Comment and opinion from Cancer Research UK\u2019s community of experts. The opinions outlined in this article do not necessarily represent the views of Cancer Research UK.<\/em><\/strong><\/p>

The original cancer problem was that we weren\u2019t testing smartly enough. When I became a GP over 30 years ago, we didn\u2019t know well enough who of those walking through the doors to our GP surgeries could be harbouring cancer, so the big push was to be better at identifying the different levels of cancer risk associated with different symptoms and test results to inform who needed testing and who didn\u2019t.<\/p>

It feels like we\u2019ve got there now \u2013 the guidance<\/a> issued by the National Institute of Health and Care Excellence (NICE) in 2015 was the high citadel of testing smarter: the previous guidance in 2005 simply not having enough evidence behind its recommendations. The other paradigm-shifting in 2015 was the decision to give an explicit risk of cancer that warranted urgent testing \u2013 and in being ambitious in setting it as low as 3%. Even more liberal was encouraging GP testing at lower risks than 3%.<\/p>\n

But if we stick to the 3% rule outlined in the NICE guidance \u2013 that you urgently refer or do tests only if someone\u2019s symptoms equate to a 3% risk of cancer or greater, there will be some people that will never get testing and will end up presenting as an emergency. We will only be able to capture those people if we\u2019re prepared to test more. We can only test more if we make it patient friendly and economically friendly. Both of those factors point towards stationing it closer to the patient \u2013 in general practice or on the high street.<\/p>\n

This won\u2019t work for all presentations I hasten to add \u2013 GPs will still need to refer patients to hospital for some tests. We don\u2019t have the technology in primary care to do the tests for a woman with a breast lump, for example, so we need to get the experts involved. But there are many other cancers where you can move towards more testing outside of hospitals. Things like chest X-rays, blood counts, platelet counts, but also more sophisticated tests like CA125 or ultrasound to pick up potential ovarian cancer and in the future potentially blood tests that pick up cell-free DNA.<\/p>\n

GPs are evolving<\/h2>\n

It\u2019s a win-win. From a patient perspective \u2013 the closer to home you can do tests, the easier, more familiar, and hopefully nicer, it will be. It\u2019s also likely to be cheaper, and you may get your results back quicker \u2013 because at least you\u2019ve got your GP\u2019s phone number.<\/p>\n

The question is \u2013 are we blurring the line by moving more testing to primary care or community settings such as community diagnostic hubs recently recommended in Professor Sir Mike Richards\u2019 review of diagnostic services? Some GPs may say yes, some specialists may say yes. It\u2019s never going to be a unanimous decision \u2013 there are 40,000 GPs in the UK with I would imagine around 40,000 different opinions on the best way to deliver care.<\/p>\n

But I would argue that the line has been blurring for years. Stretching the limits of primary care is a part of its history. The truth is primary care evolves, GP practices evolve. In time, practices that were inconceivable become the norm.<\/p>\n

Take Faecal Immunochemical Testing (FIT)<\/a>. It was used only as part of bowel screening, but a few years ago NICE brought it in to test people who had low-risk symptoms below the threshold for referral for a colonoscopy<\/a> for suspected bowel cancer, but where something might be going on that needed investigating. It wasn\u2019t a popular decision at first \u2013 there was tremendous fear within the surgical community that using FIT in people with such symptoms would lead to an influx of patients without disease, which would overwhelm endoscopy services.<\/p>\n

But the doomsayers missed two points that have turned out to be true. The first was, if someone had a positive FIT, they were no longer low risk, they became quite high risk \u2013 11% of people who tested positive went on to be diagnosed with bowel cancer. The other point was they were lowering their threshold for testing anyway: \u2018low-risk\u2019 patients were being offered colonoscopies. Fair enough, as there was no other test. So bringing in FIT as a way of sifting in primary care actually reduced pressure on endoscopy services.<\/p>\n

The icing on the cake<\/h2>\n

There are so many reasons why increasing testing is smart. Firstly, patients want it \u2013 if cancer is even a remote possibility people want to know. The other thing is, general practice is not simply painting by numbers. I don\u2019t particularly like the phrase \u2018gut feeling\u2019, though intuition is a bit better. It\u2019s experience: let\u2019s call it the icing on the cake \u2013 the experience that helps a GP see something unusual, the classical \u2018needle in the haystack\u2019. Giving GPs more flexibility with how they can test will mean they can more easily navigate patients through the complex health system we have.<\/p>\n

But can the NHS cope? We know the NHS is stretched \u2013 and cancer is an area where specialists are living with limitations to the number of personnel and equipment they have available. But as we\u2019ve seen a number of times, moving testing into a community setting \u2013 be that in GP practices or future community diagnostic hubs \u2013 can help alleviate pressure by helping to identify people who do need further tests or treatment.<\/p>\n

And when it comes to GPs, I think we can handle it. I\u2019m not saying we need to test everyone who comes through the door \u2013 we are experts in managing risk. I\u2019m talking about one or two patients a week that warrant a more liberal approach to testing, you do a test and then if it\u2019s positive, you refer them on. That\u2019s not rocket science.<\/p>\n

Of course, with more testing we may find more things that aren\u2019t cancer, which could contribute to increased anxiety and more demand on the health service. But if we are to shift outcomes for cancer the way UK Government says it wants to, we have to be proactive and go looking for cancer, not wait for it to come to us. By that time, it could be too late.<\/p>\n

And now may be the perfect time. Before COVID-19, general practice was struggling to provide the highest quality care that we want to offer. My colleagues were sinking in a pile of paperwork, but also in their own successes \u2013 we\u2019re keeping people in the UK alive for longer, and that means more people to see and more conditions to treat and manage.<\/p>\n

It\u2019s a strange thing to say, but COVID-19 might have saved general practice. It forced us to redesign and take stock. The wholesale switch to remote consulting has shown us that there are ways of dealing with patients\u2019 problems that are acceptable. There\u2019s a lot of debate around that and how we\u2019ll work in the future, but I think it\u2019s safe to say that we\u2019ll never 100% switch back.<\/p>\n

As always, we\u2019re evolving \u2013 and a shift towards increased testing to further drive improvements in outcomes for patients should be a part of that.<\/p>\n
