Muscle invasive bladder cancer is the sixth most common cancer and remains a major cause of death and suffering worldwide. The standard treatment for advanced bladder cancer has been surgical removal of the bladder (cystectomy) which is associated with considerable morbidity. Many (20%) patients are elderly, with significant co-morbidities and hence are high risk for a major operation. In the past patients who were not able to undergo surgery were offered palliative radiotherapy. Research at the University of Birmingham has shown that the addition of low toxicity chemotherapy to radiotherapy is as effective as cystectomy in controlling disease progression and has minimal impact on bladder function. This new approach is an excellent alternative to cystectomy and has been adopted as a new standard of care thus demonstrating considerable impact on clinical practice and patient outcome.
University of Glasgow research has led to the adoption of first-line chemotherapy for ovarian cancer, which has improved patient survival by 11% and has been used to treat 66% of women with ovarian cancer since January 2011 in the West of Scotland Cancer Care Network alone. These therapies are recommended by guidelines for ovarian cancer treatment in the USA, Europe and the UK. The USA guidelines are disseminated to 4.3 million people worldwide and the European guidelines reach 15,000 health professionals. The UK guidelines are used to identify those drugs that are funded by the NHS and used in NHS hospitals.
The MRC Conventional versus Laparoscopic-Assisted Surgery In Colorectal Cancer trial (CLASICC) is the largest and most successful UK trial of a technology applied to general surgery. It addressed an area of huge clinical uncertainty, providing a rigorous evaluation of a new technology and enabling its safe and widespread implementation. The impact of CLASICC has been global, confirming the advantages for patients (quicker recovery) and healthcare providers (cost-effectiveness) and so influencing national and international policy in favour of the laparoscopic technique. It informed NICE guidance and led to a major DH initiative that has seen the UK become one of the largest providers in the world of laparoscopic colorectal cancer surgery. CLASICC is regarded as a benchmark surgical trial, combining high quality trial design with rigorous quality assurance, which has informed the design of many subsequent colorectal cancer studies.
Colorectal cancer is a common disease, which frequently causes death or morbidity, either because of failure to control the primary tumour or failure to prevent distant metastases. Leeds researchers have devised new treatment approaches using chemotherapy and radiotherapy and tested them in large randomised controlled trials which have led to major changes in clinical practice in the management of rectal cancer and advanced colorectal cancer (aCRC), driving clinical decision-making and improving outcomes for patients. This includes better-evidenced treatment for elderly patients and patient stratification on the basis of molecular biomarkers.
Before 2010, there was no accepted standard treatment for patients with advanced biliary tract cancer. The ABC02 trial showed that the combination of two drugs (gemcitabine and cisplatin) significantly improves survival, with acceptable side effects. Consequently, national and international guidelines have been revised to recommend this regimen as a standard of care. Furthermore, in ongoing trials of novel therapies, gemcitabine/cisplatin has become the comparator group, and the aim is to improve survival above what this can already achieve.
UCL has conducted a series of national lung cancer trials, which have led to wide-scale changes in clinical practice. Two trials compared different platinum based therapies, which led to centres switching from using chemotherapy with cisplatin to carboplatin-based chemotherapy instead. Carboplatin can be given as an outpatient, and has fewer side effects, and has been (and still is) recommended as an alternative to cisplatin in the UK and US.
The HiLo trial has changed management for patients with well-differentiated thyroid cancer. Patients undergoing radioiodine ablation therapy are now given a low dose of radioactive iodine, which has fewer side effects, compared to the previous (standard) high dose. Also, to prepare patients for ablation they now have recombinant human TSH (thyrotropin alfa), which is associated with a better quality of life before and during ablation. The combination of low dose radioiodine and thyrotropin alfa means that patients can be treated as outpatients rather than inpatients. This is a more convenient treatment package, reducing health service and societal costs.
Bowel cancer is the third most frequently diagnosed cancer worldwide. University of Glasgow researchers have established Xeloda (an oral 5-fluorouracil precursor) and XELOX (a chemotherapeutic regimen combining Xeloda with oxaliplatin) as highly effective, targeted therapies for patients with bowel cancer. Since 2008, European regulatory approval of these therapies has been incorporated into major international clinical guidelines. The research has transformed patient care by improving the treatment experience, with more convenient dosing schedules and fewer side effects compared with previous chemotherapy procedures. Xeloda and XELOX have transformed chemotherapy for bowel cancer and decreased therapeutic costs, potentially saving around £4,762 (Xeloda) and £947 (XELOX) per patient for the NHS.
Collaborative research conducted by the Biological Sciences Research Group (BSRG) has brought considerable benefits for the treatment of cancer patients. Experimental research has shown that the shelf-life of the biological cancer drug Herceptin can be greatly extended thereby bringing significant economic benefit through cost savings. A clinical trial has demonstrated that yoga benefits the health and well-being of patients with gynaecological cancer leading to prospects of improved cancer survivorship. Sowter provides research-informed oncology training for NHS clinical trials staff throughout the National Institute of Cancer Research UK network (NCRN), and has supervised two senior registrars through their MD qualifications.
Impact: Health and welfare; additional effective therapy for women with advanced, HER2+ breast cancer.
Significance: Allows approximately 10,000 patients a year, whose disease is no longer being controlled by trastuzumab, to receive a more effective therapy than chemotherapy with capecitabine alone.
Beneficiaries: Patients with incurable metastatic HER2+ subtype breast cancer; policy-makers; commerce.
Attribution: Cameron (UoE) was joint chief-investigator on the global pivotal registration trial that led to the marketing authorisation of the drug lapatinib in combination with capecitabine.
Reach: World-wide: the drug is approved in >100 countries and generated >£650M in sales for manufacturer GlaxoSmithKline.
