Surg: Colorectal Cancer: Free MSRA Podcast

🎧 MSRA Podcast: Colorectal Cancer – From Polyps to Prognosis 🔍A complete, high-yield breakdown of one of the UK’s most common and exam-relevant cancers. This MSRA-focused deep dive simplifies red-flag symptoms, referral criteria, TNM staging, and treatment pathways — all in a clinical, revision-friendly format.🧠 What You’ll Learn:✅ Definition & Pathophysiology• Malignancy of colon or rectum (usually adenocarcinoma)• Most arise from benign polyps over years via dysplasia• Invade locally, spread to liver/lungs✅ Causes & Risk Factors• Age, family history, IBD (UC, Crohn’s), Lynch/FAP• Low fibre diet, obesity, red/processed meat• Smoking, alcohol, pelvic radiation🧠 Mnemonic: Age + Family Inflame Inherited Diabetes Lifestyle Adds Other Risks✅ Differential Diagnosis• Polyps, IBD, diverticular disease, IBS, haemorrhoids, ischaemic colitis✅ Epidemiology• 4th most common UK cancer (~42,000/year)• 44% diagnosed in 75+• Rectum = most common site• Often presents late✅ Clinical Features• Change in bowel habit• Rectal bleeding• Fatigue• Weight loss• Abdominal pain🧠 Mnemonic: ABC-FW📍 Right = anaemia/vague📍 Left = bleeding, tenesmus, obstruction🧪 Investigations• FBC, LFTs, FIT test, CEA marker• Colonoscopy/sigmoidoscopy + biopsy• CT TAP, rectal MRI for staging✅ TNM Staging• T1–T4 = depth• N0–N2 = lymph nodes• M0/M1 = mets• G1–G3 = cell differentiation🚨 Urgent Referral Criteria• Age 40+ + wt loss + abdo pain• Age 50+ + rectal bleeding• Age 60+ + anaemia or bowel change• <50 + rectal bleeding + ≥1 other symptom🧠 Don’t forget FIT as a red flag in symptomatic patients💉 Management (MDT Approach)• Surgery = curative (R/L hemicolectomy, anterior/APR resection)• Radiotherapy = rectal tumours• Chemo = adjuvant (stage 3), palliative• Targeted: cetuximab, bevacizumab• Molecular profiling increasingly used📈 Follow-Up• Regular CEA, CT, colonoscopy• NICE: 5 years of structured follow-up📉 Prognosis• 5-year survival ~45% overall• ~60% survive 7+ years if surgically resected• Stage at diagnosis is key🧯 Complications• Obstruction, perforation, anastomotic leak• Metastases• Chemo/radio side effects (fatigue, nausea, neuropathy)• Psychosocial: stoma, anxiety, QoL🛡️ Prevention Tips• High fibre, less processed meat• Exercise, weight control• Don’t smoke or binge alcohol• Screening at age 56+🧠 Final Thought:How will early detection evolve with AI, better biomarkers, and risk-based screening?📚 Free MSRA Resources• 📝 Notes:https://www.passthemsra.com/topic/colorectal-cancer-revision-notes/• 🧠 Flashcards:https://www.passthemsra.com/topic/colorectal-cancer-flashcards/• 📖 Q&A:https://www.passthemsra.com/topic/colorectal-cancer-accordion-qa-notes/• 📊 Quiz:https://www.passthemsra.com/topic/colorectal-cancer-rapid-quiz/https://www.passthemsra.com/quizzes/colorectal-cancer/• 🆓 Free Questions:https://www.freemsra.com#MSRA #ColorectalCancer #MSRAFlashcards #MSRAQuiz #GPExamPrep #FITtest #TNMStaging #PassTheMSRA #DeepDivePodcast #BowelCancer #NICEGuidelines
