Question | Answer |
What is the leading cancer killer of women and men? | Lung |
Most aggressive type of lung cancer. Not surgically treated. Highest rate of mets. Usually systemic disease = | Small cell lung ca (16% of lung cancers) |
Most common type of lung cancer | non-small cell (85%) |
Most common types of non-small cell lung cancer | Squamous cell (30-35%), adenocarcinoma (30-35%), large cell (3-5%) |
Squamous cell lung cancer usually originates where in the lung? | central |
Adenocarcinoma lung cancer usually originates where in the lung? | peripheral |
What is the presentation of stage 1 lung cancer? | Predominately asymptomatic (while more advanced is symptomatic) |
What fraction of patients present to PCP with stage 3-4 lung cancer? | 2/3 |
Most frequent symptoms associated with advanced lung cancer | Cough, wt loss, dyspnea, chest pain, hemoptosis, bone pain, lymphadenopathy, hepatomegaly, clubbing, horseness, SVC syndrome |
In which population is there an increasing incidence in lung cancer? | Young, white, non-smoking females |
What is the most common cause of death in lung cancer? | distant metastases |
Which stages of lung cancer are resectable? | stages I-IIIa |
Initial imaging modality for suspicion of lung cancer | chest x-ray |
A __ lesion on chest x-ray is considered malignant until proven otherwise | non-calcified |
RFs for lung cancer include: | smoking, air pollution, ionizing radiation, asbestosis, heavy metals,industrial carcinogens |
Most common etiologic factor in lung cancer: | smoking (85% of cases overall M>F) |
Imaging used to evaluate for mets: | PET, brain CT, MRI |
Imaging modality considered the standard of care in proper staging of lung tumors | Bronchoscopy |
Gold standard for lymph node evaluation with lung cancer = | cervical mediastinoscopy |
Lung cancer type more easily detected early: | SCLC (in sputum) - bc it often originates in central bronchi |
Tends to be glandular & mucus-producing; associated with pleural effusions = | adenocarcinoma |
In lung cancer, local mets may cause symptoms associated with what anatomic area? | Mediastinal structures (phrenic nerve, SVC, recurrent laryngeal nerve) |
Common distant mets sites in lung cancer: | bone, brain, adrenals, kidney, liver |
Lung cancer is often associated with paraneoplastic syndromes grouped as: | endocrine, systemic, neuro, cutaneous, hematologic, renal |
Lung ca workup | CXR, CT, CBC, LFTs, lytes, Ca. Bronchoscopy; sputum cyto & pleural fluid; LN bx |
5 year survival rate for SCLC & NSCLC = | NSCLC = 15%. Limited-stage SCLC = 7%; extensive-stage dz = 1% |
What % of mediastinal masses, originating in mediastinum, are benign? | 75% |
Most common anterior mediastinal mass = | thymoma |
Anterior mediastinal mass DDx | Thymoma, lymphoma, thyroid/PT, teratoma (germ cell tumor) |
Middle mediastinal mass DDx | Hiatal hernia & mets cancer most common; also sarcoid, AAA, pericardial cyst (most common mediastinal cyst), bronchogenic cyst, LAD |
Posterior mediastinal mass DDx | Neurogenic tumor (20% of all primary mediastinal tumors) |
50% of patients with thymoma initially present with: | myasthenia gravis |
Complications of lung cancer (SPHERE) | SVC syndrome, Pancoast tumor, Horner syndrome, Endocrine (carcinoid), Recurrent laryngeal nerve (hoarseness), Effusions |
Common endocrine syndrome/effect of SCLC | Cushing/SIADH |
Common endocrine syndrome/effect of SCC | Hypercalcemia/PTH dz |
Common endocrine syndrome/effect of large cell lung cancer | Gynecomastia |
Common endocrine syndrome/effect of adenocarcinoma | thrombophlebitis |
