Cancer Statistics
About 1, 529, 560 new cancer cases are expected to be diagnosed
569,490Americans are expected to die of cancer (more than 1,500 people a day)
Cancer is the second most common cause of death in the US, exceeded only by heart disease
In the US cancer accounts for nearly 1 of every 4 deaths
African Americans are more likely to develop and die from cancer than any other racial group

What is cancer?
A group of diseases characterized by uncontrolled growth of abnormal cells, when this spread or growth is uncontrolled it may lead to death.
A multistep process in which an accumulation of genetic events with a single cell line leads to a progressively dysplastic cellular appearance, deregulated cell growth and finally evident disease.

Breast Cancer Risk Assessment
Patient with moderate or high risk factors should be seen for genetics counseling
Risk reduction counseling should occur for all women with high lifetime risk
Surgical risk reduction strategies generally reserved for patients with strongly predisposing gene mutation
Risk Reduction agents Tamoxifen and Raloxifene are options after a discussion on the relative risk reduction, adverse reactions and benefits
![Page 16: DINA DUMERCY, PHARM.D., BCOP ONCOLOGY IT PHARMACIST MEMORIAL HEALTHCARE SYSTEM MIRAMAR, FLORIDA Update on Common Malignancies in Women: Breast and Cervical.](https://reader035.fdocuments.us/reader035/viewer/2022062321/56649de65503460f94adf656/html5/thumbnails/16.jpg)

HPV and Cervical Cancer
Most common sexually transmitted virus in the US
At least 50% of sexually active people will have HPV at some point in their lives
HPV Cause epithelial proliferations at cutaneous and mucosal surfaces
20 million Americans 15- 40 years of age (15% of population)are currently infected
There are more than 100 types of the virus and about 40 types of HPV are associated with genital HPV

HPV types and disease association
HPV-16 and HPV-18 are the most prevalent of the oncogenic types Associated with cervical, vulvar and vaginal cancers
HPV- 6 and HPV-11 "low-risk" types can cause genital warts and usually benign (abnormal but non-cancerous) changes in the cervix
The high efficacy of the vaccines may dramatically decrease cervical cancer, preventing up to 70% of newly diagnosed cases

Natural History of HPV Infection

Screening Recommendations
NCCN adopted the American College of Obstetricians and Gynecologists screening recommendations
Screening should begin at 21 years of age regardless of sexual intercourse status Every 2 years between 21 and 29 years of age
Adolescents who are immunocompromised (HIV, steroid use, post transplant, etc.) should also have cervical cytology screened
Both liquid based and conventional methods of cervical cytology are acceptable
![Page 47: DINA DUMERCY, PHARM.D., BCOP ONCOLOGY IT PHARMACIST MEMORIAL HEALTHCARE SYSTEM MIRAMAR, FLORIDA Update on Common Malignancies in Women: Breast and Cervical.](https://reader035.fdocuments.us/reader035/viewer/2022062321/56649de65503460f94adf656/html5/thumbnails/47.jpg)
Screening Recommendations
Combination of cytology and HPV DNA testing is appropriate for women greater than 30 years old Women who are low risk with both negative result should
be screened every 3 years HPV DNA testing is not indicated in women < 21 years old
Women 30 year and older who had 3 consecutive negative cervical cytology screening test, not immunocompromised, no history of cervical intra-epithelial neoplasia (CIN), not HIV infected, and were not exposed to DES in utero may extend the interval between cervical cytology to every 3 years

Screening Recommendation
Women who have been immunized against HPV-16 and HPV-18 should be screened by the same schedule as non-immunized
Annual gynecologic examination may still be appropriate even if cervical cytology is not tested at each visit
Women treated in the past or CIN, or cancer including status post hysterectomy should have annual screening for at least 20 years after surveillance
![Page 50: DINA DUMERCY, PHARM.D., BCOP ONCOLOGY IT PHARMACIST MEMORIAL HEALTHCARE SYSTEM MIRAMAR, FLORIDA Update on Common Malignancies in Women: Breast and Cervical.](https://reader035.fdocuments.us/reader035/viewer/2022062321/56649de65503460f94adf656/html5/thumbnails/50.jpg)
Screening Recommendation
Screening can be discontinued; In women who have had a total
hysterectomy for benign indication and have no history of high grade CIN
Women between 65 and 70 years of age and older with 3 or more negative cytology test in a row and no abnormal test in the past 10 years

HPV DNA Testing
HPV high risk DNA test- detects whether any of the 14 high risk (oncogenic) types of HPV are present, does not indicate which type is present
HPV 16/18- detects whether HPV 16 or 18 is present, used together with the HPV high-risk DNA test
Hybrid Capture 2 HPV DNA test- asses whether women are positive for any of 13 high-risk, false- positive results due to cross reactivity with non-oncogenic subtypes

HPV Vaccines
Quadrivalent HPV vaccine protect against certain types of HPV (6, 11, 16, 18)
Bivalent vaccine protects against HPV 16 and 18Vaccine most effective if started before
intercourse FDA approved for 9- 26 and 10 – 25 year old
females respectively to prevent cervical cancer and precancerous lesions due to HPV
Not clear how long immunity is present after vaccination, data suggest 5- 10 years

Diagnosis of Cervical cancer
Diagnosis often from cervical cytology, PAP smears and biopsies (Conization used to determine invasiveness)
Colposcopy, and colposcopy directed biopsies is the primary method for evaluating abnormal cervical cytology
CT scans, MRI, PET-CT and surgical staging are used to guide treatment

Cervical Cancer Treatment
Surgery for lower stage disease Observation is appropriate for lower stage (IA2, IB1,
IIA1) and no risk factors and negative nodes Adjuvant XRT indicated if large primary tumor, LVSI, deep
stromal invasion, +LN, +Sx Margins, and + parametrium
Chemo-radiation for higher stages or patients who are not candidates for hysterectomy Cisplatin based chemotherapy Chemo/XRT have shown a 30-50% decrease in risk of
death compared to XRT alone 3 trials have shown improved PFS and OS with
Chemo/XRT

Cervical Cancer Surveillance
Based on NCCN consensusCervical cytology Q3- 6 mos x 2 years, then
Q6 mos for 3- 5 years, then annuallyCareful surveillance due to increased risk for
secondary cancers at and near radiated sites
