Med-Surg: Chapter 26: Lung Cancer Flashcards
Epidemiology
- second most common cancer in both men and women
- number one cancer killer in the US for both men and woman
- survival rates based on the stage of the disease
- major cause and most preventable is smoking
Pathophysiology
the uncontrolled growth of abnormal cells in the lungs causes lung cancer
Two types of Lung Cancer
- non-small cell
- small cell
Non-small cell cancer
-represents 85% of lung cancers >consists of 3 types of cells: -squamous-cell carcinoma -adenocarcinoma -large-cell carcinoma
Small-cell cancer
“oat-cell” cancer
- represents 15% of lung cancer
- grows quickly and metastasizes to other organs in the body
- survival statistics poor
Diagnosis
- Chest x-ray
- Computed tomography (CT) scan of the chest
- Sputum for cytology
- Bronchoscopy
- Positron Emission tomography (PET) scans
- Bone scans and Abdominal scans
- Mediastinoscopy
What would a chest x-ray or CT scan show?
-a pulmonary lesion
What would a cytology test on sputum identify?
-specific tumor cells
Bronchoscopy
allows direct visualization of the tissues to aid in diagnosis
-is the assessment of the larger airways, the trachea and bronchi, through a scope inserted through the mouth or nose
Mediastinoscopy
allows direct visualization of the tissues to aid in diagnosis
- surgical procedure that allows for direct visualization of the mediastinum
- a scope is inserted through an incision in the chest that allows direct examination and collection of samples for biopsy
Why are Bone scans and Abdominal scans performed?
to look for metastatic lesions
Positron Emission Tomography (PET) scans
used to identify change’s in the body’s metabolism and function rather than structure
-PET scan can detect areas of increased metabolic activity as occurs with rapidly dividing cancer cells
Treatment for Lung Cancer is Based on?
is interprofessional and is dependent on the type, size, location, and stage of the tumor
Non-surgical Treatments
- combination of radiation and chemotherapy
- pain management
Non-Surgical Treatment: Chemotherapeutic Agent
the chemotherapeutic agent used to treat lung cancer is dependent on the type and/or size of the tumor
- may be used in conjunction with surgery
- may be the primary treatment option for more advanced cancers or if the patient is too ill for surgery
