Understanding Pancreatic Cancer

Introduction

• Pancreatic cancer has one of the worst survival rates, with a 5-year survival rate of only 12-13%.
• This cancer is often detected late, making it particularly deadly.

The Pancreas

• Location: Posterior to the stomach in the abdominal cavity.
• Structure: Composed of the head, body, and tapering tail.
• Function:
  • Endocrine: Secretes hormones like insulin and glucagon into the bloodstream.
  • Exocrine: Secretes digestive enzymes into the duodenum.

Why Pancreatic Cancer is Deadly

1. Early Detection Challenges:

   • Few symptoms in early stages such as back pain or abdominal pain are often ignored.
   • No universal screening or blood test currently available.

2. Aggressiveness and Resistance:

   • Tumors grow quickly and invade nearby organs.
   • Tumors build a dense stroma that resists standard treatments (chemotherapy, radiation).

3. Impact of Late Detection:

   • Symptoms like jaundice arise too late when survival rates drop significantly.

Understanding Cancer Types and Survival Rates

• Ductal Adenocarcinoma: The most common type, originating in the pancreatic ducts.
• Survival Rates by Stage:
  • Localized (within the pancreas): up to 44%.
  • Regional Spread: 16%.
  • Distant Spread: 3%.

Risk Factors and Prevention

• Modifiable Risks:
  • Smoking, obesity, lack of physical activity, and chronic alcohol consumption leading to pancreatitis.
• Non-Modifiable Risks:
  • Family history and genetics.
• Lifestyle Improvements: Diet and exercise can help reduce risks.

Treatment Options

• Challenges with Treatment:
  • Tumors often resistant to chemotherapy and radiation.
• Surgical Options:
  • Early-stage cancer may be treated with surgery, notably the Whipple procedure (pancreatico duodenectomy).

Conclusion

• Pancreatic cancer remains a significant challenge due to late detection and treatment resistance.
• Awareness of risk factors and early symptoms can potentially improve outcomes.
• Advances in screening and treatment methods are crucial for improving survival rates.
