lung cnacer Flashcards
The two classifications of lung cancer
NSCLC and SCLC
What is the presentation of small cell lung cancer
Really aggressive tumours that present having metastsised initally will respond well to chemotherapy but relapse quickly
Which type of lung cancer are the paraneoplastic syndromes associated with
SCLC - SIADH cushings syndrome and lambert eaton myesthenic syndrome
What are the different types of NSCC
Squamous cell cancinoma -
Adenocarcinoma -
Large cell carcinoma -
mesothelioma , carcinoid sarcoma and lymphoma
Features of squamous cell carcinoma
close to bronchi and linked to cigarette smoking - also associated with PTH related peptite that can lead to malignant hypercalcaemia
Features of adenocarcinoma
peripheral more frequent in women who dont smoke with asbestos exposure. Associated with activating mutations in EGFR and ALK
Features of large cell carcinoma
less differentiated and metastaise early
When is a CT scan used
to asses the extent of the disease local and distant mets
When is a PET scan used
in pts with operable disease to check distant mets not picked up by CT
When is bronchoscopy used
to see bronchial tree to allow for biopsy and bronchial washing
When is PFT used
for assessing underlying lung disease
When is cardiopulmonaary excersize testing used
for patietn considered for surgical resection to insure they are fit enough for surgery
Management of SCLC
palliative chemo
if localised radiotherapy
if peripheral chemotherpy
prophylactic crainial irratidations
How are complications such as SCLO and spinal cord compression treated
with chemotherapy as SCLC is very sensitive to chemotherapy but most relapse
How is radiothaerapy used to treat primary tumour
local control is achieved therefore relapse occurs in another site which means improved palliative control
Why is prophylactic crainial irradiation used
prevents the dev of brain mets offered to patients with good response to chemotherapy
Which lung cancer should be considered systemic
SCLC - as it presents early with mets
Management of NSCLC
Surgery -
Radiotherapy -
Chemotherapy -
When is sugery offered in NSCLC
if stage 1 and 2 - mediastinal involvement is CI to surgery adjuvant chemotherapy will be needed in positive surgical margins
When is chemotherapy offered and how in NSCLC
metastatic and locally advnaced where no activating mutation/ translocation or PDL1 expression
Carboplatin and gemcitabine or carboplatin/cisplatin and pemetrxed
Second line docetaxel
When is radiotherapy offered in NSCLC
Sterotactic ablative body radiothrapy peripherally in the lungs - delivers a small number of large dose radiptherapy to a small conformal volume arounf the lung tumour
Which patients are tested for egfr and ALK at time of diagnosis and what does it indicate
patients with adenocarcinoma and it indicaties that tyrosine kinase inhibtors can be used like afatinib erlotinib getfitnib for EGFR
CRIZOTINIB FOR ALK
if on targeted regime for egfr and alk can they be treated with second time targeted therapies osimertinib and ceritinib rather than the standard chemo of targeteted regime
yes
If patient has advnaced NSCLS with PDL1 expression what can be used
Immunotherapy before or after therapy can have a prolonged benefit
