SM_183a: Lung Cancer Flashcards
Lung cancer is the _____ cause of cancer related deaths
Lung cancer is the leading cause of cancer related deaths
(not the most common cancer)
Most lung cancer patients present with ______ disease
Most lung cancer patients present with advanced disease
The greatest risk factor for lung cancer is _______
The greatest risk factor for lung cancer is tobacco
(mostly smoking, but also second hand smoke)
Patients with early stage lung cancer are often ______
Patients with early stage lung cancer are often asymptomatic
(often found incidentally or through lung cancer screening)
(may have a cough, hemoptysis, or dyspnea)
_______ is the classic radiographic finding of lung cancer
Coil lesion is the classic radiographic finding of lung cancer
(but lung cancer can look like anything)
Describe the presenting signs and symptoms of lung cancer
- Often asymptomatic
- Cough
- Weight loss
- Dyspnea
- Chest pain
- Hemoptysis
Lung tumors can cause _____, _____, or _____ in advanced disease
Lung tumors can cause superior vena cava syndrome, nerve impingement, or hoarseness in advanced disease
Superior vena cava syndrome occurs when ______
Superior vena cava syndrome occurs when SVC is obstructed, leading to vessel obstruction
Symptoms of superior vena cava syndrome include ______, ______, ______, and ______
Symptoms of superior vena cava syndrome include facial plethora, dilated collateral veins along chest, extremity edema, and headaches
Pancoast tumor is a(n) _____ tumor causing _____, with symptoms of ______, ______, or ______
Pancoast tumor is an apical tumor causing nerve impingement, with symptoms of shoulder pain, brachial plexus, and Horner’s syndrome
Horner’s syndrome is caused by a ______ tumor and involves symptoms of ______, ______, and ______
Horner’s syndrome is caused by a pancoast tumor and involves symptoms of constricted pupil (miosis), drooping of upper eyelid (ptosis), and absence of sweating of the face (anhidrosis)
(sympathetic nerve constricted)
Pancoast tumor can cause hoarseness if _____ is compressed
Pancoast tumor can cause hoarseness if laryngeal nerve is compressed
What are the most common sites of lung cancer metastases?
Pleura, brain, bone, adrenal, and liver
______ is redness of the face after lifting arms and is associated with _____ secondary to lung tumor
Pemberton’s sign is is redness of the face after lifting arms and is associated with superior vena cava syndrome secondary to lung tumor
_____ is required to make a diagnosis of lung cancer
Tissue sampling is required to make a diagnosis of lung cancer
(if metastatic disease is suspected, a biopsy of a distant site is preferred because it confirms both the diagnosis and the stage)
- Histology: cell type
- Molecular analysis: what is driving cell to grow
- PDL1 analysis: interaction between tumor and immune system
Describe adenocarcinoma
Adenocarcinoma
- Most frequent histology in non-small cell lung cancer
- Derived from gland cells
- Biopsy: glandular structures
- Central or peripheral tumors
- Seen in non-smokers and smokers
Describe squamous cell carcinoma
Squamous cell carcinoma
- 2nd most common type of non-small cell lung cancer
- Occurs in smokers
- Central tumors, near hilum, cavitary lesions
- Paraneoplastic syndrome: PTHrp -> hypercalcemia
- Biopsy: keratin pearls
Describe small cell lung cancer
Small cell lung cancer
- Aggressive tumors (poor prognosis)
- Neuroendocrine tumor
- Occurs in smokers
- Central tumors
- Biopsy: small, densely packed blue cells
- Associated with paraneoplastic syndromes
