🧠 2️⃣ Mnemonics
Mnemonic Title:
TNM Staging
Mnemonic Word:
“Tumor Nodes Move”
Meaning:
- T → Tumor depth
- N → Node involvement
- M → Metastasis
Mnemonic Title:
Features of Left-Sided Colon Cancer
Mnemonic Word:
“COP”
Meaning:
- C → Constipation
- O → Obstruction
- P → Pencil-thin stool
Mnemonic Title:
Features of Right-Sided Colon Cancer
Mnemonic Word:
“LAW”
Meaning:
- L → Lethargy
- A → Anemia
- W → Weight loss
📋 3️⃣ Memory Tables
Table 1 — Right vs Left-Sided Colon Cancer
| Feature | Right-Sided Cancer | Left-Sided Cancer |
|---|---|---|
| Stool consistency | Liquid | Solid |
| Common presentation | Anemia | Obstruction |
| Bleeding | Occult | Visible |
| Growth pattern | Exophytic | Annular |
Table 2 — Important Investigations
| Investigation | Main Purpose |
|---|---|
| Colonoscopy | Visualization + biopsy |
| CT Scan | Detect spread/metastasis |
| MRI Pelvis | Local rectal staging |
| CEA | Follow-up monitoring |
⚡ 4️⃣ Rapid Revision Points
Must Remember:
• Most colorectal cancers are adenocarcinomas.
• APC mutation is an early event.
• Adenomatous polyps are premalignant.
• Right-sided tumors commonly cause anemia.
• Left-sided tumors commonly cause obstruction.
• Rectal carcinoma may cause tenesmus.
• Liver is the most common metastatic site.
• Colonoscopy with biopsy confirms diagnosis.
• MRI pelvis is important in rectal cancer staging.
• TNM staging guides prognosis and treatment.
• Surgery is the main curative treatment.
• CEA is mainly used for follow-up.
🩺 5️⃣ Clinical Memory Hooks
Clinical Hook:
Right-sided colon cancer → Iron deficiency anemia
Clinical Hook:
Left-sided colon cancer → Intestinal obstruction
Clinical Hook:
Rectal carcinoma → Tenesmus + rectal bleeding
Clinical Hook:
Portal venous drainage → Liver metastasis
Clinical Hook:
APC mutation → Adenoma-carcinoma sequence
