What is Nutrition Care for Cancer Patients?

Malnutrition affects 30-80% of cancer patients depending on tumor type, stage, and treatment, with highest prevalence in upper gastrointestinal, head and neck, lung, and pancreatic cancers. Cancer cachexia, a hypercatabolic syndrome with weight loss, muscle wasting, and inflammation, is distinct from simple starvation and predicts worse outcomes including treatment toxicity, hospitalization, and mortality.

Nutrition assessment combines validated screening tools (NRS-2002, MUST, PG-SGA) with anthropometry, body composition (CT muscle area, BIA), and laboratory markers. Energy needs are typically 25-30 kcal/kg/day with protein 1.0-1.5 g/kg/day, individualized for treatment phase, performance status, and comorbidities. Sarcopenia identification through imaging guides intensified intervention.

Nutrition therapy follows a tiered approach: oral nutrition first with food fortification and counseling, then oral nutritional supplements (ONS), enteral nutrition for inadequate intake or dysphagia, and parenteral nutrition for nonfunctional gut. Multimodal interventions adding exercise (resistance and aerobic) and pharmacotherapy (anamorelin, megestrol) are emerging for cancer cachexia.

Symptoms

Unintentional weight loss (more than 5% in 3 months)
Reduced appetite, early satiety
Taste and smell alterations from treatment
Nausea, vomiting, diarrhea, mucositis
Difficulty chewing or swallowing (dysphagia)
Fatigue and reduced functional status
Muscle wasting and weakness
Subcutaneous fat loss
Edema or fluid shifts (hypoalbuminemia)
Decreased grip strength
Treatment delays or dose reductions due to weight loss
Pressure sores
Reduced wound healing

Risk Factors

Upper GI, head and neck, lung, pancreatic cancers
Advanced disease stage
Chemotherapy or radiation toxicity to GI tract
Surgical resection of digestive organs
Pre-existing comorbidities (diabetes, heart failure, renal disease)
Older age and frailty
Limited social support and food insecurity
Depression and anxiety
Polypharmacy with appetite-suppressing medications
Prolonged hospitalization

When to See a Doctor?

If you experience any of the following symptoms, seek medical attention promptly:

  • Weight loss 5% or more in 3 months
  • Inability to eat or drink for more than 5 days
  • Persistent vomiting or diarrhea
  • Severe mucositis preventing intake
  • Dysphagia after head and neck or esophageal treatment
  • Refusal of food and progressive weakness
  • Treatment delays due to nutritional decline
  • Need for tube feeding or parenteral nutrition consideration
  • Symptoms of refeeding (after long anorexia period)
  • Caregiver concerns about meal preparation

Treatment Methods

01
Routine nutrition screening at diagnosis and throughout treatment (NRS-2002, MUST)
02
Comprehensive assessment by registered dietitian (PG-SGA, anthropometry, intake)
03
Body composition: CT muscle area, BIA, grip strength
04
Calculate energy needs 25-30 kcal/kg/day, protein 1.0-1.5 g/kg/day
05
Individualized counseling on food fortification and small frequent meals
06
Manage symptoms: antiemetics, prokinetics, oral care for mucositis, taste modifiers
07
Oral nutritional supplements (ONS) when intake less than 60% of needs
08
Specialized formulas: high-protein, EPA-enriched, immune-modulating
09
Enteral nutrition: nasogastric, gastrostomy, or jejunostomy for prolonged inadequate intake
10
Prophylactic gastrostomy in head and neck radiation high-risk groups
11
Parenteral nutrition only when gut nonfunctional or perioperative
12
Refeeding syndrome prevention: gradual increase, electrolyte and thiamine supplementation
13
Resistance and aerobic exercise programs
14
Cancer cachexia: anamorelin (where available), low-dose corticosteroids short term, megestrol acetate (with VTE caution)
15
Manage hyperglycemia in steroid-treated or pancreatic cancer patients
16
Nutrition support during stem cell transplant and ICU stays
17
Hydration assessment and oral or IV fluids
18
Probiotics and fiber adjusted to treatment phase
19
Survivorship nutrition: weight management, plant-forward diet, alcohol moderation
20
Multidisciplinary team with dietitians, physicians, nurses, speech therapists, pharmacists

Anaemia

Dahiliye (İç Hastalıkları)

Anaemia is a low haemoglobin level that reduces oxygen delivery, causing fatigue, pallor, and shortness of breath. It is not a disease itself but a sign of many underlying conditions. Most cases are correctable with appropriate diagnosis and treatment.

Iron Deficiency Anaemia

Dahiliye (İç Hastalıkları)

Iron deficiency anaemia develops when dietary intake, absorption, or losses create an iron shortfall, most often affecting women and children. Identifying the underlying cause is the core of management, alongside iron replacement.

Vitamin B12 Deficiency

Dahiliye (İç Hastalıkları)

Vitamin B12 deficiency can cause megaloblastic anaemia, neurological symptoms, and cognitive impairment. Early treatment with intramuscular or oral B12 largely prevents irreversible complications.

Hypertension (High Blood Pressure) Management

Dahiliye (İç Hastalıkları)

Hypertension is often called the silent killer because it progresses symptom-free for years and can damage the heart, brain, kidneys, and eyes. Regular monitoring, lifestyle change, and evidence-based drug therapy dramatically reduce cardiovascular risk.

Chronic Kidney Disease

Dahiliye (İç Hastalıkları)

Chronic kidney disease is one of the most common complications of chronic conditions such as diabetes and hypertension, and can be silent in its early stages.

Hepatitis B (HBV)

Dahiliye (İç Hastalıkları)

Hepatitis B is a DNA virus infection causing acute and chronic hepatitis with risk of cirrhosis and hepatocellular carcinoma; diagnosis integrates HBsAg, HBeAg, anti-HBc, and HBV DNA with management based on disease phase using nucleos(t)ide analogues (entecavir, tenofovir) and universal infant vaccination.

Hepatitis C (HCV)

Dahiliye (İç Hastalıkları)

Hepatitis C is an RNA virus causing chronic hepatitis that may progress to cirrhosis and hepatocellular carcinoma; modern direct-acting antiviral (DAA) pangenotypic regimens (sofosbuvir/velpatasvir, glecaprevir/pibrentasvir) achieve sustained virologic response over 95% in 8–12 weeks with universal adult screening and cure for nearly all patients.

Fatty Liver Disease

Dahiliye (İç Hastalıkları)

Non-alcoholic fatty liver disease (NAFLD) is closely related to obesity and metabolic syndrome and is largely reversible with early treatment.
