Colon Cancer:Basic Facts & Figures:
• 2nd & 3rd most common cancers in females and males.• 9% of cancer related deaths.• 90% occurring around the age of 40 – 50 years.• OAS for entire patients = 65%.• Metastatic disease: 5-year OAS = 10%.• Organ limited metastatic disease: 5-year OAS > 40%• Median survival of metastatic disease > 24 - 30 months.• Improved OAS with exposure to all available drugs.• Unified global ideal treatment algorhytm is still
controversial.

It’s MANDATORY! Greater accuracy of staging Fewer treatment delays Better outcome!

Take Home Message:
• mCRC is a real burden in daily practice.• Surgical resection of organ limited disease
Cure “The Race Toward Surgery”.• Changing landscape of disease Cure of
advancing & metastatic diseasebecame possible.
• Routine practice of MDT should be encouraged to get the beneficial outcome.
