To target the EGFR protein
Study Notes
Risk Factors
- Age: Risk increases with age, most cases occur in people over 65
- Family history: Having a family history of pancreatic cancer, especially in first-degree relatives
- Genetic mutations: Inherited syndromes such as BRCA2, p16, and hereditary pancreatitis
- Smoking: Long-term smoking increases the risk of pancreatic cancer
- Obesity: Being overweight or obese
- Diabetes: Having type 2 diabetes, especially if it's long-standing
- Pancreatitis: Having chronic pancreatitis, a long-term inflammation of the pancreas
- Diet: A diet high in processed meat and low in fruits and vegetables
- Occupational exposure: Exposure to certain chemicals, such as pesticides and dyes
Symptoms and Diagnosis
-
Common symptoms:
- Abdominal pain or discomfort
- Weight loss
- Fatigue
- Loss of appetite
- Nausea and vomiting
- Yellowing of the skin and eyes (jaundice)
-
Diagnosis:
- Imaging tests: CT, MRI, and PET scans
- Endoscopic ultrasound (EUS) to examine the pancreas and surrounding tissues
- Biopsy: Collecting a sample of pancreatic tissue to examine for cancer cells
- Blood tests: Checking for biomarkers, such as CA 19-9, to help diagnose pancreatic cancer
Stages and Prognosis
-
TNM staging system:
- T (tumor): Size and location of the primary tumor
- N (node): Spread to lymph nodes
- M (metastasis): Spread to distant organs
-
Stages:
- Stage I: Cancer is localized to the pancreas
- Stage II: Cancer has spread to nearby tissues or lymph nodes
- Stage III: Cancer has spread to major blood vessels or nearby organs
- Stage IV: Cancer has spread to distant organs
-
Prognosis:
- 5-year survival rate: Around 9% for all stages
- Early detection and treatment improve prognosis
Treatment Options
-
Surgery:
- Whipple procedure: Removing the tumor and surrounding tissues
- Distal pancreatectomy: Removing the tail of the pancreas
-
Chemotherapy:
- Gemcitabine: A common chemotherapy drug for pancreatic cancer
- Combination chemotherapy: Using multiple drugs to treat the cancer
-
Radiation therapy:
- External beam radiation: Using a machine to deliver radiation to the tumor
- Stereotactic body radiation therapy (SBRT): Delivering high doses of radiation to the tumor
-
Targeted therapy:
- Erlotinib: A drug that targets the EGFR protein
-
Palliative care:
- Managing symptoms and improving quality of life
- May include pain management, nutrition support, and counseling
