Flashcards in August 12, 2015 - Colorectal Cancer Epidemiology and Screening Deck (10):
1

Cancer Control

1. Removal of risk factors

2. Early detection and treatment

3. Reduction of complications

2

Screening

The examination of asymptomatic people in order to classify them as likely or unlikely to have the disease.

3

Epidemiology

The study of the distribution and determinants of health-related states or events in defined populations, and the applications of this study to control health problems.

4

Risks for Colorectal Cancer

Genetic Syndromes and Family History

 

(Although, most cases of CRC occur sporadically)

5

Colorectal Cancer Incidence and Mortality

4th most common cancer

2nd leading cause of cancer death

6

Flexible Sigmoidoscopy

Can reach about 1/3 of the colon

7

Test Sensitivity

Probability that the test will be positive given that the disease is present.

8

Test Specificity

Probability that the test will be negative given that the disease is absent.

9

Relationship of Sensitivty and Specificty

By increasing sensitivity, you lower specificty.

 

Alberta sets the FIT value for 75 ng, while Quebec sets its for 250 ng. Alberta has a higher specificty, but a lower sensitivity, while Quebec has a respectively lower specificity but a higher sensitivity.
