most primary Lung caner arises from
|
bronchial epithelium:
-abnormal cells form from exposure to carcinogen -Infiltrate tissue, node, and can metastasize |
|
|
survival rate of Lung cancer
|
14-16% #1 killer re; cancer
|
|
|
non-small cell cancer
|
(NSCLC)
-Epidermoid/ squamous -giant/large cell -Adenocarcinoma |
|
|
Most common in non smokers
|
Adenocarcinoma
is the most common type of lung cancer. It accounts for 30-40% of lung cancers. It may have no clinical manifestations until there is wide-spread metastasis. |
|
|
Squamous cell carcinomas
|
is the second most common type of lung cancer. It accounts for about 30% of lung cancer and is more common in men. It is a slow-growing cancer, and usually begins in the bronchial tubes. It does not have a strong tendency to metastasis.
|
|
|
Large cell carcinomas
|
is the least common type of lung cancer, it accounts for about 5-15%. for non small cell lung cancer, it is usually treated surgically. Large cell carcinomas does not always have surgery because of the high rate of metastasis
|

|
|
Small cell lung cancer
|
is almost always associated with cigarette smoking. It accounts for about 20% of lung cancers and is the most malignant form. It tends to spread early, and quickly. Chemotherapy is the treatment for this type of cancer. The patient does have a poor prognosis however. Radiation will be used as an adjuvant therapy. Radiation may also be used as a palliative measure.

Superior Vena Cava syndrome
|
Superior Vena Cava is compressed or obstructed by a tumor growth
can block blood flow to head neck upper trunk |
|
|
Superior Vena Cava syndrome early s/s
Superior Vena Cava syndrome late s/s |
edema especially in eyes when waking tightness in shirt collar (stokes syndrome)
edema of arms hands, dyspnea, erthyma, epistaxis (nosebleeds) |
