Liver Cancer, Abscess, and Pancreatic Cancer

Liver Cancer

Transition from Cirrhosis
  • Patients with hepatic issues, including cirrhosis, may require extensive care:

    • Further care in a rehabilitation facility.

    • Involvement of dietitians to ensure proper nutrition.

    • Neurology involvement for related complications.

Causes of Liver Cancer
  • Metastasis: Cancer cells spreading from other primary sites (e.g., lungs) to the liver.

  • Hepatitis B and C: These viral infections are major risk factors for liver cancer.

    • Transmission: Primarily through blood contact (e.g., sharps injuries, intravenous drug use, sexual contact).

      • Healthcare Providers: Needle sticks are a significant source of exposure, often due to improper sharps disposal or rushing procedures.

  • Age: Increased age correlates with a higher risk of various cancers, including liver cancer.

  • Toxin Exposure:

    • Smoking

    • Alcohol Consumption

  • Obesity: Poor self-care and obesity contribute to increased cancer risk.

  • Cirrhosis: The presence of scar tissue and cellular changes in a cirrhotic liver can lead to the development of malignant cells.

Spread of Liver Cancer
  • The liver's extensive portal system and rich vascularity facilitate the easy spread of malignant cells to other body parts.

  • Nearby Structures: Cancer can spread to the gallbladder, pancreas, and lungs.

  • Distant Sites: Spread to the breast and stomach is also possible.

  • Heart Cancer: Cancer in the heart is rare due to the unique nature of cardiac cells and constant movement.

Diagnosis of Liver Carcinoma
  • Laboratory Tests:

    • Liver Function Tests (LFTs)

    • Complete Blood Count (CBC)

  • Imaging:

    • Ultrasound

    • CT Scan

    • PET Scan: Utilizes a radioisotope that illuminates areas with cancer cells, making them visible as glowing regions on the scan.

  • Biopsy: Liver biopsy is a definitive diagnostic tool.

    • Nursing Interventions for Liver Biopsy:

      • Post-procedure, position the patient on their right side for 2 hours to apply pressure and reduce bleeding risk.

      • Place a towel or pillow under the patient's right side.

      • Monitor vital signs every 15 minutes to detect any signs of bleeding, especially given the fragile nature of a diseased liver.

Clinical Manifestations of Liver Cancer
  • Hepatomegaly: Enlargement of the liver as it attempts to compensate for damage and regenerate around scar tissue.

  • Weight Loss: Caused by malnutrition (impaired toxin processing, leading to loss of appetite) and the systemic effects of cancer, especially if it has metastasized to areas like the stomach.

  • Peripheral Edema: Due to portal hypertension, which causes fluid to shift from the intravascular space into the tissues, similar to right-sided heart failure.

  • Dehydration: A consequence of fluid shifting out of the intravascular space.

    • Nursing Intervention: Administer intravenous (IV) fluids, especially if the patient is NPO or at risk for gastrointestinal (GI) bleeding, to replace fluids and electrolytes.

  • Ascites: Accumulation of fluid in the abdominal cavity.

    • Nursing Interventions: Daily girth measurements, regular assessment of the abdomen (peristaltic waves might be visible).

  • Pain: Typically located in the right upper quadrant and/or epigastric region.

    • Initially mild, but progresses as the disease advances.

    • Pain Management Consideration: Liver's role in drug metabolism requires careful selection of medications to avoid further burdening the organ.

  • Jaundice: Observable mainly in the sclera (eyes) and oral mucosa, as well as the skin.

  • Nausea and Vomiting

  • Enlarged Jugular Veins: Due to increased pressure.

Medical Management of Liver Cancer
  • Palliative Care: Focused on symptom management and improving quality of life.

  • Surgery:

    • Excision of the tumor.

    • Resection of a liver lobe. Note: If the liver is severely damaged by cirrhosis, it may not be able to regenerate the resected lobe effectively.

  • Chemotherapy:

    • Side effects can include weight loss, nausea, vomiting.

    • Monitoring White Blood Cell (WBC) count is crucial, as chemotherapy often lowers it (
      \text{Normal WBC range: } 5 \text{ to } 10 \times 10^3), impairing the immune system.

Liver Abscess

Definition and Impact
  • An encapsulated infection (abscess) on the liver.

  • Significantly impairs liver functioning.

  • Rapid Systemic Spread: Due to the liver's portal vasculature, an open abscess can quickly lead to systemic infection and septic shock.

Causes of Liver Abscess
  • Infection: Bacteria tend to localize where the body's defenses are weakest, such as in a compromised or non-functioning liver.

  • Low Immune System: Immunosuppression (e.g., from chemotherapy) increases susceptibility to abscess formation and bacterial overrun.

  • Perforation: Contents from a perforated organ (e.g., ruptured colon spilling fecal contents and E. Coli into the abdominal cavity) can migrate to and infect the liver.

    • Signs of Intestinal Perforation: Abdominal distention, diaphoresis, rigid abdomen.

Clinical Manifestations of Liver Abscess
  • Flu-like Symptoms: Chills, fever.

  • Pain: Abdominal pain, tenderness, and discomfort.

  • Hepatic Enlargement: Hepatomegaly.

  • Anemia

  • Flake-colored Stools and Dark Urine: Indicate issues with bile flow (gallbladder/bile duct obstruction due to abscess or related bacteria).

  • Diaphragm Irritation: Pressure on the diaphragm can cause chronic hiccups.

  • Weight Loss and Malaise: Cachexia (more than 10\% body weight loss, muscle wasting).

  • Onset: Symptoms can vary, with some developing slowly. Undiagnosed liver abscesses have a 100\% mortality rate.

Diagnosis of Liver Abscess
  • Imaging: CT scan, Ultrasound.

  • Biopsy: Liver biopsy.

Medical Management of Liver Abscess
  • Antibiotic Therapy:

    • Typically administered for 4 to 6 weeks.

    • Patient Education: Emphasize completing the entire antibiotic course (to prevent resistant bacteria) and increasing fluid intake (to flush out bacteria).
