Cancer Screening Flashcards
Number 1 Cancer in Males
Prostate
Number 1 Cancer in Females
Breast
Number 1 Cancer that Males & Females Die from Each Year
Lung & bronchus
General Cancer Prevention
Avoid tobacco Be physically active Maintain a healthy weight Limit alcohol Avoid excess sun Eat a diet rich in fruits, veggies, & whole grains & low in sat/trans fats Protect against STIs Regular screening for breast, cervical, & colorectal cancer
Principles of Screening
Disease has high prevalence
Disease has serious consequences
Detectable pre-clinical phase
Treatment for pre-symptomatic disease more effective than after symptoms develop
Positive impact on clinical health outcomes
Other Considerations for General Screening
What are patient’s co-morbid conditions?
Associated life expectancy, feasibility of treatment, effects of treatment on QOL?
What will you do with the results?
Which cancers are largely asymptomatic in the early stages?
Colorectal
Breast
Cervical
What is the leading cause of death from gynecologic malignancy in the U.S.?
Ovarian cancer
Pelvic Examination in Ovarian Cancer
No evidence they reduce mortality
Early stage tumors rarely found
Usually detected at an advanced stage & associated with a poor prognosis
Screening for Ovarian Cancer
CA 125 & TVUS
Family ovarian cancer syndrome or BRCA genes: CA 125 & TVUS
Initiation at 35 years or 5-10 years earlier than earliest age of first diagnosis
BRCA1 Carriers & Breast, Ovarian, & Contralateral Breast Cancer Risk
Breast risk: 60%
Ovarian risk: 59%
Contralateral breast risk: 83%
BRCA2 Carriers & Breast, Ovarian, & Contralateral Breast Cancer Risk
Breast risk: 55%
Ovarian risk: 16.5%
Contralateral breast risk: 62%
When to Test for BRCA for Non-Ashkenazi Jewish Women
2 1st-degree relatives with breast cancer, one
When to Test for BRCA for Women of Ashkenazi Jewish Descent
1st degree relative with breast or ovarian CA
Positive Impact on Clinical Health Outcomes for Ovarian Cancer
Annual pelvic, CA-125, and TVUS DO NOT decrease mortality from ovarian cancer
Prevention of Ovarian Cancer
Oral contraceptives
Gynecologic surgery: tubal, hysterectomy
Pregnancy
Breastfeeding
Cervical Cancer Prevention
Pap test
Death rate decreased 50% since pap administration
Cervical Cancer Screening Recommendations
Women should begin screening at age 21 unless HIV or immunocompromised
21-29 cytology every 3 years
30 years old: cytology every 3 years, co-testing cytology & HPV testing every 5
May stop after 65 if adequate screening in past 10 years with 2 negative screens
High Risk Groups for Cervical Cancer
Patients with HIV infection
Patients who are immunosuppressed
Those who had in utero DES exposure
Women who have been treated for CIN2, CIN3, or cervical cancer
Cervical Cancer: Hysterectomy Patients who Still Need Pap Smears
Surgery was done as treatment for cervical CA or pre-cancer
Hysterectomy without removal of the cervix
Cervical Cancer Prevention
Gardasil
Avoid exposure to HPV
Don’t smoke
Pap smear
Epidemiology of Breast Cancer
Most common in U.S
Second leading cause of cancer death in women
Diagnosed as a result of abnormal screening study
Primary Risk Factors for Breast Cancer
Predominantly in females
Age: 85% age 50+
Screening Tools for Breast Cancer
Mammography
Ultrasound
MRI: high risk patients
