What is Nutrition in the Cancer Patient?

Cancer-related malnutrition results from reduced intake (anorexia, mucositis, nausea), increased losses (vomiting, diarrhea, fistulas), and altered metabolism (cachexia, inflammation). It is common in upper gastrointestinal, pancreatic, head and neck, and lung cancers and worsens with advanced disease.

Nutritional screening with validated tools at diagnosis and during treatment identifies at-risk patients. Comprehensive assessment evaluates weight loss, body composition, muscle function, dietary intake, and symptoms. Cancer cachexia is a multifactorial syndrome requiring multimodal intervention.

Management includes individualized dietary counseling, energy- and protein-dense foods, oral nutritional supplements, and management of symptoms limiting intake. When oral intake is inadequate, enteral feeding (nasogastric, PEG) is preferred over parenteral nutrition; parenteral support is reserved for nonfunctional gastrointestinal tract.

Symptoms

Unintentional weight loss exceeding 5 to 10 percent
Loss of muscle mass and strength
Anorexia, early satiety, taste changes
Mucositis, dysphagia, nausea, vomiting, diarrhea
Fatigue and reduced functional capacity

Risk Factors

Upper gastrointestinal, pancreatic, head and neck, lung cancers
Advanced disease and multiline therapy
Severe symptoms from radiation or chemotherapy
Surgery affecting digestion or absorption
Older age, comorbidities, social isolation

When to See a Doctor?

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

  • Significant unintentional weight loss
  • Persistent eating problems or symptoms
  • Plans for major surgery, chemotherapy, or radiotherapy
  • Difficulty maintaining hydration
  • Need for tube feeding or parenteral support

Treatment Methods

01
Routine nutritional screening at diagnosis and through treatment
02
Individualized counseling by oncology dietitian
03
Energy- and protein-dense foods and oral supplements
04
Symptom management for nausea, mucositis, dysphagia
05
Enteral feeding via nasogastric tube or gastrostomy when needed
06
Parenteral nutrition only when gastrointestinal tract is nonfunctional
07
Multimodal cachexia care including exercise and pharmacotherapy

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.
