Clinical - Uterus Carcinoma Flashcards
Most common female genital tract malignancy
carcinoma of the uterus
Most common clinical presentation of carcinoma of the uterus
abnormal vaginal bleeding in peri/post menopausal women
Risk factors for carcinoma of the uterus
Obesity, unopposed estrogen, tamoxifen(breast estrogen R antagonist), nulliparity, diabetes, late menopause, PCOS, lynch syndrome(heriditary nonpolyposis colorectal cancer) EXTRA ESTROGEN EXPOSURE
Risk for carcinoma of the uterus decreased by:
ovulation, progestin therapy, combination BCPs, early menopause, multiparity LESS ESTROGEN EXPOSURE
How evaluate abnormal vaginal bleeding
Pelvic exam/pap smear
Endometrial sampling
transvaginal ultrasound -good if endometrial stripe<5mm
Fractional D&C
Endometrial hyperplasia treatment
intermittent/continuous progestin therapy w/ 3-6 month sample - depends on complexity and cytologic atypia
How is an endometrial carcinoma staged
Surgically - requires fractional D&C
Describe endometrial carcinoma stages
1 - confined to uterine corpus
a - endometrium, b < 1/2 myometrium c >1/2 myo
2 - invades endocervix/cervix
3 - in peritoneum, vagina, or lymph nodes
4 - distant metastases or inguinal lymph nodes
Prognosis of endometrial carcinoma
affected by grade and histology
1,2,3 - 95, 85, 70 - 5 year survival
80% favorable
What are the unfavorable endometrial carcinomas
papillary serous carcinoma, clear-cell carcinoma, squamous cell carcinoma, poorly differentiated carcinoma
Where can endometrial carcinomas spread?
inguinal lymph - internal/external iliac-common iliac-paraaortic lymph, transtubal spread to abdomen
Endometrial cancer treatment?
Depends on stage
1a/1b- TAH-BSO, peritoneal washings, remove large lymph nodes
1c/2 - TAH-BSO, cytology, and iliac/para-aortic node dissection +/- radiation
3/4 - surgical debulking+radiation+chemo
second most common, but most lethal cancer of female genital tract
ovarian cancer - most deaths of any gyn malignancy
Presenting symptoms of ovarian cancer
increasing girth, pelvic/abdominal fullness, vague pelvic discomfort - most present stage 3 or 4 age 50-70
dysuria, dyspareunia, constipation
PE - pelvic mass, ascites, abdominal mass
Increased risk of ovarian cancer
(regular ovulation) white race, nulliparity, late childbearing, late menopause, family history, BRCA genetic mutation
Decreased risk of ovarian cancer
(ovulation interrupted) oral contraceptives, multiparity, breast feeding, tubal ligation, hysterectomy
Ovarian cancer screening
no effective screening techniques
Ovarian cancer histology
80% epithelial (serous, mucinous, endometroid, clear cell)
10-15% germ cell (dysgerminomas, teratomas)
5% - gonadal-stromal (granulosa/theca cell, sertoli/leydig)
1% other (soft tissue, metastatic, Krukenberg)
How does ovarian cancer spread?
Peritoneal spread - all over abdominal cavity
Nodal - inguinal-internal iliac-common iliac-paraaortic
Ovarian cancer staging?
surgically 1 - confined to ovaries 2 - confined to pelvis 3 - confined to abdominal peritoneal surfaces/retroperitoneal lymph 4 - distant metastases
Ovarian cancer surgery
surgical cytoreduction and sampling
- TAH-BSO, washings for cytology, omentectomy, diaphragm scraping, sample peritoneum, paraaortic dissection, EXCISE any visible tumor(bowel prep)
Ovarian cancer post op
radiation and/or chemo
epithelial low grade - no further
high - platinum based chemo +/- paclitaxel
germ cell - plat chemo, bleomycin, etoposide
gonadal-stromal tumors - chemoresistant
ovarian cancer prognosis
Epithelial 1,2,3 - 75-95, 65, 20 @ 5 years
Germ cell 1,2,3 - 95, 80, 60-70
Gonadal-stromal 1 - 90
