A 57 yo female presents to the emergency room with a large pelvic mass. Answer the following questions regarding her management.
What will you look for on history and physical? HISTORY (name Risk Factors) • Age • Ethnicity (Ashkenazi Jewish, white) • LMP, menopause Status • PMH: Cancers: breast, uterine, ovarian, colon, lymphoma, DM, HTN, obesity, • PSH: TL, Ovarian cysts, OR/ pathology reports • FAMILY HX: breast, uterine, ovarian, Colon, lymphoma, endometriosis, fibroid • MEDICATIONS: no OCP, HRT • ALLERGIES: • HABITS: smoking ETOH, drugs • SOCIAL: occupation, marital status • POBS: GPTLA, nulliparity, infertility, IVF, did not breastfeed • PGYN: • early menarche, late menopause, regularity of cycles, PAP hx, STI’s/PID, PCOS, • Hx of pelvic radiation, last mamo/ colonoscopy) (BRCA, HNPCC, age of Dx) • benign gyn pathology (endometriosis, ov cysts, fibroids, adenomyosis), hot flushes, vag dryness, PM bleeding • HPI: • abd pain/bloating, N/V, urinary frequency / urgency/dysuria, constipation / diarrhea/dyschezia, bloody stool, early satiety / anorexia, vaginal bleeding, constitutional symptoms: fatigue, weight loss, weakness, anorexia. • Symptoms progression/duration • Activities of daily living/ functional status
PHYSICAL EXAM • VITAL SIGNS, height weight BMI, general appearance • LYMPHADENOPATHY: supraclavicular, inguinal, pelvic • HEENT: thyroid, nodes • CVS • RESP: pleural effusion • BREAST EXAM • ABDOMINAL EXAM: ascites, masses, tenderness • PELVIC, RECTAL AND PV/PR (cul de sac nodules/masses)
What work up you want to do? • CBC, T & S • Creatinine, BUN, lytes, LFT • CA-125, CEA, CA 19.9 (mucinous, pancreas), 15.3 (breast) • Pap test • Cultures, endometrial Bx if indicated • ULTRASOUND for RMI 2 score (TVUS and Abd) • CXR, ECG • r/o other primary as Hx indicates: Barium enema, colonoscopy, mammogram • UA, cytology, C&S if positive hx • BHCG • Paracentesis/ omental bx can be considered: often non diagnostic. Still need surgical staging • CT/ MRI/ bone scan/ PET not necessary pre-op if US and RMI score abnormal
What is your differential diagnosis of a pelvic mass? Benign (Ovarian/ Other Gyn/ GI/ GU) • Endometrioma • Dermoid • Cystadenoma • Functional ovarian cyst • Ruptured / hemorrhagic ovarian cyst • Fibroid, adenomyosis • TOA, hyrdosalpinx, paratubal cyst • Ectopic (pre menopausal) • Diverticulosis • Pelvic kidney MALIGNANT • Primary Ovarian CA (epithelial)- borderline, cystadenocarcinoma • Sex cord / stromal tumor (Granulosa cell causes PMBleed, SertoliLeydig) • Metastatic Ovarian (breast, stomach etc) • Endometrial CA, • Cervical mass/ cancer • Uterine Sarcoma • Fallopian Tube Ca • Colon • Lymphoma/ Leukemia • Germ cell tumors usually NOT in this age group (different OSCE)
What are the ultrasound criteria suggestive of an ovarian malignancy? • Multiloculated, complex mass • Solid echogenic components • Bilateral • Ascites • Peritoneal nodularities • > 5 cm • Thick septations • Papillary excrescences • Central vascularity on Doppler
List the specific criteria and scoring system for the RMI II. What is the specificity of this index? • RMI II = ultrasound score x [CA-125 level] x menopause score • RMI II > 200 high risk of malignancy, Refer to gyn onc. • List the components of the RMI 2 • U/S score: Multilocular cyst, presence of solid areas, bilaterality, presence of ascites, presence of intra-abdominal mets • 1 = 0 or 1 abnormality, 4 = 2 or > abnormalities • Menopausal score: • Premenopausal = 1 and Postmenopausal = 4 • Specificity of RMI II: 90% ppv = 80%
Your patient’s result show the following: • TVUS: bilateral ovarian masses, solid & cystic components and ascites • CA-125: 100 • How much is RMI score and how will you manage her?
Your patient’s result show the following: • TVUS: bilateral ovarian masses, solid & cystic components and ascites • CA-125: 100 • How much is RMI score and how will you manage her? • 4x4x100 = 1600 • Refer to Gynecology Oncology
What will be the proposed management by the GYN-ONC team for this 57 yo? • COMPREHENSIVE SURGICAL STAGING • Midline laparotomy • Peritoneal washings • Inspection/ palpation • Diaphragm, surface and parenchyma of liver, gallbladder, stomach, spleen, R+L kidney, R+L paracolic gutters, small bowel and mesentery, appendix, ascending, transverse, descending and rectosigmoid colon and mesentery, omentum, lesser sac • PALN and PLN, ovaries, tubes, uterus, bladder peritoneum and cul-de-sac. • TAH BSO frozen section • Retroperitoneal lymphadenectomy (pelvic, paraaorticnodes) • omentectomy • diaphragmatic scrapings / biopsies • Peritoneal biopsies of suspicious areas or adhesions • If no disease, multiple biopsies of peritoneum from cul-de-sac, paracolic gutters, bladder peritoneum, intestinal mesenteries
Pathology of frozen section result shows Grade 2 papillary serous adenocarcinoma of the ovary. The patient’s pelvic lymph nodes are positive. No mets are seen. What is her surgical stage? • Stage IIIA1
What will be the management for this patient? • Primary cytoreductive surgery Aiming for Optimal debulking (< 1cm macroscopic residual) • Chemotherapy: 6-9 cycles IV carboplatinum & paclitaxel • Or neoadjuvant chemo 3 cycles followed by interval debulking followed by adjuvant chemo for 3 cycles.
Name 3 serious side effects of Carboplatin, Cisplatin and Paclitaxol • Carbo: myelosuppression(esp Platelets), hypersensitivity, less N&V and neuropathy • Cisplatin: nephrotoxic, neuropathy, severe N&V, metallic taste, anorexia, ototoxicity, hypersensitivity, less hematologic toxicity than carbo • Paclitaxol: myelosuppression, hypersensitivity, neurotoxic, alopecia
Patient presented 15 months later with an evidence of recurrent disease and she asked you about surgerywhat is the role for secondary cytoreductive surgery? • No evidence of ascites or ascites less than 500 cc • Solitary site recurrence • Platinum sensitive disease • Prolonged disease free interval > 12 months
What is the definition of Platinum sensitive/ resistant/ refractory? • Platinum sensitive = no recurrence more than 6 months after completion of primary platinum based chemo • Platinum resistance = less than 6 months before recurrence • Platinum refractory = progression while on primary platinum chemo
what hereditary syndromes that you know can give rise to ovarian cancer ? • BRCA1, BRCA2 • HNPCC (LYNCH SYNDROME)
What % of Ovarian cancers are hereditary? Name 3 genetic mutations. • 5 – 10% of all ovarian cancers: BRCA1, BRCA2, HNPCC • lifetime risk of ovarian ca BRCA1 – 40%, BRCA2 – 25% • lifetime risk of breast ca for BRCA1 or BRCA 2 – 56-87% • Occur 10 years earlier than non-hereditary ca
What are the risks of ovarian and breast cancer in the general population and in BRCA patients? • Breast Ca: 12% vs 80% • Ovarian Ca: 1.3% vs 25% (BRCA2) vs 40% (BRCA1)
Describe management of pts with BRCA mutations • Annual or biannual TVUS, CA 125 and pelvic exam • Mammography starting at age 30 if strong family hx of breast ca alternating with MRI every 6 months. • Prophylactic BSO done at age 40, post-op risk reduced to 0.8%, doesn’t protect against peritoneal ca (4%), decreases risk of breast ca significantly, consider TAH BSO (reduce FT ca) • OCP: Women with BRCA mutations can reduce ovarian cancer risk by 60% • TL: reduces risk by 39%, decreases blood supply to ovary and decreases carcinogens passing via tube into pelvis • If documented HNPCC, periodic mammography, colonoscopy and endometrial biopsy and urine cytology
How is BRCA Prognosis different from other ovca patients • Improved overall survival for BRCA cancers • High grade • Papillary serous histology • More sensitive to radiation • More sensitive to chemotherapy • longer interval to recurrence
What type of ovarian Ca can you get after TAH BSO? • Primary peritoneal carcinoma
What is the risk of ovarian ca in HNPCC pts? & What % of hereditary ovca is due to HNPCC? • 3-fold increase risk in ovarian ca • 16% of hereditary ovarian ca
What decreases a woman’s risk of Ov Ca? • Surgery: TL, BSO, Salpingectomy • Decreased estrogenic effect: Multiparity, breastfeeding, OCP
