Toxicity

-Most often in the region being irradiated and may be increased if concomitant chemotherapy is given. Acute toxicity most often begins within 2 weeks of the initiation of treatment occur when normal cells within the treatment area are damaged and cellular death exceeds regeneration. -Body tissues most affected are those that normally proliferate rapidly, such as the skin, epithelial lining of the GI tract, and bone marrow. -Alopecia, radiation dermatitis, stomatitis (inflammation of the oral tissues), decreased salivation and xerostomia (dryness of the mouth), mucositis (inflammation of the lining of the mouth, throat, and GI tract), anorexia, N, V, D, leukopenia, thrombocytopenia, fatigue, malaise. -Late effects (approximately 6 months to years after treatment) may occur in body tissues that were in the field of radiation. These effects are chronic, usually due to permanent damage to tissues, and loss of elasticity. Severe late effects include fibrosis, atrophy, ulceration, and necrosis, and may affect the lungs, heart, CNS, and bladder.

Hyperthermia

-The use of hyperthermia, which is the generation of temperatures greater than physiologic fever range (greater than 106.7F), has been used for many years to destroy cancerous tumor -Most effective when combined with radiation, chemo, or biologic therapy. It is thought to alter cellular membrane permeability when used with chemotherapy, allowing for an increased uptake of the chemotherapeutic agent. -Heat can be produced by using radio waves, ultrasound, microwaves, magnetic waves, hot-water baths, or even hot-wax immersions.

Excisional Biopsy

-Used for small, easily accessible tumors of the skin, upper and lower GI tract, and Upper respiratory tract -removal of tissue surrounding the tumor decreases chance of remaining microscopic malignant cells causing the recurrence of cancer -decreases chance of seeding tumor cells in surrounding tissue -provides entire tissue specimen for the pathologist to stage and grade tumor

Gene therapy

-includes approaches that correct genetic defects, manipulate genes to induce tumor cell destruction, or assist the body's immune defences -Tumor directed therapy - introduction of a therapeutic gene (suicide gene) into tumor cells in an attempt to destroy them. It is difficult to identify the gene that will cause the most damage and those with wide spread disease would need multiple injections to treat EVERY SITE of the disease -Active immunotherapy - administration of genes that will invoke the anti-tumor responses of the immune system -Adoptive immunotherapy is the administration of genetically altered lymphocytes that are programmed to cause tumor destruction
