  • Slide 1 - 13/12/2010 1 Brain CancerColon Cancer Dr Ibraheem Bashayreh, RN, PhD
  • Slide 2 - 13/12/2010 2 Significance The brain is the center of thoughts, emotions, memory and speech. Brain also control muscle movements and interpretation of sensory information (sight, sound, touch, taste, pain etc)
  • Slide 3 - 13/12/2010 3 Background Estimated 18,400 primary malignant brain tumors will be diagnosed in 2004 —10,540 in men & 7,860 in women. Approximately 12,690 people will die from these tumors in 2004. Accounts for 1.4% of all cancers Accounts for 2.4% of all cancer related deaths
  • Slide 4 - 13/12/2010 4 Brain tumor an abnormal growth of cells within the brain or inside the skull which can be cancerous or non-cancerous (benign) It is defined as any intracranial tumor created by abnormal and uncontrolled cell division, normally either - in the brain itself (neurons, glial cells (astrocytes, oligodendrocytes, ependymal cells), lymphatic tissue, blood vessels), - in the cranial nerves (myelin-producing Schwann cells), - in the brain envelopes (meninges), skull, pituitary and pineal gland, - or metastatic tumors
  • Slide 5 - 13/12/2010 5 Brain tumor Primary (true) brain tumors are commonly located in the - posterior cranial fossa in children - anterior 2/3 of the cerebral hemispheres in adults, although they can affect any part of the brain.
  • Slide 6 - 13/12/2010 6 Risk Factors * Most brain cancers happen for reasons unknown, however some small risk factors are * Environmentsl risk factor Smoking Diet Occupation Mobile phone Radiation exposure Exposure to vinyl chloride * Immunosupression - * Linked with Genetic abnormalities -
  • Slide 7 - 13/12/2010 7 Brain tumor Tumors can effect any part of the brain and depending on what part(s) of the brain it affects can have a number of symptoms. Seizures Difficulty with language Mood changes Change of personality Changes in vision, hearing, and sensation. Difficulty with muscle movement Difficulty with coordination control
  • Slide 8 - 13/12/2010 8 WHO CLASSIFICATION
  • Slide 9 - 13/12/2010 9 GLIOMA a type of tumor that starts in the brain or spine. It is called a glioma because it arises from glial cells The most common site of gliomas is the brain occurs in adults over 45 years of age 90% of all brain tumors are Gliomas Classification Classified - by cell type, - by grade, - by location.
  • Slide 10 - 13/12/2010 10 By cell type
  • Slide 11 - 13/12/2010 11 Astrocytoma Astrocytes brain cells abnormally dividing causing tumors called astrocytomas. Astrocytes are glial cells that help nourish neurons– they help repair damage How the astroytomas are classified How close the cells are together within the tumor How abnormal the cells are How many of the cells are proliferating Whether or not there are blood vessels growing near the tumor Whether or not some of the cancer cells have degenerated or not
  • Slide 12 - 13/12/2010 12 Astrocytomas--Treatments If tumors have not infiltrated normal brain tissue then surgery can be a cure Low-grade Astrocytomas are not curable by surgery. However through surgery as much of the tumor as possible is removed and then the patient usually goes through radiation treatment.
  • Slide 13 - 13/12/2010 13 Astrocytomas--Treatment High-grade Astrocytomas are not curable by surgery. After surgery has removed as much of the tumor as possible the patient can go through radiation treatment and chemotherapy. Most common drug given to these patients after chemotherapy is BCNU (Carmustine)
  • Slide 14 - 13/12/2010 14 Oligodendrogliomas These tumors start in mutated oligodendrocyte brain cells Oligodendrocytes make myelin which help neurons transmit signals through the axons These tumors may spread through cerebrospinal fluid pathways but typically do not usually spread to locations outside of the brain or spinal cord.
  • Slide 15 - 13/12/2010 15 Oligodendrogliomas--Treatments Because these tumors infiltrate normal brain tissue these tumors are not cured through surgery. However removal of part of the tumors can relieve some symptoms and prolong life. If the tumor is causing disabilities to the patient after surgery the patient may go through chemotherapy, perhaps followed by radiation treatments.
  • Slide 16 - 13/12/2010 16 Ependymomas Mutated ependymal cells Ependymal cells line the ventricles in the central area of the brain and they line part of the pathway through which the cerebrospinal fluid travels Theses mutated cells may block the cerebrospinal fluid from exiting the ventricles causing the ventricles to enlarge (hydrocephalus)
  • Slide 17 - 13/12/2010 17 Ependymomas--Treatments These tumors do not usually infiltrate normal brain tissue and are therefore curable through surgery. If surgery is unable to completely remove the tumors the patient may try radiation therapy.
  • Slide 18 - 13/12/2010 18 Diagnosis These tumors can be detected through a MRI, CT scan or a PET scan (Positron emission tomography is a nuclear medicine imaging technique which produces a three-dimensional image or picture of functional processes in the body. Once detected, depending on where the tumor is located, a biopsy officially is used to diagnosis cancer.
  • Slide 19 - 13/12/2010 19 Prognosis For people ages 15-44 five year survival rate is 55% For people ages 45-64 five year survival rate is 16% For people over 65 five year survival rate is 5%
  • Slide 20 - 13/12/2010 20 Colon Cancer
  • Slide 21 - 13/12/2010 21 What is the Colon The Colon comprises the end of the long, coiled, tubular digestive tract located in the Abdomen It basically acts as a waste processor Takes digested food in the form of Solid waste pushing it out of the rectum and anus The Colorectal tube is a prime location for the development and growth of small polyps or tumors
  • Slide 22 - 13/12/2010 22 Colon; The Cancer Its Self It starts with a simple cell the mutates and grows into a polyps If a polyp is allowed to remain in the colon it can grow into a cancerous tumor that can invade other organs. Colon cancer is the second leading cause of cancer deaths
  • Slide 23 - 13/12/2010 23 Colon cancer Sigmoid colon is the most common site Predominantly adenocarcinoma If early 90% survival 34 % diagnosed early 66% late diagnosis
  • Slide 24 - 13/12/2010 24 Colon cancer PATHOPHYSIOLOGY Benign neoplasm DNA alteration malignant transformation malignant neoplasm  cancer growth and invasion  metastasis (liver)
  • Slide 25 - 13/12/2010 25 Colon cancer ASSESSMENT FINDINGS1. Change in bowel habits- Most common 2. Blood in the stool 3. Anemia 4. Anorexia and weight loss 5. Fatigue 6. Rectal lesions- tenesmus, alternating D and C
  • Slide 26 - 13/12/2010 26 Colon cancer Diagnostic procedures & findings 1. Fecal occult blood 2. Sigmoidoscopy and colonoscopy 3. BIOPSY 4. CEA- carcino-embryonic antigen
  • Slide 27 - 13/12/2010 27 Colon cancer Complications of colorectal CA 1. Obstruction 2. Hemorrhage 3. Peritonitis 4. Sepsis
  • Slide 28 - 13/12/2010 28 Colon cancer Risk factors 1. Increasing age 2. Family history 3. Previous colon CA or polyps 4. History of IBD 5. High fat, High protein, LOW fiber 6. Breast Ca and Genital Ca 7. Have an inflammatory disease If you eat a lot of animal sources If your not physically active Or Obese
  • Slide 29 - 13/12/2010 29 Stages of Colon Cancer Stage 0- In Stage 0, the cancer is at a very early stage and is located only in the inner lining of the colon. The recommended treatment for Stage 0 colon cancer is surgical removal of the tumor, along with parts of the colon on either side of the tumor site. If detected early, colon cancer is highly curable and has a low risk for recurrence.
  • Slide 30 - 13/12/2010 30 Stages of Colon Cancer (continued) Stage 1- in this stage, the cancer has grown through several layers of the colon, but is still confined to the wall of the colon. It has not spread to nearby organs as yet. Surgery is the recommended treatment at Stage I. Stage I is also highly curable, with a low risk for recurrence.
  • Slide 31 - 13/12/2010 31 Stages of Colon Cancer (continued) Stage 2- In Stage II, the cancer has spread (metastases) to nearby organs or tissues, but not to the lymph nodes. Lymph nodes are small, bean-shaped structures where cells are stored; nodes can trap cancer cells or bacteria traveling through the body. The recommended treatment for Stage II is surgical removal of the tumor. Adjuvant therapy (chemotherapy and radiation therapy) is also suggested for Stage II patients with recurrences.
  • Slide 32 - 13/12/2010 32 Stages of Colon Cancer (continued) Stage 3- In this stage, the cancer has spread outside the large intestine to regional lymph nodes, but not to other body parts. Treatment for Stage III colon cancer includes surgical removal of a section of the colon and rejoining the remaining ends (anastomosis). Surgery is usually followed by chemotherapy. Studies have shown that the number of lymph nodes involved affects the outcome. Patients with 1-3 nodes involved have significantly greater survival rates than those with 4 or more nodes involved.
  • Slide 33 - 13/12/2010 33 Stages of Colon Cancer (continued) Stage 4- Stage IV is the most advanced stage of colon cancer. The cancer has spread beyond the colon, rectum or regional lymph nodes to distant organs or tissue (such as liver, ovaries and lungs). Although cancer is not usually curable at this stage, surgery is still the recommended treatment. Surgical resection of the colon and reconnection of the large intestine is done so as to blockage of the colon and any other local complications. Chemotherapy and/or radiation are generally given for palliative purposes.
  • Slide 34 - 13/12/2010 34 Symptoms of Colon Cancer Persistent Constipation Diarrhea Blood in the Stool And Unexplained Fatigue
  • Slide 35 - 13/12/2010 35 The Difference between a Normal Colon and a Colon with Cancer
  • Slide 36 - 13/12/2010 36 The Difference between a Normal Colon and a Colon with Cancer (Continued) The Colon on the Left is a normal Colon and the Colon on the right is a Colon with Cancer. You can see the difference of the two The normal Colon has a bigger opening and the Colon with cancer has a small opening There is also a difference in color. The normal Colon is more yellowish and the Colon with cancer is more tanish. Notice that the Colon with cancer has more veins and the normal Colon has fewer
  • Slide 37 - 13/12/2010 37 Colon cancer MEDICAL MANAGEMENT 1. Chemotherapy 2. Radiation therapy
  • Slide 38 - 13/12/2010 38 Colon cancer SURGICAL MANAGEMENT Surgery is the primary treatment Based on location and tumor size Resection, anastomosis, and colostomy (temporary or permanent)
  • Slide 39 - 13/12/2010 39 Surgery Surgery or "resection" of the colon involves cutting away the portion of the colon that is diseased, and reconnecting the two healthy parts (anastomosis). In a small percentage of patients with colon cancer (about 15 percent) the surgeon will be unable to reconnect the healthy parts. In such a case, a temporary or permanent colostomy is used. A colostomy is a surgical opening (stoma) through the wall of the abdomen into the colon, which provides a new path for waste material to leave the body. A special bag is worn to collect the body's waste.
  • Slide 40 - 13/12/2010 40 Colon Cancer Preventions Colon cancer can be prevented and cured through early detection Changing your eating habits( more fiber and less fats) Don’t smoke and drink less
  • Slide 41 - 13/12/2010 41 Future Research You may have heard that taking aspirin prevents colon cancer. This is an exciting area of research, and studies are currently underway to evaluate whether aspirin can prevent the recurrence of precancerous colon polyps.
  • Slide 42 - 13/12/2010 42 Colon Cancer Deaths (Continued) Approximately 6% of Americans will develop colon cancer and 40% of those will die of the disease There are about 134,000 new cases and 55,000 deaths occur annually 90% of deaths are over people 45 years old
  • Slide 43 - 13/12/2010 43 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
  • Slide 44 - 13/12/2010 44 Colon cancer NURSING INTERVENTION 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
  • Slide 45 - 13/12/2010 45 Colon cancer NURSING INTERVENTION Post-Operative care 1. Monitor for complications Leakage from the site, prolapse of stoma, skin irritation and pulmo complication 2. Assess the abdomen for return of peristalsis
  • Slide 46 - 13/12/2010 46 Colon cancer NURSING INTERVENTION Post-Operative care 3. Assess wound dressing for bleeding 4. Assist patient in ambulation after 24H 5.provide nutritional teaching Limit foods that cause gas-formation and odor (Cabbage, beans, eggs, fish, peanuts) Low-fiber diet in the early stage of recovery
  • Slide 47 - 13/12/2010 47 Colon cancer NURSING INTERVENTION 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
  • Slide 48 - 13/12/2010 48
  • Slide 49 - 13/12/2010 49 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
  • Slide 50 - 13/12/2010 50 Colon cancer NURSING INTERVENTION: COLOSTOMY CARE BEST time to do skin care is after shower Apply tape to the sides of the pouch before shower Assume a sitting or standing position in changing the pouch
  • Slide 51 - 13/12/2010 51 Colon cancer NURSING INTERVENTION: COLOSTOMY CARE Instruct to GENTLY push the skin down and the pouch pulling UP Wash the peri-stomal area with soap and water Cover the stoma while washing the peri-stomal area
  • Slide 52 - 13/12/2010 52 Colon cancer NURSING INTERVENTION: COLOSTOMY CARE Lightly pat dry the area and NEVER rub Lightly dust the peri-stomal area with nystatin powder
  • Slide 53 - 13/12/2010 53 Colon cancer NURSING INTERVENTION: COLOSTOMY CARE 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
