Oncology Nursing Michael Norbert L. De Guzman, RN, MAN Oncology defined Branch of medicine that deals with the study, detection, treatment and management of cancer and neoplasia “Root words” Neo- new Plasia- growth Plasm- substance Trophy- size +Oma- tumor Statis- location “Root words” A- none Ana- lack Hyper- excessive Meta- change Dys- bad, deranged Characteristics of Neoplasia Uncontrolled growth of Abnormal cells 1. Benign 2. Malignant 3. Borderline Characteristics of Neoplasia BENIGN Well-differentiated Slow growth Encapsulated Non-invasive Does NOT metastasize Characteristics of Neoplasia MALIGNANT Undifferentiated Erratic and Uncontrolled Growth Expansive and Invasive Secretes abnormal proteins METASTASIZES PROLIFERATIVE PATTERNS Anaplasia: cells that lack normal cellular characteristics and differ in shape and organization Dysplasia: bizarre cell growth, differ in size, shape, or arrangement from other cells of the same type of tissue PROLIFERATIVE PATTERNS Metaplasia: conversion of one type of mature cell into another type of cell Nomenclature of Neoplasia Tumor is named according to: 1. Parenchyma, Organ or Cell Hepatoma- liver Osteoma- bone Myoma- muscle Nomenclature of Neoplasia Tumor is named according to: 2. Pattern and Structure, either GROSS or MICROSCOPIC Fluid-filled🡪 CYST Glandular🡪 ADENO Finger-like🡪 PAPILLO Stalk🡪 POLYP Nomenclature of Neoplasia Tumor is named according to: 3. Embryonic origin Ectoderm ( usually gives rise to epithelium) Endoderm (usually gives rise to glands) Mesoderm (usually gives rise to Connective tissues) BENIGN TUMORS Suffix- “OMA” is used Adipose tissue- LipOMA Bone- osteOMA Muscle- myOMA Blood vessels- angiOMA Fibrous tissue- fibrOMA MALIGNANT TUMOR Named according to embryonic cell origin 1. Ectodermal, Endodermal, Glandular, Epithelial Use the suffix- “CARCINOMA” Pancreatic AdenoCarcinoma Squamos cell Carcinoma MALIGNANT TUMOR Named according to embryonic cell origin 2. Mesodermal, connective tissue origin Use the suffix “SARCOMA FibroSarcoma Myosarcoma AngioSarcoma “PASAWAY” 1. “OMA” but Malignant HepatOMA, lymphOMA, gliOMA, melanOMA 2.
