| Question | Answer |
| What percentages of lung cancers are small cell vs. non-small cell? | 25% small cell 75% non-small cell |
| Jobs in which exposure to asbestos is common (4) | - Shipbuilding - Construction - Car mechanics - Painters |
| High levels of radon are found in _________. | Basements |
| Staging of NSCLC vs SCLC | NSCLC = TNM system SCLC = limited vs. extensive (limited = chest + supraclavicular nodes; extensive = outside of that area) |
| Superior vena cava (SVC) syndrome most commonly occurs with what type of lung cancer? | Small cell (occurs in 5% of cases) |
| Findings in SVC syndrome | - Facial fullness - Facial & arm edema - Dilated veins over anterior chest, arms, face - JVD |
| Why do 1% of lung cancer patients get hemidiaphragmatic paralysis? | Tumor destruction of phrenic nerve |
| Why do 3% of lung cancer patients have hoarseness? | Recurrent laryngeal nerve palsy |
| Horner syndrome triad | Miosis Ptosis Anhidrosis |
| Pancoast tumors are usually associated with what lung cancer type? | Squamous cell |
| Findings associated with Pancoast tumors | Superior sulcus mass involving C8 and T1-T2 nerve roots --> shoulder pain radiating down arm, upper extremity weakness, Horner syndrome |
| Prognosis if malignant pleural effusion is present | Very poor -- equivalent to distant mets |
| Types of lung cancer associated with hypertrophic pulmonary osteoarthropathy | Adenocarcinoma Squamous cell |
| Lambert-Eaton syndrome is most common in which type of lung cancer? | Small cell |
| Stability of a CXR abnormality over a _________ period is almost always associated with a benign lesion | 2-year |
| T/F: Lung cancer can be diagnosed by CXR and CT alone. | False; pathologic confirmation is necessary regardless of CXR and CT results. |
| 5-year survival for SCLC if disease is limited vs. extensive | Limited: 10-13% Extensive: 1-2% |
| Overall 5-year survival for lung cancer patients | 14% |
| NSCLC treatment options | Surgery = best option (patients with mets outside the chest are NOT candidates) Radiation = important adjunct |
| Limited SCLC treatment options | Combo of chemo and radiation |
| Extensive SCLC treatment options | Chemo alone initially If patient responds, use prophylactic radiation to decrease incidence of brain mets and prolong survival |
| Role of surgery in SCLC | Limited; most of these tumors are non-resectable |
| T/F: Most asymptomatic lung masses are benign. | True |
| Which types of lung cancer are usually central, and which are usually peripheral? | Central - squamous cell, small cell Peripheral - adenocarcinoma, large cell |
| Cavitation on CXR is associated with what type of lung cancer? | Squamous cell |
