It’s good to be busy, it can take your mind off stuff you don’t really want to think about. That was my tactic after being diagnosed with incurable Neuroendocrine Cancer. I just kept working and working and was still sending work emails and making telephone calls on the day I was being admitted to hospital for major surgery. After all, how could they possibly function without me? Although I was banned from work after the surgery, I still dropped an email to let them know I was doing cartwheels down the hospital corridor. They expected nothing less.
I guess the image of ‘invincibility’ was important to me at that time. It was part of my personal expectations and credibility. Some 6 weeks after leaving hospital following a 9 hour open surgery, I literally crawled back to the office, weak and drawn but determined to ‘make a statement’ by dint of my physical presence. A round of applause was given and for me this was as effective as any medicine I was taking. My credibility was intact.
Treatment, tests and consultations would now be managed around work instead of the other way – after all, they couldn’t possibly function without me? This ‘charade’ went on for some time until I eventually realised they could actually function without me and the only person expecting me to be ‘in service‘ on a treatment, testing or consultation day, was me. Additionally, it became patently obvious that people would totally understand my reasons for slowing down. However, a more serious message was being received from my body which was hinting it was more delicate than I had thought. My credibility, until hitherto sacrosanct, was taking its toll and things weren’t really back to normal. I began to realise I needed a different and better ‘normal‘.
After my ‘eureka’ moment, I totally changed my lifestyle putting my health above my credibility in the ‘pecking order’. I still keep busy – that’s important. I’m now happily doing things I enjoy at my own pace and my fatigue levels are now under control. Here’s my 5 top suggestions for prioritising your time and activities to be able to live with an incurable cancer.
- Reduce your stress. This is difficult with the modern life we now lead but if you can live without things that cause you stress – cease or drastically reduce their effect on you and boldness might be required to strike the right balance.
- Quality sleep. If your illness has a fatigue element, a decent night’s sleep becomes more important. Get into a routine if possible.
- Take time to exercise. It doesn’t need to be a marathon or a climb up Mt Everest. Even a regular short walk is enough and you can build up from there. This also helps with the sleep, fatigue and stress reduction.
- Learn to say no more often. This is difficult, particularly if you are the energetic multi-tasking go-getter type but your body has a voice – listen to it.
- Do more of the things you enjoy. We’re all guilty of procrastination from time to time but get more of the things you enjoy into your calendar, it supports all the other suggestions above!
I now have a new ‘normal’ and I feel healthier and more positive. I sometimes think I might be taking on too much leading to a return to the ‘old ways’. However, the big difference today is that I have no qualms about taking myself ‘out of service‘ or reducing my workload and commitments. My body tends to remind me now and then.
This is the second blog in the Neuroendocrine Cancer Nutrition series. In Blog 1, I focussed on Vitamin and Mineral deficiency risks for patients. Those who remember the content will have spotted the risks pertaining to the inability to absorb particular vitamins and minerals. This comes under the general heading of Malabsorption and in Neuroendocrine Cancer patients, this can be caused or exacerbated by one or more of a number of factors relating to their condition. It’s also worth pointing out that malabsorption issues can be caused by many other reasons unrelated to NETs. Additionally, malabsorption and nutrient deficiency issues can form part of the presentational symptoms which eventually lead to a diagnosis of Neuroendocrine Cancer; e.g. in my own case, I was initially diagnosed with Iron Deficiency Anaemia. Even after diagnosis, these issues still need to be carefully monitored as they can manifest as part of the consequences of having cancer and cancer treatment.
Malabsorption will present via several symptoms which may be similar to other issues (i.e. they could masquerade as, or worsen, the effect of a NET Syndrome). These symptoms may include (but are not limited to) tiredness/fatigue/lethargy, diarrhea, steatorrhea (see below), weight loss. Some of these symptoms could be a direct result of nutrient deficiencies caused by the malabsorption.
Crash Course……. We eat food, but our digestive system doesn’t absorb food, it absorbs nutrients. Food has to be broken down from things like steak and broccoli into its nutrient pieces: amino acids (from proteins), fatty acids and cholesterol (from fats), and simple sugars (from carbohydrates), as well as vitamins, minerals, and a variety of other plant and animal compounds. Digestive enzymes, primarily produced in the pancreas and small intestine (they’re also made in saliva glands and the stomach), break down our food into nutrients so that our bodies can absorb them. If we don’t have enough digestive enzymes, we can’t break down our food—which means even though we’re eating well, we aren’t absorbing all that good nutrition.
The malabsorption associated with Neuroendocrine Cancer is most prevalent with the inability to digest fat properly which can lead to steatorrhea. Patients will recognise this in their stools. They may be floating, foul-smelling and greasy (oily) and frothy looking. Whilst we all need some fat in our diets (e.g. for energy), if a patient is not absorbing fat, it ends up being wasted in their stools and in addition to the steatorrhea, it can also potentially lead to (unwanted) weight loss and micronutrient deficiencies of the fat-soluble vitamins A, D, E and K. Certain water-soluble vitamins, particularly B3 and B12, are also at risk. Steatorrhea issues can be addressed by prescribing enzyme replacement therapy (PERT) products as directed by your doctors or dietician (e.g. Creon etc).
Structoral Changes (i.e. Surgery) can play a big part in malabsorption issues. For example, if a patient has undergone Pancreatic surgery, this will most likely effect the availability of pancreatic digestive enzymes needed to break down food. Many Small Intestine NET (SINET) patients will suffer due to the removal of sections of their ileum, an area where absorption of water-soluble vitamins and other nutrients take place. In fact, the terminal ileum is really the only place where B12 is efficiently absorbed. Although a less common tumour location, jejunum surgery could result in loss of nutrients as this section of the small intestine is active in digestive processes. Malabsorption issues for SINETs are an added complication to the issues caused by a shorter bowel (e.g. increased transit times), something which is regularly assumed to be the effects of one of the NET Syndromes.
Another risk created by the lack of terminal ileum is Bile Acids Malabsorption (BAM) (sometimes known as Bile Salts Malabsorption). Bile Acids are produced in the liver and have major roles in the absorption of lipids in the small intestine. Following a terminal ileum resection which includes a right hemicolectomy, there is a risk that excess Bile Acids will leak into the large intestine (colon) via the anastomosis (the new joint between small and large intestines). This leakage can lead to increased motility, shortening the colonic transit time, and so producing watery diarrhoea (or exacerbating an existing condition). Although this condition can be treated using bile acid sequestrants, it is difficult to pinpoint it as the cause.
The Gallbladder plays an important part in the digestive system – particularly in fat breakdown. The liver continually manufactures bile, which travels to the gallbladder where it is stored and concentrated. Bile helps to digest fat and the gallbladder automatically secretes a lot of bile into the small intestine after a fatty meal. However, when the gallbladder is removed, the storage of bile is no longer possible and to a certain extent, neither is the ‘on demand automation’. This results in the bile being constantly delivered/trickled into the small intestine making the digestion of fat less efficient. One of the key side effects of Somatostatin Analogues (Octreotide and Lanreotide) is the formation of gall stones and many Neuroendocrine Cancer patients have their gallbladder removed to offset the risk of succumbing to these issues downstream. Removal of the gallbladder also increases the risk of BAM as described above. Any issues with Bile Ducts can also have a similar effect.
The Liver has multiple functions including the production of bile as stated above. However, one of its key functions within the digestive system is to process the nutrients absorbed from the small intestine. If this process is affected by disease, it can potentially worsen the issues outlined above.
Somatostatin Analogues can also impact (or worsen) the ability to digest fat as they inhibit the production of pancreatic digestive enzymes. This is a well-known side effect of both Octreotide and Lanreotide.
The levels of the fat-soluble vitamins (ADEK) and B vitamins such as B12, need to be monitored through testing and/or in reaction to symptoms of malabsorption. If necessary these issues need to be offset with the use of supplements as directed by your dietician or doctor. Supplements are less affected by malabsorption of nutrients but their efficiency can be impacted by fast gut transit times (thus why testing is important). The evidence is here: Click Here.
Deficiencies of these vitamins and certain minerals can lead to other conditions/comorbidities, some more serious than others. For a list of the vitamins and minerals most at risk for Neuroendocrine Cancer patients, have a read of my blog – Vitamin and Mineral deficiency risks.
There is a third blog in this series discussing a related issue with Neuroendocrine Cancer, particularly where gut surgery has been performed. You can link directly to this blog here – “Gut Health” – (Gut Health, Probiotics and Small Intestinal Bacterial Overgrowth (SIBO)).
Blog 4 looks at Amines and why they can cause food reactions or exacerbate syndromes.
Again, I remain very grateful to Tara Whyand for some assistance. This is a big and complex subject and I only intended to cover the basics. If you need professional advice, you should speak to your doctor or dietician.
