[Exam 1/Final] Chapter 15 - Management of Patients with Oncologic Disorders Flashcards
Cancer: What is this?
Disease process that begins when abnormal cells is transformed by genetic mutations of cellular DNA
Cancer: What is metastasis?
Abnormal cells have invasive characteristics and like to infiltrate other tissues
Cancer: What are malignant cancer cells?
Demonstrate uncontrolled growth that does not follow physiologic demand
Malignant Process: What is cell prolifeation?
Uncontrolled growth with ability to metastasize and destroy tissue and cause death
Malignant Process: What are teh cell characteristics?
Presence of tumor specific antigens that trigger immune response, altered shape, structure, and metabolism
Malignant Process: What are the different types of metastasis?
Lymphatic Spread
Hematogenous Spread
Angiogenesis
Malignant Process: What is Lymphatic Spread
Lymph runs throughout body. If a cancer cell jumps in this system, will travel throughout whole body
Malignant Process: What is Hematogenous Spread
An example would be a blood vessel running through a tumor. If a piece breaks off, it will travel throughout the body
Malignant Process: What is angiogenesis
When tumors have growth of its own blood vessels. The tumor is being fed with the blood
Characteristics of Benign and Malignant Neoplasms: How will the characteristics be here?
Malignant: Cells are going to lack normal cell characteristics. Lack the proper shape and may not recognize normal cell tissue anymore.
Characteristics of Benign and Malignant Neoplasms: Mode of growth for these?
It invades the surrounding tissue for malignant. Benign , it stays within the cell
Characteristics of Benign and Malignant Neoplasms: Rate of growth for these?
In malignant, the cells grow much quicker
Characteristics of Benign and Malignant Neoplasms: Metastasis of these?
In malignant, the cells will metastasis all over the body. Other is localized
Characteristics of Benign and Malignant Neoplasms: General effects of these?
You will see inflammatory system kick in. Weight loss. Systemic changes.
Characteristics of Benign and Malignant Neoplasms: Tissue destruction of these?
This has to do with malignant growth of tissue. Destroying tissue.
Characteristics of Benign and Malignant Neoplasms: Ability to cause disease of these?
Malignant can cause other tissues to shut down as the cancer grows.
Characteristics of Benign and Malignant Neoplasms: What is the biggest thing to keep in mind with malignant?
They just grow grow grow. They ignore suppression signals. And they also contain tumor-specific antigens so they will have tumor marker on them
Carcinogenic Agents and Factors: What viruses and bacteria can cause this?
Hep B, HPV, Mono
Carcinogenic Agents and Factors: What physical factors affect this?
Sunlight, radiation, chronic irritation like having chronic GERD
Carcinogenic Agents and Factors: What chemical agents affect this?
Tobacco and Asbestos , which causes lung cancer
Carcinogenic Agents and Factors: What genetic and familal factors affect this?
Cancer will often run in family with breast or ovarian cancer. Thats why they have higher risk of breast cancer in fam. Brocco Tests can be done to test for this
Carcinogenic Agents and Factors: What diet changes this?
High alcohol, fat, and nitrates intake
Carcinogenic Agents and Factors: What hormones changes this?
Prolonged estrogen therapy.
Carcinogenic Agents and Factors: what is carcinogenesis?
This is when you have healthy cells and then you start to expose it to the carcinogens. This is a three step process
Carcinogenic Agents and Factors: What are the steps in carcinogensis?
Initiation where you are exposed to the carcinogen
Promotion , repeated exposure
Progression, where you start to have incredibly malignant behaviors so cells start to change.
Normal Immune Response: What is involved here?
Macrophages T Lymphocytes Lymphokines Interferon B Lymphocytes NK Cells
Normal Immune Response: Immune system is looking for what?
Tumor-associated antigens
Normal Immune Response: What do T Cells do?
Kill the canceer cells
Normal Immune Response: What do B cells do?
Produce antibodies
Normal Immune Response: What do NK cells do?
Attack any cells that are not supposed to be in the body
Primary and Secondary Prevention: What is primary prevention?
Concerned with reducing cancer risk in healthy people.
Avoid carcinogens, vaccines, wear sunscreen, diet.
Primary and Secondary Prevention: what is secondary prevention?
Involves detection, screening to achieve early diagnosis and intervention
Look at self-breast exam, testicular self-exam. Early detection the better.
Primary and Secondary Prevention: Big emphasis on what type?
Primary and secondary prevention. Mammograms are now included with insurance.
Primary and Secondary Prevention: What is tertiary prevention?
Preventing reoccurence and preventing developing of secondary cancers.
Diagnosis of Cancer: What is the first thing that needs to be done?
Determine presence, extent of tumor
Diagnosis of Cancer: After presence determined, what is done?
Identify possible spread (metastasis) of disease or invasion of other body tissues.
Diagnosis of Cancer: What is usually done when thinking of treatment?
Evaluate function of involved body system and obtain tissue and cells for analysis for evaluation of tumor stage.
Diagnosis of Cancer: What can be used to help diagnose?
CT , MRI, PET Scan, Draw Tumor Markers.
Keep in mind how patient is reacting to diagnosis of cancer.
Tumor Staging and Grading: What is staging?
Determines size of tumor, existence of metastasis
Tumor Staging and Grading: What is used for staging?
TNM.
Tumor Staging and Grading: What does TNM stand for?
T: Extent of primary tumor
N: Lymph node involvement
M: Extent of metastasis
Tumor Staging and Grading: What is grading?
Classification of tumor cells. Is the tissue well-differentiated, does it look like liver tissue is supposed to?
Tumor Staging and Grading: What is the grading system?
1-4 system. 1 resembles normal tissue while 4 does not resemble it at all.
Cancer Mx: This is aimed at what?
Cure
Control
Palliation
Cancer Mx: What is cure?
Complete eradication of the disease
