Oral Cancers
Premalignant Leukoplakia |
most common in adults, most often see in men
Slow developing changes in the oral mucousa Thick, white, firmly attached, slightly raised and sharply circumscribed patches (can not be removed by scraping) Small percentage become malignant after about 8 years Lesions on lips and tongue most likely to become malignant Causes Long term irritation to the oral membranes Poorly fitting dentures Chronic cheek chewing Broken teeth HIV infection Tobacco use |
|
Oral Cancers
Premalignant Erythroplakia |
Red, velvety mucosal lesion on oral mucosa
More likely to become malignant Usually seen on the floor of the mouth, tongue, palate and mandibular mucosa |
|
Oral Cancers
Malignant Tumors Squamous Cell Carcinoma |
Most common of the oral cancers
Usually found on lips, tongue, buccal mucosa, oropharynx Occurs because over many years cell changes take place in the oral cavity Early symptom is mucosal erythroplasia (lesions that are red, raised, and eroded) Risk factors Increasing age Tobacco Alcohol ingestion (combination with tobacco increases risk) Textile workers, plumbers, coal and metal workers Sun exposure Poor oral hygiene Poor dietary habits Human papillomavirus (HPV16) |
|
Oral Cancers
Malignant Tumors Basal Cell Carcinoma |
Usually occurs on the lips
Asymptomatic, doesn’t usually spread Starts with a small scabbed area that does not heal and advances to an ulcerated area with a pearly border High risk factor is sun exposure Prevention Important Screening by dentist yearly Decrease sun exposure/wear SPF Stop tobacco use Decrease alcohol consumption |
|
Oral Cancers
Malignant Tumors Basal Cell Carcinoma Clinical Manifestations |
Unusual lumps or thickened areas
Red or white patches Sore that does not heal Soreness, pain, burning sensation Trouble swallowing or chewing Pain may radiate to ear Enlarged lymph nodes |
|
Oral Cancers
Malignant Tumors Basal Cell Carcinoma Diagnosis |
History/Physical exam
CT scan/MRI Biopsy-definitive Toluidine blue solution for high risk persons-may have false positive (if solution turns blue it indicates cancer) results with inflammation |
|
Oral Cancers
Malignant Tumors Basal Cell Carcinoma Interventions |
Airway is the priority
Assess breath sounds, oxygen saturation levels, respiratory rate Clear secretions-cough, suction Semi-fowler’s/high fowler’s position Prevent aspiration May need a trach |
|
Oral Cancers
Malignant Tumors Basal Cell Carcinoma Non-surgical Treatment |
Good oral care
Q 2 hours No commercial or harsh mouthwash (use warm saline or baking soda) Soft bristle toothbrush Lubricant to lips Soft, bland, non-acidic foods Radiation Goal-get rid of the tumor while preserving function and appearance May be given alone or with chemo or surgery Can be given externally or internally Chemotherapy May be given alone or with radiation or surgery May receive more than one chemo agent |
|
Oral Cancers
Malignant Tumors Basal Cell Carcinoma Surgical treatments |
Type of surgery depends on the size, location of lesion, spread into the bone and lymph nodes
If small enough can be removed under a local anesthesia More extensive lesions may require a partial or total glossectomy (tongue removal) and partial mandibulectomy with radical neck dissection |
|
Oral Cancers
Malignant Tumors Basal Cell Carcinoma Pre-op and Post-op care |
Preoperative care
Make sure patient understands what procedure is planned Possibility of trach, drains, IVs, ICU placement Changes with speech NPO Routine post op care-T, C, DB, out of bed Post operative care Airway, airway, airway Prevention of infection-good oral care, antibiotics, assessment Elevate HOB at least 30 degrees-prevents edema, prevents aspiration Pain control Nutrition-NPO with TPN/tube feedings, assess for trouble swallowing |
|

Pallitive treatment if surgery not an option
Photofrin (a drug) is given that goes to cancer cells, light from a fiberoptic source activates the med and destroys the cancer cells Esophageal Dilation Provides temporary but immediate relieve from dysphagia. May be repeated as needed Stents may be used to keep the esophagus open Recommended use of prophylactic antibiotics to decrease the risk of endocarditis |
|

|
Esophageal cancer
post-operative care |
Prevent pulmonary complications (highest priority)
Intubated/on ventilator T, C, DB Assess breath sounds Medicate for pain Elevate HOB Assess O2 sats Check chest tube functioning (if in place) Prevent cardiovascular complications Monitor for hypotension-adm IV fluids Assess for fluid overload Cardiac monitor-watch for atrial fibrillation |
|

NG tube care |
Monitor drainage for color and amount
Do not reposition-very important |
|
Esophageal cancer
Nutrition |
Usually start via jejunostomy tube
Liquid diet advancing to solid food-need to be sure that there is no leakage at the surgical site-done with cine-esophagram study Should eat in an upright position Monitor swallowing efforts for aspiration Eat six small feedings instead of 3 large meals Ingest fluids separate from eating solids Vagotomy syndrome-diarrhea that occurs as a result of interruption of the vagal nerve during the surgical procedure. Manage with loperamide (Imodium) |

|
Second leading cause of cancer death in world
5 year survival rate is low Cancer is usually advanced by the time of detection |
|
Gastric Cancer
Pathophysiology |
Most gastric cancers are adenocarcinoma and will be either intestinal (contained) or diffuse (scattered).
Gastric cancers usually spread through the wall of the stomach into the lymphatic system |
|
Gastric Cancer
Causes |
Presence of H. Pylori bacteria due to chronic inflammation
Increased risk with pernicous anemia, gastric polyps, chronic gastritis, achlorhydria (no hydrochloric acid) Increased risk with ingestion of certain foods (salt, nitrates) Smoking and increased alcohol use (controversial) Family history Previous gastric surgery (increased risk of developing gastritis) |
|

Prevention |
Get rid of H. pylori bacteria
Make sure gastritis heals No smoking Limit alcohol Consume well balanced diet Genetic counseling with family history |
|

Diagnosis |
History
H. pylori Food intake Family history Smoking/alcohol use Diagnostic Tests Low hemoglobin and hematocrit Stool positive for occult blood Elevated CEA, usually only seen in infants, in adults may indicate cancer Double contrast upper GI series-done first CT scan to stage the disease and see extent of spreading EGD (esophagogastroduodenoscopy)-definitive |
|

Often metastasis to liver Can be screened for |
|
Colorectal Cancer
Pathophysiology |
Adenocarcinomas are the most common (tumors that develop from the glandular epithelial tissue of the colon)
They usually develop slowly over many years Initially start in the mucosa and takes a long time to spread through the layers of the stomach to get into the lymphatic system |
|
