| A | B |
|---|
| common cancer tests | nuclear imag, MRI, PET, Ultrasound |
| cytology | study of cells |
| excisional | remove entire tumor |
| goals of cancer therapy | cure, control, palliative, prophylaxis |
| staging - TNM | tumor size, node lymph, metastasis |
| cancer treatment | surgery, radiation, chemo, biotherapy, BMT |
| debulking | remove as much as possible |
| surgery is the _____ ___ treatment | most common |
| nonresectable | just cant get it |
| 2 types of radiation | external, internal |
| external radiation is ___ radioactive | not |
| internal radiation can be | a source of radio active |
| external radiation treatment | outpatient, reference points, shielding blocks to cover good tissue |
| internal radiation | w/in body, can be sealed or unsealed |
| sealed sources | needles, seeds, wires, catheters |
| unsealed sources | suspension or solution - iodine 131 |
| side effects of radiation | hair loss, red skin, dryness mouth, fatigue |
| degree of exposure (3) | distance, time, shielding |
| chemo drugs are called | antineoplactics |
| chemo interferes with | cell production |
| unsealed source is | systemic |
| classification of drugs | alkylating, antimetabolities, antibiotice, vince, hormones |
| extravasation | leakage of chemo into surrounding tissue |
| vesicant | harmful to good tissue |
| adverse effects of chemo | N V, stomatitis, alopecia, myelosuppression |
| biotherapy BRM's are agents | that stimulate body's natural immune system |
| 2 types of biotherapy | interferons, interluken-2 |
| nursing management for cancer | pain, fatigue, infection, bleeding, hair loss, mental status |
| lung cancer symptoms | cough, chest pain, bloody or brown colored sputum |
| diagnosis of lung cancer | sputum analysis, biopsy, xray |
| insidious | slow growing |
| tumor markers | specific proteins, antigens, hormones that cancer cells release |
| stereotatic is aka | gamma knife |
| brachytherapy | short distanct therapy |
| radioactive precautions | no kids, no pregnant, 5 minutes, 6 ft distance |
| I is | malignant cells confirmed |
| II is | spread is limited to local |
| III | tumor large |
| IV | metastazie to other parts of body |
| stem cells | cells that can generate and differentiate various tissue types |
| VOD - venous occlusive disease | injury to vessels of liver - 100 days - liver failure |
| cancer | disease resulting in uncontrolled growth of cells |
| neoplasm | new growth of abnormal cells |
| cancer cells | no regulatory mechanims - out of control |
| neoplasia | uncontrolled growth of abnormal cells |
| benign | encapsulated neoplasm - remains localized |
| malignant | non-encapsulated neoplasm that invades surrounding tissue |
| metastasis | process of spreading |
| In Situ | remain at original site |
| primary site | where cells 1st form |
| secondary site | where they spread |
| 4 ways metastasis spreads | vascular, lymphatic, implantation, seeding |
| main classes of tumors | lymphomas leukemias sarcomas carcinomas |
| sarcomas cancers are in | CT |
| carcinomas are in | epithelial cells |
| synergy | working together to produce a greater sum |
