  1. Para-tracheal
    are all lymph nodes of ________________
    Mediastinal Lymph Nodes

    Involvement of mediastinal lymph nodes is common in primary lung cancers
  2. List 4 etiologic factors for lung cancers
    • smoking
    • asbestos
    • atmospheric pollution
    • arsenic
    • nickel exposure
    • previous thorax radiation
    • exposure to ether
    • chronic obstructive pulmonary disease

    The strongest risk factor for the development of lung cancer continues to be cigarette smoking
  3. briefly explain the situation in which high dose rate (HDR) brachytherapy would be an appropriate management for lung cancer.
    HDR for brachytherapy for the management of lung cancer is delivered endobronchial.  patients who have tumors located in or near the main stems bronchus might benefit from endobronchial HDR brachytherapy
  4. Clubbing of the fingers is one physical symptom of _______________.
    Chronic obstructive pulmonary disease. 

    Clubbing of the fingers is a symptom of COPD or other diseases of the heart or lungs where there is a decrease blood oxygen level
  5. A patient with a middle lobe posterior lung tumor may be positioned prone to facilitate
    easier alignment of off-cord oblique's and boost fields directly posterior.

    A posteriorly located lung tumor may be easily treated during the boost portion of radiation therapy by using a single posterior field or posterior oblique fields
  6. Total dose for prophylactic cranial irradiation is typically
    3600 cGy

    Dose for prophylactic radiation to the brain is typically 36-40 Gy
  7. How many lobes does the right lung have?
  8. The histologic type of lung cancer most closely associated with asbestos exposure is
  9. A radiation treatment field with an upper border above both clavicles and lower border approximately 5 cm below the carina, including mediastinal lymphatic's and blocking most of the left lung would likely be
    an initial field for treatment of an upper lobe right lung tumor
  10. Define Odynophagia:
    painful swallowing

    The proximity of the bronchus to the esophagus and the potential for mediastinal lymphadenopathy may cause a patient with diagnosed lung cancer to experience pain when swallowing food
  11. Define Hemoptysis
    coughing up blood

    Bronchial tumors may begin to break up with persistent coughing and produce bloody sputum.
  12. Define

    Difficulty breathing

    Patients with lung tumors and/or positive mediastinal disease may experience difficulty breathing
  13. Define Atelectasis
    Collapse of the lung

    The location or persistence of a lung tumor or chronic obstructive conditions of the lung may lead to collapse of the lung
  14. This type of lung cancer tends to be located near the periphery of the lung
  15. This type of lung cancer tend to be proximal
    and involve the hilum.
    Will likely grown into the bronchial lumen & cause associated pneumonitis
    Squamous Cell Carcinoma
  16. this type of lung cancer is located in the apex of the lung 
  17. This type of lung cancer manifest in the lung pleura
  18. This type of lung cancer shows up similar to adenocarcinoma
    Large Cell Carcinoma
  19. This histologic type of lung cancer seen in patients wit no history of smoking is
  20. This histologic type is assumed to indicate that there is already distant disease at the time of diagnosis is
    Oat Cell Carcinoma
  21. Initial AP/PA fields the lung cancer may require an anterior wedge to:
    Compensate for the natural slope of the chest
  22. To verify the histology of a suspected lung cancer a ___________ is helpful
    ct scan
  23. Target Volume delineation for lung tumors may involve cardiac or respiratory gating procedures.
    The rationale for this is that lung tumors ____________________________ 
    move with cardiac and respiratory motion
  24. The natural slope of the chest may cause high dose regions in the upper mediastinum.
    This area of increased dose may be managed by the use of the ___________________
    Custom compensator
