MEDICAL SURGICAL: Sir Vince ONCOLOGY muffin | BSN 2A | CEBU NORMAL UNIVERSITY Oncology f. Anaplasia - refers to disorganized, irregular cells that have nor structure and have loss of differentiation; the Onkos- meaning bulk, mass, tumor, result is always malignant (undifferentiated cell) suffix - logy - meaning “study of” Branch of medicine that deals with tumors(cancer) The diagnosis of any cancer in a person Epidemiology of Cancer Therapy (e.g. surgery, chemotherapy, radiotherapy, and Cancer affects every age group though most cancer and other modalities) cancer deaths occur in people older than 65 years of age Follow-up of cancer patients after successful treatment Age of 60 - as verbalized Palliative care of patients with terminal malignancies Cancer ranks 3rd as the cause of morbidity in the Ethical questions surrounding cancer care Philippines Screening efforts of populations, or of the relatives of Highest incidence of all cancer is prostate cancer patients (in types of cancer that are thought to have a Highest cancer incidence in males in order of frequency: hereditary basis, such as breast cancer) prostate cancer, lung cancer and colorectal cancer Highest cancer incidence in females in order of Normal Cell frequency: breast cancer, lung cancer and colorectal cancer Characteristics of Normal Cells - The Biology of Normal Cells Have limited cell division Malignant Cell Undergo Apoptosis Show specific morphology Characteristics of Malignant Cell Perform specific differentiated functions Rapid cell division and growth: Adhere tightly together regulation of the rate of mitosis is lost Non migratory No contact inhibition: Grow in orderly and well regulated manner cells do not respect boundaries of other cells and invade Are euploid their tissue areas Loss of differentiation: Normal cell growth (cell cycle) consists of 5 intervals or cells lose specialized characteristics of function for that cell phases type and revert back to an earlier, more primitive cell type Differentiation - refers to the process whereby cells Ability to migrate (metastasize); develop specific structures and functions in order to cells move to distant areas of the body and establish new specialize in certain tasks site malignant lesions (tumors) Apoptosis - cell suicide, normal event. Alteration in cell structure: differences are evident between normal and malignant cells with respect to cell membrane, cytoplasm and overall cell shape Self-survival: a. may develop ectopic sites to produce hormones needed for own growth b. can develop a connective tissue stroma to support growth c. May develop own blood supply by secreting angiotensin growth factor to stimulate local blood vessels to grow into tumor Cellular Adaptation a. Hypertrophy - increase in size of normal cells b. Atrophy - shrinkage of cell size c. Hyperplasia - increase in the number of normal cells d. Metaplasia - conversion from the normal pattern of differentiation of one type of cell into another type of cell not normal for that tissue. Replacement of other mature cell. e. Dysplasia - refers to an alteration in the shape, size, appearance and distribution of cells (reversible) 1 ㅤㅤㅤㅤ - Chapter Title ㅤㅤㅤㅤ - Main Lesson/Topic ㅤㅤㅤㅤ - Sub Lesson/Topic ㅤㅤㅤㅤ - Keywords ㅤㅤㅤㅤ - Functions ㅤㅤㅤㅤ - Synonyms Initiation Normal Malignant occurs when carcinogen damages DNA Speed of growth slow growing fast growing carcinogenesis cause changes in the structure and function of the cell at the genetic or molecular level.

Assessment of the patient's subjective experiences and an objective assessment of the oropharyngeal tissues and tooth are important for the treatment of oral mucositis. Radiation-associated skin impairment. maintaining skin integrity. cleansing the skin, promoting comfort, reducing pain, preventing additional trauma, and preventing and managing infection. Alopecia. Provide information about hair loss and support the patient and family in coping with changes in body image. Malignant skin lesions. cleansing the skin, reducing superficial bacteria, controlling bleeding, and reducing odor. protecting the skin from further trauma, and relieving pain. Promoting Nutrition Anorexia. Anorexia may occur because people feel full after eating only a small amount of food Malabsorption. Surgical intervention may change peristaltic patterns, later gastrointestinal secretions, and reduce the absorptive surfaces of the gastrointestinal mucosa, all leading to malabsorption. Cachexia. Assess patients who are at risk of altered nutritional intake so that appropriate measures may be instituted prior to nutritional decline. Relieving Pain Assessment. Assess the patient for the source and site of pain as well as those factors that increase the patient's perception of pain. Cancer pain algorithm.

Provide education and support to correct fears and misconceptions about opioid use. Decreasing Fatigue Assessment. Assess physiological and psychological stressors that can contribute to fatigue and use several assessment tools such as a simple visual analog scale to assess levels of fatigue. Exercise Pharmacologic interventions. Occasionally pharmacologic interventions are utilized. including antidepressants for patients with depression, anxiolytics for those with anxiety, hypnotics for patients with sleep disturbances, and psychostimulants for some patients with advanced cancer or fatigue that does not respond to any medication. Improving Body Image and Self-esteem Assessment. Identify potential threats to the patient's body image experience, Assess the patient's ability to cope with the many assaults to the body image experienced throughout the course of the disease and treatment. Sexuality, Identify physiologic, psychologic or communication difficulties related to sexuality or sexual function. Assisting in the Grieving Process Assessment. The nurse assesses the patient's psychological and mental status, as well as the mood and emotional reaction to the results of diagnostic testing and prognosis. Grieving is a normal response to these fears and to actual or potential losses. Monitoring and Managing Potential Complications Infection. The nurse monitors laboratory studies to detect any early changes in WBC counts. Septic shock. Neurologic assessments are carried out, fluid and electrolyte status is monitored, arterial blood gas values and pulse oximetry are monitored, and IV fluids, blood, and vasopressors are administered by the nurse. Bleeding and hemorrhage. Promoting Home and Community-Based Care Teaching patients self-care. Follow-up visits and telephone calls from the nurse assist in identifying problems and are often reassuring, increasing the patient's and the family's comfort in dealing with complex and new aspects of care. Continuing care. The responsibilities of the home care include assessing the home environment, suggesting modifications at home or in care to help the patient and the family address the patient's physical needs 12 ㅤㅤㅤㅤ - Chapter Title ㅤㅤㅤㅤ - Main Lesson/Topic ㅤㅤㅤㅤ - Sub Lesson/Topic ㅤㅤㅤㅤ - Keywords ㅤㅤㅤㅤ - Functions ㅤㅤㅤㅤ - Synonyms
