This presentation provides general information about cancer treatment options. Consult with your health care professional if you have any questions or for additional information because each case is unique.

Where Health Care Professionals Go for Information

Conventional Treatment Options

•Surgery•Chemotherapy•Radiation therapy

Surgery

•Sometimes used to diagnose, treat, or prevent (prophylactic) cancer

•Extent of surgery and potential for anesthesia depends on condition

•Preoperative testing sometimes needed to determine appropriateness and ability to recover from surgery

Surgery (cont’d)

“The best chance of a cure from many types of cancer is to remove all of the cancer as soon as possible after diagnosis. If you have a solid tumor, sometimes surgery alone will cure the cancer, but you may need chemotherapy, radiation therapy, or other treatment, too. Your health care team will discuss your best treatment options with you.”

Surgery (cont’d)

•Minor surgeries and biopsies have lower risk than major surgery/incisions

•Risks are generally low, but may include: – During surgery: Bleeding, damage to internal

organs, and reactions to anesthesia or drugs used

– After surgery: Pain, infection, bleeding, and slow recovery of other body function (ie, bowels)

Chemotherapy

•Use of medicines or drugs to treat cancer/disease

•Unlike radiation or surgery that targets a particular area, chemotherapy works throughout the body and can kill cancer cells that have spread to other parts of the body, far from the original tumor

Chemotherapy (cont’d)

•Goals of chemotherapy: Cure, slow growth, kill any spreading cancer cells, and relieve cancer symptoms

•May receive chemotherapy orally, via the skin, or injected into the body

Chemotherapy (cont’d)

•Potential side effects:– Anemia– Fatigue– Hair loss– Increased risk of bleeding, bruising, and

infection– Nausea and vomiting– Appetite changes and/or weight change

Chemotherapy (cont’d)

•Potential side effects (cont’d):– Constipation and/or diarrhea– Mouth, gum, and throat problems– Nerve or muscle problems– Skin and nail changes– Bladder, kidney, or urine problems

Radiation Therapy

•Local exposure of the body to high energy particles or waves (X-ray, gamma rays, electron beams, etc) to destroy or damage cancer cells

•Often performed multiple times for the same cancer

Radiation Therapy (cont’d)

•Many types of radiation therapy treatments are available—selection depends upon the cancer and severity

•Sometimes given orally or intravenously (IV), but still usually has only local effects

•Given alone or in conjunction with other treatment

Radiation Therapy (cont’d)

•Potential side effects:– Fatigue– Skin problems– Hair loss– Blood count changes– Eating problems– Damage to healthy cells– Small, but increased risk of another

cancer

Taking Care of Yourself During Radiation

•Get rest•Eat a balanced and nutritious diet•Take care of your skin at the treated area

•Tell your doctor about all medications before treatment

Progressive Treatment Options

•Targeted therapy•Immunotherapy•Hyperthermia•Lasers•Photodynamic therapy•Bone marrow and stem cell transplants

•Molecular targeted therapy

Targeted Therapy

•Drugs that specifically target cancer cells by identifying cancer-specific gene changes

•Can typically attack cancer cells with little damage to normal cells, resulting in different and usually less severe side effects than traditional chemotherapy

Targeted Therapy (cont’d)

•Used for many types of cancer to cure, slow growth, kill metastases, or relieve symptoms

•Types of targeted therapy:– Enzyme inhibitors– Apoptosis-inducing drugs– Angiogenesis inhibitors

Targeted Therapy (cont’d)

•Side effects and severity vary based on the person and type of cancer treated

•Potential side effects:– Skin problems (ie, rash, dry skin, and

itching)– Changes in hair growth or color– Changes around the eyes– High blood pressure– Bleeding and clotting issues

Targeted Therapy (cont’d)

•Potential side effects (cont’d):– Nausea and vomiting– Constipation– Mouth sores– Shortness of breath– Cough– Fatigue– Headache– Hand and foot swelling

Immunotherapy

•Uses your own immune system to fight cancer by stimulating your own immune system (active) or supplementing with immune system components (passive)

•May treat some cancers on its own, but typically used in conjunction with other treatments

Immunotherapy (cont’d)

•Examples include monoclonal antibodies, vaccines, and immunomodulating agents

•Certain immunotherapy agents are approved to treat certain cancers

•Side effects depend on type of immunotherapy performed

Immunotherapy (cont’d)

•Side effects may include:– Fever– Chills– Weakness– Headache– Nausea and vomiting– Diarrhea– Low blood pressure

Immunotherapy (cont’d)

•Side effects may include (cont’d):– Rashes– Bleeding– Fatigue– Joint pain– Thinning hair

Hyperthermia

•Currently experimental and not widely used (under clinical trials)

•May use high temperatures in localized areas to destroy small tumors

•Raises regional or total body temperature to promote better effects of chemotherapy or radiation therapy

Hyperthermia (cont’d)

•Careful control of temperature, time, and location is important, but not always easy to do

Hyperthermia (cont’d)

•Local side effects may include:– Pain– Infection– Bleeding– Blood clots– Swelling– Burns and blistering – Local tissue damage

Hyperthermia (cont’d)

•Regional/whole body side effects may include:– Nausea and vomiting– Diarrhea– Potential, but rare, problems with the

heart, blood vessels, and other major organs

Lasers

•For very careful surgical work, such as cutting through body tissue or repairing the retina

•Different types include CO2, argon, and neodymium

•Shrinks or destroys a tumor with heat•May activate a drug as part of photodynamic therapy

•Pros:– More precise than scalpels– The heat can help sterilize during cutting

and reduce infection risk– Less bleeding, swelling, pain, or scarring– May shorten operating time, even

outpatient– Often less invasive– Healing time typically shorter

Lasers (cont’d)

Lasers (cont’d)

•Drawbacks:– Few doctors are trained to use lasers– Lasers are expensive and large

compared to other surgical instruments– Strict surgical safety precautions

required– May require multiple treatments to fully

eliminate a cancer

Photodynamic Therapy

•Uses specialized photosensitizing agent drugs, typically injected into the bloodstream, and light to kill cancer cells

•Drug is absorbed over time by the cancer cells and light is applied to:– Create a chemical that kills the cells– Destroy cancer-feeding blood vessels– Alert the immune system to attack cancer

cells

Photodynamic Therapy (cont’d)

•As effective as surgery and radiation in certain cancers, but can only impact areas reached by light (skin and linings of organs)

•Drugs on market: – Porfimer sodium– Aminolevulinic acid (ALA)– Methyl ester of ALA

Photodynamic Therapy (cont’d)

•Pros: – No long-term side effects when used

properly– Less invasive than surgery– Usually quick, outpatient treatment– Can have precise targeting– Can repeat at the same site– Little or no permanent scarring– Costs less than many other treatments

Photodynamic Therapy (cont’d)

•Drawbacks:– Not always appropriate for deeper or

significantly spread cancers– Not used for those with certain blood

diseases or who are allergic to porphyrins– Skin and eyes may stay sensitive to light

for some time, from 30 days–3 months– Swelling in the treated area

Photodynamic Therapy (cont’d)

•Side effects depend on the drug and treatment site, but may include:– Nausea and vomiting– Fever– Dehydration– Headache– Hiccups

Photodynamic Therapy (cont’d)

•Side effects depend on the drug and treatment site, but may include (cont’d):– Shortness of breath– Coughing up blood– Pneumonia– Bronchitis

Bone Marrow and Stem Cell Transplants

•Can help with certain leukemia, myeloma, and lymphoma treatments

•May use to replace bone marrow destroyed by disease, including blood-related cancers, chemotherapy, or radiation

•Stem cells are grafted into the patient after a high dose of radiation/chemotherapy

•May come from patient or matched donor

Bone Marrow and Stem Cell Transplants (cont’d)

•Tests are required to determine appropriateness for procedure

•Patients who do best are usually:– Younger– In early stage of disease– Have not already had many treatments

Bone Marrow and Stem Cell Transplants (cont’d)

•Insurance may not cover or cover well

•In-patient hospital stay necessary•Significant demand placed on the body, possibly including central venous line placement

Bone Marrow and Stem Cell Transplants (cont’d)

•Possible short-term side effects:– Fever and chills– Shortness of breath– Hives– Chest tightness– Low blood pressure

Bone Marrow and Stem Cell Transplants (cont’d)

•Possible short-term side effects (cont’d):– Coughing– Chest pain– Low urine output– Weakness

Bone Marrow and Stem Cell Transplants (cont’d)

•Possible long-term side effects, including 1 year later:– Graft-versus-host disease– Infections– Lung, kidney, liver, and heart problems– Low thyroid levels– Fatigue– Memory loss– Depression

Bone Marrow and Stem Cell Transplants (cont’d)

•Possible long-term side effects, including 1 year later (cont’d):– Cataracts– Slowed growth (children)– Reproductive problems– Secondary cancers– Changes in social relationships and feelings

Molecular Targeted Therapy

•High specificity medications designed to inhibit proteins, genes, and pathways unique to cancerous cells

•Can help fight or delay progression of the disease

•Still new to the market and clinical trials

•Availability depends on type of cancer

Molecular Targeted Therapy (cont’d)
