Smoking
Can you treat SCLC with resection
NO
Characteristics of Squamous cell carcinoma
Most likely to present with hemoptysis, Intraluminal sessile or polypoid masses, arises from bronchial epithelium (MC) - 2nd/3rd bronchus
4 types of NSCLC
Adenocarcinoma
Squamous cell carcinoma
Large cell carcinoma
Bronchioalveolar cell carcinoma
Inspiratory Crackles

Wheezing
Smoke inhalation Acute Gastric acid aspiration PE
Pancoast syndrome
Lung tumor of the superior sulcus at extreme apex of lung
MC SCLC paraneoplastic syndrome
SIADH
Recurrent laryngeal Nerve palsy is
Tumor destruction of recurrent laryngeal nerve and New onset hoarseness
SCLC pathogenesis
Begins centrallty and infilitrates submucosally which narrows/obstructs bronchus with out a luminal MASS
Reducing lung cancer burden lung term
Preventive is better than screening
Abrupt Severe hyponatremia
Cerebral edema, irritability, confusion, sezuires, coma
MC NSCLC paraneoplastic syndrome
Hypercalcemia
SIADH MOA
Too much ADH causes water retention and causes hyponatremia - <120 and concentrated urine >300 mol
Superior vena cava obstruction MOA
Tumor causes venous obstruction of head, neck, UE
S/S of SVC obstruction
Dyspnea, facial swelling, congestion, cough, arm swelling, chest pain
NSCLC over all charcteristics
Slow spread, can resection early DZ, responds to chemo poorly
Who does adenocarcinoma effect most
Women and non-smokers
SCLC CXR
MC hilar mass with bulky mediastinal adenopathy
TXT for NSCLC stage III and IV
Chemo and radiation
Another name for SCLC
Oat cell
Who does bronchial carcinoid effect
<60 yo
Before lung surgery what test is required?
PFT’s for baseline and determining post-op lung fx
MC cancer worldwide & leading cause of cancer deaths
Lung cancer
Does mesothelioma have a smoking correlation
No
Horner syndrome - triad
Ipsilateral miosis, ptosis anhidrosis
Horner syndrome MOA
paravertebral sympatheric chain involvement
Staging SCLC
Always metastatic at time of ID- either limited (one side of lung and regional nodes) or Extensive (MC) both lungs with distant spread
Plain Crackles
PE, ARDS,
Other tumor complications (2)
Recurrent laryngeal Nerve palsy and Phrenic nerve palsy
