Characteristics of Neoplasia

Uncontrolled growth of Abnormal cells

1. Benign

2. Malignant

3. Borderline


BENIGN

Well-differentiated

Slow growth

Encapsulated

Non-invasive

Does NOT metastasize


MALIGNANT

Undifferentiated

Erratic and Uncontrolled Growth

Expansive and Invasive

Secretes abnormal proteins

METASTASIZES

Nomenclature of Neoplasia

Tumor is named according to:

1. Parenchyma, Organ or Cell

Hepatoma- liver

Osteoma- bone

Myoma- muscle



2. Pattern and Structure, either GROSS or MICROSCOPIC

Fluid-filled CYST

Glandular ADENO

Finger-like PAPILLO

Stalk POLYP



3. Embryonic origin

Ectoderm ( usually gives rise to epithelium)

Endoderm (usually gives rise to glands)

Mesoderm (usually gives rise to Connective tissues)

BENIGN TUMORS

Suffix- “OMA” is used

Adipose tissue- LipOMA

Bone- osteOMA

Muscle- myOMA

Blood vessels- angiOMA

Fibrous tissue- fibrOMA

MALIGNANT TUMOR

Named according to embryonic cell origin

1. Ectodermal, Endodermal, Glandular, Epithelial

Use the suffix- “CARCINOMA”

Pancreatic AdenoCarcinoma

Squamos cell Carcinoma

MALIGNANT TUMOR

Named according to embryonic cell origin

2. Mesodermal, connective tissue origin

Use the suffix “SARCOMA

FibroSarcoma

Myosarcoma

AngioSarcoma

“PASAWAY”

1. “OMA” but MalignantHepatOMA, lymphOMA, gliOMA,

melanOMA

2. THREE germ layers “TERATOMA”

3. Non-neoplastic but “OMA”ChoristomaHamatoma

CANCER NURSING

Review of Normal Cell Cycle

3 types of cells

1. PERMANENT cells- out of the cell cycle Neurons, cardiac muscle cell

2. STABLE cells- Dormant/Resting (G0) Liver, kidney

3. LABILE cells- continuously dividing GIT cells, Skin, endometrium , Blood cells

CANCER NURSING

Cell Cycle

G0------------------G1SG2M

G0- Dormant or resting

G1- normal cell activities

S- DNA Synthesis

G2- pre-mitotic, synthesis of proteins for cellular division

M- Mitotic phase (I-P-M-A-T)

CANCER NURSING

Proposed Molecular cause of CANCER:

Change in the DNA structure altered DNA function Cellular aberration

cellular death

neoplastic change

Genes in the DNA- “proto-oncogene” And “anti-oncogene”

1. LYMPHATICMost common

2. HEMATOGENOUSBlood-borne, commonly to Liver and Lungs

3. DIRECT SPREADSeeding of tumors

CANCER NURSING

Body Defenses Against TUMOR

1. T cell System/ Cellular ImmunityCytotoxic T cells kill tumor cells

2. B cell System/ Humoral immunityB cells can produce antibody

3. Phagocytic cellsMacrophages can engulf cancer cell debris

Cancer Diagnosis

1. BIOPSY The most definitive

2. CT, MRI

3. Tumor Markers

CANCER NURSING

Cancer Grading

The degree of DIFFERENTIATION

Grade 1- Low grade

Nursing Assessment

Utilize the ACS 7 Warning SignalsCAUTIONC- Change in bowel/bladder habitsA- A sore that does not healU- Unusual bleedingT- Thickening or lump in the breastI- IndigestionO- Obvious change in wartsN- Nagging cough and hoarseness

Nursing Assessment

Weight loss

Frequent infection

Skin problems

Pain

Hair Loss

Fatigue

Disturbance in body image/ depression

Nursing Intervention

MAINTAIN TISSUE INTEGRITY

Handle skin gently

Do NOT rub affected area

Lotion may be applied

Wash skin only with SOAP and Water

Nursing Intervention

MANAGEMENT OF STOMATITIS

Use soft-bristled toothbrush

Oral rinses with saline gargles/ tap water

Avoid ALCOHOL-based rinses

Nursing Intervention MANAGEMENT OF ALOPECIA

Alopecia begins within 2 weeks of therapy Regrowth within 8 weeks of termination Encourage to acquire wig before hair loss

occurs Encourage use of attractive scarves and hats Provide information that hair loss is

temporary BUT anticipate change in texture and color

Nursing Intervention PROMOTE NUTRITION Serve food in ways to make it appealing Consider patient’s preferences Provide small frequent meals Avoids giving fluids while eating Oral hygiene PRIOR to mealtime Vitamin supplements

Nursing Intervention RELIEVE PAIN Mild pain- NSAIDS

Moderate pain- Weak opiods Severe pain- Morphine Administer analgesics round the clock

with additional dose for breakthrough pain

Nursing Intervention DECREASE FATIGUE Plan daily activities to allow alternating

rest periods Light exercise is encouraged Small frequent meals

Nursing Intervention IMPROVE BODY IMAGE Therapeutic communication is essential Encourage independence in self-care

and decision making Offer cosmetic material like make-up

and wigs

Nursing Intervention ASSIST IN THE GRIEVING PROCESS Some cancers are curable Grieving can be due to loss of health,

income, sexuality, and body image Answer and clarify information about

cancer and treatment options Identify resource people Refer to support groups

Nursing Intervention MANAGE COMPLICATION: INFECTION Fever is the most important sign (38.3) Administer prescribed antibiotics X 2weeks Maintain aseptic technique Avoid exposure to crowds Avoid giving fresh fruits and veggie Handwashing Avoid frequent invasive procedures

Nursing Intervention MANAGE COMPLICATION: Septic

shock Monitor VS, BP, temp Administer IV antibiotics Administer supplemental O2

Nursing Intervention MANAGE COMPLICATION: Bleeding Thrombocytopenia (<100,000) is the

most common cause <20, 000 spontaneous bleeding Use soft toothbrush Use electric razor Avoid frequent IM, IV, rectal and

catheterization Soft foods and stool softeners

Colon cancer

NURSING INTERVENTION

Pre-Operative care

1. Provide HIGH protein, HIGH calorie and LOW residue diet

2.Provide information about post-op care and stoma care

3. Administer antibiotics 1 day prior

Colon cancer


Pre-Operative care

4. Enema or colonic irrigation the evening and the morning of surgery

5. NGT is inserted to prevent distention

6. Monitor UO, F and E, Abdomen PE

Colon cancer

NURSING INTERVENTIONPost-Operative care

1. Monitor for complicationsLeakage from the site, prolapse of stoma, skin irritation and pulmo complication2. Assess the abdomen for return of peristalsis

Colon cancer

NURSING INTERVENTIONPost-Operative care

3. Assess wound dressing for bleeding4. Assist patient in ambulation after 24H5.provide nutritional teachingLimit foods that cause gas-formation and odorCabbage, beans, eggs, fish, peanutsLow-fiber diet in the early stage of recovery

Colon cancer


Post-Operative care

6. Instruct to splint the incision and administer pain meds before exercise

7. The stoma is PINKISH to cherry red, Slightly edematous with minimal pinkish drainage

8. Manage post-operative complication

Colon cancer

NURSING INTERVENTION: COLOSTOMY CARE

Colostomy begins to function 3-6 days after surgery

The drainage maybe soft/mushy or semi-solid depending on the site

Colon cancer

NURSING INTERVENTION: COLOSTOMY CAREBEST time to do skin care is after showerApply tape to the sides of the pouch before showerAssume a sitting or standing position in changing the pouch

Colon cancer

NURSING INTERVENTION: COLOSTOMY CAREInstruct to GENTLY push the skin down and the pouch pulling UPWash the peri-stomal area with soap and waterCover the stoma while washing the peri-stomal area

Colon cancer


Lightly pat dry the area and NEVER rub

Lightly dust the peri-stomal area with nystatin powder

Colon cancer


Measure the stomal opening

The pouch opening is about 0.3 cm larger than the stomal opening

Apply adhesive surface over the stoma and press for 30 seconds

Colon cancer


Empty the pouch or change the pouch when1/3 to ¼ full (Brunner)½ to 1/3 full (Kozier)
