Gynecologic oncology-Erin wright Flashcards
What is the most common CA in both men and women?
lung cancer
What is the MC cancer in women?
breast CA
How does CA occur?
- increased division of abnormal cells, or
- decreased apoptosis = this is how cancer occurs
- and loss of normal growth control, with multiple** mutations
Describe somatic mutations
-list ex’s
=sporadic mutations (Cancer)
-typically from exposure Smoking Environmental carcinogens Viruses Hormones Alcohol High fat diet
Describe germline mutations
=hereditary (cancer)
mutations you are born with
_________ is the key to dx and tx of CA
- *pathology
- Once you know cell type, you evaluate location and extent of cancer to determine staging
- You can then decide treatment or management options
CA cells spread in the body in a series of steps:
- growing into, or invading nearby normal tissue
- moving through the walls of nearby lymph nodes
- Traveling through lymphatic system and blood to other body parts
- Stopping in small blood vessels at a distant location, invading the blood vessel walls, and moving into surrounding tissue
- Growing in tissues until a tiny tumor forms
- Causing new blood vessels o grow, which creates a blood supply that allows the tumor to cont. to grow
Bladder CA mets to–>
bone
liver
lung
Breast CA mets to–>
bone
brain
liver lung
TNM staging=
T – Extent of the primary tumor
N- absence or presence of regional lymph node involvement
M- absence or presence of distant metastases
Primary tumor (T):
- TX=
- T0=
- T1..
TX: Main tumor cannot be measured.
T0: Main tumor cannot be found.
T1, T2, T3, T4: Refers to the size and/or extent of the main tumor. Thehigher the number after the T, the larger the tumor or the more it has growninto nearby tissues. T’s may be further divided to provide more detail, suchas T3a and T3b.
Regional lymph nodes (N):
-NX=
NX: Cancer in nearby lymph nodes cannot be measured.
N0: There is no cancer in nearby lymph nodes.
N1, N2, N3: Refers to the number and location of lymph nodes that containcancer. The higher the number after the N, the more lymph nodes thatcontain cancer.
Distant Metastasis (M)
MX: Metastasis cannot be measured.
M0: Cancer has not spread to other parts of the body.
M1: Cancer has spread to other parts of the body.
Tumor grade:
- GX=
- G1=
GX: Grade cannot be assessed (undetermined grade)
G1: Well differentiated (low grade)
G2: Moderately differentiated (intermediate grade)
G3: Poorly differentiated (high grade)
G4: Undifferentiated (high grade)
Goals of Treatment:
- Prophylaxis:
- Cure ?
Prophylaxis:
-Preventative surgery. The goal of prophylactic surgery is to remove additionaltissue or organs from the body which, although it currently shows no signs ofcancer, carries a high risk of developing cancer in the future
Cure:
- -Aggressive treatment to obtain best outcome for cure (early stage)
- Cancer type is responsive to treatment
Goals of Tx:
- control?
- Palliative?
- Management of cancer to diminish tumor burden or spread
- Maintain quality of life
- Increase length of life
Palliative: Control cancer causing symptoms, improve QOL
Mainstays of CA tx: (list the 4 realms)
- Surgical: **Curative intent, palliative intervention
- Radiation: Localized theray for solid tumors or mets, total body for SCT
- Chemotherapy: neo-adjunct, adjuvant, palliative
- Biotherapy: immunotherapy, targeted therapy, gene therapy
Endometrial Cancer – Epidemiology / Risk:
- How common?
- ___% lifetime risk of developing endometrial CA
- Risk increases with _______
- MC gynecologic malignancy in developed countries
- 3%
- advancing age
Endometrial CA:
- age over ___ indicates increased risk
- _____ syndrome increases risk
- _______ therapy increases risk
- > 45 yo
- lynch syndrome, unopposed estrogen therapy increases risk
T/F: use of tamoxifen increases risk for endometrial CA
true
Endometrial Cancer – Clinical Presentation:
-cardinal sx?
-
- **abnormal uterine bleeding
- -70-90% of Pts w/ endometrial CA present w this Sx
- *6-19% of women with postmenopausal vaginal bleeding have endometrial cancer
- Any postmenopausal bleeding should prompt evaluation for endometrial cancer
Endometrial Cancer:
-PE findings=
Typically enlarged uterus or palpable mass is not present
Endometrial Cancer – Diagnostic Evaluation:
- labs?
- US?
- Gold standard test?
- Hgb/Hct– eval for anemia
- Hcg– r/o pregnancy
- tumor markers–CA125
-**pelvic US–> ***shows Endometrial thickening or stripe >4mm indicates need for biopsy
-*****Endometrial sampling – GOLD STANDARD
Office biopsy vs hysteroscopy vs dilation and curettage
endometrial CA- prognosis
- if you catch this early, GOOD survival rate
- most women get caught early cuz they are symptomatic
Endometrial Cancer – Screening
-is routine screening of asymptomatic women advised?
NO, dont screen asymptomatic women.
- High percentage of symptomatic women with disease
- Majority diagnosed with disease confined to the uterus
- 90% five year survival rate
- No screening test that is sensitive and specific
Lynch syndrome holds lifetime risk of developing endometrial cancer at ____%
12-54%
–Risk-reducing hysterectomy
Cervical CA:
- how common?
- _____ is detected in 99.7% of cervical CA’s
- 3rd MC gynecologic malignancy & cause of death in US
- 2nd MC female malignancy and cause of death from CA in countries w/out access to screening
-**HPV
Cervical Cancer – Risk Factors
Early onset sexual activity
Multiple sexual partners
High risk sexual partner
Known HPV positive or multiple sexual partners
History of sexually transmitted infections
History of vulvar or vaginal squamous intraepithelial neoplasia or cancer
Immunosuppression
65 yo woman with vaginal bleeding
–work them up for?
**ENDOMETRIAL CA
Cervical CA: HPV is detected in 99.7% of cervical cancers
–Vaccinations have ______ incidence
- decreased cervical cancer incidence by 75% over the last 50 years
