Study Notes
Liver Cancer
- 3rd leading cause of cancer death worldwide and in the Philippines
- 4th in incidence in the Philippines
Etiology and Pathophysiology
-
Primary Liver Cancers:
- Hepatocellular Carcinoma (HCC)
-
Liver Metastasis:
- More common than primary liver cancer
- 2.5 times more frequent than primary liver cancers
- Originates from gastrointestinal tract (GIT), breast, and lung
- Ideal location for malignant cells
Causes of Primary Liver Cancers
- Cirrhosis
- Chronic hepatitis B virus (HBV) and hepatitis C virus (HCV)
- Exposure to chemical toxins (e.g., arsenic, vinyl chloride)
- Cigarette smoking (particularly when combined with alcoholism)
- Aflatoxin (or other toxic molds)
Clinical Manifestations (Early)
- Early liver cancer: Symptoms are absent or subtle
- Hepatomegaly
- Splenomegaly
- Fatigue
- Peripheral edema, ascites
Clinical Manifestations (Late)
- Fever/chills
- Jaundice
- Anorexia
- Weight loss
- Palpable mass
- Right upper quadrant (RUQ) pain
Diagnostics
- Ultrasound
- Serum AFP (alpha-fetoprotein) /TAAT
- CT Scan
- MRI
- Biopsy
- Colonoscopy
- CEA (carcinoembryonic antigen)
Medical Management - Prevention
- Treat chronic HBV and HCV infections
- Treat chronic alcohol use
- Screen at-risk patients (those with cirrhosis and NAFLD)
Medical Management - Treatment
-
Cure:
- Liver resection (partial hepatectomy)
- Liver transplantation (for early-stage liver cancer with impaired function)
-
Nonsurgical therapies:
- Percutaneous ablation
- Laparoscopic ablation
- Microwave ablation
- Radiofrequency ablation
- Transarterial chemoembolization (TACE)
- Chemotherapy and immune-based therapy
- Monoclonal antibodies
- Tyrosine kinase inhibitors
- Immune checkpoint inhibitors
Medical Management - Staging
- Treatment/prognosis correlated with staging
- TNM (tumor, node, metastasis) commonly used to stage
- Staging is vital for determining the appropriate treatment. Stage 0 to Stage IV
- Specific TNM classifications and 5-year survival rates given
Colorectal Cancer
- 3rd in cases worldwide and in the Philippines
- 2nd cause of cancer death worldwide
- 4th cause of cancer death in the Philippines
Risk Factors for Colorectal Cancer
- Risk is higher in men
- Risk increases with age
- Alcohol (>=4 drinks per week)
- Cigarette smoking
- Family history of CRC in first-degree relatives
- History of familial adenomatous polyposis (FAP)
- History of hereditary nonpolyposis colorectal cancer
- Obesity
- Personal history of colon cancer, inflammatory bowel disease (IBD), or diabetes
- Red meat (>=7 servings/week)
Pathophysiology
- CRC typically begins as a polyp
- Polyps usually evolve into adenomas over 10 to 20 years.
- As tumors grow, they can invade and penetrate the walls.
- Cancer cells can spread to lymph nodes and the vascular system.
Clinical Manifestations - Presentation
- Colorectal cancer develops slowly
- Symptoms are often absent until the disease is advanced
- Nonspecific in early disease, potentially including Fatigue, Weight loss, Abdominal pain, tenderness, and change in bowel habits
- Possible later-stage manifestations including abdominal pain, tenderness, change in bowel habits, maybe a palpable abdominal mass, hepatomegaly, ascites, bleeding (more common on the right), hematochezia (usually left), right-sided diarrhea, bowel obstruction, bleeding perforation, peritonitis, and fistula formation
Diagnostics
- Screening tests (45 to 75):
- Flexible sigmoidoscopy (every 5 years)
- Colonoscopy (every 10 years)
- Double contrast barium enema (every 5 years)
- CT colonography (virtual colonoscopy) (every 5 years)
- Other tests:
- Colonoscopies
- CEA (carcinoembryonic antigen)
- Biopsy of polyps
Medical Management - Surgical Therapy
- Goals: Complete resection of the tumor, thorough exploration to assess spread, removal of all draining lymph nodes, restoration of bowel function
-
Stages:
- Stage 1 and 2: Resection
- High-risk stage 2: Chemotherapy after surgery
- Stage 3: Surgery and chemotherapy
- Stage 1, 2, and 3 generally have good prognoses (higher survival rates)
Medical Management - Other Treatments
- Neo-adjuvant therapy
- Palliative therapy
- Adjuvant therapy (recommended for stage 3 tumors)
- Targeted therapies (angiogenesis inhibitors, multikinase inhibitors)
- Radiation therapy (adjuvant to surgery & chemo; palliative for metastasis)
Nursing Management - Diagnoses
- Altered bowel elimination
- Anxiety
- Difficulty coping
Nursing Management - Implementation
- Follow screening guidelines
- Routine postoperative care
- Sterile dressing changes & drain care, pt/caregiver teaching on ostomy
- Psychological support
