Calidad de vida en pacientes con cáncer de esófago y de estómago
Calidad de vida en pacientes con cáncer de esófago y de estómago
Publicado en Cir Esp. 2011;89:635-44. - vol.89 núm 10
Resumen
El estudio de la calidad de vida relacionada con la salud en pacientes con cáncer digestivo y, de modo especial, en aquellos con tumores del esófago y del estómago, proporciona una información útil para seleccionar la opción terapéutica más adecuada y, asimismo, predecir el impacto de la enfermedad y, de sus posibles tratamientos, sobre la condición física, emocional y social del paciente.
En las últimas décadas se han desarrollado y validado diversos instrumentos que miden la calidad de vida de los pacientes de forma sensible y fiable; la utilización de cuestionarios ha facilitado el intercambio de esta valiosa información entre el paciente y el médico. Las variaciones pre y postoperatorias de la calidad de vida en pacientes con cáncer esófago-gástrico poseen valor pronóstico sobre la evolución de la enfermedad.
Por todas estas razones, la calidad de vida relacionada con la salud se considera hoy en día, junto con la supervivencia libre de enfermedad y la ausencia de recidivas, uno de los parámetros más importantes para poder evaluar el impacto de un determinado tratamiento oncológico sobre los pacientes.
El propósito de este artículo es revisar el papel de la valoración de la calidad de vida relacionada con la salud, así como los diversos instrumentos de los que se dispone para medirla, en los pacientes con cáncer esófago-gástrico.

The causes of cancer you can control
Can cancer be prevented? Decades of research have shown that a person’s chances of getting cancer depends on a mishmash of their genes and their environment, but also certain aspects of their lives, many of which they can control.
Today saw the publication of a landmark Cancer Research UK-funded review by Professor Max Parkin, outlining the latest evidence behind the preventable causes of UK cancers.
As our press release says, these latest calculations, based on predicted cases for 2010, show that smoking, diet, alcohol and obesity are behind more than 100,000 cancers. This is equivalent to one third of all cancers diagnosed in the UK each year.
And this figure further increases to around 134,000 when taking into account all 14 lifestyle and environmental risk factors analysed in this study.
There’s more in-depth information about the statistics on our website, and our healthy living pages explain the take-home messages from the research.
But to help make sense of the vast quantity of information contained in the 91-page report, we’ve also put together a graphic that shows the proportion of cancers that can be prevented through lifestyle changes. It’s worth spending a minute or so looking at the key to understand how to interpret the graphic (which you can download as a larger PDF version).
Information is power
Providing this type of information is categorically not about blame – every two minutessomeone in the UK is diagnosed with cancer, and each of them have a unique set of circumstances that led to their cancer. There are many things that together affect a person’s chances of developing cancer – some of them can be controlled, some can’t.
Leading a healthy lifestyle is not a cast-iron guarantee against cancer. But it reduces the risk of the disease. If you think about cancer risk like a hand of cards, some people are dealt a worse hand because of their genes, some people a better one.
But in both cases, these people can do things to reduce their individual risk of cancer. So this type of information is crucial in equipping people with the information they need to stack the odds in their favour.
Such information is also crucial to guide policymakers in planning public health interventions. For instance, decades of work documenting the risks of smoking tobacco and the benefits of giving up – much of it by our scientists – has contributed to increased acceptance of tobacco as a major health hazard and led to many successful tobacco control measures.
We’re now starting to see the effects of these policies in lung cancer rates amongst UK men. But there’s more work still to do.
Bah humbug?
We’re also aware of the irony of publishing this research just before Christmas, when many of us enjoy one too many mince pies, or a few too many glasses of mulled wine. In our press release, we explain that we’re not expecting everyone to watch what they eat and limit alcohol intake during the festive season, and we don’t want people to feel guilty about indulging a bit more than usual.
Rather than focus on short-term behaviour changes, healthy living is about long-term lifestyle tweaks that can really make a difference. Regularly taking the stairs rather than using the lift, drinking a couple fewer beers or wines every week, eating a little more fruit, etc.
Incorporating a series of such healthy behaviours into your daily life can make a significant difference to your future risk of cancer.
What you need to know
Finally, below we’ve pulled together some of the important information you need to know about the 14 lifestyle and environmental risk factors analysed in this study:
- Tobacco – although the number of smokers has fallen dramatically over the last 30 years, and lung cancer rates have fallen too, UK smoking rates have stagnated over recent years at around 22 per cent. We’re doing all we can to help people quit and protect children from the influences that lead them to become smokers. That’s why we’re campaigning for plain packaging – so that young children won’t be exposed to the tobacco industry’s last marketing channel.
- Overweight – obesity and being overweight was the second biggest cause of cancer in the UK in the new study. Despite this, people are still unaware that their weight can have such a strong influence on their cancer risk. In a Cancer Research UK survey, only 3 per cent of people named obesity as something that can increase cancer risk. We’re using campaigns like Active Fat to help people understand that keeping a healthy weight can really help reduce the risk.
- Fruit and vegetables – the reason fruit and veg come out so highly in this analysis is probably that many people in the UK eat fewer than their recommended 5 portions a day. Fruit and veg are an important source of vitamins, minerals and fibre, but don’t rely on supplements to get the nutrients you need – they haven’t been shown to reduce cancer risk and, in some cases, they may be harmful.
- Alcohol - you don’t have to cut out alcohol completely to reduce the risk of cancer – the more you cut down, the more you can reduce the risk. You could try tracking your drinking for a few weeks, to see how much alcohol you really drink – many people underestimate the amount. Use our drinks tracker or download the NHS app on your iPhone or android device.
- Occupation – some people are more at risk of cancer as a result of chemicals or practices used in their occupations. But improved safety in the workplace means fewer people will be at risk now than in the past. If you’re concerned about your work environment, talk to your managers or you could contact the Health and Safety Executive.
- Sunlight and sunbeds – getting too much exposure to UV light, whether from the sun or sunbeds, is the main cause of skin cancers. And rates of malignant melanoma, the most serious form of skin cancer, are rising fast. Cancer Research UK runs SunSmart, a national skin cancer prevention campaign, to help people know what they can do to reduce the risk of sunburn and skin cancers. At the moment, we’re running ‘R UV UGLY?’, which offers sunbed users the chance to see what’s really going on in their skin. Find out more and take part on our facebook page.
- Infections – in the UK, human papillomavirus, or HPV, is behind the most cancers, followed by Helicobacter pylori, which causes stomach cancer. Girls aged 12-13 are now vaccinated against the two most common cancer-causing types of HPV, which means rates of cervical cancer should decline substantially in the near future
- Red and processed meat – red meat is any fresh, minced or frozen beef, pork, lamb or veal. And processed meat means anything that’s been preserved (apart from by freezing) – so it includes salami, bacon, ham and sausages. Eating small amounts of these meats won’t have a huge effect on cancer risk, but it’s a good idea to limit your intake to only a couple of times a week. Here’s a post from our archives about how red meat might increase the risk of bowel cancer.
- Radiation – we’re all exposed to natural background radiation all the time, from the earth and from space. And occasionally we are exposed to higher doses, such as from X-rays, radiotherapy or travelling by aeroplane.
- Fibre – eating a high-fibre diet can reduce the risk of bowel cancer – it helps speed up food passing through the digestive system, and dilutes waste food, so that cancer-causing chemicals in our food aren’t in contact with the bowel wall for so long.
- Physical activity – being active not only helps you keep a healthy weight, but also reduces cancer risk by itself. But you don’t have to slog it out in the gym for hours a day – just 30 minutes of moderate activity on 5 days a week gives you the benefit. And even small bits of activity throughout the day add up.
- Not breast feeding – breast feeding babies has been shown to reduce the risk of breast cancer – so if you’re able to, and not everyone is, it’s a good idea to try to keep it up for 6 months.
- Salt – high-salt diets can increase the risk of stomach cancer, but other factors like the common bacterial infection Helicobacter pylori and smoking also play an important role.
- Hormone replacement therapy – HRT is an effective treatment for menopausal symptoms, but it can increase the risk of cancer. If you’re considering starting or stopping HRT, it’s a good idea to talk to your doctor first.
