What is Management of Malignant Ascites?

Malignant ascites complicates ovarian, gastrointestinal, breast, and pancreatic cancers and reflects peritoneal carcinomatosis with increased capillary permeability and lymphatic obstruction. Symptoms include abdominal distension, early satiety, dyspnea, and umbilical hernia formation that signal advanced disease.

Initial assessment includes abdominal ultrasound or computed tomography, paracentesis for cytology and serum-ascites albumin gradient, and exclusion of cirrhotic ascites or non-malignant causes. Cytology yield is histology dependent and ranges from forty to ninety percent in different primaries.

First-line management uses spironolactone-based diuretics in patients without portal hypertension, large-volume paracentesis for symptom relief, and intravenous albumin replacement for hemodynamic support. Tunneled peritoneal catheters allow ambulatory home drainage for refractory ascites. Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy benefits selected patients with low-grade ovarian, appendiceal, or peritoneal mesothelioma disease.

Symptoms

Progressive abdominal distension
Early satiety and reduced food intake
Dyspnea due to diaphragmatic elevation
Lower extremity edema
Umbilical or inguinal hernia formation

Risk Factors

Ovarian or peritoneal carcinoma
Gastric or pancreatic cancer
Colorectal carcinoma with peritoneal disease
Mesothelioma peritoneal involvement
Hormone receptor-positive breast cancer

When to See a Doctor?

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

  • When abdominal distension limits comfort
  • When dyspnea or early satiety appears
  • When new abdominal pain emerges
  • When fever or peritonitis is suspected
  • When refractory ascites needs durable drainage

Treatment Methods

01
Abdominal imaging with paracentesis
02
Spironolactone-based diuretic therapy
03
Large-volume paracentesis for symptom relief
04
Intravenous albumin replacement
05

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.
