What is Cholangiocarcinoma?

Cholangiocarcinoma is a malignant tumor originating from the epithelial cells of bile ducts.

Anatomically classified into intrahepatic (10%), perihilar/Klatskin (50-60%), and distal extrahepatic (20-30%) types — each with distinct clinical presentations and treatment approaches.

Underlying chronic biliary inflammation drives carcinogenesis, with molecular alterations including FGFR2 fusions and IDH1/IDH2 mutations now serving as therapeutic targets in intrahepatic disease.

Symptoms

Painless obstructive jaundice with pruritus (perihilar and distal forms)
Right upper quadrant abdominal discomfort or dull pain
Unintentional weight loss, anorexia, fatigue
Acholic stools and dark urine from biliary obstruction
Cholangitis: fever, chills, jaundice (Charcot triad)
Hepatomegaly or palpable mass in advanced intrahepatic disease
Often asymptomatic until disease is advanced

Risk Factors

Primary sclerosing cholangitis (lifetime risk 5-15%)
Liver fluke infection (Opisthorchis viverrini, Clonorchis sinensis) in Southeast Asia
Hepatolithiasis (intrahepatic stones)
Choledochal cysts
Caroli disease and congenital ductal anomalies
Hepatitis B and C viruses, cirrhosis
Toxin exposure (Thorotrast historical, asbestos)
Inflammatory bowel disease (independent of PSC)

When to See a Doctor?

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

  • New painless jaundice with pruritus or weight loss
  • Persistent right upper quadrant pain in patient with known liver disease
  • Worsening cholestatic enzymes in primary sclerosing cholangitis
  • Suspicious biliary stricture on imaging
  • Recurrent cholangitis episodes

Treatment Methods

01
Surgical resection — only curative option (R0 resection critical)
02
Liver transplantation in selected unresectable perihilar cases (Mayo protocol with neoadjuvant chemoradiation)
03
Adjuvant capecitabine after R0/R1 resection (BILCAP regimen)
04
First-line systemic: gemcitabine + cisplatin + durvalumab for advanced disease
05
Targeted therapy: pemigatinib/futibatinib for FGFR2 fusions, ivosidenib for IDH1 mutations
06
Biliary drainage with stenting (ERCP or PTC) for symptomatic obstruction
07
Photodynamic therapy and intraductal brachytherapy in selected cases
08
Multidisciplinary care with hepatobiliary surgery, oncology, gastroenterology, and radiation oncology

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.
