🫁FREE MSRA PODCAST –Small-Cell Lung Cancer (SCLC)Everything you needto revise this aggressive, fast-growing cancerfor the MSRA, summarised in one episode. 🧠Key Learning Points📌Definition• Small-Cell LungCancer (SCLC) is a highly malignantneuroendocrine tumour of the bronchial epithelium• Rapid growth,early metastasis, poor prognosis• Accounts for ~15%of all lung cancers📌Causes• >90% caused by smoking (including passivesmoking)• Other risks:asbestos, radon gas, family history📌Symptoms• Persistent cough (>6 weeks), dyspnoea, chestpain, weight loss, fatigue, haemoptysis• Dysphagia, hoarseness, recurrent infections• Paraneoplastic syndromes (e.g. SIADH, Cushing’ssyndrome)• Symptoms of distant metastases: bone pain, headaches,confusion, hepatomegaly📌Diagnosis🧪Bloods: FBC, U&Es (look for hyponatraemia), LFTs, LDH🩻Imaging:• Chest X-ray →initial screen• Contrast-enhanced CT chest• PET-CT → staging• MRI brain → rule out CNS mets🧫Tissue biopsy: via bronchoscopy or EBUS-TBNA for lymph nodes🧠Staging:• Limited stage – confined to one hemithorax andtreatable in one radiation field• Extensive stage – spread to opposite lung,distant mets (e.g., liver, brain)📌Management💊Limited stage:• Concurrent chemoradiotherapy (cisplatin +etoposide)• Followed by prophylactic cranial irradiation (PCI)💊Extensive stage:• Platinum-based chemotherapy(cisplatin/carboplatin + etoposide)• Immunotherapy (e.g. atezolizumab) often added🧘 Non-pharmacological:• Smoking cessation• Palliativeradiotherapy (e.g. bone or brain mets)• Nutritional andpsychological support🚨Emergencies:• Superior vena cava obstruction (SVCO) →requires urgent management (e.g. radiotherapy/stenting)📌Prognosis• 1-year survival: ~40%• 5-year survival: ~15% (UK data)• Prognosis worsewith extensive disease, male sex, and older age• Slightly bettersurvival in females and younger patients• Rare early-stageSCLC has better outlook (up to 60% 5-year survival) 📎More SCLC MSRAResources:📝 Revision Notes: https://www.passthemsra.com/topic/small-cell-lung-cancer-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/small-cell-lung-cancer-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/small-cell-lung-cancer-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/small-cell-lung-cancer-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/respiratory-for-the-msra/ Hashtags#MSRA#SmallCellLungCancer #SCLC #MSRARevision #LungCancer #RespiratoryMSRA#ParaneoplasticSyndrome #MSRAFlashcards #MedicalEducation #MSRAOnlineRevision#PassTheMSRA
