Cancer: An Epidemy Potency

Nutritional Problem
Among Cancer Patients
Weight loss and malnutrition are one of most common features observed in cancer patients
Cancer associated malnutrition 40-80%
IndonesiaSurvey in Dharmais Hospital, 2008
30.9% has malnutrition
42.9% reported weight loss in 6 mo.

Malnutrition vs Cachexia
Cancer
Cancer cachexia Malnutrition (Undernutrition)
Malnutrition a state of nutrition in which a
imbalance of energy, protein, and other nutrients
causes measurable adverse effects on
tissue/body form (body shape, size and
composition) and function, and clinical outcome
Muscaritoli M et al. Clin Nutr 2010;29:154–9

Cachexia Cancer
Definition of cachexia:1
Complex metabolic syndrome associated with underlying illness and characterized by loss of muscle with/without loss of fat mass
Definition of Cachexia Cancer:2
Multi organ syndrome charactrized by:
Weight loss (at least 5%)
during the previous 3-6 mo.
Muscle and adipose wasting
Inflammation
often associated with ANOREXIA, include
the abnormalities of metabolism

Nutritional Consequences Of
Cancer Therapy
Mechanism:
a. Directly interfere with metabolism
b. Indirectly affect nutrient intake (nausea,
vomiting, diarrhea, changes in taste
sensation, anorexia & food aversions)

Side Effect of
Radiotherapy
Early effect the most common, can be
anticipated and limited duration.
Severity of side effect depends on: type of
irradiation, body region, volume of irradiation
and combination with other therapy
(chemotheray).

Decrease weight loss, promote weight gain, and increase survival in cancer cachexia patients
May activate caspase-3 apoptosis
May inhibit COX-2 reducing inflammatory process
In cancer cachexia patients, EPA significantly reduce the serum concentration of CRP (marker of inflammation)

loss appetite, dry mouth, nausea-vomiting,
swallow difficulties, taste/smell alteration
Oral Nutrition
![Page 40: Nutrition for Patients during Radiotherapy in Nasopharyngeal Cancer](https://reader036.fdocuments.in/reader036/viewer/2022081400/5475c0f5b4af9fb40a8b5dcc/html5/thumbnails/40.jpg)
Frequent small meals
Increase caloric and protein density of foods,
avoid excessive fat
Avoid strong odors
Select soft, moise foods; add sauce/gravy
Limit liquids at mealtime
Provide a pleasant mealtime atmosphere
Oral Nutrition
![Page 41: Nutrition for Patients during Radiotherapy in Nasopharyngeal Cancer](https://reader036.fdocuments.in/reader036/viewer/2022081400/5475c0f5b4af9fb40a8b5dcc/html5/thumbnails/41.jpg)
Enteral nutrition
If oral intake is not adequate
Preferred to parenteralpreserves the gastrointestinal architecture & prevents bacterial translocation fewer complication
Type•Short term:

Enteral Nutrition
Tube feeding:
obstruction of head or neck or esophageal
cancer interferes with swallowing
Severe local mucositis
percutaneous gastrostomy (PEG):
radiation induced oral and esophageal
mucositis
![Page 43: Nutrition for Patients during Radiotherapy in Nasopharyngeal Cancer](https://reader036.fdocuments.in/reader036/viewer/2022081400/5475c0f5b4af9fb40a8b5dcc/html5/thumbnails/43.jpg)
Routine enteral nutrition is not indicated during radiation
Therapy or chemotherapy as long as food intake is adequate
by oral
Enteral Nutrition
Recommendation
Enteral nutrition if an inadequate food intake (<
60% of estimated energy expenditure for > 10
days) is anticipated (C)
Enteral nutrition should be provided to improve
or maintain nutritional status in weight losing
patients due to insufficient nutritional intake (B)
![Page 44: Nutrition for Patients during Radiotherapy in Nasopharyngeal Cancer](https://reader036.fdocuments.in/reader036/viewer/2022081400/5475c0f5b4af9fb40a8b5dcc/html5/thumbnails/44.jpg)

Possible causes : mucositis radiation and/or chemotherapy
• Mucositis cancer treatments break down the rapidly divided epithelial cells lining the GIT particularly in oral cavity, leaving the mucosal tissue open to ulceration and infection
• Oral mucositis the most common
20-40%chemotherapy alone
> 50% combination (chemo-radiotherapy)
consequences : hypovolemia, electrolyte abnormalities & malnutrition
Sore mouth / throat
![Page 48: Nutrition for Patients during Radiotherapy in Nasopharyngeal Cancer](https://reader036.fdocuments.in/reader036/viewer/2022081400/5475c0f5b4af9fb40a8b5dcc/html5/thumbnails/48.jpg)
Mucositis should be treated as early as possible
Adequate education on proper nutrition and oral
hygiene is essential
Management
- Give intensive mouth care to prevent bacterial infection or mouth lesions
- Eat soft, bland foods
- Try eating cold, odorless foods
- Avoid eating too hot or cold food
- Drink through a straw to bypass mouth sores
- Avoid irritating spices such as pepper, chili
- Eat high-protein foods to speed healing
Sore mouth / throat

Management (continue)
• Drink high-calorie liquid nutritional supplements to help maintain adequate calorie intake
• Avoid alcohol, tobacco irritate mucous membranes
• Begin use of tube feedings
• Puree / liquefy food in blender easier to swallow
