lung Flashcards
which kind of lung cancer is more likely to be peripheral
adenocarcinoma (also linked to non smokers)
what is the latent period of asbestos exposure
30-40 years
common presentation of mesothelioma
dyspnoea, chest pain, coughing, weight loss
IX for mesothelioma
CXR may show pleural effusion or pleural thickening
-if pleural effusion is present aspirate and do MC+S
-if negative - thoracoscopy
are distal mets rare or common in mesothelioma
rare
what is the 2WW for lung cancer
anyone who has CXR signs of lung cancer or anyone over 40 who has unexplained hameoptysis
OTHERWISE - do an urgent chest X-ray if suspecting (eg anyone over 40 with cough and ex smoker)
what is Lambert eaton myasthenia syndrome
in SCLC get antibodies against voltage gated calcium channels. Presents with weakness in pharyngeal muscles, ptosis and diplopia. but these symptoms get better with use!
which is the most common type of lung cancer
adenocarcinoma
which lung cancers are always linked to smoking
squamous cell and SCLS
what blood would you do when suspected a lung cancer
FBC, U+E, calcium, LFT (to indicate hepatic metastasis), INR
what CXR signs will you see in a lung cancer
hilar enlargement, peripheral opacity, pleural effusion, lobar collapse
what’s a bronchoscopy vs EBUS
a bronchoscopy directly visualises the lung tissue where as an EBUS uses ultrasound to sample the lymph nodes
how can you take a biopsy if the lung cancer is more peripheral
Ct guided biopsy
what types of surgery are available for lung cancer
1) wedge resection
2) lobectomy
3) pneumonectomy
what’s firstline imaging for lung cancer
firstline = CXR
then do CT if CXR negative but high suspicion
then bronchoscopy and biopsy for staging
then PET-CT for staging
