Question

Screening protocol for pancreatic cancer: present status.

Hint:

Early screening for pancreatic cancer is critical but currently limited to high-risk populations. Ongoing research is focused on finding more effective and accessible screening methods.

Answer 1

Pancreatic cancer is often diagnosed at advanced stages due to the lack of early symptoms. Screening for pancreatic cancer is an area of active research, but current protocols for screening are limited to high-risk individuals.
Step 1: Screening Criteria:
1. High-Risk Groups: Screening is recommended for individuals with a family history of pancreatic cancer, genetic predispositions (e.g., BRCA mutations), and certain inherited syndromes like Lynch syndrome or familial atypical multiple mole melanoma (FAMMM) syndrome.
2. Age and Lifestyle Factors: Individuals over the age of 50 with a history of smoking and chronic pancreatitis may also be considered for screening.
Step 2: Screening Methods:
1. Endoscopic Ultrasound (EUS): EUS is the most commonly used method for screening high-risk individuals. It provides detailed images of the pancreas and can detect small tumors.
2. MRI and CT Scans: These imaging techniques are used for monitoring high-risk patients and detecting pancreatic abnormalities.
Step 3: Challenges and Future Directions:
1. Lack of Effective Biomarkers: Currently, there are no widely used blood tests for early detection of pancreatic cancer, making screening dependent on imaging techniques.
2. Cost and Accessibility: The cost and availability of advanced imaging techniques like EUS limit their use in widespread screening.
