small cell lung CA: 25%
non-small cell lung CA: 75% |
|
|
what does squamous cell lung CA look like on CXR?
|
centrally located cavitation
|
|
|
describe the different locations of common lung CAs
|
SCLC - central
SCC - central adenocarcinoma - peripheral LCC - peripheral |
|
|
which lung CA has the lowest assn with smoking?
|
adenocarcinoma
|
|
|
how is NSCLC staged?
|
primary TNM system
|
|
|
how is SCLC staged?
|
limited:
- confined to chest + supraclavicular nodes - no cervical/axillary nodes extensive: - outside of chest + supraclavicular nodes |
|
|
what are the findings of superior vena cava (SVC) syndrome?
|
facial fullness
facial/arm edema dialated veins over ant.chest/arms/face JVD |
|
|
what causes superior vena cava (SVC) syndrome?
|
obstruction of the SVC by a mediastinal tumor
(mcc - SCLC) |
|
|
what is Horner's syndrome?
|
tumor invasion of cervical sympathetic chain leading to the following features:
- unilateral facial anhidrosis - ptosis (droopy eyelid) - miosis (pupillary contriction) |
|
|
what is Pancoast's tumor?
|
apical lung CA involving C8 + T1/2 nerve roots
- shoulder pain/weakness down arm - usually SCC - assd with Horner's (60%) |
|
|
what are the mc sites of metastasis in lung CA?
|
"bbagl"
brain bone adrenal glands liver |
|
|
what are the (6) paraneoplastic syndromes seen in lung CA?
|
SIADH
ectopic ACTH secretion PTH-like hormone secretion hypertrophic pumonary osteoarthropathy Eaton-Lambert syndrome digital clubbing |
|
|
which (3) paraneoplastic syndromes are assd with SCLC?
|
SIADH
ectopic ACTH secretion Eaton-Lambert syndrome |
|
|
which (2) paraneoplastic syndromes are assd with SCC?
|
PTH-like hormone secretion
hypertrophic pumonary osteoarthropathy (also adenocarcinoma) |
|
|
what does Eaton-Lambert syndrome look like clinically?
|
similar to MG:
- proximal muscle weakness/fatigability - decr DTRs - paresthesias (lower>upper) |
|
|
what CXR findings are assd with a benign lesion?
|
no changes over a 2-year period
|
|
|
describe NSCLC treatment
|
surgery is #1 (if no mets)
- radiation important adjunct - chemo is questionable |
|
|
describe SCLC treatment
|
chemo is #1
- usually not surgically resectable - radiation for limited stage, not extensive stage |
