Oncology Rehabilitation: Web-based Learning for Physical Therapists Who Provide Rehabilitation to Patients with Breast Cancer File #3 The Cancer Team Physical Therapy The Cancer Team : Physical Therapy • Realize the expertise and importance of physical • therapy necessary to treat the breast cancer patient. Physical Therapy should be prominent in establishing and following a plan of treatment for the breast cancer patient. 2 MEDICAL TEAM General Surgeon Plastic Surgeon Psychiatrist/psychologist Rehabilitation Director Physical Therapist Nurse Social Worker Registered Dietician Occupational Therapist Vocational Counselor Respiratory therapist 3 PHYSICIANS’ ROLE IN THE TREATMENT OF BREAST CANCER 4 • GP or Internist - diagnoses and refers to specialists as needed. • Oncologist – coordinates diagnostic and treatment interventions. • Radiologist - determines required methods and dosage of radiation • Pathologist - diagnoses & classifies disease • Surgeon - determines procedure and attempts to save surrounding structures. • Plastic Surgeon – restores appearance leading to a positive self image. Who prescribes rehabilitation? 5 Staging to Treatment • Breast cancer treatment programs are dependent upon the diagnosis rendered by the pathologist and the collaborative treatment plan established by the physician and the patient. All diagnostic studies presented will make a realistic breast cancer rehabilitation program possible. 6 7 (Slide permitted by the American Cancer Society) Medical Interventions: • Chemotherapy • Radiation • Surgery • Hormone Therapy • Immunotherapy • Bone Marrow Transplants • Prescribed Physical Rehabilitation 8 Chemotherapy 9 Chemotherapy • The use of drugs to treat cancer. • Combination Chemo - Some drugs work better with another drug. • Why chemotherapy? – Regional and systemic disease – Designed to kill cancer cells and stop them from growing – Goals: cure; control; palliative; prophylactic (Otto, 2004) 10 Medical interventions can be mixed in an attempt to reach maximal progress with chemotherapy drugs or other treatment regimes. Combination Chemotherapy: Some drugs work better With another drug, Than when used alone 11 Chemotherapy • Schedule therapy around chemotherapy – Medications being used – Treatment schedule 12 Chemotherapy Agents • ALKYLATING: Damage DNA in nucleus which has decreased ability to repair. – Examples: nitrogen mustard & cyclophosphosphamide • ANTIMETABOLITES: Replace compounds needed for DNA synthesis. – Examples: 5-fluorouracil & methotrexate . (Abraham, 2005) 13 Agents • INHIBITORS OF CELL: Inhibit cell mytosis, so dividing cells cannot separate chromosomes into daughter cells. – Examples: vincristine, vinblastine & colchicine • ANTI-TUMOR ANTIBIOTICS: Bind DNA and block RNA preventing protein growth. – Examples: doxorubicin, bleomycin, mitomycin & cisplatin (Abraham, 2005) 14 During chemotherapy notify M.D. if: • • • • • • • • • 100 A fever greater than ______ degrees. Bleeding ___________ or unexpected bruising. rash swelling A ________ or allergic reaction (_______) Chills soreness Pain / _______ at chemo injection site. Unusual pain SOB vomiting Diarrhea or prolonged ___________. Blood ___________ in urine. (Otto, 2004) 15 Side Effects: Chemotherapy • • • • • • • • • • Nausea Vomiting Loss of Appetite Menstrual Irregularities Low Blood Count Hair Loss Mouth Sores Conjunctivitis Ulcers Fatigue • • • • • • • • Heart Problems Headache Pain at IV Site Numbness Dizziness Bladder Liver Problem Infertility Depression (Adcock, 1992) 16 Specific examples of chemotherapy side effects • Cytoxan (Oral/IV) Nausea, vomiting, loss of appetite, menstrual irregularity, low blood counts, hair loss. Possible urinary bladder problems, liver problems, infertility • Adriamycin(IV) Hair loss, mouth sores, nausea, vomiting, low blood counts. Possible heart problems, nail and skin darkening, liver problems. • Viscristine(IV) Hair loss, tingling and numbness in fingers and toes, pain at IV site, constipation, headache. Possible muscle and jaw pain, loss of reflexes, depression, insomnia • 5 fluorouracil (5FU) Mouth sores, nausea, vomiting, diarrhea, low blood counts, loss of appetite, hair loss, sore throat. Possible rash, nail change, skin darkening (Otto, 2004) 17 Hormone Therapy 18 Hormone Therapy • Natural or Synthetic change of hormones to treat disease. • Three Methods of treatment 1. Medication (injected or oral) 2. Surgical removal of hormone producing gland. 3. Radiation to destroy hormone producing cells. (Otto, 2004) 19 HORMONE THERAPY • Treatment plan: • Tamoxifen - Blocks body’s use of estrogen. • Hormones used: Adenocorticoids (Prednisone & Cortisone), Estrogen & Progesterone (Female hormones), Androgen (Male hormone) . (Otto, 2004) 20 Side Effects: Hormone Replacement Therapy • Tamoxifen - Hot flashes, nausea, vaginal • • discharge or itching. Possible headache, bone pain, depression. Progestins - Weight gain, edema, breast tenderness. Possible carpal tunnel syndrome, hair loss. Prednisone - Mood changes, increased appetite, fluid retention. Possible acne, muscle weakness, diabetes, high blood pressure. (Otto, 2004) 21 Radiation 22 RADIATION ENERGY CARRIED BY WAVES OR A STREAM OF PARTICLES. DELIVERED BY MACHINE OR FROM RADIOACTIVE SUBSTANCES. 23 External Beam Radiation • A machine (Linear accelerator) that directs high energy rays or particles to the Cancer and margins of normal tissue. Damaging DNA (directly or indirectly) • Best used for: ______________________ __________________________________ Mapping (Taking about an hour) • Preparation: _______________________ Every weekday for five to six weeks + a boost (+ five) • Amount: __________________________ Standard type of radiation Average dose post lumpectomy 4,500 to 5,000 centigray (cGy) Boost dose 1,000 to 1,500 cGy 24 (www.mayoclinic.com, 2004) 25 (Slide permitted by the American Cancer Society) Internal Beam Radiation • Radioactive substance is sealed in small containers, • • • such as wires and tubes then placed directly into tumor or body cavity. Container of radioactive material placed Intracavitary: ______________________ in a cavity of the body __________________________________ Radioactive source placed a short Brachytherapy: _____________________ distance from affected area __________________________________ Problem: Radiation may cause disease that is being treated. Donegan and Spratt (2002), report second breast cancers can be linked to radiotherapy for primary breast cancer for exposed women under age 45. (Otto, 2004) 26 HIGH DOSES OF RADIATION THAT DAMAGE AND DESTROY CANCER CELLS CAN ALSO EFFECT NORMAL CELLS, BUT THE SIDE EFFECTS ARE LESS THAN THE BENEFITS (Risks effects less than 1% of women treated with radiation) (Elk, 2003) 27 Radiation after mastectomy recommended if: • Tumor > 2 inches (5 centimeters) and positive lymph nodes • Cancer cells found in many lymph nodes • Tumor close to rib cage or chest wall musculature, which could lead to spreading (METS) • Inflammatory breast cancer, which is described as cancer cells blocking lymph vessels in the skin of the breast, appearing with redness and heat of the breast. (Altman, 1992) 28 Success with radiation • Depends on whether cells multiply between • • fractions*. To much time between fractions increases doubling time*. Intervals should be short to kill greatest number of Ca cells. Schedule usually 5 days/week for 5-8 weeks or more (Prevents to much RAD to skin and normal tissue). Split Course Therapy allows patient several weeks off in middle of treatment to allow body recovery time. (Dollinger et al, 2002) 29 Radiation after breast conserving surgical procedures 10 years later No radiation radiation Recurrence rate Mortality 31.9% 24.7% 10.5% 20.9% (Dixon, 2006) 30 Side Effects: Radiation • Acute – – – – – – Itching / Swelling Skin Reddening / Burn Fatigue Nausea / Vomiting / Loss of appetite Decrease in lab values including blood counts Pain in the treated regions • Long Term – Fibrosis (Firmness of the Breast) – Radiation induced 2nd Malignancy (Otto, 2004) 31 Surgery 32 Why Surgery? • Preventive: Patient known to be at high risk. • Diagnostic: Biopsy to obtain tissue. Exploratory surgery for staging. • Cure: Removal of cancerous tissue. Best when combined with other interventions. (Dollinger, 2002) 33 • Palliation: Relieve pain--restore function in terminal patients to increase quality of life. • Reconstruction: Correct function and cosmetic defects. (Dollinger, 2002) 34 Diagnostic Surgery • Sentinel lymph node biopsy • 70% of stage 1 breast cancer have negative • • • nodes. Multiple node dissection can increase complications. Sentinel node is the first draining node. If this is negative, good chance other nodes are also negative. Has become procedure of choice. (Dollinger, 2002) 35 Breast Surgery Simple mastectomy Remove breast tissue only. • ____________ • • Chest wall muscles and axillary lymph intact. Generally precancerous condition. Lumpectomy ____________ Remove tumor and margin of surrounding tissue. Axillary dissection to determine need of other interventions. Modified Radical Breast tissue removed, some ____________ axillary nodes. Spare pectoralis major pectoralis minor may be removed, getting to axilla. (Altman, 1992) 36 Breast Surgery Radical Mastecomy • ____________ Remove breast tissue, pectoralis major, pectoralis minor and all axillary nodes, not common choice. Axillary Dissection • ____________ Axilla primary site of regional metastasis needed for staging. Estimated 27 Lymph nodes in axilla.

Schuster, MD Board Certified Plastic Surgeon) 48 Tattoo of areola (Slide donated with permission to show by: Ronald H. Schuster, MD Board Certified Plastic Surgeon) 49 Post-surgical TRAM • As shown in the example, the TRAM procedure is very complicated and requires the expertise of a surgeon and plastic surgeon. • Precautions are needed to avoid any possible complications that could harm transferred tissue, leading to necrosis. Such things as aggressive exercise and stretching are potential problems. 50 Other less performed breast procedures: • Skin–sparing mastectomy: surgery removing breast tissue by making an incision around the areola. • Subcutaneous (nipple sparing) mastectomy: surgery removes only breast tissue, sparing the skin, nipple, areola, chest wall muscles and lymph nodes. (Altman, 1992) 51 Time Out Test • Why should physical therapy be a vital member of the cancer team? • A tumor larger than 1cm, usually receives removal and what other ANSWERS Expertise in Rehabilitation; chemotherapy; half-life; damaging DNA; False; Less tissue trauma ;Musculature in not attached, microsurgery needed to Restore circulation. • • • • • medical intervention? Knowing how a medication will function in the body is called? What is radiation best used for? Radiation only destroys cancer cells? T / F What is the advantage of sentinel node biopsies? A free flap surgical procedure lets you know what? 52 Side Effects: Surgery • Cosmetic and Functional • Infection • Psycho-social Issues (Patient’s may have problems dealing with their diagnosis and prognosis as well as treatment and side effects . Proper care will be needed, advise the referring physician). • Pain • Decreased function with possible deformity (Otto, 2004) 53 Bone Marrow Transplant 54 BONE MARROW TRANSPLANTS • Bone Marrow produces 3 types of cells. Red Blood Cells =Cells that transport oxygen from the lungs to other parts of the body. (Too few RBC's called Anemia) White Blood Cells = Defense mechanism that fights infection. Platelets = prevention of bleeding by the formation of clots. • BMT = Replacement of diseased or destroyed bone marrow with healthy cells (Otto, 2004) 55 Types of Transplants: • Autologous--Patient's own marrow is removed, stored, and later returned. • Syngeneic--Marrow from an identical twin. • Allogeneic--Marrow donated by another person (Often sister or brother). • Donor match completed with a blood sampling called an HLA (Human Leukocyte Antigen) (Otto, 2004) 56 When BMT might be prescribed? Solid tumors (Cancer of brain, testes, breast & lung) • • Clinical trials with high dose therapy with autologous bone marrow transplants suggest increased response rate. Studies appear inconclusive as far as the benefits of BMT for breast cancer. A randomized trial with metastatic disease showed no difference between conventional chemotherapy and autologous transplant. (Dollinger, 2002) 57 BMT Procedure • Patient selection • Allogeneic transplant: Donor matching • Autologous transplant: BM harvest • Treatment--Chemo and/or Radiation • Protective Isolation • Allogeneic/Syngeneic transplant: harvest • Marrow transplant = Reinfusion • Engraftment, a rise in blood counts • Discharge and follow-up • 4 to 6 weeks in hospital • Cost : $75,000 - $200,000 58 BMT Success • 60-80% success • 50% cure rate for AML; Late in disease 10% • 30% breast Ca. cure rate • Predictions of other Ca. cure rates not possible (www.healthline.com, 2005) 59 BMT Problem (1/2 BMT = GVHD) • Graft versus Host Disease (GVHD) 16% death rate • Symptoms: From mild skin rash to severe diarrhea to life threatening liver damage and hemorrhage. (www.healthline.com, 2005) 60 National Marrow Donor Program 100 South Robert Street St. Paul, MN. 55107 1-800-654-1247 About 1.5 million volunteers registered 61 Side Effects: Bone Marrow Transplant • Short Term – – – – – – Nausea / Vomiting Irritation of lining of mouth and GI tract Decreased Blood Counts Damage to vital organs Hair loss Loss of appetite • Long Term – – – – Infertility Early Menopause Cataracts Secondary Cancers (Otto, 2004) 62 Immunotherapy 63 Immunotherapy • Stimulates the bodies own immune system to attack the disease. • Many patients who have failed using other types of interventions made positive progress with immunotherapy. • Alter genetic make-up: 1. By removing cells that could fight Cancer 2. Inserting fighting gene into them then 3. Infusing cell back into patient. (Lange, 2005) 64 Side Effects: Immunotherapy • Interferon toxicity – Fever / Chills – Nausea / Vomiting – Anorexia – Fatigue • Monoclonal Antibody Toxicity – Fever / Chills – Dyspnea – Hypotension – Nausea / Vomiting • Interleukin 2 Toxicity – Fluid Retention / Pulmonary Edema (Otto, 2004) 65 Treatment Options Medical Interventions are determined by the risk of recurrence No Surgery Radiation Lumpectomy Chemotherapy Bone Marrow Transplant Mastectomy Hormone Therapy Immunotherapy 66 Important to follow cancer developments: • • • • • • Constant research Changes in chemotherapy medications Changes in surgical procedures Stem cell bone marrow transplants Best areas to obtain bone marrow Continual rehabilitation research 67 Deconditioning 68 All Medical interventions can lead to deconditioning of the total body. Patients should complete some exercises as tolerated during treatments 69 Complications seen with Deconditioning •Gastrointestinal •Acute/Chronic Pain •Neurological •Psychological •Hematological effects •Effects on bone (Pathological Fx) • Peripheral vascular • • • • and lymphatic Compression Cardiopulmonary Urinary signs Metabolism and Endocrine 70 American Cancer Society Clinical Trials and Research The Need for Clinical Trials Research studies to produce guidelines which reveal the effects of drugs, working alone or together, to prevent, alleviate, or cure a disease. Clinical trials lead to strategies for drugs. Examples: Tamoxifen and Raloxifene for breast cancer.
