Perspectives Profile Alan Craft: a trailblazer in paediatric oncology It was quite by accident that Alan Craft ended up being such a key figure in paediatric oncology. When a colleague at Newcastle’s Royal Victoria Infirmary went on maternity leave in the 1970s, he stood in to look after children with leukaemia. This became Craft’s chosen field, and over four subsequent decades his reward has been the pleasure of seeing huge increases in survival rates for childhood cancer. Craft has spent most of his life in Newcastle, the largest city in the UK’s northeast, attending school and university there. Like many great doctors and researchers, an inspiring science teacher—in his case a biology teacher—steered him towards medicine and a place at Newcastle University Medical School. That turned out to be the right decision: “It was during my final year of medicine working with a wonderful physician in Carlisle that all I had learned came together, and I realised what medicine was all about”, Craft told The Lancet. So he took a position at Newcastle’s Royal Victoria Infirmary as a paediatrician. It was the early 1970s, and treatments for leukaemia were just becoming available but most children were still dying. While caring for children with the disease, Craft discovered a passion for oncology and trained as a paediatric oncologist. After a year at London’s Royal Marsden Hospital, he returned to Newcastle to set up the hospital’s first ever paediatric oncology unit. “Back then, our motto was cure at any cost”, recalls Craft, “But today it’s cure at least cost—and modern drugs and better supportive care mean that children are better able to cope with the side effects of treatment.” He has also seen a striking increase in survival for many childhood cancers: “for leukaemia survival rates have increased from some 30% to around 85% during my working lifetime”, he says. Throughout that working life, Craft has developed an interest in epidemiology, which has been as much about finding out what causes cancer as curing it. “One of the important insights Alan had, which certainly had a great impact on my career, was to recognise the importance of epidemiology in identifying the antecedents of childhood cancer”, says Louise Parker, who began working for Craft’s research team in 1987 and went on to become a leading scientist in this field. Craft and Parker’s base in Newcastle proved to be important. “Children came to our unit from most of northern England, including nearby Cumbria, home to the Sellafield nuclear reprocessing plant and the site of a major cluster of leukaemia”, explains Craft. Parker and Craft set about trying to understand these patients. They were joined by Mark Pearce, who completed a PhD on a study of the workers at Sellafield, which showed an increased risk of leukaemia and stillbirth with a dose dependent relation. Previous work on radiation and guidance on radiation protection had come from studies of the atomic bomb www.thelancet.com Vol 380 August 4, 2012 survivors in Japan, but these were based on rather imprecise measurements. Craft, Pearce, and Parker, along with colleagues from the US National Cancer Institute, decided to investigate whether radiation exposure from CT scans might be associated with the development of cancer. The study they publish in The Lancet is the culmination of many years’ work checking through hospital data from 70% of the UK’s hospitals and some 175 000 patients. “We can now confirm the Japanese data and put radiation protection on a much firmer basis. While CT scans can be hugely beneficial, for diagnosing serious brain injury and other problems, there is a risk-benefit ratio. Use of this technology to diagnose more minor ailments or conditions such as appendicitis, as described in recent research, could be exposing patients to an unacceptable increased risk of leukaemia or brain cancer”, Craft says. In a sense, this study marks the conclusion of a remarkable career; Craft retired in 2010 and retains an emeritus chair at Newcastle University. His services to paediatric oncology saw him receive a knighthood in 2004—an honour that Parker, who now works at Dalhousie University and for the Canadian Cancer Society, thinks is richly deserved: “Alan has been my colleague and great friend for 25 years. Through each of those 25 years his commitment to bettering the health of children everywhere has been unwavering through his clinical practice and leadership in research and clinical medicine.” William Woods, of Emory University and the Aflac Cancer and Blood Disorders Center, concurs. “He helped to organise the UK Children’s Cancer Study Group over 30 years ago, leading studies in bone tumours for the Group as well as in the International Society of Paediatric Oncology; and later becoming its President. In the process Alan directed the childhood cancer programme at the Royal Victoria Infirmary in Newcastle, building one of the pre-eminent programmes in the UK.” In retirement, Craft retains an active interest in research. But he now has time for other interests: Craft is Chairman of the UK Scout Association and has been selected to carry the Olympic Torch ahead of London’s summer Olympic Games. Yet there are still many questions Craft would like to see answered. “The work we have done on CT scans needs to be extended, and there are advanced plans to expand our study into Europe”, he says. “The effects of CT scans in older people should also be investigated, although they could be expected to be less sensitive to radiation.” However, Craft’s passion for his retirement pursuits mean that these questions will be answered by the next generation of researchers.
