Intro to Oncology- G Flashcards
1) Cancer of the skin or in tissues that line or cover the internal organs.
2) Cancer in bone, cartilage, fat, muscle, blood vessels or other connective or supportive tissue
3) Cancer in blood cells r bone marrow
4) Cancer in immune system
1) Carcinoma
2) Sarcoma
3) Leukemia
4) Lymphona/myeloma
Factors to consider in Carcinogenesis
- Heredity- Genes
- Immunity-HIV
- Chemical- Asbestos
- Physical- UV radiation
- Viral
- Bacterial- H. pylori
- Lifestyle- Age, occupation, ethnicity, deprivation
MALT Lymphoma caused by what?
H. pylori
Single biggest cause of cancer
Smoking
3 types of clinical manisfestations
1) Subclinical
2) Local- Ex: Pain,fractures= Multiple myeloma
3) Systemic- Ex: Fever, night sweats, weight loss
What are some microscopic appearances of Cancer Cells (7)
1) Large number of irregularly shaped dividing cells
2) Large, variably shaped nuclei
3) Small cytoplasmic volume relative to nuclei
4) Variation in cell size and shape
5) Loss of normal specialized cell features
6) Disorganized arrangement
7) Poorly defined tumor boundry
For most solid tumors, the TNM system is used. What is this?
T=Tumor size (primary tumor) {0-4}
N=Nodal involvement {0-4}
M= Metastatic spred {0-1}
Stages I-IV
I= Single Location II= 2 or more locations, same side of diaphragm III= 2 or more locations both sides of diaphragm IV= Disseminated
Karnofsky (100-0%) and the ECOG (0-4) does what?
Performance status- consistent predictor of treatment tolerance and outcome.
What are treatment goals in cancer and the 3 basic modalities?
- Cure, Prolong survival, Improve quality of life.
- Surgery, Chemotherapy, Radiation

2) Secondary prevention is avoiding cancer from __________ in a previously treated patient.
1) Occuring
2) Recurring
What type of light is most common kind of sunlight at earths surface and reaches beyond top layer of skin. Causes cells to age and can damage DNA. Linked to long-term skin damage (wrinkles), but also skin cancers.
UVA
What light is mostly absorbed by ozone and does not penetrate skin deeply. Can cause direct damage to to DNA. Linked to sunburns and primary cause of skin cancers
UVB
What light is most dangerous but does not reach the ground?
UVC
