Unit 22 Altered Cell Proliferation: Solid Tumors Flashcards
What is considered a low ANC (absolute neutrophil count)?
What can this be an indication of?
ANC less than 500 is critical
Can be indication of the need to reduce chemo dosage or delay of next therapy
Describe colorectal cancer.
3rd most common cancer is US
Rare before age of 30
Early dx = great prognosis
Late dx = poor prognosis
What are general, lifestyle, and genetic risk factors for Colon Cancer?
General:
- Age
- DM2
- IBD
- Polyps
Lifestyle:
- Inactivity
- ETOH
- Tobacco
- Poor diet
Genetics:
- Family hx
- Inherited (HN gene, FAP gene- full of polyps, by age 40 most likely to develop cancer)
What are Colorectal Cancer manifestations?
Local:
- Changes in stool (blood, shape, frequency, “melena stool”
- Abdominal fullness
- Symptoms of obstruction (constipation, hard stools)
Systemic:
- Weight loss (tumor increases metabolism
- N/V
- Weakness
- Anemia (from bleeding, fatigue presents)
What are Colorectal Cancer Diagnostic Labs?
Stool for guiac/ occult blood
CBC - to check for anemia
LFT (liver function tests)
CEA (carcino embryonic antigen):
- Commonly used to monitor PT’s for effectiveness of Rx
- Level should be 0
- Indicates if there is cancer
- If tumor removed CEA level should drop
What are Colorectal Cancer Diagnostic Radiology procedures?
CT scan
Colonoscopy/sigmoidoscopy
Double contrast barium enema w/X-ray
What is the surgical collaborative management of Colorectal cancer?
How does the nurse prep the PT before these procedures?
After colectomy what should the nurse assess?
-Colon resection with or w/o colostomy
-R hemicolectomy (remove right portion of colon, small intestine to transverse colon)
-L hemicolectomy
(removed left portion of colon, transverse to sigmoid
-Total colectomy
-Abdomino-perineal resection
(assess for pain and bleeding post-procedure)
PT NPO
No food coloring or meat before
Go Lyte-ly (solution to clear bowels)
Bowel sounds
What is stomatitis?
Alteration in oral mucosa secondary to radiation, inflammation of the oral tissuesama
What is the medical collaborative management of Colorectal Cancer?
Chemotherapy:
- Antimetabolites (5-FU)
- Tumor profiling to treat w/ most effective Chemo
Biotherapy:
-Monoclonal antibodies (bevacizumab)
Radiation:
-Cyberknife
What is a sign of left sided colorectal cancer?
Narrow stools
What is the most common treatment for colorectal cancer?
Surgical resection
What is adjuvant care?
Give example.
Additional treatment
Ex: Chemo if lymph node involvement or metastasis
- 5-FU with leucovorin and oxaliplatin
- radiation before or after sx
What is the most common site of metastasis colorectal colon cancer?
Liver
What is the nursing colostomy care?
Assess stoma every 8 hrs, should be red/shiny
Cleanse skin and apply skin barrier
Record volume, color, and consistency of stool
Mild edema and bleeding are normal,
Moderate to severe edema and bleeding are not
Teach ostomy self-care
What can an increase in CEA (carcinoembryonic antigen) indicate?
Cancer has returned or metastasized
Describe the Prostate/Prostate Cancer.
- Prostate needs male hormones like testosterone to grow.
- Located under the bladder
Most prostate cancer is acquired
Most common occurring cancer in men
Second leading cause of death among men
What are Prostate Cancer Risk factors?
Advancing age
Family hx
Genetics (BRCA-2 gene)
Race/ethnicity
Lifestyle (poor diet, STD’s, smoking, etc)
