncology themes. We include here a description of the major research programme into novel techniques of conformal radiotherapy and intensity modulation (which are carried out jointly with the Department of Physics and are supported by a programme grant from Cancer Research UK). The more precise delivery of radiotherapy permits studies either to reduce radiation side-effects, or dose escalation to increase tumour control.
